Previous research has indicated that in about 85% of the projects, the managers underestimated the extent of uncertainty at the start of a project. Since then limited research has been conducted to study the uncertainty climate in AEC organizations. The primary goal of this research was to assess the approaches of construction organizations towards managing uncertainty. The Working Climate Survey measured two aspects of uncertainty namely---personal and work environment uncertainty and plotted a matrix based on these scores. This matrix was equally divided into four sections namely---dynamic, unsettling, status quo, and stifling. The desirable condition is when most of the respondents are in the dynamic climate. Analysis of the responses of 61 construction industry professionals from a wide spectrum of companies indicated the possibility of some correlation between demographic items and results of the study. It was also found that creating the right environment for employees is the first essential step necessary to embrace uncertainty followed by training the employees. Moreover, an improvement in the percentage of responses in dynamic climate was found when only the companies that practice any of the lean construction principles were considered separately from the entire sample. Based on the findings of the research, guidelines for embracing uncertainty in the project and production management phases were developed. The last planner system and OODA loop model when used in tandem was found to be very efficient in embracing uncertainties in the production phase of construction.
