Technology innovations enabled by collaborative contracting approaches are improving quality and efficiencies at solar construction sites. Innovations that drive improvements on project sites often are the result of collaboration between field engineers and construction professionals who have the closest view of specific daily challenges. An integrated engineer-procure-construct (EPC) contract framework can be the catalyst for such innovations because it removes barriers to collaboration that can sometimes be present in other contracting methodologies. Integrated EPC has a proven track record for improved safety, quality, cost control and schedule certainty. Now, it is also emerging as a means to drive innovations in digital technology applications applied to work on solar project sites.
