DS-1.21 Putting it all Together 

PreviousNext

For each design there will be different parameters for the design rationale based on a range of variables such as the context, climatic conditions, ground conditions, site opportunities, density and constraints. As such, the weighting of the core design principles will also vary. The intention of DS-1 Putting it all Together is to ensure that each principle is considered as part of the design rationale and that the design reflects the best combination of these as appropriate to the site and desired outcome. 

DS-1.21.1 Positioning of Infrastructure within the Road Zone

Where activity related to DS-1.21 Putting It All Together is proposed for an existing Road Zone, these requirements shall be used in conjunction with DS-11 Road Zone Occupancy. For this situation, if any conflict arises between these sections, DS-11 Road Zone Occupancy shall take precedence.

Where the Road Zone does not exist at the time of design e.g. it is being designed and vested to Council ownership as part of a subdivision, Designers shall ensure that all components within the Road Zone are located considering:

  1. Potential for harm to people and property, relating to any component/s:
    1. At the time of installation.
    2. During its use i.e. operations, maintenance, connection.
    3. At the time of its replacement/renewal.
  2. Effects on all other installations within the Road Zone, whether:
    1. Already existing and in place.
    2. Installed at the same time.
    3. Proposed for future installation.

To ensure the above matters are provided for, Designers shall use the Utility Alignment Design Tool to select appropriate alignments within the Road Zone and use it as a guide for installations within Privateways, Right of Ways etc. For clarity, the use of the Utility Alignment Design Tool shall include the provision of all infrastructure, trees, gardens, furniture, structures and the like.

Where Council is not the future owner of the Road Zone e.g. NZTA, KiwiRail, the designer shall provide a copy of a written agreement from the future owner to demonstrate the design is acceptable to their requirements.

Explanatory Note:
As development intensification increases and evolves within Tauranga City, the pressures associated with servicing developments has become more difficult. Recent health & safety concerns, issues raised by industry co-stakeholders, the 2017 New Zealand fuel crisis caused by the striking of a major pipeline and difficulties experienced by all parties to resolve multi-asset clashes have shown this to be an issue requiring both a quick and longer-term response. 
This design tool was developed to respond to the concerns above as a temporary measure only. It will be updated or replaced by the outcomes derived from the IDC Transportation Provisions Project. This longer-term project will investigate this issue in more detail for a range of defined environments.

DS-1.21.2 Provision of a Utility Alignment Design Tool

Council developed the Utility Alignment Design Tool in collaboration with representatives from major Utility Operators from within the local area. The tool was developed considering the:

  1. Health and Safety at Work Act, with specific emphasis on s36-46 of the Act.
  2. Utilities Access Act and supporting documentation.
  3. Resource Management Act and the City Plan.
  4. Electricity Act and supporting documentation.
  5. Telecommunications Act and supporting documentation.
  6. Gas Act and supporting documentation.
  7. Health (Drinking Water) Amendment Act.
  8. IDC.

The Utility Alignment Design Tool shall be used to meet the requirements of the Health and Safety at Work Act as the intended primary empowerment legislation. Council determines that this Act shall be the lead requirement over any other Act for the provision of outcomes related to this multifaceted situation.

Explanatory note:
Emphasis has been placed on s36-46 of the Health and Safety at Work Act as these sections specifically cover:
Subpart 2 – Duties of PCBUs (a person conducting a business or undertaking)
s36 Primary duty of care
s37 Duty of PCBU who manages or controls workplace
s38 Duty of PCBU who manages or controls fixtures, fittings, or plant at workplaces
s39 Duty of PCBU who designs plant, substances, or structures
s40 Duty of PCBU who manufactures plant, substances, or structures
s41 Duty of PCBU who imports plant, substances, or structures
s42 Duty of PCBU who supplies plant, substances, or structures
s43 Duty of PCBU who installs, constructs, or commissions plant or structures
Subpart 3 – Duties of officers, workers and other persons
s44 Duty of officers
s45 Duties of workers
s46 Duties of other persons at workplace

Emphasis on the above sections of the Act does not negate any other section of the Act. Health and safety is of the highest priority to Council. Safety in design is a vital part of ensuring Designers produce designs that are considerate of the full lifecycle of the components / assets that make up any design outcome and activities associated with them during their lifecycle.

DS-1.21.3   Sizing Infrastructure

Prior to using the Utility Alignment Design Tool, the sizing of all infrastructure shall be completed as required by:
  1. The appropriate design section of the IDC.
  2. The design requirements of the Utility Operator for non-Council assets.
Explanatory note:
It is not the intention of the Utility Alignment Design Tool to define the size of infrastructure. The Utility Alignment Design Tool provides clarity on the location of infrastructure and whilst it may influence how a designer chooses to service a development, this is not its primary function or intention.

