IT-1 GENERAL PROVISIONS

Updated 01/07/2014 Page 1

IT-1.1 General

The Consent Holder's Representative or the Engineer are responsible for ensuring that theformal inspections/testing is undertaken in accordance with the IDC. Council also undertakesrandom informal inspections during the course of the works.

Council attends these inspections/tests:

a) As a co-stakeholder of infrastructure development with the emphasis on the constructionof quality assets that will be vested in Council ownership and/or private assets thatconnect to and therefore have an effect on public assets.

b) To ensure good industry practice that benefits all stakeholders, especially the generalpublic and to ensure the quality, longevity and maintenance of the assets in the future.

Development Works

Type 1 Process

a) Unless notified otherwise in the Development Works Approval, Type 1 developmentsrequire the following 2 inspections:i) A pre-backfill inspection for all services intended for Council ownership.

ii) The Final Inspection.

b) Usually, no formal testing of services is required for smaller developments where theonly assets being created are service connections or short laterals or connections toreticulation mains.

c) Testing is required where the services being constructed involve reticulation mains,ridermains, manholes or the like. In these cases testing shall be undertaken inaccordance with IT-1.4 Asset Inspection/Testing Requirements.

d) The final inspection will ensure that assets constructed meet the required standards.

Type 2 Process

a) Unless notified otherwise in the Development Works Approval, Type 2 developmentsshall undertake the inspections and testing in accordance with IT-1.4 AssetInspection/Testing Requirements and IT-1.6 Final Inspection.

Capital Works

a) Refer to the contract documents for testing requirements.

Inspections and tests organised or undertaken by the Project Engineer shall be asprovided for by this section of the IDC.

IT-1.2 Minimum Requirements

a) As a minimum, Council will undertake formal inspections/tests as referenced within thissection of the IDC.


Page 2 Updated 01/07/2014

b) In some cases additional inspections/tests may be required. These additionalinspections/tests will be outlined in the Development Works Approval or requested whenunforeseen circumstances arise or to resolve a difference of opinion. These additionalinspections/tests will be advised by Council where required.

c) Council will not attend any formal inspections/tests where the work to be inspected/testedhas not been pre-inspected/tested and confirmation provided to Council that theinspection/test is ready for formal inspection/test. Where work to be inspected/tested isnot ready for inspection/testing or the equipment required for the inspection/testing is noton site then Council staff will leave the site and only return when the work is ready forinspection/testing.

d) Where Council arrives for a formal inspection/test and that inspection/test is deemed "notready" to be undertaken, Council reserves the right to cancel the inspection/test andrequire it to be re-scheduled.

e) Council will charge associated costs to the Consent Holder for any inspection/testattended that is deemed not ready and for any re-testing/re-inspection whereinspections/tests have previously been failed.

f) The requirements for application for re-inspection/re-tests are the same as for therequirements for the initial inspection/test.

Where the Consent Holder's Representative fails to comply with these provisions, Councilmay not:

a) Accept the assets for vesting.

b) Allow the new infrastructure to be connected to the existing network.

c) Issue the s224 for the subdivision.

d) Issue building consents or code compliance certificates for any buildings proposing toconnect to the infrastructure.

IT-1.3 Applying for Inspections/Tests

a) Council shall be notified in writing (includes email) by the Consent Holder's Representativeor Engineer at least 2 full working days before the formal inspection/test is required. Therequest to undertake a formal inspection/test shall confirm that the work has beenpre-inspected/pre-tested by the Engineer and Contractor and is ready for inspection byCouncil.

b) The request for a formal inspection/test shall be made to the Development Engineer orCouncil Project Manager assigned to the project. Council will not respond to any requestfor inspection/test from any party other than the Consent Holder's Representative orEngineer or made to any other staff member other than the assigned DevelopmentEngineer or Council Project Manager.

c) If no response is received within 2 full working days, the applicant shall call Council tocheck that Council has received the request. Works may proceed 3 working days afterwritten notification has been sent to Council and no response has been received.



