An industrial turnkey project is one contract in which a single contractor designs, builds and hands over your factory ready to operate. In Ahmedabad, the right contractor is the one whose written scope covers design, steel, civil work, utilities and the Gujarat approvals your unit needs, not the one quoting the lowest rate per square foot.
This guide is general information, not legal or engineering advice. Confirm approvals with the relevant authority and have a structural engineer review your design.
What is an industrial turnkey project?
An industrial turnkey project is a delivery model where one contractor takes responsibility for every phase needed to bring a factory into operation: design, construction, installation and commissioning under a single contract. You receive a ready-to-use facility instead of coordinating separate designers, fabricators and civil contractors.
The word comes from construction: the job is finished when the owner can simply turn the key. Mecalux describes the model as one provider handling the entire scope from start to finish.
Turnkey is often confused with other contract types. Here is how they differ:
| Turnkey / EPC (fixed price) | Lump-sum supply and build | Item-rate (measure and pay) | |
| Who provides the design | Contractor | Mostly the owner | Owner |
| How price is set | One fixed price for a defined scope | Fixed price for a defined build | Agreed rate per item × measured quantity |
| Where design and quantity risk sits | Mainly with the contractor | Shared | Mainly with the owner |
| Best fit | Complex projects where one party should own the outcome | Clear scope, defined deliverables | Work with uncertain quantities |
Source for definitions: Global Law Experts, EPC and construction contracts in India. The “where risk sits” row is our plain-English summary of those definitions.
One nuance: IMARC Engineering notes that EPC is a contract structure, while turnkey is a delivery obligation. Read the contract’s definition of “completion,” because that is where the two terms diverge in practice.
What should an industrial turnkey contract include?
A factory turnkey contract should list in writing what is covered from design to handover: engineering and drawings, foundations and civil work, the PEB or steel frame, roofing and cladding, flooring, utilities, fire safety and handover documents. Anything not listed is an exclusion you may end up paying for later.
Use this checklist when reading a quotation:
- Design basis, drawings and structural calculations
- Foundation and civil work (who designs it, who builds it)
- Steel frame, roofing, cladding and ventilation
- Flooring, mezzanine, docks and crane provisions, where needed
- Electrical, water, drainage and lighting
- Fire detection and safety systems
- Statutory approval support (see below)
- Handover documents and a defects period
Why “per sq ft” quotes mislead. The same rate can mean three different things. Tata nexarc advises asking whether a rate covers steel only, a shed-ready building, or a fully operational facility.
| Scope layer | What it typically adds |
| 1. Steel only | Frame, cladding, roofing and basic fittings |
| 2. Shed-ready | Civil work, foundations, flooring, basic utilities, compliance items |
| 3. Operational facility | Mezzanine, crane runway, insulation and other items specific to your process |
Illustrative example, not market data: Contractor A quotes a low rate that covers layer 1 only. Contractor B quotes a higher rate covering layers 1 and 2. B may be cheaper once A’s foundation and flooring are added. The only fair comparison is line by line, on the same covered area.
How much does industrial shed construction cost?
There is no single price for industrial shed construction, because published per-square-foot rates describe different scopes. One 2026 vendor guide quotes ₹1,200–₹2,600 per sq ft for complete PEB sheds, while another puts frame, cladding and roofing alone at roughly ₹300–₹600. Compare quotes by scope, not headline rate.
Sources: Construction Estimator India and Saman Portable. Both are vendor-published and not independently verified. We did not find a reliable published rate specific to Ahmedabad, so ask for a site-specific bill of quantities (BOQ).
What moves the number:
- Clear span. A wider column-free span needs heavier members, so steel weight per sq ft rises (Saman Portable).
- Eave height and bay spacing. These also change steel weight (Tata nexarc).
- Foundation and civil work. First-time buyers are often surprised by this part (Tata nexarc).
- Add-ons. Insulation, mezzanines and crane support.
How to compare two quotes (5 steps):
- Convert both to the same covered area and clear height.
- List inclusions and exclusions side by side.
- Ask for the steel tonnage and design basis behind each rate.
- Check who prices the foundation and flooring.
- Check payment milestones against physical progress.
Which approvals does a factory need in Gujarat?