DS-1.21.4   Using the Utility Alignment Design Tool

Once the Designer has established the services required for the project and these have been sized using the appropriate design methods and calculations, the following steps shall apply:
  1. Select the appropriate Perspective Drawing cross-section for use as the template for the design outcome & selection of initial carriageway width.
  2. Position the utility mains (pipes, ducting and cables) within the alignment envelopes as provided. Ensure these are all located against the leading edge of the envelope. Refer to DS-1.21.6 Utility Alignment Design Tool for a definition of leading edge.
  3. Position the service connections. This shall be specifically designed considering:
    1. The effect of a connection failure on other services.
    2. The frequency of access to connections over the lifecycle of the utility. Where possible it is advisable that connections likely to be accessed more frequently are positioned shallower than other connections / mains where possible.
    3.  Agreed separation distances from other assets to reduce the possibility of harm to people and damage to other utility services. 
       
      Explanatory note:
      Service connection locations are not shown on the Utility Alignment Tool. This is because the final depth for each main is not confirmed until part b) above is undertaken. Different size and depth requirements for each design situation will result in differences in how and where connections are provided. As trends develop for certain situations, Council will update the Utility Alignment Tool to reflect better outcomes.
       
  4.  For any utility, where the alignment envelope space is not:
    1. Utilised in full.
    2. Identified for future use (as justified and supported in writing by the Utility Operator).
    3. Agreed separation distances from other assets to reduce the possibility of harm to people and damage to other utility services.  
  5. The minimum separation distances between the service mains shall be maintained unless a smaller separation distance has been negotiated and written agreement is provided at the time of application for Development Works Approval.
    Explanatory note:

    Alignment ‘banking’ by any Utility Operator will not be accepted by Council. As the future Road Zone land owner and Corridor Manager, Council reserves the right to decide whether protection of future alignment space is appropriate or not.

     
  6.   Position the structures e.g. cabinets, gyro boxes, access pits, manholes & the like
  7. Application for Development Works Approval shall not commence until one of the following has been undertaken:

    1. All components are located within the envelopes provided, envelope adjustments are completed as per d) above and all other information required by QA-3 Development Works Approval is completed.
    2. A negotiated outcome as per DS-1.21.5 Negotiated Outcome is completed and all other information required by QA-3 Development Works Approval is completed.

DS-1.21.4.1   Design Considerations 

Designers shall ensure that transition from existing infrastructure layouts / alignments are included as part of the design. In addition to the standard design requirements for each asset discipline, further considerations for designers include:
  1. Excavation
    1. Worksafe, under the regulations associated with Health and Safety at Work Act, require notification of excavations greater than 1.5m deep. 
    2. Utility Operators may require stand over attendance when working in close proximity to their services. Please liaise directly with the Utility Operators for advice on these circumstances.
  2. Energy (Power)
    1. Separation from the boundary is important to protect the infrastructure from private fence/wall/mailbox construction.
    2. Cables have a bend radius that requires space for the bend to occur.
    3. Cables can emit a heat radiance that can de-rate the current carrying capacity of the cables.
  3. Communications
    1. The envelope provided is to cater for all telecommunication ducting / cabling mains. 
    2. Preference for 450mm omnidirectional separation from high voltage power.
  4. Gas
    1. Where Gas is not proposed to be installed as part of a subdivision etc., this envelope shall remain in place for future service installation unless written confirmation is provided by the Gas Utility Operator that it is not required for future service installation. This confirmation shall be provided to Council when detailed design is provided.
  5. Water Supply
    1. The Water Supply infrastructure operates under pressure. This means that any damage to this can be a risk to other services.​
    2. The Water Supply and Wastewater separation distance is significant to reduce the chance of contamination to the Water Supply (for public safety). 
    3. Water supply pipelines require approximately 100mm under the pipe for the purpose of connecting fittings
    4. Where possible, typically where there is a wider berm, Water Supply shall located so it is not located under the footpath.
  6. Wastewater (option)
    1. The wastewater envelope shown is an option if the Designer can demonstrate that the pipeline can fit within this envelope.
    2. The envelope applies only to the pipe infrastructure.
    3. Designers shall ensure that the positioning and installation of manholes does not affect other services. 
    4. If fi)-iii) above do not apply, the Wastewater shall be positioned within the carriageway unless the Designer can provide for a design that positions it appropriately elsewhere. This requires a negotiated outcome as per DS-1.21.5 Negotiated Outcome.
  7. Trees / Gardens
    1. Species selection shall be made considering the available space, growing environment e.g. soil conditions and overshadowing of carriageways.
    2. Some species and soil conditions will result in shallow and wide root growth rather than deep and narrow. 
    3. Where the use of tree-pits or similar are approved for installation within the carriageway area, the Shared Zone envelope can be reduced to suit the requirements of the Streetlights and/or Street Sumps.
  8. Streetlights
    1. Streetlights shall be positioned as required by the Streetlight design and so not to damage other services or cause intrusion to sight lines.
    2. Details regarding the supply of power to each streetlight shall be provided with the design information.
  9. Sumps
    1. Sump selection and spacing shall not adversely affect shared zone services such as Trees and Streetlights.
  10. Pathways
    1. High pedestrian areas e.g. CBD, Commercial areas etc. generally require a wider or full berm width pathway where appropriate e.g CBD, Shopping Centres etc
  11. Stormwater
    1. Stormwater shall typically be positioned within the carriageway unless the designer can provide for a design that positions it within the berm. This requires a negotiated outcome as per DS-1.21.5 Negotiated Outcome where there is potential effect to other services.
  12. Carriageway
    1. The carriageway shall be sized using the requirements of DS-4 Transportation and T100 Perspective Drawings. Where appropriate to the design situation, the carriageway width may need widening to accommodate operations vehicles, safe manoeuvrability e.g. considering topographic influence on the geometry of the carriageway layout.
    2. Subsoil drains shall be provided where required by DS-4 Transportation.
    3. Parking shall be provided for where required by DS-4 Transportation.
  13. Structures / Street Furniture
    1. The provision of large structures that may affect underground services or above ground activity e.g. sight lines, require a negotiated outcome as per DS-1.21.5 Negotiated Outcome.
  14. Retaining Walls
    1. Where a retaining wall is proposed within or adjacent to the Road Zone, the provision and location of utility services shall be included as a part of the design philosophy for the retaining wall. 
    2. The presence of a retaining wall requires a negotiated outcome as per DS-1.21.5 Negotiated Outcome to confirm all constraints and outcomes.
  15. Connections
    1. Designers shall ensure that the positioning of connections to/from underground services considers the positioning of other underground services and reduces, as much as is practically possible, future risks to workers or other services and connections. 
Explanatory note:
These design considerations are provided to help designers to undertake an appropriate level of due diligence however, they are not exclusive. Where unclear, or where other issues arise, designers shall communicate and collaborate with all affected parties to achieve the best possible outcome considering all issues.
In turn, all affected parties are expected to communicate and share information to help achieve good collaborative outcomes.
 

