Analysing the Physical Condition of Buildings: A Case Study of an Institution of Learning in Nigeria
(School of Environmental Technology International Conference Proceedings (SETIC 2024), 2024) Abass, A.; OGUNBODE Ezekiel Babatunde; Olubajo, O. O.
Abstract Buildings depreciate with time and gradually perform less than they are expected. This is a concern for building owners and users. Research on depreciation of building tends to focus on identifying or categorising defects. However, investigations that examine the condition of public buildings that inhabit large and frequent users is limited. The aim of this research is to analyse the physical condition of public buildings in an institution of learning. This study adopts a case study approach involving physical observations and the condition rating of three buildings in an institution of learning in Nigeria. The results of the analysis showed that there were several similar defects on the walls, floors, roof, electrical and mechanical services. The results on the condition of the buildings showed average condition index values indicating that the buildings were in moderate condition with the laboratory in a better condition with an average condition rating of 0.58 and the offices with an average condition rating of 0.52 and the classes with an average condition rating of 0.44. The study argues that improving the condition or state of the buildings would lead to enhanced building performance.
Analysis And Prediction Of Cost And Time Overrun Of Millennium Development Goals (MDGS) Construction Projects In Nigeria.
(Developing Country Studies, 2012) Edoka Augustine Ijigah; OGUNBODE Ezekiel Babatunde; Moshood O. Ibrahim
Abstract The paper focuses on the analysis and forecast of cost and time overrun of MDGs construction projects in Nigeria. Twenty five MDGs construction projects from (2006-2009) were critically investigated and time and cost overrun of the project were studied. The Statistical Package for Social Scientists (SPSS) 19.0 version was used to analyse the variables using Paired t-test and simple regression at 95% confidence limits. The analysis was based on the adaptation of requisition method. The validity test on the efficiency of the model was highlighted using the confidence interval to enhance the application of the models. Mathematical models were developed. The findings shows that there is a significant different between the total contract sum, cost overrun, total contract duration, and time overrun for the MDGS projects. The study suggests acute need for government to engage in proactive strategic planning and approaches to keep construction project cost and time within reasonable limit for the actualization of MDGs policy of development and environmental sustainability.
Effect of Age on the Structural Strength of Timbers Commonly Used in Nigeria
(Environmental Technology and Science Journal, 2024) OJO Segun Olaniyi; OGUNBODE Ezekiel Babatunde; MAKUN Christopher Sunday; EKEKEZIE C. U.; ABDUL Aliyu
Timber is a material used for structural purposes in construction. Hence, the knowledge of properties of timber especially strength and factor affecting the strength of timber is very important. Age of timber is one major factor affecting timber strength and timber was usually fetched without knowledge of whether the timber is matured to meet the structural strength required. Therefore, this research tends to evalutate the effect of age on the strength of some selected timber species so that forester and users likewise could be guided on when to deforest. In this study, timbers studied were Universitas Orientalis Kentuckiensis (Eku), Entandrophragma cylindricum (Sapele) and Gmelina Arborea (Melina). The age of timber was determined by counting the number of annual growth rings, which is the combination of early wood and late wood and samples of different ages of timber, were obtained by personal visit to forest where they were fetched freshly. The samples obtained were machined and trimmed to standard sizes according to BS 5268 pt2 2003. The compressive strength was done using a timber size of 20mm X 20mm X 60mm, 20mm X 20mm X 300mm for determination of the bending strength and shear was performed using 20mm X 20mm X 20mm timbers (all in three replicate). The maximum compressive strength values were 49.31kN/m2 (at 45years), 45.89kN/m2 (at 60years) and 11.30kN/m2 (at 25years) for Eku, Sapele and Melina while the maximum bending strength were 187.55kN/m2 (at 35years), 278.79kN/m2 (at 70years) and 176.36kN/m2 (at 20years) and shear strength were 10.05kN/m2 (at 50years), 9.22kN/m2 (at 70years) and 10.91kN/m2 (at 25years) for the for the three samples. It was concluded that age of timber affects the strength of timber.
