Tendermark is a tender comparison tool for building surveyors. The surveyor authors or uploads a Schedule of Works — the structured list of work items priced in a tender. Contractors price against that Schedule, either by completing an online pricing form or by returning a document (PDF, spreadsheet, scan, or photograph). Tendermark extracts the contractor's prices and produces a side-by-side comparison table.

What the AI does: Tendermark uses a large language model (Anthropic Claude) for three distinct tasks.

• Contractor return matching. For every uploaded return — whether Excel, CSV, PDF, Word document, scanned document, or photograph — Claude reads the content and maps each contractor price to the correct Schedule of Works line item. The file is preprocessed into a readable form first (cell values extracted from spreadsheets, text extracted from PDFs); Claude then handles all line-item matching. This is the primary use of AI in Tendermark and applies to every contractor return regardless of format.
• Schedule of Works parsing (fallback only). When a surveyor uploads a SoW in an unusual format — a scanned document or prose-style Word file — Claude identifies the line items. Standard formats such as Excel and CSV are parsed by code without AI involvement.
• Tender Analysis Report narrative drafting. Three sections of the report are drafted by Claude: Arithmetical Accuracy (discrepancies between each contractor's stated and implied totals), Anomaly Handling (observations on flagged pricing items), and Summary of Submissions (price-difference analysis across contractors). These drafts appear in the report editor marked as AI-generated, pending the surveyor's review and approval before export.

What the AI does not do: Tendermark makes no professional judgements, gives no recommendations, and produces no output presented as a professional opinion. It extracts, organises, and drafts — the surveyor interprets and decides. Every extracted figure includes a confidence score so the surveyor can see where the AI is uncertain. Anomalies are flagged for the surveyor's review, not acted upon automatically. The Recommendation section of the report — the surveyor's professional opinion on which tender to accept — is never AI-drafted and requires the surveyor's own input.

What the surveyor must do: Review all extracted output before relying on it. Verify anomaly flags with professional judgement. Read and edit the AI-drafted narrative sections — they are generated drafts, not finished text. The Tender Analysis Report shows the surveyor's name as the author; the surveyor remains professionally accountable for all of its content. No report should be sent to a client without the surveyor having reviewed and approved the output in full.

The cleaner audit trail — contractor invitations: When a contractor prices online via Tendermark's invitation link, their figures arrive already structured — no AI extraction is involved. Every action (viewed, saved, submitted) is logged with a timestamp and the contractor's IP address. This produces the most transparent possible audit chain and is the recommended approach where contractors are willing to engage digitally.

Before uploading client documents to Tendermark, confirm that your client engagement terms or data processing agreement permits the use of AI-assisted tools for processing their pricing information.
