Cecelia Water Meter Replacement

CECELIA WATER METER REPLACEMENT

CONTRACT 2024-981



INVITATION TO TENDERSealed Tenders, plainly marked on the envelope "Tender for CECELIA WATER METER REPLACEMENT, CONTRACT 2024-981" will be received by Shari McCreesh, Purchaser, of the Capital Regional District at their office at 479 Island Highway, Victoria, British Columbia up to 2:00 pm local time on August 8, 2024, at which time they will be opened "in private". The works to be constructed under this Contract generally include, but is not limited to, the following:
The modification of an existing large diameter water main valve chamber to accommodate a 400mm (16”) magnetic flow meter installation with SCADA communication upgrades. This meter installation replaces an existing chambered ultra-sonic meter located in Cecelia Ravine Park in the City of Victoria. This project work will also include the decommissioning of two (2) existing meter chambers and a SCADA communication shed. Refer to tender package for the IFT Drawing Set, Specifications, and photos for details.
   KEY CONSTRUCTION DETAILS:

• There are two, close in proximity, work sites with different construction permit requirements. Refer to the Cecelia Meter Locations Details pdf included.
  1. The line valve chamber to be modified is located within the Cecelia Road roadway between Napier Lane and Jutland Rd. This area is known for commercial traffic.
  2. The existing meter chamber and a second meter chamber (abandoned) with a SCADA communication shed on top are located within the Cecelia Ravine Park which borders the Galloping Goose Trail.
      
• The 1067mm (42”) diameter steel water main, known as Supply Main No.1, is to be reduced to 400mm diameter prior to passing through the existing line valve chamber. Refer to IFT drawing pages C202 – C204 for modification details to this chamber.
  1. Valve chamber internal dimensions: 4m(l) x 3.4m(w) x 2.7m(h) with 250mm thick walls.
  2. Pipe modifications include the removal of all the existing pipework within the chamber as well as the cutting and reducing of the large steel water main outside the chamber. The exterior piping work will require excavation work in the roadway that extends approximately 5m beyond the east and west walls of this chamber. The new external pipework will include the addition of three direct bury gate valves with valve box access provided above within the road surface.
  3. The CRD wishes to keep the 42” butterfly valve actuator from the line valve chamber. All other pipework and equipment is to be removed from site and disposed.
  4. Structural modifications to the chamber are to the east and west walls where the steel main passes through the chamber. The overall internal dimensions of this chamber will not change with these modifications. Refer to IFT drawing pages C203 & C204.
     1. The concrete lid for this chamber is currently paved over and will need to be exposed. The design does not include replacement of the lid however the existing cutaway section will need to be exposed and removed to provide adequate chamber access for the new installations. Additionally, a hole for a new valve box will need to be cored through the lid. See IFT drawing page C203 & Photo titled: Cecelia Valve Chamber Site Details.
         
• Water Supply Main No.1 carries an impressed current as cathodic protection. Installation worksneed to ensure the cathodic protection is reinstated so the current is isolated from the meter and not grounded at the site. Refer to IFT drawing pages C203 & C301.
• The CRD preferred magnetic flow meter is the Endress & Hauser Promag W 400 c/w remote transmitter and a fully welded flow tube. SCADA monitoring and totalizer display is to be installed above ground in a kiosk located in the road right-of-way near the line valve chamber.
• A water sampling line will be incorporated into the new meter chamber and plumbed to a water sampling station located in the new kiosk.
• Supply Main No.1 has a flush\drain located in the Cecelia Ravine Park. This flush valve and all active CRD owned water infrastructure will be operated by CRD Staff ONLY.
• The CRD has certified isolating line valves on the supply main as single device isolating (SDI).
• Pressure testing of new pipe works may have to be performed at system working pressure as isolation is a challenge. A portion of the pressure test will be considered against new installed valves at 1.5x working pressure.

    DECOMMISSIONING & DEMOLITION WORKS:

  1. Existing Ultra-Sonic Meter Chamber - This chamber only contains the 1067mm steel water main with an ultra-sonic meter attached. There is no other electrical or mechanical equipment, valves, or other appurtenances in this chamber.
     1. Chamber internal dimensions: 2.75m(l) x 2.75m(w) x 2.0m(h)
     2. Demolition of this chamber includes removal of two (2) manhole hatches, disconnection of the meter, perforation of the chamber floor, backfilling, and surface restoration. Refer to IFT drawing pages C101 & C201 & Existing Meter Chamber photos.
  2. Existing Electronics Shed with Abandoned Meter Chamber - The electrical shed located in the Cecelia Ravine Park sits on top of a previously abandoned ultra-sonic meter chamber.
     1. The shed houses SCADA electronics, meter display and a water sampling station. There are no details regarding this shed in the IFT Drawings. Refer to the CRD record drawing pdf file titled Decommissioning Markups and the Shed & Abandoned Chamber Photos included in this tender package.
     2. The CRD has had a hazardous materials assessment completed on the shed and no asbestos containing materials were discovered and some lead paint was found. The complete report with disposal recommendations is attached, refer to Appendix F.
     3. The CRD will have the power source to this shed deactivated and will remove all electronic devices of interest prior to the Contractor demolishing the shed.
     4. There is one live 25mm water service line that runs from the shed and connects to the supply main. This copper water line is to be excavated at the main, disconnected, and capped. The active water main passes in front of the shed with only approximately 400mm of cover on the 1067mm (42”) steel main. Surface restoration for this exposure will include the replacement of paver stones.
     5. The shed has a manhole hatch to access the abandoned chamber below. This chamber is to have all water and electrical connections confirmed as disconnected. The chamber has no equipment required to be removed and is to be backfilled as per IFT drawing page C201 – Detail 1.
     6. Following the shed removal, the chamber lid is to remain in place. However, the tenderer is to provide provisional pricing for the lid removal and ground reinstatement with pavers.
     7. Abandoned chamber internal dimensions: 3.48m(l) x 1.83m(w) x 1.96m(h). 
  3.  Existing Line Valve Chamber Kiosk - Located near the line valve chamber (site of new meter) this kiosk is to be removed and replaced with a new kiosk as per the IFT Drawing Set. The CRD has no interest in any of the decommissioned materials from this kiosk.

• SCHEDULE
  In coordination, any construction works planned by the Contractor that require operation of any CRD infrastructure must allow for adequate advance notice to CRD Operational staff.
• The Contractor’s projected construction timelines are to indicate the overall water shut down period expected for the Supply Main No.1. This time frame includes CRD Operational involvement to drain the required section of water main (allow 1 day) and for the Contractor to perform all construction\demolition works.
• Construction is to be scheduled during the months of October – April to avoid the heavy water usage during summer months. Annual SCADA flow data confirms that the City of Victoria has adequate water supply via Supply Mains No.2 & No.3 to meet off season peak flow demands while Supply Main No.1 is out of service.
