9.1 Introduction Replaces (ITS Section 1, Clause 1.1.2)

This volume has been prepared as a supplement to the Hamilton City Infrastructure Technical Specifications (ITS) for use by the Waikato District Council.

This section sets out general variances to the Infrastructure Technical Specifications and/or additional design standards or technical specifications that should be followed for the installation of services in subdivision and contract works in the District Council area.

Where there is any discrepancy between this section and the council’s District Plan, then the District Plan shall have precedence.

Any ambiguities between documents should be addressed in the first instance by referring to the hierarchy below, and then by contacting the District Council directly if uncertainty remains.

Where possible, reference to the original Hamilton ITS clause that has been amended or added to is given in the appropriate location in bracketed italics. Where there is no reference this is either a new requirement not alluded to in the Hamilton ITS, or the requirements are spread over several non-sequential sections or clauses which makes it difficult to reference.

9.2 General

9.2.1 Defects Liability (ITS Section 1, Clause 1.7.2.3)

The Defects Liability Period for sub divisional works shall be 12 months.

9.2.2 Temporary Traffic Management (ITS Section 1, Clause 1.10.3)

As for the Hamilton ITS, except Level 1 Traffic Management will always be acceptable on WDC managed roads of Level 1 or lower; no higher requirement will be insisted upon unless that road has been designated a higher level.

9.2.3 Drainlayers All services are to be installed under the supervision of a registered drainlayer or a suitable reticulation service person approved by Council.

9.2.4 As-Built Records Generally as per Hamilton ITS requirements, plus the following sections have their own requirements:



9.3 Earthworks and Geotechnical Requirements No amendments or additions required.



9.4 Transportation

9.4.1 Application This section sets out the general roading standards for the design of subdivisional roads in the District Council area.

9.4.2 References (ITS Section 3, Clause 3.2.1)

Additional design reference documents:

• “Rural Road Design - A Guide to the Geometric Design of Rural Roads” - Austroads (AP-G1/03) • “Intersections at Grade” - Austroads Guide to Traffic Engineering Practice – Part 5 (AP-G11.5/05)

9.4.3 Road Names The Council, wherever possible, will seek to use road names as a way of recognising significant history of an area. Some Community Boards and Committees have developed a list of “Approved Road Names” for naming new roads in their community. Where these exist, the developer shall choose from that list or submit a written request to use other names, including the reasons why they want that name or names to be used.

Refer to Council’s Road Naming Policy on Council’s website for further details.

Council will arrange any necessary authority for the regulatory signage and marking. All costs associated with the gazetting and implementation of the traffic services are to be paid by the consent holder.

9.4.4 Road Classification HCC’s Criteria for the form of Transport Corridors (ITS Section 3, Appendix A) has been replaced for the District Council by Appendix A of this document.

9.4.5 Geometric Standards Typical cross section requirements relating to Waikato District Council are shown on the Road Classification Table in Appendix A, or the District Plan.

Turning heads will be required at the end of all no-exit roads in accordance with Austroads Rural Road Design.

9.4.6 Geometric Design Geometric design, including gradients, super elevation and road widening shall generally be in accordance with the Austroads publication “Guide to Geometric Design for Rural Roads” except for the following points:

9.4.6.1 Crossfall

(ITS Section 3 Clause 3.2.2.3)

Normal crossfall in rural areas may be -3.0% or -4.0% at the designers discretion.



9.4.6.2 Super-elevation


Super-elevation shall not normally be required on curves in rural/residential subdivisions.

Where it is required, super elevation design shall generally be carried out using Austroads Guide to Rural Road Design. See Road Classification Table in Appendix A for maximum super-elevation at intersections.

9.4.6.3 Longitudinal Gradients


Where Kerb and Channel is not required or proposed, there is no minimum longitudinal gradient on the road.

9.4.6.4 Turning Heads


The maximum longitudinal, or cross sectional slope in turning heads is 6.0%, with the desirable matching normal camber.

9.4.7 Walkways (ITS Section 3, Clause 3.2.16)

Rural residential subdivisions should make provision for pedestrian access along grass berms. Refer to the District Plan, or Appendix A of this document.

9.4.8 Road Reserves and Fencing (ITS Section 3, Clause 3.2.1 to 3.2.8)

Adequate width of road reserve is important and is normally 20 metres. Increased width is likely to be required where earthworks are extensive. A minimum clearance of 3 m is required between the road reserve boundary and tops of cuttings or toes of embankments.

All road reserve boundaries shall be fenced before the 224 certificate will be authorised, unless written permission to do otherwise has been received from the District Council.

9.4.9 Pavement Design 9.4.9.1 Subgrade Improvement Layer (Blue/Brown Rock)

Further to (ITS Section 3, Clause 3.3.2.3), the following requirements shall also apply for the application of blue/brown rock:

In some places, the blue/brown rock material needs to be tapered to thicknesses less than the materials maximum size. Therefore an AP40 material may be used in the finishing of this sub-base layer to ensure that this can be achieved.

