Labours in construction are one of the main pillars in the construction industry of Malaysia for projects execution. Construction labours not only contributes to the development of the construction industry but also impacts the Malaysian economy. Consideration of labour wages is made in the initial phase of the project budget, however, wages are getting changed over time. The inflation rate is one of the key factors which affect labours wages. Regrettably, the inflation rate is being ignored while computing labour wages for projects budget development, resulting in cost overrun of construction projects. In this regard, the correlation coefficient test was used to determine the impact of the inflation rate on labour wages gathered from the year 2013 to 2019. The results showed that a significant acceptable relationship exists among the inflation rate and several categories of labour wages. Most of the labour wages showed a negative relationship with the inflation rate, indicating the deviation in the wages, thus, result in cost overrun. To steer the cost overrun effect, it is recommended to adopt automation system and introduce the Industrial Revolution (IR) 4.0 in construction projects as a replacer of labours.

建筑工人是马来西亚建筑业项目执行的主要支柱之一。建筑工人不仅有助于建筑业的发展，而且对马来西亚经济也有影响。在项目预算的初始阶段考虑了劳动工资，但随着时间的推移，工资会发生变化。通货膨胀率是影响劳动力工资的关键因素之一。遗憾的是，在计算项目预算制定的劳动力工资时，忽略了通货膨胀率，导致建设项目成本超支。对此，采用相关系数检验来确定2013年至2019年收集的通货膨胀率对劳动工资的影响。结果表明，通货膨胀率与几类劳动工资之间存在显着的可接受关系。大部分劳动力工资与通货膨胀率呈负相关，表明工资存在偏差，从而导致成本超支。为控制成本超支效应，建议采用自动化系统，并在建筑项目中引入工业革命 (IR) 4.0 作为劳动力的替代品。
