What this market looks like
416 architecture, engineering and surveying contracts in London carry a published end date, worth £768m between them. They are held across 115 buyers, and the typical one is worth £90k.
249 of them expire within twelve months, and 78 are already inside the window where the buyer would normally be shaping the replacement. That is 60% of this market back in play inside a year.
417 different suppliers hold the work, and the three largest hold 2% of it. That is a fragmented market, which usually means no single relationship is decisive and a smaller supplier can win on merit.
10 are frameworks rather than a single contract, so part of this market is reached by getting onto a supplier list first and competing for call-offs afterwards.
The most active buyers are The Mayor and Commonalty and Citizens of the City of London (28), Clarion Housing Property Development Service Limited (25), Clarion Regeneration Limited (16).
The contracts here are most often held by Wallace Whittle Limited (5), Pick Everard (3), Tetra Tech Limited (3).
