Item - 2023.GG8.4

The General Government Committee:

1. In accordance with Section 71-11.1.C of the City of Toronto Municipal Code Chapter 71 (Financial Control By-Law), authorized the General Manager, Toronto Water to amend Purchase Order Number 6041895 with CH2M Hill Canada Limited, for construction administration services for the rehabilitation and upgrades of HVAC at R.C. Harris and Island water treatment plants, to increase the overall value by $314,573 net of all applicable taxes and charges ($320,110 net of Harmonized Sales Tax recoveries).

2. In accordance with Section 71-11.1.C of the City of Toronto Municipal Code Chapter 71 (Financial Control By-Law), authorized the General Manager, Toronto Water to amend Purchase Order Number 6050318 with Alberici Constructors Ltd. for construction services for the rehabilitation and upgrade of HVAC at R.C. Harris and Island water treatment plants, to increase the overall value by $1,300,000 net of all applicable taxes and charges ($1,322,880 net of Harmonized Sales Tax recoveries).

The purpose of this report is to request authority from the General Government Committee to amend purchase orders related to the HVAC rehabilitation and upgrades being carried out at the R.C. Harris and Island Water Treatment Plants (WTP).

These amendments are required for additional construction administration services to accommodate the revised construction schedules submitted by the general contractor.

Since the start of construction, the schedule was extended several times due to change orders issued to address added scope related to unforeseen site conditions and associated design changes. The schedule was further impacted by constraints caused by COVID-19 and longer equipment delivery timelines due to the global supply chain disruption.

Additional scope was required to address unforeseen site conditions (e.g., structural modifications to site facilities, natural gas piping, and asbestos testing and abatement) and additional efforts to solve issues related to heritage site requirements at the R.C. Harris.

The amendments requested total $1,642,990 (net of Harmonized Sales Tax recoveries) and would increase the current value of two (2) purchase orders.
