MEP Budget Band Estimator: engineer's guide
MEP construction cost varies by building type, region, and specification level. Budget-band estimates give an early-stage cost envelope by trade.

What this calculator does
The calculator returns per-m² cost ranges for HVAC, electrical, plumbing, fire, and ELV based on building type and specification tier.
Formulas used
- Total MEP cost:
CMEP = A × Σ ctrade - Cost per trade:
ctrade = A × unit rate ($/m² per trade)
Variables
- A = gross floor area, m²
- Unit rates vary by region 30 to 100%
Worked example
Scenario: 5000 m² commercial office building, mid-spec, GCC.
- HVAC: $180-220/m² → $900k-1.1M
- Electrical: $120-160/m² → $600k-800k
- Plumbing: $60-90/m² → $300k-450k
- Fire: $40-60/m² → $200k-300k
- ELV: $60-90/m² → $300k-450k
- Total range $2.3M to $3.1M
Common mistakes to avoid
- Applying office rates to hospital (2-3x higher)
- Missing site infrastructure (chiller plant, substation)
- No allowance for premium finishes on ELV
- Ignoring escalation for long-programme projects
Frequently asked questions
What tier is "mid-spec"?
Standard commercial grade — VRF or chilled water, LED, standard fire alarm, moderate ELV.
When to move to detailed BOQ?
After schematic design when major equipment counts are firm.
