INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Construction and engineering practitioners have found it increasingly difficult to learn from their mistakes, particularly with regard to the prevention, identification and/or containment of design errors. John. et al, (2001) explained that majority of structural failures and associated damage costs are due to errors in planning, design, construction, and utilization, rather than variability in construction material, strengths and structural loads. It should be recall that design is the first stage of construction and design errors have been the root cause of numerous catastrophic accidents that have resulted in the death and injury of workers and members of the public.
The owner, designer and contractor all have different interests in, or uses for the design of a facility. But what they do share is the commitment to complete the project safely and within a given budget and completion time. There are many initiatives being conducted to control the growth of Initial Cost and schedule within the construction industry.
The major issue is "accuracy of the drawings," or the number of design errors, omissions and ambiguities within the plans and specifications that affect the quality of the facility. Inadequacies in the plans and specifications are the major causes of changes to the contract So much emphasis is placed on the issue of time and Initial Cost that quality takes a back seat .The quality of the project depends on the conformance of the objectives and requirements from the owner. An informative quality management technique will provide an agreement to procedures and definitions among the principle parties for the project. Since design errors have an impact on the outcome of the effectiveness of the contractor's effort on the project it is essential that all parties determine what the definition of a design error should be.
