A study of the effectiveness of the Clear Flow Matrix in building construction projects

Cost overruns, schedule delays, and contractual claims are commonplace in construction projects. These issues often are the result of poor planning by the construction management team, or the improper alignment of field production management and control with the project schedule. To ensure that the schedule is properly executed in the construction process, the production management and control system must be manageable, intuitive and visually evident for all levels of management and trade supervisors. This need is especially critical for building construction, where client requirements often result in changing project demands, particularly for interior equipment and finishes. The various finish trades for a large building with many segments or floors may produce a large number of trade-location activities for the construction team to manage during construction. Thus, a good production plan is required to implement the schedule. Lott Brothers Construction Company has created a novel production management and control technique entitled, the Clear Flow Matrix (CFMx). The technique consists of a matrix integration of the trade activities and locations wherein time and workflow rhythm are represented through the progress of a unique Balanced Workfront, which balances client completion demand and trade contractor operations efficiency as trade work progresses through the building areas. The visual nature of CFMx and the Balanced Workfront provides the project participants with a production framework for managing production and documentation of trade-exchanges so critical for quality completion of the work in accordance with the contract schedule. The thesis discusses the theoretical underpinning of the CFMx and how the embedded concepts are used to produce this visual matrix framework for production management and control to deliver the project in full alignment with the master schedule. The thesis provides several example applications of the Clear Flow Matrix to various types of building construction projects. Data collected from the applications through jobsite observations of the work (Work Sampling Analysis) and questionnaire interviews of trade contractor foremen and project managers provide insights into the effectiveness of the Clear Flow Matrix in comparison with other production management techniques currently used in the construction industry.
