Design resubmissions

Any non-compliance or defects not already agreed with Council will result in the design being returned to the consultant for rectification. These issues include:

• the design does not meet the requirements of City Plan
• calculations showing incorrect design or incorrect design files used or luminaire i-table not compatible with nominated poles
• incorrect calculations provided - wrong i-table, incorrect parameters used
• not including obtrusive lighting results
• over-lighting, where smaller and or less luminaires are able to achieve the required outcome.
• excessive amounts of spill light, non-compliant with AS/NZS 4282
• electrical design non-compliant with AS/NZS 3000, where applicable.

Where the above are not achievable the design consultant shall engage with Council to reach agreement on the preferred solution.

It is expected that if the design consultant finds themselves having issues with the existing luminaires adjoining a particular development, the design consultant shall consult with Council to provide a way forward.

The type of design determines the qualifications required for lighting designers, listed below.

Energy Queensland/Energex street lighting Rate 2 requirements:

• Registered Professional Engineer Queensland (RPEQ) – Electrical (with demonstrated experience in preparing road lighting design)

AND

• Working for an Energex accredited consultancy firm

Pedestrian Rate 3, metered or under-awning lighting requirements:

• Registered Professional Engineer Queensland (RPEQ) – Electrical (with demonstrated experience in preparing lighting and electrical designs)

OR

• A member of the Illuminating Engineering Society of Australia and New Zealand with minimum grade of “Member”.

Electrical components/reticulation for any lighting design requirements must be certified by a Registered Professional Engineer Queensland (RPEQ) – Electrical.

The following list contains general guidance for lighting consultants on the expected information and design factors to be considered when designing Rate 2 and Rate 3 lighting.

• Request for street lighting parameters if requirements not in the DA or confirmation of street lighting parameters if requirements are included in the DA. DA conditions to be included with street lighting parameters request.
• If the lighting consultant believes the design parameters nominated do not suit the installation and/or site conditions, the consultant is requested to raise this with City Lighting.
• All new lighting and all relocated lighting is to be LED.
• It is the lighting consultant’s responsibility to engage with Energex to ensure that the supply is available and accessible for public lighting. 
• Non-compliances with AS/NZS 4282 to be raised and acceptance confirmed by City Lighting before submission and documented in the compliance certificate.
• No more than two poles located adjacent to the one property street frontage up to 4m past each of the property boundary locations. This should be minimised as far as practicable to limit spill light issues.
• Pole heights to be minimised and consistent.
• Consistent spacings to be used as far as practicable. Spacings should not vary by more than 20% in a continuous run of spans.
• Lighting not to be spaced less than S/2 (maximum spacing divided 2), unless otherwise unavoidable. This shall be agreed with City Lighting prior to submission.
• The lighting power consumption shall be minimised. 
• The number of luminaires required to provide a compliant design is to be minimised.
• In subdivisions it is expected that if a project is extending or modifying the current lighting arrangement that the dominant luminaire style in the subdivision will be used for the modifications, this may require additional columns and luminaires to be installed for compliance. Where Energex standard products are no longer available, contact City Lighting for advice on suitable poles and luminaires.
• For P and V category designs, the minimum spacing is to be used when interfacing with different arrangements, lamp types/wattages, etc.
• The use of the 10% allowance for spacing is to be confirmed with City Lighting before it is adopted in a design.
• Where Pedestrian lighting and lighting installed in the building’s awning are to be integrated, both submissions are required to evaluate the interaction.
• Poles on roads without kerbs are to be located a minimum of 3m behind the lane edge line.
• Lighting shall not be removed for accessible roads or footpaths until temporary lighting, or the final design lighting has been installed to suit the installation.
• It is preferable for a street light to be installed on the approach side and close to a bus stop location.

The following guidance is provided for V category roadway lighting installations:

