Determinants of Time Overrun in Small Construction Projects: evidence from Brazil

This database was colected to test a theoretical model of Determinants of Time Overrun in Small Construction Projects, through exploratory factor analysis. The data was gahered from a survey with 106 professionals. TOur results pointed out the significant differences in causes of time overruns between small and larger construction projects, especially concerning the scope and quality of design, manpower, and materials. These results indicate that companies performing small construction projects are less professionalized and structured than larger companies, facing even more challenges in meeting time schedules. The comprehension of the mode and nature of each determinant can lead professionals and academics to design methods and techniques aimed at growing efficiency in construction projects that could reduce time overruns in the construction industry. To the best of our knowledge, this is the first study in Brazil to address the wide range of causes of delays in small construction projects from a structured quantitative approach.

本数据库旨在通过探索性因素分析测试小型建设项目时间延误决定因素的理论模型。数据来源于对106位专业人士的调查。我们的研究结果表明，小型与大型建设项目在时间延误的原因上存在显著差异，尤其是在设计范围与质量、人力和材料方面。这些结果指出，执行小型建设项目的公司在专业化和结构化方面不如大型公司，面临满足时间安排的更大挑战。对每个决定因素的模式和本质的理解，可引导专业人士和学者设计旨在提高建设项目效率的方法和技术，从而减少建筑行业中的时间延误。据我们所知，这是巴西首次采用结构化定量方法全面研究小型建设项目延误原因的研究。
