Georgia’s first public-private partnership to be financed with a tax-exempt bank loan, the I-285/SR 400 interchange reconstruction, has received a notice to proceed. North Perimeter Contractors (NPC) won the contract in early April to reconstruct the I-285/SR 400 interchange north of Atlanta for the Georgia Dept. of Transportation (GDOT) as a design-build-finance (D-B-F) project. NPC’s team includes Ferrovial Agroman US Corp. as lead contractor and the Louis Berger Group and Neel-Schaffer Inc. as designer-engineers.
GDOT’s original estimate of the cost of the project was $1.1 billion. GDOT was able to reduce the total project cost to $803 million, including right-of-way acquisition, preliminary engineering, conceptual designs, environmental studies, and other costs, partly because of NPC’s bid of $458 million for construction.
