BIM: Hacking Hackitt

Niraj Mistry, Head of BIM (Stroma Certification) & Upskilling Stream Lead (UK BIM Alliance), decodes the ‘Hackitt Report’ and extracts the use of Building Information Modelling (BIM). Niraj explains how BIM can be used to mitigate risks in the construction and management of assets by using digital asset information.

“Building a Safer Future Independent Review of Building Regulations and Fire Safety: Final Report, Dame Judith Hackitt DBE FREng, May 2018”, describes how the regulatory system for high-rise and complex buildings was not fit for purpose.

“The ideas produced in this report have broader application to a wider range of buildings and to drive change more broadly.”

The report identifies key issue underpinning the system failure:

BIM: Hacking Hackitt
  • Ignorance – we need to raise awareness of regulations and guidance and improve our understanding
  • Indifference – we need to have duty of care, stop cutting corners and over value engineering. We need to prioritise safety. You could be living there
  • Lack of clarity on roles and responsibilities – we need to clearly define responsibility and be accountable for our work
  • Inadequate regulatory oversight and enforcement tools – we need a compliance framework in place

Create a secure record of digital asset information

“Recommendation 8.1:

  1. Government should mandate a digital (by default) standard of record-keeping for the design, construction and during the occupation of new HRRBs. This is to include any subsequent refurbishments within those buildings.
  2. Digital records are to be in a format which is appropriately open and non-proprietary with proportionate security controls.”

BIM provides a digital record of a project at the handover stage. A digital asset information model (AIM) contains the 3D model, documents and information. This is the product of PAS 1192-2 (Capex) and PAS 1192-3 (Opex). As for the security controls, PAS 1192-5 does talk about this subject?

Using the Asset Information Requirements (AIR)

“Recommendation 8.2 Government should work with industry to agree what information must be held in the digital record for new HRRBs.”

Before we get to an AIM, we need asset information requirements (AIR). This recommendation helps to provide a platform for information to be put into the AIM. This is a call for Clients, Employers, Asset Owners and Developers to recall a motto of BIM: ‘start with the end in mind’. Thus, if you want safety provision, incept the need for the required information at the start.

A safer future

The report provides principles for a new regulatory framework, emphasising the need for a “clear model of risk ownership”. It tells us that we need to “begin thinking about building as a system” and must take a “risk-based approach” and have “transparency of information and an audit trail”.

An efficient system is built on processes taking place. In summary, BIM provides an ideal platform for the flow and storage of information. At the back end, the information can be retrievable for the variety of uses required.

“For these benefits to be realised, there needs to be wider adoption by industry and the supply chain, requiring parties to be bought into the approach and recognise the benefit…embracing BIM in an open, consistent and transferable way is essential to achieving this.” – BIM4Housing Steering Group
