3D and 4D BIM models are very crucial for curtailing design and time based clashes

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.

A brief account on BIM’s expansion over the years

Building Information Modeling has a dramatic history when it comes to its expansion in the landscapes of AEC industry over the years. BIM which is also known as Virtual Design and Construction has a dominant presence in AEC industry because of the fact that is has the potential to realize project outcomes and can control them significantly as per requirement. In short design and construction professionals can attain superior control over project outcomes by analyzing multidiscipline models. Well, Building Information Modeling evolved as a concept some four decades ago but it was not practiced by AEC professionals in the industry at that time. For approximately ten years since it first appeared in the journal, the term ‘BIM’ used to be seen only in research papers. BIM as a technology and a process started to be implemented in construction projects some thirty years ago. So once AEC professionals started using BIM in construction they never looked back to their sluggish performanc...

Determine the size of your family according to your project requirement in Revit!

Revit is considered the best choice by architects, engineers, BIM modelers and technicians working in AEC industry for creating families. Families are basically used by BIM modelers while executing Revit modeling services. That makes Revit and Revit modeling services an integral part of construction project execution. Family size matters a lot when it comes to designing a building. In Revit technicians have the luxury to control family size as per the requirement of their project. If in case a smaller size door is required for one of the rooms in the building it can be easily created by using the Family Editor tool of Revit. Revit Family Editor has vital features for developing custom families. The Family size can be controlled by BIM modelers by assigning required dimensions for the family.   In other words the geometry of the family can be easily controlled by assigning parameters in Revit. Take an example of door family; it’s up to Revit modelers what dimensions they want ...

Structural drawings: What is the role of Revit structure and Tekla Structure in their development?

Among all kinds of construction drawings it is really difficult to develop structural drawings as they are of highly complex nature. For developing strong and durable structural framework, the first step is to develop high quality structural drawings which can effectively describe structural design.  For the comprehensive understanding of structural design numerous kinds of technical drawings which may include detailed sketches, plans and working drawings etc have to be developed by drafters and detailers on the instructions of structural engineers.   In this blog I would like to focus on the development of Steel fabrication drawings and erection drawings which are created by steel detailers when they execute Structural Steel Detailing Services with the support of Revit structure or Tekla Structure.    Both Revit structure and Tekla structure are most widely used software packages which are utilized by steel detailers for the development of d...
