Soil Liquefaction occurs when a saturated or partially saturated soil loses its strength and stiffness under cyclic loadings such as an earthquake or sudden change in stress condition. In this phenomenon, the soil material which is solid in general behaves like a liquid. This phenomenon is most usually encountered in saturated, loose sandy soils because […]
Construction site safety is required to save the lives of workers employed at the construction site. Construction is the second-largest activity, next to agriculture in India, which employs illiterate/semi-literate migrant workers intensively. The construction sector is dynamic in nature and highly accident-prone. A small accident at a construction site may affect the entire workflow and

Geotechnical investigations are necessary to obtain information about the physical properties of soil earthworks and foundations for proposed structures. Geological Investigations should be conducted for new projects and reviewed for existing structures to determine the general geologic setting of the area at and near the project. This is also done to determine the geologic conditions

Construction of any structure progresses with the excavation of Earth to lay the foundations. Quite a few challenges are faced during subsurface excavation works. The presence of groundwater poses a major risk during construction which has caused failures of structures even before construction is completed. The process of dewatering is adopted to reduce the possibility

The very basic need of a human is shelter. The construction methods have evolved significantly in recent times. As efficiencies in both the buildings and the project are required, the modern methods of constructions are becoming popular among builders and are being adopted in a large number of projects. Modern Methods of Construction (MMC) Both