A new factory in Gujarat generally needs an approved building plan, factory plan approval under the Factories Act, a fire NOC and, for applicable industries, pollution-board consent before the factory licence is granted. The exact sequence depends on your plot (GIDC or other), your industry and your worker count.
| Step | Authority (as listed) | What to ask your contractor |
| Building plan approval | GIDC for estate plots, or the urban development / local authority | Will your drawings meet its format? |
| Factory plan approval | Labour and Employment Dept. / DISH, with a stability certificate from a competent person (IndiaFilings) | Who issues the stability certificate? |
| Fire NOC | Fire department under the Gujarat Fire Act, 2013 | Is fire design in scope? |
| Consent to Establish | GPCB, where applicable | Does your industry need it? |
| Factory licence | DISH under the Factories Act | Who files, you or the contractor? |
The Gujarat Single Window Clearances Rules, 2017 list these approvals with prescribed timelines. Check current timelines on the official portals. A 2020 state notification said factories must submit a fire NOC with new licence applications and renewals. The Factories Act applies to premises with 10 or more workers using power, or 20 or more without.
Ask every contractor in writing: “Which of these approvals do you prepare drawings for, and which do you file?”
Is a PEB structure manufacturer the same as a turnkey contractor?
No. A PEB structure manufacturer fabricates the steel building system. A turnkey contractor is accountable for the whole project, including foundations, civil work, utilities and handover. Some companies do both, so ask who is responsible where the steel meets the concrete, because that interface is where site delays and disputes usually start.
If you buy steel from one party and civil work from another, you carry the coordination risk yourself. Anchor bolt positions, foundation tolerances and erection sequence must match exactly. A single contract moves that risk to the contractor.
How do you choose an industrial construction company in Ahmedabad?
Choose an industrial construction company by checking four things: completed projects similar to yours that you can visit, a written scope with exclusions, named responsibility for approvals and the steel–civil interface, and milestone-based payments. A price that is far below other quotes usually means something is missing from the scope.
Decision checklist: ask every contractor:
- Can I visit two completed projects of similar size and type?
- Can I speak to the owners of those projects?
- Who designs the structure, and who signs off the drawings?
- Is design and fabrication in-house or subcontracted?
- Who is accountable for the foundation?
- Which approvals do you prepare, and which do you file?
- How are payments tied to progress?
- What documents do I receive at handover?
Advice from PEB-vendor guides points the same way: look at the sectors a vendor has worked in, references and delivery record.
Common mistakes:
- Comparing ₹/sq ft rates without comparing scope
- Skipping the site visit to a finished project
- Leaving foundation and flooring “to be decided”
- Paying large advances before drawings are approved
- Assuming approvals are included without asking
What are the stages of an industrial turnkey project?
An industrial turnkey project moves through six stages: requirement consultation, planning and design approvals, construction, installation and setup, finishing and testing, and handover with support. Your approval should be required before site work begins, and handover should include documents, not just keys.
- Requirement consultation: your operations, site, budget and timeline.
- Planning and approvals: layouts, structural drawings and estimates for your sign-off.
- Construction: foundations, steel fabrication, erection, roofing and cladding.
- Installation and setup: flooring, electrical points, mezzanine and racking, if required.
- Finishing and testing: structure, electrical, drainage and fire safety checks.
- Handover: documents, walkthrough and post-handover support.

FAQ
Is a turnkey contract the same as an EPC contract?
Not exactly. EPC describes the contract structure (engineering, procurement, construction), while turnkey describes the obligation to deliver a facility ready to operate. Most fixed-price EPC contracts for factories are turnkey, but check how the contract defines “completion.”
How much does industrial shed construction cost per sq ft in India?
Published rates vary widely because they cover different scopes: one vendor guide cites roughly ₹300–600 per sq ft for frame, cladding and roofing, while another cites ₹1,200–2,600 per sq ft for complete PEB sheds in 2026. Always ask what the rate includes before comparing quotes.
Does a factory need approvals before construction starts in Gujarat?
Generally yes. Gujarat’s factory process requires approved building plans before registration, and a fire NOC is required with licence applications. Confirm the exact sequence for your plot with DISH, GIDC or your local authority.
Is a PEB structure manufacturer the same as a turnkey contractor?
No. A manufacturer fabricates the steel building system, while a turnkey contractor is responsible for the whole project, including foundations, civil work and utilities. Some companies do both, so ask who is accountable where steel meets concrete.
What should I ask for in a turnkey quotation?
Ask for a written scope with inclusions and exclusions, a bill of quantities, the design basis and drawings, payment milestones tied to progress, and a list of handover documents.
