160 King is a new 9-story commercial building which sits across from SBC Park and boasts a elegant brick façade and complementary architecture to the surrounding, fast growing South of Market corridor. It consists of five stories of office over four levels of above grade parking and one below.
Webcor was asked by the developer to analyze the project design after the original general contractor’s number rose significantly during the preconstruction phase. By introducing a structural design-build approach to the reinforced concrete structure, we were able to add 5,180 rentable square feet, seven additional parking stalls and reduce hard construction costs by over $1 million which allowed the project to move forward.
In addition, we worked with the owner and architect to incorporate a raised floor plenum into the concrete frame in order to accommodate an underfloor distribution system. This system delivers air between the structural slab and the floor instead of using ductwork in the ceiling. It provides more efficient cooling, saving as much as 10 to 15 percent on energy costs, and houses mechanical and electrical systems which allow for a more flexible use of space. We are one of a handful of contractors utilizing an underfloor plenum system for this type of project. As a key member of the Center for the Built Environment (CBE) at the University of California, Berkeley, our collaboration efforts work to advance new building technologies. We have combined our CBE research efforts on underfloor air distribution with hard dollar costs and our knowledge and experience to produce the most cost effective, energy efficient buildings possible.
