255 Riverside Drive East is a 20-story, 300-unit non-profit housing building originally constructed circa 1975.

As one of the largest social housing providers in Ontario, Windsor Essex Community Housing Corporation (CHC) has a deep commitment to sustainability, implementing projects at their existing buildings that are targeting the highest performance levels and creating new high performing buildings. With that in mind, Pretium was selected to be the Prime Consultant to complete CHC’s first Step-Wise EnerPHit project at Riverside Drive.

The project team conducted a feasibility study to determine options for each of the systems requiring renovation. Eighteen scenarios were modeled in PHPP with changes to the:

Exterior cladding
Balconies
Roof assembly
Floor slab and foundation walls
Ventilation design
Domestic hot water system
Vent stacks
Penthouse
Lighting

The design options were narrowed down based on the EnerPHit requirements, impact on residents, and price until an optimal recommendation was achieved. Energy modeling and reporting for the National Housing
Co-Investment Fund was also completed.

Specifications for the renovation were prepared including the preparation of detailed drawings, permit application, and architectural renderings for the new exterior cladding. Construction review and contract administration services
are ongoing with mechanical system installation complete and building envelope upgrades scheduled to be complete in July 2024.

To deliver this project, Pretium completed the following measures:

Condition Assessment and/or 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.

Energy Modelling

A quantitative tool that assists designers in evaluating the environmental, technical, and financial viability of a proposed building retrofit or design for a new building. The data obtained from the analysis allows designers to communicate recommendations to building owners and managers more effectively. The information is used to identify optimal solutions.

Design and Specification

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.

The building has been given new life, with all upgraded systems and an eye-catching black, white, and blue exterior. The benefits of this project do not stop at the extended life and curb appeal:

The annual energy consumption is expected to drop approximately

65%

The thermal bridge free design and new continuous fresh air ventilation system combine to significantly improve indoor air quality and occupant comfort.

The annual greenhouse gas emissions are expected to drop approximately

Project size

1 building (740,000 sq ft)

The commercial retail building had 91 roof sections, totaling approximately 741,000 ft²,and was constructed in three major phases from 1973 to 1986 with smaller additions made from 1993 to 2019.

The project began with a roof condition assessment in 2022. Thermography identified several anomalies, and subsequent test cuts confirmed moisture trapped in several assemblies. Test cuts also revealed that most of the roof sections were renewed by installing a new assembly over the original assembly, and in some cases a third assembly was installed, raising concerns about structural loading. Pretium calculated the approximate dry/wet weight of each roof section for the client and their structural engineer’s review.

Working within the client’s budget to replace as much roofing as possible, Pretium prioritized four roof sections (32,300 ft²) that were replaced in 2023. Pretium’s involvement included providing design, technical specifications and drawings, tendering, project management, and construction review for this phase of the project.

Further assessment was then carried out in 2023 with repeated thermography and additional test cuts, further confirming moisture in some assemblies and multiple assemblies having been installed on most of the sections. A strategic roof replacement plan was finalized including budget estimates for capital replacement and operations (maintenance and emergency repairs). The plan was divided into phases spanning 15 years. Annual assessments were planned to prioritize annual work based on current conditions.

Pretium then provided design, specifications and drawings for tender of the replacement of 12 roof sections totaling over 100,000 ft² beginning in 2024.

To deliver this project, Pretium completed the following measures:

Thermography

Condition Assessment

Roof Openings / Test Cuts

Our team creates small openings to determine roof compositions including the type of membrane, type and thickness of thermal and tapered insulation, and overall roof assembly height, type of vapour barrier, and the condition of the roof deck. Openings also allow us to confirm the presence of moisture in the roof.

Design and Specifications

Tendering

Contract Administration and Construction Review

Client Benefits

Pretium helped identify potential structural overloading at many roof sections which prompted the client to initiate a revised structural analysis of all roof sections.

We also helped to educate the client regarding best roofing practice regarding the installation of new materials over existing. Pretium identified the replacement value of the roofing based on local market conditions, which helped the client to secure a significant budget plan for the next 15 years. The greatest challenge was prioritizing roof replacement based on so many factors, all of which that are not typically experienced on a single property including:

budget
age and condition of multiple assemblies on the majority of roof sections
moisture content
structural concerns on a significant number of roof sections

This challenge involved many meetings and conversations with the client and internally. Working with the client to secure an immediate, significant budget for critical replacement was a challenge, considering the extent of required roof replacement in the short term.

Being a property situated in Quebec, all technical documents are required to be produced in French for distribution to contractors. Significant time and effort were required to overcome this challenge.

Due to the physical size of this property and the fact that many of the roof sections required attention in the short term, physically assessing the roofs, performing two thermographic scans and test cuts on over 80% of the roof sections, and organizing the information into a single report was also a challenge that was overcome by significant team effort.

Ultimately, the client has been very satisfied with the result and has praised Pretium for our diligence and expertise.

Canlan Ice Sports – York is a is a state-of-the-art multi-purpose recreation and entertainment facility featuring five NHL and one Olympic-sized playing surfaces.

Covering the rinks and the restaurant are six roof sections constructed from a pre-engineered metal roofing system with fiberglass insulated blanket and an integral vapor barrier. The existing standing seam metal roofs were showing signs of stress due to leaks; causing corrosion of the purlins and interior damage.

The selected PVC membrane roof reconstruction design moved the insulation (and dew point) above the metal panels. This eliminated the formation of any trapped moisture and the insulation below the roof deck. By removing the interior insulation this allowed the purlins to be repaired, cleaned and painted.

To deliver this project, Pretium completed the following measures:

Condition Assessment and/or Feasibility Study

Design and Specification

Design documents with comprehensive specifications and detailed drawings are prepared to describe the project scope, materials, and procedures. These documents are created based on information collected during the assessment and feasibility phase and with the Owner’s agreement on the restoration and renewal approach and budget. Design and specification documents not only communicate the scope of work to the contractor but do so in a way that promotes refined pricing. An effective, collaborative planning and design process increases the potential for success during construction through improved workmanship, fewer changes and disruptions to building occupants, a shorter construction schedule, and a final cost within budget.

Tendering

A fair and competitive tender process is followed. We offer tenders to pre-qualified contractors who have known skills for the required work. 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.
