1 Corporate Report Report from Transportation and Environmental Services, Engineering and Construction Date of Report: January 11, 2018 Date of Meeting: January 29, 2018 Report Number: TES File: Subject: P Bogart Street Park Splash Pad Award of Tender, Early Budget Approval Recommendation That Council direct staff to award the tender for P Bogart Street Park Splash Pad to Stolk Construction Limited in the amount of $433,010 plus HST; and That Council grant approval to use an additional $65,000 funded by the 2018 Capital Budget and that early Budget approval is obtained; and That the City Solicitor be directed to prepare the necessary by-law. FORTHWITH Background Bogart Street Park is a City Wide park in the North Planning District of St. Catharines. It is operated / permitted and maintained by the Parks, Recreation and Cultural Services. The park is made up of a two small 20 car parking lots, one soccer field, two tennis courts and creative play equipment. Installation of the splash pad and sun shelter in this location is intended for all the residents and visitors to the city. On March 21, 2016, Council received a report on the Outdoor Aquatic Facilities Strategy (Report PRCS ) and approved the following motion made by Councillor Phillips: That Council approve in principle the City of St. Catharines Outdoor Aquatic Facilities Strategy (Appendix 1) [contained in Report PRCS ]; and That Council direct staff to amend the 2013 Capital Budget for the purpose of re-allocating $1,110,000, previously designated for the renewal of facilities at Lancaster Park and Burgoyne Woods to implement the Outdoor Aquatic Facilities Strategy including: 1. Costs associated with the decommissioning and demolition of pools located at Lancaster Park, Arthur Street and Burgoyne Woods. 2. The construction of a splash pad to be located at the north end of the city; and Report Page 1 of 5

2 That a task force be established to determine the future Aquatic Strategy. FORTHWITH On June 6, 2017, the Task Force approved the following motion: That Port Weller Community Centre be the chosen site for the new outdoor splash pad. On October 16, 2017, Council approved the following motions: That Council approve the Port Weller Community Centre / Bogart Street Park as the preferred location for the North St. Catharines splash pad; and That Council direct staff to proceed to the procurement process of the design and build; and That staff be directed to include in the procurement process consideration for a cistern for reusing greywater for irrigation of current soccer fields; and That the amount not exceed $400,000 (Report PRCS ); and That the splash pad will be completed and opened by July 1, 2018; and Further, that Council refer the report to the Budget Standing Committee Meeting for their consideration of operating costs to open the splash pad in That the additional costs for a cistern for reusing greywater for irrigation of current soccer fields be included; and Further that staff review the Capital Budget to confirm this can be accommodated. On November 15, 2017, the Budget Standing Committee approved the following motion: That Council approve the Port Weller Community Centre / Bogart Street Park as the preferred location for the North St. Catharines splash pad; and That Council direct staff to proceed to the procurement process of the design and build; and That staff be directed to include in the procurement process consideration for a cistern for reusing greywater for irrigation of current soccer fields; and Further that the amount not exceed $400,000.

3 Report The project was tendered, and bids were received on Wednesday, January 10, Three tenders were submitted and opened, however, one was rejected at the first envelope due to missing information. The two remaining received tenders were checked. No errors were found. The tender prices are listed below. Tender Submitted by: Stolk Construction Limited Submitted (Incl. 1.76% HST) (Incl. 13% HST) $433, $440, $489, Ritestart Ltd. $488, $497, $552, Staff recommend awarding the tender to the lowest bidder, Stolk Construction Limited, at a cost of $433,010 plus HST. Retendering is not recommended and is unlikely to result in more favourable pricing or provide any improvements to the project schedule. Alternative prices were requested as part of the RFT to determine if any cost savings were achievable for a relaxed construction schedule. Both bidders indicated no cost savings for this relaxed schedule. Water Conservation Council had directed staff to include in the procurement process consideration for a cistern for reusing greywater for irrigation of current soccer fields. As part of the procurement process, alternative prices were also requested for a greywater capture system, which included a buried cistern, modifications to the sanitary drain and associated connections. These costs, which amounted to $34,100, were over and above the base-bid amount listed above. In order to utilize any water from the cistern, additional plumbing works (including a booster pump, pressure tank, backflow valves, piping, etc.) estimated at an additional $20,000 would also be required. Utilization of greywater for irrigation In discussion with staff from Planning and Building Services, the Ontario Building Code only allows for the utilization of storm sewage or greywater as a water supply for water closets, urinals, sub-surface irrigation, or the priming of traps. This restriction means that the spray irrigation system that exists in the soccer fields at Bogart Street Park would have to be replaced with a sub-surface (or drip) irrigation system. The installation of a drip irrigation system in a sports field would require the placement of irrigation pipes at mm (12-18 ) spacing versus the typical spacing of approximately 18 m (60 ) for the existing spray irrigation system. Staff have utilized drip irrigation systems in the past in landscaped areas, however, staff are not aware of any drip irrigation systems utilized in sports field applications. Staff s experience with drip irrigation systems in landscaped areas has been mixed, with increased maintenance costs being a concern. Detailed costs for replacing the irrigation Report Page 3 of 5

