A new tilt-slab facility, delivered around a live school programme in Glenfield.
Wairau Valley Special School serves students with complex learning needs. The Ministry of Education needed a new 1,000m² tilt-slab complex built on the existing campus — with zero disruption to teaching, safe separation of site traffic, and no interruption to pickup and drop-off. Access was tight, the site was small, and the programme had to absorb the school calendar.
As main contractor, we coordinated every trade on site against a programme built around the school day. Heavy lifts were sequenced for before-school and after-hours windows. Site traffic was routed through a dedicated gate with time-banded access. Scope additions came through during the build — from the Ministry and from the school. Every variation was priced in writing and agreed before work proceeded. No PC-sum surprises at handover.
Complex practical completion delivered on the contracted date. Full PS3 producer statement, O&M manuals, and as-built drawings delivered as a single handover package. Zero recorded safety incidents across the full programme on an active, vulnerable-user site.
Site captured and assessed before contract pricing. No blind allowances carried into the job.
Every scope change priced and agreed in writing before we picked up tools.
Programme built around the school calendar. Heavy works scheduled to minimise disruption.
PS3, O&M manuals, and as-builts delivered as one package at practical completion.
KDB held price through scope changes most contractors would have used to re-open the contract. Programme discipline was exceptional — no disruption to the school term.
Term-time delivery is our default, not a compromise. One business day reply.
