Construction projects demand not only a good design of the structure but also a strong and solid foundation for the construction process. The first step towards obtaining such a foundation lies in knowing the nature of the soil, rock, and groundwater, as well as subsurface conditions of a particular area. In the case of the developing city of Mumbai, where residential towers, commercial buildings, infrastructure development projects, roads, bridges, and industries keep growing constantly, conducting the thorough ground investigation is an integral stage in the construction process.
The Geotechnical Investigation Survey conducted by the professionals in Mumbai helps in obtaining the necessary data regarding the physical and engineering properties of the ground before any foundation construction starts. It also provides useful information concerning the foundation, structure planning, excavations, pile driving, and other construction operations.
Accurate Surveying and Construction offers the comprehensive services of surveying and engineering specialists, including geotechnical investigations, soil tests, GPR surveys, land surveys, and many other services.
A geotechnical investigation refers to an investigation of soil and rock properties that exist at and around the site of construction through a combination of field and laboratory tests to obtain soil and rock properties including soil type, soil strength, soil density, groundwater properties, bearing capacity, and soil stratification.
A Geotechnical Investigation Survey at Mumbai would include site reconnaissance, drilling of boreholes, soil sampling, Standard Penetration Test (SPT), groundwater observation, laboratory tests, and production of a technical report.
This information is used by geotechnical engineers and structural engineers for the purpose of providing appropriate recommendations on foundations for the construction project.
Mumbai has diverse construction sites such as densely packed urban areas, coastal sites, reclaimed sites, industrial areas, and already built sites. In this regard, soil conditions may differ from one site to another.
The process of investigation may assist in finding possible ground problems prior to the commencement of any construction work. In addition, it can offer important information regarding the design and construction process.
According to geotechnical investigation guidelines in Mumbai projects, the investigation process involves boreholes, sampling of disturbed and undisturbed samples, laboratory testing, and engineering analysis.
Generally, geotechnical investigation includes a number of steps such as:
1. Site Reconnaissance
The survey team first explores the project site and analyzes the available site information. There might be a need to consider the presence of existing buildings, access routes, soil surface, drainage, development around the site, and other factors during the initial survey.
2. Borehole Drilling
Some boreholes are drilled at selected points for investigation of subsoil and sub-rock layers. The number and depth of the boreholes will depend on the type of project, site conditions, structure requirements, and the goals of the investigation process.
3. Soil Sampling
The soil samples from various depths are collected for further analysis in the lab. Disturbed or undisturbed soil samples will depend on the needs of the geotechnical investigation.
4. Standard Penetration Test
Standard penetration test (SPT) is conducted for soil investigation during subsurface explorations.
5. Groundwater Assessment
Groundwater condition is important for the excavation process, construction of basements, and foundation investigation. Therefore, groundwater investigation is an essential element of the geotechnical investigation process.
6. Laboratory Testing
Field-sampled material can be subject to laboratory testing to evaluate physical and engineering characteristics of the material. This could involve such tests as grain size determination, moisture content, density, Atterberg limits, shear strength, consolidation, and many others.
7. Technical Reporting
Field and laboratory data is then evaluated and reported in the geotechnical report. This could contain useful data and advice for foundation and construction purposes.
The geotechnical investigation survey in Mumbai can be applied to various construction and infrastructure projects such as:
Geotechnical data may be crucial for large-scale infrastructure developments since the foundation and subsurface conditions can influence the construction processes.
In contemporary constructions, there may be a need for several kinds of surveys to be conducted. Geotechnical investigation is able to be combined with GPR, topographic survey, DGPS, Total Station survey, geological survey, land survey, and many other specific surveys.
For instance, while GPR offers non-invasive information about certain subsurface features, geotechnical investigation involves soil and rocks studies. Both geotechnical investigation and GPR belong to professional services offered by the company "Accurate Surveying and Construction".
Such integration can offer more comprehensive knowledge of both surface and subsurface conditions.
Quality field investigation and data interpretation is what will define the validity of the data obtained. Hence, clients need to engage surveyors, civil engineers, and other technical experts who have knowledge about the specific needs of different construction projects.
"Accurate Surveying and Construction" asserts that it has been offering surveying and construction consultancy services from the year 2013. The firm works with civil engineers and surveyors with the help of state-of-the-art technology.
