Mechanical
Mechanical systems are a crucial component of MEP design and engineering. HVAC systems comprise a significant part of these systems, including piping, dampers, controllers, ductwork fabrication, thermal insulation, and machines like diffusers, chiller units, and air handling units.
​
Mechanical systems are found in various commercial, industrial, and residential buildings. They can be related to transportation systems like escalators, lifts, industrial plants, and machinery. However, in commercial projects, three types of mechanical systems account for most design work: mechanical ventilation, space heating, and air conditioning.
​
These three systems work together to maintain a comfortable indoor environment by regulating humidity and temperature. Mechanical ventilation ensures fresh air is adequately supplied to the building to keep pollutants safe and low concentration. Therefore, it is essential to ensure that mechanical installations have enough capacity to operate effectively.
​
However, over-engineering mechanical systems can cause various issues. For example, oversized boilers and chillers can cycle rapidly, leading to equipment degradation and creating temperature fluctuations in the room. Additionally, over-engineering can lead to poor indoor relative humidity control, which can irritate the skin and promote bacteria and algae growth.
​
Mechanical systems are a critical component of MEP design and engineering. While they play a crucial role in maintaining a comfortable indoor environment, it is vital to ensure they are not over-engineered to avoid potential issues.

Electrical
Electrical engineering encompasses more than just the basics of electrical power and lighting. There are a variety of other critical electrical systems that are vital to the operation and safety of modern buildings.
These include emergency power, data and voice communication, security systems, television and entertainment systems, transformer substations, fire alarm systems, surge protection, access control, and lightning protection systems.
​
These various systems can be categorised into six main categories: control systems, power supply and distribution, security and access, interior and exterior lighting, information and telecommunication systems, and detection and alarm systems.
​
One of the biggest challenges electrical engineers face when designing systems for high-rise buildings is figuring out the most effective routes for wiring and conduits. However, electrical systems are more flexible than mechanical systems, as they require much less space and can be installed around obstacles with relative ease.
​
To aid in the design process, MEP (mechanical, electrical, and plumbing) design software can lay out wiring and conduits to minimise conflicts with other systems and minimise the total length of circuits. In addition, lighting systems can be simulated using these programs to determine the optimal locations and several fixtures required for a particular project.
​
It is important to note that mechanical and electrical systems often overlap, which is why the term Mechanical and Electrical (M&E) design is commonly used. In particular, HVAC (heating, ventilation, and air conditioning) design requires close collaboration between mechanical and electrical engineers during the MEP design phase. For example, electrical engineers must design protective measures and electrical circuits that enable the MEP system to operate safely and continuously. Meanwhile, mechanical engineers must calculate the cooling and heating loads of automated systems to determine the optimal capacities of the equipment. These engineers can create efficient, effective, and safe MEP systems for modern buildings by working together.

Plumbing
Plumbing systems are an essential component of any building, allowing for the movement of fluids throughout the structure. These systems comprise various interconnected parts, including pipes, tanks, plumbing fixtures, valves, and more. Much like the mechanical and electrical systems within a building, plumbing works involve the complex layout of pipeworks. Engineering firms often rely on MEP design computer programs to simplify this process.
​
The scope of plumbing works is vast and includes installing and maintaining cooling and heating systems, fuel gas piping, water recovery and treatment systems, waste removal systems, cold and hot water supply systems, and surface and rainwater drainage. Each of these systems is critical to the proper functioning of a building, and their proper installation is essential.
​
An important point to note about plumbing systems is that they frequently interact with other mechanical and electrical systems within the building. For instance, high-rise buildings often require water booster pumps powered by electricity. Similarly, domestic hot water systems require a dedicated boiler, electric heater, or heater exchange connected to a boiler.
These interactions demonstrate the importance of collaboration between design teams when creating an MEP design for a building project.
​
Plumbing systems are an integral part of building design and construction. They are complex systems that require careful planning and execution to ensure proper function and maintenance. Therefore, understanding the scope of plumbing works, including their interactions with other building systems, is essential to creating a safe and functional building.
