Assessment Of Time And Cost Overrun On Building Projects: A Case Study On Ifa Boru Boarding School Projects

Abstract

The Study Presented Here Is About The Identification Of The Major Causes Of Construction Time And Cost Overruns For The Case Of Ifa Boru Boarding School Projects. The Relationship Between Time And Cost Overruns With Their Factors Has Also Been Formulated. Furthermore, The Framework Was Established And Mitigation Mechanisms Were Studied To Minimize The Effects Of Time And Cost Overruns On The Selected Case Study Building Projects. The Quantitative Investigation Was Conducted By Collecting Data Through A Questionnaire Survey And Interview. The Study Was Conducted Using Both Primary And Secondary Data. Clients, Contractors, Consultants, And Regulatory Authorities Are Among The Construction Sector Stakeholders Whose Samples Were Chosen Based On Their Direct Exposure To School Building Construction Operations. Both Purposive And Random Sampling Techniques Were Utilized To Pick Samples.The Method Of Identification Of Main Factors Was Based On Their Relative Importance And MeanScore That Was Determined By The Survey Conducted On Seven School Projects. Multiple Linear Regression Analysis Has Also Been Carried Out To Identify The Most Significant Causes Of Time And Cost Overruns On The Selected Case Study Buildings. The Analysis Was Done By Microsoft Excel And Spss V26. The Analysis Results Of The Survey Data Indicate That The Major Causes Of Time Overruns In The School Building Projects Are Improper Planning And Scheduling ResultingIn A Poor Judgment Of Time And Resources (Ms=4.05) And Delay In Mobilization (Ms=3.94) From The Contractor Side, The Degree Of Interference (Ms=4.11) And Additional Work Requirements (Ms=4.07) Of The Client, Absence Of The Consultants On Sites (Ms=4.17) And Design Mistakes And Errors (Ms=4.06) From The Consultant Side And Delay In Obtaining Permits And Payment Approvals By The Construction Authorities From Causes Related To Government And Construction Authorities Are Some Of The Main Causes Of These Issues. Poor Site Management (Ms=4.02) And Shortage Of Materials On The Site (Ms=3.93) From The Contractor-Related Side, Global Financial Crisis (Ms=3.47) From The Economic Conditions Category, Delay In Obtaining Permits And Payment Approvals From The Construction Authorities(Ms=3.81) From The Government And Construction Authorities Related Delay, Poor Procurement Program Of Material (Ms=4.06) And Change In Material Prices (Ms=3.94) From Material Related Category Are The Most Frequently Rated Factors That Cause Construction Cost Overruns In The Case Studied School Building Projects. Planning And Developing A Project Master Program, Managing And Completing The Design Stage Before Construction, Procurement Management, And Setting A Clear Scope Are Some Of The Resolution Methods Identified In This Study
