Never copy a tender return into a spreadsheet again.

Tender comparison and contract administration for building surveyors.

Spreadsheet, PDF, even a photo of a marked-up printout: however a contractor's return arrives, it lands in one like-for-like comparison against your Schedule of Works, with anomalies flagged for your review. You always make the call.

Once the contract is awarded, Tendermark stays with you: variations, interim valuations, every step on the audit trail.

Built to the RICS AI Standard.

How it works

Two jobs, one tool. Run the tender, then administer the contract.

Compare the returns and award the work. Then keep going in the same place, with the same figures and one audit trail, all the way to the final certificate.

Author or upload your Schedule of Works

Compose a Schedule of Works directly in Tendermark, or upload your existing Excel, PDF, or Word document. Line items are processed and structured automatically, with sectioning, units, and notes preserved. Drag-and-drop reordering, Excel paste, and bulk edit are built in. Most surveyors author rather than upload, and the editor is built for that.

Invite contractors to price

Send each contractor a unique link from the tool. They open it from their email inbox, and price each of your SoW line items directly. No account, no software download, no spreadsheet to format. Progress saves automatically; they can return and edit until they submit. Returns land in Tendermark as they come in, ready to compare.

Contractors who prefer to can still send files. Tendermark accepts Excel, PDF, Word, scanned documents, and phone photos. The invitation link is the easier path for most; the upload path is there for the ones who need it.

Review the comparison and issue the report

Tendermark builds the comparison table as each return lands. Anomalies such as unusual price spreads, missing items, or lump-sum line items hiding detail are flagged for the surveyor's review. The surveyor decides what to do about each; Tendermark surfaces them and tracks the decision in the audit trail.

When the analysis is ready, the report exports with your firm's branding: PDF for client emails, Word for further editing, or a read-only share link for colleagues.

Award the contract

When the surveyor decides on a contractor, Tendermark records the award and locks the priced Schedule of Works as the contract sum. The award decision is captured in the audit trail with the surveyor's reasoning, useful if a client or RICS Regulation asks how the contractor was selected at a later date. The unsuccessful contractors are sent an automated notification. The appointment letter and contract sit alongside, ready for the JCT handoff.

Manage variations against the contract sum

When a variation is priced, whether an addition, an omission, or a change in spec, Tendermark sits it against the original contract sum and flags it for the surveyor's review. The surveyor decides what's reasonable; Tendermark surfaces what's changed and tracks the running total.

Each variation becomes a record in the audit trail, attached to the contract, with the surveyor's notes alongside. At a later date, when a client asks how a figure was arrived at, the trail is there.

Track progress with interim valuations

At each interim valuation, Tendermark builds a burn-up progress chart from the line-item progress the surveyor records: work completed against work contracted.

You still author the valuation, but Tendermark assembles the numbers and builds the progress chart.

RICS AI Standard

A compliance pack for your firm, and an audit trail on every tender.

From 9 March 2026, the RICS professional standard on AI requires you to run due diligence on your tools, keep a risk register, and tell clients in writing when AI is involved. Tendermark gives you what you need for each: a plain-English account of how it works and handles your data for your due diligence, a risk register template to complete, and client disclosure wording for your engagement terms. Every tender then keeps a timestamped audit trail, and you stay the decision-maker on every figure.

How Tendermark works

Plain-English explanation of what the AI does and doesn't do — suitable for due diligence records and your firm's AI risk register.

Risk register template

Pre-populated for Tendermark use. Covers failure modes, data handling, and surveyor oversight obligations. Fields left for your firm to complete.

Terms of engagement language

Standard client disclosure text, ready to copy into your engagement terms. Meets the RICS client notification requirement.
