Win the right projects. Ignore the bad ones.
Stop letting your conversion rate depend on human reading time. The Bid Agent devours Tender Documents (DCE), prices your Bills of Quantities (BOQ) and identifies toxic opportunities before you even start estimating.
Responding to a tender requires analysing thousands of pages (Particular Administrative Conditions, Technical Specification, Drawings, Schedule of Rates) in a matter of days. Your commercial teams are overwhelmed and commit the company to non-existent margins. Vonbuild tips the balance.
Victory is decided by processing capacity
Quadruple your response volume whilst increasing the accuracy of your bids.
Tender Triage and Risk Scoring
As soon as a tender is published, drop the massive ZIP file into Vonbuild. The Agent reads the entire dossier. It instantly extracts the award criteria, eliminatory clauses, delay penalties and major technical requirements. It assigns a Profitability Score (Go / No-Go) based on your company strategy.
BOQ generation and assisted quantities
The Agent cross-references the architect's drawings with the Technical Specification to pre-populate the lines of your Bill of Quantities (BOQ). If a quantity is missing or a specification is ambiguous, it automatically generates the list of Q&A queries to submit to the Design Team.
Price memory (Knowledge Graph)
The Agent is not amnesiac. When estimating a cost, it queries the Knowledge Graph (Neo4j) of your past projects. It compares the unit prices requested today with your actual cost prices from 6 months ago on similar projects. Your commercial bids are based on your financial truth, not on back-of-the-envelope estimates.
Technical submission pre-drafting
Using the history of your best responses, the Agent generates the framework of your technical submission, adapts the health and safety documents, inserts the CVs of the relevant teams and drafts the execution methodologies (SOPs) specific to the constraints of the target project.

Scenario: tender for 45 apartments
A developer issues a tender for a 45-unit residential block, 4,200 m2 SHAB. Response deadline: 10 working days. Your team would need 6 days. The Bid Master does it in a few hours.
Reading and auditing the Excel file
The agent ingests the tender BOQ, an Excel file with 342 lines and 14 embedded VBA macros. It executes each macro, verifies the consistency of the totalisation formulae, and detects 3 inconsistencies: a unit price line that does not carry through to the work package total, a quantity rounded down instead of up, and a duplicate article code with different prices.
Detecting omissions: Technical Specification vs BOQ
The agent cross-references the 87 tender drawings and the Technical Specification with each line of the BOQ. It detects that the Technical Specification requires enhanced acoustic glazing 44.2 on the north facade (proximity to a railway line), but the BOQ only provides for standard double glazing. Cost of the omission if undetected: 38,000 EUR in lost margin. The agent proposes the corrective line item.
Price comparison via vector search
The agent queries your database of 47 previous projects via RAG vector search. It compares the unit prices proposed by your subcontractors with historical averages by region and project type. The electrical bid from Company C is 18% below market: an under-estimation risk to be verified.
Complete bid ready to submit
The response dossier is compiled: corrected BOQ with the 3 inconsistencies resolved and the acoustic glazing line item added, technical submission structured against the scoring criteria extracted from the RC, preliminary programme, similar project references. You review, adjust the pricing strategy, and submit.
