Infrastructure Development Code

DS-8.8 Design Criteria


  1. The following shall apply:
  2. The lighting design shall optimise the design spacing between luminaire positions by considering the combination of the mounting height, luminaire type, lumen output and luminaire wattage.
  3. For category P3 and P4 roads, one of the primary objectives is to reduce the luminaire power to less than 28 Watts per luminaire. Designs using luminaire power above 28 Watts will be considered provided this yields significant gains in the lighting column spacing.
  4. The lighting design shall minimise glare and light spill on neighbouring properties and the environment. Designs shall display horizontal illuminance isolines, including a 10 lux line.
    1. AS/NZS1158 provides requirements on the obtrusive effects of public lighting. 
    2. AS4282 provides further guidance.
    3. The maximum tilt for a luminaire shall be 0° for P Category and 5° for V Category (zero preferred) from the horizontal unless otherwise approved by Council.
    4. External screens shall not be used.
  5. For new designs on P Category roads, Council requires the luminous intensity at Gamma 80 to be limited to 400 cd and the peak intensity between 60° and 80° vertical at any horizontal angle to 1,800 cd.
  6. For designs on V Category roads, the Threshold Increment (TI) along the road shall be no greater than 12%, with the pedestrian traffic lights as well as the adjacent streetlights included in the calculation.
  7. The designer shall use the manufacturer’s data in conjunction with the NZTA M30 Specification to calculate Lumen Depreciation and to calculate the design Maintenance Factor (MF). 
  8. The designer shall also obtain the lighting manufacturer’s lumen maintenance calculation, based upon their proprietary method of determining lumen depreciation over 85,000 hours (energised time), 25⁰C ambient and 0.92 LMF (unless a more stringent factor is applicable), allowing for all electronic and optical degradation factors. The LMF factors provided in BS5489 may be used in lieu of those recommended in AS/NZS1158. The designer shall use the most conservative of the two maintenance factors for the design.

DS-8.8.1   Streetlighting Location

The following shall apply:

  1. Columns shall be located in accordance with AS/NZS1158. This shall apply equally to both V and P category roads unless specified below:
  2. For General Columns, set back from kerb face to the face of the column shall be:
    1. 1m unless otherwise noted
    2. 3m for roundabouts (for the extent of the illuminance calculation area defined by AS/NZS1158, but not less than 5m from the tangent point as defined in AS/NZS1158.1.2 clause B6.4 and figure B4) on V Category roads.
  3. For Frangible Columns (energy-absorbing or shear-base):
    1. If kerb present, same as b) above
    2. If no kerb present, distance from road edge (painted line or edge of seal) or:
      1. 1m behind a rigid barrier (e.g. concrete)
      2. Beyond the deflection zone of a non-rigid barrier (e.g. guard rail or wire rope)
      3. 3m minimum where there is no barrier
  4. For Rigid Columns:
    1. Where posted speed limit is 70kph or less, same as b) and c) above
    2. Where posted speed limit is greater than 70 kph:
      1. 6m from the road edge if there is no kerb and no barrier
      2.  As for sections same as b) and c) above otherwise
  5. Greater offsets may be required depending on the road classification e.g. for arterial roads it is desirable to have the columns located behind the footpath and to provide a longer outreach arm. For areas of high pedestrian usage, pedestrian specific lighting shall be considered.
  6. Joint Use Columns e.g. traffic signal & lighting, provide in accordance with traffic signal column requirement. Where possible streetlights at signalised intersections and pedestrian crossings shall be incorporated into joint use signal columns.
  7. In new subdivisions, columns shall be located:
    1. To provide the correct lighting levels in accordance with AS/NZS 1158 and the IDC.
    2.  Aligned with the road corridor boundary unless otherwise approved by Council.
    3. On designs prior to designing for the location of trees (to create the daytime aesthetics).
    4. Aligned with the common boundary between adjacent property lots, or
    5. Aligned off the build-line, i.e. the corner of a building within the property lot (this is particularly relevant with regards to point c below)
    6. Within 15m of the corner if it is the first lighting column in a side street. Measure from the property boundary facing the street that vehicle has turned from. The column shall be on the driver’s left side.
  8. Trees shall be positioned considering that the expected future dripline, when the tree is mature, will provide a minimum clearance of 2m from the dripline. 
  9. The expected future dripline of the trees when mature shall be shown on the lighting design layout. Consider the potential impact of shadows from road lighting when the trees are mature. Exercise care when selecting the species of trees and positioning them in relation to street lights.

