Expert, Babatunji Adegoke highlights the role of AI and Sustainability in Construction

Unlike other industries such as manufacturing and media, the construction industry is evolving slowly and steadily with emerging digital technologies that are transforming the industry and artificial intelligence (AI) is at the forefront of these technologies. AI’s potential applications are vast, ranging from generating designs traditionally done by professionals such as Engineers and Architects to predicting potential safety hazards on construction sites. While AI offers increased speed and efficiency, its ethical implications and possible impact on the employment of Professionals are subjects of debate, Babatunji Adegoke explains.

It’s pertinent to note Adegoke is a seasoned project manager with over 15 years of experience in various sectors. He holds degrees in Civil Engineering and Construction Management from the University of Lagos and is a member of several professional institutions. And he has executed multi-million dollar projects in banking, residential, offices, mixed-use developments, and infrastructures.

Concerns about job displacement are understandable as Adegoke believes that AI will ultimately augment, not replace, human professionals. He points out that, “The construction industry, in particular, relies heavily on human judgment and experience, aspects that are difficult to replicate in digital machines like AI. The benefits of AI can not be over-emphasised as it has made the work of professionals in the construction industry easier and faster by analysing data for instance to predict project outcomes in terms of cost, time and budget adherence, empowering project teams to make informed decisions. 3D printing on the other hand has gained traction in the manufacturing industry unlike in construction where its use is still quite minimal, especially in Africa. In the manufacturing industry, for instance, it is easier to print a replacement component of a machine in any part of the world without the need to import the material physically. This saves time and other resources while also promoting sustainability because of the reduction in carbon emissions associated with importing the component. 3D adoption in Nigeria’s construction industry lags behind more developed countries.”

Sustainability has become a buzzword in construction, but its true meaning is often misunderstood Adegoke states. He further explains that, “Many equate it solely with planting trees and creating green spaces. While these are important aspects, sustainability encompasses far more than environmental concerns. It is a holistic concept built on three pillars: social, economic, and environmental. When considering sustainability in road infrastructure construction, for example, the impact on surrounding communities, the natural habitat, and employment opportunities must all be taken into account. If demolitions are necessary, the effects on property owners’ lives, health, and livelihoods must be considered. Sustainability is finding the right balance between these three pillars to achieve the best overall outcome. It’s not just about planting trees; it’s about making responsible decisions that benefit society, the economy, and the environment. It has always been a concern to me when I see many of our historic buildings demolished for newer structures, as a professional in the construction industry, I strongly believe that demolition should always be a last resort.”

Adegoke also believes that Construction companies can successfully integrate eco-friendly practices without sacrificing cost-effectiveness and profitability. A key strategy is prioritizing locally sourced materials and labour over imported ones. Every community possesses unique resources that can be incorporated into construction he points out. Traditional architectural designs, like those from the 70s and 80s, often utilized local materials like gravel for decorative wall finishes, examples of which can still be seen today. Other materials like raffia and bamboo can also be used raffia for decoration and bamboo as a sustainable alternative to steel in lightweight structures. Engineering designs can also minimize energy consumption by incorporating natural lighting and ventilation, rather than completely sealing off spaces designed for this purpose.

He adds that, “Older buildings often prioritized these features, unlike many modern structures that rely heavily on artificial lighting and mechanical ventilation. Harmonizing structures with the natural environment further enhances eco-friendly practices. In road construction, for example, minimising disruption to mountains and natural vegetation preserves the environment and adds aesthetic value for road users. By strategically incorporating these eco-friendly practices, construction companies can achieve cost savings on projects while simultaneously improving profitability.”

One practical approach to sustainable construction is to draw inspiration from traditional building practices, such as the construction of old mud houses. These structures were built using locally sourced materials like mud, raffia, and rafters, and were often constructed by community members working together. The homes were also designed to provide natural ventilation and warmth, eliminating the need for energy-intensive mechanical systems. And they also fostered a sense of community and were conveniently located near farms, promoting self-sufficiency. By incorporating these time-tested principles into modern construction, Adegoke believes that companies can adopt eco-friendly practices without sacrificing profitability. This approach emphasizes the use of local materials, community involvement, energy efficiency, and a harmonious relationship with the surrounding environment.
