Introduction

The defining advantage of prefab resort construction over conventional on-site building is factory manufacturing — the process of constructing resort buildings in a controlled factory environment, under consistent conditions, with trained specialist teams and comprehensive quality inspection, before delivering finished panels or modules to the project site. Understanding how this manufacturing process works helps resort developers make more confident decisions, set more accurate project expectations and engage more effectively with their prefab manufacturer throughout the construction journey.

This is Article 1 of Stage 6 — Manufacturing and Construction. It covers the complete factory manufacturing process for LGSF prefab resort cottages, from the receipt of design drawings in the factory to the completion of quality inspection and preparation for delivery to site.

Loom Crafts Expert Insight: The most important thing to understand about factory manufacturing for resort construction is that quality is built in, not inspected in. The controlled factory environment — consistent material storage, trained specialist teams, mechanised production processes, comprehensive incoming material inspection and systematic panel-level quality checks — produces structural frames and building panels that are inherently more consistent and more accurately built than equivalent structures assembled by casual labour on a remote resort construction site. Quality control in the factory is a production system. Quality control on a remote site is supervision — and supervision has limits.

1. The Manufacturing Process Overview

The manufacturing process for an LGSF prefab resort cottage follows a linear production sequence from raw material to finished panel. The sequence at Loom Crafts Prefab's Ghaziabad manufacturing facility is as follows:

  • Design drawings received and checked: Architectural and structural drawings for the specific cottage are reviewed by the production engineering team, translated into manufacturing drawings and released for production. Any design queries or dimensional discrepancies are resolved before production begins.

  • Material procurement and incoming inspection: Steel coils, Rockwool insulation, cement fibre board cladding, gypsum board lining, UPVC windows and door frames, and all hardware are procured from approved suppliers and inspected on arrival at the factory against material specifications.

  • Steel frame fabrication: Cold-formed steel sections are cut, punched and assembled into wall stud frames, floor joist panels and roof truss assemblies using precision roll-forming and assembly jigs.

  • Panel assembly: Wall panels, floor panels and roof panels are assembled on flat assembly tables — the stud frame is positioned in the assembly jig, Rockwool insulation batts are installed between studs, and internal lining boards are fixed to complete the panel assembly.

  • External cladding: Cement fibre board cladding is cut to size, finished as required and fixed to the external face of wall panels on a dedicated cladding line.

  • Window and door frame installation: UPVC window and door frames are positioned in pre-formed openings in wall panels and fixed and sealed in the factory — arriving on site as complete, weathertight panels.

  • Pre-wiring: First-fix electrical conduit and wiring is run within wall and floor panels in the factory, leaving service tails protruding from panel edges for connection on site.

  • Panel inspection and marking: Every panel is individually inspected against the manufacturing drawing, dimensionally checked and marked with the cottage number and panel reference for correct site installation sequence.

  • Protective packaging and loading: Completed panels are wrapped in protective film, stacked and secured on transport vehicles or flat-rack trailers for delivery to site.

2. Steel Frame Fabrication

Cold-Formed Steel Section Production

The structural steel sections used in LGSF construction are cold-formed — produced by passing galvanised steel strip through a series of precision roll-forming dies that bend the strip progressively into the required section profile (C-stud, U-track, Z-purlin) without heating the steel. Cold-forming preserves the full strength of the base metal while producing sections with precise dimensional consistency that hot-rolled sections cannot match.

Galvanising Specification

All structural steel sections used in Loom Crafts Prefab resort cottages are manufactured from pre-galvanised steel strip with a zinc coating of minimum 275 grams per square metre (equivalent to approximately 20 microns per face) applied in the steel mill before roll-forming. This mill-applied galvanising provides comprehensive corrosion protection to the entire section surface — including cut edges, which are protected by the zinc in adjacent uncut areas through galvanic action.

Assembly Jig Production

Steel sections are assembled into wall panels, floor panels and roof trusses in dedicated assembly jigs — precision-made steel frames that hold all components in their correct positions and angles while self-drilling screws are driven to complete the structural connections. Assembly jig production eliminates the dimensional variation that arises when panels are assembled by hand-measurement on a flat floor — every panel produced in a given jig is dimensionally identical, simplifying site installation and ensuring that panels from different production runs fit together correctly.

