BIM Model Auditing

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.

AUDITING PROCEDURE

VISUAL CHECK

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)
BIM model auditing
  • 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.

BIM model auditing As a result, there have been many success stories in India that defy the conclusions of the new paradox paper. Sukumar said, for example, that the population of the Asiatic lion has increased from only about 20 individuals about a century ago to over 500 today; on the other hand, the new paper says only 175 of these big cats remain in the wild. It’s a similar case with leopards as well as animals in some other continents, such as wolves in Europe BIM model auditing.

Kaul does not believe that toys, advertisements and logos “would have a significant effect on the perception of the general public on the animals’ rarity or otherwise” BIM model auditing.

“We have been arguing about how tiger-centric our conservation efforts have been, to the detriment of lesser known species,” he said. “So because our conservation is charismatic-species-centric, we are acknowledging that these species are in trouble and are investing more on them than others.”BIM model auditing.

Charismatic species also in trouble

Sukumar and Kaul also point out the differences between European and Asian perspectives, given that with the exception of the wolf, the remaining nine species considered in the study are found outside Europe. “It would have been far more revealing if the human perceptions study had been carried out in the range countries,” Sukumar said.BIM model auditing

He didn’t think the paper’s conclusions could all be disputed. For example, he said the authors have made a case to seriously consider “conservation payments by corporations exploiting the charisma of such creatures for monetary gains”.

A form of this issue was at play with Sudan, the last male northern white rhinoceros  Mordecai Ogada, an ecologist, has alleged that Ol Pejeta Conservancy, a private reserve in Kenya where Sudan had lived, had been able to raise millions of dollars off of Sudan’s plight as the last male of its kind. However, conservationists have disputed whether the ‘northern’ white rhino is a species or subspecies, and whether Sudan’s death was as significant as it was made out to be.
