HEALTHCARE BIM DESIGN
Embedding data into building objects improves consistency and automation of information
BENEFITS OF BIM TO THE MEP CONSULTANT
Quicker to produce documentation
Automated area / volume schedules
Calculations added to spaces and to equipment
Understanding space limitations
Changes can be incorporated quicker
Dynamic link between drawings and equipment schedules
This is the aspiration for the ward block. By bridging the gap between design and operation, there is an opportunity for users and designers to improve their understanding of how buildings can be operated more efficiently, offering potentially large energy savings. The NHS is keen to drive the reduction
of waste in construction and building management. It has its own targets as well as BREEAM and other government targets (See ‘Advice for NHS Trusts as construction clients’, Waste and Resources Action Programme, March 2010). The ward block took advantage of prefabrication wherever possible, and fabrication details were taken from the designers’ BIM models. Structural and architectural modules were taken directly from the designers’ models; whereas prefabricated MEP modules were taken from the installation model. Hoare Lea is now working with Crown
House to streamline the transfer of models from consultant to installer, as this is seen as an opportunity to save time and cost during production stages. The project was delivered using Procure
21, which promotes collaborative working and continuous improvement through early stage contractor appointment. Having contractor and installer involvement through the early design stages of a BIM project enables the team to consider fabrication requirements as the design model is being created; thus reducing the

need for reworking after detailed design that occurs on a traditional project. Early contractor involvement is very important for successful BIM implementation whatever the sector. The use of PFI or LIFT procurement
means that construction teams are often also responsible for energy management during occupancy. As with early contractor involvement, having input from building operators from the outset enables greater understanding of building use and BIM’s potential for FM and building management. This will be important for all PFI procured projects and will enable the facility manager to understand maintenance requirements and the design intent of installed
systems.These procurement routes are more suitable for collaborative BIM projects than the traditional design-and-tender process. This was Hoare Lea’s first fully collaborative BIM project and we found it a positive experience. We are delivering further BIM projects in healthcare and other sectors, and developing our knowledge and capabilities to the next level. Despite a steep learning curve, benefits outweighed problems and we delivered the project successfully. As MEP consultants, we have been able to take advantage of many efficiency improvements in order to offset the effects of the learning curve, even on our first project.
