Munds Canyon Wash Deck Replacement
IAE Principal Josh Hewes served as the engineer-of-record for the design and construction management of a reinforced concrete deck on a single span precast concrete girder bridge in Northern Arizona. The Munds Canyon Wash Bridge is a two-lane bridge that provides the only access to private residences to the east of Munds Canyon Wash, and therefore a staged demolition and reconstruction approach was needed. One-half of the bridge deck was removed and replaced at a time allowing for a one-lane temporary traffic configuration with traffic automated traffic control at each side of the bridge.
West Fork Dolores River Bridge
IAE Principal Josh Hewes served as the engineer-of-record for the design of a single span weathering steel girder bridge crossing the West Fork of the Dolores River near Telluride, Colorado. The existing bridge was structurally deficient and functionally obsolete and served as the only access for a private residential development. This required the development of a rapid replacement scheme design that allowed for minimal closure of the road. This included construction of new abutments behind existing timber abutments and assembly of the two-girder superstructure adjacent to the alignment and then lifting into place.
While working for a previous consulting company, InterAlpine Engineers principals served as the engineers-of-record on the design of 87 rigid snow supporting structures (SSS) deployed above U.S. Hwy 89/191 near the Town of Jackson, Wyoming. This project was one of the first deployments of this type of passive constructed defense systems in the United States and required careful consideration of visual landscape impacts and reforestation across the starting zone. Client: WYDOT. Cost: $2.4 Million USD
Snow Fences at Jackson, Wyoming
InterAlpine Engineers participated in the design of semi-flexible snow umbrellas deployed near Jackson, Wyoming. IAE engineers developed design procedures for this relatively new passive defense system, and managed all aspects of the construction including foundation design and installation. Client: WYDOT. Cost: $138,000 USD

Snow Net Rehabilitation in Utah
The IAE Team provided condition assessment and rehabilitation services for an existing snow net system sited in the Wasatch Range in Utah. The passive system was approximately 15 years old at the time of the project and IAE provided field measurements of the structural components of the system for comparison with the original design, and provided specifications for the rehab work to bring the system back into fully operational readiness. Client: Private. Cost: $25,000 USD
Working as a consultant to the Colorado Department of Transportation (CDOT), the IAE Team provided avalanche hazard assessment and passive mitigation design services for a mapped avalanche path near Vail, Colorado. While the starting zone and its overall debris impacts to the highway are relatively small, the transportation route is a vital national east-west shipping corridor and also carries traffic to multiple ski resorts in the Rockies. Project is ongoing. Client: CDOT. Cost: Estimated at $2.6 million USD.

DLC Shoring Wall Design & Instrumentation in Tucson, Arizona
IAE Principal Scott Merry designed a $3.5 million (USD), 315-ft long and 34-ft tall temporary shoring wall for Downtown Links Constructors on a new roadway underpass project in Tucson, AZ. The soldier pile - wood lagging wall is supported by 3 rows of rakers and walers. A significant challenge is that the wall is offset 13-ft laterally from a Union Pacific railroad mainline, which required the implementation of a continuous monitoring system consisting of two Trimble robotic total stations, laser prism targets on the tracks, and 3-D inclinometer and force transducers on the wall. The laser targets provide sub millimeter displacement resolution.
