Multiplan Models for Construction

As computer hardware becomes smaller and increasingly less expensive, more contractors can now use computers to do a number of construction computations which were formally done on hand calculators. The advent of user-oriented software packages has had a significant impact on the traditional data processing procedures of the construction industry. Among the software packages that are available for a large number of computer systems are electronic spreadsheets. Electronic spreadsheets packages, such as Multiplan, are widely used where the display of information can best be depicted in an array of rows and columns. It is frequently useful in situations in which the user wants to change various elements of information or try out various assumptions in a “what if” analysis. This paper discusses, among other things, models for two very important aspects of construction: those of cost estimating and scheduling. The paper further discusses the capabilities of spreadsheets in general as they relate to specific application to the construction industry. A graphical model of a CPM precedence diagram to be used in construction scheduling is presented along with a table for estimating the cost of a building based on the structural components of which it is made. There is also discussion of other software packages with similar capabilities to Multiplan
