3 Introduction 1.0

4 Introduction 1.0 These signage guidelines should be read in tandem with the Department of Municipal Affairs Request for Proposal or RFP for the manufacture and installation of street signs. The guidelines are intended to enable signage suppliers prepare a comprehensive proposal, including a detailed financial proposal, for providing the various signs necessary for the practical implementation of the Emirate s adopted addressing standard. The addressing standard allocates specific street addresses to properties in a structured manner, enabling a destination to be described and identified in terms of its unique street address. The standard sets out the policy and details of the addressing system, including conventions for street naming and property numbering, to facilitate locating of destinations by all sectors of the community, government and commercial services. Design guidelines for street signs have a fundamental role in supporting the addressing standard and are an essential tool for implementing the addressing system. Signs displaying names of districts are important in identifying an area in which a destination is located. The final approach to the destination relies on information on street name signs, to identify the correct street and help locate the specific destination within that street, including the property number. These guidelines present information and design specifications for the range of signs involved: four categories of street name signs; building address signs; and district signs. There is also guidance for the implementation of street name signs in the road environment. The principles for sign layout design, applied graphics and choice of typeface are based on initial proposals put forward by Abu Dhabi Municipality. The guidelines also include specifications for materials, signage hardware and fixing. They do not cover route direction and guidance sign specifications, which can be found in separate manuals dealing with the broader scheme of traffic control devices.

5 Core signing elements 2.0

6 Core signing elements Sign types 2.1 Sultan Bin Zayed St Overhead street sign Al Nahyan Sultan Bin Zayed St Main street sign The purpose of street name signs is complementary to the main role of direction and guide signs for vehicle users and pedestrians, and their design and placement within the road environment must work within the overall signs scheme. Sign categories There are five main categories of street name signs for use in different locations: overhead signs; main street signs; internal street signs; cul-de-sac signs; and rural street signs, as illustrated. All categories of street name signs share common graphic elements designed to present a consistent, coherent visual appearance across the signing system overall. Sign Shape The basic shape for all street name signs is rectangular with the long axis horizontal. Sign corners are chamfered as illustrated to give a distinctive, recognisable appearance. Sign dimensions Each category of street name sign is available in a range of approved sizes based on legibility requirements, depending upon the sign s location. For each category the length of the street name determines the length of the sign. Sign dimensions and measurements for sign face elements, including type sizes and spacing, are given in subsequent sections of these guidelines. This approach gives a minimum range of standard sign sizes for ease of manufacturing and assembly that are capable of meeting most addressing requirements Sultan Bin Zayed St Internal street sign 5 15 Sultan Bin Zayed St Cul-de-sac sign Sultan Bin Zayed St Rural street sign

7 Core signing elements Colour 2.2 The rationale for the selected colour palette is to maximise clarity and recognition to assist street identification. Sign colours have been chosen to aid contrast and definition, especially in conditions of bright sunlight. Primary colour palette The permitted colour combination for all street name signs is white text against a dark blue background, irrespective of type of sign. The dark blue specified achieves a 70 percent contrast value in line with international best practice in signing design. The selection of this colour combination ensures street name signs remain consistent with other major types of guide signs used throughout the Emirate. It is important the colour combination of sign categories is consistent to maximise opportunities for instant recognition. Pantone 188 Secondary colour palette A secondary colour in dark red has been specified to highlight district names and property number ranges on street signs when shown. Colour specifications Paint and industrial finishes are specified using RAL colours. However, the Pantone Matching System (PMS) is used for matching print, vinyl and other finishes for sign face colours. Vinyl colours must be matched using the Pantone specification. The blue is specified as PMS 295 and the red colour is PMS 188. Pantone 295

8 Core signing elements Typeface 2.3 Both Arabic and Latin typefaces are used on all categories of street name signs with Arabic always shown above the Latin text. AXt Manal Bold أ ب ت ث ج ح خ د ذ ر ز س ش ص ض ط ظ ع غ ف ق ك ل م ن ه و ي آ ا ا أ ا ا إ اا ا ا ب ب ب ت ت ت ث ث ث ج ج ج ح ح ح خ خ خ چ چ چ د ذ ر ز ى س س س ش ش ش ص ص ص ض ض ئ ض ط ط ظ ظ ع غ ع غ ع غ ف ف ف ق ق ق ڤ ڤ ڤ ك ل م م م ن ن ن ه ة و و ي ي ي ي ي ي ي ى ك ل ل ل لا لا لا لا لا لا لا لا لا لا AXt Manal Bold AXt Manal Bold is the Arabic typeface used on traffic control signs throughout the Emirate of Abu Dhabi and specified by ADM for street name signs for reasons of continuity. The typeface is based on a Naskh script style and has deep descenders compared with other Arabic fonts, and this detail can have a consequential effect on sign dimensions. Clearview Hwy-3-W Clearview is a Latin typeface designed for use on highway signs in the USA. The letterforms are clearly legible and are widely spaced, which again can have a consequential effect on sign dimensions. Numerals are always shown using the Latin typeface.

9 Overhead street signs 3.0

10 Overhead street signs Modules Overhead street name signs are designed to be highly visible at intersections on main arterial or sub-arterial routes in the Emirate to identify named streets. They are consequently much larger than other categories of street name signs. 575 Module size Overhead street name signs are based on an individual module or tiling size of 575mm x 500mm. Modules are combined using a minimum of three modules or more to create the required signs. Signs comprising a single module or two modules are not permitted Sign sizes The sign height is always 575mm and the sign length ranges from a minimum of 1,500mm (three modules) and 2,000mm (four modules), up to 2,500mm (five modules) or longer, depending upon the number of characters in the street name. Where the street name does not fit onto a complete module, an extra module should be added to create a longer sign. See section 3.3 Typography Ideally street names should be accommodated within three or four module overhead street signs. Five module signs are reserved for exceptionally long street names and should not be used otherwise. It is not recommended using signs longer than five modules because of load bearing limitations affecting safe support

11 Overhead street signs Layout 3.2 Margins on overhead street signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins, as well as the top and bottom margins, are 75mm. The margins are clear areas and should not include text or other graphic elements under any circumstances. See next page: 3.3 Typography

12 Overhead street signs Typography 3.3 Text layout All signs are laid out in Arabic and Latin text, with the text centred for ease of reading. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the upper and lower margins, as illustrated. If one or more characters in a street name falls within the 75mm margin at the left or right of the sign, an additional module should be added and the text centred within the combined modules of the longer sign. No supplemental information, such as street numbers or district branding, is shown on overhead street name signs Text size To ensure legibility given the reading distances involved, potential speed of travel and the height and location of overhead name signs, sign face text must comply with the size specifications on this page. The Alif height for Arabic text is 150mm and the x-height for Latin text is 100mm, as illustrated. There is a margin of 150mm between the baseline of the Arabic text and the x-height of the Latin text

