Meeting December 7, 2021 - REGULAR MEETING OF THE MOUNT PROSPECT •A'D Fiscal Impact true Dollar Amount $191,294.00 Budget Source Water & Sewer Enterprise Fund Category CONSENT AGENDA Type Consent As part of the 2017 Water and Sewer Rate Study, renewal and replacement of the Villages water mains, fire hydrants, valves, and other distribution system appurtenances was identified as a high priority. One outcome of this study was an increase in funding for water main replacement projects. A primary goal of accelerating the pace of water main replacements is to reduce the life cycle of water mains from an unsustainable 600 years to a more pragmatic 130 years. 2018 was the first year of an accelerated water main replacement schedule supported by new water and sewer rates. Combined, in the first four (4) years of this accelerated program, the Village has replaced 17,855 feet of water main and rehabilitated an additional 6,154 feet of water main through the cured -in-place pipe lining process. In 2021, the water main replacement project included Wille Street, Prospect Avenue, William Street, George Street and Connie Avenue. These sections of water main have had multiple breaks within the last 10 years and the water main size was increased from 6" diameter pipe to 8" diameter pipe to improve flow and pressure. Also in 2021, Staff rehabilitated 2,284' of existing 6" main on Can Dota Avenue, 8" main on Edward Street, See Gwun Avenue, Hi Lusi Avenue, Elmhurst Road, Main Street, Emerson Street, School Street, William Street, Edward street, 10" main on Emerson Street and Kenilworth Avenue and the 12" main on Prospect Manor Avenue. These pipe segments are all crossing underneath Weller Creek and the Union Pacific Railroad. They were all successfully rehabilitated through means of cured -in -place -pipe lining. In 2022, staff seeks to replace 10,923' of existing 6" and 8" water main. The locations include Deneen! Small and Straton lane, the 1800 and 1900 blocks of Estates Drive, Waverly Avenue from Lonnquist Blvd. to Golf Road, Audrey Lane from Connie Lane to Bonita Avenue, Hatlen Avenue from Estates Drive to Lonnquist Blvd., Pendleton Place from We Go Trail to Kenilworth Avenue, Waverly Place from Pendleton place to Milburn Avenue and Cottonwood Lane from Busse Road to Redwood Drive. These pipe sections are scheduled for replacement due to multiple water main breaks within the last 10 years. Plans are to abandon the existing water main in place and installing new water main adjacent to the old one. The water main size will also be increased from 6" to 8" to improve flow and pressure. The attached location map depict the proposed project area. • - • • • . •mm To design these improvements, staff requires technical assistance from a qualified civil engineering consultant. Accordingly, staff prepared a detailed request for proposals (RFP) necessary to solicit these services. A copy of this RFP is enclosed. Consulting engineers were asked to submit a technical proposal detailing the firm's background, key personnel, and approach to the project. In addition, each firm was also asked to submit a separate cost proposal indicating work effort anticipated and a not -to -exceed fee. The required scope of work includes topography and field data collection; preparation of plans and bid documents; meetings and obtaining all necessary regulatory permits. RFPs were distributed to five (5) local engineering firms and publicized on the Village's Demandstar website. Ten (10) technical proposals and ten (10) cost proposals were received. Each proposal was evaluated based on the background of the firm, related project experience, proposed services and scope of work, schedule work effort and proposal content. Each firm received a point ranking (total points = 100) for each criteria. Table 1 (attached) summarized this analysis. The highest rated firm is Thomas Engineering (Thomas) of Oak Brook, Illinois. Thomas Engineering's proposal provided numerous examples of successful water main replacement projects similar in scale and scope as the proposed work. Examples cited were water main replacement projects in the City of West Chicago, Morton Grove -Niles Water Commission, and the City of Wheaton. A copy of Thomas' technical proposal is enclosed. Notably, Thomas Engineering was hired by the Village of Carol Stream for Phase I, II and III of the $3.2 million dollar water main replacement on Schmale Road. The scope of services consisted of alternative analysis and determination of the preferred alignment for removal and replacement of approximately 7,000 feet of 10" and 12" deteriorating water main. The work included water main abandonment, water service line replacement, new fire hydrants, valves, horizontal directionally drilled water main, boring and jacking, storm sewer and sanitary sewer replacement, driveway replacement, pavement patching and parkway restoration. Schamle Road is a four lane highway consisting of many business and apartment complexes. Thomas Engineering procured all necessary permits as part of the design process. Thomas Engineering has not performed water main replacement work for the Village of Mount Prospect in the past. However, staff contacted references from municipalities that have contracted with Thomas Engineering on similar projects and received positive feedback. It is the opinion of staff that Thomas Engineering has sufficient skills, experience, and resources to successfully complete this proposed project. In addition to the technical proposal, each firm was also asked to submit a cost proposal as well. Table 2 (attached) summarizes staff's analysis of these submittals. The lowest cost proposal was also submitted by Thomas Engineering of Oak Brook, Illinois. A copy of the firm's cost proposal is enclosed. It is the opinion of staff that Thomas Engineering understands the proposed project, has prepared a thorough proposal based on extensive experience, requested a reasonable fee, and is well qualified to perform the work. Notably, the assigned work effort (1,334 hours) is reasonable and the requested fee ($173,904 or $130/hour) is competitive. Staff recommends including a 10% contingency in the project award for the proposed contract because time spent on construction engineering and inspection can vary due to circumstances beyond the engineering consultant's control. For example, contractor delays, material availability and inclement weather are all parameters that can lengthen anticipated construction time. Inclusion of a 10% contingency ($17,390.00) will increase the project award from $173,904.00 to $191,294.00. Alternatives 1. Accept proposal for 2022 Water Main Rehabilitation Design and Construction Engineering Services as submitted by Thomas Engineering of Oak Brook, Illinois in an amount not to exceed $191,294.00. 2. Action at the discretion of the Village Board. Staff recommends that the Village Board accept the proposal for 2022 Water Main Rehabilitation project design and construction engineering as submitted by Thomas Engineering of Oak Brook, Illinois in an amount not to exceed $191,294.00.
