Advanced Capabilities

Laser Scanning & 3D Modeling

For complex installations, we use laser scanning to capture existing conditions, develop point clouds, and model new construction virtually. This allows us to:

• Identify conflicts before installation begins
• Provide piping assemblies prepared off-site
• Coordinate with other trades more effectively
• Reduce field installation time
• Minimize disruptions to operating facilities

Assembly Services

We provide pump packages, piping assemblies, and equipment connections prepared in our shop. This approach delivers several advantages:

• Quality control in a controlled environment
• Faster on-site installation
• Reduced coordination issues
• Ability to maintain existing operations longer
• Better schedule certainty

Project Experience

We’ve completed piping installations in critical environments where failure is not an option:

• Hospital chiller plants serving entire campuses
• School boiler rooms requiring summer shutdown coordination
• Operating facilities where existing systems must remain operational
• Federal facilities with strict security and quality requirements

Union Expertise

Our pipefitters are members of Chicago Pipefitters Local 597 and Plumbers & Steamfitters Local 157. They bring decades of combined experience installing, testing, and commissioning mechanical systems across Greater Chicago.

Technical Coordination

Piping projects require careful coordination with other trades and building systems. We work directly with:

• Mechanical engineers to verify design intent
• Structural engineers for support requirements
• Controls contractors for sensor and actuator locations
• General contractors for schedule and logistics
• Building owners for shutdown coordination and testing

We update submittals and RFIs in real time, making project information accessible 24/7 to keep everyone aligned.

Why Work With Us

We install piping systems that work. Our superintendents plan every detail—from equipment rigging to system flushing—ensuring installations meet specifications and perform as designed. When you need reliable piping installation backed by experienced union pipefitters, we deliver.
