• Plan for about 35 days to prepare a bid — that is the median gap between publication and deadline across 15 of their tenders.
• They publish about 2.0 tenders a month, measured over 46 months of history.
• Half of the tenders where they publish a value are estimated at £21.8m or less.
• Most of their buying falls in construction work, architectural, construction, engineering and inspection services, business services: law, marketing, consulting, recruitment, printing, security.
