Squantum Gardens
Project Details:
Owner: E.A. Fish Inc.
General Contractor: Suffolk Construction Company
Duration of Work: 10 weeks
Subsurface Conditions: Fill underlain by peat, marine clay, silt and sand. Fill layer consisted of sand with brick and concrete fragments.
Approximate Key Quantities: 1,200 Controlled Modulus Column (CMC)® rigid inclusions
Project Overview:
Ground Conditions:
The project site was previously developed with lightly loaded, two-story frame structures with conventional shallow spread footings. These structures and footings were demolished to prepare the site.
The subsurface conditions included 5 to 8 feet of fill to underlain by peat, marine clay, silt and sand, and bedrock. The fill layer consisted of sand with brick and concrete fragments. The top of the peat deposit was 7 to 10 feet below the ground surface The peat was very soft to medium stiff, and ranged in thickness from 3 to 9 feet. Bedrock was present at depth ranging 64 feet to 86 feet.
Solution:
Menard provided a design-build solution to stiffen the ground that included the installation of 1,211 Controlled Modulus Column (CMC)® rigid inclusions to depths up to 31 feet. Menard’s ground improvement design reduced settlements to within the limits specified for the project.
