Arthaus at Broad & Spruce
Project Overview
Test borings including rock coring were carried out to characterize the subsurface conditions for foundation and construction. A mat foundation was selected as the optimal system. Further PMT testing was undertaken by GeoStructures to effectively determine settlement of the mat under the tower. The use of the mat foundation over the caissons saved approximately $1.5 million. Caissons were utilized to support the podium in non-basement areas along the south end to prevent stressing the historic church basement walls.
Foundation settlement analysis was performed using a 2-D FEM program (SIGMA/W) to evaluate the soil-structure interaction among the tower mat, the podium footings, and the adjacent Center City One high-rise. A combination of spread footings and caissons (south end) were used for support of the podium.
Since the groundbreaking in June 2019, GeoStructures has been performing all of the special inspection services for this concrete structure including a nearly 4000 CY mat, grade beams, footings, cast-in-place concrete, rebar, floor flatness and levelness, floor edge profile, structural steel, sprayed fireproofing and intumescent paint, and laboratory testing of high strength concrete up to 14,000 psi.
