The purpose of this study was to analyze the supply chain integration factors on thernperformance of the construction material producers with the supply of Addis Ababarnhousing project. The supply chain integration concepts were summarized on therninformation integration, internal integration, collaboration, quality of product and leadrntime of production. By considering these concepts the researcher performed the study ofrnsupply chain integration on the performance of production of construction materials inrnSME in thermo site project. The study uses descriptive and explanatory research designs asrnwell as quantitative research approach were engaged in conducting the study. The studyrnused the sampling techniques of stratified random sampling and from the total populationrnsize of one hundred eighty eight enterprises on the site. The researcher used the sample ofrnone hundred twenty eight enterprises which represent the seventy two for construction andrnfifty six for manufacturing enterprises. From the total of 128 questionnaire distributed tornthe enterprise 122 was filling and returned. By using SPSS software the supply chainrnperformance expressed by mean and standard deviation as well as correlation andrnregression analysis was made. The result of the study showed there is a high correlationrnbetween all variables and the relationship between the dependent and independent variablernwas positive except that of lead time of production. With this result the researcher concludernthat information sharing, internal integration and quality of product have positive andrnsignificant effect on the supply chain performance but collaboration and lead time ofrnproduction have positive effect on the performance of construction material producersrnrather not significant roll. Based on the findings the following issues are recommendedrnenterprises and housing project built simple computerized mechanizes like telegram,rnWhatâ€™s-App mobile application in order to effective information sharing. More over futurernstudies will consider other variables not included in this research as well as all enterprisesrnfound in the city.
