Causes and effects of delays in Malaysian construction industry

This introductory text on the design and analysis of sample surveys emphasizes the practical aspects of survey problems. It begins with brief chapters on the role of sample surveys in the modern world. Thereafter, each chapter introduces a sample survey design or estimation procedure by describing the pertinent practical problem. The authors describe the methodology proposed for solving the problem and provide the details of the estimation procedure, including a compact presentation of the formulas needed to complete the analysis. Then, a practical example is worked out in complete detail. At the end of each chapter, a wealth of exercises gives students ample opportunity to practice the techniques and stretch their grasp of ideas.

A comparative study of causes of time overruns in Hong Kong construction projects

Causes of construction delay: traditional contracts

The present paper outlines the main causes of delay in large building projects in Saudi Arabia and their relative importance. A survey of a randomly selected sample of 24 contractors, 15 architectural/engineering firms (A/E) and nine owners from the Eastern Province of Saudi Arabia was undertaken. The survey included 56 causes of delay, and the respondents were asked to indicate their degree of importance. The delay factors were grouped into nine major groups. The level of importance of the causes and the groups were measured and ranked by their importance index for contractors, owners and A/Es. It was found that contractors, A/Es, and owners generally agree on the ranking of the individual delay factors. It was also shown that contractors and A/Es substantially agree on the ranking of the groups of delay factors, whereas contractors and owners, and A/Es and owners do not agree. It was also shown that the financing group of delay factors was ranked the highest by all three parties and that environment was ranked the lowest.

Causes of Delay in Large Building Construction Projects

In Saudi Arabia as well as in other countries, building owners often differ in their approach to evaluating the work performance of their maintenance contractors. To unify the approach for such evaluation, the intent of this paper is to assess the evaluation approaches used by a variety of building owners and then focus on the main criteria used for the evaluation. To achieve this objective, this study is divided into two phases. The first phase includes a review of literature on the main criteria that can be used to evaluate maintenance contracts, followed by interviews with building owners and maintenance contractors to modify and update the criteria obtained from this review. The result of this phase is grouped into eight major categories. Each category involves a detailed list of the criteria used for the evaluation. The main categories include providing proper planning and scheduling; procuring materials for the site; providing suggestions on cost cutting; providing safety precautions at the building...

Assessment of Work Performance of Maintenance Contractors in Saudi Arabia

Outlines the defects and faults during the design stage that affect building maintenance in Saudi Arabia and their relative degree of importance. Performed a survey of a randomly selected sample of 90 contractors, 30 architectural/engineering firms (A/Es), and 20 owners from the Eastern Province of Saudi Arabia. The survey included 35 defects and the respondents were asked to indicate their degree of importance. The defects were grouped into six groups. The level of importance of the defects and the groups were measured and ranked by their severity index for contractors, owners and A/Es. The following results were obtained: contractors, A/Es and owners generally agree on the ranking of the individual defects; contractors and A/Es agree on the ranking of the defect groups whereas contractors and owners, A/Es and owners do not agree; the construction drawings group of defects was ranked highly by all three parties whereas the architectural design group of defects received a low ranking.
