His project experience includes highway, railroad,and mass transit tunnels; railroad, urban transit, and rural highways;and bridges. Doug was responsible <strong>for</strong> the systems integration <strong>for</strong> the I-70Hanging Lake Tunnels in Colorado, which included a semi-transverse ventilation system with vane axial fans and a completetraffic monitoring and control system. He is presently acting as Systems Integration Lead <strong>for</strong> the Caldecott Tunnel ImprovementProgram, currently under construction on SR 24 in the hills above Oakland, CA.This project involves constructing a fourth bore through the Berkeley Hills near San Francisco. Tunnel systems <strong>for</strong> thisproject include a longitudinal ventilation system; tunnel fire detection systems, including linear heat detectors andCO monitors; redundant power supply systems, including dual power feeds, uninterrupted power supplies (UPS), anddiesel generators; tunnel lighting; supervisory control and data acquisition (SCADA) systems; emergency call boxes;and a traffic operations system (TOS) that included closed circuit television (CCTV) camera coverage, traffic signs andsignals, radio communication systems, and access control sensors. Doug managed the preliminary design and finalplans, specifications, and estimates (PS&Es) <strong>for</strong> the tunnel’s mechanical, electrical, and traffic control systems. He wasresponsible <strong>for</strong> the development of the overall tunnel operations and controls plan. Doug coordinated the overall systemsdesign and operator interface, and is providing oversight <strong>for</strong> the systems integration and acceptance testing.Glenwood CanyonTunnels,Glenwood Springs, COProject Owner:Joe Elsen, PERegion 3 Program Engineer(970) 384-3332Los Angeles CountyTraffic OperationsSystem, Los Angeles, CAProject Owner:Greg Damico, PECaltrans Project Manager(213) 897-9047This project involved providing preliminary engineering services, final design, and CM <strong>for</strong> a multimillion-dollar tunnelingef<strong>for</strong>t through the scenic and environmentally sensitive Glenwood Canyon area on I-70 in western Colorado. As part of a12-mile, four-lane final link on I-70, the project consisted of three elements - a 3,625-foot-long exploratory tunnel; thetwo-lane, twin-bore, 4,000-foot-long Hanging Lake Tunnel; and the 640-foot-long Reverse Curve Tunnel. Doug ensuredthat the systems requirements <strong>for</strong> fire life safety were in accordance with NFPA 502 and developed the emergencyresponse plan. He managed the team of mechanical, electrical, traffic, and systems design specialists <strong>for</strong> preparationof PS&Es <strong>for</strong> the integration of tunnel systems. During construction, Doug provided overall management <strong>for</strong> the systemsinstallation inspection team, per<strong>for</strong>med systems factory inspections, and supported systems integrated start-up testing andcommissioning.<strong>Parsons</strong> provided planning and final design services <strong>for</strong> the traffic monitoring and control system <strong>for</strong> five individualfreeways in the Los Angeles County area. This network was an element of the Caltrans District 7 TOS network, providingregional traffic monitoring and control through a high-speed, fiber optic communications system to provide a robust,fault-tolerant communication network. Doug managed 10 PS&E packages <strong>for</strong> the traffic communications, monitoring,and control systems on three freeways. Doug prepared site surveys <strong>for</strong> new and existing utilities and plans in accordancewith Caltrans’ standards. He also integrated the TOS elements, including CCTV cameras, variable message signs, weighin-motionsystems, traffic detector stations, and a communication data network.23
