How to select an MEP contractor — what to check, ask for and watch out for
An MEP contract is decided long before the lowest price arrives. The contractor's licence, their approvals record, who actually stamps their drawings, and whether their quotation prices the same building as the next one — these decide the outcome. This guide is the checklist a procurement team can run in a week.

What to check
- Who designs — an in-house engineering team that stamps its own drawings, or a subcontracted consultant; ask to see drawings the contractor filed in its own name
- Approvals record — which Fire NOC, CEIG and DISCOM applications the contractor has filed as applicant, in which states, in the last two years
- Comparable work — projects of similar occupancy, size and disciplines, with a client contact who can be called
- Licences — the state electrical contractor licence and supervisor certificates; without them the contractor cannot get your installation energised in its own name
- Financial capacity — audited statements or a banker's reference adequate for the contract value; the advance should not be funding their procurement
- Team on the ground — the project manager and site engineer proposed for your job, and their current commitments
- Safety record — the HSE policy, the incident record behind it, and how it is enforced on site
Documents to request
- Company registration and GSTIN matching the entity that will sign
- Electrical contractor licence and supervisor certificates (state licensing board)
- PF and ESI registrations
- ISO 9001 certificate if quality certification is claimed
- Completion or performance certificates for three comparable projects, with contact details
- A sample of the contractor's own drawings, BOQ and test report from a past project
- Audited financials or a banker's reference
Technical questions to ask
- How will you establish the design loads — heat load, electrical load list, fire hazard class, water demand — and can we see the calculation basis?
- Which approvals will you file as the applicant, and what do you need from us to file them before construction rather than after?
- How do you coordinate the ceiling void between ducts, trays, pipes and sprinkler mains before fabrication?
- What is your testing and commissioning plan, and what records will we receive?
- Which makes will you specify for the major plant, and will you name them in the contract?
Commercial questions to ask
- Lump sum or item rate — and if item rate, who carries the quantity risk?
- What is excluded — statutory fees, civil builder's work, owner-supplied items, site power and water, scaffolding?
- How are variations priced, instructed and approved?
- What is the rate validity, and is there an escalation clause for copper and steel?
- What are the payment milestones, and are they tied to stage completion certificates?
- What is the defect-liability period and what does it cover — labour only, or parts as well?
Hidden scope gaps to look for
- Approvals silent in the quotation — the bidder will raise them after award
- Testing, adjusting and balancing, and integrated commissioning absent as line items
- As-built drawings and the O&M dossier not priced
- Fire-stopping at penetrations, core cutting and sleeves left to "others"
- Equipment quoted as "reputed make" with no name
- Quantities taken from floor area rather than measured from drawings
Commissioning documentation to insist on
- Test reports with values: insulation and earth resistance by circuit and pit, hydrostatic test pressures, air and water balancing at every terminal
- Integrated cause-and-effect test record for fire, HVAC, lifts and access control
- Equipment test certificates and warranty cards, in one register
- As-built drawings for every discipline
- The approvals file — final Fire NOC, CEIG clearance, DISCOM connection, consents — with renewal dates
- O&M manuals and operator training record
Warranty and AMC terms to review
- Defect-liability period — start date, duration, response time, and whether parts are included
- Manufacturer warranties assigned to the client, not held by the contractor
- An AMC offer with a preventive schedule by asset and SLA definitions in measurable terms
- Who carries the statutory renewals — Fire NOC, CEIG periodic inspection, consents — after handover
Safety and compliance issues that matter
- Design to NBC 2016 Part 4 for fire and to the CEA safety regulations for electrical, stated in the contract
- A licensed contractor for the electrical installation — the CEIG will not accept test reports otherwise
- Permits to work, height and confined-space procedures, and toolbox records on site
- Insurance — contractor's all-risk and workmen's compensation — in force for the contract period
How Secured Engineers can help
Secured Engineers Pvt. Ltd. designs in-house, files Fire NOC, CEIG and DISCOM applications as the applicant, and delivers MEPF under one contract with the test records and handover documents listed above as standard. If you would like a quotation you already hold reviewed against this checklist, that is one of the things a technical review is for.