Also consider the use of 6m columns in treed subdivisions. This will result in additional lights, but will better distribute light onto the road from under the tree canopy and limit spill light.

  1. Streetlight columns shall be clear of footpaths. 
  2. A streetlight shall be located within 10m on the approach side of the bus stop.
  3. Where it is required to locate a lighting column under an overhead low voltage power line:
    1. The designer shall utilise existing poles (where possible) by selecting lamps of appropriate luminance to provide the required standard of lighting to comply with the appropriate category (e.g. P1 to P3) under AS/NZS 1158. Consider supplementing the light from the other side of the road. Brackets on distribution poles shall comply with the requirements of the Utility Operator.
    2. There shall be a minimum of 1m clearance between the overhead conductor and the top of the lighting column at all times. Columns shall not exceed a height of 4 metres. The luminaire shall not protrude beyond the front face of the kerb. The maximum upward tilt shall not exceed 5⁰. For voltages greater than low voltage, ECP34 shall apply.
  4. Pole spacing’s shall be as per AS/NZS 1158. This may be varied where a proposed improved layout is approved by Council.
  5. Streetlights shall be positioned to be clear of trees. For mature tree-lined roads with trees on one side, columns shall be placed on the opposite side. If there are trees on both sides, columns on each side may be required, located midway between trees, with long outreach arms to reach out under the canopy. Pruning trees as part of the design is not recommended as this will be on-going and cannot be guaranteed.
  6. Columns shall be located outside the dripline and where the tree root structure cannot interfere with underground cabling or other underground services (unless tree pits are used to confine the root structure).
  7. Streetlights shall be positioned 1m clear of vehicle crossings. Safe sight lines for drivers exiting their properties shall be considered when locating streetlights.

DS-8.8.2   Lighting Columns

Drawing Reference: T801

The following shall apply:

  1. All columns shall comply with NZTA M26 and be supplemented by a PS1 Producer Statement.
  2. Shear base columns shall be used where the posted speed limit is ≥70 kph, unless the column is located behind a barrier, beyond the deflection zone.
  3. Where b) does not apply, Columns shall have a ground-planted base in residential and rural-residential areas unless otherwise approved by Council. They shall have a frangible base elsewhere.
  4. Each column shall be individually numbered at time of manufacture, together with the month and year of manufacture. In addition to the unique column number, a Quick Response (QR) code shall be attached for easy on-site data access. These labels shall be positioned above the gear door at a height of 2m above ground.
  5. All columns shall be hot-dip galvanised to prevent damage from the elements e.g. rusting etc. Galvanised columns may then be coated for aesthetic purposes before installation from the base of the column to 0.5m above final ground level using a two-pot epoxy paint or powder coating application approved by Council.

DS-   Column Height, Arm Length, Luminaire Mass and Sail Area

All columns shall be constructed as specified in Table 3: Standard Column Heights, Arm Lengths, Luminaire Mass and Sail Area below: 

Table 3: Standard Column Heights, Arm Lengths, Luminaire Mass and Sail Area

Nominal Column Height (m) Maximum Bracket Arm Outreach (m) Luminaire Mass (kg) Luminaire Sail area (m²)
14.0* 4.0 15.0 0.15
12.0 4.0 15.0 0.15
10.0 3.0 13.0 0.12
8.0 2.0 9.0 0.10
6.0* 1.0 8.0 0.10

* Appropriate for single outreach only.

  1. Standard columns shall have a curved outreach bracket arm with a 5° upward tilt.
  2. The minimum spigot diameter shall be 42mm.
  3. The minimum thickness of steel plate used in any structural column element shall be at least 2mm. Special requirements from AS/NZS 4676 apply if the thickness of steel used in any structural elements of the column is less than 3mm.

DS-   Wind Loading

The following shall apply:

  1. Columns shall be designed to safely sustain the appropriate loads as set out in the current version of AS/NZS 1170.2. Refer to Table 4: Factors to Determine Site Wind Speed.

