Assessment and Capital Planning New Construction

Summary

Pretium Engineering successfully completed a full window wall replacement at the Rosedale Glen Condos while keeping residents in their homes and staying under budget. This article outlines the thoughtful planning, detailed assessments, and clear communication strategies that made it all possible.

There’s no easy way around it – carrying out window wall and other fenestration replacements at a multifamily building is a necessity that can be onerous on property managers, condo boards and residents. It is possible to minimize disturbances and expenditures, but it takes thoughtful preparation, careful planning and ongoing communication with all parties.

That’s how Pretium Engineering managed our replacement program at the Rosedale Glen Condos, a 44-year-old development near Mt. Pleasant Road and Rosedale Valley Road in Toronto, Ontario.

Here are the details on how we kept residents in place and came in under budget while conducting a complete replacement program throughout the building’s two towers

We began by investigating the structure’s condition to identify what elements needed to be entirely replaced and where we might be able to save the client money.

1. Understanding the assignment

It’s integral to have a solid understanding of the assignment before jumping into action. This includes doing a building condition audit to look for wear and tear on existing infrastructure and determine its operational status; estimating project costs and conducting a reserve fund study; and building out timelines.
We began by investigating the structure’s condition to identify what elements needed to be entirely replaced and where we might be able to save the client money.

We reviewed the condos’ 180 suites, examining the state of sliding doors and window walls.
We identified the existing insulation system and how it interacted with the original glazing system, made from aluminum-framed window walls with a combination of fixed insulated glazing units and single pane horizontal sliders.

Once this thorough investigation was complete, we determined that we would need to remove and dispose of all existing windows, doors, spandrels, interior drywall at the jambs, ceiling finishes at the head, flooring at sills, and accessories.

Armed with information, we designed a renovation program to install new aluminum-framed systems at all windows, doors and spandrels, along with new metal transitions from the existing structure to new systems, sealants, and interior finishes. For the exteriors, we decided that some areas needed complete masonry and insulation replacement, but not all.

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.

Project Value
$400,000,000
Project size
2 buildings (190,000 sq ft and 280,000 sq ft)

This project included the construction of two Metro Distribution Centres, one sized at 190,000 ft2 for frozen food distribution and one sized at 280,000 ft2 for fresh food distribution.

The centres were constructed between 2019 and 2021. Pretium completed a full-time third-party site review of: 

  • roofing 
  • insulated metal panel cladding 
  • spray foam insulation 
  • curtain walls 
  • masonry construction at both facilities 

Water penetration and condensation investigations were also performed in the post-construction phase using: 

  • water testing standards and techniques 
  • infrared thermography 
  • moisture scanning 
  • temperature/humidity monitoring equipment  

To deliver this project, Pretium completed the following measures:

Third Party Review

Third Party Review

From specialist review at the design stage to assisting with quality assurance on behalf of the design authority or general contractor during construction, we provide the necessary engineering services to ensure work is performed to the highest standard. By leveraging our extensive experience in restoration projects, we can help teams to avoid common pitfalls.
Water Leakage Testing

Water Leakage Testing

Both qualitative and quantitative water leakage testing of building envelope components are provided including, but not limited to, in-situ performance testing of windows and doors and the use of water spray and blower doors to simulate the effects of a wind-driven rain.
Infrared Thermography

Infrared 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.

Client Benefits 

Pretium worked within a large project team including the owner, architect, general contractor, and multiple subcontractors to ensure construction was executed to the highest standards and level of detail. 

Refrigeration and freezer buildings require extreme air tightness and thermal detailing to prevent interior condensation and moisture related issues. Pretium completed regular site reviews to resolve deficiencies as they came up post-construction to minimize issues once the buildings were in use. For condensation and moisture issues that were identified, various testing techniques and equipment were utilized to resolve them. 

This project was in active construction during the height of the COVID-19 pandemic. Pretium staff worked diligently with the General Contractor to follow all on-site health and safety requirements.
