FairByggePris is developing an AI-powered service that helps property owners and professionals analyze contractor offers to identify errors, hidden costs, and overpriced items with unmatched speed and accuracy. Construction projects are often delayed or become more expensive because contractor offers are complex, inconsistent, and difficult to compare. Many clients – from private homeowners to housing associations and municipalities – lack the technical expertise to assess whether a bid is fair and complete. This problem is widespread: every year billions are spent on construction in Denmark alone, and a significant share of these projects suffer from budget overruns or disputes due to unclear or incomplete offers. The lack of transparency creates mistrust and unnecessary financial risk. FairByggePris applies AI to automatically analyze contractor offers. The system parses PDF or digital bids, compares them against structured industry data (such as Molio standards), and highlights missing items, hidden costs, or inflated pricing. Instead of relying on manual review by expensive consultants, users can within minutes receive a clear, data-driven analysis showing whether the bid is fair and where they should ask critical questions before signing. Over time, the system becomes smarter by learning from thousands of analyzed offers. The idea came from repeated experiences with how opaque and inconsistent contractor offers can be. Many homeowners and organizations enter construction projects without knowing if they are overpaying or missing critical details, leading to stress and unexpected costs. We started FairByggePris to give clients confidence and clarity. By using AI and structured construction data, we can finally make it easy for everyone to check their bids and avoid expensive mistakes.
