SGH designed the structure for the 239 ft dia., 32 ft tall concrete tanks in conformance with ACI 350 – Code Requirements for Environmental Engineering Concrete Structures. Highlights of our work include the following:
Finite element analysis to verify the design of the tank structure, which comprises a cast-in-place concrete, two-way, flat slab floor structure, cast-in-place concrete walls, and a precast concrete roof structure with cast-in-place concrete topping
Fluid-structure and soil-structure interaction analysis for specified seismic accelerations
Computer simulation of the early-age thermal and shrinkage behavior of the concrete and development of a construction sequence along with concrete curing and protection measures to minimize cracking
Design of the buried roof waterproofing system and drainage
Construction administration services including observation of the work for conformance with the design
The project also included a new above-ground building, dams, and associated structures on the Blue Hills Reservation. Landscape features, designed by others on our team, include upland meadows, upland forest and meadow edge (reforestation), a shoreline peninsula, walking trails, fencing and gates, site lighting, and landscape planting.
