Provisional sums are where projects lose money quietly.
They sit in the BoQ as placeholders — reasonable at tender, rarely revisited until they're instructed. By then, the original assumption has no documentation behind it, the subcontractor has priced something different, and the gap between the two becomes a variation the commercial team has to fight. Most provisional sums expand because the scope behind them was never properly defined in the first place.
EchoByld identifies every provisional sum in your tender documents and traces what the drawings and spec actually say about that scope — so you go into contract knowing what's solid and what's exposed.
