The construction sector in Nigeria has a big impact on the country's economy, but faces challenges like relying too much on foreign materials and struggling with project costs and timelines. A study looked at 47 years of data to see how construction affects the GDP. They found that the construction sector does affect the GDP, but only when previous GDP levels aren't included in the analysis. Overall, the connection between construction and GDP isn't very strong. The study suggests creating new policies for housing and transportation to improve Nigeria's infrastructure.
