Keystone XL Pipeline
Morrison-Maierle was selected by the Montana Department of Transportation (MDT), Montana Department of Environmental Quality (DEQ), exp Energy Services Inc., and TransCanada to document the pre-construction condition of the public roads that were used to construct the Keystone XL pipeline. All documentation of the site conditions was performed in accordance with the Montana Major Facility Siting Act.
Morrison-Maierle also completed the first stage of this process by documenting the preconstruction conditions of public haul roads that access nine pipe yards that were to be used as construction laydown and assembly areas. The process consisted of documenting the pre-construction conditions of approximately 1,300 miles of Montana State Highways and roughly 87 miles of county roads, and the inspection of 48 bridges within the construction route to verify if they were adequate to handle the anticipated haul loads. This haul road network is located in nine eastern Montana counties.
Morrison-Maierle also identified bridges along the haul route that were not adequate and provided load ratings for those bridges. Data collection for the work was done using a custom-designed application and done on iPads that each team used in the field. The application was developed to match the requirements of the Montana Major Facilities Siting Act and allowed inspection teams to ensure data collection was complete prior to leaving the site.
