Abstract

Construction project delays caused by contractors and suppliers are the top problems in Thailand's oil and gas industries. Recognizing this importance and their relationships between factors can help reduce the risk of delays in construction projects. Therefore, this study set out to confirm factors and inspect relationships between delay factors of contractors and suppliers. A 16 item questionnaire survey was distributed to 134 managers, engineers, and supervisors in oil and gas platform construction projects in Thailand. A confirmatory factor analysis (CFA) was performed by the use of Amos Version 20 software program. The analysis results showed that delays caused by the contractors and suppliers had high relationships, due to high regression weighs. The delays caused by the contractors included seven factors which included poor site management and supervision (17%), lack of safety rules and regulations (16%), poor communication and coordination with others (15%), poor procurement system management (15%), defective components and mistakes during construction (14%), supplier payments lateness (13%), and poor planning and scheduling (10%). The delays caused by the suppliers included six factors which included the supply of unqualified and unskilled personnel (22%), supply of low efficiency equipment (20%), late delivery of materials and equipment (20%), supply of low quality materials (16%), late supply of workers (16%), and price escalation (5%).

Highlights

Construction project delays cast a dark shadow over many construction projects, with the most important being caused by the stakeholders
Assaf and Al-Hejji [5] conducted a site survey of 23 contractors in Saudi Arabia to determine the causes of delays, and found that 76% of the most common causes come from contractor difficulties in financing, poor site management, poor communication, poor planning and scheduling, and improper construction methods
From the use and analysis of a confirmatory factor analysis (CFA) on contractor and supplier delay factors, it was determined that there is a significant relationship between the sets of factors

Summary

Introduction

Construction project delays cast a dark shadow over many construction projects, with the most important being caused by the stakeholders. Confirmation of this has come from Fallahnejad, which reported that in many countries (including Iran), delays caused by contractors and suppliers are in the top 10 reasons for delay in the oil and gas industry [1]. Ruqaishi and Bashir [2] indicated that poor site management and contractor supervision (such as ineffective planning and scheduling) are the main causes of the oil and gas construction projects delays in Oman. In Jordan construction projects, evidence shows that contractor financial difficulties are common causes of project delays [4]. Assaf and Al-Hejji [5] conducted a site survey of 23 contractors in Saudi Arabia to determine the causes of delays, and found that 76% of the most common causes come from contractor difficulties in financing, poor site management, poor communication, poor planning and scheduling, and improper construction methods
