PWSGC mandated Equinox Construction Services (ECS) to carry out In-Services Support Services, including inspections, deficiency correction, start-up and shut-down procedures, and maintenance of the de-icing system within the Rideau Falls Dam complex. The Dam complex uses stoplogs to manually control the water level on the Rideau Canal and this location has a considerable ice build up during the winter months. The de-icing system is used to ensure the continuous operation of the dam and carries high-pressure steam in order for the operators to connect de-icing wands to connection points and free the stop logs.

The nature of the work provided by ECS consisted of managing the multi-year contract and various Task Authorizations (maintenance, upgrades and alterations), managing the specialty contractors, updating existing drawings of the de-icing system to include support locations and identifying points of interest for further NDT, annual inspection and maintenance of the de-icing system, ultrasonic thickness gauging to monitor points of interest for corrosion, and assistance with system start up and shut down during the period of operation.
