Brand Superintendent of Utilities City of Oshkosh 215 Church Street Oshkosh, WI 54901 Subject: Proposal for Design, Bidding and Construction Administration Services for the Four Sedimentation Basins,Spool Repair on 1984 Lift Station,and Repair of the Filtration Sludge Line at the City of Oshkosh Water Treatment Plant in Oshkosh,Wisconsin AECOM Proposal No.OPP-228528 Dear Mr. Brand, AECOM Technical Services, Inc.(AECOM)presents this proposal for professional engineering services related with Design, Bidding,and Construction Administration services for the repair of Four Sedimentation Basins, repair of the spool on the 1984 High Lift Station,and repairs to the filtration sludge line at the City of Oshkosh Water Treatment Plant in Oshkosh,Wisconsin. This proposal presents our understanding of the project,our proposed scope, and fee estimate. Project Understanding Sedimentation Basins We understand the construction of the basins was completed in November of 2000. During construction a concrete admixture caiied "Xypex"was added to the freshly mixed concrete to fill in smaii voids as a result of cracking. Since construction has been completed,the walls and slabs have cracked and the walls have been actively leaking and other types of concrete distress such as spalling and failed expansion joints have occurred. In April—May 2012,AECOM completed a condition assessment of the four sedimentation basins at the Oshkosh Water Treatment Plant(WTP)and issued a letter report dated May 11, 2012, that provided repair recommendations. We understand that the City of Oshkosh is considering having AECOM's recommended concrete repairs performed to the four sedimentation basins in 2014. In addition,we understand the basin repairs will occur in two phases. Two basins will be repaired in early spring and the remaining two will be repaired in late fall of 2014. 1984 High Lift Station We understand the spool on the one of the water transfer lines is leaking and the City wishes to have it repaired. This repair work will be bid out with the Sedimentation Basins repairs. This document includes proprietary data that shall not be duplicated,used or disclosed outside City of Oshkosh for any purpose other than to evaluate this document.This restriction does not limit City of Oshkosh's right to use information contained in this document if it is obtained from another source without restriction. OPP-228526_WTP Sedimentation Basins and Filtration Slude Line Repairs Proposal.docx AECOM 2 Filtration Sludge Lines Fasteners We understand that the bolts and nuts associated with the filtration sludge lines are deteriorating. We have been requested to bid out replacement of all bolts and nuts with stainless steel fasteners as part of the bidding specifications and plans. The following is a breakdown of our proposed scope of services and associated costs. Scope of Services The following briefly describes our proposed scope of services to prepare construction-level documents, obtain bids, and assist with construction oversight. Task A: Prepare Repair Design and Bidding Construction Document This proposal assumes one plan set and project manual will be prepared to represent the necessary construction work for the sedimentation basin, 1984 High Lift Station Spool, and Filtration Sludge line fastener repairs. To prepare the construction documents,AECOM will: • Hold a project review meeting with the project stakeholders,as defined by the City. The purpose of this meeting is to confirm previous recommended repairs and project expectations. • Prepare a preliminary construction plan set and a project manual at 90%completion level for City and stakeholder review. Hold up to one review meeting to obtain comments and revisions for drawings and specifications. • Prepare a final plan set and project manual suitable for bidding. The project manual will contain the bidding and contract requirements, utilizing the City's standard documents and concrete repair industry standards. AECOM will provide project specific specifications for items the City Standard Specifications do not address. • Prepare opinions of probable cost at 90%and final completion level for City review. • The City will advertise for bids and place the bidding documents on Quest Construction Data Network LLC.—ebidDoc. • The City will provide construction drawings and as built information related to the spool and sludge line repairs. Deliverables: PDF copies of the plan set and project manual and opinions of probable cost at 90%and final completion level for City Review. Task B: Bid Administration • Attend a pre-bid conference. • Answer bidder's questions and prepare up to one Addendum to the project specifications and documents. We assume the City will advertise for bids and place the bidding documents on Quest. • Attend the bid opening,and assist with recommending a contractor. Use or disclosure of data contained on this sheet is subject to the restriction on the first page of this document. K:\PROPOSAL\City of Oshkosh\OPP-228526_WTP Sedimentation Basins and Filtration Sludge Line Repairs\OPP-228526_WTP Sedimentation Basins and Filtration Slude Line Repairs Proposal.docx AECOM 3 Deliverables: Draft plan set and bidding documents for City review three hard copies. Final bidding documents will be provided electronically and three hard copies of the final Plan Set will be furnished to the City. AECOM will prepare a memorandum with recommendations regarding contractor selections