Project Manager for the design of potable water, nonpotable water, and wastewater systems serving a large RV resort. Design included water rights storage ponds, groundwater wells, surface water intake off of the Colorado River, water treatment plant, distribution and pumping, railroad and highway utility crossings, and other features. Industrial Park Fire System, Rifle, Colorado. Conducted a detailed evaluation and water quality sampling on a 3,500 gpm pumping station and 430,000 gallon storage tank to determine the adequacy of design and construction. The extent of corrosion to the water tank and pump system was investigated. Dallas, Texas, Icon at Ross Tunnel Impact Assessment. Provided evaluation and a report addressing the potential impacts that a tunnel boring project may have on a 4 story apartment complex. The $218,600,000 project was constructed in 2016. The assessment addressed the impact of a 32’-6” diameter stormwater relief tunnel beneath the building foundation piers. The assessment addressed the 1’-3” un-reinforeced concrete tunnel lining, easements, impacts of both the construction phase and the final design phase of the project and the hydraulics of the system.
