HGL’s Prominent Leadership on DoD PBR Projects

Over the past 15 years, HGL has become a Performance-Based Remediation (PBR) industry leader, successfully managing  and executing single- and multiple-installation PBR projects ranging in size from $5 million to $45 million under both RCRA and CERCLA. HGL has completed these projects for Department of Defense clients, including the U.S. Army Corps of Engineers, Army Environmental Command, and Air Force, and it has successfully managed performance risk and liability for them using various remedial technologies. Additionally, HGL has 27 years of experience executing firm fixed price projects with challenging milestone performance schedules. With their extensive experience executing PBR projects, HGL’s staff has developed expertise in negotiating and securing consensus on all aspects of environmental remediation projects from the investigation through closure (end state) phases. HGL’s strong performance on these PBR projects is evidenced by the “Very Good” and “Exceptional” ratings below.
