Capabilities

Design-Build

"Design-Build" is a start-to-finish, integrated design-through-construction alternative to the industry's traditional system (engineer/designer to multiple contractors to lowest bidder). This approach gives the customer a partner to work with throughout the design-build process and provides a single point-of-contact for design revisions, budgeting, equipment selection, permitting, construction, and billing.

Callahan Mechanical has an experienced in-house Engineering & Design staff utilizing the latest AutoCAD technology (AutoCAD MEP 2017, Trimble DuctDesigner 3D®, and Trimble PipeDesigner®), allowing us to produce 3D drawings for any project. These capabilities provide us with greater quality control, assist in scheduling, estimate material layouts, reduce changeorders, and play a vital role in making us a leader in the design-build market.

 

Retail Ductwork & Sheet Metal Fabrication

Callahan Mechanical excels in all aspects of commercial/industrial ductwork and custom sheet metal fabrication using galvanized metal, carbon steel, stainless steel, and aluminum. Our full-service, state-of-the-art fabrication facility includes a computer-operated coil line and plasma table, spiral machine, Whisper-Loc and Cornermatic workstation, shears, presses and rolls which allow our skilled fabricators to produce quality ductwork in a very efficient way. 

Additionally, our fabrication facility is fully integrated with the latest 3D Cad software, enabling our Design Department to create detailed shop drawings and coordinated field installation drawings for our installers and customers.
