- 2. MEP Stands for “ Mechanical, Electrical and Plumbing” in the construction world. Important across all stages of the construction process. A building’s central nervous system. Make a building livable and pleasant, no matter if it’s a single storey home or a 50- storey skyscraper. 1
- 3. Components of MEP Mechanical- The mechanical design elements of a building, most especially the heating and cooling systems, help make life inside more comfortable. These systems allow us to occupy buildings in hot and cold temperature, under all weather conditions. Electrical- The electrical system in a building keeps the lights on, keeps our devices powered, and keeps the other systems running. Architectural lighting design and plans are a crucial component of the electrical engineering process. Plumbing- Water is what sustains us. Plumbing systems provide fresh water for drinking, cleaning and more. Moreover, plumbing systems are also responsible for drainage facilities such as discharge of storm and sanitary wastewater away safely. 2
- 4. Importance of MEP For planning, decision-making, accurate documentation, performance and cost estimation, construction and operating the resulting facilities. It is also required for the maintenance of the building. To maximize the long term value of the project. It analyzes and evaluates individual building systems within the overall context of the entire project. 3
- 5. Mechanical Component The mechanical component of MEP is an important superset of HVAC services. Thus, it incorporates the control of environmental factors, either for human comfort or for the operation of machines. Heating, cooling, ventilation and exhaustion are all key areas to consider in the mechanical planning of a building. In special cases, water cooling/heating, humidity control or air filtration may also be incorporated. For example, Google's data centres make extensive use of heat exchangers to cool their servers. This system creates an additional overhead of 12% of initial energy consumption. This is a vast improvement from traditional active cooling units which have an overhead of 30-70%. However, this novel and complicated method requires careful and expensive planning from mechanical engineers, who must work closely with the engineers designing the electrical and plumbing systems for a building. 4
- 6. HVAC (heating, ventilation and air conditioner) It refers to the systems that regulate and move heated and cooled air throughout residential and commercial buildings, from homes to offices to indoor stadiums. 5
- 7. WHAT IS MECHANICAL ENGINEERING ? Mechanical engineering is a branch of engineering that deals with the design, analysis, manufacturing, and maintenance of mechanical systems. It involves the use of principles of physics, materials science, and mathematics to develop and improve machines and mechanical devices Mechanical engineers design and develop a wide range of products, from small individual parts and devices, to large machines and systems. These may include engines, turbines, pumps, compressors, vehicles, robots, and manufacturing equipment. They are involved in all aspects of the product lifecycle, from conceptualization and design, to testing, production, and maintenance. 6
- 8. 1. Fire Suppression Systems :- Fire suppression systems are designed to detect and extinguish fires in buildings. They include equipment such as sprinklers, fire alarms, and fire extinguishers. 7 Some common mechanical devices used in buildings include:
- 9. 2. Generators :- Generators are mechanical devices that provide backup power to buildings in the event of a power outage. 3. Pumps :- Pumps are used to move liquids, such as water or sewage, through pipes and drainage systems in buildings. 4. Fans :- Fans are used to circulate air and improve ventilation in buildings. 8
- 10. 5. Electric Heaters :- Electric heaters use electrical resistance to generate heat. They are available in a variety of styles, including portable heaters, baseboard heaters, and wall-mounted heaters. 6. Boilers :- Boilers are a common heating system used in many homes to provide heat and hot water. They work by heating water which is then distributed through pipes to radiators, underfloor heating systems, or taps and showers. 7. Dampers :- Dampers are mechanical devices used to regulate airflow or gas flow in heating, ventilation, and air conditioning (HVAC) systems. They are designed to control the amount of air or gas that enters or leaves a space, and to maintain proper ventilation and temperature control. 9
- 11. 10 Mechanical as Building Transportation Mechanical components are also used for transportation in buildings. Some of them are listed below: 1. Lifts/Elevators: A lift(or elevator) is a form of vertical transportation between building floors or levels, commonly used in offices, public building and other types of multi-storey building. Lifts can be used in providing vertical circulation, particularly in tall buildings, for wheelchair and other non-ambulant building users and for the vertical transportation of goods. Some lifts may also be used for firefighting and evacuation purposes.
- 12. 2. Escalators: Escalators are mechanical devices used for transporting people vertically between different levels of buildings. Typically, they take the form of moving staircase. Escalators are commonly used in buildings when the movement of a large number of people is required, such as shopping centres, airports, hotels, public buildings and so on. Some basic advantages of escalators over elevators are: Generally have no waiting time(other than during periods of congestion). Allow a greater flow of people, and can be more practical. Possible for people to walk up or down by themselves if they are in a hurry. 11 A variation of the escalator is the moving walkway, which transports people horizontally.
- 13. Mechanical as Public Safety Mechanical systems are also used for public safety in buildings. They are: Evacuation Lifts: In general it is not appropriate to use the lifts when there is fire in building because there is a danger of people being trapped in a list that has been immobilized as a result of the fire. However, in some circumstances a lift maybe provided as a part of a management plan for evacuating people. In such cases the lift installation may need to be appproriately sited an protected and may need to contain a number of safety features that are intended to ensure that the lift remains usable for evacuation process during the fire. 12
- 14. Firefighting Lift: A lift designed to have additional protection, with controls that enable it to be used under the direct control of the fire and rescue service in fighting fire. A firefighting lift is required if the building has a floor more than 18m above, or more than 10m below fire service access level. Firefighting lifts have very specific safety requirements and the presence of firefighting controls within a lift does not necessarily mean that it’s a firefighting lift. 13
- 15. Inter relationship between MEP: MEP systems are closely interdependent and rely on each other to function properly. They must be designed and coordinated in a collaborative manner to ensure optimal performance. Mechanical systems, such as heating, ventilation, and air conditioning (HVAC), rely on electrical power to function. Electrical systems provide the power needed for mechanical systems to operate efficiently. Plumbing systems, such as water supply and drainage, rely on both mechanical and electrical systems. Mechanical pumps and valves are used to control the flow of water, while electrical sensors and controls are used to monitor and regulate water pressure. Plumbing systems provide the necessary water and waste removal infrastructure to support the various mechanical and electrical systems. 14
- 16. MEP systems must meet a variety of building codes and standards, including energy efficiency requirements, safety codes, and environmental regulations. MEP engineers work together to ensure that building systems are designed, constructed, and maintained to meet the needs of building occupants and operators. The inter-relationship between MEP systems is also evident in the maintenance and repair of buildings, as problems with one system can often affect the operation of other systems. 15
