Rudolph and Sletten

Rudolph and Sletten is a California-based general contractor that has built much of Silicon Valley's physical fabric - from Apple Park and Lucasfilm's Skywalker Ranch to hospitals, research labs and university campuses. Founded in 1959 in a Los Altos garage, the firm pioneered guaranteed-maximum-price, fast-track delivery and grew into one of the West Coast's largest builders of technically complex healthcare, life-sciences and education projects. Now a subsidiary of Tutor Perini, it employs roughly 740 people and reports about $307 million in annual revenue.
