Guide to the use of the paradigm (to writers of tender documents)In order to make it easier and faster for you to formulate tender documents, the Danish Road Directorate (DRD) has prepared tender paradigms, which must be used when inviting tenders for tasks from consult-ants and contractors.

The entire guide serves as a help to you and should of course be removed so that it does not appear in the finished document.

It is crucial that we describe our orders in detail so there is no doubt as to the delivery we want. When we base the tender documents on a uniform and recognisable structure, we make the entire procurement process easier for you as an employee of the DRD and for our suppliers.

The paradigms are changed on an ongoing basis in connection with new laws, executive orders and standards as well as the experience gained by the DRD, our wishes for rationalisation and much more.

THEREFORE, YOU MUST ALWAYS USE PARADIGMS WHEN PREPARING TENDER DOCUMENTS!

You CANNOT just find a previous tender document and "simply" adjust it as it may have become obsolete in the meantime. In order to make the writing process as easy as possible for you, the guide is part of the appearance of the paradigm itself. The meaning of the different colours, markings and brackets are as fol-lows:

Red text is a guide for you. It can be deleted when you are ready. The red text MUST be deleted no later than in connection with completion of the document.

Black text on a white background is standard text applicable to all contracts.As a general rule, this text should NOT be deleted or changed. However, you have to delete it, if a section or a text is not at all relevant for your tender.

Black text with a turquoise shading colour is text that should be adjusted to match the specific pro-ject.

The text should EITHER be included unchanged or removed OR be made more specific for the particular task – see the explanation below of the two types of brackets.

It is important that the turquoise shading is used for entire sections to facilitate the final editing. The shading must appear as one text block and not as in this sections where only the lines are shaded. If you only apply shading to single words or sentences, the guide to remov- ing shading colour does not work.

Make sure that you use the right turquoise colour by selecting the style "Turkis skyggefarve" (Turquoise shading) – or by selecting this specific colour:

The turquoise shading should be maintained until after you have read the document and be removed immediately before tender. Remove all shading in the entire document in one step by doing the follow-ing:

Ctrl+A (select all) -> tilted paint bucket (shading) -> select ”no colour”.

[A text block framed by square brackets] means that you only need to consider whether to include the text or not. As a general rule, the wording within the brackets should not be changed.

The square brackets should be maintained until after you have read the document and be removed immediately before tender. Remove all brackets in the entire document in one step by doing the follow-ing:

Ctrl+A (select all) -> Replace -> Find what [ -> replace with (blank field) -> Replace all

Ctrl+A (select all) -> Replace -> Find what ] -> replace with (blank field) -> Replace all

A text block <where part of the text is framed by angle brackets> means that you MUST insert a task-specific text here – for example a period of time.

The angle brackets are also used in Internet links and as a result, they cannot be removed as de-scribed above. They have to be removed individually.

If you need to add text not included in the paradigm, this text MUST be highlighted in yellow in draft tender documents.

In order to make the work as easy for you as possible and ensure that the finished document is without faults, you should proceed in this order:1. Read this guide every time, even if you think you remember its content. Consider printing it.

2. Make one document – SBB – for all documents.

3. Enable track changes in Word and set it so you do not see the changes but only the final docu-ment. The changes can always be made visible if you need it.

4. Delete the sections in the document that are not relevant for your tender.

5. Consider text with turquoise shading – either in [square] or <angle> brackets.

6. Add text if required. Mark it using yellow highlighting colour.

7. Delete red text when you are sure that you have understood the guide. You can make the text vis-ible again as long as you have not "accepted" the changes in Word.

8. Read the document carefully. Does it all make sense?

9. Do not proceed to item 9 UNTIL YOU AND THE DOCUMENT OWNER are sure that everything is correct and can be understood unambiguously by the supplier.

10. "Accept all changes" and remove the blue and yellow highlights and make all text black. Disable track changes.

The red table at the bottom of the page is used for document management, which takes place in several steps: In connection with the approval of a specific paradigm (e.g. Drainage), the form must be completed

by the paradigm owner.

Delete the form when you have prepared a project-specific document.

If you discover any errors in the paradigm or if you have any suggestions for improvements, please con-tact the unit or network responsible for the paradigm. Changes must be approved in accordance with the "Procedure for maintenance of tender paradigms".

