During the time since our last post, multiple concrete pours were made as shown in the photos above. The process includes using a laser-guided automated screed and large ride-on power trowels. In the last photo, you can see the slab is covered with plastic to ensure that moisture is retained allowing the concrete to cure slowly, yielding the highest strength.
Site work continued with underground utilities, removal of overburden/trash and installation of the underground detention system.
The filter tanks shown above weigh nearly 90k lbs. each and have 52 filter cartridges each; these tanks will filter sediment and other environmental pollutants before storm water is discharged off-site.
A major feature of the site is the arches shown above. Crews attached the end caps to the arches and lay grouting to the keyway between the two, which bonds the structure and concrete foundation together.
The proposed location of Duhart’s Creek will run adjacent to the wall footing. The crews have finished the sheet piles that act as scour protection for the basket style wall footing.
