Utility Investigation and Dig-Safe Marking:
Equipped with record information obtained from various departments listed above, we conduct
site visits to locate the utility structures, inspect the interior conditions and complete an
inspection form. Simultaneously, we will mark out the site for dig safe in preparation for our
geotechnical investigation. The dig safe markings by the utility companies will provide
additional information regarding the existence of subsurface utilities that our survey crew will
field-locate during their survey (if needed).
Geotechnical Investigation:
Having investigated the existing utilities and performed dig safe, we are now able to conduct
safe geotechnical investigations to determine the soil characteristics, subsurface materials,
bearing capacities, groundwater depths, infiltration rates, etc. The level of geotechnical effort
will vary depending on the general scope of each project. Given the size, scope and history of
this project site, we will conduct two days of geo-probes across the site and obtain
approximately 18 probes. Our geotechnical subconsultant will prepare a detailed report with
graphics and stamped by a professional engineer. The report will include their findings, general
recommendations for design, and anticipated challenges for the project.
We are aware that the site is built over previously abandoned wastewater
treatment lagoons. The Geotechnical investigation will obtain sufficient
information necessary for the planning and future construction of the
Synthetic Turf Fields above the closed facility. Of significant_importance is
the consistency of the materials used for fill during the 1960s.
Based on our initial research, the site is in close proximity to
the Nashua River. We will utilize GIS data to determine the
proximity of the river to the site and any wetland resources.
Furthermore, we will import the FEMA flood mapping
information to our base plan and ensure the proposed
renovations are outside of the flood plain and floodway.
Survey and Existing Conditions Mapping:
We understand that field survey is not included for the Study. We will however utilize online
resources to obtain elevations and contour data. This information will be included in the base