13 Overhead street signs Typography 3.3 This page shows the sign text reversed white out of the dark blue sign background for overhead street name signs, as illustrated. No borders should be applied to the signs as the margins at left and right, and at top and bottom, are clear areas devoid of content apart from the dark blue sign colour, as shown. Sultan Bin Zayed St

14 Overhead street signs Sign heights and locations 3.4 Overhead street name signs are suspended from posts or mast arms at traffic intersections on major routes to indicate streets at particular junctions. These routes are typically multi-lane highways with intersections controlled by traffic lights. Overhead street name signs are double sided so they can be read from both directions of travel. Location and clearance The signs should be located as close as possible to the intersection and clearly visible during daytime and nighttime. For overhead street name signs a minimum clearance of 5,500mm measured from the road surface to the base of the sign is required, as illustrated. For overhead street name signs mounted on mast arms, signs may be mounted onto the mast arm or under the mast arm in order to meet site-specific considerations. The base of the street name sign should be parallel with the road surface. The exact placement of overhead street name signs may vary depending on whether the support pole is placed in the median or on the kerb-side of a street. 5500

15 Main street signs 4.0

16 Main street signs Modules Like overhead street name signs, main street signs are designed to be highly visible on major routes or Main streets in the Emirate to identify named streets. They are usually double sided signs post mounted at the side of main streets and their size is commensurate with legibility requirements, given they have to be easily read by drivers in moving vehicles. 589 Module size Main street name signs are based on an individual module or tiling size of 589mm x 400mm. Modules are combined using a minimum of three modules up to a preferred maximum of four modules to create the required signs, although the use of more modules is acceptable to accommodate very long street names. Signs comprising a single module or two modules are not permitted Sign sizes The sign height is always 589mm and the sign length ranges from a minimum of 1,200mm (three modules) and 1,600mm (four modules), up to 2,000mm (five modules) or longer, depending upon the number of characters in the street name. Where the street name does not fit onto a complete module, an extra module should be added to create a longer sign. See section 3.3 Typography. 589 Ideally street names should be accommodated within three or four module main street signs. Five module signs are reserved for exceptionally long street names and should not be used otherwise, longer signs are not recommended if they can be avoided. Signs comprising five or more modules should be double-post mounted for reasons of safety and to provide adequate support, as illustrated in section 3.4 Sign heights and locations

17 Main street signs Layout 4.2 Margins on main street signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins, as well as the bottom margin, are 60mm. These margins are clear areas and should not include text or other graphic elements under any circumstances. Main street name signs include the district name positioned within the top margin or dark red coloured band measuring 124mm. In certain circumstances property number ranges can also be shown within this band. This upper area is separated from the rest of the sign by a solid line. See next page: 3.3 Typography

18 Main street signs Typography Text layout All signs are laid out in Arabic and Latin text, with the text centred for ease of reading. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated If one or more characters in a street name falls within the 60mm margin at the left or right of the sign, an additional module should be added and the text centred within the combined modules of the longer sign Supplemental information Main street name signs include supplemental information showing the district name in Arabic and Latin text centred within the sign s upper band, as illustrated. If for some reason a district name cannot be used in the top band, for example if the sign is located on a border between districts, number ranges can be shown instead to the top left and right within the sign s upper band If space allows and there is an identified need to do so, it is permissible to show a district name to the upper right of the sign with a single number range on the upper left, as illustrated Where shown, directional arrows to the left and right are positioned in a 60mm margin measured from the edge of the chamfered corners When a dual-language district name is longer than the street name, thus requiring a longer sign than would otherwise be necessary, a single language district name is recommended. Depending upon local needs, the text used for single language district names can be either Arabic or Latin Text size To ensure legibility given the reading distances involved, potential speed of travel and the location of main street signs, text on sign faces must comply with the size specifications on this page. The Alif height for Arabic text is 120mm and the x-height for Latin text is 80mm, as illustrated. There is a margin of 120mm between the baseline of the Arabic text and the x-height of the Latin text. Numerals are shown at a height of 48mm

19 Main street signs Typography 4.3 Al Nahyan Sultan Bin Zayed St This page shows the sign text reversed white out of the dark blue sign background for versions of main street name signs, as illustrated. The dark red coloured band at the top of the sign is used to show the district name and in certain circumstances property number ranges and corresponding directions. A white line separates the district name and property number range information from the rest of the sign. No borders should otherwise be applied to the sign as the margins at left and right, and at the bottom, are clear areas devoid of content apart from the dark blue sign colour, as illustrated Sultan Bin Zayed St Al Nahyan Sultan Bin Zayed St

20 Main street signs Sign heights and locations 4.4 Location and clearance Main street name signs should be cantilever mounted onto posts located as close as possible to traffic intersections on major routes to indicate streets at particular junctions. The signs should be clearly visible during daytime and nighttime. For main street signs a minimum clearance of 2,200mm measured from the ground to the base of the sign is required, as illustrated. Main street signs are double sided so they can be read from both directions of travel. Cantilevered signs are always preferred for intersections, orientated at right angles to approaching traffic so they can be read properly, and indicating the street direction. For skewed approaches, not at a right angle, signs should face approaching traffic and not point directly along the skewed approach. The preferred maximum size for cantilevered main street signs is three modules. Signs comprising four sign modules should ideally be centre-post mounted or can be mounted using twin posts at either end of the sign. Longer signs comprising five or six modules must be mounted using twin posts. 2200

21 Main street signs Sign heights and locations 4.4 Where two main street signs are required at the same intersection, they should be positioned adjacent to each other, as illustrated. To help differentiate between the different street names, the main street sign on the right should be placed higher at a distance of 2,810mm from the ground to the base of the sign so the base of the second sign aligns with the top of the first. Single main street signs should always be post mounted at a height of 2,200mm to the base of the sign

22 Main street signs Sign heights and locations 4.4 Centre-post mounting is recommended when four modules are used to make a sign. Centre-post mounting is always more stable than cantilever mounted signs so signs comprising three sign modules can also be centre mounted if preferred. 2200

