Memo 11.11 1111% - 4ASSO(I4AT -ES TRUE TO: Mayor Blesener & Members of the City Council FROM: Lee Elfering, City Engineer DATE: July 13, 2005 RE: City Hall Parking Lot Reconstruction The condition of the City Hall parking lot has been deteriorating faster than expected. The anticipated cause of the failures is possible natural springs and poor soils underneath the parking lot. The location of the worst deterioration is in the middle public parking area of the lot. In anticipation of future reconstruction of the lot, drain tile has been installed up the driveway as part of the Noel Drive Street reconstruction. Due to the street Contractor being in close proximity to the City Hall parking lot, we asked for a quote to reconstruct the entire lot, including adding drain tile and a 1 -foot subgrade correction. Quotes were also requested from two other Contractors to complete the work, but only one was received. Tower Asphalt is the prime contractor on the 2005 Street Reconstruction project and provided the lowest quote for the work. The two quotes for full parking lot reconstruction are as follows: Tower Asphalt $60,688.00 Frattalone Paving $75,754.60 Three options exist for the City. The first is that although the cost of the improvement is over $50,000.00, the work could be added by Change Order to the 2005 Street Reconstruction project. The second option would be to not do any of the parking lot work at this time and bid the project early next year in an attempt to receive a better price through more competitive bidding and more favorable bidding time next year. The third option would be to reconstruct only a portion of the lot. As stated previously the worst area of the lot is the middle section of the public parking area. We could remove the reconstruction of the City Employee side of the lot, and possibly the north end of the lot. I have spoken with Tower Asphalt and they indicated that the unit prices given would be honored if the City Employee lot portion was removed. They indicated they would want to review the amount that would remain if both the employee lot and north end of the lot were removed. Below is an estimate of the costs for each option if the unit prices hold. Full Lot Reconstruction Only the Public Parking Lot Only Middle portion of the Lot $60,688.00 $53,000.00 $43,500.00 Based on the options and costs provided, we would like direction from the City Council on how to proceed. 10062 Flanders Court NE, Blaine, MN 55449 — Ph: (763) 780 -0450 — Fax: (763) 780 -0452 C: \Documents and Settings \joel.hansen \Local Settings \Temporary Internet Files \OLK232 \Memo - 071305 -CC -City Hall Parking Lot.doc
