Thesis Abstract

Abstract
Quality assurance is a crucial aspect of project execution, especially in the construction industry. This study aims to investigate the effectiveness of quality assurance strategies in project execution, focusing on road construction projects in Owerri. The research will adopt a mixed-method approach, combining quantitative analysis of project performance data and qualitative interviews with key project stakeholders. The study will evaluate the current quality assurance strategies employed in road construction projects in Owerri and assess their impact on project outcomes. By analyzing data on project completion times, budget adherence, and quality of road infrastructure, the research aims to identify the strengths and weaknesses of existing quality assurance practices. In addition, the study will explore the perceptions of project stakeholders, including project managers, engineers, contractors, and government officials, regarding the effectiveness of quality assurance strategies in ensuring project success. Through in-depth interviews and surveys, the research will gather insights on the challenges faced in implementing quality assurance measures and the perceived benefits of these strategies. Furthermore, the study will compare the actual project performance with the intended project goals and specifications to determine the extent to which quality assurance practices contribute to project success. By examining case studies of completed road construction projects in Owerri, the research will provide practical examples of how quality assurance strategies have influenced project outcomes. The findings of this study are expected to contribute to the body of knowledge on project management and quality assurance in the construction industry. The research will offer recommendations for improving the effectiveness of quality assurance strategies in road construction projects, with implications for enhancing overall project performance and stakeholder satisfaction. Ultimately, this research seeks to highlight the importance of robust quality assurance practices in project execution and provide insights that can guide future project management decisions in the road construction sector in Owerri. By identifying best practices and areas for improvement in quality assurance, the study aims to enhance the efficiency and effectiveness of project delivery, ultimately benefiting the local community and economy.

Thesis Overview

1.1 Background Of The Study

Over the years, most projects in organizations especially those of the Zerock, Rhas and New Idea Construction companies in Owerri, might have been subjected to poor performance and abandonment following the inability of the management of such projects to apply quality assurance techniques in the execution of such projects.

According to Jaideep (2009), the definition of quality varies in different contexts. On one hand, we talk of software quality that means adopting standards and measures to ensure the building of software product that meets all customer requirements (design, interface, business requirements, functional requirements, etc) and ready to deliver. On the other, hand, project quality refers to the standard and measures by means of building (or adopting) to ensure successful completion of a project, in terms of time and revenue. This starts right from initiation of the project to its implementation stage and continues to the post implementation stage. In the context of software-the quality means software strategy, plan, test cases, test scenarios, test results and fixing of bugs. Inclusion of quality in this context will vary from organization to organization and project to project (within an organization). This will ensure the successful building of software product ready for delivery. In the context of project, the quality would mean managing quality standards and measures for a project right from its initiation to all stages coming forth. A project life cycle in standard terms would comprise of project initiation, project planning, development execution, implementation, execution, project close-out, and post implementation phase broadly, which remains on-going till the software built is in use by the customers for a period of years (Jaideep, 2009).

Also, according to the project management book of knowledge PMBOK (2005), to perform quality assurance means applying-the planned, systematic quality activities to ensure that the project employs all processes needed to meet requirements. Quality assurance is the application of planned systematic quality activities to ensure that the project will employ all processes needed to meet requirements. Quality assurance is the application of planned systematic quality activities to ensure that the project will employ all processes needed to meet requirements (PMBOK, 2005). A quality assurance department or similar organization often oversees quality assurance activities. Quality assurance supports, regardless of the unit’s title, may be provided to the project team, the management of the performing organization, the customer or sponsor, as well as other stakeholders not actively involved in the work of the project. Quality assurance also provides an umbrella for another important quality activity, continuous process improvement. Continuous process improvement provides an iterative means for improving the quality of all processes (PMBOK, 2005). Such quality assurance inputs as quality management plan, quality metrics, process improvement plan, work performance information, approved change requests, quality control measurement, implemented change requests, implemented corrective actions, implemented defect repair and implemented preventive action must be performed (Anyanwu, 2007).

1.2 Statement Of The Problem

Many construction industries in Owerri had in the past delivered completed construction projects which fell short of design specifications and quality standard. (Ministry of Works, Owerri, 2012).

Indeed, most of the roads hardly survived one rainy season. Many roads constructed in the past lack durability and reliability in that they cannot withstand the climatic and environmental challenges in Owerri. Examples of such roads include St. Johns Laboratory through Relief Market to Egbu road and Transfiguration road between IMSU Junction and MCC road junction.

Experience has also shown that many project managers find it difficult to determine if quality assurance is effective for successful project execution in construction industries (Anyanwu 2007). It could also be dangerous for project completion if there are low performance indices due to inability to put in place quality assurance techniques in project construction.

It is also painful, as experience has shown that many project managers are yet to develop a relationship between quality audit and input materials in construction firms. This could be compounded by the perceived poor attitude of project firms to quality assurance techniques (Kenny, 2010).

It is in the light of the above problems that this research is conducted.

1.3 Objectives Of The Study

The major objective of this study is to determine the effectiveness of quality assurance strategies on the execution and delivery of construction project. Specifically, this study is undertaken to:

(a) Determine if quality assurance is effective for successful project execution in the construction industries.

(b) Examine the performance indices for quality assurance in

construction projects.

(c) Determine the extent of application of quality audit to input materials in construction firms.

1.4 Research Questions

The research questions for this research work are:

(a) Are quality assurance strategies effective for successful project execution in construction industries?

(b) Are there performance indices for quality assurance in project construction?

(c) Is there any relationship between quality audit and input materials in construction industries?

1.6 SIGNIFICANCE OF THE STUDY

Project managers will use this work to determine the essential roles which quality assurance can play in the satisfaction of project owners. Project workers will use this work to understand the need to improve their quality assurance skills. Project management

consultants and project-based firms will use this work to educate their clients on quality assurance and improve the quality of their works respectively.

1.7 Scope And Delimitation Of The Study

This study seeks to investigate the effectiveness of quality assurance in project execution as it affects all projects in various organizations, but due to time and financial constraints, the researcher has chosen to focus on project organizations like Zerock, Rhas and New Idea Construction Companies.

It is not only quality assurance that has effects on project execution, other factors like time management, motivation, project human resources development and project financial management all have impacts and effects on project execution.

1.8 Limitations Of The Study

There were a lot of constraints which the researcher

encountered in the course of carrying out this research work. First, was the lack of sufficient funds to face the challenges of the research work. This was overcome by the intervention of relatives. It was difficult to educate the respondents on how best to complete the questionnaires administered to them. The researcher solved this problem by ensuring that the respondents filled the questionnaires in her presence.
