  1. In conceptual or schematic phase, Precon manager and PX should use the WINT project estimate worksheet provided by WINT to establish a budget number for the project.  The KAST sales representative for WINT is Brent Harbour ( brent.harbour@wint.ai  (786) 755-1120, (512) 542-4652
  2. On receipt of DD or CD phase drawings, the PreCon manager with the assistance of the PX should engage WINT and send the drawings to Brent Harbour at WINT for proposed WINT monitoring design and pricing.  Please ensure you provide an expected due date for review with sufficient time prior to subsequent trade bid due dates.
    1. At DD Phase, the intent would be to recommend to the Owner & MEP Engineer to add the system as a design assist.  For either construction phase or operational use.
    2. Should mention to Owner the potential for savings on property insurance and potentially Builder’s Risk.  WINT can assist with this discussion with the Owner’s insurance broker, and they have contacts with several insurance carriers that can assist. Or they can review these case studies (Case Study 1, Case Study 2, Case Study 3)
    3. At CD Phase, we would add WINT during construction phase to Q&A and incorporate with drawing revision later.
  3. Schedule WINT Teams review with PreCon Manager and PX to finalize scope of services. At least 1 week prior to sub bid due date. PX should understand the system proposed by WINT and place valves where needed to protect the project.
    1. WINT will provide their suggested design to control areas and provide maximum amount visibility into where a potential leak is coming from.  Including but not limited to, temporary, fire, domestic, chiller lines, irrigation and water features.  NOTE, some projects have a boiler on the roof for hot water servicing the units, especially hi-rises.  In this case, we should investigate placing valves on that service going down to limit the head pressure, volume in the event of a failure.
    2. PX should provide insight into best most effective design for our needs.
      1. PX should provide monitoring duration to WINT for completion of the quote.  This should be once any water leak has the potential to damage the finished work.
      2. Note minimum monitoring points are 10 devices in the base software agreement with WINT; each additional valve is prorated. (Note there is a alternate program for 3 devices on selected projects)
      3. For high-rise best practice is to provide valves to limit head pressure from above.
        1. Minimum shall include Valve and Monitoring at any/all temporary water lines risers.  PX to provide estimated size of temporary.
        2. Minimum shall include Valve and Monitoring at the domestic water risers that make sense for the project.  Note all valves should be after the pump.  Recommend using the location of the designed riser isolation valves (typically manual valve) and replacing with an actuated valve with WINT monitoring.
        3. Fire Main shall be monitored only, due to liability issues.  The WINT device on the fire line will need to be removed at TCO per most AHJ requirements.
        4. There may be instances where a valve proposed by WINT is not required during Construction where there is no significant risk of damages to finishes, i.e. in a ground level retail shell space, and can be omitted by PX. 
      4. Once WINT monitoring is in place, a response protocol shall be established for return to site on indication of unexpected water flow. An alarm notification phone tree should be established starting with the closest KAST person to the project site and including the lead PM & Superintendent.  Secondary notification should be sent to PX, GS and RVP if no response within 15 minutes of time.
      5. With the assistance of the KAST Team, WINT should include add alternates in the GMP for:
        1. Post construction use of system by Owner of WINT devices installed during Construction.
        2. Unit level monitoring at submeter locations (requires additional actuated valves at unit main / submeter as applicable).
  4. Once the scope is agreed to WINT should provide:
    1. A final scope and drawing.  Exact placement of devices, should consider potential damage from the WORK or consideration should be given on protecting them.
    2. A quote for the material to be purchased and installed by the plumber and fire sprinkler subcontractor.  This is required for the transfer of the warranty.
    3. A quote for the monitoring carried by KAST this shall be coded to 15-371 (S)
    4. A quote for deductible insurance, Tier III, is carried by KAST this shall be coded to 15-371 (O)
    5. The PX should execute the WINT Work Order.  And Internal PO’s should be generated for the serves.
    6. Any discussed Owner Alternates.  To be contracted directly with the client, this would include Unit Level Protection
  5. PreCon with Assistance of PX should contact the apparent low bidder/bidders to explain the scope to be priced by the Plumber, Fire Sprinkler and Electrical Subcontractors.  Additional reference material can be used to explain how the system works (Guide).  The language below shall be incorporated into their scope.

 

  1. Plumbing / WATER MITIGATION – QA/QC

During the construction phase, the building will be equipped with an electronic water monitoring system (Wint), implemented to mitigate potential water damage during construction. Subcontractor shall furnish and install the necessary actuated shut-off valves Qty.10 (Wint compatible) required for the implementation of this system. At a minimum, the valves shall be installed at the temporary water line, ground floor domestic water line, main water risers, other specific locations (branches) shall be coordinated in the field.

  1. Fire Sprinkler / WATER MITIGATION – QA/QC

During the construction phase, the building will be equipped with an electronic water monitoring system (Wint), implemented to mitigate potential water damage during construction. Subcontractor shall furnish and install the necessary monitoring device (Wint compatible) required for the implementation of this system.

  1. Electrical / WATER MITIGATION – QA/QC

During the construction phase, the building will be equipped with an electronic water monitoring system (Wint), implemented to mitigate potential water damage during construction. Subcontractor shall provide power and wire the necessary actuated shut-off valves (Qty.10) required for the implementation of this system. The valves will be installed at the temporary water line, ground floor domestic water line, main water risers, other specific locations (branches) shall be coordinated in the field.

 

  1. Q&A Language as follows shall be incorporated into the Agreement  - Contractor is installing a mechanical water damage mitigation system for use during the course of construction, which will remain post-construction.
  2. Installation of the system should be coordinated with WINT and final inspection (TSO) Technical Sign Off, performed prior to start up.  Required for the insurance coverage.
