The Survey
The client’s program consisted of a proposed well pad site, three freshwater impoundments, one flowback pit, two compressor sites and three laterals to tie into a measuring and receiving station.
The initial route selection for the pipeline was based upon the shortest distance possible. When beginning, our team developed a list of considerations in the route design. Those considerations included:
• Potential terrain obstacles including streams and road crossings
• Existing land use
• Potential surface owner conflicts
• The client’s mineral/lease holdings
• The client’s existing pipeline and compression facilities
Research & Data Collection
Following the initial route selection, our staff performed research and data collection. Research was conducted at the County Courthouse; aerial photography was used for base mapping. Data collection, including mapping of delineated streams and wetlands for state and federal permitting purposes, was also conducted.
Preliminary Field Review
Prior to commencing a construction layout survey, we performed an on-ground preliminary route review; in doing so we were able to eliminate problem areas and perform any necessary pipeline re-routes prior to the start of construction. This method allowed for an environmental site review and enabled field identification of potential wetlands, streams and potential erosion and sediment control issues. These findings were communicated to both the client’s management and the pipeline contractor.
Field Route Survey
Utilizing standard pipeline layout techniques, we performed the construction layout “boots on the ground” survey, ensuring a clearly marked route. Stationing was placed at all even stations and angle breaks . GPS terrain elevations were also collected at this time.
