PERFORMANCE BASED APPROACH (PBA)

Introduction

The Fire Engineering-Performance Based Approach (PBA) is a system for designing, evaluating, and assessing building fire safety. To meet the goals of BS 7974:2019- Application of Fire Safety Engineering Concepts to Building Design, the design relies on the use of fire engineering principles, calculations, and appropriate software modelling tools.

Any purpose group utilised for bulk storage or processing of flammable liquids, industrial chemicals, or explosive materials is not covered by the PBA. The risk involved of such structures will require careful consideration. In Malaysia, it is necessary to adhere to all provisions of the prescriptive building codes of the Uniform Building By-Law (UBBL) 1984 (amendment 2012) and Sarawak Building Ordinance 1994 (amendment 2008), although it is permissible to utilise the PBA approach in the event of noncompliance.

Noncompliance allowed only for compartmentation and travel distance during architectural plan approval if the project’s development exceeds 150 metres in height and covers an area of more than one million square metres. As well as mixed development, where such purpose groups find it difficult to meet the common compartmentation needs.

Computational Fluid Dynamics (CFD) was used to design a smoke management system

The main concept of the PBA is smoke control with proper evacuation, with consultants expected to pay close attention to the exact perimeters used to represent the situation. And, especially when it comes to simulation, calculation, and documentation, it is critical to verify the perimeter proposed accurately and precisely.

 The Fire Safety Consultant’s duty and responsibility is to provide an engineering smoke control system using Computational Fluid Dynamics (CFD) or other equivalent software for modelling purposes, as well as an evacuation study (egress).

 The Fire Safety Consultant will need to demonstrate to the Authority Having Jurisdiction (AHJ), which are FRDM representatives, that the proposed solution will fully meet the intent of the Fire Code using established fire safety engineering methodology, and that the larger compartment area will not adversely affect critical life safety tenability criteria for anticipated fire loads at compartment area during fire conditions, and that occupants will have safe egress.

OUR SCOPE OF WORK

We provide you with the latest performance-based design solutions and engineering best practices while helping to determine applicable codes and standards. We comply with the national codes and standards, engineering best practices, performance-based consulting, and fire & life safety audit criteria. Our team also specializes in construction and system investigation during the lifecycle of a building and assists in designing a go-forward plan and helps manage the upgrade.
