“…2. The remit of the present study has purposely avoided influences on mechanical and machinespecific technical factors that could also influence productivity, such as the man-machine interface (Ha et al, 2000) and methods of machine control (LeBlond et al, 1998). Future research may also need to take account of these aspects as appropriate.…”

Purpose – Excavator productivity calculations embrace myriad variables, which in turn, can be modelled in several ways. A key productivity variable is operator competence (O c ) because this can impact on so many of the other variables. Earlier research has studied excavator productivity, but little has attempted to simultaneously model productivity variables in relation to O c . The purpose of this paper is to address the void in extant literature. Design/methodology/approach – A numeric, theoretical analysis is undertaken using the Caterpillar® hydraulic excavator productivity model to estimate excavator production, given: first, variance in modifying factors based on derived maximum and minimum values; and second, variance resulting from linear calculations based on excavator operator competence. Findings – Excavator productivity resulting from incremental variance of modifying factors in isolation is shown to be linear except, in the case of bucket payload. Simultaneous application of modifying variables results in a greater, curvilinear productivity trend; while it is demonstrated that quantification of key modifying factors can to a significant extent be related to operator competence. Research limitations/implications – Findings add to productivity literature generally and to that of plant and equipment more specifically. Results will help productivity estimation of excavation in a practical sense while informing subsequent design of an empirical academic research of this problem. Originality/value – Originality relates principally to determining modifying factor ranges and their analysis of simultaneous effect on each other, especially, as influenced on assumptions of operator competence.

“…Different controls of machines concerns with the improving and also controlling the plant, tools and equipment. LeBlond et al (1998) mentioned that if the plant would be controlled well the safety issues of the project would be assured and also productivity of the project would be increased dramatically. To this aim computer aided controlling can improve the construction site activities very well.…”

During the recent years different people in charge have been considered about different costs of the plants in the construction industry. Usually it seems to be a big challenge for different people in charge and mainly contractors to decrease the costs of the projects through the optimum use of construction plants in order to increase the quality of the project and decrease time and cost. During the current study, researchers have been investigated about the construction plant use in the construction sites and also its effect on the quality and also time of the project. Forty three people in charge with the construction projects have been participated in the current survey. After analyzing the required data through SPSS software and based on the mean index of the scores five items have been identified as the most important issues in the construction management regarding the use if plants namely: The effect of spare parts availability to decrease downtime, the effect of employing expert mechanics to increase the repair quality, impact of gasoline and petrol availability to decrease wasting the time, impact of periodic control and serviceability of plants and equipment to increase productivity, impact of training persons who are involved plants and equipment to increase productivity. It goes without saying that extracted factors have significant role in the construction projects and different contractors should consider them in their projects.

“…via information) the control of plant and equipment. LeBlond et al (1998) in their paper on control improvement for advanced construction equipment, stated that better control can lead to improvements in safety, cost, labour turnover and productivity -going on to suggest -that computer enhanced manual control is favourable to autonomous control in a typical construction environment.…”

PurposeA literature review is presented in the subject of construction plant and equipment management (CPeM) to: delineate the subject; consider its development over recent years; and identify principal themes within it. The paper aims to close the gap in knowledge, by using these objectives as a mechanism to observe how research themes relate to primary CPeM functions, and to suggest future research direction.Design/methodology/approachA thematic review of CPeM academic literature (in the main, refereed journal papers published in English‐speaking countries over the last decade) is undertaken; the nature of identified themes is discussed, for instance, regarding why they might have evolved as they have; and based on the foregone, themes for future research in the field are proffered.FindingsCPeM is found well established within the broader subject of construction management. Eight principal themes are identified, namely plant maintenance; downtime and productivity; optimisation; robotics and automation; health and safety; operators and competence; machine control; and “miscellaneous”.Research limitations/implicationsIt is proffered that based on informational/technological advancements coupled with growing environmental/financial pressures, future CPeM research will strive to facilitate even greater plant reliability and safer modes of working. It is suggested that “optimum production methods” and “minimal resource consumption” will become inherent theme goals.Originality/valueThis is the first time that CPeM research has been consolidated and reviewed for publication in this manner.
