Concrete pavements have been used for highways, airports, streets, local roads, parking lots, industrial facilities, and other types of infrastructure. When properly designed and built out of durable materials, concrete pavements can provide many decades of service with little or no maintenance.

Surveying is said to be heart of civil engineering. Every single activity of construction starts from survey, whether you are construction pile foundation, you need a surveyor to locate and layout that pile according to the coordinates i.e. northing and easting along with chainage, reduced distance (RD) from a bench mark. similarly the steel reinforcement … Read more
Although hundreds of stilling basisns and energy-dissipating devices have been designed in conjunction with spillways, outlet works, and canal structures, it is often necessary to make model studies of individual structures to be certain that these will operate as anticipated. The reason for these repetitive tests is that a factor of uncertainty exists regarding the … Read more
