Material Cost Optimization and Quality Control Improvement of Building Construction

A building construction project cannot be completed successfully by only planning and scheduling. Project controlling that consists of monitoring updating, is the other critical stage. Construction materials cost quality are becoming a severe problem in Ethiopia, especially Ambo Town, where little consideration given. The study tried to evaluate different factors affecting on site, rank significant prevalently used for projects from point view respondents, established model optimize using multilinear regression method come up with best fit. Purposive sampling was used, 180 questionnaires were administered firms analyze Material Optimization control Improvement- Case Study Town. To achieve this, questionnaire survey containing Building material quality, which identified literature Interview, analyzed Relative Importance Index, Pearson's correlation, Multilinear model. Variables statistically at 95% confidence level assessed all independent variables positively related quality. RII results showed Wastage minimization (RII = 0.908), Proper workmanship (RII= 0.859), Sufficient Training workers/staff 0.876), forecasting price market 0.850), Using suitable, safe secure storage 0.886), Quality checking each delivery aggregates site 0.889), Cutting ( glass, tiles, plywood) 0.870) Design changes 0.770) ranked as most among materials. Also, Two Multiple linear models both dependent (material quality). analysis had strong positive relationship variables. values R2 developed equations indicated 0.771 0.777 Hence, basic recommendations such activities inspection verification anticipated exercised key role players industry.
