For high productivity during project lifecycle it is
crucial that design and construction professionals try to sort out all the
clashes which are either based on design or on time. All kinds of clashes are
very harmful for the productivity of Architecture, Engineering and Construction
professionals who hold the responsibility of constructing a building on time. Design
and time based clashes can be considered as the main obstacles for architects
and engineers when it comes to the late accomplishment of the building project.
Architectural, structural and MEP design is
represented by design and construction professionals through digital parametric
models which are extensively produced with the support of 3D modeling software
Revit. The parametric models created through Revit Architecture, Revit
Structure and Revit MEP services, are highly indispensable for architects and engineers for
curtailing design based clashes. If design and construction professionals want
to compare multidiscipline elements in context of determining design based
clashes between them, it can be accomplished in Navisworks Manage which are is
also designed by the same manufacturer which has developed Revit. That means Autodesk
product Navisworks is also very important for those professionals which are
associated with AEC industry as it helps in determining clashes between the
elements of 3D Revit models which are developed for different building
disciplines.
That means only 3D BIM remains relevant for AEC
professionals when they have to identify design based clashes. On the other
hand for finding out time based clashes design and construction professionals
will have to execute 4D BIM modeling, wherein one more dimension is included in
3D BIM. Time remains the new dimension of 3D BIM and hence all the information
associated to time requirements of the building project can be obtained from 4D
BIM. So as design based clashes or collisions are identified by AEC
professionals through 3D BIM, similarly time-based collisions can only be
pointed out and rectified through 4D models.
The very phrase ‘flawless construction’ becomes an
actual practice if both design and time based clashes are effectively sorted
out in preconstruction.