Topographical Multiplier
  1. Wind loadings are assumed to be non-directional, i.e. the worst orientation of the column is considered. Designs that consider wind direction, with respect to the orientation of the lighting column, may be warranted in special cases, but this is generally not necessary.
  2. Wind pressures are based on design wind speeds for each wind zone as per Section 5 of AS/NZS 3604 and are calculated in accordance with AS/NZS 1170.2.
  3. The minimum drag coefficient is taken as for a smooth round shape (CD = 1.2). Other shapes will require modification with the appropriate modification factor in accordance with Table E4 of AS/NZS 4676.
  4. The frontal area of luminaires shall be taken from the orientation that results in the greatest wind exposed surface, and the force on these is assumed to act at the top of the column. The frontal area shall include all other attachments, motifs etc., which are not part of the main lighting column structure. 
  5. Allowance shall be made for the additional forces due to wind on a 1m² fixed sign; or for a single outreach, one 0.9m x 1.8m banner; and for a double outreach, two 0.9m x 1.8m banners, mounted 2.5m above ground level. Columns may be fitted with either a sign or banner(s), but not both.
  6. Column bases may require appendages to prevent twisting of the poles in extreme wind events. The following formula shall be used to calculate the pole loading due to wind speed. 

DS-   Minimum Column Strengths

Steel column strengths shall be based on the requirements of AS/NZS3404 and AS/NZS4600. Steel section strength requirements apply to the base of the column (at the top of the concrete footing), i.e. not necessarily at the ground surface. Minimum section modulus requirements shall take into account any service opening near the critical location at the base. Locations of openings other than at the base shall also be considered.

DS-   Deflection and Vibration

The complete assembly (e.g. column, outreach and luminaire) shall be designed to minimise deflection and vibration. To account for fatigue, the lateral liner deflection of the column shall not exceed hp/15, where hp is the height of a column above ground level.

DS-   Dynamic Response Check

The following shall apply:

  1. Translational Response:
    1. Dynamic response of a light column may subject the structure and fixtures to excessive acceleration and forces. Where structures have natural frequencies less than 1Hz, Section 6 of AS/NZS 1170.2 requires dynamic analysis to be carried out.
    2. The dynamic response of a light standard may be in a number of vibrational modes, including fundamental translational (lateral) cross-wind response as well as torsional response, particularly where the fixtures are eccentric and have high mass.
  2. Torsional Response:
    1. The torsional response may be combined with the translational response. As with the translational response, Section 6 of AS/NZS 1170.2 requires dynamic analysis to be carried out for structures with natural frequencies less than 1Hz.
  3. Wind-Sensitive Structure:    
    1. The dynamic analysis of a wind-sensitive structure is outside the scope of this document and specialist design will be required where the structure is deemed to be wind sensitive.

DS-   Switchboard (Door Cavity Opening)

The following shall apply:

  1. The door cavity opening shall be positioned to permit safe access for maintenance by:
    1. Not facing the street.
    2. The door cavity opening being accessible at all times.
  2. The door cavity opening shall be a standard size of 300mm x 150mm. The base of the door cavity opening shall be located between 600mm and 900mm above finished ground level, to provide safe and easy access for maintenance.
  3. The door cavity opening shall be prevented from being opened by unauthorised persons, by the use of fasteners requiring a specific tool to gain access to the switchboard.

DS-   Shear Base Columns

Shear base columns are only to be installed in speed zones of 70km/h or greater. All other speed zones shall utilise flange base or ground planted columns. All shear base type columns shall incorporate IP68 plug and socket connection to ensure that the pole disconnects from the live supply in the event of vehicle impact or similar occurrence (Transnet Amerace 65U or equivalent).

DS-   Foundation Design

Footings for lighting columns are classified into two broad groups:

  1. DS- Direct Planted Footings.
  2. DS- Pad Footings.

DS-   Direct Planted Footing

A direct planted footing is simply an extension of the pole. It relies primarily on varying the length of the extension (i.e. the embedment depth) and its projected area, to engage the required resistance of the foundation to overturning and sliding. This type is widely used for foundations with a bearing strength between 100kPa and 240kPa.

The embedment depth of directly planted poles shall be calculated in accordance AS/NZS 4676, taking due account of the mechanical properties of the particular foundation materials. The embedment depth should not be less than 500mm in any soil. The top 500mm of any pile foundation shall be ignored when determining capacity.

DS-   Pad Footing

Pad footings are usually constructed from concrete and rely primarily on their mass and the distribution of this mass to provide the required stability. For this type of footing, the embedment depth is not as critical a factor in the overturning resistance of the pole, but may be a major consideration in generating resistance to sliding. 
Base fixing bolts shall be designed in accordance with AS/NZS4676 and shall be arranged so that cable access through the base plate hole is not impaired.

