BIM-based Facility Management Models for Existing Buildings

Building Information Modeling (BIM) is mainly used for the design and construction of new buildings. However, one main challenges facing BIM adoption existing or old buildings constructed without consideration their modeling obtaining raw accurate building data converting it to model. Based on this challenge, study develops a framework that uses different capture techniques buildings, then transforms captured into 3D models through which can improve its management processes as facilities during service life. Specifically, laser scanning were indoor data, while drones equipped with high-definition cameras (UAV) outdoor such geometric dimensions, material shapes, surfaces various shapes. Then was converted high-resolution This has been verified accuracy engineering model by two-dimensional plans three-dimensional well-known tools. Moreover, integrated Web Management System (BMS) platform. research helps in developing facility modern digital transformation aim at speeding up period using technologies. aims develop current knowledge industry reviewing comprehensive understanding how use technologies obtain information non-modeled order exploit integrate them advanced systems platforms, constitutes major progress field allowing save lot effort money future.
