RQ16-261 Killiney Water Systems Upgrade (Underground Works) 1.0 PURPOSE
The Regional District of Central Okanagan (Regional District) has issued this Request for Qualifications (RFQual) in order to establish a list of proponents with the necessary expertise, availability and resources to perform the project outlined under the Scope of Work below. Only those proponents that pre-qualify will be eligible to submit a tender to the upcoming Invitation to Tender (ITT) process that is anticipated to follow this RFQual. This process is not intended as a pre-qualification of subcontractors or suppliers that may be retained by the proponent.
2.0 SCOPE OF WORK
The successful tenderer to the anticipated ITT will provide all construction services for the project as outlined below:
2.1 Context - Westshore & Killiney Beach Water Systems:
In 2016, the Regional District plans to complete projects to upgrade the water systems in both the Westshore Estates and Killiney Beach communities. Both communities are located on the west side of Okanagan Lake. Westshore Estates is located approximately 10km north of Fintry, BC and covers approximately 530 lots in the service area. Killiney Beach is located approximately 6km north of Fintry, BC and covers approximately 420 lots in the service area. For construction, the water system upgrades for both communities will be split into 2 contracts: Contract #1: Killiney Water Systems Upgrade (Underground Works) Contract #2: Killiney & Westshore – Pump Station and Reservoir Upgrades This RFQual is for Contract #1 only – the Killiney Water Systems Upgrade (Underground Works). A separate RFQual process is to be run for Contract #2.
RQ16-261 Killiney Water Systems Upgrade (Underground Works)

2.2.2 90% Drawings: Detailed Drawings at the 90% stage are attached to this RFQual as Exhibit A. These drawings provide a detailed overview of the Work. The drawings will be amended and added to by the time the anticipated Invitation to Tender is issued for the Work, but should provide proponents with a detailed overview of the intended works.
2.2.3 MMCD: The anticipated Invitation to Tender for the Work will be issued using the Master Municipal Construction Documents (MMCD) Platinum 2009 edition, together with Regional District supplementary conditions. The successful contractor will enter into an agreement with the Regional District for this Work based on this contract.

Section 01010 SUMMARY OF WORK
Page 1 of 4 Killiney Beach Water System Upgrades
Agua Consulting Inc.
1. GENERAL
.1 The Regional District of Central Okanagan (RDCO) owns and operates the Killiney Beach Water Utility. The utility provides water to approximately 279 single family residences above the northwest shores of Okanagan Lake. There is build out for this service area to a maximum of up to 429 serviced homes in total. The source of water for the utility is a water pipe and pumping system up from Okanagan Lake. To improve the reliability of the water system, reduce leakage and bring the system to current standards, the RDCO intends to upgrade the older Series type PVC pipe within the service area and renew service connections and appurtenances throughout the water system;
.2 The length of water main to be renewed consists of 728m of 100mm diameter main, 3,160m of 150mm main and 2,280m of 200mm main;
.3 The contract work includes the installation of new appurtenances such as blow-offs, air release valves, gate valves and water main fittings, and hydrant (where noted).
.4 The work also includes reconnection of the new water mains, new services and hydrants to the existing water system;
.5 Road surface restoration works are to be included in this contract. This includes road widths to half of pavement, full pavement and partial pavement where service crossings are required. Topsoil replacement and hydro-seeding is required in the off-road areas with ditch reconstruction required where drainage courses are to be reinstated;
.6 Two PRV stations are specified for construction. One is in the base contract and one is optional. An optional price is identified in the tender form;
.7 Creek crossing allowances must be made for Norris Creek. The creek is designated as a year-round water course and protection must be provided for water main installations when crossing the creek. The flow of water from within the creek must be routed across the water main installation to the satisfaction of the Qualified Environmental Professional;
.8 In conjunction with this work, there may be a concurrent reservoir and pump station contract awarded for upgrades to the Winchester Road Reservoir site. Coordination will be required with the adjacent contractor to facilitate access and work around that site.
1.1 Project Constraints
.1 There are several water course crossings shown on the plan and profile sections of the drawings. These water courses are to be maintained during construction as set out within the Environmental Assessment report included as Appendix B. The assessment of these water courses requires that their integrity not be compromised while crossing them with new water main installation;
.2 Road access must be maintained at all times. Roads must be passable for residents and for emergency response staff including Fire Department and ambulance. Roads fall under the jurisdiction of the Ministry of Highways who must be kept informed of the works and any changes in road access;
.3 The existing customers in the Killiney Beach water service area must continue to receive reliable water service during the construction period. Water main installation and service renewal installation should take place adjacent to the existing water system components with transfer of services to the new water mains once the new mains have been flushed, pressure tested and disinfected to acceptable standards;
Section 01010 SUMMARY OF WORK
Page 2 of 4 Killiney Beach Water System Upgrades
Agua Consulting Inc.
.4 The construction area is limited to the existing road Right-of-Ways. The ROWs are shown on the contract drawings. The paved roads within the service area are not centered within the ROW. Chainages are set to the centerline of the road right of way. Actual water main lengths are provided on the profile section of the plan-profile drawings;
.5 The staging of water main installation, flushing, pressure testing of main, and disinfection must be done in manageable segments. Maximum length of main that can be tested at one time must not exceed 365m length or lengths stated in the AWWA Disinfection Practices Manual, C651-14, Feb. 2015, unless first authorized by the Contract Administrator;
.6 Hydrant coverage and fire protection will be affected with the transition of fire hydrants from the old water mains to the new mains. The RDCO Water Operators and the Fire Department must be informed of any changes in fire hydrant service during the work. No more than two fire hydrants are to be permitted to be out of service at any one time during the project, and only with the permission of authorized persons within the Fire Department.
1.2 Schedule
.1 Begin the work at the earliest possible date respecting signing and administrative requirements
.2 Provide Contract Administrator and Owner with schedule for all major work tasks;
.3 Substantially complete the work within ___________________________________ of the date of award as per the Tender Form. Substantially complete requires all water main and facilities to be functional and on-line.
1.3 Work Sequence (General suggested approach)
.1 Construct the work in stages to minimize disruption of water service to the utility;
.2 Coordinate all work with the Contract Administrator;
.3 Retain Utility Locating Company to assist in main and service locates;
.4 Identify existing services and main alignments in areas where there is conflict with new main alignments. Advise Contract Administrator of recommended changes in Test Pit locations based on the information found;
.5 Excavate testpits and obtain locates on existing water mains. Provide elevation and location data to the Contract Administrator who will review the work with the Design Engineer;
.6 Perform site preparation works including clearing and grubbing, brushing of road ditches on pipe alignments;
.7 Locate suitable sites for stockpiling of excavated materials and for disposal of excess materials;
.8 Carry out water main installations maximizing impact to no more than 3 road sections at one time. Once a section of main is installed, flush, pressure test and disinfect the main and leave both mains (existing and new) in service so that service installations and transfers can occur with minimal impact on individual residence water service. Carry this out on an area basis, complete this and repeat procedure in the next area;
