Pinnacle Engineering was retained by a major aggregate handling company to provide earthwork design, rail design, drainage design, wetland mitigation design and environmental permitting services, and construction oversight for a facility capable of processing 400,000 tons of frac sand products per year. The facility is located adjacent to a crude oil rail loadout terminal in North Dakota.
This project involved the design of four service tracks totaling 8,600 feet of rail that service a quad-silo loading facility, and a 2-acre mobile transloading pad area. Soil cement was used to stabilize many of the heavily traveled trucking areas, increasing the durability and life of the truck roads while minimizing construction and maintenance costs. Pinnacle permitted and designed a new rail crossing of an adjacent County road, including replacement of the roadway pavement with concrete through the area of the newly installed crossing and two existing crossings. Pinnacle also prepared facility plans and specifications and submitted those to the railroad serving the facility for approval.
Pinnacle secured all required local, state and Federal environmental permits, including a wetland fill permit and construction stormwater permit. In addition, Pinnacle formulated the construction SWPPP and conducted required inspections during the construction phase of the project.
Pinnacle provided on-site construction administration and observation services, survey staking, management of materials testing activities, and field design change services through final completion of the project in the summer of 2014.
