I oversee project design strategies, client coordination, and provide technical leadership for HVAC, plumbing, firefighting, and specialized systems. Additionally, I ensure effective coordination with multidisciplinary teams, maintain design quality, mentor engineers, and support the successful delivery of projects from concept through construction.
TELL US ABOUT YOUR FIRST ENGINEERING DESIGN PROJECT.
WS: One of my first independent design projects was the 100-bed Medicare Hospital, a brownfield healthcare facility. It was a highly challenging project because the existing building had very limited floor-to-floor height, making the routing and coordination of HVAC ductwork extremely difficult. This was particularly critical for sensitive areas such as operation theatres, ICUs, and other healthcare spaces where strict environmental control and compliance with healthcare standards were essential.
The project demanded innovative engineering solutions, meticulous coordination with other building services, and careful optimization of every available space. Despite these constraints, we successfully developed and implemented an efficient and reliable HVAC design that met the project’s functional requirements. Alhamdulillah, the hospital’s mechanical systems have been operating successfully for more than a decade, which remains one of the most rewarding validations of the quality and durability of our design.
TO WHAT DEGREE DOES A MECHANICAL ENGINEER CONTRIBUTE TO BUILDING DESIGN?
WS: Mechanical engineers play a critical role in modern building design, particularly in complex, high-rise, healthcare, industrial, and other high-tech projects, where mechanical systems can account for 20% or more of the overall building design scope and cost. Our responsibilities extend beyond designing HVAC, plumbing, firefighting, and specialized systems such as medical gas networks. We work closely with architects, structural engineers, and other stakeholders from the earliest design stages to ensure that all building services are fully integrated.
In addition to system design, we provide essential input for spatial planning, including the allocation of shafts, plant rooms, equipment spaces, water storage tanks, and service routes. We also develop energy-efficient and sustainable solutions that optimize building performance, reduce operational costs, and enhance occupant comfort while ensuring compliance with relevant codes and international standards.
WHAT SKILLS SHOULD A MECHANICAL ENGINEER POSSESS?
WS: In addition to strong technical expertise, a mechanical engineer working in MEP design must possess a comprehensive understanding of other engineering disciplines, including electrical, public health, structural, and architectural systems. It is essential to understand the design intent, coordination requirements, and practical limitations of each discipline to develop fully integrated and efficient building services. Since MEP systems are closely interconnected, successful designs depend on effective interdisciplinary collaboration and coordination from the conceptual stage through project completion.
Equally important are strong visualization and spatial coordination skills. A mechanical engineer should be able to mentally translate two-dimensional drawings and BIM models into real-world site conditions, anticipating how various systems will interact during construction. This ability helps identify potential clashes, optimize routing for ducts, pipes, and equipment, and ensure sufficient space for installation, maintenance, and future accessibility. By addressing coordination issues during the design phase, engineers can significantly reduce site modifications, avoid costly delays, improve construction efficiency, and deliver practical, sustainable, and high-performing MEP solutions that meet both client expectations and project requirements.
WHAT IS SUSTAINABLE DESIGN AND WHY IS IT IMPORTANT?
WS: Sustainable design focuses on developing buildings, systems, and infrastructure that minimize environmental and social impacts while efficiently utilizing natural resources. It aims to meet present-day needs without compromising the ability of future generations to meet their own. This approach goes beyond energy efficiency by considering the entire lifecycle of a building, including material selection, water management, indoor environmental quality, operational performance, and long-term resilience.
Over the past few decades, rapid urbanization and infrastructure development have often prioritized economic growth over environmental protection and social well-being. As a result, we are now witnessing the consequences in the form of climate change, rising energy consumption, resource depletion, pollution, biodiversity loss, and increasing public health concerns. These challenges have highlighted the urgent need to rethink the way we plan, design, construct, and operate our built environment.
Sustainable engineering addresses these issues by integrating energy-efficient technologies, renewable energy solutions, responsible water management, waste reduction strategies, and environmentally conscious design practices into every stage of a project. It also encourages collaboration among architects, engineers, planners, and stakeholders to create buildings that are not only environmentally responsible but also economically viable and socially beneficial.
Ultimately, sustainable engineering is about creating resilient, efficient, and future-ready developments that reduce carbon emissions, conserve natural resources, enhance occupant health and comfort, and contribute to healthier communities. By balancing environmental responsibility with economic and social considerations, it plays a critical role in achieving long-term sustainability and improving the quality of life for present and future generations.
