1. In a totally integrated construction estimating, analysis, and reporting computer system having procedures which automatically determine, based on input parameters, individual algorithms and knowledge-based factors representative of various functional, physical, and geographic requirements of a facility, including a breakdown of materials at a facility system level which includes functional areas of primary and supporting facilities, and decreasing levels of a hierarchy down to an elemental level which includes material, labor, and equipment;

  • wherein said system comprises;

    manual-entry means for entering initial input parameters which include parameters indicative of the type, size and location of the facility;

    knowledge base file means comprising data on functional, physical, and geographical construction requirements of the facility, and a plurality of algorithms representative of knowledge construction principles and human judgments applicable to the facility at said facility systems level, and other levels on down to the elemental level;

    means for generating a model of the facility at said facility systems level and other levels on down to the elemental level including;

    inference and control means using said knowledge base file means and said initial input parameters for determining a set of system parameters and default values thereof relating to the facility at a system level, with typical values being defined, means for modifying the system parameters by manual entries;

    inference and control means using said knowledge base file means for determining subsystem parameters for a plurality of subsystems within the facility, as a function of said initial input parameters and said system parameters, means for modifying the subsystem parameters by manual entries;

    inference and control means using said knowledge base file means for determining assembly category parameters for a plurality of assembly categories within the facility, as a function of said initial input parameters and said system and subsystem parameters, means for modifying the assembly category parameters by manual entries;

    inference and control means using said knowledge base file means for determining assembly parameters for a plurality of assemblies within the facility, as a function of said initial input parameters and said system, subsystem and assembly category parameters, means for modifying the assembly parameters by manual entries;

    inference and control means using said knowledge base file means for determining parameters for a plurality of line item elements within the facility, as a function of said initial input parameters and said system, subsystem, assembly category and assembly parameters, to determine material, equipment and labor inclusive in individual line items, means for modifying the parameters for the line items elements by manual entries.