based on the bidding results. Task C: Construction Documentation—Sedimentation Basins,Spool and Sludge Line Repairs AECOM proposes to follow a limited quality assurance program during execution of the repair work to spot check for conformance with our design for the repair of four sedimentation basins. At this time,we estimate an 8-week construction schedule(2 weeks/basin). We anticipate making five field visits per week during the construction work. We anticipate spending a maximum of 4 hours on-site for each of the site visits to spot check the repair work and attend construction meetings,as required. Also,we anticipate two(8)additional hours of engineering time per week for the preparation of daily field reports and other engineering services in connection with the repairs. The exact amount of additional hours for engineering will depend on our findings during our site visits and the amount of time required for addressing unforeseen conditions uncovered during the construction work. The proposed program will include the following and assumes an 8-week construction schedule: 1. Serve as the liaison with the City and contractor, and assist them in understanding the intent of the contract documents. 2. Prepare and lead a pre-construction meeting at the site. 3. Review contractor's submittals and material samples for conformance with contract documents, and notify the City of their availability for examination and non-conformance. 4. Conduct site observations of the work in progress,determine if the work is generally proceeding in accordance with the contract documents and that completed work conforms to the contract documents. We estimate to make a maximum of 8 site visits(4 hours portal to portal)to perform spot check observations of the preparation work and installed repair materials. We will issue a site visit report to City of Oshkosh after each site visit to document meeting minutes,site observations, and construction related issues that may arise during each site visit. 5. Confirm adequacy of the completed repair work compared to Construction Documents and the completed repair quantities. 6. Prepare necessary field modifications and change orders in accordance with instructions of the City. Field modifications are conditions that require no adjustment on the contract cost or time of completion. Change orders require modification of cost and/or time of completion. 7. Transmit to contractor the City's clarifications and interpretations of the contract documents. 8. Maintain correspondence files, reports of job conferences,shop drawings and sample submissions, reproductions or original contract documents including all addenda,change orders,field orders, and additional drawings issued subsequent to the execution of the contract. 9. Where applicable,witness field testing of the facilities furnished under the contract to assist in determining conformance with the contract documents. 10. Review applications for payment from the contractor for compliance with the established procedure for their submission, and forward with recommendations to the City noting particularly relation to the schedule of values,work completed, materials and equipment delivered at the site, but not incorporated in the work. Use or disclosure of data contained on this sheet is subject to the restriction on the first page of this document.

For each Sedimentation Basin,conduct a final inspection in the company of the City and contractor, and prepare a final list of items to be completed. 12. Before AECOM issues the"Certificate of Substantial Completion,"submit to the contractor a list of observed items requiring completion or correction. 13. Provide photo documentation throughout the construction period. 14. Provide vehicles, necessary equipment,and material for inspection. We will assign an experienced engineer/technician to provide construction observation services. We will assign a project manager to coordinate the field observations and testing and to provide support and consultation on construction issues that cannot be readily resolved in the field. If the construction schedule extends beyond the estimated 8-week construction schedule,we will request, in writing, a change order for additional services for the duration of the remaining construction schedule. AECOM proposes a team comprised of Paul Timm, Project Manager, Chris Rogers, Field Staff and Terry M. Refai, P.E.,S.E., Principal Structural Engineer and Nick Dutler, P.E. as Design Lead and Project Structural Engineer. Deliverables: As-Record Plan Set prepared from site observations, and contractor's red-lined set. No other site features will be surveyed,unless specifically requested by the City. Project Schedule The following schedule has been prepared assuming a construction start of September 2013. If an expedited schedule is desired,we can discuss how this can be accommodated. Project Kickoff Meeting with Stakeholders: End of December 2013 100% Review Plan set and Project Manual: Early February 2014 Final Construction Documents for bidding: End of February 2014 Bid Opening: Mid-March 2014 Preconstruction Meeting and Contractor Mobilization: Mid April 2014 Construction(8 weeks): May 2014 through January 2015 Project Closeout: February 2015 Schedule is based on the assumption that the 1984 High Lift Spool and Filtration fastener portions of the project are completed simultaneously and in May of 2014 during the first phase of Sedimentation Basin repair.
