RTD - 711 Customer Service Building

Project Overview

Originally a Burlington Northern railroad maintenance facility, RTD's 711 Building was a vacant, historic brick structure in need of major restoration. A.D. Miller transformed the 55,000-square-foot building—once marked by fire damage and aging infrastructure—into a modernized space that honors its industrial legacy. The eight-month project was completed under budget and ahead of schedule. Restoration included reinforcing the high-bay timber and brick structure, cleaning and refinishing fire-damaged wood to highlight its aged character, and constructing a new addition. We installed a full warehouse build-out, generator, all-new utilities, IT/data systems, security, access controls, and redundant power backup. During excavation, our team discovered an abandoned train car leaking oil underground. A.D. Miller immediately led the environmental remediation effort, working closely with RTD to resolve the issue and protect the site. Throughout construction, we actively managed scope changes and minimized cost impacts, ultimately returning unused change order funds to the client—delivering both savings and superior results. This project exemplifies A.D. Miller's role as a trusted and proactive building partner.
