This project consisted of a 30,000-square-foot expansion of the existing Charles M. Schulz Sonoma County Airport terminal, as well as the renovation of 8,500 square feet within the existing terminal building. The new terminal was built to increase the facility’s ability to meet passenger demands.
The roof of the new terminal building is constructed of cross-laminated timber (CLT) panels to allow for simplified installation and connections while meeting structural performance objectives and architectural design criteria. Initially, the team considered using steel joist framing at the roofs, but ZFA suggested using CLT panels over a glulam/steel truss system to realize the benefits of CLT. After design and pricing iterations, the design and construction teams were in favor of the CLT design. The ability to crane the roof structure in from above and enclose it within a few days streamlined the construction schedule. The architect incorporated the 20-foot-long CLT spans into the design, which allowed greater spacing between trusses and fewer column lines. The standing seam metal roof and insulation are located above the panels, leaving the CLT exposed from below.
