Project size

1 building (110,000 sq ft)

The facility at 111 Scotia Court is Factory Mutual (FM) insured and has a total of approx. 110,000ft² of conventional roofing over a distribution center.

The project included the replacement of the existing BUR roof assembly throughout with a new TPO roof assembly, roof drainage upgrade, and asbestos abatement.

Pretium was engaged in the spring of 2021 to aid in roof rehabilitation efforts at the facility. Over the subsequent two to three months, Pretium conducted reviews of the various affected systems, providing services such as:

Thermography (IR Scan)
Roof Assembly Review
Roof Structure Review
Roof Drainage Review
A roofing-specific DSS (Designated Substance Survey) carried out by our sister company, Peritus Environmental.

Throughout the summer of 2021, Pretium developed specifications and drawings for a full roof replacement to FM requirements, roof drainage system upgrades, and asbestos abatement, prepared by Peritus. The project was tendered in the autumn of 2021, with Pretium’s assistance in contract preparation. Construction review and contract administration were provided by Pretium until the project’s completion in early 2023.

To deliver this project, Pretium completed the following measures:

Thermography

Infrared thermography is used in building science to detect thermal variations in building envelope assemblies using non-destructive infrared (IR) radiation detector sensing equipment. Detection of these thermal variations can be used to identify a variety of potential deficiencies.

Condition Assessment / Feasibility Study

A detailed assessment of existing conditions, including drawings, permitted use, failure mechanisms, and remedial options, allows for clients to choose the building restoration and renewal program that best suits their objectives.

Structural Review

Our structural team provides the design of unique and innovative foundations and other building structures in provinces across Canada. Our designs are often substituted for more common engineered solutions that are impractical or too expensive. We develop structural solutions where other solutions fail to meet a client’s needs

Roof Drainage Review

Our team will conduct a thorough review of your roof’s drainage systems, identifying potential issues and recommending solutions to be incorporated into your roof renewal program. Proper roof drainage is crucial for preventing damage and maintaining the integrity of your roof and building.

Designated Substances Survey

Working with our sister companies through the C3 Group, our team can offer either project-specific or whole-building designated substance surveys (DSS) to our clients.

Design and Specifications

Design documents describe the project scope, materials, and procedures based on information collected during the assessment/feasibility phase with the Owner’s agreement on approach and budget. They communicate to the contractor in a way that promotes refined pricing and increases the potential for success through improved workmanship, fewer changes and disruptions to occupants, a shorter schedule, and cost within budget.

Tendering

A fair and competitive tender process is followed for both public and private projects. During the tender process, we respond to queries, prepare addenda, and walk the work area with the bidders. On closing of tenders, we prepare a written summary and analysis of the bids received.

Contract Administration and Construction Review

Once a contractor is selected, our team periodically visits the site to confirm that the work is being completed in accordance with the project specifications and provides contract administration from start to completion.

Client Benefits

The roof replacement not only eliminated designated substances within the original roof assembly but corrected numerous water infiltration issues and improved rooftop drainage.

Pretium worked with the project team to complete the work while the building was fully occupied. This included working with the contractor to schedule and phase the work to minimize impact.