• For ‘V5’ roads the preferred mounting height is 9m.
• For ‘V3’ roads the preferred mounting height is 10.5m.
• Spacing calculations are to provide sufficient detail in regard to the span or spans that they are referring to such as reference to station numbers, chainages, etc.
• For ‘V5’ roads the maximum luminaire wattage is to be 90W LED (2021) luminaire or equivalent as LED technology advances.
• For ‘V5’ roads it is expected that generally the L50 LED luminaire will be sufficient.
• 0° upcast shall be used on all designs. Where it is found that a 5° upcast will reduce the number of columns and luminaires required, City Lighting is to be consulted and must agree prior to design submission.
• All values as required by the relevant part of AS/NZS 1158 series to be supplied. This includes illumination design areas for V category areas as well as the surrounding areas where applicable. 
• Consistent luminaire wattage should be used for the design. It is expected that an L170 would not be placed in a run of L50 luminaires.
• The resultant design shall not achieve a lighting outcome that is higher than 1 sub-category above the required lighting sub-category for any span.
• Where minor non-compliances are found, discussion with City Lighting may allow the non-compliances in the lighting design to minimise other potential issues.
• It is expected that the design consultant will achieve luminance requirements on the through carriageways at intersections as per AS/NZS 1158.
• All illuminance design areas shall be outlined, and the illuminance levels supplied shall be in accordance with the requirements of AS/NZS 1158 series. This includes illuminance levels and uniformity for surround areas.
• If a luminaire adjacent to an intersection is amended in any way the lighting of the intersection shall be evaluated and results of the evaluation provided, including where the designer attempts to exclude the intersection for the LOR (limit of responsibility).
• AS/NZS 4282 compliance to be submitted.

The following guidance is provided for ‘P’ category roadway lighting installations:

• Council City Plan amendment to AS/NZS 1158.3.1 are to be used in the design.
• For situations where lighting is required as per clause 4.3.2 (b) of AS/NZS 1158.3.1, an L50 or equivalent new LED product shall be used at a mounting height of 7.5m maximum to achieve the required light level over the nose(s) of the island. Standard 4.5m outreach or 5m special outreach. These measures are to minimise spill light to residents.
• 0° upcast shall be used on all designs. Where it is found that a 5° upcast will reduce the number of columns and luminaires required this is to be discussed and agreed with City Lighting prior to design submission.
• Preferable mounting height of 7.5m for steel poles. Preferable mounting height of 5.1m for estate poles.
• Consistent luminaire wattage should be used for the design.
• Luminaires to be spaced at no more than 65m, unless agreed with City Lighting prior to design submission.
• The resultant design shall not achieve a lighting outcome that is higher than 1 sub-category above the required lighting sub-category for any span.
• Where minor non-compliances are found, discussion with City Lighting may allow the non-compliances in the lighting design to minimise other potential issues.
• There should be no more than 2 poles located adjacent to the one property street frontage up to 4m past each of the property boundary locations
• ‘V’ category lighting designed for installation in ‘P’ category road where required at the intersections of ‘V’ and P category roads is to be mounted no higher than 7.5m
• Lighting not to be spaced at S/2 or less, unless otherwise unavoidable.
• AS/NZS 4282 compliance to be submitted.

Designs with tight bends

This diagram is included to assist designers in interpreting the text in the Council City Plan 2014 for tight bends which can also be applied to intersections for 'P' category roads.

• This still requires that the spans are calculated to show that the minimum required LTPs are still met. 
• The span is light to light, not just the curve itself, this is to ensure that the entire curve is compliant and that each span also remains compliant as required by AS/|NZS 1158.3.1.  This may require multiple calculation areas if the curve is greater than one span.

Designs including LATM devices

This diagram shows requirements for a Local Area Traffic Management (LATM) device where the kerb itself is modified, and the preferred location of the luminaire in this instance. 

• Note the pole setback from the projected kerb. 
• Other factors and requirements are to be taken into account when placing the pole.

• If the area is not classified as an LATM device, it is preferred that a luminaire is installed at the location indicated and located at the standard setback from the projected kerb line. 

The following guidance is provided for Pedestrian, Parks and Metered lighting installations:

• Council standard drawings are to be complied with, except where specifically instructed.
• Council, Department of Transport and Main Roads or Energex standard equipment to be used, as applicable. Discuss with City Lighting early in the design process to minimise the possibility of redesign work.
• 0° upcast shall be used on all designs.  Where it is found that a 5° upcast will reduce the number of columns and luminaires required this is to be discussed and agreed with City Lighting prior to design submission.
• All pole mounted luminaires shall be fitted with a 7 pin NEMA receptacle and 3 pin NEMA PE Cell or blanking cap as applicable to the design.
• For Council owned and/or maintained installations Earth Fault Loop requirements shall be met before the inclusion of the RCD/RCBO in the design.
• All electrical calculations are to be submitted with the design, including voltage drop and fault loop calculations. Sufficient information is to be provided to allow for the calculations to be checked. Fault Loop Impedance calculations are to include all components including the transformer and all downstream components. Calculations shall be provided for each metallic enclosure, switchboard, pole, luminaire, etc. The calculation to the last pole/luminaire on each circuit is sufficient.
• All cabling is to be a minimum of 16mm² with reticulated earth where required unless agreed otherwise with City Lighting.
• There should be no more than 2 poles located adjacent to the one property street frontage up to 4m past each of the property boundary locations.
• Designs are to include schedules for luminaires, conduits, and cables.
• Schedules should closely resemble those in Energy Queensland Limited (EQL) designs and be included in design documentation.  These will be slightly different unless specific EQL-approved items are to be used.
• Site IDs are to be included on the design drawings. Site IDs are available from City Lighting for metered, solar, and unmetered Tariff 91 installations.
• Lighting not to be spaced at S/2 or less, unless otherwise unavoidable.
• For DA specified ‘Pedestrian Lighting’ the Council City Signature poles and iGuzzini V949 BCC Special 9W luminaires are to be used.
• Designs shall show that the vertical calculation points at curves or corners in a pathway continue to be provided with compliant lighting levels.
• City Lighting is to be contacted to undertake an inspection of the installation prior to the installation being given ‘On Maintenance’ status.  City Lighting will then provide an email that the DA condition is satisfied for the ‘On Maintenance’ requirement.  When contacting City Lighting for this requirement supply the following documentation:
  • As Built Drawings.
  • Electrical Test results for the installation. The results for EFLI shall show compliance for EFLI for the size and type of the protective device not allowing for the RCBO/RCD.
• The design shall be compliant with AS/NZS 3000.
• AS/NZS 4282 compliance to be submitted.

