GHD’s Proactive Construction Management Delivers Successful Closure of Polluted Dump - 1

Project Summary Organization: Guam District Court Receiver, Gershman, Brickner & Bratton, Inc. on behalf of the Guam Solid Waste Authority Construction Manager: GHD, Inc. Location: U.S. Territory of Guam, Chalan Pago-Ordot municipality Project Objective: Closure of a toxic dump, mitigation of hazardous conditions, and construction of a network of new environmental safeguards Products Used: ProjectWise Construction Management GHD's Proactive Construction Management Delivers Successful Closure of Polluted Dump ProjectWise® Construction Management enabled GHD to utilize an enormous amount of data to save time, mitigate claims, and keep a dispersed project team on track Fast Facts • Guam needed to close a former military dump that was introducing polluted leachate into the Lonfit River. • The complex project required a construction management system that could connect geographically dispersed team members and organize a huge volume of project data. • ProjectWise Construction Management allowed the team to mine and utilize project data to successfully mitigate weather-related claims and other challenges. • GHD was able to collaborate more effectively with contractors and stakeholders spread across 10 time zones around the globe to make the project a success. ROI The automated workflow saved approximately 800 work hours in submittals and RFI management. The GHD team saved over USD 340,000 in change order costs through negotiations backed by ProjectWise Construction Management data. By leveraging project data, GHD was able to negotiate a time extension of 107 work days, instead of the 202 days requested by the contractor. GHD reduced the use of paper documents by 99 percent. Project completed 55 days before deadline. A Significant Threat to Guam's Environment The government of Guam needed to close a 50-acre dump that was introducing millions of gallons of polluted leachate into the Lonfit River, which feeds into the island's Pago Bay. Originally built in the 1940s by the US Military, the Ordot Dump was also the source of significant air pollution from methane gas emissions. The site was known as a dangerous eyesore with occasional fires, and was overrun with flies, "ProjectWise Construction Management helped us collaborate more effectively with contractors, and the overall organizational and archival capability has been very important in making this project a success." — Paul Baron, P.E, Principal/Pacific Business Group Manager, GHD feral pigs, and dogs. In 2004, the Government of Guam, the US Department of Justice, and the Environmental Protection Agency agreed to a consent decree for the closing of the site, and in 2008, Gershman, Brickner & Bratton took over the site as the US District court-appointed receiver. The Ordot Dump Closure was a complex infrastructure challenge that required the removal of hazardous materials and the construction of a network of new environmental safeguards including a complete cover system, a leachate collection system, a gas flare, sewer system improvements emergency backup generators, security fencing, stream relocations, wetland mitigation, and roadway improvements. The project had two phases and overall project deadlines, and the delivery method was design-bid-build for construction with Owner Agent CM. Collaboration and Accountability The Ordot Dump Closure project was located in a remote, harsh tropical environment, surrounded by pristine rivers and jungle, and required the collaboration of numerous contractors and specialty subcontractors. As the construction manager, GHD recognized that they would need a construction management system that could facilitate collaboration and accountability for the entire project team and stakeholders—including the owner, Gershman, Brickner & Bratton, located 10 time zones away. The system would also need to accommodate a large volume of construction documents and communications. For this USD 42 million project, GHD chose ProjectWise Construction Management (formerly ProjectWise® EADOC®). The system enabled the team to manage, mine, and utilize an enormous amount of data to mitigate challenges and make the closure project a success. ProjectWise Construction Management's detailed electronic history was used extensively by GHD to keep the project team members on track. "ProjectWise Construction Management helped us collaborate more effectively with contractors, and the overall organizational and archival capability has been very important in making this project a success," explained Paul Baron, principal construction manager for GHD. "The history tracking really helped in situations when the contracted parties became unresponsive. I could easily see a history of who did what when, and show the parties involved where things went off track."
