How contractors track opportunities today, and what it costs
Tender notices arrive by email and word of mouth, get noted in an engineer's diary, and are priced in a spreadsheet that lives on one laptop. The system holds until three bids close in the same week.
The cost is unusual in this trade because it is concentrated. A missed submission is a total loss of effort already spent, and a bid priced without a site visit can cost far more than losing it would have.
