PROJECT HIGHLIGHTS | 2024-2025

PEACE VILLA HOUSES CLIMATE ADAPTATION To address a changing climate and increase climate resilience at Fort St. John Hospital’s Peace Villa Houses (residential care), active cooling was implemented to address the trend of increasing summer temperatures and to accommodate resident safety and comfort. To efficiently implement active cooling and limit disruption to the residents, cooling was added centrally by adding a new cooling direct expansion (DX) coil to each of the central air handling units served by an air-cooled rooftop condenser. The design optimizes existing infrastructure, leveraging the building automation system for seamless temperature and humidity control. The project was completed in time to be operational for the first heat wave of the summer of 2024. This project aligns with climate adaptation goals by mitigating extreme heat impacts while prioritizing resident well being and ongoing operational efficiency. Company: H.H.

ROBSON STREET HERITAGE FACADE RETENTION

Amacon Developments, in conjunction with the City of Vancouver, retained an existing facade as part of a new mixed-use development tower project. The existing structure, which dates to the 1940s and is of high heritage value, was incorporated into the new towers’ structural form and details. To preserve the approximately 460-ft long by 40-ft high reinforced concrete and masonry facade in-situ and to allow for an excavation for 9 levels of below-grade parking, Amacon developed a design-build scheme for a temporary shoring system to fully support the vertical and lateral load demands. Additionally, this project overcame site-specific challenges like a narrow alley on one side and above- and below-grade utilities, while ensuring accessibility to build. The company chose steel shoring frames on micropile-supported bases to support the approximately 320 tons of facade weight. The entire design to erection process was fast-tracked and completed in 10 months.
