Cost per bed = total accommodation project cost ÷ number of beds. A ₹20 lakh project with 100 beds works out to ₹20,000 per bed. Compare prefab and brick on the same scope, same number of beds and same facilities — and include timeline, relocation and reuse, not just construction cost.
Setting up accommodation for workers is an important part of any large construction, infrastructure, manufacturing, EPC or industrial project. But when the requirement is for 50, 100, 200 or more workers, the question is not simply where they will stay.
The bigger questions are: How much will the labour colony cost per bed? How quickly can it be built? How much land is required? Can the structure be reused? What happens when the project moves?
Traditionally, worker accommodation has been constructed using brick walls, RCC, plaster, masonry and conventional civil work. Today, prefabricated labour colonies and modular accommodation provide an alternative that can be faster to install and more flexible for temporary or semi-permanent projects.
What does "cost per bed" mean in a labour colony?
Labour colony cost per bed is a practical way of comparing the total accommodation cost against the number of workers the facility is designed to house.
Cost per bed = Total accommodation project cost ÷ Number of beds
For example, if a labour accommodation project costs ₹20 lakh and provides 100 beds, the cost is ₹20,000 per bed.
A proper comparison should also consider worker rooms, toilets, kitchen, mess, electrical installation, lighting, ventilation, flooring, doors/windows, water supply, drainage, insulation, fire and safety provisions, site preparation, transportation and installation.
Prefab labour colony vs traditional brick: cost comparison
Traditional brick construction typically involves foundation, brick/block masonry, RCC or structural work, plaster, flooring, electrical/plumbing work, doors/windows, painting and finishing.
A prefabricated labour colony can use a steel/MS structural framework, PUF/EPS or other insulated panels, roofing systems, prefabricated wall panels, doors and windows, flooring systems and modular utility components.
There is no single fixed cost per bed because accommodation standards vary. A basic worker dormitory with bunk beds and shared toilets will have a very different cost structure from a fully equipped labour township with attached bathrooms, kitchen, dining space, air conditioning and premium insulation.
Why prefab can be cost-effective for labour colonies
The biggest advantage of prefab is not necessarily that every component is cheaper than brick construction. The advantage comes from overall project economics.
Prefab can reduce costs associated with construction duration, on-site labour, material wastage, site supervision, project delays, wet construction, rework, future relocation and repeated construction for multiple projects. For a contractor managing several projects, these savings can become more important than the initial material price difference.
1. Construction time: prefab vs brick
Traditional brick construction involves several sequential activities such as masonry, plastering, curing, flooring, electrical and plumbing work, painting and finishing.
Prefab shifts a substantial amount of work away from the project site. Components can be designed, engineered, manufactured or prepared, transported, assembled and connected at the site. For projects where workers need accommodation quickly, reducing construction time can reduce temporary accommodation, transportation, idle labour, extended mobilisation and site management costs.
2. Prefab labour colonies reduce wet construction
Traditional construction usually involves cement, sand, bricks/blocks, water, plaster, mortar, concrete and paint. Prefab systems can reduce dependence on several wet construction activities.
This can be useful at remote project sites where water availability is limited, skilled masonry labour is difficult to arrange, material transportation is expensive, construction time is restricted or weather affects construction activities.
3. Labour requirement and installation
Traditional construction requires different trades throughout the project, including masons, helpers, plaster workers, electricians, plumbers, painters, flooring workers and fabricators.
Prefab still requires skilled installation teams, but the workflow can be more controlled because many components are manufactured or prepared in advance. This can reduce dependence on prolonged on-site construction labour.
4. Less material wastage
Traditional construction can generate waste from broken bricks, mortar, cement, sand, cutting, plaster, packaging and rework.
Prefab components are manufactured according to predetermined dimensions and specifications, allowing more controlled material usage. For a large labour colony with hundreds of rooms, even small reductions in material wastage can become meaningful.
5. Reusability: the major advantage of prefab
For EPC contractors, infrastructure companies and project-based organisations, reusability can be a major advantage. A traditional brick labour colony is generally constructed for one location and is difficult and expensive to dismantle and relocate.
A properly designed prefab structure can potentially be dismantled, transported and reassembled at another project, subject to structural condition, logistics and site requirements. The financial question becomes: what is the cost of the accommodation asset over its entire usable life rather than only its first project? (See how reusable prefab cabins cut cost across 3 project cycles.)
