How it works

From Schedule of Works to sign-off, in one tool

The surveyor's tender and contract administration workflow, in a single audit-trailed environment. Six steps from drafting the SoW to sharing the final valuation with the client.

1

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 — 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 — unusual price spreads, missing items, 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. The footer carries the Prepared by you and your firm · Assisted by Tendermark attribution that satisfies the RICS AI Standard client disclosure requirement.

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 — 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 and a client-ready burn-up

At each interim valuation, Tendermark builds a burn-up chart from the line-item progress the surveyor records — work completed against work contracted, by trade and across the project as a whole.

The surveyor still authors the valuation. Tendermark assembles the numbers and renders the progress chart; the certificate carries the surveyor's professional judgement.

RICS AI Standard

The compliance pack your firm needs alongside every tender

Under the RICS AI Standard (effective March 2026), every surveyor using AI tools must produce a due diligence disclosure, maintain a risk register, and disclose AI assistance to clients. Tendermark ships the artefacts you need — and the audit trail across the lifecycle backs them up.

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.

Audit trail on every tender

Every contractor submission and report generation is timestamped and attributable — supporting RICS audit trail expectations.
