The new building framework is being carved up into four value bands and covers Merseyside, Greater Manchester, Cheshire, Lancashire and Cumbria.
The Liverpool-based private procurement group promises a work pipeline of £2bn up to 2022, targetting education, blue light, council and health care building projects.
It plans to issue an invitation to tender on 19 March with tender documents due back on 30 April for awards on 1 June.
Up to eight contractors will be named for each of the four value bands – £1m-£5m, £5m-£15m, £15m-£25m, and £25m+ – with contractors being limited to two wins.
Framework partners will be performance managed around 10 KPIs, which include safety, fair payment, and their ability to deliver to programme and budget in both pre-construction and construction phases.
A supplementary Procure North West (Consult) Framework is due to come to market in the autumn, which will provide a procurement route for public sector bodies to appoint designers, project managers, and cost consultants.
