Flying H Hangar

Project Description

The aircraft storage hangar was designed to provide superior thermal performance and
sustainability compared to conventional manufactured metal framed hangars of similar size. The hangar is 100ft x 100ft, with 30ft tall side walls. Structural insulated panel (SIPs) construction was utilized for the walls and roof. The SIP roof panels are supported with steel open-web bar joists. Both the roof joists and SIP walls are supported by glued-laminated timber columns. The layout of SIP supports was intended to greatly reduce panel manufacturing waste and use the largest size panel pieces. Most panel sizes utilized were 8ft wide x 24ft long, corresponding to the SIP panel manufacturing dimensional limits. The SIP manufacturer exclaimed that they have never done such a large SIP building with such little waste.

The lateral force resisting system is comprised of SIP shear walls on three sides, with a steel truss moment frame at the hangar door endwall. The endwall was designed to accommodate a 90ft wide x 27ft tall pivoting hydraulic hangar door.

Central Elementary School

Project Description

As a subconsultant to SMA Architects, RPA provided civil, site and landscape design services for the new Central Elementary School in Helena, Montana. The site posed significant grading challenges, due to an elevation change of nearly 30 feet across the 3-acre site. The design team incorporated site walls and variable building finished floor elevations to ensure usable and accessible exterior spaces. Construction of the new school was completed in August 2019, in time for the 2019- 2020 school year.
