conventional fire suppression system would routinely extinguish test fires, the preparation room contains a foam emergency fire suppression system that feeds into the test room. The Fire Safety Center also has an outdoor fire testing area and a secure outdoor storage area for the heptane, a highly flammable chemical. INNOVATIVE CONCEPTS INCORPORATED “This was a very unique project,” said Rod Bagley, CVTC’s facilities director. “There were no existing facilities to study or model in the development of our design. We knew what the end result needed to be, but the challenge was figuring out how to get there.” 30-foot ceilings and 1-foot-thick prestressed concrete walls and roof with fire insulation panels in the ceiling. The room has a computer-controlled ventilation system with two large adjustable fans and adjustable vents and overhead doors to control environmental and fire behavior conditions. A viewing window allows onlookers to safely view the tests from the adjoining observation room/classroom. The building includes a staging and preparation room to assemble or refill extinguishers or other equipment before or after tests, as well as restrooms and storage areas. Because a 8│TRENDS Stephen Pederson, project manager and lead architect for Ayres Associates, said designing the building took innovation. Because of the expected heat and volume of the flames in the test room, most of the components – including thermostats, electrical wiring, plumbing, and lighting – were installed into the protective concrete or provided with a protective covering. Designers had to get variances from certain fire codes, such as those requiring installation of sprinklers and smoke detectors. The design also minimized exposed metal to limit heat reflectance and conductivity, which affects fire behavior. “From a size perspective we had to meet UL requirements for volume, while providing the dimensions to facilitate larger test assemblies and ultimately protect the building from the heat and flame,” Pederson said. “Within our design parameters – and fixed budget – we also used the most robust finishes and equipment we could find on the market, from electrical fixtures to researching exhaust systems and containment of the heat.” Robert Stone, principal at JDR Engineering, Inc., which provided mechanical and electrical design as a subconsultant, said the design was a balance of providing safety and durability for the facility and required conditions for UL fire testing. Two fans on the roof each can move up to 15,000 cubic feet per minute of air with adjustable air intake vents on the walls. A computer-controlled system ACQUISITION OFFERS CLIENTS ADDED EXPERTISE Ayres Associates recently added a fifth Wisconsin office by acquiring Frisbie Architects of River Falls, Wisconsin. The acquisition in September more than doubled Ayres’ architectural staff, and Frisbie’s River Falls office became Ayres’ 12th office nationwide. The relationship between the firms had been blossoming for some time, providing successful projects together to clients – including Chippewa Valley Technical College. During the design of the Fire Safety Center, Ayres, as a subconsultant to Frisbie, was responsible for site civil engineering services, while Frisbie provided architectural design for the project through an on-call master contract with the college. The River Falls office staff members bring a portfolio of more than 800 projects, including many that integrate sustainable design features, and our new staff members offer our clients a new depth and diversity of architectural expertise that will enhance the services Ayres can provide.

Hold the extinguisher with the nozzle pointing away from you, and release the locking mechanism. – Aim low. Point the extinguisher at the base of the fire. – Squeeze the lever slowly and evenly. – Sweep the nozzle from side-to-side. Source: National Fire Protection Association TRENDS │9
