Choosing the wrong PEB contractor or industrial shed builder can cost you lakhs of rupees, months of delay, and endless headaches. Gujarat has hundreds of contractors claiming to be "the best" — but how do you verify who is genuinely qualified and trustworthy? This 10-point checklist will help you make the right decision before signing any contract.

💡 Key Takeaway

Never select a PEB contractor based on price alone. A vendor quoting 10–15% lower than market rate often cuts corners on steel grade, fabrication quality, or civil work — leading to structural issues within 3–5 years. Verify credentials first, negotiate price second.

The 10-Point Contractor Verification Checklist

  • 1
    Verify GST Registration & Business Incorporation
    Any legitimate PEB contractor must be GST-registered. Ask for their GSTIN and verify it on the GST portal (gst.gov.in). Also confirm they are a registered company/LLP/partnership — not just an individual freelancer for a project of your scale.
  • 2
    Check Years of Experience in PEB Specifically
    General construction experience is different from PEB/steel structure experience. Ask how many years they have been doing specifically pre-engineered buildings. Minimum 5 years for medium projects (5,000–20,000 sq ft), minimum 8–10 years for large projects. Check their first PEB project year.
  • 3
    Request a Portfolio of Completed Projects
    Ask for photos and client references of at least 5–10 completed PEB projects similar to yours in size and type. Ideally, visit one of their recent projects in person. Look for clean welds, proper paint finish, and aligned columns as indicators of fabrication quality.
  • 4
    Verify Their Own Fabrication Facility
    Does the contractor have their own fabrication workshop, or do they outsource fabrication? Companies with in-house fabrication have better quality control, faster delivery, and lower costs. Ask for the address and size of their factory. Visit if possible.
  • 5
    Ask About Steel Grade & Source
    Reputable PEB contractors use IS:2062 Grade E250/E350 structural steel from SAIL, TATA, JSW, or RINL. Reject any contractor who cannot specify the steel grade they will use or refuses to name their primary steel supplier. This is non-negotiable.
  • 6
    Confirm They Provide Structural Design & Drawings
    A proper PEB project starts with certified structural design drawings (IS:800 compliance). Ask if their design is done in-house or by a certified structural engineer. You should receive shop drawings, erection drawings, and anchor bolt plans before fabrication begins.
  • 7
    Check for Warranty on Structure and Roofing
    Standard PEB structures should come with a minimum 10-year structural warranty and 10–15 year roofing sheet warranty (against perforation, corrosion). Ask for this in writing. Contractors who refuse to give a written warranty are a red flag.
  • 8
    Verify Client References (Actually Call Them)
    Don't just take the reference list — actually call 2–3 of their previous clients. Ask: Was the project delivered on time? Were there cost overruns? How was the quality? Would you use them again? This 10-minute call can save you months of regret.
  • 9
    Clarify What's Included in the Quote (Scope of Work)
    Get a detailed bill of quantities (BOQ) with the quote. Confirm whether the quote includes: foundation/civil work, flooring, electrical provisions, ventilators, gutters and downpipes, painting (how many coats), and erection supervision. Many disputes arise from scope mismatches.
  • 10
    Review the Payment Terms and Penalty Clauses
    Legitimate contractors work with milestone-based payments — typically 30% advance, 40% on delivery of material to site, 20% during erection, 10% on completion. Avoid contractors demanding 50%+ upfront. Ensure the contract includes a penalty clause for delays beyond 30 days.

Red Flags to Avoid When Hiring a PEB Contractor

⚠️ Watch Out for These Red Flags
  • Cannot provide GST number or company registration documents
  • Quotes significantly lower than 3–4 other vendors (by 20%+) without explanation
  • No physical factory or fabrication yard — outsources everything
  • Cannot specify steel grade or name their steel supplier
  • Refuses to provide structural drawings before project start
  • No written warranty on structure or roofing
  • Demands more than 50% payment before material delivery
  • Cannot provide references from projects completed in last 2 years
  • Uses verbal agreements instead of written contracts
  • Delays providing a detailed BOQ and scope of work

Questions to Ask Before Signing the Contract

  1. What is your current order backlog and when can you start my project? — A busy contractor may push your project start by 2–3 months.
  2. Who is the site supervisor for my project? — Confirm the name and experience of the person who will be on your site daily.
  3. What is the timeline from order confirmation to project handover? — Get a phased timeline in writing.
  4. Is your quote fixed-price or subject to steel price escalation? — Price escalation clauses can increase costs by 10–15% if steel prices rise.
  5. Do you handle municipal/GIDC construction permissions? — Who is responsible for obtaining NOCs and building approvals?
