MEP internship online: what you learn and what you can show

An MEP internship online should teach you how a building is served: cooled, drained, protected from fire and powered. It should also leave you with calculations and documents you can explain. Ours covers 8 learning weeks, the first 4 are the Free internship, and each week has a hand-in. This post gives the real week titles and what each one produces.

One fact about our own programme, so you can judge everything here fairly. The EDWartens internships are a training programme, not employment. The Free internship is 4 weeks, online and self-paced, with all four weeks open on day 1. It has lesson cards and a weekly check. You also work in the Virtual Workplace, a simulated plant or office with AI colleagues, and AI marks your hand-ins. There is no stipend, and we do not promise a job, an interview or a placement.

Week 1: What MEP is and how a building project runs

You learn the MEP trades, the stages of a building project and who does what. You also learn a rule that decides many arguments on site: why the drain gets the ceiling space first. Falls cannot be changed, but ducts and cable trays can be moved. The week ends with a short check.

Week 2: HVAC basics: loads, air and water

You trace the heat path of a cooled building and estimate a cooling load in kW and TR. You then turn the load into airflow, water flow and fresh air. The point is the chain from load to flow, because every later choice, from duct size to pump, depends on it. The hand-in is a short cooling load sheet. Standards bodies such as ASHRAE publish the reference methods used in practice.

Week 3: Plumbing and drainage basics

You name the plumbing systems and size a supply pipe from flow and velocity. You keep hot water safe from Legionella and set drain falls and a roof drain flow. The week is practical and numerical, with clear answers you can check.

Week 4: Fire fighting and sprinklers

You name the fire fighting water systems and sprinkler types and read a hazard class. You work out a design flow and tank volume, and say what a fire pump must deliver. This is the last week of the Free internship, after which you sit the final exam. Fire codes differ by country, and bodies such as NFPA publish widely used ones, so always check the code that applies where you work.

Weeks 5 to 8, if you extend

These weeks open when you extend the Free internship by 4 weeks (paid), or in the Engineer-verified edition, where an engineer also reviews your work.

• Week 5: Fire alarm and ELV systems. You describe how a fire alarm works, place detectors, size a standby battery, read a cause and effect matrix and name the main ELV systems.
• Week 6: Electrical services in buildings. You follow power from the utility to a socket, turn connected load into maximum demand and a transformer size, size a final circuit and explain standby power and lighting levels.
• Week 7: BIM and coordination (clash detection, ISO 19650 basics). You explain a federated model, the roles and documents of ISO 19650, the four states of a common data environment, and how clashes are found, reported and settled.
• Week 8: Testing, commissioning and handover of building services. You describe the commissioning levels, pass or fail typical pressure, balancing and electrical results, list the fire and life safety tests, and name what goes in a handover pack.

What do you hand in?

Each week a simulated colleague in the Virtual Workplace sends a brief for a made-up clinic building. You answer with a calculation sheet or a short document. In the free weeks, that is a services map for the clinic, a cooling load sheet for a meeting room, a plumbing and drainage sheet, and a sprinkler demand note for a basement car park. AI marks the hand-ins and says what to fix.

What can you show afterwards?

A verified record and a few pieces of work you can explain. The free certificate has your real dates and active hours and a QR code. The pieces are your own calculations. Describe them as training work, and be ready to say how you got each number, because that is what a hiring manager or lecturer will ask. Do not describe the internship as site experience.

How does the exam work?

The Free internship ends with a final exam of 15 multiple-choice questions. You have 60 minutes, you pass at 60%, and it opens full screen and is marked automatically. You get 3 tries; after that a fresh paper opens 24 hours later. When you pass, you can claim the free certificate. It shows your real start and finish dates and your active hours, and it carries a QR code so anyone can verify it. How the certificates work explains what each one shows.

If you want a person to look at your work, the paid Engineer-verified edition runs for 4 or 8 weeks. An engineer reviews what you hand in, and the documents are signed by Brijin Chacko. Details and prices, shown in your own currency, are on the Engineer-verified page.

Which free courses go deeper?

Our free courses on HVAC design: heat load, ducts and chilled water, plumbing and drainage design for buildings, fire fighting, sprinklers and fire pump design and BIM coordination, ISO 19650 and clash detection match the first weeks closely. ISO publishes the ISO 19650 series on managing information with BIM.