The construction shall comply with NZTA B/2, however the Contractor shall carry out the compaction testing (may need to break up larger particles to perform the compaction curve and CBR test to replicate field conditions). The Contractor shall confirm that the target density will consistently satisfy the minimum CBR requirement



9.4.9.2 Sealed Pavements

Pavement design shall be in accordance with the ITS (Section 3, Clause 3.2.12), except:

1. The percentage HCV’s shall be 9%

2. Basecourse aggregates for unbound pavement shall be NZTA M/4 only

9.4.9.3 Unsealed Pavements

Unsealed pavements shall be compacted with a minimum compacted thickness of 300mm of well graded granular material with a minimum soaked CBR of 20. The maximum particle size shall be no greater than 100mm. This pavement material shall have sufficient fines to ensure that it does not unravel under the action of traffic. A material typically used on Waikato District Council unsealed roads is a high grade brown rock but will vary depending on locality. A 50mm minimum compacted thickness wearing course shall then be constructed using WHAP20. Normal camber of unsealed pavements shall be 5 to 6%.

9.4.10 Drainage and Culverts (Road Drainage) (ITS Section 3, Clause 3.2.14)

Channels shall generally be provided for the efficient drainage of surface water (refer to the relevant table in the appendices or relevant District Plan) and shall be graded to outlets at regular intervals not exceeding 150m. On steep grades where channels are subject to scouring, protection work may be required.

Swale drains may be allowed in suitable locations at the District Council’s discretion.

Culverts, where required, shall be designed in accordance with approved engineering standards. Notwithstanding the outcome of any design calculations, no culvert traversing a road or vehicle entrance shall be smaller than 300mm in diameter.

In non-urban subdivisions where stormwater from the road formation and adjoining properties cannot be discharged via either open channels or a piped system to an approved outlet, the construction of drilled and lined soak holes and/or roadside berm drainage beds are options. Any application for this type of disposal system must be accompanied by results of soil percolation tests, specifications and design calculations for Council’s approval. The design and testing of these drainage systems shall be carried out by an approved geotechnical engineer.

9.4.12 Street Lighting (ITS Section 3, Clause 3.2.20)

For intersections where any leg has an AADT > 1000, intersection flag lighting shall be required.

In rural areas where design speeds are greater than 80kmh, slip-base frangible approved lighting columns shall be used.

Alternative street lights may attract an additional whole-of-life cost charge.

9.4.13 Intersections (ITS Section 3, Clause 3.2.9)

• The location of intersections shall be chosen to ensure adequate spacing and sight distance is available for all vehicle movements.

• New intersections shall not be designed to form crossroads with existing roads. • Intersection design shall be in accordance with Austroads “Intersections at Grade” (Part 5). • Safe Intersection Sight Distance (SISD) shall be provided at any intersection, in accordance with the

pressure of 200 kpa; • close control valve to isolate the installation; • record pressure readings at convenient intervals for 50 minutes; • if the pressure does not rise, or falls after an initial rise, a leak must be suspected.

The pressure shall be maintained for a period of 60 minutes without makeup pressure and during the period of the test, the test section should show no evidence of leaks and is allowed a max of 10% loss in pressure due to expansion of the pipe. Before arranging connection to the existing reticulation, the Engineer or Council may require a similar test after completion of backfilling and any other adjoining works which may affect the water reticulation.”

9.7.16 Disinfection (ITS Section 6, Clause 6.3.9)

As per HCC requirements except that other approved chlorine-based disinfection agents may be used as an alternative to tablets.

The minimum free chlorine concentration allowed shall be 3 mg/litre (instead of 10) after 24 hours contact time.

9.7.17 As-built Plans and Asset Details (ITS Section 1, Clause 1.7.3)

As per HCC requirements except that As built plans and associated data in the case of subdivisions shall be sent to:

Asset Information Officer Water Group Waikato District Council Private Bag 3068 Ngaruawahia

Electronic files are to be emailed to “[email protected]” (include in the subject heading the WDC Subdivision Consent Number and the Subdivision name and stage).




9.8 Landscape

9.8.1 Fencing (ITS Section 7, Clause 3.2.5)

Fencing is required for all work on esplanades.

9.8.2 As-built Information (ITS Section 1, Clause 1.7.3)

The As-built records are seen as a crucial part of subdivision development and WDC construction projects. Consequently, the Certificate of Practical Completion and / or final payment will not be issued until As-built records are submitted and accepted by the Engineer. The Contractor shall prepare and submit to the Engineer, copies of the as-built information on the Asset Information forms provided (Appendix C). All information provided is to be of good quality and accurately titled, numbered, cross-referenced, and dated. Positions of all installed components shall be recorded as the works progress for inclusion in the as-built drawings. Completed Asset Information forms shall be sent to:

Electronic files are to be emailed to “[email protected]” (include in the subject heading, the WDC Subdivision Consent Number and the Subdivision name and stage).




