PROJECT DESCRIPTION
85 BOSTON STREET, PHASE 1 EVERETT, MA
MORRIS-SHEA PROJECT COMPONENTS RIGID INCLUSIONS
651 DEWAAL PILES: 95’ – 133’
851 DEWAAL PILES: 65’ – 70’
PROJECT OVERVIEW
Birmingham, Alabama deep foundation contractor, Morris-Shea, installed nearly 1500 rigid inclusions at a new 650-unit multi-family development in Everett, Massachusetts. Foundations for this six-story building project required the construction of rigid inclusions for ground improvement at the site of an old Boston Street debris recycling plant. The Morris-Shea team utilized two Fundex 3500 drill rigs, including one with a unique clamping system at the top of the mast, for installation of continuous drilled DeWaal rigid inclusions ranging in depths up to 133 feet.
PROJECT DESIGN
Rigid inclusions were a value engineered alternate design for the multi-story project. DeWaal rigid inclusions were specified to accommodate the variable density of the top fill. The loose fill, including gravel, silt, clay and debris was underlain by very soft organic silt and considered likely to encourage settlement. Rigid inclusions minimize settlement in compressible soils such as those found below this site of an old Everett, MA recycling center. DeWaal rigid inclusions are topped with a load transfer platform to further disperse the structure’s load.
