Feasibility Study and Remedial Cost Analysis Services
Exponent applies its experience with feasibility studies and remedial cost
analysis to develop cost-effective solutions for our clients, including property
owners, present and past site operators, other potentially responsible parties,
prospective property purchasers and developers, and insurance companies. We understand the key elements needed to create truly realistic remedial alternatives and develop
the most appropriate and cost-effective remedy.
Key Elements for Cost-Effective Remedies
Effective use of remedial technology screening. Through careful use of technology screening, Exponent focuses the feasibility study by eliminating infeasible technologies
early in the process, thereby reducing the overall effort required. Because we do not
typically do design or construction, Exponent has no vested interest in the selected
remedy and thus our scientists and engineers are technically unbiased. We know which
remedial technologies work in which situations, and what the critical considerations are
with each technology.
Development of realistic remedial alternatives and conceptual design scenarios. Exponent’s multidisciplinary team works with our clients, onsite personnel, and regulators
to identify site-specific constraints and potential impacts to onsite operations and nearby
human and ecological communities. Our approach leads to the development of more
realistic remedial alternatives and conceptual design scenarios, which saves time and
money by minimizing the need for future changes to the selected remedy.
Risk-based cleanup level development, risk-based alternatives comparison. Exponent
toxicologists and ecologists perform site-specific analyses to support the establishment
of realistic cleanup goals, and to provide more appropriate comparisons of short-term
and long-term human health and ecological risks for different remedial scenarios. By
integrating the expertise of engineers, bioavailability chemists, toxicologists, and
ecologists, Exponent is able to provide sound, scientifically based assessments for
selection of cost effective remedial actions that are protective of human health and the
environment.
Objective evaluation of all remedial alternatives. Decision makers are often focused
on a particular presumed remedy. Exponent has found that its thorough and objective
evaluation of potential fatal flaws provides a sound technical basis for proceeding with
the presumed remedy and sometimes results in identifying a more cost-effective variation
of the remedy.
 Exponent recognizes the limitations of feasibility
study cost estimates for use in long-term planning,
liability estimation, and cost allocation for
environmentally impaired sites. Feasibility study
cost estimates usually target an accuracy of –30
to +50 percent, and typically do not include major
cost components, such as regulatory oversight,
litigation/negotiation, and internal administration,
and thus may not be sufficiently accurate for
these purposes. In remedial cost analysis, we strive to understand our clients’ goals
and constraints and develop realistic cost estimates to help them make well-informed
business decisions.
Methods that Exponent employs in feasibility studies and remedial cost analysis include
cost-benefit evaluation, Monte Carlo uncertainty analysis, sensitivity analysis, uncertainty
reduction (e.g., through targeted supplemental data collection), and decision analysis.
The following example projects highlight Exponent’s experience in performing feasibility
studies and remedial cost analysis.