23 Main street signs Sign heights and locations 4.4 Ideally, signs comprising four modules should always be centre-post mounted, as illustrated. Five module signs or longer must be centre-post or twin-post mounted to ensure adequate support. Where combined main street signs and internal street signs mounted onto a single post are required at the same junction, the preference is for internal street signs to be placed higher than main street signs at a distance of 2,840mm from the ground to the base of the sign. The lower sign should always be mounted at a height of 2,200mm to the base of the sign. The illustration shows four single sided signs centre-post mounted at a typical T-junction between a main street and an internal street

24 Main street signs Sign heights and locations 4.4 Signs comprising five modules can be mounted using twin posts, with a post at either end of the sign. Signs comprising six or more modules must be twin post-mounted to ensure adequate support. 2200

25 Internal street signs 5.0

26 Internal street signs Modules Internal street signs are designed for use on secondary streets or lanes, where people will be driving more slowly than on major routes or on foot. Consequently, signs in this category can be a smaller size than main street signs to be sufficiently visible to identify named streets. Internal street signs are usually double sided signs post mounted at the side of streets and can also be wall mounted in certain situations. The majority of signs required for the Emirate s addressing system are internal street signs Module size Internal street name signs are based on an individual module or tiling size of 434mm x 300mm. Modules are combined using a minimum of three modules up to a preferred maximum of four modules to create the required signs, although the use of more modules is acceptable to accommodate very long street names. Signs comprising a single module or two modules are not permitted Sign sizes The sign height is always 434mm and the sign length ranges from a minimum of 900mm (three modules) and 1,200mm (four modules), up to 1,500mm (five modules) or longer, depending upon the number of characters in the street name. Where the street name does not fit onto a complete module, an extra module should be added to create a longer sign. See section 4.3 Typography. 434 Ideally street names should be accommodated within three or four module internal street signs. Five module signs are reserved for exceptionally long street names and should not be used otherwise, longer signs are not recommended if they can be avoided. Signs comprising five modules should be centre-post mounted for reasons of safety and to provide adequate support, as illustrated in section 4.4 Sign heights and locations

27 Internal street signs Layout 5.2 Margins on internal street signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins, as well as the bottom margin, are 45mm. These margins are clear areas and should not include text or other graphic elements under any circumstances. Internal street name signs include property number ranges positioned within the top margin or dark red coloured band measuring 84mm. This upper area is separated from the rest of the sign by a solid line. See next page: 4.3 Typography

28 Internal street signs Typography 5.3 Text layout All signs are laid out in Arabic and Latin text, with the text centred for ease of reading. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated. If one or more characters in a street name falls within the 45mm margin at the left or right of the sign, an additional module should be added and the text centred within the combined modules of the longer sign. Supplemental information Internal street name signs include supplemental information showing property number ranges to the top left and right within the sign s upper band. Directional arrows to the left and right are positioned in a 45mm margin measured from the edge of the chamfered corners. District names are not shown on internal street signs Text size To ensure legibility given the reading distances involved, mode of travel and the location of internal street signs, text on sign faces must comply with the size specifications on this page. The Alif height for Arabic text is 90mm and the x-height for Latin text is 60mm, as illustrated. There is a margin of 90mm between the baseline of the Arabic text and the x-height of the Latin text. Numerals are shown at a height of 36mm

29 Internal street signs Typography 5.3 This page shows the sign text reversed white out of the dark blue sign background for an internal street name sign, as illustrated. The dark red coloured band at the top of the sign is solely used to show property number ranges and corresponding directions. A white line separates the property number range information from the rest of the sign. No borders should otherwise be applied to the sign as the margins at left and right, and at the bottom, are clear areas devoid of content apart from the dark blue sign colour, as illustrated Sultan Bin Zayed St

30 Internal street signs Sign heights and locations 5.4 Location and clearance Internal street name signs are mounted on posts typically located at intersections to main access routes and at intersections to minor streets. The signs should be clearly visible during daytime and nighttime. Like main street signs, a minimum clearance of 2,200mm measured from the ground to the base of the sign is required for internal street signs. Internal street name signs are double sided signs mainly cantilevered from posts to indicate streets at particular junctions and capable of being read from both directions of travel. The preferred maximum size for cantilevered internal street signs is four modules although ideally, internal street signs longer than three modules should be centre-post mounted as illustrated. Longer signs comprising five or six modules must always be centre-post mounted (or even mounted on twin posts) for reasons of stability

31 Internal street signs Sign heights and locations 5.4 Where two internal street signs are required at the same intersection, they should be positioned adjacent to each other, as illustrated. To help differentiate between the different street names, the internal street sign on the right should be placed higher at a distance of 2,660mm from the ground to the base of the sign so the base of the second sign aligns with the top of the first. Single internal street signs should always be post mounted at a height of 2,200mm to the base of the sign

32 Internal street signs Sign heights and locations 5.4 Signs comprising five or more modules should be centre-post mounted, as illustrated. Where two internal street signs mounted onto a single post are required at the same junction, the preference is for the sign parallel with the main thoroughfare to be placed higher than the sign facing oncoming traffic at a distance of 2,690mm from the ground to the base of the sign. The lower sign should always be post mounted at a height of 2,200mm to the base of the sign. The illustration shows four single sided signs centre-post mounted at a typical T-junction between two internal streets

33 Internal street signs Sign heights and locations 5.4 Wall mounted signs In certain circumstances where a property is street facing, and not set back from the public thoroughfare, internal street signs can be wall mounted. Like post mounted signs, wall signs should be affixed at a maximum height of 2,200mm from the ground to the base of the sign. A horizontal clearance of 200mm should be allowed from the corner of the property to the edge of the sign, as illustrated. 200 For exterior walls higher than 1,500mm but too low to accommodate signs at 2,200mm, signs should be affixed to the wall at the highest point with a clearance of 100mm from the top edge of the sign to the top of the wall. If the wall is less than 1,500mm high, internal street signs should be post mounted otherwise they would be too low down to be easily read. Similarly if the wall is some distance from the property, the use of post mounted signs is recommended. Max 2200

34 Cul-de-sac signs 6.0

35 Cul-de-sac signs Modules Cul-de-sac signs are designed for use on internal streets and lanes with a closed ending. Smaller cul-de-sac streets do not have their own names and are extensions of the streets from which they are accessed. The signs include the access street name (at a small size) and are primarily used to indicate the number ranges of dwellings or buildings in the cul-de-sac As these signs show less information than internal street signs, they are proportionately smaller in size. Cul-de-sac signs are usually double sided signs cantilever mounted onto posts at the side of streets or on median dividers and can also be wall mounted in certain situations Module size Cul-de-sac signs are based on an individual module or tiling size of 261.5mm x 150mm. Modules are combined using a minimum of three modules up to a preferred maximum of four modules to create the required signs, although the use of more modules is acceptable to accommodate very long street names. Signs comprising a single module or two modules are not permitted Sign sizes The sign height is always 261.5mm and the sign length ranges from a minimum of 450mm (three modules) and 600mm (four modules), up to 750mm (five modules) or longer, depending upon the number of characters in the street name. Where the street name does not fit onto a complete module, an extra module should be added to create a longer sign. See section 5.3 Typography

