Stacked for Success - The Rise of Modular Building

Across Africa, developers are under growing pressure to deliver infrastructure faster, more efficiently, and at lower cost. As urban populations expand and governments push to close housing and healthcare gaps, modular construction is rapidly emerging as a practical solution.

From residential developments to hospitals, mining accommodation, and remote infrastructure projects, modular building techniques are increasingly being integrated into mainstream construction delivery. Modular construction involves manufacturing building components — such as walls, floors, bathrooms, or entire volumetric units — in a controlled factory environment before transporting them to the site for final assembly. This approach can significantly reduce construction timelines, improve quality control, and minimise on-site disruption.

While the advantages are clear, modular construction introduces a different risk profile from traditional building methods. Contractors, developers, and project stakeholders must therefore understand how these risks arise and how they should be managed.

One of the most significant challenges across many African markets is the limited availability of local modular manufacturing facilities. As a result, modules are often fabricated overseas, commonly in Europe, Asia, or the Middle East. Projects can therefore be vulnerable to shipping delays, port congestion, customs clearance risks, foreign exchange volatility, handling and assembly risks, and insurance complexities.

Installation also presents technical challenges. While modular construction reduces on-site labour requirements, it requires contractors to have skilled installation teams and precise coordination. Incorrect installation or poor integration of mechanical, electrical and plumbing systems can compromise structural integrity and overall building performance.

Given these complexities, contractual risk allocation becomes particularly important. Unfortunately, many standard form construction contracts do not adequately address the specific risks associated with modular construction and therefore often require amendment.

Modular construction projects require careful contractual structuring. Depending on the procurement route — such as design-build or EPC (Engineering, Procurement and Construction) — risk allocation should address issues including on-site inspections, title transfer of off-site materials, storage and insurance obligations, force majeure during shipping, testing and commissioning responsibilities, and latent defect liability.

From an insurance perspective, both contractors and developers need to consider several types of cover. These may include marine cargo insurance, storage insurance for off-site components, Erection All Risks (EAR) policies, and Delay in Start-Up (DSU) coverage. Failure to align contractual provisions and insurance arrangements with the realities of modular construction can leave significant gaps in protection.

As urbanisation accelerates and governments push for expanded affordable housing and healthcare infrastructure, modular construction is likely to play an increasingly important role across Africa.

For developers, contractors, lenders, and governments, the key to success lies not simply in adopting modular construction — but in ensuring that the risks it introduces are properly identified, allocated, and managed from the outset.
