BIM FOR REINFORCEMENT DETAILING IN R.C.C FRAME STRUCTURES

Saurabh Kumar, Jyoti Trivedi

Abstract: As it rightly said by Ernest Boyer, “The future belongs to the Integrators”, the AEC industry is now adopting BIM, where different information related to a structure is stored in a virtual model before the structure is actually built at the site. In high rise structures (skyscrapers) BIM can play a vital role in reinforcement works as in R.C.C frame structures the cost of structure is mainly governed by reinforcement cost, therefore the level of reinforcement detailing and quantity takeoff is very critical. In this study in order to solve reinforcement related issues we use BIM for reinforcement detailing and quantity takeoff. By using BIM for reinforcement detailing we can minimize the wastage in steel and hence it can bring down the cost. It likewise provides well detailed 3-D drawings which help to visualize (especially in complicated junctions) and can solve many clashes at the site, hence saves time. In this research the results are compared to the case study of BIM vs. Non BIM approach. Bar Bending Schedule created by using BIM is accurate and can easily be changed within clicks when the reinforcement drawing changes (especially in India, where reinforcement drawing often changes to the extent of slab being executed).