36 Cul-de-sac signs Layout 6.2 Margins on cul-de-sac signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins, as well as the bottom margin, are 30mm. These margins are clear areas and should not include text or other graphic elements under any circumstances. Cul-de-sac name signs include a property number range positioned within the top margin or dark red coloured band measuring 84mm. This upper area is separated from the rest of the sign by a solid line. See next page: 5.3 Typography

37 Cul-de-sac signs Typography 6.3 Text layout All signs are laid out in Arabic and Latin text, with the text centred for ease of reading. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated. If one or more characters in a street name falls within the 30mm margin at the left or right of the sign, an additional module should be added and the text centred within the combined modules of the longer sign. Supplemental information Cul-de-sac signs include supplemental information showing a property number range either to the top left or right within the sign s upper band. Directional arrows to the left or right are positioned in a 45mm margin measured from the edge of the chamfered corners Text size To ensure legibility given the reading distances involved, mode of travel and the location of cul-de-sac signs, text on sign faces must comply with the size specifications on this page. The Alif height for Arabic text is 45mm and the x-height for Latin text is 30mm, as illustrated. There is a margin of 45mm between the baseline of the Arabic text and the x-height of the Latin text. For consistency with internal street signs numerals are shown at the same height of 36mm

38 Cul-de-sac signs Typography 6.3 This page shows the sign text reversed white out of the dark blue sign background for cul-de-sac signs, as illustrated. The dark red coloured band at the top of the sign is solely used to show the property number range and corresponding direction. A white line separates the property number range information from the rest of the sign. No borders should otherwise be applied to the sign as the margins at left and right, and at the bottom, are clear areas devoid of content apart from the dark blue sign colour, as illustrated Sultan Bin Zayed St

39 Cul-de-sac signs Sign heights and locations 6.4 Location and clearance Cul-de-sac name signs are double sided signs cantilever mounted on posts located at entrances to cul-de-sacs from minor streets or internal lanes. No other form of post mounting should be required for this category of smaller name signs. The signs should be clearly visible during daytime and nighttime. Like main and internal street signs, a minimum clearance of 2,200mm measured from the ground to the base of the sign is required for cul-de-sac signs. 2200

40 Rural street signs 7.0

41 Rural street signs Modules Rural farming communities may be laid out in a grid pattern or established along an unplanned network of streets. A plot numbering system generally applies to each farm. Access to farm plots can be via a farm street or lane. Street signs are placed on approaching routes and at intersections to farm lanes to help people locate the farm or plot required. As these signs show less information than other categories of street signs, they are proportionately smaller in size. 217 Rural street signs are usually double sided signs cantilever mounted onto posts at the side of streets and can also be wall mounted in certain situations Module size Rural street signs are based on an individual module or tiling size of 217mm x 150mm. Modules are combined using a minimum of three modules up to a preferred maximum of four modules to create the required signs. Signs comprising a single module or two modules are not permitted. 600 Sign sizes The sign height is always 217mm and the sign length ranges from a minimum of 450mm (three modules) and 600mm (four modules), up to 750mm (five modules) or longer, depending upon the number of characters in the street name. Where the street name does not fit onto a complete module, an extra module should be added to create a longer sign. See section 6.3 Typography

42 Rural street signs Layout 7.2 Margins on rural street signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins are 30mm and the bottom margin is 22.5mm. These margins are clear areas and should not include text or other graphic elements under any circumstances. Rural street signs include property number ranges positioned within the top margin or dark red coloured band measuring 42mm. This upper area is separated from the rest of the sign by a solid line. See next page: 6.3 Typography

43 Rural street signs Typography 7.3 Text layout All signs are laid out in Arabic and Latin text, with the text centred for ease of reading. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated. If one or more characters in a street name falls within the 30mm margin at the left or right of the sign, an additional module should be added and the text centred within the combined modules of the longer sign. Supplemental information Rural street signs include supplemental information showing property number ranges to the top left and right within the sign s upper band. Directional arrows to the left and right are positioned in a 22.5mm margin measured from the edge of the chamfered corners Text size To ensure legibility given the reading distances involved, mode of travel and the location of rural street signs, text on sign faces must comply with the size specifications on this page. The Alif height for Arabic text is 45mm and the x-height for Latin text is 30mm, as illustrated. There is a margin of 45mm between the baseline of the Arabic text and the x-height of the Latin text. Numerals are shown at a height of 18mm

44 Rural street signs Typography 7.3 This page shows the sign text reversed white out of the dark blue sign background for rural street signs, as illustrated. The dark red coloured band at the top of the sign is solely used to show property number ranges and corresponding directions. A white line separates the property number range information from the rest of the sign. No borders should otherwise be applied to the sign as the margins at left and right, and at the bottom, are clear areas devoid of content apart from the dark blue sign colour, as illustrated Sultan Bin Zayed St

45 Rural street signs Sign heights and locations 7.4 Location and clearance Rural street signs are double sided signs usually cantilever mounted on posts located at entrances to farm streets and lanes. No other form of post mounting should be required for this category of shorter name signs. The signs should be clearly visible during daytime and nighttime. A minimum clearance of 2,200mm measured from the ground to the base of the sign is required for rural street signs. 2200

46 Rural street signs Sign heights and locations 7.4 Wall mounted signs In certain circumstances where a property is street facing, and not set back from the public thoroughfare, rural street signs can be wall mounted. Like post mounted signs, wall signs should be affixed at a maximum height of 2,200mm from the ground to the base of the sign. A horizontal clearance of 200mm should be allowed from the corner of the property to the edge of the sign, as illustrated. For exterior walls higher than 1,500mm but too low to accommodate signs at 2,200mm, signs should be affixed to the wall at the highest point with a clearance of 100mm from the top edge of the sign to the top of the wall. 200 Where possible, wall signs should be used wherever there is insufficient space to use a post mounted sign, either at intersections or by the side of the road. Max 2200

