Average and median values help compare contract sizes. Price the specific scope, quantities and contract terms rather than treating an aggregate as a budget; an undisclosed value does not mean zero.

· the playbook
How to prepare your construction bid
Read the drawings, quantities and contractual scope together. Identify site constraints, interfaces with other contractors and responsibilities for design, permits and temporary works as specified.
Build the price from quantities, productivity and the proposed sequence. Include mobilisation, site facilities, testing and handover, and make permitted assumptions or exclusions explicit.
Build a compliance matrix linking each mandatory requirement to your solution, supporting evidence and responsible colleague. Resolve conflicting documents before the deadline for clarification questions.
Scope reconciliation
Resolve differences between drawings, specifications and quantities through the tender's clarification process before pricing them inconsistently.
Site and sequence
Check access, occupied areas, utility interfaces and the critical dependencies that determine the construction programme.
Resources and partners
Show availability of key people, equipment and subcontractors, with a clear division of work and coordination responsibilities.
Quality and handover
Plan inspections, test records, defect correction and the as-built documentation required for acceptance.
Frequently asked questions
Otnox is an AI-powered procurement intelligence platform. We aggregate public tenders from 80+ markets on six continents into one dashboard, score every notice against your business profile, profile the buyers behind them, and translate everything into your working language. Built for sales teams, consultants and bid managers who sell to government.
80+ markets and counting: most of the EU (Latvia, Lithuania, Estonia, Finland, Norway, Poland, Germany, France, Spain and more), the UK, the US and Canada, Latin America (Brazil, Colombia, Chile, Mexico, Peru, Uruguay), Africa (South Africa, Kenya, Ghana, Rwanda) and Asia-Pacific (Australia, India, Indonesia, Taiwan). Every feed comes from the country's official procurement portal, and new markets are added monthly.
Minutes after publication on the official portal. We track over a million tenders with thousands of new notices arriving daily, and alert you by Telegram, Slack or email the moment something matches your profile.
You describe your business once: what you sell, where you deliver, your typical deal size. The AI scores every incoming tender from 0 to 100 against that profile, so you read the handful that matter instead of scrolling keyword noise. Matching follows the buyer as an organization too, so renamed or re-spelled entities never slip past your monitors.
A behavioral profile of every public buyer: procurement history, how often they re-tender, average contract sizes by category, repeat winners and verified contacts. You know how a buyer behaves before you spend a week on the bid.
No. One click translates any tender, and the interface itself speaks multiple languages. A Finnish tender reads like it was published in English, Italian, Romanian, Ukrainian or Dutch, and the translation is saved permanently.
Every market uses its own taxonomy: CPV in Europe, NAICS in North America, UNSPSC and national systems elsewhere. Otnox maps more than 47,000 codes into one universal category layer, so a single search covers all 80+ markets at once.
Directly from each country's official government procurement portal. No scraped aggregators, no stale mirrors. You always see the original notice with a link back to the source.
