At present, in the Bangkok Metropolitan Area of Thailand, numerous construction projects are in process or have recently been brought to completion. In pursuing this work, contractors regularly face construction delay problems, many of which are likely to have been avoidable. The research objective is to survey and prioritize the factors leading to construction delays from the perspective of both the consultants and the contractors. Data were collected via a survey instrument and the Delphi technique was used as the research methodology. To identify the factors that lead to construction delays relevant to the study context, a panel of experts comprising 18 construction public company leaders and 17 project engineers and 17 project consultants, 1 from each of the largest construction contractor and consultant companies in Thailand, and 20 academics in the field of construction were invited to share their opinions. Eventually, 13 factors leading to construction delays were identified from the data collected from the expert panel. A questionnaire was generated using a Likert scale with a range of 1–5 based on the factors suggested by the experts’ opinions. A total of 17 respondents from the contractor companies and 17 respondents from the consultant companies responded to the questionnaire. The numeric value of the responses was computed using the Delphi technique. The responses reached constancy at the second round of data collection. According to the statistical analysis, a Shortage of qualified labor was the most important factor leading to construction delays, according to both the contractors’ and the consultants’ perspectives with a mean value of 4.65 and 4.53, respectively. Change orders made by owners were the second most important factor according to both the contractors and the consultants with a mean value of 4.24 and 4.28, respectively. In addition, insufficient financial liquidity on the part of the contractor ranked as the third most important reason according to both the contractors and the consultants with a mean value of 4.18 and 4.12, respectively. The outcomes are applicable to the causes of construction delay in the Bangkok Metropolitan Area of Thailand, but may not be applicable to other settings. A review of the literature suggests significant differences in relation to such matters as the regulatory environment, societal practices and expectations, economic considerations, the environment, technology, and religion across settings may have an impact on what causes construction delays.

使用德尔福技术确定施工延误的主要原因：泰国承包商和顾问的观点

目前，在泰国曼谷都市区，众多建设项目正在进行或近期已竣工。在开展这项工作时，承包商经常面临施工延误问题，其中许多问题可能是可以避免的。研究目标是从顾问和承包商的角度调查和优先考虑导致施工延误的因素。数据是通过调查工具收集的，德尔菲技术被用作研究方法。为了确定导致与研究背景相关的施工延误的因素，一个由 18 名建筑上市公司领导和 17 名项目工程师和 17 名项目顾问组成的专家小组，分别来自泰国最大的建筑承包商和顾问公司，并邀请了20位建筑领域的学者分享他们的观点。最终，从专家小组收集的数据中确定了导致施工延误的 13 个因素。根据专家意见建议的因素，使用李克特量表生成问卷，范围为 1-5。共有来自承包商公司的 17 名受访者和来自顾问公司的 17 名受访者回答了问卷。使用 Delphi 技术计算响应的数值。在第二轮数据收集时，反应达到稳定。根据统计分析，合格劳动力短缺是导致施工延误的最重要因素，从承包商和顾问的角度来看，平均值分别为 4.65 和 4.53，分别。根据承包商和顾问的说法，业主发出的变更单是第二重要的因素，平均值分别为 4.24 和 4.28。此外，承包商和顾问均认为承包商财务流动性不足位列第三，平均值分别为 4.18 和 4.12。结果适用于泰国曼谷都市区施工延误的原因，但可能不适用于其他环境。对文献的回顾表明，在监管环境、社会实践和期望、经济考虑、环境、技术和宗教等事项方面存在显着差异，不同环境可能会对导致施工延误的原因产生影响。根据承包商和顾问的说法，业主发出的变更单是第二重要的因素，平均值分别为 4.24 和 4.28。此外，承包商和顾问均认为承包商财务流动性不足位列第三，平均值分别为 4.18 和 4.12。结果适用于泰国曼谷都市区施工延误的原因，但可能不适用于其他环境。对文献的回顾表明，在监管环境、社会实践和期望、经济考虑、环境、技术和宗教等事项方面存在显着差异，不同环境可能会对导致施工延误的原因产生影响。根据承包商和顾问的说法，业主发出的变更单是第二重要的因素，平均值分别为 4.24 和 4.28。此外，承包商和顾问均认为承包商财务流动性不足位列第三，平均值分别为 4.18 和 4.12。结果适用于泰国曼谷都市区施工延误的原因，但可能不适用于其他环境。对文献的回顾表明，在监管环境、社会实践和期望、经济考虑、环境、技术和宗教等事项方面存在显着差异，不同环境可能会对导致施工延误的原因产生影响。
