What once took three to five years can now be delivered in months. Modular construction is a fundamental rethink of how hospitals get built.

In a country like India, where around 1.4 billion people demand access to quality healthcare, every minute counts. Considering the ratio of hospital availability to the total number of sick patients, the time frame to build hospitals is critical to maintaining the balance of medical delivery.

How modular construction compresses the construction timeline

Traditional construction processes are known to be not only slow but also costly. Modular construction is an innovative way to address this challenge by constructing 90% of buildings in pieces in a factory-controlled environment and assembling the remaining 10% on-site. Think of it like Lego blocks put together.

These ‘Lego blocks’ are built in an off-site manufacturing facility, using precision engineering and autonomous unit modules, including interiors, structural components, plumbing, electrical, and medical gas service. These are then transported to actual construction sites and integrated into core infrastructure. In many ways, it’s a plug-and-play system for construction.

While the base and critical facilities are built on-site, the manufacturing facility builds other parts simultaneously. Such a parallel workflow approach ensures faster construction, less site disruption, and greater cost savings.

The disturbing Covid-19 pandemic was a stark reminder of the medical infrastructure gaps. It highlighted the need to accelerate the construction of new hospitals to accommodate high occupancy rates. Intelligent and prefabricated medical buildings are a solution that can deliver this without compromising on the quality.

Modular construction reduces material waste by 80%, accelerates project durations by 50%, and offers around 20% in cost savings.

In a better-controlled environment, one can gain better Quality Assurance (QA) and Quality Control (QC), with no lost days due to rain or snow. Combining off-site fabrication and robust digital tools mitigates manual errors, enhances productivity and fosters environmental sustainability.

The controlled off-site environment acts as a strict quality filter, eliminating the defects common to manual on-site labor. 'Visualised using AI'

Tata Steel Main Hospital is an extraordinary marvel of modular construction in India. The hospital stands on 90,000 square feet with a G+2 structure (ground floor plus two additional upper floors) serving 133 beds. Built by Nest-In, Tata Steel Main Hospital is located near Noamundi, Jharkhand. Using advanced modular and prefabricated technologies, Nest-In delivered the entire hospital within 18 months, twice as fast compared to conventional methods.

The prefabricated hospital offers expansive facilities, from 12 fully-equipped OPDs, rooms, and wards to radiology and general pharmacy. The hospital was designed with noise and thermal insulation to align with medical environment requirements. Although prefabricated, it encapsulates seismic resistance for Zone 2, fire resistance for up to 2 hours, and meets all required safety standards.

Nest-in claims that its solutions use around 60% less materials, 50% less freshwater, and 50% less environmental impact than traditional methods.

Cost benefit analysis

A Construction Industry Institute (CII) study highlights that a modular approach to construction reduces cost by 10%-25%. The standardised design procedure involves less engineering and time when compared to conventional construction. However, the initial cost of setting up a manufacturing facility is often a factor that is ignored.

In reality, modern prefab/modular construction has moved far beyond “experimental” and is being successfully implemented across hospitality, housing, healthcare, and commercial infrastructure globally and in India. Yet, it faces skepticism, primarily around transportation and logistics of modular components. Prefabricated modules aren't standard freight. Specialist transport requirements can add cost and delay, directly undermining the efficiency case for modular builds.

Overcoming logistics of modular components

Discussing these challenges, Rahul Jindal, MD of Loom Crafts Furniture India Pvt Ltd says, “The skepticism around modular construction usually comes from a lack of on-ground exposure and outdated perceptions.”

Creating modular and prefab units for a decade, he shares that units are engineered for safe road transport with structural reinforcements, and large projects are broken into optimised sub-modules to suit Indian road conditions. Route planning, escort vehicles (if required), and night movement reduce risk and delays. These practices are already standard in infrastructure and heavy equipment industries.

Also, crane dependency is a one-time installation activity, not a continuous requirement in modular construction. In remote areas, lighter modular systems or segmented assembly methods are used. Overall, crane logistics replace months of manual labor and formwork on-site.

In order to overcome skepticism around prefabricated modules, Rahul opines, “Companies should build pilot projects and show real, operational case studies. Encourage site visits to live modular projects and share lifecycle cost comparisons (time saved = money saved).”

He emphasises that we need to position prefab not as “temporary structures” but as engineered permanent buildings with predictable performance, durability, and ROI.

Scaling modular for affordable housing

The ultimate advantage of modular design is scalability: turning one perfected structural blueprint into a massive, rapidly deployable housing program. 'Visualised using AI'

Modular construction is a method of building, not a different category of building. This method of construction can, therefore, be leveraged to scale affordable housing. Rahul strongly believes that modular construction is one of the most powerful tools to scale affordable housing because it directly attacks the biggest bottlenecks: time, cost, skill shortage, and quality inconsistency.

As speed is critical in affordable housing where margins are tight, 40–60% faster project completion means lower financing costs, faster occupancy, and quicker revenue realisation. Modular-focused architecture enables the construction of hundreds of units per month with standard unit types (1BHK, 2BHK) that can be replicated across multiple cities.

Rahul adds that governments, developers, and NGOs can plan housing in phases without quality dilution. This makes it possible to move from ‘projects’ to programmes of housing development.

And one significant advantage of these overall benefits is sustainability. Lower construction waste contributes to reduced on-site pollution and noise, and results in better energy performance, aligning with ESG goals and government sustainability mandates.

“Modular construction is not an alternative to traditional construction, it’s an industrialised evolution of construction that brings predictability, speed, and scalability to housing and hospitality projects”, concludes Rahul.

Modular construction offers immense benefits, but only when done right. While it might take time for the modular approach to become mainstream, it certainly presents appealing opportunities for contractors to expand their business in a scalable manner.
