Element 28
Scope/Solutions
Prominently heading off the downtown Bethesda intersection at 100 Commerce Lane, Element 28 brings more than 100 rental units and ground-level retail to the neighborhood. Residents can access many amenities, including private balconies, landscaped plazas, a fitness studio, and a rooftop deck with a retractable glass wall at the indoor/outdoor clubroom. SGH consulted on the building enclosure for the fifteen-story, mixed-use building clad with a red-glazed terra cotta and glass fiber-reinforced concrete rainscreen.
SGH consulted on the design of below-grade, wall, and balcony waterproofing; window and curtain wall systems; rainscreen cladding assemblies; and roofing. Highlights of our work include:
- Reviewing the proposed enclosure design, focusing on design efficiency, performance, and constructability, and developing details to integrate the various systems
- Helping develop and coordinate waterproofing, drainage and thermal barriers at complex plaza and rooftop amenity spaces, such as the art installation, stair enclosure, rain ladder, and intensive bioretention feature
- Consulting on the structural glass feature at the building entrance vestibule, including its integration with adjacent roofing, cladding, and plaza waterproofing systems
- Performing hygrothermal and thermal analysis to evaluate moisture transmission in proposed wall and roof assemblies
- Evaluating enclosure system products and materials for conformance with performance expectations and service life
- Reviewing on-site mockups and quality control testing of window and roofing systems
- Performing construction phase services, including reviewing submittals, visiting the site to compare the constructed work with the design intent, and helping respond to contractor questions and address field conditions
