Stanley Mosk Library and Courts Renovation

Project overview

A registered federal and state landmark, the 1928 Stanley Mosk Library and Courts Building is one of the nation’s most historically significant government buildings. Vanir served as the construction manager for the renovation of the facility, which consisted of fire and life safety upgrades, infrastructure improvements and rehabilitation of historical architectural elements. Deficiencies in mechanical, electrical and plumbing systems were corrected, allowing historic light wells that had been covered for 40+ years to be opened. Exterior elements including the roof, facade and historic windows were repaired. The renovation was completed within the critical tenant-driven schedule and $14 million under budget.

Vanir led green building and historical preservation efforts

Obtaining LEED Silver certification was one of our client’s main goals. Factors contributing to the rating included an insulated, reflective roof; high efficiency pumps and motors; low-emissivity film on glass windows; upgrades to the HVAC and plumbing systems; and modifications to the irrigation system.

Protecting the many art and architectural treasures in the building also required creative solutions. From designing and building humidity control censors for the murals, to cataloging and relocating 35 shelving-miles of books, challenges were overcome with a collaborative effort.
