HM Young Offenders Institute Cookham Wood, a key custodial establishment for the South East, was the first public sector scheme to be executed using BIM. Faithful+Gould was the client’s representative, working on behalf of the Ministry of Justice (MoJ) to manage the successful project outcome.
The use of BIM has enabled this project, and those in the pipeline, to be built with an optimal design, construction and operating solution, minimising waste and reinforcing the MoJ’s 'lean programming' philosophy and implementation.
For the Ministry of Justice, the BIM process has initiated information for a library of standard components and associated COBie data which will be used on future MoJ projects; it has facilitated and informed the decision making process and has provided a single central resource of essential data for use throughout the entire building lifecycle. The data and model outcomes will be used to ensure optimal asset performance enabling the MoJ to explore and closely monitor their asset usage: how the systems are operating, and when and why they need maintaining. Modelling for better user outcomes, with the ability to feed this data back to inform future projects, underpins the real client value proposition.
As this was the first government project in the UK to be tendered and delivered using BIM, Faithful+Gould was responsible for working with the Government's BIM advisors in drawing up tender documents and contract documents to incorporate this fast developing technology. These documents laid industry foundation stones for the use of BIM on projects, and the information produced and the lessons learnt have been fed into PAS 1192:2 and the CIC BIM Protocol recently published.
Faithful+Gould was responsible for ensuring that the tender and contract documents exactly reflected what the client required from the constructors with regard to BIM. To this end we helped to draw up BIM client requirements documentation enabling the project to go to tender two weeks earlier than planned in March 2012. We facilitated constructor briefing sessions during the tender period to ensure that these requirements were fully understood by all tenderers, and we evaluated the tender responses using the BIM Evaluation Protocols agreed. Interserve was the winning constructor, and work started on site with an Enabling works package in August 2012, followed by main works commencing in August 2012. The project achieved practical completion in January 2014.
Our role included devising project programmes encompassing the BIM processes, and enabling the client and design teams to better understand how the BIM interfaces and deliverables tied in with the ‘traditional’ project processes. We have taken this first project through each project and BIM stage, providing ‘lessons learned’ evaluation after each stage for our client, in order that processes can be improved going forward.
In line with the Government's Construction Strategy, the Ministry of Justice targeted 20% savings on this project, and this was achieved, driving down the cost per square metre from £2,910 to £2,332. The resultant cost savings were a result of favourable market conditions, collaboration through the supply chain giving innovative construction solutions, and BIM facilitating early clarity on outcomes and fully co-ordinated design between disciplines, obviating the need for late and costly changes.
