When you convert it into IFC file format after 3D designing a building using a BIM authoring tool such as Autodesk's Revit, missing objects are often found. In other words, the object you could see in Revit are missing when it is converted into IFC file and then imported it. To get more accurate modeling result, we need to check the missing data and correct them in Revit.
Concept of BIM data Integrity Check
Detailed process of BIM data Integrity Check using performa IC
1.
When IFC file is exported after BIM designed, Revit data (NIC file) are generated through Revit Plug-in and the NIC file's Integrity can be checked.
2.
IFC file is imported in performa IC.
3.
The IFC data are compared with Revit data and their integrity is checked in performa IC.
4.
In performa IC, the missing data can be detected and the result reported.
5.
The missing data are checked in Revit by clicking the Integrity Check button.
6.
The missing data are corrected in Revit.
Missing Object data expressed in performa IC
Example #1
You can see the Roof object in Revit, but it is missing after it is exported into IFC file and then imported again in performa IC. performa IC visualizes the missed object in 3D. Revit

Example #2
You can see the Window mass object in Revit, but it is missing after it is exported into IFC file and then imported again inperforma IC.performa ICvisualizes the missed object in 3D.

performa IC (Integrity Checker) is mutual BIM data integrity checking feedback system.
▶ Functions of performa IC • Visualizing property and shape information of BIM model big data. • BIM authoring tool's (Autodesk Revit etc.) integrity feedback plug in. • Visualizing the missed objects • Analyzing the integrity objects by type
When you check or manage a building with BIM software, if the building is BIM-designed, you can see 3D images and get various information of building objects as if you are really in the building looking at them. performa Manager has "Navigation Map" and "Walk Through" functions as well as Building Object Search function. Through these functions, user can get the information of building objects using virtual navigation and virtually walking through every each part of the building.
Building Object Search
This video is showing how to search building objects through IFC BIM Viewer of performa Manager which can also express detailed information of the target objects.
Navigation Map & Walk through
The inside and outside of the building are visualized in 3D, and 2D-floor plan (like a 'map') by level is also presented in the 3D View. The red spot is like camera and the triangle area is like camera angle.
This posting is to introduce ‘performa BIM
Model Server' of Quartz Sys.
It can import IFC Data from the design
information of buildings modeled with big data BIM and extract 3D shapes &
property information of buildings. performa BIM Model Server stores and manages the information by object in DBMS model server through our
high-speed IFC parsing engine which was certified by International
buildingSmart for the first time in Asia.
performa BIM Model Server also has
capability to provide other systems with 3D shapes & property information
of the BIM- designed objects, which have been stored in the server, through
OpenAPI service based on Restful.
Major functions of performa BIM Model Server are as follows:
1. Open BIM Data files interworking the projects with Googlemap
2. Store and Manage the information of objects and express the detailed property information of objects.
3. Visualize BIM Data in 3D in web environment including MEP information.
