"Working with Slifco Electric exceeded my expectations. During our project we had very difficult budget restrictions, and using a Design-Build/Team-Construct delivery system, Slifco Electric was able to value engineer the electrical portion of the project and save over 25% off the original electrical budget, all while maintaining the integrity of the original design intent. As the developer on the project, this gave us the opportunity to provide a higher level of quality at a lower cost and thereby pass the savings on to our customers."