SWS – Common to Design <contract number>

10 Street lighting

10.1 GeneralA project – for lighting of the below areas – is to be prepared. The exact boundaries of the areas shall be defined, considering the geometric detailed design and interfaces to the surroundings.

It shall be stated where you want the street lighting. The division into areas shall corres-pond to the requirements for lighting classes.

The final extent of lighting is determined by the contractor's consultant because there are interfaces to the existing lighting outside the scope of the contract and the geometric detailed design. The below specification of illuminated areas should therefore be able to accommodate adaptations to the surroundings and the geometry. Stationings are there-fore indicative. Alternatively, areas can be graphically illustrated on a drawing.

Area<motorway> <from Ch.> – <to Ch.>

<principal highway> <from Ch.> – <to Ch.>

<main road> <from Ch.> – <to Ch.>

<intersection> <Ch.>

10.2 Content of the projectGenerally, the project consists of three parts: project proposals, detailed project and ‘as built’ documentation. Each part consists of several activities of which some, in certain cases – depending on the scope and nature of the project – can be left out while others (e.g. light calculations) are iterative processes and therefore must be completed several times.

In the project, not all types of products mentioned – e.g. brackets and bridge mount brackets – are necessarily included.

The Employer shall do the handover inspection of the project proposal, detailed project and documentation. Any comments by the Employer on the project proposal shall be included in the detailed project. The work cannot be handed over until the documentation has been checked by the Employer.

10.3.2 Interchanges

In interchanges the slip roads and intersections are lit in cases where:

either the primary road (motorway or expressway) or the secondary road (the inter-secting main road) is lit

the intersection between slip road and the secondary road is signal-controlled

the intersection between slip road and the secondary road is a roundabout or rotary

there are complicated conditions on the secondary road with hatched road markings, bollards, turn lanes and the like.

At the intersection between slip road and secondary road, the columns are placed in ac-cordance with the same principles as with other signal-controlled intersections and round-abouts.

The section of the secondary road between the two lit intersections shall also be lit.

In cases where the primary road is not lit, lighting of the entrance slip road is established corresponding to the distance of 1-2 columns while the exit slip road is only lit by one column located right at the intersection. However, in partial cloverleaf / folded diamond type interchanges without separation between the entry slip road and the exit slip road, the lighting must be established along the entry slip road and past the separation point between the entrance slip road and the exit slip road.

of 21


In cases where the primary road is lit, lighting is established on the full extent of the entry and exit slip road.

Below are 4 types of intersections. The extent of the lighting is outlined, in cases where none of the roads are lit.

of 21


10.3.3 Shape of columns, brackets and columns

10.3.3.1 General

The selection of shape shall generally be uniform at a given road geometry and con-sidered relating to the surroundings including nearby or adjacent existing systems.

In cases where an installation is to be transferred to a municipality, instructions in the municipality's lighting plan or design manual shall be followed. See section 10.3.11 "Di-viding the lighting system".

10.3.3.2 Luminaires

Selection of shape may in many cases be limited by the required lighting performance, including available light distributions and lumen packages.

Below, possible shapes are described. You should generally select as many designs as possible or select "unspecified" so that the range of products is not limited.

Shape Description Geometry

Unspecified All shapes possible n/a

Hemisphere Housing shaped as a hemisphere.

Dome Housing shaped as an oval dome (an ellipsoid cut horizontally).

Boat Housing shaped as an ellipsoid cut horizontally and vertically ("a

boat turned upside down").

Disc Housing shaped as a section of a taper, cut with two parallel

planes perpendicular on the symmetry axis of the taper.

of 21


Wedge Ellipsoid cut with two planes. The lower plane should differ from

0º to +12º from the horizontal plane. The upper plane should

differ from -20º to the deviation from the horizontal plane of the

lower plane. Positive indication is clockwise.

10.3.3.3 Brackets

The recommendation of the luminaire manufacturer should as a rule be followed, as the luminaire in many cases is intended for a certain shape (and luminaire fixing angel and bracket projection) of the bracket.

