About the Project

Iron Woman’s installation of the trunk infrastructure was part of the RTD’s $1.03 billion Eagle P3 project and DIA’s $580 million Westin Hotel project. Iron Woman’s initial contract value was $65,000 and grew to over $3.3 million as we continued to add value as a project partner. In addition to Iron Woman’s strong utility team in and out of the field, critical coordination was seamlessly managed through our integrated services which included an in-house trucking group.
