Effective site supervision plays an important role in construction project delivery. This situates site supervisors in taking the responsibilities of coordinating and controlling all physical aspects of the day-to-day task in construction projects. A cross-sectional design approach was adopted by administering a well-structured questionnaire to selected built environment professionals. Descriptive statistics was performed on the data obtained and are presented on figures and tables. The data was also subjected to inferential statistics using Kruskal Wallis test to analyze the perceptions of respondents on effects of site supervision of construction works on completion time and quality respectively. The significance of the analyzed data is on identifying the effects of site supervision on project completion time and quality delivery. The analyzed data will also guide project stakeholders in selecting competent personnel in executing construction projects.
有效的现场监督在建设项目交付中起着重要作用。这使现场监督人员承担起协调和控制建设项目日常任务所有实际方面的责任。通过向选定的建筑环境专业人员发放一份结构良好的问卷，采用了横断面设计方法。对获得的数据进行了描述性统计，并以图表形式呈现。还使用Kruskal Wallis检验对数据进行了推断统计，以分别分析受访者对建筑工程现场监督对完工时间和质量的影响的看法。分析数据的意义在于确定现场监督对项目完工时间和质量交付的影响。分析后的数据还将指导项目利益相关者在执行建设项目时选择称职的人员。
