A Priced Spec (priced spec) is a measured list of every material, labour and plant item required to build a project, prepared from drawings and specifications to rules. It lets multiple contractors price the same scope on the same basis, exposing risk and revealing the true market price. Costed prepares independent priced specs for projects from £250k to £50m across London and the Home Counties.

Cost planning is the discipline of fixing a defensible construction budget early in the design process and then policing it through every design stage. Costed prepares elemental cost plans aligned to the design stages, benchmarked against current London market rates, so design decisions are taken with their cost consequence already on the table, not discovered at quote.

Quote analysis is the independent review of returned contractor prices against a common priced spec or pricing schedule. Costed compares every line, flags anomalies, isolates qualifications, normalises pricing assumptions and produces a recommendation report that tells you not only who is cheapest, but who is most likely to actually deliver at the price they quoted.

An Independent Monitoring Surveyor (IMS) acts for the lender on a development-finance loan. We confirm what has actually been built, certify drawdowns, audit cost-to-complete, and surface programme or budget risk before it threatens the loan facility. Costed provides transparent monitoring across residential, mixed-use and commercial schemes for UK clearing banks, challenger lenders and private credit funds.

Post-contract cost expert is the work that protects the price you signed. Costed runs monthly interim valuations, assesses every variation against the contract, maintains the cost report, tracks contingency erosion and forecasts the outturn, so the closing out the build closes near the contract sum, not a long way past it.

The closing out the build is the contractor's last opportunity to recover what they think they are owed, and your last opportunity to challenge it. Costed prepares, scrutinises and negotiates final accounts using the original contract sum, the agreed variation register and the documented quantum, so that close-out reflects what was built and contracted, not what was claimed.

Construction disputes are won or lost on documentation. Costed provides independent quantum analysis, prepares Scott Schedules, drafts expert cost expert reports and supplies adjudication-ready evidence under the Construction Act. We work for employers, contractors and subcontractors, but only one side per dispute.
