Progress in all areas of Gastonia

 

Area shown is one of two islands in the parking lot

There are two long “islands” that were prepped for curb pouring. These islands will separate the two parking lots at Gastonia.

 

New utility poles shown before lines are relocated.

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.

 

Excavator placing fill material

 

Fill Material Shown here

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.

 

A top view of the raft footing at the south side of the arches

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.

 

Crews prep for a pour near the loading dock

First pour of concrete for Truck Turn Around Area.

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.

 

Walk-in Storage Cooler installed

Cooler/walk-in storage has been installed and the next step includes installing quarry tile and stainless base/trim.

 

Metal Stud Installation

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 Installed

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.

 

EIFS work shown on external of building

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.

The Three Rs in Gastonia: Raft footing, Rip Rap and Rubber Membranes

Hydromulch on corner section of site

The SW corner slope with ECO-Flex hydro mulch held up well to the past week of storms that dropped over 3” of rain in 7 days.  The mulch has seed, fertilizer, and tachafier (a type of polymer) that helps the organic mulch bond to the soil and helps reduce eroding of the slope.

Basket wall construction

The civil construction continues as the site contractor cuts out an area for the basket retaining wall. These walls once finished will measure over 40 feet; starting at the cut from the top of slope to the bottom where the wall footing will be.

Waterlines progress around site

The waterlines are being laid and crews are ready to tie it into the existing lines around the site. Before service can be sent to the building, the lines will have to be filled, flushed and treated with chlorine. In addition, the lines will be tested for bacteria as well.

Rip rap spread amongst the footing

We are using rip rap to condition and stabilize the ground under the raft style footing for the basket walls.  Rip rap is the rock or other material used to strengthen structures against water and natural erosion.  The basket walls will cross over each end of the double arches and hold the roadway to be constructed above.

Crews complete the raft footing after the rip rap install

The raft footing for the basket walls shown have 3 layers of geo grid and 2 ft of stone that is wrapped by another fabric like a “burrito”. This type of footing is used for the basket walls so that the wall is able to move and float on the marginal soils underneath without compromising the integrity of the wall itself.

Roofing crews installing membrane

The building work this week featured our crews began working on installing the membrane for the roof. In the photo above, the white area of the roof is the rubber membrane. This membrane is lightweight and allows for rain water to move more freely.

 

 

Site & Building Progress Continues

Repair work performed on access road due to heavy rains

Overview of site with arch feature shown

There is an inspection done weekly onsite for erosion control. Due to the heavy rain events we had there were a lot of the erosion control devices that needed to be replaced, repaired, or improved upon.  Thanks to the rainout days and 2 ½” of rain, this was the focus of our site work last week.

To date, we have undercut over 15,000 cubic yards of wetlands, hauled over 60,000 cubic yards of overfill and trash, laid 340 linear feet triple run of 72” corrugated metal pipe, installed over 2,000 linear feet of 60” underground detention system pipe and installed the twin arch spans measuring 75’ long by 49’ wide by 17’ high.

 

Foundation finished & Walls Started

Progression of work on the southern wall

During the last few weeks, we’ve seen the building work begin as the site work was winding down.  The foundation is poured and the forms for the walls started on the southern wall. Brick work was began as the wall concrete pours were completed

 

Northern Wall Shown Here

Unloading of the Roof Steel Started

Our crews began to unload the first loads of steel for the roof.

Other necessary structures for the roof steel will be started soon and topping out should be completed as well.

 

Scaffolding and bricks for the mason work for one of the walls

Scaffolding for the Loading Dock Area Walls

Sample of the Bricks used in the Walls

Masonry work was started throughout the building as the walls were finished out.

 

Foundation for wall before concrete pour

Steel Installed for the Retaining Wall

Concrete Pour Retaining Walls

Concrete pours are still a vital part of Gastonia. The retaining wall in the loading dock area was poured last week.  Subgrade work has started after the forms were stripped. The driveline concrete will be poured at the site by our crews soon. Progress continues with the walls up and the roof steel delivered.

 

 

Fine Grading Operations have begun, no thanks to the weather!

We have been working a seven day work week the last couple of weeks to get the fill material finished for the pad and staging area, followed by the fine grading operation.  The only exception when delayed by the ice and snow of last week.

We have now completed the sheet piling that surrounds the bridge footings and will start driving “H” piles the first of this week. De-water of the area is the main operation for now.

Our Utility crews have been doing double duty to get the water and storm in around the building.

Building Pad and Underground work nearing completion

We made good progress this week and at week’s end we had achieved about 95% of the building pad undercut. We also completed the geo-grid and select back fill material installation along two sides of the pad, a design element to protect the building pad’s integrity along the Duhart’s Creek of the building.

Once the fabric and select back fill material was completed our fill operation then concentrated to bring this last remaining area up to grade. (About 15’ vertical)

Overall, a good week, although inclement weather continues to become a larger a factor as it is typically  during this time of the year.

On Monday, The underground detention system was started.  This system will have over 1,240 LF of 60” CMP and will be located underneath the parking lot area.  One of the design functions of this system includes a unique filter system to trap sediment and petroleum before rain runoff leaves the system.

Work Continues For Gastonia

The site grading contractor has been taking advantage of the great weather in late October to get a jump on the undercut for the future building pad. Multiple layers of grid and stone are being used to insure a stable building foundation.

Granular Material and Fabric Covering

Through the month of October, the site contractor has progressed with the installation of the triple 72”CMP (Corrugated Metal Pipe). This is being installed to relocate an existing storm stream under the future parking lot area.

Forming of 72" Pipe Collar

The relocation of the existing outfall sewer was a 24/7 operation after finding the condition of the existing VCP pipe. Crews worked round the clock for 7 days to install, test and cut over more than 1200lf of new 18” sewer line.

Sewer Crew Setting Up For Relocation Process

Night Work for Sewer Relocation

The site contractor was able to get the transition collar from CMP to RCP in on the triple 72” pipes before the Thanksgiving Holiday.
