Environmental Remediation Technology

This 8 step process provide a “roadmap” through the remediation process, along with the insights gleaned from the collective experience of the members of the CII Environmental Remediation Technology Research Team. Each step identifies key issues for management consideration. These steps are listed below and details are provided in the research. This environmental remediation process can be applied to any regulatory jurisdiction. (RS48-1, p. 2)

Step 1 - Problem Identification

Step 2 - Preliminary Remediation Planning

Step 3 - Site Characterization/Risk Assessment 

Step 4 - Feasibility Study and Remedy Selection 

Step 5 - Final Site Remediation Plan 

Step 6 - Remedial Design Process 

Step 7 - Remedial Construction Process 

Step 8 - Post Remedial Construction Activities 

Improper management of soil and water contamination issues can cause disproportionate project delays and cost growth. Project planning must consider the possibility of encountering contaminated soil or water. This research highlights ‘things to consider’ as part of the planning process that limits the impact of environmental site conditions on the project. The planning process will assist the management team in asking the right questions and knowing what to do with the answers. A few examples are listed below, while the research material includes the detailed research findings. (RS48-1, p. 6)

• Include contingency planning in the project schedule … plan for the unexpected
• Incorporate response and reporting procedures in the contractor’s scope of work
• Understand alternatives for handling and disposal of contaminated soil
• Be aware of cost and risk issues

The planning process includes specific planning suggestions for both:

• Soil contamination - consider the type of soil, where it can go, and cost to dispose (reference figure below)
• Groundwater contamination - can add significant expense to your project; avoid groundwater where possible

The unusual features of contaminated site remediation projects suggest that non-traditional or innovative management and contracting strategies may be beneficial. This research indicates that Turnkey and Design/Construct management structures are the most effective for remediation projects. (RS48-1, p. 9)

IR48-2, Environmental Remediation Management: An Eight-Step Process

Identifies the critical steps that should be followed in the remediation process, and the key management issues and actions that should be taken at each step to achieve the goals of the remediation project. Each of the 8 steps includes key management issues, activities, and concepts needed for that step.

SP48-3, Influence of Potential Soil Contamination on Construction Projects

Provides highlights of a planning process for soil and groundwater contamination that limits the impact of environmental site conditions on the project. This tool includes two key appendices:

• Appendix A – Procedures for the collection of site environmental information (SP48-3, p. 21)
• Appendix B – Good environmental practice criteria for construction projects (SP48-3, p. 27)
