psi2Schedule and Specification Conformance

The costs of ill-timed design or material deliveries are never welcome on a substation project. PSI excels in managing its internal work and its sub-suppliers so PSI’s clients do not have to shoulder the burden of schedule management. In the same fashion, a timely delivery of the wrong equipment is of no value to our customers. PSI strives to meet our “ZERO DEFECT” goal. Our working drawings are complete, easy to read, and contain enough structural and electrical detail that fast field erection becomes a secondary benefit of PSI’s selection for your substation supply needs.

Our Collaborative Efforts Approach results in benefits such as:

  • Consistent First Time Quality
  • On Schedule/On Budget
  • Problem Solving & Solutions
  • Innovative Designs
  • Integrity in every transaction