The lighting design can be the determining factor for selection of shape, as a certain lu-minaire fixing angel and bracket projection may be required. See section 3.5 "Luminaire fixing angel and bracket projection”.

10.3.3.4 Columns

The recommendation of the luminaire manufacturer should as a rule be followed, as the luminaire in some cases is intended for a certain shape of the column.

The shape of columns shall be chosen within the framework stated in the table below. An "X" means that the shape may be employed.

The framework for selecting shape can be changed by deleting or adding some of the options in the following table.

10.3.4 Mounting of luminaires

Luminaires can be designed for post-top and/or side entry mounting. Mounting side entry on a bracket is based on at least one of the following:

the luminaire is designed exclusively for side entry mounting (typically the hemi-spheres, dome and cone shapes)

more than one luminaire per column

lighting design requires a bracket projection

lighting design requires a certain luminaire fixing angel.

In underpasses, luminaires can be designed for ceiling or wall mounting. It is preferable to mount in the ceiling for protection against vandalism.

10.3.5 Luminaire fixing angle and bracket projection

The shape of the bracket of the column is, for aesthetic reasons, determining for the up-per and lower limits for the luminaire fixing angle and bracket projection, to be chosen within the framework indicated in the following table.

Shape Bracket projection Luminaire fixing angleStraight bracket 0,1-0,5 m 0°

0,5-1,0 m 3°

Curved bracket 0,3-0,5 m 0°

10.3.6 Colour temperature and colour rendering

Luminous efficacy from LED packages increases with rising colour temperature. There-fore, for the sake of the energy efficiency of the system, you should aim at a choice of colour temperature as high as possible. However, warm-white light with a rather low col-our temperature has advantages regarding light quality, including colour rendering.

Where pedestrians and cyclists are present, there is a need to recognize faces and smal-ler objects. Here, you should choose warm-white light with a nominal colour temperature of 3000 K and a good colour rendering, Ra ≥ 80. This applies in most cases, for instance, to roads and intersections within urban areas, paths, car parks, carpool locations, road-side facilities, pedestrian crossings, shopping malls and at bus stops.

Where pedestrians and cyclists are not present, you should choose a neutral white light with a nominal colour temperature of 4000 K and a modest colour rendering, Ra ≥ 70. This applies in most cases, for instance, to motorways and highways as well as intersec-tions and roundabouts in rural areas.

10.3.7 Lighting control

In most cases, stand-alone time controlled dimming (self-adjusting timer unit) should be specified in all area types, except intersections, roundabouts, pedestrian crossings, speed reducing measures and at bus stops. Lighting control is typically specified at 50% of rated light flux between 22-06 hours.

Luminaires are supplied with a receptacle (Zhaga Book 18) for future control and monitor-ing with a compatible OLC (Outdoor Luminaire Controller) and an associated Central

of 21


Management System (CMS) system. Control and monitoring with an OLC will have prior-ity over stand-alone time controlled dimming.

10.3.8 Mounting and location of columns

The outer side of the column must have a distance to the asphalt edge of the road of at least 0.5 m and to the asphalt edge of a path of at least 0.3 m. The distance is recom-mended to be somewhat greater than the minimum requirements.

Columns (and foundations) must be placed appropriately in relation to the location of other objects, including road drainage (pipes, inspection chambers and ditches) and road equipment (traffic barriers and signs etc.)

The distance between the front of the column and the rear of the traffic barrier shall at least be equal to the deflection width of the traffic barrier, unless the column is rated passively safe. Columns must not be in line with traffic barrier poles.

Columns on bridges shall be mounted on a bridge mount bracket fastened to the edge beam of the bridge in accordance with ”Bridge Mount Bracket for Lighting Column on Bridge” (Danish Road Directorate’s construction drawing 25349). Bridge mount brackets may not be in line with traffic barrier poles. Columns mounted on brackets are usually located within the deflection width of the railing, regardless of its W-class.

10.3.9 Terrain category and reference wind speed

Terrain category is selected from the following table.

Terrain category

Description Picture

I Lakeshore and smooth flat country without signific-

ant vegetation and without obstacles as well as

coastal areas exposed to rough open sea.

II Farmland with boundary hedges and occasional

small farm structures, houses or trees etc. with a

distance of at least 20 times the height of the

structures.

