River Park Plaza

Stearns was approached by Howard S. Wright to furnish and install the structural steel package for this 88,000 sq.ft. office building. The super-structure consists of 2 levels of parking and 3 levels of office space. Stearns prepared cost-effective framing plans based on the structure’s geometry and loading criteria. Stearns determined correct member sizing, spacing and depths, and minimized vibration. In collaboration with the engineer-of-record, Stearns assisted with design development and construction documents. A challenge during construction was positioning the crane within the footprint of the building in order to erect the steel. Howard S. Wright accomplished this through strategically placing shoring under the elevated parking slab to support the crane, allowing erection to be accomplished in one continuous operation.
