A BOQ traced to its drawings
Every item points to the drawing sheet its quantity was read from, and says whether a person confirmed it as printed or edited it.

BOQ and cost review
From drawings to a reviewed bill of quantities.
CapitalLens AD reads the quantities printed on your infrastructure drawings, builds the bill of quantities, prices a line only where your own confirmed cost history supports it, and checks it line by line. No number is ever invented; a missing one stays visibly missing.

How it works
Drawings to a signed-off BOQ, in five steps.
01
Upload the drawings
Vector PDF drawings enter through a data-rights check that records what each file may be used for.
02
Confirm the quantities
Printed schedules and counts are read from each sheet, and a person confirms, edits or rejects every one.
03
Produce the BOQ
Confirmed quantities become bills, sections and items, each linked to its drawing sheet and priced only where a benchmark exists.
04
Review line by line
Checks flag missing items, quantity mismatches and rates outside the benchmark range, and a person signs off each finding.
05
Export the record
The BOQ and the review leave as Excel with live formulas and as a PDF report marked draft until every finding is decided.
- CapitalLens prepares
- It reads, assembles, checks and documents, and prices a line only where evidence supports it.
- People decide
- Every figure that leaves a draft was accepted by a named person.
- Approval stays a governance act
- Independent review is a decision your organisation makes, not something this platform performs.
What you get
Three things a reviewer can rely on.
Rates that show their evidence
A rate comes from your organisation's own confirmed bills, with the range and the number of observations behind it. Where no benchmark exists the rate stays blank, and the line is never counted as zero.
- Minimum, median, maximum
- Observation count
- Price basis date
- Blank, never zero
A review a person can sign
Findings carry a severity, the drawing, specification and benchmark behind them, and a suggested action. Each is accepted, edited or rejected by a named person, and the decision is kept.

- Basis shown
- Named sign-off

Assurance
Built so every number can be explained
A bill of quantities is only worth something if somebody can still explain each line after the people who produced it have moved on.
No number is invented
A quantity is printed on a drawing or it is absent. A rate comes from a benchmark or it is blank. A check that could not run says so.
Every upload passes a data-rights check
Nothing is read, priced or compared until the organisation's right to use the file for that purpose is recorded.
Decisions are kept, not overwritten
A correction is a new record that refers to the one it replaces, and every access decision is written down.
How records are preserved
Approved records cannot be updated or deleted — the database revokes those rights outright rather than relying on the application to behave. A correction is always a new version that references the one it supersedes.
When a record is approved, its report is generated once and stored. Every later download serves those stored bytes after re-checking them against a fingerprint taken at the moment of approval, so a document cannot drift from the decision it records.
Separation between organisations is enforced beneath the application, so a fault in the software cannot expose one organisation's work to another. Every access decision, permitted or refused, is added to a record that nothing can later rewrite.
Product status
Where this build stands
- This is an early release.
- Demo projects are synthetic, rates are benchmark medians from an organisation's own bills rather than tendered prices, and scanned drawings are flagged as unreadable rather than guessed at.
- Quantity rules and rates still require review by a qualified estimator before any figure is relied on.
- No accuracy claim is made, and nothing here carries authority to commit funding.
- Accounts are provisioned by an operator; there is no self-service registration.
