CDOT Hanging Lake Tunnel CMGC

Rock solid content and a focus on meeting the needs of facilities stakeholders led to Myers gaining their first CDOT CMGC win for the recent Hanging Lake Tunnel (HLT) Garage Door Replacement project.

The HLT facility itself is a dual bore highway tunnel carrying Interstate 70 and U.S. Highway 6 through the southern wall of Glenwood Canyon in Colorado. The tunnel contains a ventilation and control structure, called the Cinnamon Creek Control Complex (CCC) which was the focus of this contract. The CCC is a partially earth sheltered structure to the west of the midpoint of the facility containing two vertical telescoping Access Control Point barrier doors that provide vehicular ingress/egress between the east and westbound tubes and to the command center itself. At the end of their service life, these 5,000 lb doors posed significant challenges for replacement and were the focus of this CMGC contract.

CDOT selected CMGC delivery to facilitate the collaboration between the CMGC, CDOT Design and key facilities O&M stakeholders. This project requires a fully collaborative effort for design, systems and constructability analysis, early procurement of specialized door systems, design and integration of SCADA upgrades, mitigation and management of potential HAZMAT, and vigilant safety planning for the utilization of confined working areas located adjacent to tunnel traffic.

“Although the scope was limited to the critical door upgrade, the continued need for access control throughout and the need for a systems specialist made this anything but a ‘standard’ project,” says Matthew Costabile, Managing Partner, “getting the right team together and then creating focused content was key to the win.”

In partnering with Myers to respond to this focused scope, Mission Critical collaborated directly with dispersed Myers team members on a daily basis to develop project-specific narrative responses as well as technical graphics and illustrations. Mission Critical identified the need for the addition of an Access Control Point (ACP) specialist subcontractor to the team, and successfully sourced and integrated this resource through the procurement response preparation and interview cycles. Our team fully designed the response document package and conducted key one-to-one interviews with aggregate team members for resume creation.

Additionally, our team worked directly with key project staff for interview and delivery preparation while developing an integrated presentation which supported the structured, situational question and Q&A segments of the interview.
