The quality of a Scan to BIM model is one of the most important factors when you choose a BIM services provider. There are no standards to stick to, nor any tools that automate this task. However, at ViBIM, we always prioritize quality over everything. Thus, we build effective Quality Assurance / Quality Control (QA/QC) process for every Scan to BIM project.
The main idea for the article is to offer you a general understanding of the QA/QC process. Besides, we want to share how we conduct the QA/QC process for Scan to BIM projects with you. Hope that this can assist you when you have to control the quality of a BIM model created from point cloud data. Let’s keep reading to find out more information.
1. Why is Quality Assurance / Quality Control (QA/QC) needed?
The process of creating a 3D BIM model involves several steps. At each step, there is more likely to appear inadvertent errors. These errors can impact the accuracy of the final model. It’s why we need to conduct the Quality assurance / Quality control (QA/QC) process. This ensures that you get a high-quality BIM model. By undertaking the QA/QC process, you can
- Eliminate errors, clash issues in the process of modeling;
- Assure to follow the standards while creating BIM models;
- Ensure enough geometric elements, the correct position, functionality;
- Make sure that a BIM model meets the client’s accurate requirements;
2. What is the QA/QC process for Scan to BIM projects?
Quality Assurance (QA) and Quality Control (QC) are two concepts that are often used parallelly. Although they are the same, there are distinct differences between the two concepts.
Quality Assurance (QA) shows you how a BIM model is created from laser-scanned point cloud data. In other words, the QA identifies standards or methods that need to be followed to meet the client’s requirements. The QA is often used to monitor and verify how you are doing is right.
If the QA is a process to create the deliverables, Quality Control (QC) is the process to verify those deliverables. The purpose of the QC process is to identify and fix errors, clash issues between building trades. The QC process makes sure the results of what you’ve done are what your client expected.
In general, two terms are related to each other but they are different in the purpose. The QA process focuses on preventing errors whereas the QC process aims to determine and address the errors.
3. How does Quality Assurance / Quality Control (QA/QC) work?
The QA/QC is one of the indispensable parts of our Point Cloud to BIM projects. The QA/QC process is always conducted during the modeling process and before delivering the final BIM models to the clients. We define specific QA/QC processes for both Architectural and MEP disciplines. Let’s get into the juicy details.
QA/QC process for Architectural building system
The QA/QC process for the Architectural building system currently involves key three checks. It includes the quality checking by Naviswork, Revit, and the final step after detaching the file. Checking by Naviswork ensures that the BIM models are enough building elements, in the correct location, and don’t have any clash issues. Besides, checking by Revit makes sure that the BIM models are the correct structure and functionality.
The QA/QC process will begin once after having already finished the process of modeling. The QA/QC specialist can undertake two processes (Revit, Naviswork) parallel to each other before moving to the final checking step. After having already completed the QA/QC process, we export the file and create a QA/QC checklist to send the client for confirmation.
Curious about the Quality Assurance / Quality Control for Scan to BIM projects?
Our QA/QC specialist is here to help you understand better the QA/QC process for the Architectural and MEP system.
QA/QC process for MEP building system
Like the Architectural discipline, the MEP system has also its own QA/QC process. This involves two main reviews including geometry checking and structural checking. The process assures that the BIM models are enough geometry elements, the correct structure, connection, and don’t have any clashes. The software for the QA/QC process includes Revit and Naviswork. Also, the QA/QC specialist will conduct the final checking step to get a quality BIM model before delivering it to the client. Let’s take a look at our QA/QC process as described below.
Quality is a key part of any Scan to BIM project you need to focus on. The QA/QC process ensures that you get a clean, ready to use BIM model. If you have any concerns relating to our QA/QC process, feel free to let us know. Our BIM consultant is here to assist you to answer any questions until you get what you need.
