Sierra College Grass Valley Campus Expansion

Holdrege & Kull provided environmental engineering, seismic hazard evaluation, geotechnical investigation and design, and construction quality assurance services during both Phase I of the expansion, completed in 2009, and Phase II of the expansion, completed in 2011. Phase I broke ground in 2008 and included construction of 43,000 square feet of additional classroom buildings, a performing arts center, health and fitness center, student service and administration buildings, and a public safety training facility. Phase II of the 105-acre campus expansion included 20,300 square feet of new construction, including a new multi-purpose building, a gymnasium, wellness center, and a corporation yard. Appurtenant construction included underground utilities, drainage and infiltration systems, and asphalt concrete paved parking areas and roadways.

H&K’s environmental work on this project included Phase I and Phase II environmental site assessments associated with a Mitigated Negative Declaration. Recognized environmental conditions included past waste management practices, lumber drying, and agricultural pesticide application.

H&K’s construction quality assurance services included review of plans and specifications; special inspection of engineered fill, masonry, and structural steel; and field sampling and testing of concrete and reinforcement. At the construction manager’s request, daily field reports and correspondence were uploaded to Constructware, a web-based construction management tool.
