Subsurface Soil Investigations for NYC, Manhattan, The Boroughs, Nassau County, Suffolk County, Long Island, and New Jersey - Kagaoan Engineering

First, a soil investigation is given a class designation. There are three primary classes, the new structure class, revitalizing projects, and material mining. The scope, length, and composition of testing in any class must follow strict regulations to ensure that all Federal, municipal, tribal, and state laws are not broken. Once a classification is given, the five-step investigation can begin. 

The first part is reconnaissance to study the site and collect data. Next, deep boring into the soil and water table provides answers about minerals, aquifers, soil layers, and more in the preliminary part of the process. New tests or expanding studies continue in the exploration phase. Site analysis gives answers to questions about the project, ground, and water tables. This part is the stage where builders can begin to engineer structures using the information from the investigation. The final phase is to look into costs and budget constraints. 

Testing the soil for water sources and how wet or dry the ground is done by inspecting boring samples and information about the climate, aquifers, water tables, soil composition, and much more. There are four primary methods of exploration being the subsurface method that we will mainly discuss, the esoteric method, the areal method, and the surface investigation. Each of the four categories has more subsets that the engineer uses to classify the investigation. After gathering the data and reading the reports, the specialist ensures that the site meets the needs of the client or governing entity before giving suggestions and recommendations about new builds or refurbishing existing structures in the case of foundation cracking, settling, or stress. Water access for site operations is another area that geotechnical designers study for developers. 

Whether a structure is experiencing problems with shifting or showing signs of stress due to water problems, a geotechnical engineer can start finding out more about the problem by looking at information in water and soil reports. They use the data about the site along with visual inspections to help them determine the best course of action. They also ensure that solutions fit the specifications of local or national regulatory bodies. Once they have a clear idea of the problem, they provide in-depth reports to developers and construction firms to give them cost analysis of the solution and the information backing the decision. 

At some point, every business or construction company comes in contact with engineers that provide water table maps, foundation fixes or build forecasts for new structures. Residential homeowners interact with engineers when they need to build a well on private property. They may also talk with one when a house begins to settle, show signs of cracking or have foundation issues. The specialist provides information ahead of a build, to solve foundation issues, or to recommend the best methods of material collecting. 

Subsurface soil investigations and water testing methods help engineers ensure that building sites are ready to handle the construction, size, and needs of a build. They are helpful when setting up new residences, and finding out why foundations are cracking. Geotechnical engineers provide reports on water levels, soil makeup, and mineral content to help architects and building owners find the best ways to erect a new building or refurbish an existing structure.
