Interface matrix
Clarify scope boundaries before they become variations.
Tenderhub searches BoQs, contracts, performance specifications and drawings for responsibilities between trades, creating a matrix with source, owner and open interfaces.
Why this workflow matters
Unclear responsibility is often priced twice—or not at all
Connections, builder’s work, fixings, openings and commissioning often sit between trades. When tender documents do not assign them clearly, both pricing and delivery carry risk.
