(AECOM) is pleased to submit this proposal to the City of Richmond (the City) to provide bid specification development and bidding services for the groundwater remediation and site cap installation at the Former Manufactured Gas Plant (MGP) site located at 10 West Main Street in Richmond, Indiana (Site). The Site is enrolled in the Indiana Brownfields Program and is assigned site number 4980004. The groundwater remediation and site capping efforts are being completed at the request of the Indiana Department of Environmental Management (IDEM) Brownfield Section in order to secure United States Environmental protection Agency (US EPA) approval and maintain Brownfield and Indiana State Revolving Fund (SRF) loan eligibility for these activities. The Brownfield redevelopment program for this Site includes installation of a recreational pedestrian walk and bike trail for the citizens of Richmond. These activities are also associated with a larger sewer improvement project which results in SRF eligibility. The City has an approved Remedial Action Work Plan (RAWP) to address source areas and chemicals of concern (COCs) in the tar well area, basement area, and SB-14 area of the Site. A targeted removal action for these known source areas is presented in the existing RAWP and is currently scheduled for September 2012. The City is currently undertaking Cleanup Efforts to Define the Plume of COC impacted groundwater and to develop the remedial strategy to reduce and/or destroy the COC mass in the plume. The additional efforts specified in this proposal include design of an impermeable cap for the site following soil removal in the tarwell, basement, and SB-14 areas and development of bid specifications for the groundwater remediation and capping program in the time frame required to secure Brownfield and SRF funding. EXHIBIT Pd 5 0q. AECOM Development of Bid Specifications Bidding Services Former MGP Site Richmond, Indiana Summary of Previous Site Activities Site investigations were conducted at the Site between 1994 and 2011 to delineate soil and groundwater impacts associated with the former Richmond MGP Site through means of records searches, subsurface structure identification, local hydrogeological investigations, surface and subsurface sampling, installation of groundwater monitoring wells, and laboratory analysis of soil and groundwater samples. Information and findings from previous Site investigative efforts is provided in a number of documents as summarized in section 1.2.1 of the RAWP. The results of these investigations provided the data used to delineate source areas in soil. This information was utilized to prepare the approved RAWP in November 2011. Following the initiation of the RAWP, the IDEM Brownfield representatives requested that the City's cleanup efforts include remediation of groundwater by reduction and/or destruction of COC mass in the plume and the installation of a permanent site cap following source removal activities. As noted above, the City is currently completing Cleanup Efforts to Define the Plume and developing a remedial program. This remedial program and associated cost information will be provided to the IDEM Brownfield representatives by August 27, 2012. The IDEM Brownfield representatives have also requested that a cost estimate for cap installation also be provided by September 1, 2012. AECOM's proposed scope of work for this project includes the cap design and submission of an engineer's cost estimate to the IDEM Brownfield representatives in order to maintain funding eligibility. This proposal also includes costs for developing bid specifications for both the groundwater remediation program and the cap installation as well as bidding services on behalf of the City with regard to these specifications. These activities and associated schedule and cost information are presented below. ' Scope of Work AECOM's scope of work for cap design, developing bid specifications and providing bidding services will consist of the following tasks: Task 100 Cap Design • Cap Design • Develop Cap Installation Cost Estimate • Submit Cost Estimate to IDEM Brownfield Representatives Task 200 — Bid Specifications • Develop Cap Specifications • Develop Groundwater Remediation Specifications Task 300 — Bidding Services • Bid Advertisement & Distribution • Conduct Pre -Bid Meeting • Bid Evaluation Task 400 -- Brownfield and SRF Grant Coordination A more detailed description of each of these tasks is provided below. EXHIBIT PAGE 0 AECOM Deveiopment of Bid Specifications Bidding Services Former MGP Site Richmond, Indiana Task 100 — Cap Design Cap Design in accordance with IDEM request, AECOM will prepare the design for a cap to be placed over the former MGP site following source removal activities in the tar well, basement and SB-14 areas. Based upon our existing site knowledge and remedial objectives, AECOM is evaluating the installation of an impermeable clay cap across the entire site and extending approximately 10 feet to the west of the Site to cover impacted soil recently discovered during the groundwater investigation. Conceptually this cap will be 2 foot (ft) in thickness following compaction to 96% of proctor value. It is anticipated that the cap will follow the site grade as modified during the source removal activities. Following installation, the cap will be covered with approximately 6 inches (in) of topsoil and seeded with grass to match the surrounding recreational areas. Cap Installation Cost Estimate Following completion of cap design, AECOM will develop an engineer's estimate for the installation of the cap. This cost estimate will include all materials, supplies and contractor cost estimates