Smart strategies support integrated MEP retrofitting in existing buildings

Ar. Shivang Bansal explains the complexities of upgrading MEP systems in existing buildings, emphasising the potential of BIM, modular components, and smart technologies to optimise space, improve fire safety, and future-proof high-rise infrastructure.

What are the challenges associated with retrofitting MEP systems in existing buildings, and what are the best methods to overcome them?
Retrofitting MEP systems in existing buildings presents a unique set of challenges, including restricted space, antiquated infrastructure, and incomplete documentation of current services. One of the most pressing concerns is integrating new technology without disturbing existing operations or jeopardising structural integrity. Our approach begins with a thorough site audit, supplemented by point cloud-based digital surveys and image-based models. These tools enable us to recreate the original building conditions within a BIM platform accurately. Once we have a full digital representation, we determine retrofitting requirements and plan the workflow and design integration accordingly. We prioritise multilayer collaboration among architectural, structural, and service components to guarantee that the retrofit is less invasive and scalable. Wherever practical, we use modular MEP components and prefabricated systems to decrease on-site labour and installation time.

What strategies do you employ to optimise space utilisation and MEP system integration?
Efficient space utilisation is the foundation of sustainable, cost-effective design. Our technique is based on early-stage MEP coordination, where architecture and services are developed concurrently rather than sequentially. We extensively utilise BIM to identify clashes and visualise spatial implications during schematic design. In high-density buildings, we prioritise vertical zoning, which involves optimising shaft placements, service corridors, and ceiling spaces. Ducts, conduits, and plumbing stacks are intelligently routed to minimise confrontation with architectural or structural aspects. Furthermore, we design for future adaptability by allocating service zones that can evolve to meet changing building needs, decreasing the long-term upgrade burden.

How do you approach the design and implementation of fire protection systems for high-rise buildings?
Fire safety in high-rise structures is unavoidably and fundamentally complicated due to vertical scale, evacuation issues, and pressure zoning. Our fire protection design is always integrated with life safety and structural systems from the start. We implement a performance-based strategy that extends beyond code compliance. Automatic sprinkler networks, pressurised stairwells, fire-rated shafts, and sophisticated detection systems are all designed in combination with the architectural form. Special emphasis is placed on material selection, vertical service core planning, and emergency access strategies. We also work closely with fire consultants and local authorities to ensure that safety measures align with evolving regulatory frameworks and site-specific risks.

How can technology be leveraged to enhance MEP services and performance in high-rise buildings and commercial structures?
Technology is now a facilitator of performance, accuracy, and sustainability rather than an add-on. We incorporate modern tools and digital workflows into all stages of MEP design and execution. From BIM-based coordination and simulation to IoT-enabled building management systems (BMS), we design infrastructure that is responsive, energy-efficient, and easy to maintain. Our specs include technologies such as variable frequency drives (VFDs), smart HVAC controls, automatic lighting, and water reuse systems. Furthermore, data-driven commissioning and real-time monitoring provide predictive maintenance and lifespan optimisation. By integrating MEP design with smart technology, we ensure that high-rise and commercial buildings operate reliably while decreasing environmental impact and operational expenses.
