Abstract: Construction of projects such as buildings, bridges, dams, industrial plants, means of transport, or the like with the aid of means and methods for incremental depiction of such buildings, etc. Complex structural features of the construction project are divided into discrete increments and characterized by ordered work activities essential to their construction, then are depicted as in construction drawings to assist in supervision of the project itself. Such characterization and depiction enable urgencies to be emphasized, as by shading structural features due to be started or finished by some given time in the construction schedule differently from those not due until later--or to have been completed earlier. Likewise, during actual construction, deviations from the project schedule can be distinguished readily, as by depicting structural features due (or overdue) in boldest shading and by diminishing the boldness of shading the more time is available within which to complete subsequent features.
