Techniques for successfully implementing in‐situ remediation systems

Abstract

AbstractAs the remediation industry rapidly matures, a greater emphasis is placed on providing on‐site remedies involving in‐situ soil and groundwater technologies. Selecting and implementing cost‐effective technologies requires a defined working process focused on integrating the relationship between the design engineer/scientist and the remedial contractor. This article briefly explores various contractual vehicles and their effect on the designer/contractor relationship and identifies preconstruction documents needed to initiate a remedial construction program. A detailed discussion is presented that describes the transition from remedial design to remedial construction and offers practical application of preconstruction, construction, and postconstruction techniques. Preconstruction techniques involve communication processes and procedures designed to reduce installation uncertainty, address constructability issues, promote value engineering alternatives, and reaffirm the project objectives. Construction techniques focus on effective ways to communicate and document problems and solutions encountered during construction activities. Postconstruction techniques describe ways to provide useful information that may have a continued effect on system performance or used to document the achievement of project goals.
