How Clash in Construction Projects Result in Catastrophe?


Thousands of buildings are being constructed, and even more are being planned for construction. However, while dreaming of constructing buildings is familiar and easy, actual construction is much more difficult. This is due to many reasons, from material and budget feasibility to the wrong neighborhood and scope. Hence much care is needed to tackle every problem. Among them include clashes between different components of the building. (These can be simply solved with BIM coordination.)

What are Clashes?

Buildings are divided into three components, i.e., structural, architectural, and MEP. All these are vital and are included in projects in the planning stages. However, while doing so, they can come into a clash with each other.

All the needed strength is included in the structural part. The architectural part covers the building, protects the structural frame, and adds inside construction such as walls, floors, and ceilings. Lastly, the MEP provides life-sustaining and life-supporting systems. While they play their role, they must stay in their space to ensure smooth working. Otherwise, various disasters can take place.

Types of Clashes

The building can face different sorts of clashes. Making some blows more dangerous than others. These can be classified as brutal clashes and soft clashes.

Hard Clash

When one object comes in contact with another, this can be if two things are in the same place and thus likely to come in contact. Such as a pipe that comes next to or in connection with a beam.

A brutal clash is more dangerous than the other one and likely to cause unfortunate incidents. Taking the previously discussed example, the pipe will most likely break and sabotage the concerning piping system.

Soft Clash

This violates the geometric tolerance of an object by another object. Everything is given a geometric tolerance, a sort of buffer zone. Just as an object enters another object’s buffer zone, the soft clash is detected.

This is much lesser problematic and mainly concerned with objects that require repairing. Sufficient space should be available to allow easy and safe maintenance.

Problems with Clashes

Whether a tricky or a soft clash, it results in problems. Although these are taken care of during the planning and then construction stages, in case they last, the result:

The lowest is the object damage. For example, a wire has come in a clash. That wire breaks, and the current along with it. This can be repaired with the correct information and skill. But not all objects in a building are so simple. In case of a pipe breaks, it will flood the building with the fluid it is carrying, contaminate it, or worse.

Problems such as sparks, fires, rusting, finishing damage, and other similar ones are next. For example, the electrical wire can cause sparking and fire. At the same time, a water pipe can cause rusting of the iron nearby. At the same time, even a slight rubbing can lead to finishing damage and more.

The concerning system is devastated. Buildings have a variety of techniques that deliver some vital facilities in buildings. These relay and operate through all their constituents. If even one fails or is damaged, the whole system collapses. This means the facilities of the system become unavailable.

Architectural damage is next. This results in either floor, ceiling, or wall damage. The units used, for example, bricks, break, and fall out. This makes life inside the building complex to live and demands instant repair.

Finally, the building faces structural damage. Clash can be structural components as well as other parts of the building. This is the worst of all that leads to the wholesome collapse of the building. 


Clash can occur during the designing and planning stage of any construction project. Therefore, they need to take care of. BIM services can be helpful in this regard. These can be in any part of the building, namely structural, architectural, and MEP. Clashes are classified as brutal clashes and soft clashes. As discussed in the article, these can result in dangerous results per their tendency.
