Effect Of Implementing Integrated Delivery On Performance Of Public Building Construction: A Case Of Mettu Town

Abstract

The construction industry is fraught with waste and inefficiencies resulting in projects often failing to meet owners’ expectations. Integrated Project Delivery is the newest project delivery system and changes the traditional roles and relationships of key project stakeholders. Through increased early collaboration it attempts to eliminate waste and deliver the highest value projects to owners. The objective of this study was to assess the effect of implementing integrated delivery on performance of public building construction. A comprehensive literature survey was carried out to develop a conceptual linkage in construction industries, practice of integrated project delivery system in construction, its implementation and its benefit on building construction projects performance. This was followed by a questionnaire survey for 10 building construction projects and semi-structured expert interviews to ascertain prevailing status of these concepts in construction projects of Oromia Region in Mettu town. Data were analyzed using statistical and content analysis respectively. The researcher used purposive sampling method to select sample respondents. And qualitative methods based on content analysis of interview data of expertise from construction projects, as well as quantitative method on account of exploratory and confirmatory factor analysis of statistical data using Suitable descriptive statistical tools was utilized to analyze the data in (SPSS) to assess sustainable construction; benefits of integrating sustainability; and impacts on construction projects. As the research result indicated that the current methods for its implementation is mainly through “Tracking accountability for reliable commitments” (RII=0.850) which was ranked as the first, that indicates the construction industry boldly use IPD for tracking of accountability of the workers of the project. Interestingly, Having those practice the stages for application of integrated project delivery system are “During Performance monitoring” (RII=0.833) was ranked the first in this collection, which indicates that the construction industry boldly use IPD on the construction stage in the construction project because all parties participate. With most significant benefits to be derived from the integrated project delivery of the industry includes Good interdisciplinary coordination, Leads to cost reduction, Project timing improves, shared contractual risk and reward, are satisfied factors. Generally from the study to have increment on the construction industry implementation of IPD by controlling factors and applying mitigation methods is best option. Since implemention of IPD systems significantly improve many aspects of the project stakeholder’s recommended to implement IPD project administration and delivery process
