We provide bim clash detection using autodesk navisworks.

When systems are installed that overlap reserved mechanical space or interfere with mandatory building code clearance requirements, the result is time consuming and labor intensive field rework, which leads to construction delays, manpower scheduling conflicts, and increased costs.

One example is the mechanical room layout for industrial, commercial, or mixed-use facilities. Large HVAC or pumping equipment that must be installed has to not only pass through door openings and leave clearance for future removal and replacement, this equipment will also have many piping and electrical connections that require free and uninterrupted space to make proper connections.

Another example can be found when routing instrumentation cable trays, power conduit, and HVAC ductwork throughout a facility. Each of these systems will require clear space as they pass through the building. But when MEP disciplines are not properly coordinated during the design layout phase, multiple clashes can occur during construction.

And when you consider that power panels and high or medium voltage switchgear must have proper arc/flash safety clearance for repair along with overhead restrictions from any possibility of dripping liquids, you can understand the complexities of equipment interference and installation space violations that can easily occur.

When BIM clash detection is implemented, a master model of the proposed structure is analyzed to verify the reserved floor space of all system equipment and the required X,Y,Z space coordinates of all pipe, duct work, cable trays, or +4″conduit associated with each system. In the past, systems coordination was a tedious and time-consuming process that was prone to human error. Today’s BIM clash detection software allows for an easier method to assess and resolve design decisions when an interference is detected.

During the Level 2 BIM process, the 3D model itself provides the collaborative environment in which separate disciplines can share data and spatial information. The 3D BIM clash detection software, when properly implemented will automatically flag any collisions between structural elements (walls, beams) and other geometry representing equipment, duct work or piping.

FAQs: Clash Detection


There are chances different companies use different BIM software. So to standardize there output international federation class has been created. (IFC) . All BIM software should have valid IFC data output. So if the architect is using x software and structural engineer is using y software both can be checked for clashes using there IFC outputs.
Clashes can occur during design phase as well as construction phase of construction. Causes during design phase are related to design issues. Integrated drawings need to be created before using them for construction. Errors in construction can lead to clashes.
Search sets created in Navisworks are basically rules applied to model search. These rules could be exported and imported into new project, so they may be applied and used for clash detection.
Of course yes! Clash detection can avoid costly mistakes and delays in time line. Its obvious.
BIM 360 Glue is a cloud-based platform for Navisworks. All our files stay on cloud for live updates, review and commenting for team as well as our clients. Revit files stay on BIM 360 docs and Navis files are connected to bim 360 glue.
We check models using Autodesk Navisworks, all reports are produced in. nwf files with commenting, xml files, html files and jpeg.
We are using Revit, Tekla and Navis works for clash detection process.
For AEC disciplines there are many types of clash detection required. For architecture, door, windows, finished floor, curtain walls, architectural wall. Etc. For structure, beams, columns, foundation, reinforcements, lift shafts etc. For MEP heating systems, cooling systems, equipment’s, sprinklers etc. For Electrical panels, wires, cable trays, etc. Second is interdisciplinary clash checks like Arch vs struct, Arch vs MEP so on and so forth. So in totality there are many types of clash detections required in order to have fully integrated clash free model. Clashes can lead to costly errors and delay.
