CONSTRUCTION & BIM
IN IT TO BIM IT
Dave Peacock, Technical Director of TÜV SÜD Building Advisory Service, analyses how BIM improves profitability for building owners.
Construction projects are more complex than ever, as state-of-the-art materials and technologies are integrated into buildings to increase usability, optimise resources and promote sustainability.
Building Information Modelling (BIM) can significantly increase efficiency and reduce construction costs during the planning, design and execution process. Intelligent BIM is not just a new level of design documentation but is the ‘digital backbone’ of the physical asset that supports the monitoring, management and optimisation of the construction cycle. BIM has revolutionised the construction industry as issues can be identified and resolved before construction begins at site level. This mitigates risks associated with time and cost due to waste materials and abortive time on site, whilst delivering environmentally sustainable buildings.
Governments around the world also recognise the value of BIM technologies, as many either require or encourage the adoption of BIM in government-funded construction projects. For example, in the United Kingdom the use of BIM in public projects became mandatory in 2016. Since 2006, the U.S. General Services Administration (GSA) has required that new buildings designed on behalf of the agency’s Public Buildings Service use BIM at least in the project design stage. In Singapore, the country’s Building and Construction Authority (BCA) implemented the world’s first BIM electronic submission system for regulatory approval of building projects in 2008.
BIM standardisation ISO 19650 is an international standard for managing information over the whole life cycle of a built asset

using BIM. It contains all the same principles and high- level requirements as the UK BIM Framework and is closely aligned with the old UK 1192 standards. The UK BIM Framework provides an overarching approach to implementing BIM in the UK, developed by BSI, CDBB and the UK BIM Alliance. ISO 19650 represents a significant step forward in standardising information management requirements on projects using BIM within an internationally agreed set of concepts and principles.
BIM benefits Major building construction projects are expensive and highly complex, involving multiple parties, thousands of personnel and many years. They can therefore be fraught with challenges, typically resulting in project delays, cost- overruns and other setbacks that ultimately compromise ROI. BIM helps to minimise these risks by creating a multi- dimensional digital representation of a project’s physical and functional characteristics. This includes scheduling, costs and facility management data, alongside operation phase KPIs and ROI analysis. These multiple data dimensions are maintained as a single ‘source-of-truth’ - changes made to any project element trigger updates to related elements.
BIM facilitates the effective management of an infrastructure project throughout the entire lifecycle. The immediate identification of potential conflicts during the design phase means that they can be addressed well before construction commences. It also enables the creation of multiple ‘what-if’ scenarios to evaluate alternative approaches - enabling active collaboration. It can also contribute to the realisation of larger project goals, such as improved energy efficiency,
