The 700 On Washington

The project consisted of the demolition of a two-story building and parking lot for the construction a new six-story student housing building with first floor retail space.

Location: Minneapolis, MN
Client: Cuningham Group
Services: Structural, Civil
Square Feet: 127,000
Construction Costs: $12,500,000
Construction Materials: Masonry, Precast Concrete, Wood
Provided civil and structural engineering services for the design of a 127,000 square foot, H-shaped six-story apartment building with 98 student apartments providing 157 bedrooms.
The building features one level of below grade parking that contains 49 parking stalls, a large bicycle parking room, fitness and tanning rooms.  The street level was designed with a high 17’-4” floor to floor height for retail spaces that included an outdoor patio space for a restaurant. 
The building also included a large amenity room in the corner of the 6th floor that overlooks campus.  The structural system consists of a slab on grade at the lowest level, two levels of precast concrete framing, and five levels of wood framing for the upper floors. The foundation design required temporary soil retention along the north and south building walls due to the proximity to the property line, of which a portion of the south wall was coordinated with the sheet pile engineer to be designed as permanent retention along the drive ramp to the underground parking. 
Careful coordination was also required along the east building wall due to the proximity to the existing building.  The high first floor height also required masonry shear walls be used for the lateral system of that level as the height was too great to cantilever the precast columns above the grade level.
Stormwater management was not needed for the project due to the overall size of the project and the project parcel being less than one acre in size.  Construction for the site was limited to only have disturbance within the curb lines and no disturbance within Washington Avenue, due to the recently completed light railway.
