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.

Caloosahatchee River West Basin Storage Reservoir (C-43 WBSR)

Developed by C-43 Water Management Builders for the South Florida Water Management District (SFWMD) and U.S. Army Corps of Engineers (USACE), the C-43 West Basin Storage Reservoir is a 170,000-acre-foot infrastructure project designed to store excess freshwater from the Caloosahatchee River, stabilize salinity levels, and prevent algal blooms. MC Squared provided critical laboratory management, construction materials testing, and quality control, ensuring compliance with USACE standards. Our contributions—including testing 22 million cubic yards of embankment, 110,000 tons of soil-cement armoring, and 19 miles of soil-bentonite cutoff wall—have helped ensure the reservoir’s durability, reliability, and long-term impact on Florida’s water resources and communities.
