The data presented in this article is an original data on "Investigating the role of onsite learning in the optimisation of craft gang's productivity in the construction industry". This article describes the constraints influencing craft gang's productivity and the influence of onsite learning on the blockwork craft gang's productivity. It also presented the method of data collection, using a semi-structured interview and an observation method to collect data from construction organisations. We provided statistics on the top most important constraints affecting the craft gang's productivity using 3-D Bar charts. In addition, we computed the correlation coefficients and the regression model on the influence of onsite learning on craft gang's productivity using the man-hour as the dependent variable. The relationship between blockwork inputs and cycle numbers was determined at 5% significance level. Finally, we presented data information on the application of the learning curve theory using the unit straight-line model equations and computed the learning rate of the observed craft gang's blockwork repetitive work.
本文所呈现的数据是关于“探究现场学习在优化建筑业熟练工班组生产率中的作用”的原始数据。本文描述了影响熟练工班组生产率的制约因素以及现场学习对砌砖工班组生产率的影响。它还介绍了数据收集方法,即使用半结构化访谈和观察法从建筑组织收集数据。我们用三维柱状图提供了关于影响熟练工班组生产率的最重要制约因素的统计数据。此外,我们以工时为因变量,计算了现场学习对熟练工班组生产率影响的相关系数和回归模型。在5%的显著性水平下确定了砌砖投入与循环次数之间的关系。最后,我们使用单位直线模型方程展示了学习曲线理论应用的数据信息,并计算了观察到的熟练工班组砌砖重复性工作的学习率。
