First, we'll discuss the various uses and the dreams you have in mind for your new steel building, and design it to suit your needs. We will then start the process to obtain the necessary permits to begin construction.

Next, we'll coordinate the site work that's necessary for your new metal building, from the excavation of the property, to the concrete or masonry work needed for the foundation, as required by your local township or municipality.

We will then schedule for our experienced and qualified metal building erection crew to be on site, to begin the process of erecting the pre-engineered steel building, that was designed to meet your specifications.

Finally, we'll coordinate the final details of your metal building. This would include any drywall, painting, electrical, plumbing, HVAC, sprinkler installation, etc., that is required to complete your new steel structure.  We're happy to provide and supervise.
