Butner, NC. June 20, 2025 - During the June 17th, monthly progress meeting, CDM Smith representative Bill Mason led project update conversations with project contractors and SGWASA team members. View meeting discussion topics, minutes, and media files below.

Site work has been completed at the Joe Peed Lift Station, including clearing, grubbing, erosion control, and initial excavation. The excavation process for the lift station structure is expected to continue. Dewatering systems are in place. Teams they will be finishing concreting (shotcrete) process soon.

At the East Middleton Pump Station, teams continue with drilling and blasting process, but have reported that the undercutting of unsuitable materials has been completed. Drilling and blasting is ongoing. Soil conditions are affecting the drilling progress.

Dewatering efforts are actively underway, with three sumps currently in place and two pumps operating nearly continuously. The number of pumps in use is currently limited by available power. Once temporary power is established, the plan is to operate four sumps outside the excavation pit and one within it to enhance water management.

Construction Progress and Site Activity

Recent activities include:

Joe Peed LS

Haren will continue to dig and shore up the excavation. The contractor plans to be close to completing the excavation process by the end of July 2025.

East Middleton LS

Drilling and prepping for blasting continues.
Plan to install pit boxes to cover the top 9 vertical feet of the excavation and will then begin to excavate down. GSI will plan to move back and forth from the Joe Peed LS to the East Middleton LS with the ongoing drilling.
Haren noted that the return of the rebar, formwork, and concrete design mix submittals would be beneficial to expedite construction. Teams plan to only review the rebar for the lift stations that would be acceptable to help expedite work.
Materials will be ordered in the next month, after the release of the shop drawings.
