Current work: Workers inside and around the large white tent the east side of Ascon near Magnolia Street are conducting Pit F excavation work. The air treatment system is currently operating 24/7 during excavation. As of the week ending August 13, 2021, the excavation phase is over 50 percent complete.
You may see: Workers arriving before 7 a.m. for safety briefings. Workers, materials, and large equipment, like manlifts, small cranes, excavators, water trucks, forklifts, street sweepers, material hauling trucks, and waste hauling trucks, may be arriving and leaving the Site, Monday through Friday, and Saturdays if necessary.
You may hear: A low-level hum for the air treatment system, which has been mitigated with 20-foot and 8-foot sound panels and sound blanketing in addition to the 16-foot sound wall along Magnolia Street. Acoustical engineers have conducted sound metering in multiple neighborhood locations to confirm compliance with local ordinances for residential areas. This system is required to operate 24/7 during the duration of Pit F work to maintain a vacuum environment and treat air inside the tent for workers and our neighbors.
Construction sounds during work hours, like vehicle backup signaling required for worker safety and noises from equipment, such as the grout plant, supporting excavation within the tent. Workers will minimize backing up vehicles when possible and when it is safe for workers and equipment.
