Prefab Modular Construction

Prefab modular construction is how SAMAN builds a commercial or industrial building as a set of complete, factory-built sections that are bolted together on your site — and engineered from day one to take more sections later. We design, fabricate, and erect the building from our facilities in Bangalore and Greater Noida; you receive a finished structure, not a kit to assemble. The build shown on this page is a 120 × 30 × 20 ft modular structure — 3,600 sq ft of floor area on a steel frame with PUF sandwich panels — constructed and handed over for ₹31,85,000 to ₹31,95,000, inclusive of all taxes.

What Is Prefab Modular Construction?

Prefab modular construction is a building method in which the structure is fabricated off-site as complete volumetric modules, transported to site, and bolted together on a prepared foundation. Unlike a single fixed pour, the building is engineered in sections — so bays can be added, floors stacked, or whole modules removed and re-erected elsewhere without rebuilding what already stands.

Because each module leaves the factory largely complete, the on-site phase is assembly rather than wet construction. If you want the wider picture of factory-built methods across every building type, that is covered by the broader prefabricated construction method; this page is specifically the modular, sectional route.

Building in Sections — and Engineering for Bays You Add Later

A new modular section craned onto the existing frame — adding a bay without disturbing what already stands.

What lets a modular building grow without structural rework is a decision taken at design stage, not after. When we engineer your modular building construction, the primary frame and the foundation are sized for the building you may have in two years, not only the one you order today — the end portal frame is left ready to receive the next bay, and the plinth is cast to the full future footprint where you expect to expand. Adding an expansion bay later is then an assembly job: a new factory-built section arrives, its frame bolts to the existing end frame, and the roof and wall panels close the join. Because the structural steel frame we build on carries the load through bolted module connections rather than cast joints, nothing already standing has to be demolished or re-poured. Where you need height rather than width, a building set up for G+1 or G+2 at design stage lets you stack a floor on the same column line later.

Relocating a Modular Building to a New Site

A modular section unbolted and loaded for relocation — the building moves with the business, not written off.

A modular building is also one you can take with you. Because the structure is held together by bolted connections, the same sections assembled on site can be unbolted, loaded, and re-erected at a new location — the steel and panels become relocatable steel modules rather than a sunk cost in concrete. For a business on leased land, a project site with a fixed life, or an operation that may consolidate later, this turns the building into a movable asset rather than a write-off. Relocation is planned at order stage, so lifting points, panel fixings, and service routing are built to be opened and closed again.

What the 3,600 sq ft Modular Build Costs — and How It Sections

The 3,600 sq ft modular build — a 120×30×20 ft steel-and-PUF structure shown as evenly spaced sections.

The configuration on this page is a 120 × 30 × 20 ft building — 3,600 sq ft at a 20 ft eave height — built as bolted sections on a steel frame clad in PUF sandwich panels, constructed and handed over for ₹31,85,000 to ₹31,95,000 inclusive of taxes. That works out to roughly ₹885 per sq ft for the constructed structure, which sits below a monolithic single-pour build of the same area precisely because sectional, off-site fabrication is faster and repeatable. Our scope covers the steel frame, wall and roof panels, doors and windows as configured, transport, and erection by our own crew. You arrange two things: a level plinth poured to the layout drawing we issue, and utility connections after structural handover. Other sizes — and custom modular construction laid out around your process flow or a planned future expansion — follow the same method and are quoted per square foot.

When a Modular Build Beats a Fixed-Specification Building

A royal-blue modular building grown bay by bay — what choosing modular over a fixed build makes possible.

Modular is the right call when the building’s future is open: when you expect to add bays as the operation grows, may relocate, or want to phase the spend. If instead the building is permanent, fixed in size, and will not change, a building set to one fixed specification is simpler and usually costs less to detail, because nothing has to be left ready for a future join. And when your project is a large multi-bay factory or warehouse needing full design, IS-code documentation, and site coordination under one contract, that is our turnkey PEB construction service rather than a single modular configuration. Tell us the use and the likely five-year picture, and we will point you to the right one.

Frequently Asked Questions

How do I add a bay or a floor to a modular building later?

The work is planned before the first section is built. We provision the foundation and the end of the steel frame for the bay you may add, so when the time comes a new factory-built section is delivered, bolted to the existing frame, and closed with matching panels — no demolition. For added height, a frame designed for G+1 or G+2 lets a floor be stacked on the same columns.

How much does prefab modular construction cost?

The 120 × 30 × 20 ft (3,600 sq ft) modular build on this page is ₹31,85,000 to ₹31,95,000 inclusive of taxes — about ₹885 per sq ft for the constructed structure. Larger, smaller, or differently sectioned buildings follow the same method and are quoted per square foot.

Modular construction or a fixed-specification build — which should I choose?

Choose modular when you expect the building to grow, move, or be reconfigured; the sections are engineered to come apart and add on. Choose a building set to one fixed specification when it is permanent and will not change — it is simpler to detail and typically cheaper at the same size.

Is modular construction suitable for permanent commercial and industrial buildings?

Yes. The sections are built on a PEB-grade steel frame with PUF panels, not temporary materials, so a modular building serves as a permanent factory, warehouse, or commercial block — while keeping the expand-or-relocate option a poured structure cannot offer.
