As one of our Elite Contractors, BEST Contracting has demonstrated an unparalleled commitment to quality in the roofing and industries, year after year.

BEST Contracting Services announced today that they have received a contractor “Project of the Year” award for waterproofing work done on the Tom and Billie Long Patient Care Tower, John Muir Medical Center in Walnut Creek, California. The award was made to BEST by Sika Sarnafil, the market leader worldwide in the manufacture of roofing and waterproofing systems.

John Muir Medical Center in Walnut Creek is a 324-bed acute care facility designated as the only trauma center for Contra Costa County and portions of Solano County. In spring 2011, a new $600 million addition was added to John Muir Medical Center: The Tom & Billie Long Patient Care Tower.

This new addition has been designed to promote a soothing and healing, non-institutional environment for patients with less noise, six roof gardens, a circular courtyard, plenty of natural light and a variety of environmentally-friendly elements such as a co-generation power plant, skylights, LED lighting, and low VOC flooring. A large water feature in the lobby consists of a cylindrical glass area extending to the open sky with a vegetated “island” surrounded by water and several rooftop gardens.

BEST was tasked with waterproofing many of the rooftop areas over which irrigated green (vegetated) roofs were planted and waterproofing the pond and island areas.

The project posed significant challenges. The green roofs were located on various roof levels making for difficult logistics. In addition, there were often multiple trades working in the same areas which made keeping the watertight integrity of the installation extremely difficult.

“Sika is proud to acknowledge BEST Contracting Services’ work on the Tom and Billie Long Patient Care Tower, John Muir Medical Center in Walnut Creek, California," said Jay Thomas, Sika Sarnafil Director of Marketing. "As one of our Elite Contractors, they have demonstrated an unparalleled commitment to quality in the roofing and industries, year after year."

Sika Sarnafil’s Project of the Year competition is an annual event that recognizes contractors from across the country for installations that involve superior workmanship and creative problem solving. Sika Sarnafil systems have sustainability features and benefits that are particularly advantageous in health care settings. Many of the country’s best-known health care facilities rely on Sika Sarnafil roofing and waterproofing systems.
