The Nigerian Meteorological Agency (NiMet) on Tuesday in Abuja advised estate developers to always consider the temperature of any soil or location before erecting buildings to avoid building collapse.
Mr. Joseph Alozie, the General Manager Climate, NiMet, said this at the 11th Abuja International Housing show.
According to Alozie, temperature and rainfall are critical meteorological parameters with variations over time that can affect building structure and strength.
“Building foundation lies in the soil, therefore the temperature of the soil is important to the stability of the building.
“Other meteorological data most relevant in building construction are temperature, rainfall, angle and intensity of sunshine, wind and soil characteristics among others,’’ he said.
He explained that rusting of foundation equipment, corrosion of metal and cracks were dependent on relative humidity of the location.
“Selection of water and corrosion-resistant materials and equipment should be recommended and factored at design stages.
“Also, rainfall amount and rain-rate are critical in the design of ceiling of buildings to control water erosion and leakages.’’
He said that present measured values were compared to long-term averages to determine anomalies and make important derivatives.
The general manger said such information could help in the selection of proper materials based on the quantity and rate of rainfall.
“For instance, materials used in Sokoto State may not be suitable to the ones used in Akwa Ibom.
“Soil temperature varies much at the top soil but reduces with depth. The stability of the pipes and tunnels depend on their point of location.
“Information and adequate analysis of the variation of the soil temperature over location is therefore very important to its sustainability.’’
The News Agency of Nigeria (NAN) reports that NiMet is a Federal Government agency with the mandate to provide meteorological services to virtually all sectors, including the built industry.
