When you think about MEP system design, Codes and Standards are those things that will come to your mind immediately. And you will loose your track easily. Here we are to guide you to right track while MEP systems design.

Make your Check List

First of all you have to note down the utilities you are going to use in your facility.

Make a check list of MEP system requirement. Typically following systems will be integrated into your MEP system architecture.

MECHANICAL:

1. HVAC System.
2. Water Supply System (Process water)/ with or without WTP
3. Water Supply System (Utility water)./ with or without WTP
4. Steam Supply System.
5. Compressed air supply system.
6. Gas (Nitrogen, oxygen etc.) supply system.
7. Other Liquid Chemical Supply System.
8. Fuel (gas/ liquid) supply system.
9. Storage Tank for liquid/gas.
10. Material handling and storage system.

ELECTRICAL:

1. Electrical power generation system.
2. Electrical power transmission system.
3. Electrical Line distribution system.
4. Lighting system.
5. Electrical Outlet system.
6. Data communication system.
7. Fire detection system.
8. Gas detection system.
9. BMS (Building Management System).
10. Access control system.

PLUMBING:

1. Sanitary Plumbing.
2. Drainage system (including ETP).

FIRE FIGHTING SYSTEM:

1. Fire Hydrant and sprinkler system.

WTP=Water Treatment Plant.

ETP=Effluent Treatment Plant.

MEP System Architecture

Any MEP system consists of five components. Such as Generation, Storage, Distribution, Usage and Waste management. You have to integrate all these components to build a MEP system. Now you have to integrate all MEP systems to design MEP System Architecture for your facility. This may be only a conceptual design that depicts your system requirement.

MEP System Design

After conceptual design is in place, do your calculations and use design codes and safety codes associated with required system to design your MEP system.

THE CODES AND STANDARDS:

Local Design Code

BNBC: Bangladesh National Building Code. (General Code, Practiced in Bangladesh)

RAJUK Imarat Nirman Bidhimala (Required only if your facility is under RAJUK area).

Local Safety Code

NFSA: National Fire Safety Audience (Local fire safety code).

International Design Code:

ASHREA: HVAC system design.

ICE: Electrical system design code.

APA: American Plumbing Association.

ASME: American Society of Mechanical Engineering.

API: Storage Tank design code.

International Safety Code:

NFPA: fire safety code.

NFPA70: Electrical fire safety code.
