Major segmental walls and tiered gabion basket walls are complete on the site. There are two small segmental walls remaining on the Jett Lanier Drive that ties to the Spine Road which should be getting started in the next couple of weeks.
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.
It’s been a while since the weather has cooperated. Last week, things changed and we found ourselves able to take full advantage of some good weather and continued the work in both building and civil areas.
The arch bridge crew has used the good weather to their advantage as well as the bridge arch construction was started and we expect to complete the arches next week.
Cut and Fill operations continue in the parking field. Storm drain installation in the parking area of the site is now 90% complete.
This week our footing crews started the foundations for the vertical construction once the pad was completed and accepted.
Our civil work continue to progress in and around the weather cycles. While our foundation crews poured out the east footing early this week for the bridge, the remainder of the crew was finishing up H-piles on the center footing. Our plans are to pour the center footing the first of the week. The arch structure is scheduled for delivery next week with erection to follow.
The concrete crews also poured the headwall for the outlet end of the triple 72” pipes.
With the turnover of the building pad this week, our crews have narrowed down the requirements for turn-over. Stone access road was installed around the building pad and in staging area. Our building superintendent is now on the job to start vertical construction.
We have now shifted the focus from the pad completion to the remainder of the site. Sixteen trucks cycled at a rate of 1.5 rounds an hour as we concentrate efforts to removing about 30,000 CY of overburden that overlays the fill needed to complete the balance of the grading operation.
Our work continues on the spine road through the site and this week we started driving steel H piles and as soon as they are complete we will form and pour reinforced concrete caps to support the double arch culvert bridge crossing Duharts Creek.
The New Year brought more un-needed weather to the site. The week started off with wet conditions. Taking advantage of sunny day windows the crews are using blending and dying techniques to keep the schedule moving forward.
Durharts Creek bypass was put into place to allow for the bridge foundation crews and pipe crews to work without water running through their work areas. The creek bypass will stay in place until the arch span bridge is erected.
Storm crew finished out the triple run of 72” pipe. Headwalls will be poured next week. The bridge foundation crew is hoping to have all the sheet pile piles in by the beginning of next week and start driving “H” piles that the foots will set on.
The waterline crews have started on the loop feed around the building that will provide both domestic and fire line.
Overburden removal and revealing good fill material underneath is still a huge factor in progress. Crews have hauled nearly 40,000cy offsite at this point. The site contractor has been running to operations to remove as much overburden as possible at the same time excavating good fill material to bring the pad and parking lot up to grade.