47 Building address signs 8.0

48 Building address signs Modules Building address signs are designed for use outside buildings and residential addresses to indicate property numbers. These signs are usually centre-mounted on posts at the side of streets and can also be wall mounted in certain situations. Module and sign sizes There are two module sizes for building address signs. Both modules share a sign height of 239mm, with the shorter sign having a width of 250mm and the longer sign 400mm. The number of digits in the property number determines the size of module used

49 Building address signs Layout Margins on building address signs are determined by the size of the chamfered corners, as illustrated. The left and right hand margins, as well as the top margin, are 30mm. These margins are clear areas and should not include text or other graphic elements under any circumstances. 30 Building address signs include a dark red coloured band within the bottom margin measuring 84mm. This lower area is separated from the rest of the sign by a solid line. See next page: 7.3 Typography

50 Building address signs Typography Text layout Building address signs contain only numerals shown using the Clearview typeface without any Arabic or Latin text. Numerals are centred in the upper part of the sign for ease of reading and their positioning is determined by the horizontal margins, as illustrated The smaller sign 239mm x 250mm is for property numbers comprising one or two digits. The larger sign 239mm x 400mm should be used for property numbers comprising three or four digits. Text size To ensure legibility given the reading distances involved, mode of travel and the location of building address signs, numerals on sign faces must comply with the size specifications on this page. The numeral height is 90mm for both sizes of building address signs

51 Building address signs Typography 8.3 This page shows the sign numerals reversed white out of the dark blue sign background for the two sizes of building address signs illustrated. A white line separates the dark red coloured band from the rest of the sign. 12 No borders should otherwise be applied to the sign as the margins at left and right, and at the top, are clear areas devoid of content apart from the dark blue sign colour, as illustrated. 1234

52 Building address signs Sign heights and locations 8.4 Location and clearance Building address signs can be either post mounted or wall mounted depending on the distance of the property/building from the road edge. For commercial buildings or domestic buildings without a garden wall, building address signs will normally be affixed directly to the building. For domestic properties that do have a garden wall, the sign must be fixed to that wall. If that wall or the building is more than 10m from the road edge the sign will be mounted on a post. Post mounted signs use a central fixing position. (End mounted or cantilevered signs are not considered necessary for building address signs.) Post mounted signs should be clearly visible during daytime and night time. A minimum clearance of 1,250mm measured from the ground to the base of the sign is required for building address signs mounted on posts

53 Building address signs Sign heights and locations 8.4 If the building, garden wall or property is close to the street, building address signs can be mounted directly onto the wall as illustrated. Wall mounted signs should be positioned at a maximum height of 2,200mm measured from the ground to the base of the sign and adjacent to the property entrance. Unless dictated by other factors, the signs will be placed to the right hand side of the main entrance, front door or gate. A lower placement for building address signs is permitted on walls depending upon the height of the wall and whether there is insufficient space to use a post mounted sign. If the wall is less than 1,500mm high then the building address sign should be post mounted. 2200

54 Building address signs Sign heights and locations 8.4 When a sign placed to the right hand side of an entrance is obscured by other structures or foliage then the sign should be placed on the left hand side. The height of the sign should remain at 2,200mm to the bottom of the sign face

55 Building address signs Sign heights and locations 8.4 Option 3 On commercial buildings like shops and offices or apartment blocks the building address sign should also be placed to the right hand side of the entrance at the heights indicated. If this location is again obscured or if some other structure prevents the sign being placed in this position then it should be placed on the left hand side as shown. If both sides of the entrance are otherwise unsuitable as sign location positions then the sign should be placed centrally above the entrance or door. In all cases, the minimum distance between the door frame or entrance edge and the edge of the sign should be 50mm; And the maximum distance should be 100mm. Option 2 Option

56 Building address signs Sign heights and locations 8.4 With rows of shops the building address signs should again be positioned, for preference, to the right hand side of any glazed frontage following the distance and spacing rules shown on earlier pages. If the arrangement of the shop fronts makes this difficult then the signs can again be positioned to the left hand side. If necessary the building address sign can be located above the glazed frontage and even inside the shop name panel if this is the only option. In all cases, the overriding priority must be given to ensuring that the property number is clearly associated with the shop itself. Option 2 Option

57 District signs 9.0

58 District signs Modules 9.1 District signs are designed for use at district boundaries to identify the area through which motorists and other vehicle users are travelling. These signs are usually mounted on twin posts in the median strip on main arterial or sub-arterial routes in the Emirate 1200 Module and sign sizes There are two module sizes for district signs. The smaller sign face is 1,220mm x 900mm, which is in proportion to signing modules for internal street signs, and the larger sign face is 1,625mm x 1,200mm, proportional with signing modules for main street signs. The larger sign is always the preferred size but the use of the smaller sign may be more appropriate depending on site-specific considerations

59 District signs Layout 9.2 Margins on district signs are determined by the size of the chamfered corners, as illustrated. For the smaller sign face, the left and right hand margins, as well as the top and bottom margins, are 45mm. For the larger sign face, the left and right hand margins, as well as the top and bottom margins, are 60mm. These margins are clear areas and should not include text or other graphic elements under any circumstances There are two typographic layouts depending on whether a district name requires one or two lines to fit on the sign. See section 8.3 Typography

60 District signs Typography Single line name 9.3 Text layout District signs show the Department of Municipal Affairs crest centred within the upper portion of the sign face, as illustrated. The lower portion of the sign face is laid out in Arabic and Latin text, with the text centred on a single line for each language. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated. A horizontal line separates the upper and lower portions of the sign face Text size To ensure legibility given the reading distances involved, potential speed of travel and the location of district signs, sign face text must comply with the size specifications on this page. For the smaller sign, the Alif height for Arabic text is 90mm and the x-height for Latin text is 60mm. The Alif height for the larger sign is 120mm and the x-height 80mm, as illustrated The smaller sign has a margin of 120mm between the baseline of the Arabic text and the x-height of the Latin text, and the larger sign a margin of 160mm

62 District signs Typography Double line name 9.3 Text layout District signs show the Department of Municipal Affairs crest centred within the upper portion of the sign face, as illustrated. The lower portion of the sign face is laid out in Arabic and Latin text, with the text centred on two lines for each language. Arabic text is always placed above Latin text. The positioning of text on signs is determined by the horizontal margins, as illustrated. A horizontal line separates the upper and lower portions of the sign face Text size To ensure legibility given the reading distances involved, potential speed of travel and the location of district signs, sign face text must comply with the size specifications on this page. Text sizes are the same for both single and double line district names For the smaller sign, the Alif height for Arabic text is 90mm and the x-height for Latin text is 60mm. The Alif height for the larger sign is 120mm and the x-height 80mm, as illustrated. The smaller sign has a margin of 120mm between the baseline of the Arabic text and the x-height of the Latin text, and the larger sign a margin of 160mm

