Purchase Order Amendment for General Contracting Services Number 6056841 with Pomerleau Inc., for General Contracting Services for Toronto Paramedic Services Multi-Function Station at 300 Progress Avenue

As part of efforts to accommodate increases in Toronto Paramedic Services' emergency call demand and staff resources, the City of Toronto is constructing a Multi-Function Station located at 300 Progress Avenue. The new station will be part of the Toronto Paramedic Services' active deployment model to achieve greater efficiencies in the preparation of equipment and vehicles, and to allow more targeted deployment of paramedic crews across the city to respond to emergency calls. Following execution of the agreement with the general contractor, Pomerleau Inc., in February 2025, the contractor mobilized on site in August 2025 and at that time, the targeted project completion date was determined to be by April 30, 2028. This purchase order amendment is required to address unforeseen site conditions and increased design coordination, which has significantly impacted the construction schedule. Accordingly, the requested amendment includes an extension of the contract end date from April 30, 2028 to September 30, 2029, to align with the revised project schedule. This purchase order amendment is required to address: 1. Concealed and Unforeseen Site Conditions - $11,900,000 Costs related to addressing the extensive concealed and previously unknown site conditions that could not have been reasonably identified and avoided through pre‑construction investigations. These investigations, included extensive geotechnical assessments led by an external subject matter expert, comprising of almost 200 borehole investigation points (to depths of approximately six to ten metres), groundwater monitoring, and environmental sampling conducted by qualified consultants, primarily within the proposed building footprint. These assessments were carried out in accordance with industry best practices and indicated generally manageable subsurface conditions, with only localized contamination. Despite the results of the investigations, excavation on the site revealed buried foundations and structural remnants from previous site developments as well as contaminated and salt‑impacted soils requiring expanded testing, segregation, specialized handling, off-site disposal, and inspection. During the removal of the buried foundations, unanticipated water removal associated with prolonged excavations and wet ground conditions arising from these discoveries were required. Remediation of the unforeseen site conditions include excavation, haulage, transport and disposal fees. The additional work required to address the unforeseen site conditions is near completion; the site has been successfully dewatered, with excavated areas now dry and undergoing compaction in preparation for subsequent construction activities. The requested purchase order amendment amount is to replenish project budget expended to address the extensive unforeseen site conditions. It is important to note that even if these site conditions had been identified during the initial investigation phase, the additional costs associated with removing the buried foundation and contaminated soil would still have been incurred. 2. Contingency Allowance - $7,670,687 Due to financial constraints at the time of the general contractor award, the purchase order was issued with minimal contingency allowance for a project of this complexity. As a result, the original contingency allowance was insufficient to absorb the unforeseen site conditions. An additional contingency has therefore been established as an owner's contingency, which is a contingency to be utilized at the discretion of the City only if required to address further unforeseen conditions or changes that are not currently identified. In line with industry best practice, this contingency represents an upset limit equivalent to 20 per cent of the overall project budget. 3. Additional Design Coordination - $3,000,000 During the early construction coordination phase, several deficiencies attributable to consultant design errors and omissions were identified. These have resulted in additional construction costs that must be addressed to allow the project to proceed. The additional costs are tracked for potential subsequent cost recovery. The total value of the purchase order amendment being requested is $22,570,687 net of all applicable taxes and charges ($22,967,931 net of Harmonized Sales Tax recoveries) revising the current purchase order value from $96,152,712 net of all applicable taxes and charges ($97,845,000 net of Harmonized Sales Tax recoveries) to $118,723,399 net of all applicable taxes and charges ($120,812,931 net of Harmonized Sales Tax recoveries).
