As a firm providing extensive solid waste management services, incorporating surveying capabilities into our projects allows us to be more efficient and provide higher quality work. Whether there is a need for a topographic survey to initiate project design, construction staking, or project documentation as-built records, Aquaterra can handle it. Having in-house surveying lead by a Professional Land Surveyor, allows Aquaterra to internalize the sometimes difficult task of coordinating with a third party surveyor, thus leading to more timely information during the construction phase of projects.
Aquaterra was retained in 2011 by Republic Services, Inc. to provide surveying services for the final closure project at the Ellis Scott Landfill near Clinton, Missouri. Site control was established by Aquaterra using previous site plans and was used for the duration of the project. An initial verification survey based on a pre-determined grid system was performed to establish the existing grades at the site prior to any grading. Upon completion of the grading/excavation, a second verification survey was conducted on the same grid to document that the design elevations had been reached during excavation and grading. A gas collection system was installed concurrently with the site grading. All well locations, header and lateral piping, sumps, and other components of the gas system were staked out for the gas collection system installation contractor. Following completion of the gas system installation, all pipe associated with the gas system was surveyed to document location and depth of the pipe as well as to verify that the pipe was placed in a manner that maintained the design slope. The final survey was a topographical survey conducted prior to the placement of the geosynthetic components of the final cover system. Following the placement of the geosynthetic liner and protective/vegetative cover soils, a final grid survey was performed documenting the depth of the protective/vegetative cover soils. As-built drawings of gas system and final cover components were produced and submitted with the final CQA reports to fulfill third-party verification requirements.
