The four-year deal will replace a patchwork of one-off tenders with a new multi-supplier arrangement split between general highways schemes and structures/geotechnical works.
Call-off contracts will range from £500k to £10m, with the council aiming to streamline delivery of major roads projects and cut procurement times.
Firms are being asked to feed back on the proposed setup before a formal tender is issued.
Key points under consideration include the use of NEC4 contracts, a 70:30 quality/price split at framework level and 30:70 at call-off stage, and social value scoring via the Social Value Portal.
Lot 1 covers highways schemes from £500k–£10m; Lot 2 targets structural and geotechnical jobs from £250k–£10m.
The new arrangement will come into force at the start of 2026.
Interested contractors have until 5 August to respond to the market engagement questions.