64 District signs Colour border area 9.4 A dark red coloured border should be added around the sign face, following the chamfered corners as illustrated. The width of the border is 45mm for the smaller sign and 60mm for the larger sign. With the addition of the border, the final sign dimensions are 1,320mm x 1,000mm for the smaller sign, and 1,755mm x 1,320mm for the larger sign

65 District signs Colour border area 9.4 This page shows the coloured border applied to sign faces for the two sizes of district signs. Al Nahyan Sir Bani Yas Island

66 District signs Sign heights and locations 9.5 Location and clearance District signs should be placed at district boundaries in the Emirate, mounted on twin posts on the median strip of main arterial or sub-arterial routes facing the flow of traffic. The signs should be clearly visible during daytime and nighttime. For both sizes of district sign a minimum clearance of 2,200mm measured from the ground to the base of the sign is required, as illustrated. Where district boundaries are parallel with main arterial routes, district signs should be placed on the median strip at major intersections facing T-junctions or on roundabouts, alongside the flow of traffic instead of facing oncoming vehicles. For reasons of visibility, the larger sign is always preferred but the use of the smaller sign may be more appropriate depending on site-specific considerations. Should mounting on twin posts not be possible owing to circumstances on site, it is permissible to centre-mount the smaller district sign onto a lamppost

67 District signs Sign heights and locations 9.5 Double-sided signs Since district signs mark the boundary between one district and another, they are usually double sided. This page shows how each side of a district sign might look, including a side elevation illustrating the combined signs.

68 Municipality 10.0 identification pattern

69 Municipality identification pattern Post mounted signs 10.1 It has been proposed that some of the posts used to support street names sign should include a section of patterned fretwork. This would be achieved using two semi-circular rolled panels mounted to the post on ring collars. To provide some contrast to the matt aluminium post the fretwork panels can be manufactured in stainless steel. The pattern would be laser-cut before the panels are rolled to shape. The pattern used would be chosen by each municipality and initial designs have been prepared. These include traditional arabesque designs as illustrated. Art nouveau designs to match the sign designs already in use in Al Ain have been prepared as have a more abstract design that could be more suitable for Western Region Municipality. The size and proportions of the panels have yet to be finalised and a decision would need to be made as to which signs they are applied to. District name signs would be an obvious choice and perhaps the main street signs.

70 Municipality identification pattern Building address signs 10.1 Building address signs have a blank panel of dark red in the bottom half. This area can be used for the inclusion of additional address information such as a post code if this is developed. Until then it may be preferable to use the area for the application of a municipality identification pattern similar to the fretwork version used around the name sign posts. On building address signs the pattern will be printed at the same time as the rest of the sign graphics.

71 QR code placement 11.0

72 QR code placement Street signs 11.1 QR code labels should be affixed to signposts at a height of 1,400mm from the ground to the base of label as shown. The labels printed in black are 55mm x 55mm in size and required on every signpost fixed into the ground. All street signs will have a QR code which will allow the staff of government and private agencies, and the general public to access text stored in the QR code itself or to access a web site that provides extensive information either on the propriety or the street name

73 QR code placement Building address signs 11.2 QR code labels should be affixed to building address signs, located in the bottom right hand cormer of the upper dark blue section. The labels are printed in the dark blue colour with a white backkground and are 30mm x 30mm in size. This size allows them to align with the outer margins of the building address signs. QR codes are required on every building address sign. The QR codes provide information about the property location, address and postcode via a text page or website. In addition to being useful to residents the QR code provides information that can be used by utility services, government and private agencies who require additional information about an address. 30

74 Sign locations 12.0

75 Sign locations Sign positioning 12.1 There will be many restrictions on sign positioning on the ground. These restrictions will be determined by the general ground conditions, the existing groundworks with regard to paving and kerbs, and the location of utilities and services under the ground. 600 Physically there is also a requirement to ensure a certain amount of clearance from the edge of the road. Generally this clearance should be a minimum of 600mm from the kerb edge to the sign structure. This will provide a 'safe zone' which should protect the signs from strikes by wing mirrors on trucks and buses and any projecting loads on the back of lorries.

76 Sign locations Sign positioning 12.1 Any part of a sign structure, particularly any cantilevered sign panel should conform to the 600mm clearance requirement. 600

77 Sign locations Internal T-junction Option Internal street sign The illustration shows the preferred arrangement for internal street signs placed at the right hand corner of adjoining streets at T-junctions. Positioning internal street signs on the right at T-junctions assists approaching drivers identify the name of the street at that junction. The location also provides an equal reading time for vehicle drivers approaching from either direction on the cross street. Given the likely speed of travel and reading distances involved, the Alif height for Arabic text of 90mm should provide adequate legibility. Sign icons not to scale

78 Sign locations Internal T-junction Option Internal street sign This page shows an optional placement of internal street signs opposite the adjoining street junction. The arrangement is acceptable in situations where it is not possible to place the signs on the right hand corner of adjoining streets. Street signs in any location should not obstruct pedestrian flow along pavements. Sign icons not to scale

79 Sign locations Internal T-junction with island Option Internal street sign Internal street signs can be placed on a median divider island at the end of the street if one exists and there is sufficient space, or on the right hand corner of the street, as illustrated on the next page. The signs are double sided, post-mounted cantilevered signs positioned at right angles showing the names of both streets at a T-junction. Each sign aligns with the street to which the street name applies as a directional marker and aid to vehicle users. Sign icons not to scale

81 Sign locations Internal T-junction and cul-de-sac 12.3 Internal street sign Cul-de-sac sign A turning into a cul-de-sac from an internal street is signposted to be sufficiently visible to vehicle drivers from either direction. Cul-de-sac signs are double sided, post-mounted cantilevered signs positioned to point into the cul-de-sac as a directional marker and aid to vehicle users. Given the likely low speed of travel and reading distances involved, the Alif height for Arabic name text of 45mm should provide adequate legibility. More importantly the numeral size at 36mm is consistent with the size used on the internal street sign. Sign icons not to scale

82 Sign locations Main T-junction with narrow central reservation Option Internal street sign This page shows recommended sign locations at main T-junctions between two lane internal streets either side of a four lane internal street with a narrow median strip. In this instance internal street signs are placed on median divider islands at junctions to assist drivers approaching on the right. The signs are double sided, post-mounted cantilevered signs positioned at right angles showing the names of both streets at a T-junction, as illustrated in section Each sign points down the street to which the street name applies as a directional marker and aid to vehicle users. Given the likely speed of travel and reading distances involved across two lanes of traffic, the Alif height for Arabic text of 90mm should provide adequate legibility. Sign icons not to scale

83 Sign locations Main T-junction with narrow central reservation Option Internal street sign If there is no median divider island at a T-junction, internal street signs can be placed on the right hand corner of adjoining streets, as illustrated. Sign icons not to scale

In this instance internal street signs are placed on median divider islands at junctions to assist drivers approaching on the right. These signs are double sided, post-mounted cantilevered signs positioned to point down internal streets as a directional marker and aid to vehicle users. A larger main street sign is positioned on the median strip facing the centre of the junction as a directional aid for drivers entering the larger street. These signs are double sided and centre post-mounted. Given the likely speed of travel and reading distances involved along bigger streets, the Alif height for Arabic text of 120mm for main street signs should provide adequate legibility.

