When it comes to the development of a project, soil testing is a critical step in the process. It might seem like a simple, routine check, but engineers understand that a geotechnical investigation along with laboratory testing of soil is the foundation of any successful construction project. By performing a thorough geotechnical investigation, engineers can identify essential characteristics of the soil, rock and groundwater that directly impact the design and construction of a project. Without this crucial data, you’re taking a risk by developing on unknown ground. If you’re looking to create a sustainable project, ensure you retain a geotechnical engineer early on to contribute to your project’s success.
Determine the Subsurface Conditions of Your Site Prior to Construction
The first priority of any geotechnical investigation is to determine the underlying soil, rock, and groundwater at a site. Factors such as soil composition, stability, and drainage are key to the design of your project. For instance, clay-rich soil tends to shrink and swell depending on the type of clay mineral, which can lead to foundation and other site related issues, while sandy soil may drain well but require modifications to ensure stability. With the results from laboratory testing, geotechnical engineers can make informed decisions about development designs and ground improvement recommendations, including adding reinforcements or even recommending relocating the project to more suitable terrain.
Identify Soil Contaminants
Soil testing also helps reveal any contamination that could pose a risk to the health and safety of future occupants. Agricultural runoff, industrial waste, or improper dumping could leave harmful chemicals in the soil. Thankfully, most forms of contamination can be addressed, but knowing exactly what you’re dealing with is crucial. A thorough geotechnical investigation identifies the extent and type of contaminants, allowing engineers to develop a plan for remediation before construction begins. In some cases, cleanup may take time, but it’s a necessary step in ensuring the safety of the environment and the residents.
Evaluate Drainage and Stormwater Management
An important issue that may be considered uncovered subsequent to soil laboratory testing is how well the soil can handle water. Poor drainage can lead to flooding, even with light rainfall, and this can seriously damage a structure and have effects on site features. The results of a soil test help engineers adjust construction plans to improve water management, such as incorporating better drainage systems or elevating certain parts of the property. Taking this proactive step can ensure that your structure remains dry and damage-free and site features function properly, even during heavy storms.
Fulfill Local Building Permit Requirements
In many areas, soil testing is mandatory. Local building authorities often require a certified soil report before issuing permits, and failing to comply can halt your project indefinitely. While this might seem like a formality, the results from a proper geotechnical investigation are crucial for both legal and practical reasons. Soil testing provides the data needed to meet local building codes and helps ensure that your project can proceed without delays. In the long run, adhering to these regulations helps streamline the building process, saving time and money.
