Electrical
transmission line and water and sewer pipeline construction
projects can, and often do, result in excavations. In many
cases the excavations temporarily expose ancient sedimentary
rock units and their contained paleontological resources. For
electrical line projects that involve construction of transmission
towers, excavations are typically very localized with minimal
depth of grading. However, installation of pilings for tower
bases and grading for attendant roadways and substations may
result in more extensive excavation activities. PaleoServices
staff have worked on many such projects and are familiar
with the challenges posed by working with grading equipment
in such confined spaces.
Water and sewer pipelines like roadway construction projects
are linear and can provide a broad view of the geological
and paleontological record of an area. Construction techniques
can vary from open trenching to tunneling and require close
attention by paleontological monitoring staff to ensure personal
safety while still concentrating on the discovery and recovery
of unearthed fossil remains. Such projects may also involve
construction of water filtration or sewage treatment facilities
on a variety of scales from simple pump stations to major
installations.
