Building a home or investing in property is one of the biggest financial decisions many Kenyans make. It is a dream that often takes years of planning, saving, and sacrifice. However, when mistakes happen during construction, that dream can quickly turn into a costly burden. In a recent discussion on Mwelekeo TV, structural engineer Eng. Paul Kodo shared important insights on how property owners can avoid common construction mistakes and protect their investments.
Through such conversations, Mwelekeo TV continues to be a go-to platform for practical knowledge, bringing together experts who help viewers make informed decisions about issues that affect their daily lives.
According to Eng. Kodo, many construction problems begin long before a building is completed.
Cracks on walls, uneven floors, sinking foundations, and even building failures are often signs of mistakes that occurred during planning, design, or construction.
While some people may think a building collapses suddenly, structural issues usually develop over time before becoming visible.
One of the most common mistakes is failing to involve a structural engineer from the beginning of a project.
Many homeowners focus on architectural drawings because they show the appearance and layout of the building.
While this is important, structural engineering is what ensures the building is strong enough to support its weight, withstand environmental conditions, and remain safe for many years. Without proper structural calculations, important elements such as beams, columns, and slabs may not be designed correctly.
Eng. Kodo explained that supervision during construction is just as important as the design itself.
Even when a building has a good design, problems can arise if the work on site does not follow the approved plans.
Sometimes contractors may use different materials or alter specifications in an effort to reduce costs.
Regular site inspections by a qualified engineer help identify such issues early and ensure that construction standards are maintained throughout the project.
Another important factor is understanding the type of soil on which a building will stand.
Different parts of Kenya have different soil conditions. Black cotton soil, for example, expands when it absorbs water and shrinks when it dries.
If this characteristic is not considered during foundation design, serious cracks and movement can develop in the structure.
Soil testing allows engineers to determine the most suitable foundation for a specific location, helping to prevent future problems.
The quality of construction materials also plays a major role in the strength of a building.
Steel, concrete, and other materials are manufactured to meet certain standards.
Choosing cheaper materials without proper professional advice may reduce costs in the short term, but it can compromise the safety and durability of the entire structure.
Since much of the structural work is hidden after construction is completed, weaknesses may remain unnoticed until significant damage appears.
Many people hesitate to hire structural engineers because they view the service as an additional expense.
However, Eng. Kodo noted that the cost of professional engineering services is usually a small fraction of the overall construction budget.
In return, it helps safeguard a much larger investment.
A properly designed and constructed house can serve several generations, while poorly executed work may require expensive repairs within a few years.
He also pointed out that even seemingly simple structures such as perimeter walls require proper engineering.
Heavy rains, unstable soil, and weak foundations can cause walls to fail if they are not designed correctly. Modern building methods such as pre-cast construction can improve efficiency, but they still require proper engineering guidance to ensure safety and stability.
Eng. Kodo encouraged Kenyans to view structural engineering as an investment rather than a cost.
Proper planning, professional design, quality materials, soil testing, and regular site inspections all contribute to a safer and more durable building.
By following expert advice and avoiding shortcuts, property owners can reduce risks and protect their investments for many years.
Mwelekeo TV continues to play an important role by connecting viewers with industry experts and practical knowledge.
Through informative discussions such as this one, the platform remains a trusted destination for Kenyans looking to make smarter decisions, avoid costly mistakes, and build structures that can stand the test of time.
