ensure all related equipment and services stay powered up and in proper working order. Ensure
other ongoing activities, in close proximity or otherwise, do not disturb or interrupt the operation of
the existing systems or the work already commissioned or placed into operation. Should any such
activity pose a risk to this work, or to the system operation, advise the Engineer and the City
immediately.
.3
In general, the work involves the supply installation, modification and commissioning of the
necessary hardware for the SCADA system upgrades to the City of Guelph Lift Stations as
indicated on the drawings. Automatic control will be performed by a new Allen Bradley PLC based
system and will report to the Plant SCADA. Existing auto dialer alarming systems will be

.2
All functionality described in the Documents shall be fully implemented.
.3
Demonstrate operational system and put all equipment into operational service to the satisfaction of
the Engineer. Satisfactory performance of the system shall be assessed on the basis of the entire
control system being fully operational and in use under peak load conditions during the process
run.
.4
All performance requirements shall be based upon worst case scenarios.
.5
Provide documentation in timely manner and as specified.
.6
At all times, ensure that work being carried out by the Engineer or the Owner’s operations staff are
properly coordinated with all ongoing construction activities and are unhampered by unnecessary
delays or obstructions. Costs incurred by the Engineer or Owner resulting from undue
impediments, whether caused by lack of coordination, non-compliance with the specification, or
poor cooperation among trades, can be billed directly to you, or alternatively, claimed against the
maintenance holdback.