d) Unless otherwise advised, all equipment required for the formal inspection/test shall beprovided by the Consent Holder's Representative on-site and ready for use in theinspection. This includes any equipment required for confined space inspections. Wherethis equipment is not available on site then the inspection/test will be re-scheduled. Anadditional fee will be charged to the Consent Holder for Council to return to the site for therescheduled inspection/test.

e) Where Council is unable to attend a formal inspection/test, it may engage a third party toattend on its behalf. Where this occurs the applicant will be notified in writing, confirmingwhat arrangements/reporting Council may require to certify that the works meet therequired inspection/testing criteria. Once the required reporting has been received by theConsent Holder's Representative, Council will again notify in writing that the works mayproceed.

f) To arrange for Council to observe a formal inspection/test, please contact the assignedDevelopment Engineer / Council Project Manager via writing (email) or phone.

Note: All telephone requests for observation require a written request as well.

IT-1.4 Asset Inspection/Testing Requirements

a) For the requirements of inspection/testing for each different asset group, refer to thefollowing:

i) IT-2 Streetscape.

ii) IT-3 Reserves.

iii) IT-4 Transportation Network.

iv) IT-5 Stormwater.

v) IT-6 Wastewater.

vi) IT-7 Water Supply.

vii) IT-8 Public Lighting.

viii) IT-9 Network Utilities.b) Unless advised by Council, all equipment required for the formal inspection/testing shall be

provided by the Contractor and/or Engineer on-site and be ready for use for theinspection/test. This includes all equipment and requirements for confined space entry.

c) Where applicable, all inspections/tests shall be reported on Council's standardinspection/testing sheets and signed by:

i) The Contractor’s Representative (as the party who constructed the works to beinspected/tested).

ii) The Engineer (as the party responsible for the certification of the works).

iii) Council’s approved representative (as the party acting as co-stakeholder fordevelopment of quality assets on Council’s behalf).

d) Where inspection/testing sheets are not provided, the results shall be formalised in writingby the Engineer and signed as per c) above.



IT-1.5 Random Inspections

Council will, during the course of construction of the development works, undertake recurrentrandom observation of the development works as well as attend formal milestone inspectionsand testing. For large scale developments random inspections will occur, on average, at leastonce per week when construction is being undertaken and once per month at other times.

IT-1.6 Final Inspection

a) A final inspection and walkover with As-Built plans shall be undertaken once all works aredeemed complete.

b) The request for final inspection shall confirm that all physical works requiring inspectionhave been pre-inspected by the Certifying Engineer or Consent Holder's Representative,that all testing has been successfully completed and the site is ready for the finalinspection by Council. This inspection is sometimes known as the pre-(s)224c inspection.

IT-1.7 Liability

Confirmation from Council that a section of development work has passed a formalinspection/test and that work may continue does not free or indemnify the Consent Holder'sRepresentative from certifying that the development works comply with the requirements ofthe IDC, any Resource Consent condition and good industry practice.

g) A complete inspection of all assets prior to s224(c) application is required as specifiedin IT-1 General Provisions.


Council will undertake random inspections of all site features throughout the constructionperiod to ensure good industry practice and compliance with all requirements for theinfrastructure development are being followed.



IT-4.2 Testing

a) Council shall be advised when testing is being undertaken but may choose not to attendthe testing.

b) All compliance testing is to be carried out by an IANZ Registered testing Company IT-4 -Appendix A – Company Requirements for Pavement Testing.

c) It is expected that Contractors will carry out their own uniformity testing in addition to thecompliance testing. While not acceptable for compliance, copies of all of the Contractor’suniformity testing results will be made available to Council if requested.

IT-4.2.1 Subgrade Testing Carriageways

The tests in IT-4.2.1.1 Test Methods shall be completed and accepted before placing anypavement aggregate.

