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.

 

 

Footing Crews Laying Foundations…vertical construction starts soon.

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.

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.
