In 2010, a young Nigerian graduate named Oluwasola Adeolu walked into the offices of RATCON Nigeria Limited as a junior procurement officer. The job was hardly glamorous. His desk was stacked with invoices and tender documents. His phone calls revolved around negotiating with suppliers for cement, pipes, and steel reinforcement. Most of his colleagues were older and more experienced. Few could have predicted that within less than a decade, Adeolu would find himself in Qatar, working as a Quantity Surveyor and Cost Control specialist on some of the world’s most complex multi-billion-dollar oil and gas projects.
Today, as the Gulf state positions itself as the global leader in liquefied natural gas production, Adeolu has carved out a place among the professionals ensuring that these mega projects are not only built to world-class standards but delivered with financial discipline. His rise is as much a personal journey as it is a case study of how African engineering talent is finding its way into global projects.
Roots in Procurement
Adeolu’s story begins in Port Harcourt, Nigeria’s oil hub. At RATCON, he was assigned to projects linked to the Nigerian National Petroleum Corporation. Among them was the Flow Assurance Expansion Project at Port Harcourt Refinery, a job that exposed him to the unforgiving reality of cost overruns in the oil sector. He also supported the construction of internal roads within the refinery, work that demanded constant negotiation with suppliers and contractors.
“Procurement was my first classroom,” Adeolu recalls with a smile. “You learn very quickly that a project can only succeed if the numbers add up. It taught me to respect contracts, to think ahead, and to always protect both the company’s interest and the client’s.”
The skills he picked up, such as negotiating, cost benchmarking, and documentation, would become critical later in his career. But at the time, he was restless. Nigeria’s construction sector was slowing, while opportunities abroad beckoned. In 2012, he made the leap to Qatar, a country preparing to invest heavily in infrastructure and energy projects as it looked toward the 2022 FIFA World Cup and a new phase of LNG expansion.
Qatar: A Broader Canvas
Adeolu joined Horizon Progressive Company in Qatar, where he shifted from oil-linked projects to social infrastructure. He worked on public school and kindergarten construction for Ashghal, Qatar’s Public Works Authority. His role was to ensure that procurement processes aligned with international standards.
The projects may have been smaller in dollar terms, but they offered a vital perspective. “Working on community infrastructure helped me appreciate how construction affects everyday life,” he says. “You are not just delivering buildings. You are shaping the environment where children will learn, where families will gather. That realization deepened my respect for this profession.”
Still, Adeolu was hungry for larger challenges. When an opportunity came in 2014 to join Medgulf Construction Company, one of Qatar’s top-tier contractors, he seized it. The move would bring him face-to-face with the world of oil and gas mega projects.
Stepping Into Oil and Gas
Oil and gas construction is a world of its own. The projects are vast, often stretching across years and involving budgets that rival the GDP of small countries. They combine technical complexity with geopolitical importance. Cost mismanagement is not an option.
At Medgulf, Adeolu was thrown into the deep end. He worked on projects tied to Qatar Gas and Qatar Petroleum, including the North Field Expansion and North Field South developments which were central to Qatar’s strategy of increasing LNG production capacity.
His role was Quantity Surveying and Cost Control (Pre-Contract), a position that placed him at the heart of project feasibility and risk analysis. He prepared cost estimates, analyzed tenders, scrutinized contractor claims, and drafted variation orders. A single error could mean millions of dollars in exposure.
“Oil and gas projects are unforgiving,” he says, his tone more serious now. “One variation order is not just a line item. It can determine whether a project stays profitable or slips into loss. That weight of responsibility forces you to be meticulous.”
Mastering the Language of Contracts
Over time, Adeolu became deeply involved in claims management and contract administration. He attended high-stakes meetings where contractors and clients debated the validity of claims, extension requests, or additional payments.
On the Flow Assurance Expansion Project in Qatar, he worked on claims documentation that helped Medgulf protect its commercial interests while avoiding disputes that could delay work. His approach was evidence-driven. “You cannot afford to argue emotionally in this field,” he explains. “Everything must be backed by data, by contract clauses, by technical records. That is how you earn respect.”
Colleagues began to notice his sharp eye for detail and his calm under pressure. To senior managers, he was no longer just a Quantity Surveyor but a contract strategist, someone capable of seeing the bigger picture.
The Human Side of Mega Projects
Yet beyond the spreadsheets and legal clauses, Adeolu emphasizes the human dimension of his work. Cost control, he says, is also about protecting relationships.
“In oil and gas, you work with engineers, project managers, suppliers, and lawyers, often from five or six different countries on the same project. Misunderstandings can easily arise. My job is not just about numbers; it is about communication. You have to explain cost implications in a way everyone understands.”
That ability to bridge cultures is part of what has sustained him in Qatar’s diverse work environment. With project teams often made up of professionals from Europe, Asia, the Middle East, and Africa, clarity and diplomacy matter as much as technical skills.
Investing in Growth
Even as he built experience, Adeolu refused to stand still. He pursued professional certifications in project management and contract administration, strengthening his credentials in an industry where formal recognition can determine career advancement.
“Continuous learning is the only way forward,” he insists. “Every project teaches you something new, but structured learning ensures you can apply those lessons more effectively.”
This hunger for growth reflects his long-term vision. Adeolu is already thinking about how to transition from specialist roles into broader leadership, influencing project strategy on a regional scale.
The Qatar Oil and Gas Boom
Adeolu’s rise cannot be separated from Qatar’s energy story. In 2017, the country lifted a twelve-year moratorium on development of its North Field, the world’s largest non-associated gas field. By 2018, plans were in motion to expand LNG production by more than 30 percent, cementing Qatar’s dominance in global energy markets.
This surge translated into an avalanche of contracts for engineering, procurement, and construction, the very ecosystem where Adeolu operates. “Being in Qatar at this moment is a privilege,” he says. “You are not just working on projects. You are contributing to a nation’s economic strategy, and by extension, to global energy security.”
African Talent on the Global Stage
Adeolu’s journey is also part of a broader narrative, the emergence of African professionals in global technical sectors. While African nations are often seen as resource suppliers, Adeolu and his peers are showing that the continent also produces talents capable of shaping projects abroad.
“It is important to change perceptions,” he argues. “Africans are not just laborers on construction sites. We are engineers, surveyors, planners, strategists. We bring skills that are valued internationally.”
His words resonate in an era when African professionals are increasingly visible in Gulf economies, where their expertise contributes to everything from stadium construction to pipeline engineering.
Asked where he sees himself in the next decade, Adeolu pauses before answering. “Leadership,” he says simply. “Not just leading a team, but shaping how projects are conceived, negotiated, and delivered. My journey has prepared me for that, step by step.”
