The bollards for the handicap signs have been installed in preparation for the remainder of the concrete sidewalk to be formed and poured.The stream work is ongoing. In this section, the new channels have been graded and temporarily stabilized prior to the stream being diverted to the final location.
We are completing the aggregate base stone in the parking lot and prepping for the remaining curb and gutter. Plans are to have the remaining parking area covered with asphalt binder by the end of this week.
We have finished up to the ½ way mark of the soil nail wall. Here our team is getting ready to start blowing shotcrete on the wire mesh.
We have topped out the block in this area and will install the cap block to finish out. They have roughly 150sf of wall left to complete.
The staging area has been graded and the stone placed. This area will be covered with stone and asphalt binder.
Crews started the soil nail wall this week. This is the first part of the wall, and provides structure for the concrete that will be poured later.
Crews continue to cover subgrade with stone.
The off-site mitigation work is looking good. All the grading is complete with 75% of the small plantings in place. The larger plantings will be done next week.
Crews started the demolition of the concrete median for the offsite roadway improvements. The crew will have to work closely with the NCDOT and the resurface contract, to be completed at the same time.
Stone crews yield way to paving crews as the first lift of asphalt is put down in the parking lot.
The channel defining process began with the crews staking out the new channel and started to install the rock vain on the downstream side of the arches.
Rock vein is installed and the crew is working on the riffle section going under the arch. There will be 13 of these structures to be installed in the new channel.
Over 2,000 linear feet of concrete curbs was poured by the Curb crews. There is around 800 linear feet left to pour in the parking lot and will be finished next week.
Fine grade crews are working to get parking lot grades cut and stone placed. This is the main drive on the east side of the parking lot.
The Storefront is coming along nicely. Glass is being installed, as well as some of the sidewalk signs.
We are finishing up our sidewalk prep work with lights, tree grates and bollard sleeves.
We have also started our tile installation. Once all the pieces have been cut out for columns and sprinklers the tile will go up fast.
In the Food Ave area sheet rock is up, mud is being applied and paint will soon follow.
Crews worked all week prepping subgrade and getting the north main drive ready for stone. Some areas required an undercut after not passing proof roll initially.
Stone was used to spread the roads around the site to bring to grade. A motorgrader was used to spread the stone. The crews used water to assist in making sure that the optimum density is achieved.
A roller was used in the final step to compact the stone. The density requirement for the stone is 100% per AASHTO T99 standards.
Site crews have worked to get the last lifts of fill in the parking lot area so that concrete curb and gutter can be poured. The crews will fine-grade the parking lot for stone after the curb and gutter is done.
The crews installed a 55 foot wide raft that the basket walls sit on. The white fabric is a high strength geotextile material that wraps the raft.
Landscape crew installed the topsoil mix for the planter boxes in the front of the building. There is 3’ of topsoil over a 12” layer of stone. The fabric that covers the stone is for filtration purposes only. It acts as a barrier between the stone and topsoil.
Bailing material was placed in the center of the arches by a larger excavator as a mini-excavator placed it for compaction. This is a very slow process, but with the two crews working together it is progressing nicely.
Sidewalks are beginning to take shape and the crews are slated to start the pours this week. Preparation was completed last Friday.
Backer rods and colored caulk was completed on the outside of the building and as they finish, the painters are right behind them priming the walls.
Paint crews began priming the outside walls of the building and as of last Friday had completed 3 sides. The painting will begin this week as they finalize the last wall.
Blocking and framework has been completed in entrance and guest services area. Drywall was started and is on track to finish on schedule.
There are two long “islands” that were prepped for curb pouring. These islands will separate the two parking lots at Gastonia.
The relocation by AT&T of the utility service will have to be completed before the widening of Cox Road and new sidewalk construction can be completed.
Crews used an excavator with a 60’ long reach to place the fill material between the 78’ wide arches. The photo above shows the various materials and the need for some of the work to be done by hand.
The raft footing that started last week has 4’ of washed stone and 4 layers of grid inside. The 23’ high wall will be constructed on top of this footing.
Sitting on 6” of stone, the concrete slab for the truck turn around area got its first pour. This is the first of the +/-400cy of 4500psi concrete that is required for truck turn around area.
Cooler/walk-in storage has been installed and the next step includes installing quarry tile and stainless base/trim.
Metal studs were installed at the front Guest Services area. Once completed, the electrical work will begin and then the area will be finished by the sheet rock and paint crews.
Duct work in the front vestibule area was completed and wrapped. The metal stud installation shown on the right in the photo above was completed as well and sheetrock crews will be the next in this area.
The blade tower section of the building received EIFS this past week and is ongoing. This area, on the left side of the building, is where the signage will eventually be installed.
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.
We worked around the weather fronts this week and were able to complete the center foundation component for the bridge as well as the headwall for the Triple 72” on the downstream side.
We also made progress with the vertical construction and completed approximately 50% of footings. The masonry crews were quick to chase the foundation crews as soon as we poured footings .
In an ideal project, each trade will tend to nudge or “pace” the next trade which is our goal here.
