Local Knowledge, Practical Experience
QS Mate was built around the Canterbury construction market. Param has worked on new builds, renovations, multi-unit developments, and trade packages across Christchurch, Rolleston, Selwyn, and surrounding areas. That local knowledge shapes every estimate, review, and report we produce.
- New home builds & renovations
- Multi-unit & townhouse developments
- Trade coordination & subcontractor packages
- Subcontractor take-offs & tender submissions
- Tender preparation & builder quote reviews
- Cost tracking & variation management
Why QS Mate Was Started
Most homeowners and small developers don’t have a quantity surveyor in their corner. Builders and subcontractors often price work without independent checks. QS Mate was set up to change that — to give residential clients the same level of cost clarity and professional support that large commercial projects take for granted. That includes tradies and subcontractors — who deserve the same pricing confidence and document support when bidding for work.