It is the Engineer’s responsibility to ensure soils and bearing testing is undertaken (as maybe required) and to identify and carry out any necessary remedial works on the subgrade(not less than 400mm depth) to achieve the required bearing capacity and, where utilised,deflections necessary at subgrade level.

Testing requirements covered in this section address only the tests required to satisfyCouncil that the finished subgrade of the pavement is competent in both bearing capacityand deflection to support the road pavement.

IT-4.2.1.1 Test Methods

The test method to be utilised to measure and prove the strength of a completedsub-grade for all soil types is the Insitu CBR test method in accordance with NZS 4402Methods of Testing Soils for Civil Engineering Purposes.

Other test methods can be utilised between Insitu CBR tests to confirm the uniformityof the completed subgrade.

The other test methods that can be used for consistency testing are for:

a) Cohesive soils: shear vane testing.

b) Non-cohesive soils: scala-penetrometer testing.

Both methods require calibration against several of the passed Insitu CBR tests.

Benkelman Beam testing is also an acceptable test utilised by the Engineer to test asubgrade for consistency and uniformity of performance. (This is a non-mandatoryrequirement.)

a) CBR Testing:

Insitu CBR tests are to be carried out on all completed subgrades. Tests shall becarried out at 15m intervals on alternate lanes. The subgrade CBR’s shallachieve:

i) CBR ≥7 for modified ash subgrades.



ii) CBR ≥10 for modified sand pumice subgrades.

unless the approved design CBR is different.

The CBR value used in the design shall be the 10 percentile value of the CBRtests taken on the subgrade material. A selection of tests shall be taken at150mm, 300mm and 450mm below final subgrade level.

b) Scala Penetrometer testing (non-cohesive soils only):

The Scala Penetrometer shall be calibrated by performing tests located adjacentto one or more insitu CBR test that meets the approved design CBR orperformance standards referenced in a) above.

Once calibrated the Scala Penetrometer can be used to check the uniformity ofthe subgrade.

Testing with Scala Penetrometer shall be carried out in both wheel tracks of eachlane of the pavement at 10m intervals:

i) The Scala Penetrometer shall only be employed on non-cohesivesubgrades where a significant part of the subgrade particles pass a 9.5mmsieve. The penetrometer shall be bedded into the soil with one (or more)blows. The zero point for depth and the number of blows is taken neglectingthe bedding blows.

ii) Table 1: Scala Penetrometer vs CBR Approximation sets out the firstapproximation co-relationship between the Scala Penetrometer readings innon-cohesive soils and equivalent CBR readings.

iii) Refer to IT-4.2.6 Scala Penetrometer CBR Conversion Chart for theCalifornia Bearing Ratio (CBR) vs Penetration relationship.

c) Shear Vane Testing (cohesive soils only):

The shear vane shall be calibrated by performing tests located adjacent to one ormore insitu CBR test that meets the approved design CBR or performancestandards referenced in a) above.

Once calibrated the Shear Vane can be used to check the uniformity of thesubgrade.

Testing with Shear Vane is to be carried out in both wheel tracks of each lane ofthe pavement at 10.0m intervals:

i) There is no established direct correlation between the Shear Vane and CBRas every soil type has different characteristics, however, by calibratingdirectly to insitu CBR results as in a) CBR Testing above, a localcomparison is useful for uniformity assurance. In general the local ashes forsoils close to optimum moisture content (OMC) and 100% maximum drydensity, the shear strength should be >150 kPa.

d) Benkelman Beam Testing:

Although not mandatory, Benkelman Beam tests for total deflection areencouraged to be carried out on all prepared subgrades. Tests shall be carriedout at not less than 15.0m intervals on alternate lanes. It is anticipated that in



general subgrade total deflections should be 4mm average and not exceed 6mm.Deflections in excess of 6mm shall require remediation of the subgrade or theEngineer will need to reassess the pavement design to ensure the maximum finalpavement deflection is not exceeded:

i) The Benkelman Beam test shall be as per NZTA Specification T/1Benkelman Beam Deflection Measurements.
