Calcasieu Mechanical Contractors, Inc. is a Louisiana-based commercial and industrial mechanical contractor known for executing technically demanding HVAC projects with discipline, precision, and accountability. From healthcare facilities and energy infrastructure to institutional campuses and public venues, CMC delivers high-capacity mechanical systems that operate reliably in environments where performance is critical.

Our strength lies in experienced field leadership, advanced coordination, and the ability to execute complex work in occupied and mission-sensitive facilities without disruption. We do not simply install equipment — we deliver mechanical systems built for long-term performance, operational continuity, and enduring value.

Project Highlights

AHU Replacement & HVAC Modernization – $7.5 Million

Fort Polk – Bayne-Jones Army Community Hospital

Calcasieu Mechanical Contractors, Inc. (CMC) was selected as the mechanical contractor for a large-scale HVAC modernization at Bayne-Jones Army Community Hospital, a mission-critical healthcare facility requiring continuous environmental control. Performing complex mechanical upgrades within an active hospital environment demanded detailed planning, phased execution, and strict adherence to healthcare life-safety standards.

The project included the replacement of nine major air handling units while maintaining uninterrupted hospital operations. Two aging dual-duct systems were converted to modern hot water reheat VAV systems, complete with new hydronic piping networks and reconfigured duct distribution. Additional ductwork modifications and replacements were performed throughout the facility, including within the emergency department. The mechanical scope concluded with a comprehensive building automation system upgrade to improve system performance, reliability, and long-term maintainability.

To protect hospital operations during equipment changeouts, CMC designed and implemented a temporary air handling solution with strategically routed ductwork to preserve indoor air quality, temperature control, and proper pressure relationships. The successful execution of this project demonstrates CMC’s expertise in healthcare mechanical construction, mission-critical phasing, and high-performance HVAC retrofits.

Industrial HVAC Systems – $2.4 Million

Venture Global – Calcasieu Pass LNG

CMC served as the mechanical contractor for multiple key facilities within the Calcasieu Pass LNG terminal — one of the Gulf Coast’s most significant energy infrastructure developments. The project encompassed HVAC systems for administrative, locker and shower, controlled access, and water treatment buildings, each with distinct environmental and operational requirements.

The mechanical systems included LG VRF equipment providing energy-efficient zoned climate control, paired with AAON Dedicated Outdoor Air Systems (DOAS) to meet ventilation and indoor air quality standards. The water treatment facility required specialized heating and ventilation installations, including industrial-grade heaters, exhaust fans, and louvers built for demanding operating conditions. CMC also installed a fully integrated HVAC controls system that interfaced with the broader plant-wide control network.

This project reflects CMC’s capability to execute sophisticated mechanical installations within complex industrial environments, emphasizing constructability, system integration, and performance reliability.

HVAC Infrastructure & Life-Safety Modernization – $4.8 Million

Burton Coliseum

CMC was entrusted with a comprehensive HVAC and life-safety upgrade at Burton Coliseum, a high-occupancy public venue that remained operational throughout construction. The project required disciplined scheduling, temporary mechanical solutions, and precise coordination to maintain uninterrupted event operations.

The scope included replacement of two 500-ton chillers, two cooling towers, four pumps, twelve chilled water air handling units, and numerous supply and exhaust systems. Associated mechanical room piping and ductwork were upgraded to support the new infrastructure. To maintain continuous cooling capacity during construction, CMC installed and operated a rental chiller system while tower and chiller replacements were performed. The project also included modernization of the HVAC control system to improve efficiency and responsiveness.

Additionally, CMC installed a large-scale smoke evacuation system consisting of eight 50,000 CFM exhaust fans connected to 60-inch spiral duct systems with intake and exhaust louvers. A fully integrated life-safety control system was provided to manage smoke evacuation events, designed to exhaust and replace the entire air volume of the arena.

This project highlights CMC’s strength in central plant upgrades, high-capacity mechanical installations, life-safety systems, and phased construction within active public facilities.

New Press Box – Phase 2 Mechanical Systems – $1.8 Million

McNeese State University

CMC was awarded the HVAC scope for Phase 2 reconstruction of the university’s press box, replacing a hurricane-damaged structure with a modern mechanical system integrated into the existing campus chilled water infrastructure.

The installation included chilled water air handling units, electric heat VAV terminal units, fan coil systems, and multiple supply and exhaust fans. Underground chilled water piping was extended to connect the new facility to the campus central plant. The project also required expansion and integration of the university’s existing building automation system to maintain centralized monitoring and control.

CMC utilized Building Information Modeling (BIM) during the preconstruction and submittal phases to coordinate duct and piping routing with structural and architectural trades prior to steel erection. This proactive coordination minimized field conflicts, improved installation efficiency, and reduced schedule risk.

The project reflects CMC’s disciplined preconstruction planning, technical coordination capabilities, and commitment to delivering durable institutional mechanical systems.

Great company to work for !!! And to get your air conditioning needs

Blake Dowden

Delivered commercial AC units to them. Very quick unload and friendly, courteous employees. Only drawback is you have to back in from the road, which is a narrow, busy 2 lane. Other than that, 👍
