Learn about Commercial & Specialist Contractors
On a New Zealand building site, commercial and specialist contractors take on defined work packages, such as excavation for foundations or construction of an access road. Earthworks contractors shape the ground to specified levels, while foundation specialists work to the structural design. Ground reports and finished floor levels help establish where one contractor's scope ends and another's begins.
Commercial & Specialist Contractors
The Commercial & Specialist Contractors category also includes house lifters and piling specialists, alongside roading contractors. Lifting an existing house allows access for work beneath it, but temporary support needs to be planned before the structure moves. Define the extent of pavement work for a road or vehicle access and where it meets drainage, rather than leaving those boundaries to be settled on site.
What should be included in a specialist contractor's quote?
Ask for a defined scope with exclusions and allowances for uncertain ground conditions. Check whether disposal charges and any required testing are included, so quotes can be compared on the same basis.
When can demolition work begin?
Confirm any required consents and arrange for services to be disconnected before demolition starts. Have potential asbestos assessed before materials are disturbed, with removal requirements agreed in advance.
How do piling specialists relate to foundation specialists?
Piling is one method of supporting a foundation by transferring loads to deeper ground. Use the structural engineer's foundation design to establish the required expertise, as the two contractor scopes can overlap.