DS-1.21.5   Negotiated Outcome 

The following shall apply:
  1. Where any of the following conditions exist, a negotiated outcome is required:
    1. Proposed pipes, ducting, cables do not fit within the appropriate utility envelope.
    2. Service chambers/pits encroach within any envelope.
    3. A retaining wall is present or proposed to be located on either side of the Road Zone boundary.
    4. Positioning of street furniture.
    5. Larger separation distances are required, typically for larger main sizes.
  2. A negotiated outcome involves a discussion & agreement between all affected parties. It shall be facilitated by the designer. This discussion shall also include:
    1. A Council Development Engineer where related to development works.
    2. A Council Project Manager where related to Council project works. 
  3. Where agreement between parties cannot be obtained, the resolution decision shall escalate to an adjudicator appointed by Council, who will consider all opinions and make the decision in order to move the issue and therefore, the project, forward. Escalation issues shall be referred to Councils Manager: Asset Planning and Information.

The negotiated outcome process shall be completed, along with the final agreed design, prior to Development Works Approval application.

Explanatory note:
Council will manage the situation where co-stakeholders cannot agree on the outcome for proposed Council owned Road Zones. Council is assigned this role because Council will become the owner of the Road Zone & therefore has responsibilities to manage activities associated with the Road Zone after it is vested to Council ownership. 
Where the associated Perspective Drawing cross-section requires a wider berm e.g. collector, arterial roads, or larger sized mains are required, larger separation distances may be required. These shall be agreed & confirmed as per DS-1.21.5 Negotiated Outcome.
 

DS-1.21.6 Utility Alignment Design Tool

The Utility Alignment Design Tool is show below:

Trailing edge of Water Supply Utility Leading Edge of Wastewater Envelope 1000

Where the associated Perspective Drawing cross-section requires a wider berm e.g. collector, arterial roads, or larger sized mains are required, larger separation distances may be required. These shall be agreed & confirmed as per DS-1.21.5 Negotiated Outcome.

Explanatory note:
The Leading Edge is the edge of the utility envelope that is closest to the property boundary. All utility pipes/ducts/cables shall be aligned against the Leading Edge of the envelope. The Trailing Edge is the point of the actual pipe/duct/cable that is furthest from the property boundary. The separation distance is measured from the trailing edge of one service, to the leading edge of the next service.
 

DS-1.21.7   Example of How to Use the Design Tool

Explanatory note:
The example above is indicative only. Its purpose is to show designers how to use the tool and trim the excess unused design envelope. It assumes the placement of the Stormwater is in the centre of the driving lane within the carriageway. 
Although the Water Supply Ridermain is smaller than the main, it is not practical to alter the berm size where the Ridermain is located.
