August ‘23 Update
Last month, the project groundbreaking ceremony took place. Use the link here to access APAH’s video re-cap of the groundbreaking and to hear key project partners speak about the importance of our project!
In the month of August, we finished vibrating the steel soldier piles in the ground and installing the initial 4’ of wooden lagging board. That kicked off our vibrated aggregate pier installation. The piers are needed to support the building loads imposed upon the columns and footings and to minimize building settlement. The project team has professional vibration monitoring set up around the perimeter of the site to notify us of any potential impacts to neighboring structures caused by seismic activity from our site. The vibration levels noted in the seismic reports confirmed that no vibrations approached or exceeded the thresholds above which the consultant would become concerned about adjacent damages or structural impacts. After the vibrated piles and piers were completed, we began excavating the central portion of the site to subgrade in preparation for heel block and raker installation.
Upcoming work includes completing heel block and raker excavation, heel block and raker installation (angled steel beams that provide lateral support to the SOE system), completing excavation to subgrade, and starting concrete foundations and MEP groundwork. As we complete our excavation, the aggregate piers will be tested to confirm that the in-situ soils meet the pier design parameters. This will confirm that the pier system will be sufficient to support the structure and minimize building settlement. We anticipate this groundwork commencing within the next 3-6 weeks. Once concrete commences, the focus of the project will be on building our structure vertically.
Excavators, skid steers, and forklifts will be expected on site for the forseeable future. Once concrete commences, a mobile crane will be staged parallel to Riggs Road NE on the west side of the project site.
