When Brian Harlow joined Interstate Electrical Services Corporation (IESC) in 2011, the construction industry was poised for transformation. Teams were beginning to replace paper with iPads and tech platforms. Building information modeling (BIM) was on the brink of making inroads in construction. Brian recognized the power of BIM. “I’d been using AutoCAD in the engineering department when the detailing opportunity at the Operations Center opened up,” said Brian, now the VDC/BIM Specialist across Interstate’s footprint. “I taught myself Revit when there were three detailers at the company. And ever since, we’ve been learning, growing the team, and transforming how we work.” The broader construction industry is making ever-increasing investments in digital construction tools and processes. The same is true at Interstate. A family-owned company since 1966, Interstate spans six New England states with more than 600 employees. Today, with Brian as the technology lead for visual design, he is responsible for investigating new technologies that will enable Interstate to stay at the forefront of virtual design for construction.
Prefabrication advantage
Interstate’s engineers, BIM coordinators, and detailers orchestrate their efforts at Interstate’s Operations Center in Tewksbury, Massachusetts, a 100,000 square foot manufacturing and warehouse facility. Here, project coordinators and detailers fine-tune the models and install instructions to exacting detail. Fabricators assemble the units to UL Certification standards, under direct supervision of licensed electricians, and more crews package and ready the units for shipment often weeks in advance of install. Every piece of inventory is accounted for and barcoded in the system.

Winning Work
Another advantage, says Brian, is their workforce needs. As the construction industry faces unprecedented labor shortages, Interstate does more with less. Brian described a recent multi-million project requiring 14 miles of conduit to be laid underground. Two other electrical contractors that won the job backed out. They estimated needing 50 electricians to complete the work on time but didn’t have the people. Interstate, with its prefab approach, took over and completed the job with half the labor force. General contractors are taking notice. Interstate is getting repeat business from GCs who have witnessed IESC’s speed and accuracy. One such GC is R.H. White Construction. “Their projects are planned well in advance,” said Shawn Semo, Division Manager at R.H. White. “And when the materials show up on site, the documentation is all there. Installation is seamless. It has a tremendous impact on the schedule of the project. It’s just smoother.”
Workforce of the future
Transforming Interstate’s workforce has not always been easy. Many at the company have been running construction jobs for more than two dozen years. And few people are as naturally inclined to technology as Brian. While prefab has been the norm for IESC for over seven years, other coordination processes from the field to the office remained analog. Then the pandemic hit, and Brian says, “everything changed.” Interstate started moving all its projects to the cloud with Autodesk Construction Cloud. Crews communicate through Microsoft Teams. Office teams worked from home at the height of the pandemic and are moving to hybrid schedules now. Field teams coordinate with the office almost entirely by computer. “My phone barely rings now,” said Brian. “People were wary of change, but we didn’t have a choice. Some could barely turn on a laptop before, and now they’re doing digital markups.”
From elementary school to electrician
For Luiza Mills, Vice President of Human Resources and Marketing at IESC, the digital transformation of the industry changed how her team interacts with candidates – and who those candidates are. Interstate built an inclusive and comprehensive recruiting process rather than a separate program, said Luiza. “We’ve broadened our scope to non-traditional audiences like veterans, people with disabilities, women and minorities.”
