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.

Taking Advantage of Sunny Days

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.

Fill Operations Continue

We were impacted somewhat by the weather events last week but overall had a decent week.  Our fill operation for the pad continued in coordination with overburden removal, which revealed additional good fill material.

The bulk amount of the fill needed for the building pad should be in place mid next week and we will then continue to the parking fields.

We also finished all the 60” CMP portion of the underground detention system. The filtration system is in fabrication and will be on site in January.

The double steel arch bridge, a part of the future Gaston Mall Drive, started this week with the mobilization of the foundation crew.  We have started driving sheet piles around the footing locations of the bridge before the “H” pile installation which will support the concrete footings of the bridge.

Taking Advantage of the Weather

On the job last week we faced low temperatures mixed with some freezing rain, sleet and snow but were able to take advantage of a few good days of weather in between the rain and sleet.

We have now completed the building pad undercut and are continuing the grading operations in this area  by using  earth material from two areas of the job site and then blended it to speed up the fill process.

Anticipating a problem with the weather conditions at the first of the week, we doubled the size of the storm sewer crew and were able to get about 1,000 lf of the 60” CMP completed by Saturday.

Weather Slows Progress

The weather did not help the progress of the project any this week due to rainfall totals of almost three inches. The site contractor spent most of the week working on erosion control.

They were able to get things going later in the week continuing with the triple 72” CMP and the overburden removal.

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.
