Providing a full range of construction engineering services for clients’ infrastructure projects has been a vital part of GPI since its inception in 1966. We have been fortunate enough to have worked on some of the most recognized bridges in the world including the Brooklyn Bridge and the Manhattan Bridge in New York. We have taken our expertise and transcended our construction services to highway reconstruction and major alternative delivery projects such as the “new” Tappan Zee Bridge in New York and the Cleveland Innerbelt Parkway in Ohio.
