BIM & Safety

Introduction

Building Information Modelling, or BIM, is no longer a novelty in the construction realm. But beyond its capabilities for design and engineering, BIM has paved the way for enhanced safety protocols. In this article, we will delve into how BIM is setting new safety standards in construction.

The Historical Safety Lens

Before computer-aided design, safety relied on the experience and intuition of veteran builders. Mistakes, often, were costly. As technology progressed, tools like AutoCAD offered more precision. But BIM takes this several notches higher by adding time and cost dimensions.

The Building Safety Act: A New Era for Construction Safety

The construction industry, though inherently laden with risks, has significantly evolved in its approach to safety. This evolution is punctuated by critical legislation aimed at improving standards and ensuring that the well-being of occupants is paramount. A cornerstone in recent legislative efforts is the Building Safety Act [1, 2].

What is the Building Safety Act? The Building Safety Act is a piece of legislation introduced to bolster the safety of people in and around buildings, particularly those residing in high-rise residential buildings. This act was conceived in the wake of tragic incidents where building safety lapses led to catastrophic outcomes. The most notable among these is the Grenfell Tower fire in London in 2017. The tragedy underscored the pressing need to overhaul building safety regulations.

Key Provisions of the Building Safety Act:

• Accountability and Duty Holders: One of the act's hallmarks is the clear delineation of responsibility. It establishes 'duty holders' during the design, construction, and occupation phases, ensuring that there is a clear line of accountability throughout a building's lifecycle.
• Building Safety Regulator: The act institutes a national Building Safety Regulator, responsible for overseeing the safety and standard of all buildings. This independent body ensures that regulations are adhered to and provides a centralised authority on building safety matters.
• Residents' Voice: Ensuring that residents have a say in their safety, the act mandates a more transparent system where residents can access safety information about their dwellings. Moreover, it provides avenues for residents to raise concerns about building safety, ensuring they are active stakeholders.
• Higher Risk Buildings: The act pays particular attention to buildings classified as 'higher risk', such as high-rise residential structures. Such buildings will be subjected to additional safety measures, regular assessments, and stringent safety standards to ensure the well-being of the occupants.

Implications for the Construction Industry: The Building Safety Act is not just another piece of legislation; it is a call to action. It underscores the need for a radical shift in the industry’s approach to safety. This shift is not limited to design or materials used but extends to an all-encompassing approach that places residents at the heart of all safety considerations.

For those in the construction realm, this act implies:

• Enhanced Scrutiny: From design to construction, each phase will now be under the lens, requiring professionals to adopt a meticulous approach.
• Increased Collaboration: The act mandates greater collaboration between various stakeholders, from architects and engineers to contractors and site managers. This cohesive approach ensures that safety considerations are consistent throughout the building's lifecycle.
• Emphasis on Documentation: With clear lines of accountability, there will be a heightened focus on documentation. Every safety measure, every material choice, and every design alteration will need to be thoroughly documented, ensuring transparency.

Conclusion

The Building Safety Act is a testament to the industry's commitment to rectify past oversights and build a future where every resident feels safe in their dwelling. For construction professionals, it emphasizes the cardinal rule that buildings are not just structures of brick and mortar but homes that house hopes, dreams, and lives. Ensuring their safety is not just a professional obligation but a moral one.

Why BIM is a Game-Changer for Safety

• Early Risk Identification: Before a single brick is laid, BIM allows professionals to identify potential risks. Whether it is an awkward turn that could cause mishaps or a potential fire hazard due to close-proximity wiring, BIM tools can flag these issues in the design phase.
• Safety Training: Forget rudimentary site walks. BIM offers virtual site walks that give workers a genuine feel of the environment, educating them about potential hazards and how to tackle them.
