What is BIM Quality Control and Its Validations Steps?

Tweet

Quality assurance has been acting as the preventive tool which helps to obtain good-quality product and management processes by ensuring the full integration of the project scope, time, cost and functions.

How does the quality assurance for the BIM model

Quality assurance for BIM models works by following several stages which include:

General Check

General quality check helps to ensure adequate accuracy of the project components.

Space Check

This feature includes the review of the space components, areas between the spaces or the clashes between the spaces in the BIM models for the programming of the building’s space.

Design Check

This checking feature refers to the data quality checking which has been generated in the architectural design process.

MEP Check

MEP refers to the Mechanical, Electrical, and Plumbing criteria which need to be checked to detect clashes in the case of representing clashes in the architectural drawings or project schedules.

Construction Check

The structural quality of the BIM data has been checked by this construction check criteria. The clashes between the construction objects including slabs, beams, columns and others have been also detected by this checking criteria.

Model Revision

A checklist is also needed for checking the quality of the 3D models. In this context, Revit section views are appropriate for checking any kind of deviations in the design. As a result, the detection of the clashes as well as the coordination between trades has been simplified which helps to measure discrepancies. Thus, the 3D model of the BIM project has been revised.

Importance of quality assurance in BIM projects

The generation of 3D models has been done by following several steps. Each step of creating BIM models is more likely to appear errors which can impact the final BIM model’s accuracy. So, the conduction of the quality assurance process is important for the BIM projects as this quality assurance process helps to ensure the achievement of the high-quality BIM model.

Through conducting this quality assurance process:

➢ Users can find the errors in the BIM projects and eliminate those errors and other clash issues while processing the BIM.
➢ The quality assurance process also helps to ensure that all the standards have been followed while creating the BIM models.
➢ This quality assurance also ensures that there are enough geometric elements to achieve correct functionality and position.

Business values of quality assurance for BIM

➢ If a building that has been designed with higher quality standards indicates that the actual design of the building at the best case or the errors in the designs can be fixed easily.
➢ The higher quality of the building design is also more cost-effective if it is made on the basis of the design.
➢ In the building design phase, substantial savings can be made in the case the BIM model has been enriched with specific non-geometric data including heights, widths, volumes, and weights of building objects.

Environmental values of quality assurance for BIM

There are about 40% of global emissions of carbon have been done by the construction industry. So, the need for green buildings and the checking of the emissions from the buildings is necessary to maintain environmental sustainability and this can be done by conducting quality assurance procedures. The better quality indicates there is more use of recyclable materials and less waste materials.

Top benefits of using BIM models

Improving coordination and collaboration

All the stakeholders in the construction unit including the architects, contractors, engineers and owners of the construction project are allowed to collaborate effectively in real time. The BIM software allows users to access the same information at the same time by sharing a digital workspace. This helps to cut the communication errors or misinterpretations which results in the achievement of a more efficient construction process.

Construction time and cost reduction

The contractors are allowed to stimulate the overall construction procedure before beginning the construction process with the BIM models. It also helps to identify the construction errors before starting the construction process which helps to allow the contractor to estimate the accurate cost of the construction thus reducing the risks of cost overrun of costly errors. The off-site fabrication of the building components has been also enabled which helps to reduce the construction time thus ensuring that the project will be completed on time.

Increasing the quality and safety

The detailed visualization of the construction process has been allowed by the BIM software which helps to identify the safety hazards and reduce the risks of errors in the construction process thus ensuring the quality and safety of the construction process.

Improving the facility management

The BIM software is also used in managing the building facilities and building systems. This software is a valuable tool which helps to evaluate the performance of the building systems. In addition, BIM software also helps in more efficient maintenance of the building.

Improving sustainability

The evaluation of the building component’s environmental impacts has been allowed by the BIM models. This helps to reduce energy consumption as well as reducing waste during the construction process.
