Pretium was involved in a complete building renovation for the existing office and patient care area at this location.
The building upgrades required the relocation of existing mechanical services, and the addition of a sprinkler system, where no system was previously installed.
Pretium coordinated with the architect, contractor and the City, to provide separate incoming domestic water and fire suppression service lines in separate rooms, to optimize useable space in the existing building.
Additionally, existing gas-fired HVAC equipment was removed and replaced with variable refrigerant flow (VRF) heat pump systems which allowed for precise temperature control in multiple office and treatment spaces.
To deliver this project, Pretium completed the following measures:
Mechanical Design
Our mechanical engineering team delivers technically sound, practical, energy, and cost-saving solutions while ensuring our clients’ satisfaction. Our team of highly skilled professionals can provide solutions for any retrofit or new construction project
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
Pretium worked with the design team to provide optimal HVAC system design for maximum flexibility, energy efficiency, and greenhouse gas reduction.
From the initial project planning stages, our team was involved with coordinating space planning and site service requirements during the renovations.
This allowed for smooth project progression with coordination between multiple parties, ensuring the safety of building occupants through the installation of fire suppression systems.

Pretium was engaged to provide an assessment and design for the replacement of existing incoming domestic water piping.
Other deficiencies were noted on-site during our review and building domestic water systems were upgraded to meet current municipal and code requirements. Pretium provided coordination and provision of new incoming domestic water for fire suppression and domestic water use, including a new incoming water room.
Backflow prevention was installed to meet cross-connection survey results, and incoming water services were relocated to avoid the use of a failing buried incoming line installed below the building.
To deliver this project, Pretium completed the following measures:
Condition Assessment
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.
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
Pretium was able to work with the project team to complete the work while the building was fully occupied. This included assisting with managing occupant expectations and working with the contractor to schedule and phase the work to minimize impact.
During construction, it was discovered that an existing incoming domestic water line serving the building had been relocated and abandoned without any public record. There was a planned eight-hour water shutdown for final connections to be made, and this issue was discovered once the final connection was made.
Pretium worked immediately with the contractor and client to provide temporary water service and ultimately locate and connect to the unmarked piping. Pretium was in constant communication with the contractor and property manager during the unplanned additional work to maintain coordination and ensure the property was aware of challenges and solutions on site.

Pretium was responsible for the complete design, prime consulting, construction review, and construction administration services for hydronic system upgrades at three university buildings.
New piping upgrades were completed, extending through three buildings to complete an ongoing phased central boiler plant expansion project. Hydronic systems were installed and updated to allow for connection into a recently installed central condensing boiler plant. Building upgrades included the removal of individual boiler systems and gas–fired, domestic hot water heaters for replacement with heat exchangers and piping tied into the central boiler plant in one of the three buildings.
Pretium’s involvement began with an application and award to a public tender for this hydronic system upgrade. The RFP included a general concept for the application of a second phase of construction for heating plant consolidation. Pretium performed extensive site reviews and documentation for pipe routing through existing operating buildings.
Pretium acted as the prime consultant on the project and coordinated in-house structural engineering review for new and updated equipment. We worked with an external electrical engineering firm to coordinate the electrical requirements for new and removed mechanical systems. A complete and coordinated set of bid documents were presented to Laurier University’s procurement group for public tendering through the school’s formal channels. We aided in contractor site reviews and the tendering process.
Upon award of construction, Pretium coordinated and organized a pre-construction meeting, outlining the roles and responsibilities of all parties. Ongoing site reviews and coordination took place during project construction. During the final balancing of the system, it was noted that design flows were not achieved at remote building locations. Pretium took the lead and chaired a meeting between the university stakeholders and the Phase One design engineers to coordinate changes to the base building systems. The proposed changes were accepted by base building engineers and the revisions were implemented.
To deliver this project, Pretium completed the following measures:
Mechanical Design
Our mechanical engineering team delivers technically sound, practical, energy, and cost-saving solutions while ensuring our clients’ satisfaction. Our team of highly skilled professionals can provide solutions for any retrofit or new construction project
Electrical Design
Working alongside our Partners and Mechanical Engineering team, serving as the prime consultant, our team offers electrical design services. This allows clients to have a one-stop shop for all of their mechanical and electrical needs.
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
Due to the updated design, the connected gas load was reduced and each building is now positioned to transition to lower heating water temperatures, allowing for future connections to a proposed central geothermal heating system.
Project construction took place on an active university campus at the height of the COVID-19 pandemic. Project staffing, access, protection, and building protocols were changing constantly. Pretium worked closely with the University project managers to manage project timelines and adjust schedules to meet continually updating building access requirements, including complete lockdowns.
Following project completion, Pretium corresponded with the University periodically to answer questions regarding system operation and to help fine tune individual system components as the building operated in each of its first four seasons.
