Max Hicks, PE, Director AGENDA ITEM EDITION _....j-;)- I Date: June 10, 2002 To: The Honorable Bob Young, Mayor Members of Commission Honorable Andy Cheek, Chairman of the Engineering Services Committee Through: George R. Kolb, Administrator From: ~N. Max Hicks, Director Augusta Utilities Department Re: Project 60110: Rae's Creek Relief Sewer Caption: Approve a proposal from Cranston, Robertson & Whitehurst, P.C. to provide design services for the Rae's Creek Relief Sewer Project. Background: The replacement of the Rae's Creek Trunk Main began in the early 1990s when a large diameter sewer pipe was installed across the Augusta National Golf Club. In 1996 the Utilities Department obtained funding from the sale of bonds designated for capital improvements to the water and wastewater systems. Funded by the 1996 Bond Issue the Augusta Utilities Department began systematically replacing portions of the trunk line showing evidence of inflow and infiltration in the upper reaches of the Rae's Creek Basin. The need to increase the pipe size of the remainder of the trunk sewer was anticipated due to the previous replacement projects; and a route study was done in association with the 2000 Bond Issue. Analysis: To handle the flows from the Rae's Creek Basin the stretch of sewer from the Augusta National Golf Club to Chaffee Park should be replaced at this time. Approving this proposal will allow Cranston, Robertson & Whitehurst, P.C. to begin design on this stretch of trunk main. Financial impact: $454,737.50 from the 2000 Bond Issue, under account number 509043420- 5212115/80160110-5212115. Alternatives: Disapprove the proposal from Cranston, Robertson & Whitehurst, P.e. and advertise for open proposals to design the final section of the Rae's Creek Trunk Sewer Main in Augusta Recommendation: We reconmi.end approving the proposal from Cranston, Robertson & Whitehurst, P.C. to provide design services for the Rae's Creek Relief Sewer Project.

Georgia 30901 Attention: Jim Rush Re: Rae's Creek Relief Sewer Bond Project No. 60110 Our File No. 2000-413 Dear Jim: In accordance with your request, we are pleased to offer the following proposal for accomplishing the necessary surveying and engineering services for the design of a sanitary relief sewer along Rae's Creek from the end of the existing 48 inch sanitary sewer in Willow Creek Subdivision to the new sanitaIy sewer pump station near Chafee Park. GENERAL The Rae's Creek Relief Sewer will involve the construction of approximately 600 linear feet of 48 inch ductile iron pipe from Willow Creek Subdivision to the Augusta National property and approximately 12;500 linear feet of 54 inch ductile iron pipe from the Augusta National property to the recently constructed Chafee Park Pump Station. The proposed route of the relief sewer will be in accordance with Route B of the Engineering Report for the Rae's Creek Relief Sewer prepared by Cranston, Robertson & Whitehurst, P.C. and dated April, 2002. In general, the route will run along the north side of Rae's Creek from Willow Creek Subdivision to the Calhoun Expressway. At this point. the sewer will cross under Rae's Creek and then continue along the south side of Rae' s Creek and Lake Olmstead to the Augusta Canal where it will connect with the existing Rock Creek Trunk Line and then continue along the canal to the Chafee Park Pump Station. The project will include connections, structures, an "inverted siphon" under Rae's Creek, borings under Georgia State Highways and ramps, and other necessary appurtenances. 96-Q3-92 16:23 CRANSTON ROBERTSON WHITEHURST .' '~ ID=7967228379 P93/95 .' - ..t .'. Mr. Jim Rush June 3, 2002 Page 2 SCOPE OF WORK As a supplement to the previously completed aerial topographic base map, the scope of work will include field surveys of the proposed sewer route in sufficient detail to locate the roads, fences, driveways, drainage structures, and all visible improvements along the route. These surveys will also include locating existing utility lines based on field marks and maps furnished by the utility owners. These utilities will include pOWer, gas, water, sewer, telephone, and CATV. We will prepare the necessary plans, specifications, and contract documents for the sewer system route, including the required structures and appurtenances. Initially, we will prepare preliminary route layouts for your review and approval. Upon your approval of the general route, we will perform the detailed route survey and prepare preliminary design plans showing horizontal and vertical alignments, structureS, and miscellaneous details for your review and comments. Based on your comments. we will prepare and submit final design plans and specifications for your review. Also, at this time, we will complete and forward any required utility permits, encroachment permits, wetlands permit and buffer variances to the appropriate federal or state governing authorities, and provide ancillary drawings as required for these permits. Drawings will be prepared in ink on mylar film at an appropriate scale. We can also furnish the drawings in AutoCAD computer disc format, if desired, at no additional fee. In the event of difference between the disc-reproduced drawing and the original tracing, the hard copy tracing will govern. We will also prepare plats for acquisition of any easement that may be required for the construction of the sanitary sewer mains. We propose to furnish the following bidding and construction phase services: preparing a schedule for bidding, preparing bidding documents. assisting you with securing bids from qualified contractors, advising you concerning the award of a contract, preparing contract documents subject to your approval, issuing a notice to proceed, making observations of the construction work as it progresses to observe the general quality, furnishing written reports of the observations made during each visit, coordinating with the project engineer and inspector provided by the City/CH2M Hill, administering appropriate progress meetings, issuing instructions to the contractor, reviewing shop drawings, reviewing the contractor's monthly applications for partial payment, detennining the amounts owing to the contractor, interpreting the contract documents and technical specifications, consulting as necessary with the City~County authorities and their representatives concerning their requirements, making a final inspection to detennine whether or not the work has been completed substantially in accordance with the plans and specifications, preparing digital construction as-builts from information provided by the contractor, and reviewing the contractor's application for final payment. 96-~3-92 16:24 CRANSTON ROBERTSON WHITEHURST -' .

Based on a construction cost estimate of $8,013,200.00, this fee represents 4.47 percent and reflects a credit of $50,485.00 for the concept and route study which was completed independently of this proposal. We have also included a fee for an additional bidding/construction phase should it be necessary to let more than one construction contract and a fee for the estimated number of easement platS required for the construction of the relief sewer. A preliminary construction cost estimate is attached hereto for your convenience and the total fee is broken down by project phase as follows: Preliminary Route Layout (5%) $ 17.909.50 Preliminary Design and Route Surveying (40%) $ 143,276.00 Final Design and Centerline Survey (30%) $ 107,457.00 Bidding Phase (5%) $ 17,909 .50 Construction Phase (20%) $ 71.638.00 Base Fee $ 358,190.00 · Additional Bidding & Construction Phase $ 89,547.50 (Only required if project is phased) Easement Plats (Estimate 20 @ $3S0.00/ea) $ 7,000.00 Total Fee $ 454,737.50 -Should the time frame for the: two consuuclion contnlCtS occur simultaneously, then this fee could be reduced slightly. We expect to submit periodic invoices covering the design work as it progresses and to receive payment within fifteen days thereafter. ' 96-93-92 16:24 CRANSTON ROBERTSON WHITEHURST .
