Modular Construction Doesn’t Eliminate Site Labour: It Changes Where Skills Are Needed

Modular construction is often discussed as a solution to some of the biggest challenges facing UK construction: skills shortages, tight project programmes, rising costs and the need to build more efficiently.

With significant parts of a building manufactured off-site in controlled factory environments, it can be easy to assume that modular construction means fewer people are required on construction sites.

The reality is more nuanced.

Modular construction doesn’t remove the need for skilled site teams. Instead, it changes when, where and how those skills are required.

What Is Modular Construction?

Modular construction involves manufacturing sections or components of a building away from the final construction site before transporting them to site for installation.

Depending on the system being used, modules can arrive with substantial elements of the internal fit-out already completed.

This allows off-site manufacturing and on-site preparation to take place simultaneously, potentially creating a much more streamlined construction programme.

However, the arrival of the modules is only one stage of the project.

The Site Still Needs to Be Built

Before a modular unit can be installed, the site needs to be ready for it.

That can involve:

• Site preparation and enabling works
• Groundworks and drainage
• Foundations and concrete works
• Utilities and infrastructure
• Access roads and external works
• Crane preparation and lifting operations

These activities continue to require experienced construction professionals and skilled trades.

A modular building may arrive substantially complete, but it still needs somewhere properly prepared to go.

Installation Creates Different Labour Requirements

Once modules begin arriving, the nature of the site programme changes again.

Transport, lifting and installation need to be carefully coordinated. Depending on the project, contractors can require Site Managers, Supervisors, Crane Operators, Slinger/Signallers, Logistics Managers and specialist installation teams to ensure modules are installed safely and efficiently.

With components manufactured to specific tolerances and installation sequences, coordination becomes particularly important.

Rather than removing site labour, modular construction can create periods where specific skills need to be available at exactly the right point in the programme.

What Happens After the Modules Are Installed?

Installation isn't necessarily the end of the construction process either.

Modules may still require connections, commissioning, finishing and integration with the wider building and infrastructure.

That can create requirements across areas including mechanical and electrical works, carpentry and joinery, drylining, decorating, flooring, external works and final finishing.

Quality control and snagging also remain essential before a project can be handed over.

The balance of trades may be different from a traditionally constructed building, but people remain a critical part of delivering the finished project.

Some Jobs Move Off-Site

One of the biggest differences with modular construction is that some construction activity moves from the building site into a manufacturing environment.

Factories producing modular buildings can require production operatives, fabricators, electricians, plumbers, joiners, quality professionals, supervisors and managers.

This creates an interesting crossover between construction and manufacturing.

Workers who previously spent most of their careers moving between construction sites could increasingly find opportunities in permanent or semi-permanent manufacturing facilities, while contractors still require skilled teams to prepare sites and complete installation.

A Different Type of Construction Workforce

As modular construction develops, workforce planning may therefore become less about simply reducing headcount and more about having the right combination of people across factory, logistics and site operations.

A modular project can involve several interconnected workforces:

Manufacturing → Transport → Groundworks → Logistics → Installation → Fit-Out → Commissioning → Handover

If one part of that chain isn't properly resourced, the efficiencies offered by off-site manufacturing can quickly be undermined.

Recruitment Needs to Adapt Too

For recruiters working within construction, modular building presents an interesting challenge.

Traditional construction knowledge remains extremely valuable, but employers may increasingly look for candidates who can work across disciplines or understand manufacturing-led construction processes.

Experience of logistics, sequencing, quality control, installation and off-site manufacturing could become increasingly relevant alongside traditional trade and site-management experience.

It also means recruitment businesses need to understand that modular construction doesn't sit neatly within one recruitment sector.

It brings together construction, trades and labour, manufacturing, engineering and supply chain.

Building Differently Still Requires Good People

Technology and modern methods of construction will continue to change how buildings are delivered.

But construction becoming more efficient doesn't mean people disappear from the process.

Groundworks still need completing. Modules still need transporting. Cranes still need operating. Installations still need managing. Services still need connecting. Buildings still need finishing.

Modular construction doesn't eliminate site labour. It changes where skills are needed and makes having the right people available at the right stage of a project even more important.