DS-   Surface Coatings

The following shall apply:

  1. Surface finishes shall be smooth and free from obvious blemishes. 
  2. Final coating is optional. However, all columns, complete with mitred and curved outreach arms, shall be finished, both internally and externally, in one of the following forms:
    1. Hot dipped galvanised mild steel – painted, unpainted or powder coated
    2. Stainless steel (316 grade) – painted, unpainted or powder coated

DS-   Repair of Damage to Surfaces

The following shall apply:

  1. Corrosion protection that has been damaged by welding, erection or other causes shall be rectified before the column is put into use. The damaged area shall be prepared and shall be dry and clean, free from dirt, grease, loose or heavy scale of rust before the corrosion protection is applied.
  2. The corrosion protection shall be applied as soon as practicable and before noticeable oxidation of the cleaned surfaces occurs. Damaged zinc coating shall be restored by application of an equivalent thickness of a suitable zinc paint conforming with:
    1. AS/NZS 4680.
    2. AS/NZS 3750.9. 
    3. AS/NZS 3750.15 or with thermal zinc spray.

DS-   Contact with Ground Surface

Structural steel sections shall not make direct contact with the ground. All sections shall be embedded in or bear on concrete, or be otherwise protected. Concrete poured around steel structures shall be continuous and not cast in sections. 

All lighting columns shall, on top of the all-over galvanisation, be covered in an extra epoxy protective coating from 200mm above the ground level to the base of the column. Bare, untreated metal is not acceptable.

DS-   Warranty

The following shall apply:

  1. A copy of the coating applicator’s certification that the coating has been applied in accordance with the coating manufacturer’s specification shall be provided prior to the installation of the columns.
  2. If the applicator does not possess the necessary certified applicator status, the coating supplier shall monitor the work and provide the required certification.
  3. Materials and paint finishes of columns and luminaire bodies shall be unconditionally guaranteed against fair wear and tear for a minimum of 10 years, commencing from the date of handover to Council.

DS-   Welding

All welds and welding processes shall comply with the current standards outlined in AS/NZS1554

DS-   Quality Assurance Inspection

Council may elect to nominate an inspector to ensure the quality of the lighting column including, but not limited to the quality of the:

  1. Steel.
  2. Welding.
  3. Protective Coating. 

The manufacturer shall supply Council with all certifications to ensure the quality of the column.

DS-   Column Protection

The following shall apply:

  1. Structural members shall be adequately protected during handling and transport, to minimise damage to the corrosion protection. The columns shall be individually wrapped in heavy-duty polythene, or similar method of protection, to protect them from damage. The protective wrapping shall not remain in place for any extended period of time, e.g. during site storage, as damage to the paint finish is likely to occur.
  2. Components that are transported in nested bundles shall be separable without damage to other components or their coatings. Consider the use of lifting beams with appropriately spaced lifting points and slings, or lifting with properly spaced forklift tines.
  3. The column wrapping shall be applied while the column is installed and stood upright in the excavation, and the wrapping shall be removed upon completion of installation.
  4. Any damage caused before the handover to Council shall be repaired as new, with all warranties remaining intact. Where the damage is considered too severe, the contractor shall, upon written instruction from Council or its representative, replace the damaged equipment with a new item at no cost to Council.

DS-   Mowing strip

A smooth concrete mowing strip shall be provided around the base of lighting columns where appropriate. The concrete shall be 25MPa strength with a minimum width of 200mm on all sides and depth of 150mm. The concrete shall be boxed, finished level with the surrounding ground level and have a smooth trowel finish, slightly graded away from the column, to eliminate water collecting next to the column.

DS-8.8.3   Luminaires (Lanterns)

The following shall apply:

  1. All new or replacement luminaires shall be light-emitting diode (LED).
  2. All luminaires shall comply with the requirements of AM-8.3 Luminaires.

DS-8.8.4   Electrical Supply

The following shall apply:

  1. Each street light shall be connected directly to the distribution company reticulation. In some sections of road, it may be cost effective to connect more than one light to a single connection from the low-voltage network.
  2. The electricity reticulation supplying the streetlights is specified by the local network utility operator, which is the owner of the reticulation system.
  3. Design of the cables and switching shall be in accordance with the specifications and requirements of the local network utility operator and all new installations shall be underground.
  4. The Designer shall contact the local network utility operator for details of points of supply, switching and any other requirements and shall demonstrate to Council that this information has been obtained.
  5. The electrical power supply to the streetlights from the reticulation shall be owned by the local network utility operator.
  6. Where there is no established utility operator reticulation and many lights have to be supplied from a single network connection, install two separate cables with each cable looping into every second streetlight column. This means that, if a circuit fault occurs, only every second light will be out. This system is most used along long cycle routes. Cabling configuration shall be agreed with Council before design concludes.