87 Sign locations Main T-junction with wide central reservation Option Main street sign Internal street sign The location of internal street signs at main T-junctions conforms to that set out in the previous section 12.3 option 3. In this instance where the main street has a wide median strip with features, such as trees and shrubs, obscuring the opposite side, two main street name signs are required, as illustrated. These signs are single sided and centre post-mounted, with a staggered position on the median strip relative to vehicle users approaching the main street on the right from adjoining streets. Given the likely speed of travel and reading distances involved along bigger streets, the Alif height for Arabic text of 120mm for main street signs should provide adequate legibility.

90 Sign locations Main T-intersection 12.6 Main street sign At large intersections, main street name signs should be used instead of internal street signs. Where main street signs aid the directional flow of traffic, they should be double sided, cantilevered signs positioned on the left or right pointing towards the relevant route. A double sided, centre post-mounted main street sign should be located on the left after busy intersections as a confirmatory marker to reassure vehicle users they are on the correct route. Given the likely speed of travel and reading distances involved along bigger streets, the Alif height for Arabic text of 120mm for main street signs should provide adequate legibility. Sign icons not to scale

91 Sign locations Rural T-junction Option Rural street sign Signs at junctions on smaller rural streets follow the general principle outlined for internal street signs in section 12.1, option 1 and are positioned on the right. Rural street signs are generally double sided, post-mounted cantilevered signs positioned at right angles showing the names of both streets at a T-junction. Each sign points down the street to which the street name applies as a directional marker and aid to vehicle users. Positioning rural street signs at the right at T-junctions assists approaching drivers identify the name of the street at that junction. Given the likely speed of travel and reading distances involved on these smaller streets, the Alif height for Arabic text of 45mm should provide adequate legibility. Sign icons not to scale

92 Sign locations Rural T-junction Option Rural street sign If rural street signs cannot be placed on the right hand corner at T-junctions, they can be positioned on the pavement opposite the road junction, as illustrated. Each of the cantilevered signs points down the street to which the street name applies as a directional marker and aid to vehicle users. Sign icons not to scale

93 Sign locations Rural T-junction Option Rural street sign Rural street signs can be affixed to property walls, as described in section 6.4, where they abut junctions. In this situation a single sided, centre post-mounted name sign should be positioned facing the centre of the junction to assist approaching vehicle users, as illustrated. Sign icons not to scale

94 Sign locations Main intersection Option Main street sign This page shows a main street intersection comprising two lanes of traffic in each direction. These main street signs are double sided, cantilevered signs positioned on the median strip facing drivers approaching on the right, pointing down the street to which the street name applies as a directional marker and aid to vehicle users. Given the likely speed of travel and reading distances involved along these bigger streets, the Alif height for Arabic text of 120mm for main street signs should provide adequate legibility.

96 Sign locations Main intersection Option Main street sign Overhead street sign This page shows a main street intersection with traffic lights, with streets comprising up to four lanes of traffic in each direction including slip routes. When required, overhead signs should be located at junctions controlled by traffic lights facing oncoming traffic, attached to the gantries above. These signs are usually double sided. Given the likely speed of travel and reading distances involved at main intersections, the Alif height for Arabic text of 150mm for overhead signs should provide adequate legibility. For slip routes at the right of the street not controlled by traffic lights, main streets signs should be located on an island on the right. These main street signs are double sided, cantilevered signs pointing down the street to which the street name applies as a directional marker and aid to vehicle users. Given the likely speed of travel and reading distances involved along slip routes, the Alif height for Arabic text of 120mm for main street signs should provide adequate legibility.

99 Sign locations Internal roundabout Option Internal street sign Internal street signs should be used at small roundabouts located on the right at roundabout exits facing oncoming traffic. The signs are double sided, postmounted cantilevered signs pointing down the street to which the street name applies as a directional marker and aid to vehicle users. Positioning internal street signs in this way assists approaching drivers identify the name of the street at that exit. Given the likely speed of travel and reading distances involved, the Alif height for Arabic text of 90mm should provide adequate legibility. Sign icons not to scale

100 Sign locations Internal roundabout Option Internal street sign Illustrated is an alternative option to the previous page with two double internal street signs placed at the opposite corners of the roundabout. Each of the signs is double sided and cantilever mounted onto a single post. The advantage of this arrangement is that only two signposts are required instead of four. Sign icons not to scale

101 Sign locations Main roundabout Option Main street sign Main street signs should be used for larger roundabouts, where routes comprising two lanes in each direction meet, located at the end of median strips at roundabout exits facing oncoming traffic. The signs are double sided, post-mounted cantilevered signs pointing down the street to which the street name applies as a directional marker and aid to vehicle users. Positioning internal street signs in this way assists approaching drivers identify the name of the street at that exit.

103 Sign locations Main roundabout Option Main street sign For roundabouts where routes comprising three or more lanes in each direction meet, a combination of main street signs on traffic islands and at the end of median strips is recommended, as illustrated. Vehicles turning right can follow the slip routes signposted at traffic islands and, if continuing straight ahead or turning left, navigate by the signs located at the end of median strips at roundabout exits. The main street signs are double sided, post-mounted cantilevered signs facing oncoming traffic, pointing down the street to which the street name applies as a directional marker and aid to vehicle users. Positioning main street signs in this way assists approaching drivers identify the name of the street at the various exits. Given the likely speed of travel and reading distances involved, whether using the slip route or negotiating the roundabout, the Alif height for Arabic text of 120mm should provide adequate legibility. Sign icons not to scale

104 Sign locations District name signs Option District sign District boundary District name signs are located primarily on main streets and indicate when a motorist has driven from one district into another. Where a district boundary cuts across a main street the positioning is simple - the signs are placed on the right hand side of the road, just beyond the boundary line and facing the approaching traffic. Where it would be impractical to position the sign on the right hand side of the road, the sign can be placed in the central median or central reservation running down the centre of the main street. If necessary this can be double-sided so traffic travelling in both directions can see the name of the district they are driving into. The majority of district boundaries appear to be placed along the centre of main streets and this can make locating the district name signs more difficult. At major cross-road intersections where the boundaries of four districts meet, the signs are placed just beyond the junction, on the right hand side of the road, facing the approaching traffic.

