at the beginning of each project and is monitored throughout the construction to help ensure smooth progression and successful outcome. Significant variations in the final design may have to be returned the Asset and Services Committee for verification and approval.

These are normally pipes and pump stations created as part of a land development subdivision. The assets will be accepted only if they are designed and constructed to rigorous standards prescribed in the Code of Practice for Subdivision (NZS4404. 2004) and amended by MDC. The process is supervised by the Infrastructure Project Engineer and subject to his final approval of quality. Purchased Assets - Specific assets may be purchased directly by council staff. Generally there are sufficient in-house engineering skills to select the suppliers and evaluate the purchase options. External assistance from consultants may be sought for specialist plant and equipment. 4.6 Disposal Plan There is a need to plan for the disposal of assets that are no longer operational. The plan recognises the costs and benefits of redundant assets. Underground assets are normally decommissioned and left in the ground. They have a residual value; they can often be re-commissioned or the pipelines used as conduits for other services. However they may also represent a continuing cost of ownership through the liability of collapse or ground subsidence, require continued maintenance, create unwanted flow paths for groundwater or present an obstacle to other services.
