Roof hatches provide reliable access atop a new skyscraper.
Hotel construction has soared in Seattle in recent years, including the opening of the Hyatt Regency Seattle in 2018.The $470 million project includes 1,260 guest rooms, 45 floors, and 1.4 million square feet. The hotel is the largest in thePacific Northwest.
Developer Richard Hedreen purchased the three-quarter block, L-shaped parcel in 1995. The project faced an unusual number of hurdles, including the city’s design-review process. The site needed to be reviewed as a possible historical landmark, and some tenants in apartments on the block where the hotel was built required relocation assistance.
Designed by LMN Architects, the project closely resembles the original vision. “We wanted to create a visitor experience that was authentic to the ethos of Seattle, allowing guests to be immersed in the culture of the Pacific Northwest,” said Stephen Van Dyck, Design Partner for LMN Architects.
The hotel received LEED Gold certification, the second-highest building rating in the world, and is the only LEED Gold-certified hotel in Seattle.
Environment-friendly measures included installing a light-colored roof to reduce the urban heat-island effect, and incorporating a highly-efficient laundry system that captures both heat and water after use to reduce the need for additional energy to preheat incoming water to the laundry system.
Construction teams also designed mechanical and lighting systems that reduce the building’s energy usage, uses waste heat from the chiller to heat hotel spaces and incorporates recycled content in more than 20 percent of the products used in its construction.
“Building sustainability is a strong core value of ours,” said Shauna Decker, Vice President of Design & Development for Hedreen. “Frankly, in order to represent Seattle appropriately, we had to make the commitment early to achieving LEED Gold for the Hyatt Regency Seattle.”
The project includes four roof hatches manufactured by The BILCO Company. The roof hatches provide reliable roof access and are equipped with snow sensors, motorized operation and safety railing systems. Two hatches measure 3-ft., 2-in. × 12-ft., and the others are 3-ft., 2-in. × 14-ft. The custom-built hatches include compression spring operators for lift assistance and an automatic hold-open arm with grip handle release. They are also manufactured with corrosion-resistant materials. The curb features the Bil-Clip flashing system, an innovative method to quickly and easily secure single-ply roofing to the hatch.
The hatches required customization to be used on the roof of the hotel, which sits on an unusually shaped, narrow parcel in downtown Seattle. The units were equipped with motorized operation to facilitate opening and closing in the city’s notoriously damp climate.
LMN Architects had been knowledgeable about BILCO from work on previous projects, according to Lisa Stevens of GVA Northwest, which procured the hatches for RC Building Specialties. “BILCO’s reputation as an industry leader and the company’s ability to accommodate the sizes needed in a timely matter were almost assuredly important factors for LMN,’’ Stevens said.