3. Panel Assembly

Wall Panel Assembly Sequence

  • Bottom track positioned in assembly jig on flat assembly table

  • Vertical steel studs positioned at specified centres (typically 400mm or 600mm) and fixed to top and bottom tracks with self-drilling screws

  • Structural headers installed above window and door openings

  • Rockwool insulation batts cut to size and fitted between studs — tight fit, no voids

  • Internal gypsum board or cement board lining fixed to stud faces using self-drilling screws at specified intervals

  • Panel removed from assembly jig, turned, and external cladding fixed to opposite face

  • Window or door frame installed in pre-formed opening

  • Panel marked with cottage number and panel reference

  • Panel inspected against manufacturing drawing

Floor Panel Assembly

Floor panels are assembled using cold-formed steel floor joists spanning between perimeter support beams — the same assembly jig process as wall panels. A structural floor deck (typically cement board or engineered timber sheet) is fixed to the top face of the floor panel to provide the structural floor diaphragm and the substrate for the finished floor covering. Floor panels are typically produced as complete room-sized units — one panel per bedroom, one for the living area, and so on — minimising the number of on-site joints and assembly operations.

Roof Panel and Truss Assembly

Roof structures are produced as either prefabricated roof trusses (for pitched roofs) or as flat roof panels (for low-slope applications). Pitched roof trusses are assembled in dedicated truss jigs — ensuring that every truss has the correct geometry and that truss-to-truss dimensional consistency allows uniform rafter spacing across the completed roof. Roof panel insulation (Rockwool between rafters or across flat roof joists) is typically installed on site rather than in the factory, as the open geometry of the roof structure makes factory insulation installation impractical.

4. Insulation, Lining and Cladding

Rockwool Insulation Installation

Rockwool mineral wool insulation batts are cut to the exact stud spacing of each panel and installed tightly between studs, with no gaps or voids that would create thermal bridges or reduce acoustic performance. The density and thickness of the Rockwool specified for each panel is determined by the thermal and acoustic performance requirements of that specific panel type — heavier-density Rockwool for higher acoustic performance in inter-cottage walls; standard density for external walls where thermal performance is the primary requirement.

Internal Lining

The internal lining board — gypsum board in standard dry applications, cement board in wet area wall panels (bathrooms) — is fixed to the internal face of the stud frame using self-drilling screws at the specified grid spacing. The screw spacing is critical to the structural performance of the wall panel as a shear diaphragm — undersized screw spacing reduces the racking resistance of the panel. In factory production, screw spacing is controlled by a template rather than by the judgement of individual operatives.

External Cladding Application

Cement fibre board cladding is cut on a panel saw to the exact dimensions of each wall panel, and fixed to the external face of the stud frame through the building wrap (breathable moisture barrier) using stainless steel screws into every stud. The building wrap is applied continuously across the full panel face before cladding is fixed — this is the critical waterproofing layer that prevents moisture from reaching the steel frame and insulation in the event of any penetration through the outer cladding surface. Factory application of the building wrap and cladding ensures continuous, uninterrupted coverage with no gaps at panel edges.

5. MEP Pre-Installation

First-Fix Electrical Pre-Wiring

First-fix electrical work — the conduit runs and wiring that must be installed within the wall and floor construction before surfaces are closed — is completed in the factory for all wall panels that will contain electrical services. Conduit runs are cut into the back of the internal lining board, wiring is pulled through and service tails are left protruding from the panel edge at specified positions for connection to adjacent panels on site. Factory pre-wiring eliminates the on-site cutting of channels in finished lining boards, reduces the risk of incorrect cable routing and significantly reduces the on-site second-fix electrical work required after installation.

First-Fix Plumbing

Where bathroom or kitchen wall panels contain supply pipes or drain pipes, first-fix plumbing work — cutting pipe runs into the panel, installing stub-out fittings at fixture positions — is completed in the factory. Plumbing pre-installation in the factory requires close coordination with the site plumbing contractor to ensure that stub-out positions and heights match the fixture specifications for the specific cottage design. Any dimensional discrepancy between factory plumbing stub-outs and site fixture positions creates costly remediation work.

6. Quality Control During Manufacturing

Incoming Material Inspection

Every material batch arriving at the factory is inspected against the material specification before it is accepted into production. Steel strip is checked for galvanising weight, section dimensions and yield strength against mill certificates. Rockwool is checked for density and dimensional consistency. Cement fibre board is checked for thickness, surface finish and moisture content. Materials that fail incoming inspection are quarantined and returned to the supplier.

