If you already have a BIM model but are unsure of its quality or want more level of detail added to it, then we can conduct our elaborate BIM auditing process for you wherein BIM models undergo our stringent quality tests to meet with the industry level standards.
Our in-house developed tools can search and identify for all components & materials missing from the model, helping you to solve these issues in advance. We can also help locate flaws and exceptions in models made by different design teams. This would help avoid expensive rework, ensuring elements of both the models match.
We can help validate your BIM models at key points throughout a project. This audit process helps to provide assurance that your BIM model will provide reliable output data and, thus, generate correct and relevant reports.
The 3D BIM models created in Revit or any other software are exported into a viewer which enables us to navigate through the modelled facility in real time and also mark the discrepancies if any. These marked discrepancies can then be accessed by the respective team mebers for further rectification. Following are some points of our checklists (these points are not a generalised form of our checklist, the project kind and scope has a major influence on our type of audit)
The models should be free of “Option Models” or “Temporary Models”. If design options or phasing are being used, then a document describing why they exist should be supplied.
Models must have a Browser Organization for views that is easy to understand. Drawing Sheets must be included but personal or temporary views to be deleted.
MEP Models should use MEP systems.
View templates shall be used for all views.
Flying or misplaced objects shall be detected through a visual check.
Models must be clean and the fill patterns, the line patterns and the object styles should be properly set up.
Models shall be accurate, following design principles. All areas / rooms should be modelled as Areas/Rooms and not filled regions with manual text. If for some special reason manual areas are calculated then this must be clearly explained on the drawing sheet.
Models must be clean and the fill patterns, the line patterns and the object styles should be properly set up.
CLASH CHECK
The Clash detection process carried out through Navisworks on the 3D BIM model prepared gives an extra insight while auditing the model, which a visual check might omit. The clashes recorded in the report enable us to visit the exact location and view the situation through an all-discipline point of view, helping us record any design changes required at those particular locations.
Following are some points of our checklists (these points are not a generalised form of our checklist, the project kind and scope has a major influence on our type of audit)
In a separate set of review models, links shall be removed and relinked by using “Shared Coordinates”. Then to be verified, if models align with each other.
Models shall have minimum, if not any, critical warnings, especially warnings related to duplicate items which would affect quantities
Checking on the screen is essential. It can be done by creating at least 2 section lines (if not more) through critical areas not already covered by the 2D prints.
Current and previous clash detection reports should be compared, highlighting major issues, resolved and unresolved.
The 3D model to be exported to .dwg and .nwc format and redlining to be done by the BIM Coordinator in collaboration with the BIM Team Leader.
Check by the BIM Team member if reference elevations, sections and details are properly linked to original section and detail and confirmed by the BIM Manager
Errors found on the screen to be reported immediately to the Senior Architect, Structural Engineer and the Technical Manager for assessing whether the issue can be solved internally or if it must be reported to the Main Contractor / Design Consultants.
NOMENCLATURE CHECK
The nomenclature of files plays a vital role in keeping the BIM files on a central platform and making it as comprehensive as possible by the file name itself. The nomenclature of the files are defined beforehand, at the initial stage or defined in the BEP of the project. These procedures are defined with an intent to ease the communication & coordination among various stakeholders involved, accessing the files of the project by making it standardised across the entire project.
Following are some points of our checklists (these points are not a generalised form of our checklist, the project kind and scope has a major influence on our type of audit)
The Revit file names shall depict the discipline and area of the facility which it represents. All revit files shall be checked for this depiction.
Linked CAD files should be used only for symbols legends, schematics & typical details.
All linked CAD files must follow the proper naming convention system and all unused CAD files should be removed.
All families shall follow family naming convention, including the generic ones.
The 3D model to be exported to .dwg and .nwc format and redlining to be done by the BIM Coordinator in collaboration with the BIM Team Leader.
All elements should have correct UniFormat and OmniClass code.
