Due to the high number and close proximity of the piles, access was extremely difficult. Most materials were craned into and out of the footprint. Scheduling and sequencing of the concrete pour was difficult and required constant communication with the various crews to coordinate without interfering with cranes, concrete pumps, and other equipment and activities on the project site.
