Building codes comprise the foundation for constructing safely, efficiently, and sustainably worldwide. Codes like International Building Code (IBC), Eurocodes, and local codes, such as the National Building Code of India (NBC) and Australian Building Codes (ABC), provide criteria for safety, environmental performance, and operational performance of buildings.
Following these codes is not always a legal requirement, but is necessary for risk management, occupant safety, and proper life expectancy of the built asset.
However, keeping up with evolving regulations while looking after compliance in multiple locations can turn out to be a challenging task. This is where BIM becomes very useful. By incorporating compliance checks into the digital model, Building Information Modeling allows architects, engineers, and contractors to comply with applicable building codes with minimum effort.
Rule-based validation, clash detection, and digital documentation will allow BIM to reduce errors, rework-time, and ensure compliance requirements are satisfied for projects right from early design stages.
In this blog, let's dig deep into what international building code constitute, how BIM can help in following the required codes …
Building Codes in the construction industry are the stringent rules that guide the world in building, constructing, and maintaining buildings. They make certain the structures are structurally safe, environmentally sustainable, accessible to all, and very much alike in terms of the various projects. The building codes listed below are some of the most widely accepted.
This set of codes is adopted by most nations; it mainly focuses on aspects of structural integrity, safety from fire hazards, and building availability. For example, these codes allow the construction of mass timber buildings up to three stories, one of the fire safety requirements.
Eurocodes is the set of standards that govern the design and construction of buildings and infrastructure projects across all themember states of the European Union.
These standards contain critical technical specifications that are to be followed while designing and constructing buildings.
The codes developed by the International Organization for Standardization (ISO) talks about whole systems from fire-resistance to energy efficiency and even environmental sustainability.
The International Code Council (ICC) is the body responsible for maintaining a minimum level of safety for building construction. They standardize and govern model code families based on various safety aspects throughout a construction project lifecycle.
It comprises the region-specific codes such as the National Building Code of India (NBC), Australian Building Codes, and the UK’s Building Regulations.
Interpretation and application of current building codes is an arduous task owing primarily to the lengthy and relatively frequent changes in the codes themselves. Nowadays, with evolution in the aspects of materials, methods of construction, and environmental considerations, staying compliant requires a thorough grasp of multiple overlapping regulations. This compliance issue takes on a higher level of complexity with respect to projects extending across multiple jurisdictions, as differences also arise in the local adaptations of international codes.
Once the code data is integrated into the 3D model, BIM software applications automatically detect code violations and notify of modifications. Through model checking, architects and engineers can implement compliance tests directly within the digital model, thus minimizing the chances of manual review efforts and human error.
BIM specifically integrates rule-based systems that match project designs against pre-defined building regulations, ensuring that requirements from the International Building Code, International Residential Code (IRC), and other standards are specifically addressed before construction kicks off.
The clash detection properties of BIM would additionally curtail design conflicts that would otherwise eventually buttress the case for noncompliance. For example, BIM helps mass timber structures be resistant to fire hazards and streamlines compliance with load-bearing requirements and the latest codes. By directly embedding regulations into digital workflows, stakeholders can resolve compliance concerns, avoid rework, and costly delays.
Being able to do compliance checks earlier on is one of the main benefits of BIM. Discovering code violations before construction starts helps to avoid design modifications at the last minute or any stoppage of the project.
The proactive stance protects not just designers and contractors but also fast-track compliance checks for code enforcement officials, allowing them to render decisions more quickly and accurately.
While automated code checking is one of its orientations, BIM greatly improves the overall accuracy and adequacy of compliance documentation. All project information is compiled into a single, organized digital model, thereby easing report, drawing, and specification preparations for the regulations about a project. This aspect is vital when there are existing building systems in the picture, wherein documentation has to prove compliance with current standards.
BIM offers the possibility of on-demand reporting regarding the assessment of compliance with data extending into the required level of detail. Be it for demonstrating improved classroom acoustics in an educational facility or for fire-life safety considerations in a high-rise, BIM reports allow for the clear visualization of evidence produced that demonstrates compliance with International Code Council regulations.
The use of 3D visualizations to strengthen the reports provided can serve to improve the review of compliance by code officials with minimal manual verification.
Digital document management allows significant advantages over the traditional paper-based system. BIM ensures that all compliance-related data stays current and accessible, thus reducing the risk of discrepancies and misinterpretations.
Further, with BIM's capabilities of real-time updating, design teams can make quick modifications in response to regulatory changes. This efficiency improves approval timelines and fosters coordination between project stakeholders to ensure that international building code requirements are seamlessly infused into the project.
Project stakeholder can collaborate and come together on a single platform seamlessly with BIM. BIM also ensures that the building codes given by international code council are being effectively managed.
It actually provides for a centralized data environment, where architects, engineers, contractors, and code enforcement officials work on a single shared model, reducing instances of misunderstanding and misinterpretation of model code requirements of their construction projects.
The ability to facilitate code inspections and virtual reviews are among BIM's additional advantages. Instead of vetting designs only in the conventional context of on-site inspections, now an inspector is able to easily visualize and ascertain from a digital environment potential noncompliance early in the process stages.
