The Cookham Wood, HMP Berwyn and Five Wells projects were supported by multi-party framework alliances that had been credited in the 2012 Effectiveness of Frameworks Report with achieving reduced operating costs of £10 million, reduced burden on industry of £30 million and procurement risk mitigation of £2 million.
The Cookham Wood and HMP Berwyn Trial Project case studies showed how strategic ESI combined with the integrated use of BIM and MMC helped project teams to achieve efficiency savings of up to 26%, reduced construction programmes, design innovations and more sustainable project solutions, appointment of local and regional supply chain members and new local skills and employment opportunities. Comparable achievements are being demonstrated on the Five Wells project which is a Construction Playbook case study.
HMP Berwyn is one of the largest prisons in Europe and its team included Lendlease, AECOM, Sweett Group, WYG, Capita Symonds, TPC Consulting, Hoare Lea and Crown House who worked together during a 38-week preconstruction period to develop ESI contributions to design, risk management and the finalisation of agreed costs. MoJ applied lessons learned from the Cookham Wood Trial Project which enabled additional benefits from BIM and greater ESI contributions from tier 2 and 3 supply chain members, including a specific focus on local and regional SMEs.
From a budget of £212 million, the team agreed innovations and efficiency improvements that led to a fixed price of £157 million without eroding the quality or function of the project. These included:
■ A reduced footprint for the Entry Building/ Energy Centre, using lessons learned from the MoJ framework's Oakwood Prison project and from consultation with operational colleagues
■ Challenging the original costed design to incorporate an open 'swale' in place of an attenuation tank, creating a new environment for wildlife while reducing construction costs
■ Value engineering of the mechanical and electrical solution, leading to adoption of alternative cheaper lighting solutions previously used on MoJ framework projects in Scotland and now used throughout the MoJ estate.
The co-located team overcame significant challenges caused by asbestos, soft ground conditions and the remains of an old munitions factory. It also reworked the construction programme to avoid delays caused by a General Election, and managed shortages in precast through sourcing from multiple European manufacturers.
