COS / Civil works

For civil works: roads, bridges, infrastructure.

BOQs with thousands of items, public clients, revisions mid-tender and equipment that drives the price. COS keeps all of it in one record.

Where it gets stuck today

01

BOQ revisions

The client issues revision 2 two weeks before the deadline and someone has to compare 1,500 items.

02

Price depends on equipment

Paver, roller and truck output set the asphalt price, and those numbers live in people's heads.

03

Measurement book and bills

Quantities are added up from the diary at month end while the supervisor waits.

What COS does for you

Example from the walkthrough

Revision 2 changes asphalt thickness from 5 to 6 cm. COS recalculates the item from the formula, shows the €1.71/m² difference and notifies the estimator.

01AI tender review

Upload the tender. AI reads everything and flags the risks.

Risks, penalties and deadlines from public tender documents, with the source page.

The team and management know what they are getting into before the first hour of estimating.

02Versions and changes

A new revision arrived? COS marks it and alerts the people assigned.

Revisions compared item by item, owners notified at once.

No change slips through, and everyone knows what changed in their part.

07Formula library

Every estimate becomes a formula the company reuses.

Formulas for asphalt, concrete and earthworks with your own output rates and plants.

Every next BOQ goes faster, and the knowledge stays in the company.

14Work planning

Crews, machines and deliveries on one plan.

Pavers, rollers and trucks on one plan across all sites.

Less idle time, fewer delays, fewer phone calls.

16Measurement book

The measurement book fills from the diary and follows the contract.

17Extra and additional work
