Clash Detection

We believe in uplifting our client’s plans to the next level, and that starts with the efficient optimization of project resources including accurate clash detection. We use clash detection software Autodesk Navisworks to help us in the coordination with 3D to achieve the best design build solution and create detail clash reports during the design stage to helps our clients enable complete construction life cycle streamlined and full proof gaining potential benefits including time, money, and effort.

COMMON CAUSES FOR CLASHES

When all the stake holders - Architects, Structural engineers,MEP engineers, Environmental engineers, and other professionals- create design models, independent from each other andwhen they integrate ]into the BIM modeling process, clas detection comes into the picture.

Clashes in construction quite a common occurrence and it cost the construction company dearly. Rework and material waste contributes up to 7.25% to 35% of total project cost and increases construction time. Therefore, it's advisable to detect clash points early to avoid unnecessary expenses and delays.

Clashes occur due to:

Intersection of components of different disciplines sharing the same space
Lack of buffer space around equipment
Conflict between workflow and equipment scheduling
Types Of Clashes
Hard Clash comes in scene when two components of a building share the same space. A duct running through a plumbing line, electrical wires or any pipework crossing through a steel beam are examples of a hard clash. out of all the types of clashes in BIM, hard clashes are most prominent. Hard clash detection can be detected based on geometry or semantic and rule-based algorithms with embedded information on the BIM object. For geometry-based detection, tools like Navisworks identify clashes like a beam running through a pipe whereas the rule-based clash detection on embedded object data eliminates the common mistakes likes pipe running through a wall or MEP against ceiling.
When an element is not given the spatial or geometric tolerance, it requires or its buffer zone is breached, it results in Soft Clash. Spatial tolerance requirements are common in MEP services to facilitate maintenance at later stage. For e.g., an air conditioning unit may require buffer space from a beam for safe and easy maintenance access. Soft clashes if left unattended can cause maintenance problems and safety issues. For instance, if a live wire passes by a plumbing line, there is always a risk of having issues of circuit completion or short-circuit. Providing sufficient object related tolerance data to software like Navisworks can identify clashes as per applicable regulations and standards. This would especially apply to high occupancy places like malls, airports, and healthcare facilities to ease operational maintenance.
Workflow or 4D Clashes involve clashes of contractor scheduling, equipment and material delivery and general workflow timeline conflicts. Unlike hard and soft clashes, 4D clashes result from scheduling clashes of inter-disciplinary activities that eventually lower the efficiency of the entire construction firm. Since one clash has a cascading effect on several disciplines and can bring work to a standstill, contractors cannot afford 4D clashes. Developing a 4D construction sequencing timeline in Navisworks points out the start and end date of each activity and helps the contractor schedule the activities accordingly. A systematic step-by-step phasing in 4D BIM eliminates the possibility of encountering any workflow clash and avoids site downtimes to keep up the man-efficiency of the task force.
Clash detection in BIM is crucial and valuable. The association of Construction and Development estimated that industry-wide, each identified clash saves about $17,000 on a project, and on large projects, 2000-3000 clashes are usual. That means it's an easy saving of $34,000,000!

WHAT HAPPENS IN BIM CLASH DETECTION PROCESS?

The clash detection process by using Autodesk Navisworks, identifies where the independent models clash with each other- finding where elements from one model overlap the elements of models from other architect-engineering design disciplines. Clash detection ensures every aspect works hand-in-hand and nothing is incompatible.

BIM clash detection has brought fresh air to an ailing industry that often faced issues like project completion delays, escalating budgets, and last-minute surprises due to incompatibility between various designs.

With time and cost assurance provided by the usage of BIM inside the project gives engineers confidence and they are open to considering BIM alternatives. Additionally, you get more Happy Clients with design flexibility.

In the past, clash detection wasn't a pre-meditated endeavor. Engineers would supervise construction on the site itself and when a clash emerged- e.g. a beam coming in the path of air conditioning unit, everything had to be scraped and the whole construction design had to be refined on the spot. This led to costly delays, creating a need for clash detection at the design stage.

BIM makes it possible to create detailed clash reports during the design stage itself. Modern 3D graphics truly made the clash detection process streamlined and full-proof. Architects and designers can now detect clashes during the earliest stages of design.

Unlike the traditional design process that would involve overlapping designs made on tracing papers, the computerized BIM process evaluates a large number of federated models at the same time and makes it easier for BIM, structural, and MEP coordination for integrating all the design information into a master model. Using automated integration, architects and designers can identify and analyze all the instances of clashes in their model when all other models are combined into a single entity.
