Analytical Roofing Crews’ Work Using Micro Scheduling for Productive Roof Replacement in Southeastern Residential Units

The roofing construction industry is based on informal communication, craftsman apprenticeship, and skills acquired from routine. This manuscript introduces research on a roof replacement procedure for a typical residential unit in South-East Georgia. This is sought for an understanding of intimacy in effective and adaptive team behavior of the construction roofing crews. The main objective of this study is to apprehend linkages between effective roofing teams and the work they perform adaptability, resilience to changing systems, and team cooperation. The study was executed by documenting the project at a micro level; breaking down the roofing crew into micro-teams, analyzing their natural group, and individual work rhythm. The researchers created an approach on production micro-scheduling, combining a repetitive line-of-balance approach, and a mathematical scheduling method for the sequence of roof replacement work. To evaluate team behavior, the study defines efficiencies in roofing tasks completed by the roofing crew. A micro-level analysis of their work has been completed in order to compute the efficiencies of workers within their micro-crews for the roof replacement project. The analysis involved the research group observing on-site activities of working crews and their work task details throughout the job. Their tasks were further analyzed via on-site video recordings and later through scheduling software to determine performances against a baseline work procedure. Development of network task scheduling for all roof areas on this jobsite illustrated the adaptability of a working crew compared with a formal crew through a baseline work procedure. Findings of crews with a well-organized hierarchy of laborers, support, and leadership within their micro-crews display optimum performance in change resiliency and cooperation; these crews are most efficient in their work due to labor distribution and effective active lag use.
