DUCTWORK ESTIMATING SERVICES
A take-off you can trace.
A build-up you can review.
A ductwork estimate connects measured quantities to fabrication, supply and installation costs. Scope the role around the parts of that process your team needs help with.
01 / QUANTITIESDuct take-offs
Rectangular, circular and flexible ductwork; fittings, branches, transitions, grilles, diffusers and dampers within the agreed trade boundary.
- Separate system, size, material and location.
- Record length, surface area or counts as required.
- Keep insulation and lining identifiable.
02 / COST BUILD-UPPricing support
Apply your approved supplier or fabrication rates and labour basis. Keep material, fabrication and installation allowances separate enough to check.
- Flag quote validity and exclusions.
- Identify supports, access and delivery allowances.
- Leave mark-up and tender decisions with you.
03 / CHANGE CONTROLRevision tracking
Track what changed between drawing issues, rather than replacing a total without an explanation.
- Keep drawing numbers and revision references.
- Log quantity changes and pricing queries.
- Separate confirmed scope from assumptions.
Agree the output before work starts. A useful handover can include marked-up PDFs, an editable quantity or cost workbook, a revision register and an assumptions list. Confirm the candidate’s software capability and licence arrangements; access to a particular platform is not assumed.
