Safe and Economical Solutions


Structural Engineering Services


Proof Engineering can help you develop steel or aluminum structures to support a variety of mechanical and electrical equipment and machinery. We'll make sure that your plant is safe and economical, complying with all applicable regulations and codes. Our engineering tools allow us to create efficient, space-saving, light-weight structures while staying within budget.  We specializing in developing  design solutions  for structural systems that have unique functions such as those that are subjected to dynamic loads, equipment vibration and shock, and wind gust and flutter.

Services Offered

• Design of new structures
• Checking code compliance of existing structures
• Forensic investigations
• Reverse engineering and detailing existing structures
• System weight reduction and optimization
• Detailed 3D CAD modeling and drawings
• Permitting
• PE stamp of approval
• Wind tunnel scale modeling and testing
• Design for vibration and shock/impact loading


We have expertise in the following areas::

• Industrial equipment and machine support structures
• Construction equipment chassis
• Pit and quarry equipment chassis
• Solar panel racks
• Storage structures

• Conveyor frames
• Below-the-hook lifting devices
• Industrial plant structures

Permit Submittals

Proof engineers can assist with obtaining construction permits for steel or aluminum structures. We can prepare a set of construction documents necessary to verify code compliance. Our submittal packages include a complete set of design drawings, full explanation of the design approach and assumptions, description of lateral and vertical force resisting systems, and documentation of any special or unique elements and conditions. This allows the reviewer to focus on key elements of the design, reduces confusion and misinterpretations of code provisions and keeps your project on time and on budget.

Special Cases

We can develop design solutions for structural systems having unique functions and behaviors such as those subjected to dynamic loads. These loads may result from:

  • Equipment vibrations and shock
  • Explosive blast
  • Impact
  • Wind gust and flutter

Client Testimonials

ViaSol Energy Solutions CEO:


We’ve been working with the principals of Proof since our company was started.  The Proof team performs so well that we have incorporated their mechanical engineering expertise into our own value proposition. After completing five complex solar projects together, and helping us develop two entire product lines, we cannot imagine working with anyone else.
