MEP Quantities: High-Level Overview for BOQ & Estimating
Mechanical, electrical, and plumbing quantities at a summary level—where BOQ splits and coordination matter.
How MEP splits
MEP BOQs may separate supply, install, testing, commissioning, and attendances. Equipment tags on drawings should match spec sections you price.
Coordination with fire protection, IT, and security prevents duplicated allowances.
Duct and pipe runs may be measured linear with fittings counted separately—confirm whether fittings are “extra over” or included.
Discipline boundaries
LV vs ELV, BMS, and specialist systems often blur—use the responsibility matrix to decide what sits in your package.
Builder’s work for openings, sleeves, and pads is frequently measured in civil/structural BOQ—coordinate before you assume MEP includes coring.
Testing, commissioning, and O&M
Balancing, flushing, pressure tests, and witness tests may be priced as lump sums or per system.
O&M manuals and as-built drawings are sometimes a prelim allowance—check who produces them and when.
