Hearst Castle Neptune Pool Renovation

RESTORING A HISTORIC LANDMARK

The iconic Neptune Pool at Hearst Castle in San Simeon, California embarked on a complete restoration project nearly three years ago. The restoration and renovation project included completely draining the pool, carefully removing and storing the ancient statues that adorned the perimeter of the pool, removing all of the old tile, finding and repairing leaks in the system, sealing the concrete shell, updating the filtration, piping and flow systems, adding waterproofing, resurfacing the pool and installing about 10,000 replica white marble tiles and 4,500 green serpentine tile pieces. Dozens of different industry experts were included in this project to preserve the historical accuracy, restore the artifacts, and integrate modern plumbing systems into a historical pool.

In order to obtain a close to identical match of the original green marble tiles in the pool, they purchased new green marble tiles from the exact same location where the original tiles were purchased nearly 100 years ago – a stonework quarry in Vermont. However, due to the color and the historic nature of the material, there was NOA (naturally occurring asbestos) in the tiles and this is where A-Tech Consulting was retained for occupational and environmental exposure compliance for asbestos related work activities.

PROJECT OVERSIGHT

A-Tech Consulting was hired to train skilled tile workers how to work with NOA, properly use personal protective equipment, properly assemble and utilize a containment and institute proper engineering controls. A-Tech Certified Asbestos Consultants and Technicians, conducted personal monitoring for the contractors who were doing the green marble tile cutting for the Neptune Pool. A-Tech was hired to conduct oversite to ensure the contractors and general public were not exposed to any asbestos fiber concentration above the Permissible Exposure Limit (PEL). We conducted personal air monitoring, using PCM cassettes attached to the workers suit as they were filing and shaping the green marble tiles. Additionally, we conducted daily air monitoring around the entire work site. There was a lot of technical logistics throughout the phases of the project that our expert staff was able to create cost and time efficient solutions for. This project will be a company favorite; being trusted with such a sensitive and complex project as a participant in a historical project in a beautiful location in the Central Coast is a huge testament to expertise and responsiveness of our team.
