The construction industry is labour intensive, and hence, skill development of the industry would yield both economic and social returns to the national economy. Among other occupational categories, plant and equipment (P&E) operators in the construction industry have significant importance since the skills and competencies of P&E operators are necessary to be well equipped to serve the higher demand and technological trends. Nevertheless, the available research in the said area is limited. Hence, this study aims to analyse the skill gaps of P&E operators in the perspective of construction professionals in Sri Lankan building construction projects. The study analysed the level of importance and level of satisfaction of P&E operators in the perspective of construction professionals. The research was designed with a quantitative research approach with a questionnaire survey administered among construction professionals with a response rate of 73%. The quantitative analysis depicted that maintenance skills of P&E operators have the highest level of satisfaction by construction professionals with more than 3.77 of mean weighted rating (MWR) and importance with over 3.87 of MWR in the industry. The smartness of handling machines and teamwork were identified as the next two essential and satisfied skills of P&E operators in each category. Out of sixteen skills identified, analytical, mechanical, innovative, and interpersonal skills show a slight skills gap among different categories of P&E operators. Compared to other skills, IT received less importance under each P & E category. Furthermore, the study has concluded the skill gaps in the categories of P&E operators in the Sri Lankan building construction industry. Having identified the gaps, the paper provides the means of measurement to present, which are the most identifiable skills gap of P&E operators in the building construction projects. Propose strategies to enhance the skills of P&E operators to overcome existing issues in the Sri Lankan building construction industry and investigate the skill gap of P&E operators in infrastructure projects can be highlighted as further research areas.

The construction industry, which is a labour intensive and skill development of the industry would yield both economic and social returns to the national economy. Among other occupational categories, there is a significant demand for the plant and equipment (P&E) operators in the construction industry. Nevertheless, limited numbers of research are available on the said area. Hence, the aim of this paper is to investigate the status of P&E operators in Sri Lankan building construction projects. Accordingly, this study encompassed a qualitative research approach, and six semi-structured expert interviews were conducted as the data collection tool. The study revealed that mainly two categories of P&E as moveable and immovable and further identified subcategories under each. Based on the results, occupational map was developed for the P&E operators in building construction projects in Sri Lanka. Furthermore, the study revealed that technical and mechanical skills as an essential input for an efficient P& E operator. Moreover, the paper discussed issues with P & E operators. Accordingly, inconsistency, taking long leave, poor health conditions, less experience, and less motivation were identified as prominent issues.

A hydraulic excavator is widely used in crushed stone quarries to perform many different operations. Previous research on material handling by excavators is most often based on laboratory testing and observation of soil materials and the digging forces in them. These results are very difficult to transfer to fieldwork during the quarrying process. Therefore, in this work, the energy consumption of an excavator while working in typical materials for a crushed stone quarry was investigated. The field measurements were performed on overburden, blasted rock material, boulders, and two different crushed materials. Energy consumption was observed only during the portion of the cycle in which the bucket digs the material. In this way, the energy consumption was mainly related to the properties of the material. The highest energy consumption was found for blasted rock material, lower in overburden, and the lowest for boulders and crushed materials. These results are important for organizing an optimal distribution of machines according to the work tasks in the quarry and ultimately for energy savings.
