These are the documents we ask for before preparing a scope and quotation, and how each one affects the result.
Drawings, latest revision
Architectural and structural drawings, plus MEP drawings if they are in scope, in PDF or DWG, with the revision schedule. Pricing from an out-of-date revision is one of the most common causes of quantity differences.
- Send the complete set, not selected sheets, so references between sheets can be traced.
- DWG files measure more accurately than scanned PDFs.
- If there is more than one revision, state which one is to be priced.
Technical specification
The specification fixes what the drawings do not show: concrete grade, insulation type, tile class, and test and acceptance criteria. A single item such as “internal painting” can double in price from one specification to another.
Bill of quantities, if available
If the owner or consultant has a bill of quantities, we price it as issued, then check its quantities against the drawings and report any differences before submission, rather than changing it without a record.
Location, area and site conditions
- Project location (city and district, or coordinates), it drives transport and labour costs.
- Approximate area and number of floors.
- Constraints: permitted working hours, equipment access, work inside an occupied building.
Scope and target date
State what the quotation includes and excludes: is MEP in scope? Is supply by the contractor or the owner? When is completion required? The date sets the team size, and so affects the price.
What you receive from us
A quotation built on clearly described items, with a list of assumptions, exclusions and any gaps we found in the documents, so that quotations can be compared on the same basis.
