The Aberthaw Index of Building Construction. This
index of building construction is summarized in the United
States Department of Commerce, Office of Business Economics,
Business Statistics, 1957> Biennial Edition, as follows:
Compiled by the Aberthaw Company, Construction Managers, Boston, Massachusetts. Beginning 191+6, the index measures changes in costs of 36 major items entering into the construction in the New England area of five types of industrial buildings--three four-story types (wood frame, brick walls; steel frame, wood floors; reinforced concrete flat slab) and two one-story types (steel frame, monitor roof; reinforced concrete, monitor roof). New England prices of material Items and labor rates are weighted on the basis of estimated quantities of materials and amounts of labor required for the types of buildings included. Labor rates are current New England union rates for all trades. The Index includes all building-construc- tion expense, with the exception of home-office expense and architects’ or engineers’ fees.
The index prior to 191+6, to which the current series is linked, is based on changes in the cost of constructing
an eight-story reinforced concrete industrial . structure originally built by the company in Connecticut in 1911+, in which cement, steel, sand, gravel, lumber, and glass constituted the major items. The index is confined to labor, materials and other construction costs actually required for construction of the building,
and excludes data for home-office overhead and profit on the job, as in the current series. . . .
