Tender patterns: Where construction tenders go wrong
Six free one-page notes on where construction tenders most often go wrong, one for each role on the bid team.

Key takeaways
Six one-page notes, one for each role on the bid team.
Seven checks per role, before problems reach the price.
Built on problems that recur across tenders, not one-off mistakes.
Tender patterns is a series of six free one-page notes from Volve on where construction tenders most often go wrong. Each note covers seven recurring problems for one role on the bid team, and what to check before they reach the price.
The series is organised by reader because the same tender breaks in different places depending on who is looking at it. The estimator meets the problem as a quantity that doesn’t match. The commercial lead meets it as a clause that moved risk. The project manager meets it months later as an assumption that never reached site.
The six notes
