Cooperation between the Architectural, Structural, and MEP collaboration involved in the building of any building, regardless of scale, is crucial. When AEC professionals apply the Building Information Modelling (BIM) approach, the constructed asset is represented through federated models developed by these numerous disciplines.
BIM’s ability to prevent, detect, and resolve disputes is one advantage. The BIM team uses Clash Detection v/s Clash Avoidance to minimize spatial overlaps and increase collaboration. These functions also ensure that some collisions occur despite the most significant attempts. Finally, after the collision has been discovered, the appropriate procedures must be carried out to address the clash for the onsite building process to go smoothly.
Introduction
Design and construction teams frequently want a streamlined way to detect and communicate design and process concerns to the right parties. Collaborative BIM between teams is critical for good management. As a result, the greater the amount of teamwork, the fewer the confrontations.
According to Plan Grid’s Construction Industry Report, clashes alone account for 5% of construction investment and 52% of $280 billion in rework costs worldwide. As a result, both Clash Detection v/s Clash Avoidance are critical components of the construction management system. But are they the same? Let’s go to the next section!
Clash Detection v/s Clash Avoidance: What is the difference?
Clash avoidance and detection are ways to minimize conflicts that are relevant at different phases of the construction procedure. It is critical to understand the distinction between collision detection and clash avoidance to eliminate clashes and conflicts during the design and construction phases, making the process smooth and objectives feasible.
Before we can distinguish the difference between Clash Detection v/s Clash Avoidance, we must understand their concept. Let’s dive into it!
What Is Clash Avoidance?
The ultimate objective is to avoid disputes, which is a more proactive procedure. Architects, engineers, and BIM modelers work together in this spectrum to guarantee spatial coordination and ensure that no overlaps occur at any intra or transdisciplinary level. It demonstrates that various strategies must be applied from the beginning of the project. Furthermore, effective communication among all project participants is necessary to guarantee that no data is lost and that each person is on the same page.
What Is Clash Detection?
In contrast to conflict avoidance, clash detection is a reactive procedure. AEC experts can employ Clash Detection software, such as Navisworks, to detect inter or intra-disciplinary disruptions. The primary goal of conflict detection is to discover any design problems during the virtual pre-construction phase so that time, money, and resources may be saved during real on-site construction.
Clashes are classified into three categories. When two factors occupy the same place, a severe collision occurs. A soft collision occurs when an object’s geometric tolerance is not satisfied, or its buffer zone is violated. Finally, scheduling issues might result in a workflow dispute.
The different abilities between the Clash Detection v/s Clash Avoidance
While Clash Detection is mainly a pre-construction activity, Clash avoidance can run throughout phases of the project. Clash detection and collision correction are time-consuming operations. The developer or the individual in charge of clash detection must iterate until the ideal design is achieved. Opposite, Avoiding clashes requires less time.
The clash detection concentration is on the clash detective tool and enhancing clash-rule sets, and only basic level coordination abilities are required. The Clash avoidance focus, on the other hand, goes beyond the instruments. The essence of collaboration between the MEP discipline and others is highlighted. It also necessitates more stringent management and coordination abilities.
Clash Detection is a one-man operation. The program handles everything. Clash Avoidance is a group activity. The awareness levels of stakeholders and AEC experts are also important in this element of detecting clashes.
Conclusion
All in all, reducing professional mistakes, encouraging co-creation, and sharing information are all significant variables in clash prevention and detection. Furthermore, Building Information Modelling aids in both clash avoidance and clash detection. It raises the amount of collaboration and increases the likelihood of clashes by fostering open communication.
However, if any clashes occur, they may be handled by using Clash Detection Services. If structural designers and MEP specialists are more open and interact on a higher level, Clash Detection and Clash Avoidance can be accomplished.
IndiaCADworks (ICW) is a leading engineering services outsourcing partner with proven expertise in BIM Conflict detection and BIM coordination services, which offer thorough clash reports and on-demand solutions to avert clashes.
