Max Hicks, Director Augusta Utilities Department Date: December 14,2000 December 27, 2000 Committee Meeting Re: Concept Phase for Project 50130:Butler Creek Collector Extension Caption: Approve a proposal from W.R. Toole Engineers, Inc. in the amount of$10,350 to develop a conceptual design for a collector extension of the Butler Creek Sewer Basin into the Bel-Air Hills Estate subdivision. (Funded by Account Number: 509043420/521211580150130/5212115) Background: For a number of years there have been requests by residents of the Bel-Air Hills community to extend public sewer further into the Butler Creek Basin and into their subdivision. The funding for this extension has been budgeted for in the Augusta Utilities 2000 Bond Issue Capital Improvements Program. A conceptual phase is required to determine pipe routing and sizing requirements to reliably serve the area characterized as the Bel-Air Hills Subdivision. Analysis: Accepting this proposai will provide the necessary funding to develop a conceptual layout for the Butler Creek Collector Extension into the Bel-Air Hills Estate subdivsion. This extension analysis will allow preliminary routes and pipe sizes to be determined for this project. Financial impact: $10,350 from the 2000 Bond Issue, under account number 509043420/5212115 80150130/5212115. Alternatives: No practical alternatives Recommendation: We recommend approval of W.R. Toole's proposal for engineering services in the amount of$1 0,350.00 (Account Number: 509043420/5212115 80150130/5212115) for the conceptual phase of the Butler Creek Interceptor Extension.

AUGUSTA, GEORGIA 30903 W R Toole Engineers, Ine Civil Engineering - Planning - Land Surveying December 13,2000 Augusta Utilities Department 360 Bay Street, Suite 180 Augusta, GA 30901 Attention: Program Management Team Mr. Larry Scott, Program Manager Subject: Proposal for Engineering Services Project No: 50130 - Butler Collection Extension TE Proposal No. POO-151 Dear Mr. Hicks: 706.722.4114 (VOICE) 706.722.6219 (FAX) W.R. Toole Engineers, Inc. appreciates this opportunity to provide you EMAIL: WRTOOLE@WRTOOLE.COM with a proposal for professional services for the Butler Creek Collection Extension Project. Due to the complexity of this project, W.R. Toole Engineers proposes that the project be broken down into several tasks with separate deliverables and fee structures. This proposal outlines the different tasks anticipated for completion of the project and also provides a compensation schedule for the first task. Upon completion of the first task, additional proposals will be submitted regarding the remaining tasks. TASK 1- CONCEPTUAL PLANNING Preliminary proposed routes for the Butler Collector Extension Sanitary Sewer system were provided in the supplied request for proposals. Task 1 services will include confirmation of these routes and verification of the pipe sizes necessary to provide sanitary sewer service to the Bel Air Hills Subdivision. The deliverable for this task will be an engineering report outlining proposed recommendations, an opinion of probable construction cost, design assumptions, potential design conflicts, environmental concerns, and a Richmond County GIS Map depicting.the project area with proposed sanitary sewer routes. Please note that Toole Engineers assumes Augusta Utilities will provide a digital copy of the Richmond County GIS data, POO-I 51 Collection Extension Butler Creek Proposal Letter.doc TASK 2 - WETLAND DELINEATION Following verification of the model information and approval of the concept plan by the Augusta Utilities Program Management Team, W.R. Toole Engineers will proceed with scheduling the environmental planning. Due to the proximity of the sanitary sewer routes to Butler Creek and its tributaries, we recommend delineation of wetlands prior to further design activities. Although some wetland areas cannot be avoided, there will be some circumstances when simply shifting the proposed sewer alignment a few feet left or right will reduce wetland disturbance. The deliverable for this task will be the delineation of the wetlands within the immediate project area. The actual wetland limits will be identified and flagged in the field, later to be located and mapped by surveying activities. W.R. Toole Engineers utilizes the sub-consultant services of Graves Engineering for wetland delineations. TASK 3 - SURVEYING & BASEMAPPING Concurrent with Task 1 and Task 2, W.R. Toole Engineers will provide GPS surveying services to provide horizontal and vertical control points within the project limits. These points will be tied into state plane coordinates and will provide control for the entire proj ect. The use of state plane coordinates will also allow for the construction documents to be inserted directly into the Richmond County GIS information which is also on the state plane coordinate system. With control points set, Toole Engineers will be available to immediately initiate field surveying activities upon completion of the wetland delineation. Utilizing the approved concept layout and the wetland flagging, the proposed sewer alignments will be surveyed in the field. The width of the route survey will depend on the surrounding site conditions. Undeveloped areas, adjacent to creeks, will only require a narrow survey to adequately show proximity to creek banks and wetlands. Developed areas will requrie a wide route survey to accurately locate residential structures, utilities, pavement sections, etc. Minor modifications to the proposed sewer alignments are anticipated during completion of the field survey as site conditions may warrant shifting alignments to avoid wetlands or other previously unidentified structures. Any major alignment modifications will immediately be brought