Abstract: In 2008, AACE International members interested in advancing the state of estimating in building information modeling (BIM) began collaborating with members from the American Society of Professional Estimators (ASPE), and members from the Royal Institute of Chartered Surveyors (RICS), to define the information exchange requirements for cost estimating in BIM. The information exchange requirements are the basis for an information delivery manual (IDM) required from the designer to the estimator. This is a unique and important effort for estimators to take an active role in developing a future national standard. Without defined requirements for information exchange, estimators run the risk of receiving a BIM that is populated with inaccurate or incomplete project information. The ultimate goal of the collaborative effort, reported in this paper, is to produce a ballot item for submission to the National BIM Standard (NBIMS). This paper reports on the process development to date and the future plan for the collaborative effort.
