Block 106, Lot A is a 3-story mixed use Type V building located in the Mill District, and is
currently under construction. The building is 17,600 SF with 4,000 SF of at grade parking beneath the building. The ground floor is intended for retail and office space with levels 2 and 3 serving as multi-family residential units. The structure is a combination of steel and wood framing. Wood shear walls serve as the lateral force resisting system for the building. The building is configured with a 2,000 SF courtyard at the 2nd level. The courtyard was designed for a 605 SF landscaped roof garden and snow storage.
RPA served as the Civil and Structural Engineer of Record for this project. Additionally, RPA’s
structural group provided special inspection services during construction
RPA partnered with High Plains Architects to design a new 8,640 SF, single-story medical office building. The superstructure system consisted of exposed open web, parallel chord hybrid roof truss, comprised of wood and metal, supported on steel and wood framing. Rammed aggregate pier foundations were employed beneath the building to mitigate highly compressible subgrade soils. A network of cast-in-place concrete grade beams were utilized to transfer superstructure loads to the pier foundation. Careful planning and collaboration with the architect was undertaken to ensure interior demising walls, which were framed to the underside of roof sheathing, were detailed to allow deflection of the roof trusses and maintain rigorous sound isolation between exam rooms and offices.
RPA partnered with Aero-Graphics to complete a LiDAR project to provide mapping and aerial photography for a 32-mile square area in and around Virginia City, Montana. Aero-Graphics
requested RPA to set 10+ targets, including 2 porous targets for their work. RPA was able to set and control the project in time for a late notice fight operation (weather delays) and was able to provide continuous GPS ground control for flight operations.
Working with Mosaic Architecture, the project included design and construction of a new 12,000 square foot clinic building. The new facility, located at the intersection of Montana Avenue and 11th Avenue in Helena, houses both an optometry clinic and retail showroom.
Site design included challenges associated with keeping the existing clinic building in service, while the new facility was being constructed. In addition to a fully accessible site design, the new facility includes 10,000 gallons of underground stormwater detention/retention, located directly underneath the new 38-stall paved parking lot. The underground facility is constructed of aluminized corrugated steel piping, with perforations to allow stormwater runoff to infiltrate on-site.
KEY PROJECT ELEMENTS
- New 38-Stall Paved Parking Lot
- Underground Stormwater Detention/Retention System
- ADA Accessible Site Design
- Site Landscaping and Privacy Fencing
This project consisted of developing a new public park in Lakeside, Montana. The existing project site contained a hotel, small business office, parking areas and a residence. The project consisted of demolishing the existing improvements and developing the site into a new community park, aptly called Volunteer Park.
RPA provided civil engineering services to design improvements to Adams Street, a 37-stall
asphalt parking lot, storm drainage, water and sewer improvements and ADA compliant
bicycle/pedestrian paths through the park. RPA prepared civil technical specifications and
construction drawings. During construction, RPA provided construction administration and
observation for the project.
Robert Peccia & Associates (RPA) also provided civil engineering for the expansion of Volunteer Park in Lakeside, Montana. RPA provided civil engineering for new sidewalk, curb and gutter, drainage and grading. RPA worked with the Montana Department of Transportation to work within their Right-of-Way. The project expanded the Volunteer Park and provided additional green space and pedestrian walkways throughout the park.
KEY PROJECT ELEMENTS:
- Community Park on Flathead Lake
- Boat Docks
- Swimming Area
- Lakeshore Improvements
- Asphalt Parking Lot
- Storm Drainage Improvements
- MDT Encroachment Permits
- Construction Administration & Observation
Ennis Big Sky Airport is open and fully operational following completion of their $15.3M major airport improvement project(s) to expand their runway to meet FAA required safety upgrades for their substantial use aircraft grouping. Improvements included land acquisition, full reconstruction of their existing runway, widening the runway to 100’ width, lengthening their runway to 7,600’ total length, constructing a 50’ wide full length parallel taxiway (shifted away from the runway), reconstruction of their south apron, construction of hangar access taxilanes, major electrical and navigational aid improvements, major drainage improvements, and wildlife fencing.
Robert Peccia and Associates was the engineer for all improvements, and SK Construction was the prime contractor for the construction project.
- Land acquisition – 11 different parcels were acquired from 11 different landowners. In addition 4 construction easements / permits were attained
- Earthwork – Nearly 1.2M cubic yards – enough to bury a football field 675’ deep
- Drainage / Culverts – over one mile of storm drainage culverts (5,528’) – largest culvert was 60” diameter so you could walk through it hunched over
- Gravel – Nearly 60,000 CY of subbase and base course gravels
- Asphalt – Over 38,000 tons of asphalt (1,300 truckloads)
- Paint – over 43,600 square feet of paint
- Lights – 284 runway and taxiway lights and an additional 22 lighted guidance signs
- Cable – over 61,000’ of electrical cable (11.6 miles)
- Fence – over 26,400’ of fencing (5 miles) and 29 gates
