Building Information Modeling (BIM) is a technological process that creates a 3D representation of a building and portrays its physical and functional attributes. Over the past few decades, the use of BIM has gained popularity among the major stakeholders in the building and construction industry. This increase in popularity has been attributed to its ability to simplify planning, designing, operation, and maintenance of buildings. Besides simplifying technical and engineering works, BIM has also influenced the regulatory and legislative (building controls) portion of construction.

Improved the Process of Issuing Permits

In some localities, BIM has been integrated into special online services to improve the ease of interaction between designers, authorities, and clients. Some of the online services allow the designer to submit BIMs to the authorities for application of a permit. To obtain a permit, the designer is required to upload an IFC model via the online service, choose the location of construction, and requests approval from the relevant authority. The IFC model often retains the information needed by the authorities to issue a permit. This makes it easier for the authorities to determine if the building meets all standards necessary to get a permit. It also reduces the time needed to issue a building permit.

Enhanced Quality Control Process

BIM has also improved the quality control process. Today’s designers and authorities have access to software like Solibri, which automatically inspects the quality of the model as well as the degree of code compliance. The software accelerates the control process and sometimes reveals errors that might have gone unnoticed if the designer used 2D drawings.

Environmental Imaging

One aspect that building controllers are usually concerned about is how a building fits into its new environment. Different localities have different building controls to ensure that the buildings fit the area’s plans and meet the environmental requirements. BIM 3D models enable designers and authorities to look at a building from different angles, see how it casts shadows at different times of the day, and determine whether it is suitable for the proposed location. If a building does not meet the planning standards or blends with its surrounding it can be rejected before it is erected.

Ease of Inspection

BIM models have also improved the ease and cost of inspection. Authorities can utilize BIM 3D images to check critical features like fire compartmentation, waste disposal system, ventilation, access and escape routes. The images could also be used to determine if the designer complied with residential regulation, as well as other building codes. Compliance with code might include the adoption of appropriate metrics/measurements for windows and doors, stairs and ramps, and waste disposal systems.


BIM has revolutionized building control immensely. It has improved the ease of issuing permits and enhanced the control process, thus ensuring early error detection. Additionally, designers utilize BIMs environmental imaging capability to determine whether a building blend with its surrounding and fits in the region’s plans. Through 3D imaging, inspectors can also determine if the designer utilized the right metric/measurements. As technology improves, BIM is expected to revolutionize other areas of building control, thus making it one of the most useful tools in the construction industry.