4 system at Bogart Street Park with a drip irrigation system are not known as staff (and the irrigation subcontractor the City typically uses) are not aware of any such installations. It is estimated that the costs would be in excess of $80,000. The existing spray irrigation system at Bogart Street Park is approximately five years old and is functioning well. Staff do not recommend replacing the irrigation system at this time. Existing irrigation costs Bogart Street Park The water consumption of the irrigation system at Bogart Street Park is metered, and the cost averages to approximately $3,624 per year at the current water / sewage rates. The peak consumption period was in 2012 at a cost of $6,650, while in 2017, there was no usage. These water consumption rates are considered typically low as soil conditions and drainage patterns differ from park to park. As a comparison, Guy Road Park soccer field averages an irrigation cost of approximately $7,489 per year. Utilization of greywater for other uses Other potential uses for the greywater from the splash pad may include filling of water trucks or utilization for flushing urinals or toilets in the Port Weller Community Centre. The City uses water tanker trucks for scheduled works which mostly involve watering plants, sod or other restored areas. In addition, staff will flush streets during spring cleaning and assist with clean up during construction. Staff typically fill up the water trucks either at our bulk water facility on Burbank Drive or the nearest fire hydrant to where they are working. While some of these activities could be anywhere in the City, most of the hanging basket plant watering occurs in the downtown, Port Dalhousie and Merritton areas. Requiring staff to fill their trucks at Bogart Street Park would result in inefficiencies in increased travel time that would far outweigh the financial benefits of utilizing the greywater from the splash pad. With respect to the washrooms at the Port Weller Community Centre, there are currently nine toilet / urinals in the building. The total cost associated with all water / sewage use at the Port Weller Community Centre has averaged approximately $641 per year for the last five years. As indicated above, the costs to install a greywater capture system, with associated plumbing, is approximately $54,100. In order to utilize this greywater for reuse in flushing urinals or toilets in the Port Weller Community Centre, additional costs would need to be incurred in installing a line from the cistern into the building and reconfiguring the plumbing and control systems within the building. Again, the costs associated with this work would far outweigh the financial benefits of utilizing the greywater from the splash pad. Utilization of greywater from the splash pad Given the fact that the existing spray irrigation system cannot be utilized and other uses for the captured greywater do not appear to be financially viable, staff do not recommend proceeding at this time with the implementation of a greywater capture system as part of Bogart Street Park splashpad.

5 It should be noted that the installation of a greywater capture system could be undertaken at a later date should conditions or code requirements change. The City has installed cisterns that capture rainwater runoff in other facilities, such as the Lake Street Service Centre (where the greywater is used to assist in washing vehicles) and the Kiwanis Aquatics Centre (where the greywater is utilized to flush urinals and toilets). Staff continue to investigate opportunities where the utilization of greywater systems would be financially and environmentally viable and beneficial. Financial Implications Staff have prepared an updated total project cost estimate of $465,000, including engineering design services, contract administration, testing, miscellaneous costs, and taxes. The total approved project budget is $400,000, resulting in a shortfall of $65,000. An additional $65,000 of funding is being proposed in the 2018 Capital Budget to cover the shortfall. Subsequently, staff are requesting early budget approval of these funds to proceed with the project in order to meet the City s proposed timelines for completion of July 1, Prepared by: Michael Otter, P.
