PURPOSE
The purpose of this report is to obtain Council approval to award Contract No. 9921, for the construction of a PRV station at 1st Avenue and Rupert Street, to the low bidder - Ponte Bros. Contracting Ltd.
BACKGROUND
The Waterworks 1997 - 1999 Capital Plan, approved by Council, includes funding for the PRV replacement program. This program was initiated to replace those PRV stations throughout the city that are past the end of their service life. To date, 16 of the Citys 29 PRV stations, approximately 55%, have been replaced or significantly updated.
The planned replacement of the PRV station at 1st Avenue and Rupert Street will complete the Citys current requirements under the PRV replacement program. This PRV chamber is past its service life: all piping within the chamber needs to be replaced, the pressure regulating valves have a high maintenance history (the emergency 10" pressure reducing valve within the chamber has been out of commission for approximately three years), and there is inadequate access and headroom, as well as insufficient lighting and heating, for staff to perform their maintenance duties. The proper operation of this PRV station is essential to provide a reliable supply of water for both domestic consumption and fire protection within the Citys 490 Pressure Zone.
DISCUSSION
A detailed design and tender documents were prepared by Omni Engineering Inc. (the Consultant) for the new PRV chamber noted above. The work will be administered under a lump sum/unit price construction services contract. Lump sums for each tender item and unit prices are used to calculate interim progress payments to the contractor.
Eleven contract bidders submitted complete tender packages, including bonding requirements. A summary of the bids received follows:

11. BGM Construction Ltd. $541,730.30~ After correction of minor addition errors in bidders total.
The low bidder, Ponte Bros. Contracting Ltd., appears qualified to construct the new PRV chamber based on their satisfactory completion of other waterworks projects. This contractor is currently working for the City of Vancouver for the replacement of distribution watermains past their service life (Contract No. 9906). To date, their performance has been very good with respect to both their quality of work and their dealings with members of the public. Therefore, staff recommend that Ponte Bros. Contracting Ltd. be awarded Contract No. 9921 for the construction of the new PRV chamber noted above.
FUNDING AND COST
The low bid for Contract No. 9921 is within the Consultants preliminary contract estimate of $386,163.00. The total cost estimate for the work, which includes the contract price, 10% overhead, and cost of related City work, is $425,000. The final cost of the contract will vary from the bid price because the estimated quantities of work for unit price items may be different than the actual quantities of work. Funds for this project are available from the PRV Stations Replacement Program (order group C07E1C).
