Construction runs on communication. Superintendents, foremen, subcontractors, suppliers, and project teams make countless decisions through phone calls and conversations every day. The problem is that those decisions don’t always make it into project documentation and a seemingly small missed detail can lead to expensive rework. In this episode of The ConTech Crew, Jeff Sample sits down with Karly Heffernan and Alena Tuttle, co-founders of Hardline, to explore how technology can capture the conversations already happening in the field without forcing construction teams into entirely new workflows.
They discuss Hardline’s origin story, including the communication breakdown that resulted in $150,000 of rework, and explain how AI can turn everyday calls and site conversations into actionable project documentation. The conversation also goes beyond efficiency to explore what giving superintendents time back could mean for mentorship, knowledge transfer, workforce development, and the future of construction.
