Abstract :

Demolition is the tearing down of buildings and other structures for the beneficial purposes. Here the word management refers to coordinated works of demolition and renovation works with respect to time frame. The main objective of construction management is the cost effectiveness in conjunction with safety measures during construction. A good number of buildings, structures in south-western region of Bangladesh were damaged due to environmental effects, such as - salinity, corrosion of reinforcement and soil characteristics. The important thing is that, in south-west region workers are locally available at low rate than south-east region. In this study, mainly the demolition and renovation works of roof slab and some other parts of a students’ dormitory (Fazlul Haque Hall) in Khulna University of Engineering & Technology (KUET) which was damaged due to salinity and corrosion of reinforcement were analyzed by critical path method (CPM). It has found that if the contractor had applied CPM at the beginning of the project the firm could have saved at least 19 days for the work items of North block which was demolished manually. Demolition management deals with the demolition of those affected structures with reference to proper management for instant safety management, time management and cost management. In case of manual demolition, it requires more time than mechanical or explosive demolition. Moreover, it is difficult to maintain time frame because concrete strength is not same in each and every section so it is difficult to predict required time to demolish the structure.
