Project: Oakland Airport Connector - Doolittle BART Station in Oakland, Calif.
Architect: ED2 International
Glazing Contractor: Bagatelos Glass
Products: SuperLite II-XL 60 IGU in GPX Framing with Sunshade Connection
Why it’s unique: Sunshade connections are not typical with fire rated assemblies
For the Doolittle Maintenance Facility, SAFTI FIRST provided 60 minute, fire resistive wall openings in the exterior using SuperLite II-XL 60 insulated with low-e glazing in GPX Framing with a clear anodized finish. SAFTI FIRST engineered a connection that allows the structural elements of the GPX Framing System to support an integral sunshade system, instead of being hung in front of it.
The framing covers were notched around the brackets to create a seamless connection. The connection was also kept in front of the waterline to avoid a potential breach, keeping the system air and water tight. Other manufacturers would have to go through and behind the glazing pocket to get to the structure, creating a challenge during the fabrication and installation phases.
The potential for water penetration increases significantly once you punch a hole in your framing and glazing pocket. By using the SuperLite II-XL 60 IGU in GPX Framing, the architect was able to achieve the aesthetic and code requirements of the application while keeping the whole system air and water tight.
The Doolittle Bart Station is one of the first installations of the GPX System with sunshade connections, which also include SLCC New Instruction and Administrative Building in Salt Lake City, UT. While it is a fairly new offering, it is quickly gaining attention and interest in the building community. Sunshades are commonly used in building to control the amount of direct sunlight through exterior windows.
When the location of the exterior windows also need to meet fire rated requirements due to property lines, etc., it is good for designers to know that they have an option that combines both.

Architect Zaha Hadid is in high demand these days, designing projects in Hong Kong, Milan, and Seoul, not to mention the London Aquatics Center, the swimming arena for the 2012 Olympics. But one of the firm’s smaller clients, the city of Elk Grove, Calif., recently conjured far different kinds of aquatic life when members of the City Council and the public chose words like “squid,” “octopus,” and “starfish” to describe the latest renderings for a proposed civic center.

Are architects falling behind on BIM?
A study by the National Building Specification arm of RIBA Enterprises showed that 43% of architects and others in the industry had still not heard of BIM, let alone started using it. It also found that of the 13% of respondents who were using BIM only a third thought they would be using it for most of their projects in a year’s time.
