Clash detection is a very crucial part of the BIM
process. It speeds up the projects by identifying
conflicts between various models during the
designing phase. Here, clashes are identified in
all the construction disciplines like
architectural, structural, and MEP through a
computerized or automated approach. The clash
detection process is done within a 3D model with
the help of some specific software. It helps
architects and contractors to find and solve the
problems at the initial stage of the project.
Clash detection can save the project from budget
hikes and delays. It also increases the accuracy
and efficiency of the project model. Three types
of clash detection procedures can be seen in BIM
modeling hard, soft, and 4D/workflow. If you
want to increase your projects performance and
reduce the chances of errors and rework. Then

• Types of 3D BIM clash detection
• Hard clash
• Soft Clash
• Workflow or 4D Clash

1) Hard clash
A hard clash usually occurs when two or more
components share the same space or pass through
each other. It could be an intra-discipline
clash, such as a duct colliding with a pipe. Or
an inter-discipline clash, such as an air
conditioning duct inside a load-bearing
wall. Here, hard clashes are identified by
implementing the geometry, semantic, and
rule-based algorithms on the BIM object with
embedded information. Tools or software like
Naviswork efficiently determine the hard
clashes. While the rule-based clash detection on
embedded object data excludes common
construction mistakes.

2) Soft Clash
A soft clash occurs when the component is not
given the geometric or spatial tolerance it
needs. It also happens because of the breach in
the buffer zone that negatively impacts access,
maintenance, and safety. MEP services will
require spatial tolerance to facilitate
maintenance at a later stage. For example, an
air conditioning unit may need some buffer space
from a beam for safe and easy maintenance access.
Ignorance of soft clashes may cause several
maintenance problems and safety issues.
Providing necessary object-related tolerance data
to BIM software can significantly detect soft
clashes as per application standards
regulations.

3) Workflow or 4D Clash
Work-flow or 4D clashes happen due to conflicts
in contractor scheduling, equipment material
delivery, and general workflow timeline. However,
these problems are not directly connected to the
design. Still, it can significantly affect the
ongoing working timeline. A workflow clash can
decrease a projects efficiency. It also has a
domino impact that can ultimately bring the
whole project to a standstill. However, BIM clash
detection software can help contractors properly
schedule various activities. So they can avoid
workflow clashes during the project.

Some key benefits of clash detection

• It significantly reduces errors in the
  construction process.
• It decreases overall costs, material wastage, and
  mitigated risks in a construction project.
• It enhances productivity and speeds up the
  construction process. It brings noteworthy
  improvement in scheduling sequencing.
• It makes accurate estimation in all the phases of
  construction that increases the safety of the
  construction site.

Conclusion
The BIM clash detection software has brought
revolutionary changes in construction design.
They have made it simple to envision, analyze,
and eliminate clashes in the pre- construction
phases. The clash detections strengthen the
collaboration among the stakeholders related to
the project. It also brings significance,
profitability, and prestige to a construction
project. So, if you are also interested in