III Suburban or industrial areas and permanent forest

etc. with a distance of no more than 20 times the

height of the structures

IV Urban areas in which at least 15 % of the surface

is covered with buildings and their average height

of 21


exceeds 15 m.

The default choice of terrain category is II. Terrain category 0 is not employed on land.

In areas in Jutland with locations less than 25 km from Vesterhavet and Ringkøbing Fjord, 27 m/s shall be selected as reference wind speed. In other areas, select 24 m/s.

10.3.10 Passively safe columns

On roads where the permitted speed is greater than 50 km/h, columns must be passively safe. The requirement does not apply if the columns are either placed:

behind the traffic barrier (outside the deflection width of the traffic barrier)

outside the safety zone of the road

or otherwise so that they cannot be hit.

The Speed class is dependent on the permitted speed and is to be chosen as stated in the table below:

Permitted speed Speed class50 - 80 km/h 70 km/h

50 - 130 km/h 100 km/h

The Energy absorption class is chosen based on several conditions. LE and HE-columns are used at the following places:

where there may be a danger that mislead vehicles can collide with dangerous obstacles such as trees, bridge columns or noise barriers

where a lot of walking and cycling traffic is present

in traffic islands and central reservations

and on bridges.

Other places NE, LE and HE are selected.

The safety class is chosen as high as possible, at least 2.

10.3.11 Sectioning the lighting system

If the Danish Road Directorate is the only Road Authority, please state:[All areas shall be managed by the Danish Road Directorate and thus, for administrative reasons, the lighting system shall not be divided.]

If not all areas are to be managed by Danish Road Directorate, please specify the road authority responsible for operation and maintenance of the lighting system. [The Danish Road Directorate and other road authorities shall – for administrative reas-ons – have separate meter points. The lighting system shall therefore be divided in such a way that service lateral, cabinet, street lighting cables etc. are separate for each road authority.

In the table below, the road authority is specified for each area.

of 21


Area Road authority

<motorway> <from Ch.> – <to Ch.> <road authority>

<principal highway> <from Ch.> – <to Ch.> <road authority>

<roadside facility> <Ch.> <road authority>

<bridge> <Ch.> <road authority>

<path underpass> <Ch.> <road authority>

<road underpass> <Ch.> <road authority> ]Electrical limitations as to levels of short-circuit current and voltage at the columns in the greatest possible distance to the street lighting cabinet may render a division necessary for the system.

Where the distance between neighbouring areas is sufficiently great, financially, it is more profitable to divide the system.

10.3.12 Location of street lighting cabinets

The location shall be:

appropriately in relation to the location of road drainage (pipes, inspection chambers and ditches) and road equipment (traffic barriers and signs etc.)

where a collision is most unlikely

with good accessibility and safety for future operating and maintenance works, includ-ing at least 0.8 m distance to other objects in front of the cabinet throughout its width

coordinated with the location of the junction cabinet (property of the distribution net-work operator) and cabinets for other road-related systems (fi. traffic signals, traffic counters, CCTV’s and pumping stations).

10.3.13 Ordering street lighting cabinets

Street lighting cabinets are the Employer’s own supplies. The Employer shall be informed of the details below for each lighting system. The information is necessary for the Em-ployer to be able to specify the street lighting cabinet and thus a precondition that Em-ployer’s own supplies can be carried out.

Type of meter (wires or plug pins)

Ikmin and Ikmax in the distribution panel (normally as specified in “Fællesregulativet”)

Number of groups, as 2 street lighting cables for each group

For each group:

o name of group (e.g. ”Columns in roundabouts”)

o the group cable’s number of conductors, cross section of conductors and mater-ial (e.g. 4·6 mm2 CU)

o size of the fuse per phase (e.g. 10 A)

o power consumption per phase.

10.4 Design base

10.4.1 Maintenance factors

The overall maintenance factor, f M is selected based on the following:

f M=f LF ∙ f LM

luminous flux factor,f LF. Is equal to 1,00 when light output is constant throughout life time (CLO)

luminaire maintenance factor,f LM . Determination is based on the assessment of the load level of particles and the assumption of a cleaning interval of 6 year. Default value of f LM= 0,90.
