overruns
Budget overruns are bane for construction projects as they have negative consequences on the
productivity of construction projects. The main reason of the budget overruns in construction
projects is the development of inaccurate or error prone building design which causes expensive
rework during final construction. Inaccurate building design equally involves the loss of human
efforts and useful time apart from money. But these scenarios generally occur in the absence of
the application of right tools, technology and methods.
One of the most crucial steps that can curtail all these unproductive or negative situations is the
application of BIM in building projects.
BIM’s role in curtailing budget overruns
 Project cost can be reduced drastically if accurate or error free design is developed by
BIM modelers in preconstruction which can keep a check on rework.
 Project cost cannot increase rapidly until and unless change orders or reworks are faced
by architects and engineers when buildings are finally constructed by them in actual
world.
 Since the design for multiple building disciplines is created with the assistance of BIM
software, it provides unsustainable accuracy in the design which minimizes the chances
of change orders.
 Since BIM provides tremendous advantageous for design team in terms of collaboration,
coordination and visualization, it ultimately helps in developing immaculate 3D models.
 As model elements can be viewed effectively in 3D, errors in the design can be easily
spotted and rectified by modelers which eventually translates into high cost efficiencies.
 Project outcomes can be successfully predicted by design and construction professionals
in the early phases of project lifecycle by using BIM models and if they are unproductive
they can also be controlled.
 Clash detection and coordination services which are important part of project execution
help in viewing and sorting out all the design complications in the initial stages of project
lifecycle.
 BIM also helps in estimating accurate project cost which gives a genuine idea to owners
about the amount of money they need to have with them.
 Bill of materials and material takeoffs can play a major role in the curtailment of wastage
which can otherwise lead to budget overruns.
Budget overruns can be curtailed by creating error-free design and by reducing wastage and
rework.
