    <abstract>A study on 831 daily work orders collected from five construction sites showed that a foreman can generate a bill of materials (BOM) quickly for daily work orders consisting of engineered-to-order (ETO) materials but that for daily work orders consisting of made-to-stock (MTS) materials, the process can be time consuming (e.g., 12-68 minutes per daily BOM). To help a foreman expedite the speed of generating a daily BOM consisting of MTS materials, this research develops a concept referred to as a smallest workface boundary (SWFB) - a boundary that encapsulates a set of level of development (LOD) 400 elements in the smallest workable unit for a certain trade with the objective of assisting a foreman in quickly generating a daily BOM. Through iterative field studies at a lab and nine construction sites, the concept of SWFB was developed, tested with foremen, and incrementally improved to speed up the process of generating a daily BOM for a foreman. With the latest version of the prototype, foremen were able to generate a daily BOM in 59 seconds on average.</abstract>
