SOMORPHISM OF STANDARD TO DESIGN ADJUSTED, RESOURCES UTILIZATION EFFICIENCY AS A NEXUS FOR BUILDABILITY EVALUATION

In spite ofthe importance of the concept of design buildability, it has found little application in construction management because the concept is yet to be validly measured. It is for this purpose that this study aims at developing an evaluation technique that is mathematically valid, to generate a metric for measuring buildability which does not only preserve transitive order but that also measures distance. Buildability was modeled into the Resources Utilization Efficiency (RUE) equation as a disturbance (????????) for each construction activity, using mathematical theory of lattice algebra. The disturbance was isolated, through analytical estimating and mapped to standard RUE lattice as an isomorphic image. The isomorphism was therefore evaluated and used as the nexus for buildability evaluation. The study found that buildability is defined by the isomorphism of the design adjusted RUE lattice mapped to standard RUE lattice. Buildability metric would find application in Construction Management as a parameter in Management Information System (MIS) for evidence-based decision making in areas of tender adjudication, estimating, construction programming, project planning and design comparison. Stems from the development of an interval scale for measuring buildability concept that generates a metric that preserves order and measure distance from an assumed origin of the standard RUE.
