Construction projects often throw up clashes between multiple disciplines in terms of positioning, material or scheduling. The prime contributor of such clashes, which lead to reworks, material and manpower waste and schedule overruns, is poor interdisciplinary coordination. 2D drawings prove to be inept at detecting these clashes.
Parametric 3D BIM models in Revit are capable of visualization and real time collaboration across disciplines and geographies. They detect and resolve clashes early on in the design stage, preventing costly rework and delayed schedules.
No wonder then that construction and architectural companies around the world are adopting BIM to enhance efficiencies and ROIs.
Traditional construction drawings involve a lot of manual work which often results in irregularities and poor coordination across various disciplines. This increases instances of construction clashes, most of which get identified when the building elements are almost constructed.
Let’s look at some instances of construction clashes:
Fixing such clashes is expensive and very time-consuming.
BIM modeling software such as Revit® have built-in clash detection capabilities which help detect and resolve clashes during the design phase. Supported by clash detection tools such as Navisworks, they help reduce material waste and construction rework.

During a Level 2 BIM process, a number of federated models are produced and coordinated data drops are used to inform the master model. By using Revit BIM models and BIM integration tools such as Navisworks®, designers combine the federated models and identify clashes by running a clash detection scan. The scan produces a report that lists any duplicate instances of the same issue.
For instance, if a single run of pipework clashes with five beams, the report shows five clashes. In such cases, resolving one issue (placement of pipework) will eliminate all the clashes.
A leading architectural firm in India needed a coordinated clash-free 3D model with sheet setup, schedule and joint details for a data centre building. The BIM experts at TrueCADD studied the 2D drawings sent by the client, used Autodesk® Revit and Navisworks to develop a coordinated clash-free 3D model that helped the client leverage smooth and hassle-free documentation with a complete sheet setup. The client was able to remain within budget and ensure a cost effective construction project.
Various disciplines in the design and construction team including structural, architectural and MEP teams work on different software as per their specific usage and convenience. If these tools cannot be integrated, it results in poor coordination and project clashes.
Navisworks is an excellent clash detection software with robust integration capabilities. It promotes cross functional collaboration. Navisworks tools have built-in review and markup capabilities which help provide a real-time 360 degree visualization for a faster and more efficient construction process.
An architectural firm in the UK needed a federated BIM model in 4D with clash detection reports for a multi storey mixed use building. The team at TrueCADD assessed the technical requirements of the team and detected and eliminated interdisciplinary clashes using a coordinated model in Revit and Navisworks. Once the clashes were eliminated, a 4D BIM model and time liner video was created. This helped the client improve design intent communication with their customers, save costs and reduce reworks during the final construction stage.

Clash detection benefits through advanced and robust technology are driving project owners, contractors, architects, engineers, and stakeholders in the construction industry to embrace BIM to maximise productivity and hit higher ROIs. Coordinated BIM models and CDE help real time review and resolution of clashes, saving on rework and material costs and keeps projects within schedule.
BIM tools ensure a high level of interoperability and empower cross functional teams to interact in real-time. Different project teams can use different tools to develop their own models. Importing and overlapping those models for real-time clash detection is soon becoming a reality.
