Abstract: This paper will present the Construction Mangement and Program Management planning and execution at the Saint Louis River/Interlake/Duluth Tar (SLRIDT) remediation project, Sediment Operable Unit. It will describe the use of fixed price/fixed scope contracts and design-build contracts for the various components of this $60 million multiyear contaminated sediments remediation project. In addition, techniques used to track progress and costs against a cost-loaded base schedule and Earned Value will be described.
The SLRIDT site is a former steel mill and coke-making operation (closed in 1962) on the St. Louis River, approximately four river miles upstream of Lake Superior. The site includes approximately 255 acres of land and river embayments, wetlands and shipping slips. The aquatic portion of the site is approximately 90 acres. Onsite sediments are contaminated primarily with Polycyclic Aromatic Hydrocarbons (PAHs). The project requires a combination of dredging and in situ capping along with the construction of an on-site contained aquatic disposal (CAD) facility for the dredged sediments. Approximately 800 people live within one mile of the site. The Minnesota Pollution Control Agency (MPCA) is the lead regulatory agency for the project.
Hard Hat Services (HHS) provides management services for the private corporate Responsible Parties including constructability reviews, pre-qualification and bid-phase services, and on-site construction administration and management.
The first year of the project has been completed, including: The construction of a 2,000 foot long sheet pile wall
The contracting approach and schedule for 2007, 2008 and 2009 will be described.
