Win construction contracts: create VOB-compliant bills of quantities
Construction tenders are the gateway to new contracts. Creating clear bills of quantities and comparing offers systematically gives you a competitive edge-whether you operate as a general contractor, look to find construction subcontractors, or run a B2B construction marketplace.
Starting point: clear project and tender scope
Do not begin before scope, lots and awarding units are clearly defined. Vague specifications often cause variations, disputes over quantities or quality, and complicate bid comparisons. Fix a defined planning status and document open decisions.
Key questions:
- Which trades will you award (e.g. tiling, shell construction, building services)?
- Which services will be bundled, which tendered separately?
- Where are the interfaces between hired teams, subcontractors and in-house work?
Clarifying these points early prevents capacity issues and misunderstandings, for example whether to hire construction teams or advertise projects specifically for subcontractors.
Prepare documents professionally
Tender documents determine whether you receive comparable and reliable offers. Follow accepted public procurement guidelines:
- Structure the specification precisely and logically.
- Explain technical terms and abbreviations so new bidders understand the project.
- Clearly mark requirements, proof of suitability and deadlines.
A standardized bill of quantities (often in GAEB format in German practice) is recommended: each item should state quantity, unit and a clear description. The better the BOQ, the easier it is to compare anonymised construction bids on platforms. Also consider national and EU thresholds for Germany and Poland, as they affect procedure type, deadlines and publication.
Soliciting offers: structure over chance
Combine direct outreach with digital channels to reach the right providers. Build a network of specialist firms and subcontractors by trade, region and capacity, and use a B2B construction marketplace to extend reach.
Communicate minimum requirements for suitability, references, insurance and capacity, plus strict timelines for questions, submission, bid validity and start of works. A go/no-go check helps determine whether a project fits your strategy before inviting offers.
Comparing offers: transparent scoring matrix
Price matters, but not exclusively. Set award criteria in the tender and disclose their weighting. Typical criteria include:
- Price (total price, unit prices, variation risk)
- Quality (references, qualifications, project organisation)
- Schedule reliability (capacity evidence, realistic timelines)
- Risk (contract terms, liability, securities)
Recommended approach:
1. Verify mandatory criteria: does the bidder meet licences, insurance and reference requirements?
2. Compare prices item by item in the BOQ: are there conspicuous under- or over-prices for key items like tiling or MEP?
3. Apply a scoring matrix (for example 60 % price / 40 % quality) - publish it to ensure transparency.
Anonymised bids help prevent bias from prior relationships and support objective awarding decisions.
Automate the process and improve continuously
Map how tenders enter your organisation, which steps are manual and where data is lost. Build standard documents and checklists and automate document distribution, deadline tracking and reminders.
Use KPIs from past tenders: award rates, typical price ranges per trade, frequency of variations. This creates a scalable process that improves your chances in future tendering and streamlines subcontractor use.
Conclusion
Clear specifications, transparent requirements, reliable timelines and a verifiable scoring matrix for price and quality are the foundations of successful construction tenders. Systematic implementation and gradual automation increase the likelihood of securing suitable contracts and deploying subcontractors effectively.
FAQ
1. How many offers should I collect for a construction tender?
At least three qualified offers are recommended; for complex projects, broaden the market enquiry.
2. What if an offer is unusually cheap?
Check whether all BOQ items are fully priced and mandatory criteria are met; investigate low prices on key trades to avoid later variations.
3. How do I ensure bids are comparable?
Use a uniform bill of quantities and define award criteria and weightings in advance; this enables structured comparison, including of anonymised bids.
4. What role do references play when choosing subcontractors?
References for similar type, volume and complexity of work are critical evidence of suitability and often required.
5. When is it worth automating the tendering process?
If you issue tenders regularly or frequently submit bids, process analysis and digital tools yield significant time savings and fewer errors.
