This report describes a system of cost indices for updating early government estimates of the costs of heavy construction in civil works projects. The system provides national indices specific to 19 major construction types features. The feature indices are computed from three levels of subindices which provide increasing detail. The first level below the feature consists of indices for five primary categories of work-earthwork E, concrete C, steel S, mechanical M, and electrical L-and a secondary category, buildings B. The third level breaks each category into labor L, plant P, and material M resource classes. The lowest level provides indices for the actual resource types used in the construction for each resource class. The user can either use the feature index as provided or modify it by changing the weighting of one or more of the items in the three lower levels. The indices can also be regionalized by substituting region-specific resource type indices at the lowest level.