Tree/vegetation near lighting requirements in Council City Plan 2014

Lighting consultants must be aware of City Plan requirements regarding trees and vegetation near lights.

Refer to City Plan 2014 Schedule 6, SC6.16, Chapter 3 Clause 3.7.7.5 e. text included below.

1. Unless specified otherwise in this chapter, the design and installation of pedestrian lighting meet the following requirements:

"e. to be located below the tree canopy of existing trees or sufficiently separated from existing or proposed vegetation so the vegetation does not obstruct light reaching the area intended to be illuminated. Council's preference is to have a clear trunk of a minimum height of 3m at maturity where located within 7m of a pedestrian light.”

On and off maintenance requirements

These requirements are only applicable where Council is the owner/maintainer of the installation such as pedestrian lighting.

On maintenance

The developer must contact Council’s City Lighting team to arrange a commissioning/on maintenance date for the lighting/electrical after the defects and non-compliance issues identified in the pre-commissioning audit report have been rectified.

Prior to the pre-commissioning audit, the developer is to supply the ‘As Built’ drawings, electrical test certificates, installation certification, etc.

Final inspection/compliance inspection shall be carried out by an appointed Council’s Electrical Compliance Officer and/or a Council Development Assessment engineer. If satisfactory, Practical Completion will be granted which will initiate the defects liability period.

Off maintenance

The developer shall contact Council to arrange an off-maintenance inspection. Any defects identified shall be rectified at no cost to Council.

Under awning lighting designs

The following guidance is provided for under awning lighting designs:

• Lighting is to be designed in accordance with lighting technical parameters (LTP) for lighting category PA1 for footpaths.
• The lighting installed under the awning is to light the area of the footpath under the awning plus an additional 2m toward the kerb to the required lighting sub-category.
• Any remaining area from 2m out from the awning toward the kerb can be lit to the requirements of lighting category PP3.
• Under-awning lighting submissions shall clearly show the point horizontal illuminance values and vertical illuminance values for both directions on separate layouts to allow compliance to be readily assessed. LTP results are to be summarised in a table for each design area.
• Under-awning lighting submissions shall state on the drawings the following:
  • The lighting is to be operated from dusk to dawn.
  • Lighting is not to be operated by a time clock.
  • PE cell control only shall be used.
  • Lighting is to be owned and maintained by the building owner.
  • Lighting is to be maintained in good working order.

Temporary lighting designs

If a development removes the existing public lighting, the developer must provide temporary lighting until the permanent lighting is reinstalled.

• Temporary lighting designs are to be submitted as per a standard design submission for acceptance.
• Temporary lighting must be accepted by City Lighting and installed prior to the removal of any existing lighting.
• The temporary lighting submission is to be accompanied by the proposed permanent lighting design for installation at the end of the requirement for temporary lighting.  
• The proposed permanent lighting is to be installed and operational prior to the decommissioning of the temporary lighting.
• Temporary lighting is to be installed to any publicly accessible area where the existing lighting is to be removed for any period of time.

In addition, the following items could be applicable:

• If external temporary lighting is used, glare to motorists and residents must be considered.
• Flood lights are not acceptable for road lighting.
• Noise produced by any generators used must be considered.
• Temporary solar lighting must have a 5 day autonomy (days without generation).
• Existing public lighting cannot be energised by the development site's power.
• Confirm the timing/dates of Energex/accredited contractor will be carrying out the works.
