Shaw Engineering Civil & Roadway Projects
Wingfield Commons Offsite Improvements
Shaw has been helping Wingfield Nevada with multiple permitting and planning challenges for development of 450 units on property adjacent to Golden Eagle Regional Park in Sparks. Shaw has helped with the CLOMR/LOMR process, site topo survey, traffic analysis, sports field interfacing/screening, offsite sewer impacts including lift station reconstruction, offsite access road, offsite EVA road and city roadway reconfigurations. For the roadway component of this project, Shaw utilized Solaegui Engineers (8% of the consultant fee) for traffic impact analysis for the project. Traffic impacts were difficult to analyze due to the extreme peak trip counts for the regional park facility. Shaw, Solaegui and City parks staff collaborated to develop maximum vehicle trips expected from large tournaments and implemented these custom estimates into the overall traffic impact analysis. The project was able to be accommodated with strategically planned intersection upgrades at two of the City’s existing intersections (one signalized and one stop-control). Once traffic planning was completed, Shaw was able to move forward with design for the extension of the new road to the development as well as reconstruction of the Vista Blvd./Homerun Dr./Touchdown Dr. intersections. Reconstruction work included adding turn lanes, extending right turn lanes, adding new stop signs, reconfiguring an existing signal and pavement reconstruction. The new minor collector road included a two-lane roadway with sidewalk and a triple-box culvert drain crossing. The drain crossing had to be coordinate with the FEMA CLOMR and required guard rails and erosion/scour analysis. The emergency vehicle access (EVA) road also required CLOMR modeling coordination to prevent the road from being classified as a weir. The EVA was also aligned to avoid identified wetlands and ensure the City had maximum space for future soccer fields in the area. Preliminary design for a new soccer field complex and associated parking lots for the City was also completed. Key Personnel: Marc N.

Lovelock Paiute Tribe Water and Sewer Improvement Project
The City of Lovelock provides sewer collection service to the Lovelock Paiute Tribe. The sewer collection system had fallen into disrepair and required complete replacement. Shaw Engineering assisted in facilitating the grant that was being awarded to the City and Lovelock Meadows Water District for complete replacement of all water and sewer lines and rehabilitation of all affected streets within the Paiute Tribe land. The City was the designated entity to receive the USDA grant. Shaw provided complete engineering support from grant coordination to subconsultant utility design to complete construction management, including inspections. The project revealed many challenges such as right of way agreements with the Bureau of Indian Affairs, coordination with local tribal officials and USDA oversight. The challenges did not stop during construction with lateral reconnections across private property, dozens of unmarked/unknown found pipelines and water and sewer service stubs haphazardly placed throughout the tribal land. The City required ball valve sewer shutoffs with locking mechanisms, which added additional permitting and construction challenges that were successfully mitigated. Additional challenges throughout the project included poor roadway subgrade, complete roadway re-paving, roadway drainage and concrete repairs and connecting sewer to homes with raw sewage spilling into yards and failed septic systems. Shaw completed this mulit-agency rehab project with limited change orders ahead of schedule. The City has met all requirements of the USDA grant and the Tribe has a well functioning water and sewer infrastructure.

Lander County 2016 Paving Project
Lander County bids and constructs utility and roadway rehabilitation projects separately. Shaw has provided water and sewer rehabilitation design services for the County for over 20 years. Following completion of the utility projects, Shaw routinely provides design services for rehabilitation of the roadway. The 2016 Paving Project for Lander County provided design services for a combination of paving of gravel roads and cul de sacs in commercial and residential areas and complete rehabilitation of two streets in the commercial core of the town. 0.7 miles of gravel road paving was completed as part of the project and 0.3 miles of commercial area rehabilitation was completed. Shaw coordinated survey and provided detailed plan and profile drawings for the rehabilitation streets. This work included correcting centerline grading, adjusting the roadway profile and section to match multiple existing driveways (while staying within the right of way), designing new storm drain facilities, rehabilitation of sidewalks and curb and gutter, extensions of pedestrian routes and sidewalks, correcting ADA deficiencies, adjusting utility boxes, matching and replacing multiple types of curbs, providing mail box access and tying improvements into the Battle Mountain Hospital site improvements. The “flat” nature of the Town of Battle Mountain makes these rehabilitation projects difficult to grade and Shaw was able to correct all grading problems with limited material import of off-haul. Due to poor subgrade conditions, Shaw’s design included a cement treated base section. CTB is routinely utilized in this area to allow construction to be completed faster and also provide a cost savings over the alternative, which is a 24″+ road bed modification. Shaw worked closely with County staff to provide an efficient design to make best use of the difficult right of way while ensuring residents were satisfied.

