NZS 3917 is the term services contract: the form councils use for water, parks and waste operations and maintenance. It borrows its structure from NZS 3910, including the Engineer, but the job is different in three ways that matter.
It runs for years
A works contract has a start, a practical completion and a defects period. An operations contract renews. The Engineer’s decisions in the first six months become the way things are done for the next six years, so the early determinations have to be procedurally robust, contractually compliant and defensible, precisely because they will be relied on as precedent.
We build that in deliberately: a familiarisation period at the start, then a structured review of workload and fee at three months and annually, so the Engineer function is sized to the contract as it actually runs rather than as it was tendered.
It is governance, not operations
The temptation on a term contract is for the Engineer to drift into managing the service. That is the contractor’s job and the council’s. Our attendance is focused on contract governance and clarity of contractual positions: payment, variations, performance measurement, notices and decisions. The Engineer’s Representative handles the routine administration and performance monitoring; the Engineer keeps the independent functions the contract expressly reserves.
Independence has to be written down
On a works contract the Engineer’s impartiality is tested a few times. On a term contract it is tested every month, on every claim and every performance assessment, against a counterparty the council will be living with for years. So we put it in the consultancy agreement: where the Engineer is required to act impartially under NZS 3917, that obligation takes precedence over the client’s general right to instruct us. The council agrees to that up front, which is the point.
The formal duties, decisions and certifications under the contract are undertaken by me personally. Urban Solutions staff support the administration, but the Engineer role itself is not delegated.
What a council should expect
- Stability and assurance through disciplined contract administration, impartial decision-making and practical oversight of service performance.
- A disciplined, transparent and commercially pragmatic Engineer function. Not an adversary to the contractor, and not an advocate for either side.
- Written decisions with reasons, on a standard template, with the clause reference, filed in a register the council can open at any time.
- Early notice if the effort the contract needs is running ahead of the fee, rather than a surprise at renewal.
Where we do this
We are the Engineer under NZS 3917 on three district-wide operations contracts for one council: three waters, parks and reserves, and solid waste. Together they cover most of what a district council physically does every day.
