Appellation Construction Services (ACS) has built a reputation for completing complex mechanical piping projects.  ACS prides itself on executing critical outage and completion dates on time by continually exceeding its customers expectations through careful planning.  We have dedicated, innovative and hardworking  teams from the main office to project managers, estimators, supervision, fabrication shop crews and most importantly the safety department who understand the challenges and demands of today’s construction.  We have the experience and expertise to make educated timely decisions to solve any challenge that may arise and deliver safe, cost effective quality services to our customers

ACS has an advantage to layout, build, hydrostatically test, and paint/coat piping under roof in our fully staffed 85,000 square foot shop while field construction is simultaneously completing the site work in preparation for piping installation. Our 3D laser scan capabilities allow us to verify dimensions on existing facilities to ensure accuracy for our customers. This enables us to reduce schedule, increase productivity, and provide savings to the customers. With the addition of our state-of-the-art sub-arc welding process, our fabrication facility can increase deposition rates with faster travel speeds and produce high quality welds much more efficiently compared to other welding processes. The fabrication shop can handle pipe exceeding 60 inches in diameter and thicknesses exceeding 4 inches.   We also hold an S-Power Boilers, U-Pressure Vessels, and R-Repair stamps certified by ASME (American Society of Mechanical Engineers) and NBIC (National Board of Boiler and Pressure Vessel Inspectors) for pressure vessel,  boiler repair and construction with pressure ratings up to 10,000 psi.
