Abstract

Variation orders are common in civil engineering construction projects and serve as significant measurement tools for project efficiency and success. This study focuses on identifying the causes and impacts of variation orders in building projects. Three hotel buildings under construction in Bharatpur were considered for the study. The study population included the client, consultant, and contractor, as they are the major stakeholders in any construction project. Data were collected using a five-point Likert scale and analyzed using the Relative Importance Index (RII) to rank the causes and impacts of variation orders. The study also identified strategies to minimize variation orders. Based on the overall ranking using the RII index, the top three causes of variation orders in building projects at Bharatpur were found to be: Errors and omissions in design (RII = 0.953),Variations in the scope of work by additions, omissions, and alterations of the employer’s requirements (RII = 0.937) and Change in design and drawings by the consultant (RII = 0.905) Regarding the impacts of variation orders, the top three identified impacts were: Completion schedule delay, Increase in project cost, Affect on progress. All parties strongly agreed on the ranking of these impacts, as supported by a Kendall’s coefficient of concordance value of 0.973.Strategies to minimize variation orders: Fourteen major strategies were identified and analyzed to minimize variation orders. The top three measures, ranked based on overall RII analysis (Kendall’s coefficient of 0.812), were:Complete the drawings at the tendering stage (RII = 0.942), All involved parties should plan adequately before works start on-site (RII = 0.937) and Carry out detailed site investigation, including soil investigations, and consider them during the tendering stage (RII = 0.895)
建筑施工项目变更顺序的成因及影响——以印度巴拉特普尔地铁三个工程为例
变型单在土木工程建设项目中很常见,是衡量项目效率和成功与否的重要工具。本研究的重点是确定建筑工程中变更顺序的原因和影响。Bharatpur正在建设的三座酒店建筑被考虑用于研究。研究对象包括客户、顾问和承包商,因为他们是任何建筑项目的主要利益相关者。使用五点李克特量表收集数据,并使用相对重要性指数(RII)对变化顺序的原因和影响进行排序。该研究还确定了最小化变化顺序的策略。根据使用RII指数的总体排名,发现Bharatpur建筑项目变更订单的前三大原因是:设计中的错误和遗漏(RII = 0.953),雇主要求的增加,遗漏和更改导致工作范围的变化(RII = 0.937)和顾问设计和图纸的更改(RII = 0.905)。关于变更订单的影响,确定的前三大影响是:延迟竣工进度,增加工程成本,影响工程进度。所有各方都强烈同意这些影响的排名,肯德尔的协调系数值为0.973。最小化变型顺序的策略:确定并分析了最小化变型顺序的14个主要策略。综合RII分析(Kendall’s coefficient = 0.812),排名前三的措施分别是:投标阶段完成图纸(RII = 0.942)、施工前各方做好充分规划(RII = 0.937)、开展详细的现场调查,包括土壤调查,并在投标阶段予以考虑(RII = 0.895)。
