Daigle Engineers, Inc. was the Structural Engineer of Record for this renovation and new addition project for Rosie's Place in the South End of Boston. This project included renovations to an existing four story 5,000 square foot housing unit and a new 2,000 square foot rear addition which houses a new stair and elevator tower. The rear addition also has a new enclosed access corridor/ ramp on the first floor to link the newly renovated classroom space to the existing Rosie's Place headquarters.

Renovations to the existing space included rebuilding the existing front stairs and main center bearing wall, reinforcing the timber floors, re-supporting the first floor steel girders and masonry repairs. The rear four story addition included composite concrete floor and roof slabs on steel framing. The addition is structurally separated from the existing buildings and braced by steel braced frames on three sides of the elevator shaft. Foundations include concrete basement walls, grade beams and a foundation mat. Existing soil conditions dictated that the rear addition be supported by deep foundations. Helical piers were selected which consist of 10" to 14" diameter helix leads that embed approximately 15' to 25' in the soil sub grade. Site concrete retaining walls were also required for the project.

The $2.3 million project was completed in approximately 10 months.
