SKANSKA USA have worked in a building information modelling (BIM) environment to optimise the design of the new Life Sciences Building at the University
of Washington in Seattle.
The building, due for completion later this year, comprises 187,000 square feet (17,400 square metres) of lab space including 20,000 square metres (1,900 square feet) of new greenhouses.

According to Skanska’s senior project manager Kirk Brewer, information modelling proved essential in engineering the building, particularly in terms of spatial co-ordination within the federated graphical model.
If the building had been designed using standard procedures, the complex would be 13 feet taller than permitted.
Laboratories usually require a generous ceiling height for mechanical services, such as cooling and ventilation, to ensure a constant environment for experiments.

Chilled beams turned out to be a solution which could deliver both a well-tempered environment and shrink the ceiling space.
This resulted in other services being more densely-packed than usual, but by co-ordinating in a federated 3D environment during the design process and by zoning mechanical systems, engineers were able to deliver the plan within its limitations.

Both the contractor and client benefitted from the cost and schedule certainty that information modelling brought to the project delivery process, and the 3D model made it possible for the client to see the space before it was built, pushing changes where necessary.

A host of sustainability features were incorporated into the new building, including shading fins coated with translucent solar cells, which will generate enough power to light the building, as well as the adjoining greenhouse using recycled wastewater for irrigation.
