Mechanical & Electrical(M&E)
The mechanical, electrical and HVAC building-services scope of a project - heating, ventilation, power, plumbing and controls - usually one of the largest trade packages.
Mechanical and electrical (M&E) covers the systems that make a building work: heating, ventilation and air conditioning (HVAC), electrical power and lighting, plumbing and drainage, fire and life-safety systems, and building controls. On commercial, healthcare and data-centre projects M&E can be a very large share of the build cost. It is normally procured as its own package, often before the finishes trades.
For M&E contractors and building-services suppliers, catching a project while the services package is still being priced is the difference between quoting and chasing. Sector and building type are strong predictors of how heavy the M&E scope will be.
PlanningLeads flags the building type and sector behind each lead, and models the trade windows on commenced sites so you can see roughly when the M&E package is likely to be procured - at organisation and area level.

Common questions
Heating, ventilation and air conditioning (HVAC), electrical power and lighting, plumbing and drainage, fire and life-safety systems and building management controls.
Usually after the main contractor is appointed and the structure is under way, but before the final finishes - the exact timing depends on the build programme.
Data centres, pharma and life-science facilities, hospitals and large commercial buildings tend to carry the heaviest mechanical and electrical content.
