CES Group was commissioned by the Greater Toronto Airports Authority (GTAA) as the Prime Consultant for design and implementation of the backflow prevention upgrade and renewal project across multiple facilities within GTAA portfolio buildings.

Within the twenty-eight GTAA facilities, there was approximately five hundred BFP’s that needs to be added and/or retrofitted to ensure compliance to the Region of Peel’s by-law 10- 2017.

As part of our consulting services every cross-connection point included in the above referenced CCS was addressed and made complaint to Region of Peel Backflow Prevention Bylaw No 10-2017 and CSA standard B64.10-17.

Specific attention was given to accessibility to each BFP device for facilitating future testing and functional verifications. Any BFP device located above 1.2 meter from the slab was reconfigured and dropped to levels at 1.2 meters to allow device testing without need of ladders or higher levels access support equipment. Two backflow preventors in parallel arrangements were specified for all locations related to water incoming stations (premise isolation) to allow for uninterrupted water services during regular testing and maintenance procedures.

The project scope included definition of contactors work for the following Divisions: a) Division 3 –Structural work for Bollards for mechanical system protection in relation to airside terminal work; b) Division 21 – Piping Retrofit and installation of Backflow Preventors within Sprinkler Line Incoming Station; c) Division 23 – Piping Retrofit and installation of
Backflow Preventors; d) Division 26 – Heat Trace system reconfiguration for facilitation of mechanical work; e) Division 28 – Fire alarm system modification to accommodate for addition of supervisory valves across sprinkler line backflow preventors.
