A bridge replacement on a live rural road for a small district council. The complexity here was contractual rather than structural. Completing the NZS 3910:2013 schedules for a job like this means choosing the terms rather than copying them, then being accountable for how that risk allocation performs through tender and construction.
I wrote the contract documentation, took the job through tender to award and then administered it on site as Engineer’s Representative. I did not design the bridge.
What I did on this project
- Wrote the NZS 3910:2013 contract documents, the job specification and the special conditions
- Made the contract measure and value rather than lump sum, because the abutment ground conditions carried quantity risk better remeasured than priced
- Required an MS Project programme updated monthly with a seasonal inclement weather allowance, so a wet winter would be argued against a baseline rather than after the fact
- Built the schedule of prices through 4 revisions and prepared the Engineer’s estimate with the reasoning recorded against each section
- Sat on the tender evaluation team and assisted with the debrief meetings for unsuccessful tenderers
- Administered the contract through construction, including the safety and environmental plans, regional council notifications, site inspections and meeting minutes