6. Traditional brick construction may still make sense
Traditional construction can make sense when the building is intended to be permanent, the site is not expected to change, local construction labour is readily available, conventional construction is preferred by the client, the project has a long operational life, or a permanent civil structure is required.
If a company is constructing a permanent residential township that will remain in one location for decades, traditional construction may be worth considering.
7. When prefab is usually more attractive
Prefab labour accommodation becomes especially useful when the project is temporary or semi-permanent, remote, large-scale, under a tight mobilisation schedule, or when a company has multiple projects and may want modular expansion or relocation.
8. PUF insulation can improve worker comfort
Worker accommodation should not be evaluated only on construction cost. Thermal comfort is also important, especially in Indian climates.
Prefab buildings can be designed using insulated panels such as PUF panels, depending on thermal requirements. Proper insulation can help reduce heat transfer through the building envelope. The appropriate panel thickness and insulation specification should be selected according to project location, room usage and HVAC requirements.
9. Maintenance: what should contractors consider?
Maintenance cost depends on the quality of materials and installation — not simply whether a building is prefab or brick.
Key areas include roof condition, wall panels, steel structure, waterproofing, plumbing, electrical systems, flooring, doors and windows, drainage, sanitary fixtures and corrosion protection. A well-engineered prefab building with proper maintenance can remain functional for a long period. Likewise, poor-quality prefab construction can create problems. The contractor, material specification and installation quality matter.
10. The real comparison: cost per bed vs total cost of ownership
Instead of asking only which method has the lower construction cost, ask which solution gives the lowest total cost for the required number of workers over the complete project lifecycle.
Consider initial construction cost + site preparation + transportation + installation + maintenance + project delay cost + worker accommodation during construction + dismantling cost + relocation cost + residual/reuse value.
Example: 200-worker labour camp
Suppose an EPC contractor needs accommodation for 200 workers. The project team should establish the number of rooms, beds per room, total built-up area, toilet/bathroom ratio, kitchen/mess, drinking water, electrical load, ventilation, insulation, storage, common areas and other requirements.
For example, if 8 workers are accommodated per dormitory room: 200 ÷ 8 = 25 dormitory rooms.
The final project comparison should include structure, panels, roofing, flooring, electrical, plumbing, sanitary, doors/windows, transportation, installation, foundation/site work and finishing. For the execution side, read how to set up a 200-worker labour camp in 30 days.
How to calculate your labour colony cost per bed
- Define worker capacity.
- Decide room occupancy.
- Define facilities such as toilets, kitchen, dining hall, laundry, store room and common areas.
- Calculate total built-up area.
- Obtain the complete project cost including structure, panels, roofing, flooring, electrical, plumbing, sanitary, doors/windows, transportation, installation, foundation/site work and finishing.
- Calculate: Total Project Cost ÷ Total Number of Beds = Labour Colony Cost Per Bed.
What should you ask the contractor?
Before placing an order, ask for a detailed quotation covering structural specifications, panel type and thickness, insulation, roofing, flooring, doors/windows, electrical work, plumbing and sanitary work, foundation requirements, transportation, installation, finishing, fire and safety requirements, warranty, maintenance, dismantling and relocation options, and estimated completion timeline.
Prefab vs brick: which is better for your labour colony?
There is no universal answer.
Prefab is generally worth evaluating when: accommodation is needed quickly; the project is temporary or semi-permanent; the site is remote; worker capacity is large; modular expansion is needed; relocation may be required; the company has multiple projects; or speed and lifecycle cost are important.
Traditional construction can be worth considering when: the building is permanent, the structure will remain at the same location for a long period, conventional civil construction is established at the site, project specifications require it, or the economics favour a permanent masonry structure.
Final verdict: focus on cost per bed, not just cost per sq ft
Cost per square foot alone does not tell the complete story. A better calculation is: cost per bed + construction timeline + maintenance + relocation + reusability + project delay costs.
For a temporary labour colony, a prefab solution can become particularly valuable because the structure may be designed around actual accommodation requirements and potentially reused at another site. For permanent accommodation, traditional construction can still be a strong option.
The best approach is to compare both systems using the same scope, same number of beds, same facilities and the same quality standards.