In-Process Quality Checks

  • Frame assembly: Stud spacing checked against drawing; screw count and pattern verified; openings checked for squareness using diagonal measurement

  • Insulation installation: All stud bays checked for complete insulation fill; density verified by weight measurement of cut batts against specification

  • Lining board: Screw spacing verified against template; board joints checked for correct staggering; any damaged boards rejected before cladding is applied

  • Cladding: Panel dimensions checked against manufacturing drawing; screw spacing and penetration depth verified; cladding surface inspected for damage

Final Panel Inspection

Every completed panel is given a final inspection against the manufacturing drawing before it is marked, packaged and cleared for loading. The final inspection checks overall panel dimensions (length, width, squareness), opening positions and dimensions, window and door frame installation, building wrap continuity, cladding surface condition and correct panel marking. Panels that fail final inspection are rectified before they leave the factory.

7. Factory Capacity and Production Timelines

Production Timeline for a Resort Cottage

  • Design drawing to manufacturing drawings: 3 to 5 working days

  • Material procurement (where not in stock): 5 to 10 working days

  • Steel frame fabrication for one cottage: 3 to 5 working days

  • Panel assembly, insulation and lining: 5 to 8 working days

  • Cladding, windows and doors: 3 to 5 working days

  • MEP pre-installation: 2 to 3 working days

  • Inspection, packaging and loading preparation: 1 to 2 working days

  • Total factory production time for one cottage: 4 to 6 weeks from manufacturing drawing release

Concurrent Production

Loom Crafts Prefab's production facility manufactures multiple cottage units simultaneously on parallel production lines — typically 8 to 15 cottages in various stages of production at any given time. For a resort project of 10 to 15 cottages, a phased production schedule delivers the first 2 to 3 cottages for early installation while subsequent cottages continue through production — allowing the on-site installation team to commence work while the factory continues manufacturing.

8. From Factory Sign-Off to Site Delivery

Once a panel or module batch has passed final inspection and been cleared for delivery, the logistics process begins. Completed panels are wrapped in protective film to prevent transit damage, stacked on timber bearers on the transport vehicle in the planned installation sequence (panels to be installed first loaded last, on top), and secured with ratchet straps for road transport.

A detailed delivery manifest is prepared listing every panel, its cottage number, its panel reference and its installation position — allowing the site installation team to unload panels in sequence and confirm delivery completeness against the manifest. Any transit damage identified on delivery is documented on the delivery manifest and reported to the factory for immediate rectification or replacement.

Frequently Asked Questions

1. Can I visit the Loom Crafts Prefab factory to see manufacturing in progress?

Yes. Loom Crafts Prefab welcomes resort developer factory visits at the Ghaziabad manufacturing facility. Factory visits are typically arranged after the project design is confirmed and provide an opportunity to see the manufacturing process for your specific cottage design in progress. Contact Rahul Jindal at rahul@loomcrafts.com to arrange a factory visit.

2. How is quality controlled in factory manufacturing vs on-site RCC construction?

Factory manufacturing quality is controlled through production systems — incoming material inspection, assembly jigs, in-process quality checks and final panel inspection — applied consistently to every panel by trained specialist teams working under supervision. On-site RCC construction quality is controlled through site supervision — and in remote resort locations, the quality of supervision is highly variable. Factory manufacturing produces significantly more consistent quality than on-site construction in remote locations.

3. What happens if a panel is damaged during transit?

Transit damage is documented on the delivery manifest at the time of delivery and immediately reported to the Loom Crafts Prefab production team. For minor damage — surface scratches, cladding dents — rectification is carried out on site by the installation team. For major structural damage, a replacement panel is manufactured and delivered. Panels are packed with protective wrapping and loaded in a sequence that minimises the risk of transit damage.

4. How early in the project do I need to confirm the cottage design for factory manufacturing to begin?

Factory manufacturing can begin as soon as architectural and structural drawings are finalised and the manufacturing drawing set has been produced — typically 3 to 4 weeks after design finalisation. For a resort project targeting a specific opening date, design must be finalised sufficiently in advance to allow the full factory production and site installation timeline to be completed before the opening date.

Conclusion

Factory manufacturing is the foundation of prefab quality — and understanding the manufacturing process helps resort developers engage more effectively with their prefab manufacturer, set more accurate project expectations and make more confident investment decisions. Every panel that arrives on your resort site has been manufactured by trained specialist teams under controlled conditions, inspected against manufacturing drawings and cleared for delivery — representing a level of quality assurance that on-site construction in remote resort locations cannot replicate.
