In-House Control Saves Time and Money
When you hire Parks as your general contractor, you hire us for the entire job. Our employees do nearly all the work at your site. We maintain a single source responsibility for the in-place building system. Because we maintain better control over the entire construction, you win by meeting timelines faster and controlling the budget better.

Better Designs with "VP Command"
Parks is an authorized dealer for Varco-Pruden (VP), one of the largest and most respected names in pre-engineered steel building construction.

We can build a structure down to one-eighth of an inch in any direction! These precise designs can be constructed thanks to our "Custom Concept" pre-engineered steel building system. We can meet the developer's requirements in size, design, and shape. 

VP utilizes the most advanced computer technology in the industry. VP Command is a proprietary design, engineering, estimating, and ordering program. Working together with architects and engineers, VP Command accurately details building structures while reducing both estimating and design time.

VP Command offers these features:

  • Enhanced project control
  • Virtual tours and Architectural Renderings
  • Accurate project pricing
  • Anchor bolt layouts and reactions
  • Preliminary designs and Erection drawings
  • "What if" scenario capability to compare alternative designs

If you're looking to give an old building new life, consider our "retro-fit" roof systems!  We are a certified AEP Span "retro-fit" metal roof contractor.

  • We can put an entire new roof on a new addition to your building and continue the design over the existing structure.
  • We can replace or reside existing steel roofs. We employ a concealed clip concept rather than the traditional screws through the panel.  This enhances the finish and allows more durability. This type of roofing can cover existing panels with ease.
  • Best of all... you won't have to stop your business in order for us to construct your new roof!  We do it quickly, efficiently, and quietly!
