BIM clash detection is a process that identifies and addresses conflicts among at least two construction models in a virtual environment. These conflicts, or “clashes,” arise when different design components, such as structural elements, HVAC systems, or electrical conduits, intersect or interfere with the buffer zone of another object.
Architects, MEP engineers, and structural engineers often independently create models during the design process.
BIM clash detection highlights these clashes early in the preconstruction or design process, which helps prevent costly adjustments and delays during the construction phase.
BIM clash detection determines where design aspects may overlap and creates constructability issues so teams can resolve them before moving to the next stage.
Hired by a renowned contractor based in Florida to create a comprehensive, clash-free model for a high-end multi-story residential building.
The size of the building was 350,000 sq ft with 2 basements. G + 32 configuration.
We were engaged with the contractor and 5 stakeholders (Plumbing, Firefighting, HVAC, Civil, and Electrical) to integrate various discipline BIM (Building Information Modeling) models into a combined model. Our role was to highlight clashes and lead weekly clash coordination meetings to find the best possible amicable clash-free solutions.
Weekly, we ran clash detection, circulated clash reports to multiple stakeholders, and discussed all identified clashes. We incorporated design changes in the models based on these discussions.
These collaborative sessions allowed us to address concerns, ensure alignment with evolving design requirements, and facilitate a seamless integration of updated information into the BIM model. The result was an optimized and accurate model that met the dynamic needs of the project.
Apart from providing clash-free models, we also extracted accurate material quantities. This information aided the contractor in determining definite costs, timelines, and buying decisions.
