‘From the author’s perspective, best practice indicates that it is the business objectives that should decide how BIM technology and processes develop.’
Future opportunities Within design and construction sectors of the Australian healthcare industry, there is a growing momentum around the awareness of the opportunities associated with BIM. Now that BIM technologies are becoming more commonly applied in construction, there is some data starting to be exchanged at project handover. This is allowing asset and facilities managers to engage in the process. There are owner/operators now asking for BIM deliverables and thus expecting a collaborative process centered on a coordinated and federated BIM model and process.
Healthcare facilities are inherently
complex by nature. As stated previously, they IFHE DIGEST 2014

are service-heavy structures – with many mechanical, electrical and hydraulic systems – and then there are the resultant complexities in ever-developing models of care which could result in internal re-designs and new fit-outs every five to ten years. The base-building component will often last a lot longer than the internal (fit-out) elements. When a design goes through a
collaborative process all design decisions can be considered together. According to Sir Ove Arup (1970) ‘the term ‘Total Architecture’ implies that all relevant design decisions have
been considered together… integrated into a whole by a well organised team empowered to fix priorities.’6
With the use of BIM
technologies there is the ability to streamline approvals and engagement processes through the ability to visualise in 3D, but also reduce risk in the construction period (where costs and time escalate). Figure 4 is an example of how stakeholder engagement can be enhanced and streamlined through the use of accurate 3D graphical visualisation that accurately reflects the finished product.
