CONSTRUCTION & BIM
healthier environments for occupants, and increased environmental sustainability.
Profit drivers The adoption of BIM offers several significant advantages to investors, owners and asset managers. Our German colleagues undertook a survey of contractors who have implemented BIM. The three leading benefits it identified included the reduction of project errors and omissions; an increased collaboration with project owners and design firms; and an enhanced image of their firm among current and prospective clients.
Further research by TÜV SÜD identified additional important drivers of increased profitability resulting from the adoption of BIM technologies. In total, the six most dominant drivers include:
1. Better asset quality and usability - the BIM methodology helps to keep activities focused on KPIs as defined by the investor or asset holder, and to embed lifecycle analytics and operational metrics into the earliest stage of a project.
2. Greater project efficiency by centralising all project- related data and virtualising communication and collaboration, BIM provides all parties with continuous access to accurate and up-to-date project information. Project scheduling is more accurate and easier to monitor, supporting more efficient and streamlined processes with traceable responsibilities and visual coordination.
3.
Improved information and decision management - BIM combines virtual inspections and visualised information in a way that facilitates understanding by building owners and investors. This can dramatically reduce the number of changes and corrective actions, greatly improving the likelihood that a project will be completed on schedule and within budget.
4.
Increased transparency – the transparency of project information generated by BIM makes it easier to

identify and resolve discrepancies and errors related to design, materials, construction and documentation. Model checks about spatial, material, cost and schedule issues provide building owners and investors with increased insight into their project, allowing them to communicate more effectively with engineers and architects, thus increasing accountability. Operational safety, regulatory and legal issues are clearly documented so that asset holders have a clear understanding of all relevant matters.
5. Uprated sustainability outcomes - BIM supports the interoperation between architects, engineers, auditors and facility managers in evaluating multiple energy usage scenarios in the context of other project requirements, and to adjust construction specifications and materials to maximise natural resource efficiencies. This can result in reduced operating expenses as well as a higher asset value (e.g. by supporting a higher level of sustainability certification).
6. Overall operational excellence - BIM models can serve as an object-related database for systems that allow data from actual operations to be fed into and out of the BIM model. This allows for further BIM model refinement and modifications to lifecycle management practices, and generates updated performance benchmarks.
Despite its potential to improve results, many are still hesitant to embrace BIM. Much of this comes down to uncertainty about using the methodology, as BIM implementation requires a fundamental rethink of the way of working. It is therefore important to note that these key benefits will only be achieved when the BIM methodology is properly implemented and executed in the three dimensions of strategy, tactics and operation throughout a project’s entire lifecycle.