DS-   Electrical Connection

The following shall apply:

  1. The number of lights connected to a single circuit shall be limited to four in any one direction from the supply point. Where more than one light is fed from a single distribution company connection, a 10mm² N/S single core cable shall be looped in and out of each column. Breach joints are not allowed as part of a new design. The boundary between the network company and the street light network is the load side of the fuse connected to the common LV network.
  2. Council is installing adaptive lighting in selected areas. This reduces spill light and sky glow, as well as energy consumption at times of reduced traffic volumes. The Central Management System (CMS) can be further extended through traffic sensors to be fully interactive, adjusting the light levels. In addition, allowance can be made for weather conditions. 
  3. At the base of each column, between 600-900mm above ground level, a fuse board shall be installed inside the column to meet the requirements of AS/NZS 3000 with a neutral and earth bar to comply with the requirements of an installation. A 6 amp type C HRC fuse link shall connect the light to the incoming supply. Miniature circuit breakers (MCBs) are not permitted.
  4. Slim columns approved for use on the network may use Transnet Amerace 65U in line fuse connectors (IP68) or equivalent. The neutral and earth bar arrangement shall still comply with AS/NZS3000.
  5. All shear base type columns shall incorporate IP68 plug and socket connections to ensure that the column disconnects from the live supply in the event of vehicle impact or similar occurrence (Transnet Amerace 65U or equivalent).
  6. In areas where a distribution company’s network is overhead and Council has installed luminaires on distribution company poles, each luminaire shall be connected directly to the distribution company supply using an HRC fuse in the live conductor. The fuse carrier shall be a 20 amp type. The HRC fuse link shall be 6 amps with fusing characteristic type C. Each luminaire along the street shall be connected to alternate phases to keep the load on the low-voltage network balanced. 
  7. Luminaires attached to utility operator poles shall comply with the utility operator standard procedures. 
  8. The boundary between the street light network and the network company is the load side of the fuse.
  9. Council is in the process of changing the control of all streetlights to a Central Management System (CMS). During the changeover, a mix of control types will co-exist. Council will advise the control type to be used in any particular area.
  10. The cable from the fuse board at the base of the column to the luminaire shall be two-core 2.5mm2 neutral screen. The screen shall be earthed. 
  11. Each column shall be earthed by means of 10mm² copper insulated wire, exothermically welded to a driven earth electrode (16mm diameter copper-bonded steel earth rod), located 300mm from the column base. Sherlock connectors are approved for burying. The connector shall be buried 300mm below the pavement surface. AS/NZS 3000 applies. 
  12. Where it is not possible to install a driven earth electrode due to rock for example, the following horizontal earth electrode is acceptable:
  13. A six metre (6m) length of 35 mm2 (19/16) bare (uninsulated) copper conductor buried to a depth of 600mm below the surface. The conductor shall be embedded in Bentonite slurry or Ground Enhancement Material (GEM). The buried conductor shall be placed with 3m either side of the lighting column. The horizontal earth electrode to column connection shall be the same as described above for the driven earth electrode.
  14. Each street light position is an installation as defined in AS/NZS 3000. All work shall be carried out in accordance with this standard, as well as Electricity (Safety) Regulations 2010 and the applicable electrical codes of practice
  15. Safe distance from electric lines and cables shall be maintained at all times. ECP 34 and the Safety Manual parts 2 and 3 Electrical Industry (SM-EI) set out the minimum approach distances for approved qualified staff with current Work Type Competencies (WTC).

DS-8.8.5   Decorative Lighting

Decorative lighting includes "up-lights", illuminated bollards and any other lighting not otherwise specified in the IDC but approved by Council. The following shall apply:

  1. Decorative lighting may be permitted in residential streets, minor roads and in some intermediate roads.
  2. Up-lights shall not present a tripping or slip hazard. 
  3. Internal anti-glare attachments shall be positioned to limit the upward light. 
  4. The construction and finish of bollard luminaires shall be consistent with the requirements for columns and luminaires. The maximum luminous intensity in any normal viewing direction shall not exceed 500cd/m².
  5. All luminaires shall comply with the requirements of AM-8.3.2 Decorative Luminaires.

DS-8.8.6   Traffic Signals

Refer to DS-4.9.5 Streetlight and Traffic Signals.
