YOUR INTERACTIVE MEP ENGINEERING WORKSPACE
Explore MEP systems.
Learn by doing.
Free virtual labs and engineering calculators for electrical (LV, MV and HV), HVAC, fire alarm and ELV systems. Explore HV and MV substations, switchgear checks, cable containment, FAHU operation, earthing, solar PV and more. Work through real engineering scenarios, inspect results and learn how systems behave.

10 disciplines, one workspace
Pick a discipline to jump to its labs.
240+ codes and standards referenced
Counted from the labs themselves. Each lab names the edition it follows, so you can check it against the one your authority has adopted.
International and national standards
Authority and rating scheme rules
Built for 9 regions
Switch the region inside a lab and the limits, tariffs and authority checks change with it.
4,373 questions with worked answers
Practise, revise for your licence, or let the Copilot find the answer for you.
415 real site cases
The calculation was right, but something failed on site. Each case gives what went wrong, why, the checks and the fix.
See the engineering, not just the numbers
Most labs show the same design four ways. Change an input and every view updates live.
Single line diagrams, wiring schematics, floor plans, sections and charts you can click.
Rotate switchboards, substations, plant rooms, cable trays and risers in 3D.
Watch installation, testing and energisation play out step by step over time.
See quantities turn into an indicative budget and embodied carbon as you design.