to the attention of the project management team and a determination will be made as to whether or not the concept plan needs to be revised and reviewed. The deliverable for this task will be a completed base map provided in both a hard copy format and in a digital format (AutoCAD Version 14) if requested. POO-151 Collection Extension Butler Creek Proposal Letter.doc TASK 4 - PRELIMINARY ENGINEERING DOCUMENTS Following completion of Task 3, Toole Engineers will initiate services for preparation of construction documents. The set of construction plans will include a plan/profile of the sewer and any necessary construction details. In addition, preliminary easement maps will be compiled. The deliverables for this task will be a set of construction plans, a preliminary quantity take-off, an opinion of probable construction cost, and compiled easement maps. Field staking of proposed manhole locations will also be included in Task 4 services. TASK 5 - ENVIRONMENTAL PERMITTING Depending on the complexity of the project, environmental permits will be prepared concurrently with Task 4 or following Task 4. It is anticipated that, at a minimum, wetland permits will be required. W.R. Toole Engineers recommends that Augusta Utilities initiate preliminary meetings with the USCOE (David Crosby) at the earliest convenience to discuss all of the projects to be completed within this program. This early coordination effort will greatly increase the approval rate for the projects and will significantly decrease the review periods for submitted permit applications. In addition, it may be in the best interest of Richmond County to set-up a large scale mitigation plan for future wetland disturbances in the form of wetland banks, wetland credits, etc. The deliverable for Task 5 will be an approved permit from the USCOE. W.R. Toole Engineers utilizes the sub-consultant services of Graves Engineering for environmental permitting. TASK 6 - FINAL ENGINEERING DOCUMENTS Upon review and approval of the preliminary engineering documents by the program management team, Toole Engineers will make any necessary revisions and fmalize the engineering documents. The deliverables for this task will be five (5) final sets of construction plans, five (5) final sets of compiled easement maps, and five (5) sets of bid documents including quantity take-offs and technical specifications. Additionally, Task 6 services will include final field staking of the proposed manhole locations. TASK 7 - PROJECT BIDDING Task 7 services include support during the advertising and bidding of the projects. Bid packages will be provided to all bidders for a fee to be determined based on reproduction costs. Toole Engineers will also attend a pre-bid meeting as necessary, will attend the bid opening, will review all bids, and will make recommendations' on the low bidder. The POO-ISl Collection Extension Butler Creek Proposal Letter.doc deliverable for this task will be a tabulated bidders list, confIrmation of the low bidder, and a letter of recommendation for award. TASK 8 - CONSTRUCTION INSPECTION W.R. Toole Engineers is available for part-time and full-time construction inspection. Deliverables for construction inspection include daily, weekly, and monthly reports, pay request reviews, and documentation of field changes and change orders. TASK 9 - AS-BUILT DRAWINGS W.R. Toole Engineers can provide as-built drawings in digital format by two methods. The first method includes providing a drafting service by modifying the original construction documents with information provided by the contractor on a "red-lined" set of plans. The digital copy of the modified plans and the red-lined set of plans are then submitted to Augusta Utilities. This method provides no guarantees as to what has actually been constructed in the field. The second method would include surveying services to physically locate the new manholes as constructed and provide invert elevations on all pipes. The deliverable for method two would be a digital copy of the sewer system layout as located in the field overlayed on top of the original construction document. CO~ENSATIONSCHEDULE The following compensation schedule is separated per the tasks .outlined above: T ASKl: Professional services for Task 1 will be completed. for a lump sum fee of$10,350.00. TASK 2: Due to the unknown limits of potential wetlands within the project area, a separate compensation schedule will be provided following approval of the Concept Plan ( Task 1). TASKS 3,4 ,6, & 7: Upon approval of the Concept Plan (Task 1) a separate compensation schedule will be prepared outlining fees for these tasks. TASK 5: Following approval of the Preliminary Engineering Plan (Task 4), a proposal and fee structure will be provided which outlines the steps to obtain an environmental permit. POO-151 Collection Extension Butler Creek Proposal Letter.doc . . TASK 8: An hourly rate schedule and detailed scope of work will be provided for these optional services as requested by the program management team. TASK 9: A separate proposal will be provided depending on which of the two as-built methods is requested. TIME SCHEDULE As per this proposal, Task I services will be completed prior to authorization of further services. W.R. Toole Engineers will submit a preliminary engineering report for Task 1 within four (4) weeks of obtaining notice to proceed and receiving county GIS information in digital format. It is anticipated that review of the engineering report will be completed by the program management team within approximately four (4) weeks of submittal. Following the review, the engineering report will be revised and finalized within two (2) weeks. Scheduling for remaining tasks will be determined in subsequent proposals.
