M&E package QA: how to set up records that comply and protect you

Mechanical and electrical (M&E) packages are where compliance, coordination and commercial risk meet. Services pass through fire compartments, get hidden above ceilings and in risers, and are tested and commissioned at the very end, when time is shortest. Without good records, the M&E contractor is often the one left to prove it wasn’t their fault.

This guide shows how to set up QA on an M&E package so you comply and cover yourself.

Why M&E is high-risk for QA

• Penetrations: every pipe, duct and cable through a fire-rated wall or floor needs fire stopping. Who seals it, and when, is a frequent gap.
• Hidden work: risers, ceiling voids and service zones close quickly.
• Late design change: reroutes and substitutions are common, and are often undocumented.
• Testing and commissioning: certificates arrive late, yet they’re needed for handover, O&Ms and on higher-risk buildings Gateway 3.
• Disputes: damage, rework and delay claims often turn on who did what, and when.

Set up the package properly

1. Agree the ITP before you start

Write an Inspection and Test Plan for each system: containment, pipework, ductwork, electrical installation, fire alarm, sprinklers, smoke control. Include hold points for:

• First fix before ceilings and linings close
• Pressure testing of pipework before insulation or concealment
• Services complete → hand-back to fire stopping for every compartment wall and floor
• Pre-commissioning checks and final commissioning witness points

2. Control penetrations

• Keep a penetration register: ID, location, service, size, wall or floor rating, who seals it
• Photograph each penetration before and after sealing
• Get a signed hand-back when your services are complete in an area, so later damage or changes by others are clearly not yours

3. Record installation at the time

• Inspection records at each hold point, with location, drawing revision and photos
• Product data for what was actually installed, especially where substitutes were approved
• Operative competence: cards, certificates and briefings

4. Testing and commissioning evidence

• Test certificates linked to the system and location they cover
• Commissioning plans agreed early, with witness points
• Defects found in testing raised as NCRs and closed with evidence

How good records cover you

• Damage by others: dated photos and hand-back records show the condition you left work in
• Variations: records of instructed changes, reroutes and extra penetrations support your account
• Delays: inspection records show when areas were ready and when you were held up
• Payment applications: monthly QA reports evidence completed, accepted work, so valuations are harder to dispute
• Handover: records feed straight into O&M manuals and the golden thread

Do you need a full-time QA manager?

Many M&E subcontractors don’t need one on every site. A practical model is to set up the ITPs, forms and registers once, let your supervisors record day-to-day work, and call in an independent inspector at hold points, with a QA report monthly or on request. You pay for inspections, not for waiting, and you get records the main contractor and client trust.
