Tusayan Shuttle Parking Lot
The Federal Highways Administration (FHWA) contracted with West Point Contractors, Inc. (WPC) to build a new trail head and parking lot in the Kaibab National Forest at the north end of the gateway community of Tusayan, Arizona. The parking lot design created 100 new spaces, serving both as parking for the Tusayan Greenway as well as additional parking for those choosing to park and ride the National Park Service’s seasonal Tusayan shuttle. The parking lot also serves as a trail head for the Arizona trail, which stretches more than 800 miles from Mexico to the Utah border through Arizona’s canyons, deserts, and forests. WPC self-performed over 60% of the construction scope of work using heavy earth moving equipment, cranes and paving machinery to construct and install drainage structures and structural concrete, cattle guards and restroom buildings; underground utilities; ABC and asphalt paving; traffic control, striping, hydro-seeding, decorative concrete, signage, and ADA accessible walks and paths. In addition to the majority of the construction activities, as the prime contractor, WPC was responsible for design management, general conditions, constructibility reviews, value engineering, CPM scheduling, project management, quality control, site supervision, and safety implementation and enforcement. This project required coordination between all concerned parties: National Park Service, Forest Service, AZ DOT, FHWA, the Tusayan community; and other contractors working in the project area. Weekly meeting were held to address upcoming construction productions to avoid any possible conflicts. Coordinating highway milling and using the milling as sub-base for the project provided savings for both ADOT and FHWA, as it eliminated costly transport and dump fees by incorporating a recycled product into the construction of the new parking lot facility (value engineering).
