Your Work, Our Pride

G.H. McCulloch, Inc. will help you design, build, and maintain industrial work of all types and complexities. Whether you’re working on a new construction, an addition, or just need repairs, our focus is to have quality structure installed safely on or before the scheduled deadline. Our highly-experienced and resourceful team of professionals accomplishes collective design, modeling, and fabrication goals by successfully integrating with your project team’s culture.

We also take a more proactive approach during the pre-construction phase. By working hand-in-hand with the project team, we’re better able to understand their desires and produce more resourceful, cost-effective results. This allows us to control the outcome and success of a project much more efficiently. Our pre-fabrication capabilities allow us to deliver projects quickly and proficiently.

When it comes to designing and building your project, we take a look at a few key factors to help us reach maximum efficiency:

  • Risk management
  • Budget control
  • Project delivery schedule
  • Accessibility
  • Integration

When you work with us, you’ll quickly realize how effective in-house professional engineering and fabrication can be, and how much more control, accountability, and budgetary relief you’ll have on a daily basis. More importantly, you’ll know first-hand that you’re backed by an experienced team that will deliver you a high-quality final product.


Four major areas of communication focus:

  • We use Building Information Modeling (BIM) to explore projects’ crucial physical and functional components before we began to build anything.
  • We use a proven process to achieve execution professionally and successfully.
  • We employ the use of new technologies that help maintain efficient sharing of information.
  • We continue to hold open dialogue every step of the way.
