2.3 2. PwC Introductory note to BMM

We're presenting an introductory note on BIM Level 2 Benefits Measurement, focusing on the approach and benefits framework. This document, finalized in March 2018, aims to clarify how we developed our Building Information Modelling (BIM) Level 2 Benefits Measurement Methodology (BMM) and the underlying benefits framework. We'll also delve into the principles supporting our BMM and how they should be applied when practically measuring benefits. The rest of this note details the context for our work, including BIM Level 2's role in achieving the objectives of the UK Government Construction Strategy. We'll explain our approach to developing the benefits framework and the BMM, and describe the framework itself, covering the scope of the benefits we consider and their dimensions. Additionally, we’ll outline the key principles that underpin our proposed approach to measuring the benefits and the practical implications of these principles for assessing the benefits of BIM Level 2. Finally, we will consider some practical aspects for measuring benefits. Our aim is to shed light on the background and context of our methodology for measuring the benefits of applying BIM Level 2. We'll also examine the vision for BIM in addressing problems in the construction sector, as outlined in the Government Construction Strategy. Furthermore, we’ll discuss the progress and challenges toward BIM Level 2 implementation and how our work contributes to addressing these challenges. This note also provides a definition of BIM Level 2 and BIM maturity, explaining how this relates to our benefits framework. The construction sector is a significant area for the UK economy, and central to the industry's bigger picture – as stated in the Government Construction Strategy (GCS) published in 2011, the construction sector represents some 7% of GDP or £110bn per annum of expenditure – with 40% of this being in the public sector. Government construction clients do not always fully realize the benefits from public sector construction. The 2011 GCS states that “the UK does not get full value from public sector construction” and that it has failed to exploit the potential for public procurement of construction and infrastructure projects to drive growth. As a consequence, there has been a push from the Government to make the public sector a better, more intelligent client, which gains better value from construction. The 2011 GCS sets out 13 integrated objectives seeking to encourage change in the relationship between public authorities and the construction industry – one of which focuses on the implementation of BIM. BIM Level 2 was mandated as a minimum requirement on all centrally-procured public projects from April 2016. The Cabinet Office is coordinating the Government's drive to the development of standards enabling all members of the supply chain to work collaboratively through Building Information Progress, and “Government will require fully collaborative 3D BIM (with all project and asset information, documentation and data being electronic) as a minimum by 2016.” The GCS ambition is to foster improved central government's capability as a construction client. It states the aim to “embed and increase the use of digital technology, including Building Information Modeling (BIM) Level 2”, and deploy collaborative procurement techniques. It also includes the objective to “enable and drive whole-life approaches to cost and carbon reduction across the construction, operation and maintenance of public sector buildings and infrastructure.” BIM Level 2 has been mandated by UK Government because information rich BIM technologies, processes and collaborative behaviors have the potential to unlock new and more efficient ways of working, and produce better and more consistent outcomes at all stages of the asset lifecycle.
