This is also a flexible unbound granular pavement with a total thickness of 300mm. The pavement was constructed in two layers with a 150mm layer of subbase of AP65 generally in accordance with TNZ M/4 except for grading and broken faces. The top layer is 150mm depth of AP40 basecourse again generally in accodance with TNZ M/4 except for the broken faces. The pavement was constructed in accordance with TNZ B/3 - April 2000

Measure and Value contract assessed on weighted attributes. Towards the end of the physical works contract the contract was converted to a negotiated lump sum which covered the pavement construction and the balance of the works


2. Pavement thickness - there was no necessity to increase the pavement thickness from that designed. However the Contractor did propose that the pavement costruction be carried out under TNZ Specification B/3 and this was adopted.

Bridges converted to lump sum "design and build" due to market submitting higher than expected pricesComment

1. When the tender estimate was submitted for independent assessment, it was found to be 2 M under market value, hence market value was a known risk2. Noise and dust was a risk due to the borrow site operation within residential and industrial areas, watering kept it in control and complaints were dealt on a case by case basis3. Establishment of landscape planting was identified as a risk, thus a 5 year maintenance programme incorporated into the contract4. Relocation of Nelson Regional Sewer Authorities services was a high risk to the community, special contingency measures were specified and came into play during construction

Chip seal over flexible unbound granular layers (138 6882m2), 40 mm AC (21,011m2). Pavement layers comprised 250AP 40 over 400-500 mmm Greenhill bulkfill material. Alternative design of contractor of 150 mm AP40 and 100mm AP75 layers combined into a single AP40 layer.

Critical issues which influenced the successful completion of this project included the requirement to construct a temporary split level crossing over State Highway 7 to allow 410,000 cubic meters of borrow to fill material to be utilised, reclamation of tidal estuary margins and liaison with major processing & manufacturing companies to ensure construction work had no detrimental effect. Major value engineering was completed with all 4 overbridges being negotiated to be undertaken as design & build.
