— BNBuilders has been tapped as the construction manager and general contractor on three renovation projects at the University of California San Diego totaling $17.1 million.

The projects include construction of the $2.4 million Popmintchev Laser Laboratory at Mayer Hall, an $8.7 million renovation of 14,000 square feet of biology research lab space in Muir Hall, and $6 million in renovations of the 45,000 square-foot third floor of Torrey Pines Center South for the campus information technology department.

Construction of the laser lab is particularly challenging because it involves providing space for six laser tables and cooling systems in a clean room, said Alex Pesant, BNBuilders project executive.

“On these lasers, if one piece of dust lands on it, it will break. It could be a $10,000 lens,” Pesant said.

The biology lab project involves replacing old equipment and furnishings on the first and second floors of the building.

“We’re going to basically gut the existing, dated laboratory,” Pesant said.

The work includes installing new, mobile furnishings with multiple levels of shelving and overhead utility lines to provide a clear work space which can be reconfigured to suit whatever experiments are being conducted.

The Torrey Pines Center South project includes converting a traditional office environment into an open space design with 26 conference/huddle rooms and installing a special acoustic system, Pesant said.

With offices in San Diego’s Sorrento Valley, Irvine and Seattle, BNBuilders has worked on several other projects at UCSD including fire/safety renovations to campus buildings.
