Tagline

Fabrication, installation and commissioning services for Manitoba's commercial and industrial sectors.

Custom Mechanical Fabrication

Our in-house fabrication capabilities allow us to produce mechanical components tailored to each project's specifications. This includes HVAC ductwork, process piping, and custom fittings for gas, water, and air systems. Fabricating in-house enables faster turnaround, superior quality control, and the flexibility to respond quickly to changes or field adjustments-all while ensuring materials meet provincial codes and safety requirements.

Mechanical System Installation

We install complete mechanical systems across a wide range of commercial and industrial environments, coordinating closely with other trades to ensure project timelines are met. Our experienced crews handle HVAC systems, hydronic heating, plumbing, gas lines, and ventilation systems with meticulous attention to safety, accuracy, and efficiency. Every installation is built to deliver high performance with minimal disruption to the broader project schedule.

System Testing and Quality Assurance

Before any system goes live, we conduct rigorous pressure testing, performance verification, and quality inspections to ensure every component functions exactly as intended. Our testing protocols meet or exceed local and national safety standards and are tailored to the unique requirements of each system-whether it's a high-pressure gas line, industrial piping loop, or building-wide HVAC system.

Commissioning and Project Closeout

We complete the mechanical system lifecycle with full commissioning services, which include fine-tuning equipment, calibrating controls, validating airflow and pressure levels, and ensuring all components operate in accordance with design intent. Our detailed handover packages provide as-built documentation, maintenance guidelines, and operational training so your team can confidently manage the system moving forward.
