CR 817, Lee Road, and South Sweetwater Road Widening

Douglas County, GA ESA Phase I and Phase II

MC Squared (MC²) is supporting Lowe Engineers on a roadway widening improvement project along CR 817, Lee Road, and South Sweetwater Road in Douglas County, Georgia. The project aims to improve traffic flow and safety through expanded roadway capacity and infrastructure upgrades. Before design and construction can proceed, a thorough environmental assessment is required to identify and mitigate potential risks.

Our team was engaged to perform a Phase I Environmental Site Assessment (ESA), which involved reviewing historical land use records, regulatory databases, and conducting a site reconnaissance. 

During this assessment, we identified multiple underground storage tank (UST) sites in close proximity to the project limits, including two active tanks located directly adjacent to the planned alignment.

Due to these findings, the project advanced into Phase II ESA fieldwork. Our environmental professionals are conducting subsurface investigations, including soil and groundwater sampling, to evaluate potential contamination and determine whether further remediation or monitoring may be required. The data collected will support environmental compliance and inform planning decisions ahead of project development.

MC² is proud to deliver detailed, data-driven evaluations that support responsible infrastructure improvements. Our work on this project helps ensure safety, sustainability, and regulatory alignment for long-term development in Douglas County.

I-4 at SR 33 Interchange in Polk County, Florida

MC Squared Construction Services in Polk County

MC Squared is serving Lane Construction and the Florida Department of Transportation (FDOT) as the Construction Support subcontractor for the I-4 and SR 33 Interchange Reconstruction project near Lakeland, Florida. The project will convert the existing traditional diamond interchange into a Diverging Diamond Interchange (DDI), a design that reduces traffic conflict points and is expected to improve safety and operational efficiency for thousands of daily commuters.

Our team is providing field quality control, foundation inspection, laboratory testing, and engineering support throughout the construction phase. Field technicians and inspectors—certified through the American Concrete Institute (ACI) and FDOT’s Construction Training Qualification Program (CTQP)—are performing continuous on-site testing and verification of materials and structural elements. In these early phases, our scope includes oversight of auger cast pile installation for sound and noise walls, drilled shaft inspection, and laboratory testing of embankment, backfill, and concrete specimens in accordance with FDOT specifications.

We are also providing engineering services through a dedicated Quality Control Manager who is responsible for tracking laboratory data, coordinating with project stakeholders, and ensuring test results are entered into the FDOT Materials Acceptance and Certification (MAC) system. These services are critical to ensuring the integrity of the constructed elements and compliance with applicable standards as the project progresses.

Construction is anticipated to continue through 2025. As the interchange takes shape, MC Squared remains committed to delivering reliable, detail-oriented oversight in support of Lane Construction and FDOT’s shared goal: a safer, more efficient corridor for the surrounding community and the broader Central Florida region.
