Hillsborough County Northwest Solid Waste Transfer Station Improvements

Ardurra delivered engineering solutions for the Northwest Solid Waste Transfer Station replacement, overcoming complex challenges of constructing a new facility on a closed landfill while maintaining continuous operations within an $11 million budget. The original 1980 facility required complete replacement due to age and site limitations, demanding creative approaches to achieve county objectives without service interruption.

The solution involved driving piles into the landfill around the existing building perimeter, constructing a new metal building over the existing structure, and then demolishing the original building from the inside out while maintaining operations. The strategic retention of existing concrete floors, walls, and lower levels achieved significant cost savings while meeting performance requirements.

Key Project Highlights:

• Replaced aging 1980 transfer station on closed landfill site while maintaining continuous waste operations within a $11 million budget

• Implemented an innovative construction approach, building a new facility over the existing structure, then demolishing from the inside out

• Drove piles into landfill substrate around the existing building perimeter, providing a foundation for new metal building construction

• Retained existing concrete infrastructure, including floors, walls, and lower levels, achieving substantial cost savings

• Developed a detailed Construction Phasing Plan with innovative life safety measures enabling construction without operational impacts

• Coordinated complex permitting requirements for construction on a closed landfill with active waste transfer operations

• Delivered comprehensive services from initial planning through construction completion, ensuring seamless facility transition

The project earned multiple prestigious awards, including the 2016 SWANA Silver Excellence Award, the FICE Engineering Excellence Award, and the ACEC National Recognition Award, for its innovative engineering solutions. The successful replacement demonstrates exceptional problem-solving in constrained environments while establishing new benchmarks for solid waste facility construction on challenging sites.