Wildes Road (SR 118) Widening and Canal Crossing
When the Dairy Farmer’s of America began planning to build a new facility in Fallon, there was major access improvements required to meet NDOT and City access management standards. Churchill County hired Shaw Engineering to plan, permit and design a new crossing over the canal, widen SR 118 and add a new approach onto SR118 for the extension of New River Parkway. Shaw’s long history providing engineering services to the Truckee Carson Irrigation District for the BOR facilities they manage as well as Shaw’s relationships with NDOT District 2 staff allowed this project to be implemented efficiently. Shaw utilized a Solaegui Engineers (3%) to confirm the required width of the new canal crossing and NDOT approach, utilized Bigby and Associates (4%) to provide topographic base mapping and CME, Inc. (10%) to provide geotechnical recommendations for the road and bridge as well as materials sampling and testing during construction. Shaw was responsible for leading the permitting and design effort for approval of the project by NDOT and BOR. Complete NDOT design plans were prepared, including profiles, striping plan and box culvert details. Shaw also completed HEC-RAS modeling of the channel to confirm freeboard was provided in accordance with BOR requirements. The project was constructed in multiple phases with a combination of a publicly bid County project, a publicly bid City of Fallon project and major improvements by County Road Crews. Shaw was responsible for coordination between all consultants and the City, County, NDOT and BOR. Shaw also had the role construction management for the canal crossing and roadway widening project. This included daily field reports and construction coordination with NDOT. The widening of SR118 included the addition of a left turn lane and approach acceleration/deceleration spandrels. The project required winter work while the canal was off line, which caused additional challenges for NDOT paving and striping.

Gabbs Pole Line Road Rehabilitation
As part of a development agreement with Nye County, Tonopah Solar Energy, LLC (TSE) was required to reconstruct over 11 miles of County highway. Shaw Engineering came on board to provide complete roadway reconstruction drawings for the 11 mile stretch of road. The reconstruction items included pulverize and overlay, microsurfacing, and chip and fog sealing. Shaw Engineering was successful in providing a design that allowed TSE to improve the PCI of the pavement from less than 30 to over 70 at a total project cost of less than $3M. Nye County was an integrated stakeholder throughout the design process and has since concurred that the design and construction has sufficiently increased the PCI and TSE has met all terms of their development agreement. This project had many unique challenges, including Department of Energy Review (as a component of TSE’s funding), Owner, subconsultant and County coordination, and on-site resident project representative coordination. Shaw had the lead for construction management for the project and was responsible for managing the contractor’s agreement with the support of a geotechnical consultant for quality assurance sampling and testing and resident inspector, both hired by TSE. Shaw also completed a culvert condition assessment and striping and signage design. This section of highway contained multiple pre-existing design deficiencies. As part of the project, in order to limit the liability of all parties involved, Shaw conducted a highway geometry analysis focusing on design speed recommendations for existing vertical and horizontal curves in accordance with the latest AASHTO standards. These findings were presented to the County and following construction of the project, the County reduced posted speed limits for the highway. A portion of the design fee shown above (23%) was for a survey subconsultant. Key Personnel: Cody Black, P.E., Project Manager and Paul Winkelman, P.E., Principal Engineer (CM)
