Most of the construction projects with foreign investment capital have been designed and built by foreign firms but the actual subcontracting work have been performed by Vietnamese contractors.

to express my deep appreciation to The Government of Switzerland for providing financial support for my study at AIT I would like to specially express my thanks to all of my friends at SOM for their support and encouragement ii ABSTRACT Quality of Mechanical and Electrical (M&E) construction works are one of the major concerns of Vietnamese contractors as the construction industry grows This research aims to identify and validate the factors affecting project’s quality performance and their relative contribution Attempts were made to suggest practical recommendations from M&E contractor viewpoint This study involved participation of key M&E professionals, who provided objective information and their perception about various aspects of project quality and its influencing factors Multivariate statistical techniques-factor analysis and canonical correlation analysis- are employed to account simultaneously for the multi-attribute nature of the project’s quality performance and for the multitude of managerial factors Among the identified factors, those found to be mostly affecting the quality performance, by order of importance, are: 1) Authority requirement and standard used in the projects; 2) Internal quality assurance system; 3) Project team’s technical competence and communication among team members and 4) Parent organization reputation and past experience Improvement in the aspects of activities specified in these factors make it possible to improve construction quality in Vietnam iii TABLE OF CONTENT Chapter Title Page TITLE PAGE i ACKNOWLEDGEMENT ii

industry of Vietnam has contributed a great part to the national economic development during the last decade Vietnam is in a state of transition from a centrally plannedcommand economy to a market-oriented economy But, the country is in need of extensive rehabilitation and upgrading of its transportation, communications and utility systems In addition, Vietnam certainly needs an appropriate system of social infrastructure, including housing, healthcare, and education facilities Most of the construction projects with foreign investment capital have been designed and built by foreign firms but the actual subcontracting work have been performed by Vietnamese contractors Local competitors are numerous, but are facing long-term difficulties concerning insufficient capital, technology and equipment, marketing and management expertise Rivals from other countries like Japan, South Korea, Australia and France have solid positions in the Vietnamese market owing to their early arrival in the market, their technical and managerial excellence, and more importantly their home country contribution to the inflows of ODA and Foreign Direct Investment into the country In the modern construction market, quality management is a major management function in a construction organization Mechanical and electrical (M&E) works are an integral part of a construction project and their quality performance has been greatly affecting the overall project quality The local M&E contractors face problems with different systems of standards being used and the shortcomings of project management skills The quality of M&E projects therefore is one of major concerns for managers working in this field Like many developing countries, Vietnam has been relying completely on the methods and techniques concerning quality that were initiated and developed from outside These quality systems may not be well adapted to suit the economic, political, social and technological environment of Vietnam Thus, determining the M&E construction industry’s viewpoint on the factors that would improve construction quality performance is an essential step toward establishing methods for real improvement of construction quality in Vietnam Understanding the main factors affecting quality of M&E projects will help M&E companies improve quality of their work and increase overall competitiveness 1.1 Objectives of the Research 1.1.1 General objectives The main objective of this research study is to identify and validate the major factors, which mostly affect the quality performance of M&E works and the relative importance of these factors in construction projects The factors being identified would help to improve quality and the effectiveness of project management in M&E projects 1.1.2 Specific objectives The following research objectives are to be completed: • Review of the construction development and FDI construction in Vietnam to have an overall picture about the industry • Overview of a construction project and its activities; define the role of M&E work in construction projects and relevance of this research • Determining project quality performance, critical success factors definition and measures in projects and particularly for construction projects through extensive literature review • Define the project quality and its measures, factors affecting project quality and their measures • Determining major factors and their relative importance by analyzing data from survey questionnaires • Derive practical implications of obtained results 1.2 Scope and Limitations of the Research This research focuses on the operational quality of M&E project management team and from the prospective of M&E contractors during the construction and maintenance phases of construction projects The survey is conducted among project managers or project engineers of major M&E companies in Ho Chi Minh City but the projects mentioned in the responses may be from other provinces as well Due to time and resources constraints, the limitations of this research are: • Surveyed projects are limited to FDI or with projects with element of foreign funding • Relatively small list of variables might not account for all effects upon performance • M&E projects have specific features therefore the research results might not be applicable for other types of project • Local socio-economical conditions and technological level limit the expandability of the model to other countries • Performance success has to be considered together with cost and time in an overall context for project success assessment since they are inter-related 1.3 Organisation of the Research This research is organized into seven chapters as outlined below: Chapter 1: Introduction This chapter explains the rationale, objectives, scope and limitation of the study Chapter 2: Overview of the Construction Industry in Vietnam Based on secondary data, this chapter presents an overview of construction industry in Vietnam and FDI construction, the need to bring international construction standards to Vietnam Chapter 3: Project Activities and M&E Work This chapter gives description of typical activities and role, characteristics of M&E work in a construction project The relevance of this research is also explained in details Chapter 4: Literature Review This chapter presents a literature review of project quality definitions and measures, ways to assess critical success factors of a project in general and a construction project, in particular Chapter 5: Research Methodology Based on literature review, a method will be developed to assess the factors that influence the quality performance of M&E construction projects Basic concepts of statistical tools to be used are also explained in this chapter Chapter 6: Findings of the Study This chapter presents the findings based on the results of a survey conducted in Ho Chi Minh City Statistical analysis is applied to show the relative importance of various factors on project quality performance Chapter 7: Conclusions and Recommendations Based on the findings, this chapter will present some conclusions and recommendations thought to be of importance to M&E project management tasks REFERENCE “Benefits of Quality Design and Construction” Manual of Professional Practice Quality in the Construction
