Construction planning and execution strategies for enhancing project success on electrical construction subcontracts

Abstract

As subcontractors, electrical contractors have been facing unfavorable environments, with problems such as constrained job site areas, schedule interference, and inefficient communication with other trades. To achieve desired goals more efficiently, electrical contractors require a more systematic and effective project management strategy. The primary goal of this research is to develop continuous task strings that pair pre-construction planning (PCP) with relevant project execution (PE) tasks in order for electrical contractors to achieve significantly better performance. Incorporating several statistical analyses, the research demonstrates the effects of continuous task strings on project performance in terms of cost and schedule success. The results reveal that the levels of task string usage are significantly correlated to project success. Moreover, task strings have significant leveraged effects on project performance: project performance can be improved by stringing together related PCP and PE tasks as opposed to performing either PCP or PE task individually. The research further suggests the specific high-value task strings that significantly increase the likelihood of achieving successful project outcomes. Ultimately, by elucidating the relationship between pre-construction planning and project execution tasks, the research can help electrical contractors accomplish significantly better performance through effective project management strategies.
