The project cost overruns instigated through the loss of construction materials lowers the profitability of each stakeholder significantly. The purpose of this single case study was to explore strategies managerial leaders of a large construction firm used to counteract material cost overruns successfully. The diffusion of innovation theory was the conceptual framework for this study. The target population consisted of 6 managerial leaders with experience in large construction projects adhering to waste management standards and industry certifications. Data were collected using semistructured interviews and review of company documentation. The data analysis approach involved the content analysis research method to interpret and code the verbatim transcriptions of interviews into categories. The 2 principal categories from the study data were material management and planning and the supply chain and logistics. The results of the study yielded evidence of 2 strategies to counteract the material cost overruns, which were to strengthen partnerships with the suppliers and to hold regular audits at the project sites. The implication of this study for social change includes the potential to conserve depleted land minerals and valuable land reserves from becoming landfill by providing construction managers with information about strategies to counteract material cost overruns.