and be of sufficient detail to accurately reflect costs for Brownfield and SRF loan consideration. Once complete, this cost estimate will be forwarded to the City for review and comment. AECOM will incorporate one set of comments into a revised cost estimate letter which will be returned to the City for submittal to the IDEM Brownfield representatives. At your request, AECOM will finalize this letter and forward it to the IDEM Brownfield representatives on the City's behalf. In either case, it is our understanding that the cost estimate must be submitted to the IDEM Brownfield representatives by September 1, 2012. Task 200 -- Bid. Specifications Develop Car, Specifications Once the cap design is complete, it will be incorporated into a specification for contractor bidding purposes. This specification will be developed in the same format as the previous site specific bid specifications completed by AECOM for the source removal project to be completed in September. This specification will include the same front end documents previously provided by the City and supplemented with the newly developed cap design considerations and the most current Common Construction Wage Scale for Wayne County, Indiana. Upon completion, a draft set of specifications will be provided to the City for review and comment. Subsequently, AECOM .%,iil prepare one final document incorporating the City's revisions and comments for issue by October 15, 2012 to meet the SRF eligibility scheduling requirements. Develop Groundwater Remediation Specifications Specifications for the groundwater remediation program will be prepared concurrently with the cap specifications. The groundwater remediation specifications will be developed by AECOM based upon the results of the current groundwater investigation. It is likely that this remedial program will involve an injection program to reduce contaminant mass and subsequent groundwater sampling to monitor the remedial progress. The groundwater remediation specifications will be combined with the cap specifications into a single document for the comprehensive site remediation activities. This document will be completed by October 15, 2012 to maintain SRF funding eligibility. EXHIBIT PAGE _�LOF _ AECOM Development of Bid Specifications Bidding Services Former MGP Site Richmond, Indiana Task 300 — Bidding Services Bid Advertisement and Distribution Following completion of the bid specifications and in a time frame mutually agreed upon with the City and funding source representatives, AECOM will advertise the bid and arrange for the distribution of the bid specifications to prospective bidders. AECOM will directly distribute the bid specifications to contractors selected by the City based upon disadvantaged business status, previous experience with the City and AECOM recommendation. In conjunction with this notification, AECOM will utilize Repro Graphix, Inc. of Indianapolis to advertise and distribute the specifications to additional interested bidders. Conduct Pre -Bid Meetin At the date and time noted in the specifications, AECOM will conduct a pre -bid meeting with prospective bidders. This meeting will include a summary presentation in the Community Room on the third floor of the Richmond Municipal Building (or City specified alternative location) followed by a Site walk. AECOM recommends that this be a mandatory meeting and will record attendance. In addition to summarizing the bid and Site conditions, AECOM representatives will answer questions with the caveat that our verbal response is not binding. AECOM's formal and binding response will be provided to written questions submitted by the prospective bidders. These responses will be provided by AECOM in writing and distributed through the Repro Graphix a -Plan Room website. Prospective bidder questions will be accepted and AECOM responses will be provided at the times noted in the specifications. Bid Evaluation All bids will be delivered to AECOM by the deadline noted in the specifications. Unless there are extenuating circumstances acceptable to the City, no bids will be accepted after this deadline. Upon receipt, AECOM will evaluate the bids for technical content, schedule and cost considerations. The result of this evaluation will be a list of pros and cons to each bid and a recommendation for award consideration. AECOM will provide the summary results and award recommendations to the City for consideration. The City will be responsible for final selection and project award to the selected bidder. The City will also be responsible for contract negotiation with the selected bidder. AECOM proposes to serve as the City's engineering and onsite representative for the implementation of the cap installation and groundwater remediation program. Costs for these services will be included in the engineer's design estimate for these activities. As indicated above, this design should be complete by August 27, 2012 and costs for these activities will be included with the final remedial program costs submitted to the IDEM Brownfield representatives at that time. Task 400 — Brownfield Grant and SRF Loan Coordination Throughout the course of this project, AECOM will support the City with third party correspondence, particularly with the IDEM and US EPA Brownfield representatives. This task may also include correspondence with other parties potentially involved with the remedial and Brownfield program such as public and private utilities, the Indiana Department of Transportation (INDOT) and the City Engineer and his consultants. Correspondence may also include written and verbal communication with local media outlets such as the Richmond Palladium Item Newspaper.
