JANONIS FROM: SUPERINTENDENT OF STREETS & BUILDINGS DATE: JULY 12, 2011 SUBJECT: SEALED BID RESULTS FOR THE REPAIR OF THE POLICE/FIRE HEADQUARTERS BUILDING PARKING DECK RAMP (NOT TO EXCEED $194,085) BACKGROUND In the current budget, staff has requested funds to repair the ramp portion of the existing Police /Fire Headquarters Building parking deck ramp. This ramp was constructed in conjunction with the rest of the Police /Fire Headquarters Building complex in 1993. The existing electric cable snow melting system failed within 10 years of construction and has required numerous repairs. Presently, it is not repairable. In order to control the accumulation of ice and snow on this incline, Public Works crews must mechanically apply salt and de -icing agents at frequent intervals during the winter season. Additionally, the garage access control equipment, ramp lighting, and automatic overhead door are also inoperable; requiring complete replacement. The proposed repair work includes selective demolition of the existing concrete ramp, installation of a new hydronic snow -melt system, replacement of the access drive and the ramp surface topping, and installation of a new access control system. The Village hired Desman Associates of Chicago, Illinois to design and prepare the bid documents, oversee the bid opening and supervise construction of the project. Desman is an architectural engineering firm that specializes in parking structures. The performed design and construction management services for the Village Hall Parking Deck project. BID RESULTS Sealed bids were opened at 1:00 P.M. on June 27, 2011 for proposed work. A bid notice was placed in the local paper and four concrete construction/restoration firms were invited to participate. Page two Repair of the Police /Fire HQ Building Parking Deck Ramp (not -to- exceed $194,085) July 12, 2011 Two bids were received. The results are as follows: Bidder Bid Price Martam Construction Inc., Elgin, IL $ 176,441 Takao Nagai Concrete Restoration, Chicago, IL $ 309,528 Two additional bids were received: one late and one at Public Works. The contract documents instructed all bidders to submit their bids to the Viiiage Manager's Office at 50 South Emerson Street prior to 1:00 PM on June 27. Both of these bids were deemed non - responsive and were returned unopened to the bidders. DISCUSSION The low cost proposal was submitted by Martam Construction Inc. of Elgin, Illinois. Martam has successfully completed a myriad of projects for the Village including bridge deck replacement, sewer repair and replacement, creek bank stabilization, water main replacement, and streetscape improvements. They were recently awarded the 2011 Combined /Sanitary Sewer Spot Repair contract. It is the opinion of staff that Martam is well qualified and sufficiently experienced to successfully complete this project. The engineer's estimate of probable cost for this project was $156,169. However, this estimate was prepared in the initial design phase and the assumptions utilized were changed in the final bid documents. Specifically, the initial design only required partial removal of the concrete slab on- grade; the final bid documents stipulated complete replacement. Additionally, the access control system and the duty rating of the overhead door are more robust than initially proposed. It is the opinion of staff that these differences in bid requirements satisfactorily explain the variance between the engineer's estimate and the low bid. Sans these changes, it is probable that Martam's bid would approximate the engineer's expectations of cost. Staff recommends including a 10% contingency fee in the award of this project. This contingency would be reserved for solutions to unanticipated conflicts that arise during the demolition or construction processes. In this instance, the total recommended award would be $176,441 (bid) + $17,644 (10% contingency) _ $194,085 (recommended total award). RECOMMENDATION Staff recommends accepting the lowest cost proposal as submitted by Martam Construction Inc. of Elgin, Illinois for repair to the Police /Fire Headquarters Building Parking Deck Ramp in an amount not to exceed $194,085. Sufficient funds for this proposed project exist in the current budget. � Paul Bures Superintendent of Streets & Buildings PB c: Director of Public Works Sean P.
