Buildings
University of Montana Research Labs Building
University of Montana
Missoula, Montana
This project included construction of a
new labs building within the campus of the University of Montana. The proposed structure was slab-on-grade construction with interior
column footings and a basement area. Our investigation was performed
using the Orion drill rig. Our evaluation considered groundwater
levels, bearing capacity, and settlement criteria. Recommendations
included foundation type, allowable bearing values, and water drainage
system provisions.
Berman Project
Bozeman, Montana
The proposed
project was a multi-level, primarily glass office structure surrounded
by a constructed pond. Subsurface materials consisted on soft plastic
silts. Design challenges included low tolerable settlement due to the
amount of glass, frost-susceptible soils, soft subgrade conditions,
and water infiltration consideration from the adjacent pond. Orion
recommended and designed cast-in-place concrete piers for foundation
elements. The final report presented pier size and depth requirements
based on bearing capacity (skin friction and end bearing), lateral
capacity, and uplift restraint requirements. Submittals included
geomembrane details to control water infiltration from the pond, and
installation recommendations and specifications for the concrete
piers.
