ABSTRACT
Construction of modern architectural and engineering works relies on a sophisticated array of project planning, management, and simulation systems to generate multiple, dynamic building scenarios. Construction industry practices such as estimating and scheduling routinely calculate the estimated cost and duration of projects. The standard construction industry estimating process consists of: determining the quantity of material; applying productivity rates to establish the number of person-hours, then multiplying by the pay rates to establish the labor cost. Critical path method scheduling is a network-based modeling system used to evaluate a group of interrelated activities to simulate the time and resource aspects of a project. Productivity is the cost per unit of output measured in terms of person-hours, and is referred to as unit rates. Construction of the adobe shell is by far the most expensive component, with manufacturing, transporting, and installation of adobes representing much of the labor.
