Bituminous road constructions steps: 1. Preparation of the existing base course layer The existing surface is prepared by removing the pot holes or rust if any. The irregularities are filled in with premix chippings at least a week before laying surface course. If the existing pavement is extremely way, a bituminous leveling course of adequate […]

Building Information Modeling in Construction Industry

Building Information Modeling is a system’s approach to show from design and construction to maintenance use, demolition and reuse of built assets. The first leap towards the use of 3D technology in the construction industry was marked by the introduction of 3D solid modeling in the late 1970s. During this time, manufacturing industry was already […]


1. Driven piles, 2. Cast-in-situ piles, and 3. Driven and cast-in-situ piles. Driven Pile Foundations: Driven pile foundations can be made from concrete, steel or timber. These piles are prefabricated before placing at the construction site. When driven piles are made of concrete, they are precast. These piles are driven using a pile hammer. When […]

Bamboo as a Building Material

Bamboo is a renewable and versatile resource, characterized by high strength and low weight, and is easily worked using simple tools. It is widely recognized as one of the most important non-timber forest resources due to the high socio-economic benefits from bamboo based products. Bamboo is the world’s fastest growing woody plant.
