JANONIS FROM: WATER & SEWER SUPERINTENDENT DATE: APRIL 29, 2014 SUBJECT: BID RESULTS FOR GEORGE STREET SOUTH SANITARY RELIEF STATION PROJECT (CIP) - ($160,427) Background In the current budget, funds have been requested to rehabilitate the George Street South sanitary relief station. This pumping facility is used to provide relief to the Village-owned sanitary sewer system in the event that the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) interceptor sewer becomes surcharged. The MWRDGC interceptor sewer system accepts wastewater from Mount Prospect sewers and transports it to treatment plants in Skokie or Des Plaines. During wet weather, interceptor sewers can become full thereby limiting the rate at which they can accept gravity flow from local Mount Prospect sewers. To mitigate the resultant surcharge conditions in our local sewers, relief pumping stations were installed in some neighborhoods. These stations help prevent the MWRDGC interceptors from backing up into local sewers. The George Street South Sanitary Relief Station is located in the George Street right-of- way south of Weller Creek. It was built in 1971 and has been repaired over the years as needed. This station provides sanitary sewer relief for the area from Golf Road to Weller Creek, bounded by South Albert Street on the east and South William Street on the west. Staff created detailed bid specifications and bidding materials necessary to procure the needed retrofits, services and equipment. The improvements include the installation of a complete replacement pump station with new pumps, guide rails and controllers, along with all associated wiring and other electrical control equipment. The standby emergency generator was installed in 2010 is in excellent condition; it will not be replaced as part of this project. Page 2 of 3 Bid Results for George Street South Sanitary Relief Station Project (CIP) ($160,427) April 29, 2014 Since these stations are permitted by the MWRDGC, staff worked closely with a consulting engineer to ensure that the project meets all permitting requirements. This work required that staff maintain the same horsepower rating for all new pumps. Staff also recommended standardizing pumps and other equipment between the various stations. Staff feels that this is an important aspect of the overall rehabilitation. This standardization of components allows staff to stock fewer spare parts as the pumps and their fittings now will be interchangeable between stations. In the past, pumps could not be interchanged in emergencies or required an extensive effort to accommodate the various different flanges or other fittings needed to make them work for more than one station. The Village owns and maintains eight (8) sanitary relief stations and two (2) sewage lift stations. All of the sanitary relief stations operate in a manner similar to the George Street station. In future years, staff intends to rehabilitate all of the sanitary relief and lift stations in the Village-owned wastewater collection system. One (1) sanitary relief station has already been rehabilitated (George Street North); 7 relief stations and both lift stations remain pending. Bid Results On Monday, April 28, 2014 at 1:00 P.M., sealed bids for the project were opened and read aloud. Thirteen (13) firms were solicited and public notice was placed in a local newspaper as required.Eight(8) bids were acquired by vendors. Two (2) bids were received. The bid opening result was as follows: ¼£± Bidder ±ÐÃªËñ±±Ãª£Ã x30/Ë,01È44 1 Marc Kresmery Construction ±ÐÃªËñ±±Ãª£Ã x2.-Ë1/4È44 2 Martam Construction Discussion Staff reviewed the bid submittals and finds that the bidders satisfy the bid documents, are both qualified to perform the work, and are proposing similar equipment. Marc Kresmery Construction of Elgin, Illinois has not worked with the Village in the past. The firm has recently constructed similar projects in several suburbs including Crystal Lake, Lake in the Hills, Naperville, St. Charles and Elgin. All references were verified and satisfactory. Page 3 of 3 Bid Results for George Street South Sanitary Relief Station Project (CIP) ($160,427) April 29, 2014 Staff finds that Marc Kresmery Construction of Elgin, Illinois is the lowest responsible bidder. The project is scheduled to be completed and fully operational by late September. The work is scheduled to occur in mid to late August. Since the existing station will be replaced under this contract, there is always the possibility of unforeseen issues arising during construction so staff is recommending the inclusion of a 10% contingency ($14,584). This would make the total award for this project as $160,427 (base bid of $145,843 plus the 10% contingency of $14,584). The engineer’s estimate for the replacement project was $177,000. Bid Recommendation I recommend accepting the lowest qualified bid for the George Street South Sanitary Relief Station Project as submitted by Marc Kresmery Construction of Elgin, Illinois at a cost not to exceed $160,427.00. Sufficient funds for this project are available in the current budget. Matt Overeem Water & Sewer Superintendent I Concur. Sean P.
