MEP: The Services Work in Construction, bct-7


"Experts say MEP construction involves 40% of total cost of a building construction."

How many times have you heard the term MEP in construction sector?

When I was fresher, just passed out from institute and entered into the construction profession, I heard this term many times. I couldn't understand this clearly that time.

MEP stands for Mechanical, Electrical and Plumbing. And these are the services work in construction. We defined it as the 6th work-phase in our building construction tutorial series.

Services Work in Building Construction, MEP Construction, Building Construction Tutorial


6th Work-Phase: Services Work


Following services works involve in building construction:

  • Mechanical Services
  • Electrical Services
  • Plumbing Services


Why should we know about MEP as we are civil construction person?

Well, suppose you completed the reinforcement work of a slab, now what is the next task? Pouring concrete, right?

But there are some other tasks to do before pouring concrete. Such as electrical conduit laying in slab, placing duct for plumbing and electrical services, etc.

As we know, one task is dependent on another task in civil construction, So services works interfere in civil works. 
That's why we should have some basic knowledge about MEP. So that we can understand dependency of tasks.

In this post we'll see which MEP tasks involve in building construction.

MEP Tasks Involve in Building Construction

Mechanical Services work: Mechanical services work performs following task in building construction -

  • HVAC (Heating, ventilation and Air conditioning system)
  • Gas supply system
  • Fire Fighting system
  • Elevators and Escalators work


Electrical Services work: Electrical work begins even before starting actual building construction. That is, it involves from temporary electrical connection in mobilization-phase until finishing of the project.

Electrical services work performs following tasks in building construction -


  • Power Supply
  • Cable TV System
  • Fire Alarm System
  • Security System
  • Telephone and Data network System
  • Emergency Power Supply System (such as IPS: battery-backed power Supply )
  • Backup Power System (Such as Generator)

Plumbing Services: In a simple word, plumbing services performs supplying water and removing waste water in a scientific way in building.

From the above statement we found two tasks which done by plumbing services.

There are also some other tasks performed by plumbing services to support above two task.

We can list them all as following -


  • Water Supply System
  • Drainage System
  • Rain Water Harvesting
  • Water Treatment Plant
  • Water Recycling System

MEP services may do many other tasks. But some task are not related to our building construction. So I didn't include them here.

Did I miss anything here? Please leave a reply in comment section below.
