A displayed budget is not your site quotation
An official design page can be a starting point, but its displayed amount is not a contractor’s offer based on your plot and scope. The inspected information did not establish that each amount was updated to the material and labour prices on our review date.
Record the design name, URL, access date and supporting documents. Ask what is included, how area is measured and which price period is used. This article applies no unsupported percentage adjustment.
Match foundation options correctly
DPT’s Economy House 3 page contains foundation-related budget information that needs to be read with its description. A zero value in a budget field should not be treated as proof of zero cost.
Have the responsible designer assess foundation suitability using site information before requesting prices. Choosing the smallest displayed figure may compare different scopes. No foundation is selected for a specific plot here.
Make inclusions and exclusions visible
Use the same work headings with every bidder: building, external works, utilities, site preparation and requested finishes. Identify items the owner must supply separately.
When using a bill of quantities, check its version, date, units, quantities and scope against the intended drawings. Per-square-metre prices have limited meaning when the area or work included differs.
Keep unresolved questions explicit
List missing site information, proposed changes to the standard design and surveys that remain outstanding. Ask the relevant professionals how each will be checked rather than filling gaps with guessed numbers.
Obtain original drawings through the source agency under its stated conditions. Asset.red does not rehost unlicensed drawings or quantity files and does not certify budget sufficiency.
