The era of Building Information Modelling (BIM)
has arrived. Since the past few years, this term has become amalgamous to the construction
industry. BIM is not simply the virtual modelling of a building; It is a key
that enables information to be shared among parties in a construction project.
This system is often adopted by construction companies to improve the 3 most
important aspects to their projects, namely time, cost, and quality. BIM covers
the whole construction lifecycle from the briefing stage all the way to the
operation and maintenance of a building. Generally, the application of BIM is
divided into 3 levels, starting from Level 1 with minimal collaboration between
parties up to Level 3, where all parties collaborate on the same model and
share the same data on the same repository.
As the industry shifts
towards the massive use of BIM softwares for construction, the industry
professionals, including the Quantity Surveyor, has taken a step forward to
fully utilise the benefits that can be obtained from BIM. Several BIM QS
softwares on the market can now enable a QS to easily take off quantities and
estimate the project costs from any drawings or models available. As BIM is
more than 3D-CAD, information such as Schedules and Cost plans can be included
in the files. This speeds up the process of rectifying errors and accommodating
variations throughout the project, thus reducing the time needed to tackle
mishaps. By taking off quantities using BIM, no time is wasted on the lengthy
process of manual measurement, not to mention the increased precision obtained
from software measurement.
In this assignment, we researched about the available QS BIM Softwares in the Market, and compared them side by side to discover their benefits and limitations. We also compared the various methods of taking off - manual, CAD, and BIM - throughout different construction stages.
