Home My WebLink About3/31/2004 - STAFF REPORTS (5) 31 DATE: March 2004 TO: City Council FROM: Director of Public Works/City Engineer PALM SPRINGS CONVENTION CENTER EXPANSION PARKING LOT .& STREET IMPROVEMENTS RECOMMENDATION: It is recommend that the City Council award contract to Contreras Construction Co., in the amount of $730,356.25, for Alternative Bid Schedule A, Alternative Deductive Bid Schedule C, Additive Bid Schedule D, and Additive Bid Schedule E for the Palm Springs Convention Center Expansion Parking Lot & Street Improvements, City Project 02-27, subject to the City Council's approval of bond documents. SUMMARY: Award of this contract will construct a new parking lot at the northeast corner of Amado Road and Calle Alvarado, as well as adjacent street improvements, in conjunction with the expansion of the Palm Springs Convention Center. BACKGROUND: On May 7, 2003, the City Council approved the Convention Center Expansion project, which included construction of a new parking lot on vacant City land located at the northeast corner of Amado Road and Calle Alvarado, and adjacent street improvements. Engineering Division staff was initially responsible for the preparation of the parking lot and street improvement plans, which was included in the original Bid Package solicited by Turner Construction in October and November. On November 19, 2003, the City Council rejected all of the construction bids and directed staff to re-design the convention center expansion plans such that the project costs would be lowered to an amount allowed by the project budget. Additionally, Engineering Division staff was directed to proceed with preparation of a separate Bid Package for the parking lot and street improvements, including landscaping and irrigation for the parking lot. The landscaping and irrigation plans were prepared by Michael Buccino. Therefore, Engineering Division staff assembled project specifications and a Bid Package for this project, consisting of several Bid Schedules to give City Council options for awarding components of the project in the event construction bids are higher than the budget allocated for the parking lot and street improvement construction. The Bid Package includes eight Bid Schedules. Bid Schedule A includes a scope of work that is all inclusive and will construct the entire "North Parking Lot", and adjacent street improvements, as well as associated parking lot landscaping, irrigation, and parking lot lighting and electrical system. Alternative Bid Schedule A includes a scope of work that will construct only the south half of the "North Parking Lot", and adjacent street improvements. Companions to these two Bid Schedules are options related to the decorative meandering sidewalk, and the size of the "Southern Live Oak" trees to be installed. 4y)q Palm Springs Convention Center Expansion Parking Lot&Street Improvements March 24,2004 Page 2 Another separate component to the project is the requirement to install storm drain improvements at the northwest corner of Amado Road and Avenida Caballeros. A standard requirement associated with construction of parking lots is to accommodate the increased storm water runoff resulting from the conversion of vacant land to an impervious paved surface. The increase in runoff is somewhat substantial, and measures are necessary to collect this runoff so that downstream properties are not affected. Most areas of the City do not have storm drain facilities with which to use to direct this increased runoff, however, in this case, the City has a large storm drain facility within Avenida Caballeros maintained by Riverside County Flood Control District into which the increased runoff may be directed. Additive Bid Schedule D includes the scope of work to install a catch basin, storm drain lateral and related improvements to facilitate this issue. This scope of work is necessary without regard to what portion of the parking lot is awarded by Council, and was a mitigation measure associated with the approval of the Convention Center project. The last component of the project is the proposal to construct a decorative meandering colored concrete pedestrian walkway across the east leg of Amado Road. This improvement would provide for a clearly delineated crossing point, with curb "pop-outs" on the northeast and southeast corners of the intersection to allow for a narrowed and safer pedestrian crossing point from the parking lot to the Convention Center. Additive Bid Schedule E includes the scope of work to remove existing improvements at the Amado Road and Calle Alvarado intersection and to construct the decorative pedestrian walkway. The project was advertised for bids, and at 4:00 P.M. on March 12, 2004, the Department of Procurement and Contracting received bids from the following contractors (see Attachment 1 for bid results): Contractor: 1. Contreras Construction Co.; Indio, CA 2. Vance Corporation; Rialto, CA 3. Granite Construction Company; Watsonville, CA 4. Matich Corporation; San Bernardino, CA The Engineer's Estimate was $962,000 for Bid Schedule A; $628,000 for Alternative Bid Schedule A; $28,000 for Additive Bid Schedule D; and $60,000 for Additive Bid Schedule E. Estimates for the Deductive Bid Schedules were unknown. The basis of award is the total sum of Bid Schedule A, Additive Bid Schedule D, and Additive Bid Schedule E. The low bidder is Contreras Construction Co., from Indio, CA. The company is a California partnership whose partners are Enrique Contreras and Ruben Contreras. Funds for this project are available from a number of sources. Of the total contract amount of $730,356.25, $148,215.90 represents the total cost of associated street improvements for Amado Road and Calle Alvarado, as well as the entire cost of Additive Bid Schedule E ($52,045.00) for the decorative pedestrian cross-walk and related street improvements that will be funded through local Measure A revenue funds budgeted in account number 134-4498-50227 (Amado/Alvarado St Improv). Funding for the storm drain improvements for this project, Additive Bid Schedule D, ($28,962.50) will be funded from unallocated drainage fund revenues budgeted in account number 135-4371-50227 (Tachevah Outlet Drain Connector). q#2,-- Palm Springs Convention Center Expansion Parking Lot&Street Improvements March 24, 2004 Page 3 The balance of the total contract amount, $553,177.85, includes the cost of constructing the south-half of the "North Parking Lot", including all associated parking lot improvements, landscaping, irrigation, lighting and electrical system improvements (Alternative Bid Schedule A) and is scheduled to be funded from future revenue generated by the Convention Center Expansion Bond issue. The award of this contract is subject to City Council's approval of those bond documents. SUBMITTED: I DAVID J.