108 Sign locations District name signs Option District sign District boundary Generally, wherever a main street enters a district, a district name sign should be used. However it has been noticed that there are some small districts where there are no main streets entering them. In these situations a district name sign will need to be located on the primary internal streets that enter the district. Due to the smaller road size it may be more appropriate to use the smaller district name sign. This should still be located on the right hand side of the street, just beyond the junction with the main street and facing the approaching traffic. Sign icons not to scale

Using a code of just four characters (letters and numerals) the type of sign, the size of the sign, the fixing method and the sign configuration can be easily identified. Name signs are always the same depth depending on sign type. Their lengths are always multiples of the module length which is also determined by the sign type. The overall number of modules is of course dependent upon the length of the street name or the length of the district name. 7 modules 7 District / building address sign small S District / building address sign large L Sign fixing (third character) Centre post Twin post End post (cantilevered) Wall mounted Suspended Code C T E W S Sign faces (fourth character) Code Single 1 Double 2

111 Sign structure 14.0 and materials

112 Sign structure Signs on posts 14.1 Although some street name signs will be wall mounted, the majority will be mounted on posts in different configurations. At the beginning and end of open streets the name signs (with short names) will usually be cantilevered from a post. In this way the sign emphasises the start of the street and indicates the number range, and direction of numbering of the individual buildings. Longer street names will result in longer signs and these will need to be centre post mounted or twin post mounted if necessary. At intersections, the post can have a maximum of two signs cantilevered from them, usually at 90 degrees to each other and in line with the intersecting roads. If the junction has roads not intersecting at 90 degrees the signs can be rotated around to the appropriate angle. If a centre post mounted sign is used this will constitute two sign frames mounted either side of a post for each street name and so four sign frames can be mounted to one post if necessary. All signs are mounted at a minimum height of 2.2 meters above ground level to the bottom of the sign. Where two name signs are used on a post the lower sign is mounted at 2.2 meters and the upper sign mounted so the bottom of this sign clears the top of the lower sign with a distance of 40mm between them. Cul-de-sac signs will always be a single sign cantilevered from a post. This will point into the cul-de-sac and will primarily be indicating the number range of buildings in that particular section of the street. Cul-de-sac signs and Rural street signs are generally half the size (in height and length) of Internal street signs. Consequently they are more likely to be cantilevered from the posts.

113 Sign structure and materials Sign components 14.2 The majority of signs are fixed to vertical posts. The posts are hollow aluminium round tube and 90 mm in diameter. The sign frames are manufactured from aluminium extrusions, cut, formed and welded together. The outer frame profile is made using a specially designed extrusion and this is used for all signs regardless of type. To fix and position the signs on the posts two more specially designed aluminium extrusion are used as a collar around the posts. These collars are fixed in position using set-screws which lock onto the post. The collar extrusions are cut to length and machined as required. One type provides a cantilevered fixing to the end of the sign frames and the other provides a simpler design to fix sign frames in a centre-post mount arrangement. All aluminium used for extrusions for the signs should be of the grade 6061 or 6063 which will provide the corrosion protection required. All aluminium components should be hard anodised or receive a powder coat paint finish. Where required stainless steel fixings (nuts, bolts, threaded stud and screws) will be used as part of the sign assembly. All stainless steel used will be of the A4 grade to achieve maximum corrosion resistance and reduce electrolytic corrosion. To further reduce the effects of electrolytic corrosion junctions between stainless steel and aluminium should incorporate a non-conductive insulator. Note A full range of engineering drawings is available showing all components and fabrication detail. These are indicative in design and should be used to create prototype structures which can be tested before the final shop drawings are produced.

114 Sign structure and materials Sign components 14.2 Sign frames are proposed as a ladder structure and this will be prototyped and tested. The frame design provides a recessed flat area around the inner perimeter and on the vertical support sections. VHB tape is applied to these flat areas. The sign faces are made using printed sheets of 3M Diamond Grade reflective film which are laminated to a thin aluminium sheet. A clear protective film will be laminated to the printed surface of the Diamond Grade film. Sign collar 3M Diamond Grade reflective film The aluminium sheets are manufactured to a size that leaves 1mm clearance between each edge and the surrounding sign frame. This clearance will allow for any thermal expansion. The aluminium panels will be fixed to the sign frame using the VHB tape.

115 Sign structure and materials Ground fixing 14.3 For post mounted signs a substantial cast concrete base is required. The mass of each base can only be determined following a survey to assess soil and ground stability. Testing of base mass requirements should be carried out but it is recommended that a minimum mass of 400 kg. is used. The base will be concrete cast around a stainless steel ragbolt cage. The ragbolt cage structure includes four threaded studs projecting vertically from the top. These are used to bolt and adjust a fixing plate using nuts and washers above and below the plate to ensure the sign stands vertically. The fixing plate is made in stainless steel which is welded to a stainless steel tube. The diameter of the tube allows it to fit inside the aluminium sign post with a maximum of 1mm clearance around the circumference. The aluminium sign post is fixed to the steel post using recessed screws. Note A full range of engineering drawings is available showing all components and fabrication detail. These are indicative in design and should be used to create prototype structures which can be tested before the final shop drawings are produced.

116 Technical specifications 3M Diamond Grade reflective film 14.4 Sign faces will be lightweight, low cost and easily replaced panels made up from printed 3M DG3 film laminated onto a sheet of thin aluminium. This material is recommended for its reflective performance and consistency with other traffic control signs. The printing process developed by 3M is a digital printing operation that must be carried out on a particular model of printing machine and using inks specially formulated by 3M. There is a protective coating that is applied to the surface with provides more UV resistance as well as guarding against physical damage. If the sign faces are printed in this way on a single sheet of DG3 film which is applied in an approved manner to a sheet of aluminium substrate then 3M will supply a full warranty. Please note that the printing operation is achieved in a single-pass and all colours and graphics are therefore applied to the white version of the DG3 film.
