Effective construction scheduling is crucial for the success of road projects. However, deficiencies in this scheduling can lead to significant challenges such as delays, cost overruns, and litigation. Therefore, project managers need to understand the causes that contribute to these deficiencies thoroughly. Unfortunately, there has been little research examining these elements in detail. To address this gap, this study examined the causes that affect the scheduling of construction processes for road projects. The research method involved four stages: (1) identification of causes affecting construction scheduling, (2) design and application of a questionnaire, (3) influence analysis, and (4) exploratory quantitative analysis. The study identified 34 causes of deficiencies in the scheduling of road construction processes in six categories: workforce, machinery, material, measurement, environment, and method. Thirty-two experts were consulted to evaluate the frequency and severity of each cause based on a relative influence index. The causes with the greatest impact on deficiencies in road construction scheduling were poor estimation of labor performance, poor estimation of workforce quantity, and deficient coordination with public utilities. The findings allow managers to pinpoint the root causes of road construction planning problems and identify effective solutions.
有效的施工进度计划对道路项目的成功至关重要。然而，这种进度计划中的缺陷可能会导致重大挑战，如延误、成本超支和诉讼。因此，项目经理需要彻底了解导致这些缺陷的原因。不幸的是，很少有研究详细考察这些因素。为了填补这一空白，本研究考察了影响道路项目施工进度安排的原因。研究方法包括四个阶段：(1) 确定影响施工进度的原因；(2) 设计并应用一份调查问卷；(3) 影响分析；(4) 探索性定量分析。该研究确定了道路施工过程进度计划缺陷的34个原因，分为六类：劳动力、机械、材料、测量、环境和方法。咨询了32位专家，根据相对影响指数评估每个原因的频率和严重程度。对道路施工进度计划缺陷影响最大的原因是对劳动绩效估计不足、对劳动力数量估计不足以及与公用事业协调不足。这些研究结果使管理人员能够查明道路建设规划问题的根本原因，并确定有效的解决方案。
