[maxgallery id=”5034″] The 181 Fremont site is bustling with activity as construction crews steadily excavate and set up deep foundations for the future 802 foot tower. Using drilling equipment, workers are digging shafts and setting piles hundreds of feet into the ground to the bedrock below. One such shaft made news recently as it extended 263 feet into the earth with the last 30 feet penetrating into the rocky Franciscan Complex. The deep six foot wide shafts, strengthened with concrete and reinforced steel, are needed to support the weight of the relatively narrow structure against settlement, wind and seismic forces.
A recent onsite tour showed an active hydraulic auger boring out a shaft with a dump truck nearby collecting the freshly excavated earth. Nearby, huge coils of reinforced steel sit waiting to be plunged into future concrete filled shafts. Once the foundation piles are completed, an underground concrete base mat will be installed and support the future building’s steel exoskeleton. General contractor Level 10 expects shaft drilling, piling and excavation to take roughly a year to complete with the subsequent above ground work extending for another two years.
The 55 story building, owned by Jay Paul Company, will be notable for its height, compelling design, and integration with the upcoming Transbay Terminal. Building renderings show irregular positioned windows, sharp angles, and varying widths that combine elegantly together to form both a modern and bold design form. An open terrace splits the lower commercial floors with 67 ultra luxurious residences (Park 181) on the upper 19 floors. When complete, the building designed by Heller Manus Architects will harmoniously complement the upcoming Salesforce Tower and be a welcome addition to the changing San Francisco skyline.
