2. Granted authority to the Interim Chief Engineer and Executive Director, Engineering and Construction Services to further negotiate the necessary amendment to the contracts with Green Infrastructure Partner Incorporated for additional scope of restoration on Heathrow and Calvington Drive, in accordance with the terms and conditions of the agreements and on terms, conditions and cost satisfactory to the Interim Chief Engineer and Executive Director, Engineering and Construction Services, and as a result to be able to amend the Purchase Order Number 6053935, as may be necessary from time to time, all in accordance with the condition of contract 19ECS-LU-01FP.

The purpose of this report is to request authority to amend Purchase Order Number 6053935 with Green Infrastructure Partner Incorporated (formerly known as Green For Life Infrastructure Group Incorporated) for enhanced road rehabilitation work on Heathrow Drive and Calvington Drive.

Construction of the Basement Flooding Protection Program Phase 4, which includes storm and sanitary sewer improvements, watermain replacements and road resurfacing on various streets in Wards 6 and 7, began in 2020, with an expected completion date of October 2023. As work progressed, it was brought to the City's attention that sections of Heathrow Drive (from 60 metres west of Chesham Drive to Jane Street) and Calvington Drive (from Dalsby Road to Lexfield Avenue) were in poor condition. This matter was investigated by staff and a further technical assessment was completed. Ultimately, it was determined that enhanced road rehabilitation, beyond the base scope of local road resurfacing, is required. The enhanced road rehabilitation will include replacing old asphalt layers with new asphalt layers and repairs of any damaged granular sub-base soft spots, as necessary, on sections of Heathrow Drive and Calvington Drive. Completing an enhanced road rehabilitation will extend the service life of the road and result in cost saving due to reduced maintenance.

Working with AECOM, who is the City's design and contract administration consultant on this project, a construction cost of $600,000 was estimated as the upset limit for the additional work. As such, a Purchase Order Amendment for an upset limit in the amount of $600,000, net of all taxes and charges ($610,560 net of Harmonized Sales Tax recoveries) is being requested, revising the current Purchase Order value from $24,832,823 net of all taxes and charges ($25,269,880 net of Harmonized Sales Tax recoveries) to $25,432,823 net of all taxes and charges ($25,880,440 net of Harmonized Sales Tax recoveries). This amendment is necessary in order to complete the additional scope of work.