This is most beneficial to projects that involve existing buildings because such buildings have undergone some changes in the laws, and verifying whether or not they comply with the updated regulations could be really tedious.
Basically, BIM enables remote access to compliance data, reduces delays, and ensures that enforcement officials receive real-time feedback about the extent of completion.
Through BIM, designers and engineers can simulate fire scenarios to analyze egress routes, thus playing an important role in ensuring compliance with fire safety regulations. By embedding model codes like International Building Code (IBC) and I-Codes, BIM allows for the assessment of fire compartmentation, fire walls, smoke control measures, and emergency exit strategies.
Designers can assess how effectively fire evacuation paths or automatic sprinkler protection work. With the corresponding simulations, BIM checks for stairwells, corridors, and exits to allow safe movement for occupants during emergencies.
Public entities in the US are currently facilitating heavy investments in modifications of existing buildings to be ADA compliant.
The renovation of The University of Wisconsin-Whitewater with a budget of $89 million, covering the retrofit of two buildings in one of the prominent instances. It includes several modifications, including accessible restrooms and modernization of elevators.
Recent allegations regarding non-compliance of buildings with ADA codes further fuel this drive. The New York Public Library is executing a $106 million retrofit of its historic branch in Manhattan, aiming to achieve complete ADA compliance.
Here, BIM plays a pivotal role in helping project teams validate the access provisions defined by the ADA (Americans with Disabilities Act) or ISO 21542.
It allows for embedding accessibility codes into the digital model to make the design of the building cater to individuals with disabilities. BIM’s impressive visualization capabilities further enhance this process through simulations. Professionals can visualize wheelchair movement through access routes, ramps at different locations, and even ensure that door clearances do not interfere with mobility.
Known for enhancing collaboration across multiple trades, BIM underpins communication with regulatory bodies.
Improper permitting processes have been the reason for significant delays in coonstruction og even single-family homes. Regarding infrastructure projects, as per the U.S. Chamber of Commerce, obtaining a federal permit takes an average of 7.7 years.
Such delays undermine critical infrastructure development in transportation, energy, and communication sectors.
BIM becomes a lifesaver, streamlining communication between regulatory bodies and project owners.
It reduces paperwork, promoting remote inspections and real-time feedback on compliance issues. An advanced process, along with direct generation of digital compliance reports from 3D models, accelerates the process in no small measure.
However, the acceptance rate and process evolution are slow, and will add a few more years to transmute into a mainstream process.
Another application of BIM in construction is using it to make a building compliant with sustainability regulations.
And this is due to the government worldwide imposing standards to achieve “net zero” goals for building. Federal Funding supporting energy efficiency projects in the United States passed a $1.2 trillion bill for allocations for energy efficiency projects across several sectors. For instance, $225 million is allocated for the country’s states to undertake modifications and train personnel to achieve net zero emissions.
Furthermore, K-12 public schools get $500 million, while for nonprofits and churches, $50 million is earmarked.
BIM plays a direct role in the modeling phase with energy modeling and performance analysis. Modelers convert the data-rich 3D model into energy models to analyse the usage across building parts. This helps optimize building facilities that consume more energy than the building produces. The goal here remains to achieve net zero emissions, where a building consumes energy equal to the amount it produces.
Such energy models are operational throughout an asset’s lifecycle, facilitating performance analysis. Real-time data from IoT sensors supports informed decisions to ensure that energy usage is optimal for every facility.
BIM accelerates the process of being compliant with green building certifications like LEED, BREEAM.
Compliance with this standard means that a building, especially educational institutions, maintains a specified acceptable levels of reverberation, sound isolation and background noise for optimal learning environments.
Codes like ANSI/ASA S12.60 control these metrics to ensure enhanced classroom acoustics for institutions in the US. With the US government mandating compliance with this standard state and federal school constructions are active towards it.
BIM plays a critical role here, by enabling designers to evaluate the sound performance of classrooms.
With the impressive data-rich modelling, the specified acoustic performance data to ensure design alignment before construction begins. When integrated with simulation tools, the acoustic performance can become predictable, facilitating further accuracy in compliance with the codes.
With the growing concerns for safety, structural integrity, and sustainability, compliance with building codes/standards governing these areas becomes mandate. While the traditional methods, result in miscommunications with regulatory bodies, unorganized paperwork, and delays in obtaining permits.
BIM redefines this whole process, by digitizing compliance report generation, integration of code/standards data for real-time model feedback on compliance, and by enabling simulation of operational scenarios. These impressive capabilities of BIM, further strengthens the compliance process, therefore adding significant value to construction projects.
If traditional method bottlenecks also hinder your project progress, contacting a BIM service provider with decades of experience, like Pinnacle Infotech, will introduce a turning point for you.
If your firm already works on a BIM-based workflow, there is no need to do anything extra. The software applications you are working on provide features for code data integration. Upon integration, the software detects code/standard violations in the model.
The ISO 19650 series of codes is the top standard in the world of BIM, which governs the management of asset data across different stages of a construction project.
While every project stakeholder should be aware of code compliance, project managers should possess detailed knowledge of the applicable building codes. It will help in effective communication with regulatory bodies and streamlining project execution as per code compliance.
