Final Touches to Earthwork

We are pleased to present completed earthwork. This shot is taken from the new roadway looking down on the retail anchor building. In view is a portion of the stream work and the recently grassed slope towards the back of the building.

This view shows  a different angle of stream work and planting with the new roadway, bridge and retaining walls in the foreground.

Notice the wet road in this image? It’s from the sprinkler system that’s now operational. This will help the newly planted sod take root.

 

Gastonia Channels Forward

New channel staked

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 installation

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.

 

Curb crews pouring concrete

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.

 

Main Drive of Parking Lot

Walls shown after mudding and tape process

The interior walls were taped and mudded after metal studs were completed last week. Here the walls are shown after this process; ready for final sanding and primer.

 

Grading Stones and sidewalks started at Gastonia

 

Crews prepping subgrade

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.

 

Motorgrader spreading stone

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.

 

Roller used to compact the stone

A roller was used in the final step to compact the stone. The density requirement for the stone is 100% per AASHTO T99 standards.

 

Crews working on last bits of parking lot area

Crews working on last bits of parking lot area

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.

 

Crews relaying material to center of arches

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.

 

Top Soil installation in planters

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.

Crews relaying material to center of arches

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.

 

Crews working on sidewalk forms

Sidewalk forms for rear of building

Sidewalks are beginning to take shape and the crews are slated to start the pours this week. Preparation was completed last Friday.

 

Crews finishing walls for painters

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 Crew Priming Wall

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.

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.

Civil & Building Improvements Continue

Fabric installed by civil crew

Raft Footing being installed which consist of a rip rap layer, fabric and stone to support the gabion walls.

 

Spreading rock in footing area

Installation of stone layer within the raft footing. The 4’ thick raft footing will support a 22’ high gabion wall when completed.

 

Crew members laying geogrid material

Footing area after geogrid installation

Geogrid, a high-tensile plastic mesh, is a major component of this work. These 2 layers of basket wall will be covered once the slope grades are finished.

 

Masonry work going up

Prep and Paint of front entrance

On the building side of things, masonry work is ongoing. As the masonry work is being completed, the entrance and feature wall of the building is prepped for paint.

 

Planter 1 poured and irrigation installation shown

Planter 2 prep work before pour

The site will feature planters near the entrance area of the building. Planter 1 was poured and stone caps installed with irrigation installation started. Meanwhile, Planter 2 was prepped for the concrete pour and irrigation will follow.

 

Stone laid of Subgrade for drive to loading dock

Loading dock area after pressure washing & paint prep

The loading dock is getting closer to finishing as our crews spent the week grading the drive. Stone was placed at the Subgrade level and the civil completed for access. The actual loading dock area was pressure washed and prepped for paint.

 

Conduit Installation on site

In other areas of the site, the electrical crews neared completion of the conduit runs and tying into the main power

 

 

 

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.

 

 

Loads of Civil Work This Week

Initial work on the basket wall

Civil work this week involved excavating a slope for a 20 foot high gabion-style basket wall. This area will eventually feature a retaining wall for the upper site where the parking lot will be located and the lower area for the recently relocated Duhart’s Creek.

Front side of building & Parking Lot civil work

Landmarks nearing completion this week include the parking lot sub-grade and the block work on the front of the building.

Completed cut slope

On the southwest area of the site, overburden trash is almost completely gone. Nearby, a large cut slope has been seeded and mulched so that landscape efforts can get a head-start.

Grading work in mid-process

Grading work for an area on the site that will be a mitigated wetlands area began on a soil nail wall that eventually will extend vertically down over 20 feet.

Electrical crews installing conduit runs

In addition to the civil work this week, the electrical crews began installation of the conduit runs for the power feeds for the building. These runs will feature over 2,000 linear feet of conduit runs around the building site after completion.

Site & Building Progress Continues

 

View of Duhart Creek as Erosion Control Work Is Performed

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
