Stanley Mosk Library and Courts Renovation

Project overview

Vanir served as the construction manager for the renovation of the 1928 Stanley Mosk Library and Courts Building – a registered federal and state landmark and one of the nation’s most historically significant government buildings. The project included fire and life safety upgrades, infrastructure improvements and the rehabilitation of historical architectural elements. Deficiencies in mechanical, electrical and plumbing systems were corrected, enabling the reopening of historic light wells that had been covered for over 40 years. In addition, exterior elements including the roof, facade and historic windows were repaired. The renovation was completed within the critical tenant-driven schedule and under budget by $14 million.

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 implementing an insulated and reflective roof, high-efficiency pumps and motors, low-emissivity film on glass windows, upgrades to 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 through a collaborative effort.