9.9 Network Utilities

9.9.1 Location of Above Ground Services Utility location drawings shall be submitted to the General Manager Roading and Projects for approval prior to any works commencing. Where the adjacent carriageway design speed is 80kmh or greater, all new services to be placed above ground shall be outside the Clear Zone defined in the WDC Table 3.1, unless specifically authorised in writing by the Roading Group Manager. This shall include service poles (unless frangible or where AADT >1000 slip-base type installations shall be specified) and stays, as well as service cabinets and pedestals.

9.9.2 Waterway Crossings Any services crossing drains or waterways within the road reserve shall do so without utilising Council road bridges or culvert crossings unless specifically authorised by the Roading Group Manager. Any such approval will be given at Councils pleasure and the services shall be relocated, at the service owners cost, at Councils request at any time.

9.9.3 Location of Underground Services (As-built Drawings) An electronic record shall be provided suitable for direct input to the Council GIS system, (ie: Mapinfo Tables in NZTM) showing the location of all buried services within the road reserve. Depth and detailed (commercially-sensitive or otherwise) specifics of the services are not required (unless the stipulated minimum cover has not been achieved). This information is necessary for the management of the road reserve asset, including forward planning of future roading and services development.

9.9.4 Broadband The developer shall make arrangements with a broadband network provider to provide for the supply and installation of broadband services. This shall involve the design and installation of appropriate ducting, in readiness for the installation of broadband cabling.

Where a broadband network provider is not able to provide a suitable layout then the developer shall use a nominated Broadband designer to provide a suitable detailed design at his expense.

Installation of broadband services must comply with the National Code of Practice for Utilities Access to Road and Rail Corridors, and National Environmental Standards for Telecommunications Facilities:

1. The reticulation shall be provided underground to a minimum final cover depth of 600mm below finished surface level. A suitable copper location wire shall be installed with the duct.

2. The reticulation shall be installed in the road berm, parallel to property boundaries, where possible. All properties shall be serviced.

3. The reticulation shall not compromise or obstruct other infrastructure in the road corridor and should also take into account the potential impact on other utility infrastructure. The reticulation shall not be located within 400mm of any Council service. If this cannot be achieved, Council may require the developer to undertake post construction CCTV inspection of Councils services, at the cost of the developer to ensure that no damage has occurred to these Council services during installation and construction. The developer shall consider future access points to avoid conflict with other infrastructure.

4. The ducting shall have a minimum internal dimension of 100mm diameter. 5. The ducting shall be uPVC plain wall pipe with a minimum SN 4 rating.



6. The ducting shall provide for the installation of fibre optic cabling and shall adhere to minimum bending radii requirements for the cable on all changes of direction

7. The ducting shall be purple in colour. 8. The layout of the ducting should be such as to minimise disruption and disturbance when

cabling is installed. 9. The design of the ducting shall reduce and minimise the requirement for ongoing

maintenance and ensure the maximised lifespan of the infrastructure. 10. Should an above ground cabinet or chamber be required, this shall comply with the relevant

provisions of the District Plan. At least 20 working days notice shall be given to Council of the developers or Telecommunication operators intention to install a cabinet or chamber on Council owned or controlled land.

11. Due to the advancement of ducting materials and specifications, council will give consideration to alternative materials and specifications being offered on a case by case basis.

12. The nominated Broadband designer shall supervise the installation and confirm in writing that it has been constructed to a suitable standard prior to the Section 224 being issued.

13. GIS based as-built records and drawings identifying the layout and, depth of the ducting, bends and joints shall be provided to Council

Hamilton Infrastructure Technical Specifications – Section 9 Waikato District Council Supplement Waikato D. C. Waikato District Council Road Classification Table Page 24

Standards for Road Classification Table (a) Reserve width of a private access will be calculated on the basis of current lots plus any potential lots on further subdivision. (b) The sealed carriageway, or unsealed pavement construction shall be centrally located within the road reserve or private access to

enable future development including more seal width. (c) The natural gradient along the access route within 10 metres of the road boundary must be less than 12 degrees. (d) No exit roads must have sufficient turning dimension to enable a 90 percentile car to enter and leave in a forward direction without

reversing. The design dimension should be sufficient to enable a 90 percentile truck to enter and leave the no exit road in a forward direction after a three-point turn.

(e) Construction of a road or access servicing 5 or more allotments, or 2 or more activities, must have sufficient road reserve width to: • accommodate any retaining structure or slope necessary to support the road or adjacent property, and • achieve a complying horizontal alignment and • accommodate any turning area required by these standards and • service the potential number of residential units, calculated by zone rules for residential density and possible controlled activity

subdivision, and • service the traffic generation from non-residential activities likely to use the access, and • include passing bays on a single lane access, where necessary, having regard to topography of land, sight distances and usage, and • include an area at the end of a cul-de-sac or no-exit road to allow a 90 percentile two axle truck (HGV) as defined in Figure 3 to

undertake a three-point turn.
