FOREWORDAbout two years ago, after several talks at theMaster Builders’ Association on “Quantity Surveys,”it was deemed advisable, whatever builders gener ally might think of this method of estimating, toformulate some “Standard Units” and “Methods forMeasuring” building quantities.Messrs. Isaac F. Woodbury,'Charles Logue andArthur W. Joslinwere appointed a Committee in the matter, and thefollowing system of units and rules for measure ments are the result of their work.These rules have been submitted to and approvedby a Joint Committee of Architects and Builders.If estimators will consistently follow them it willbe a long step forward in the direction of uniform ity in a matter that has been handled in about asmany ways as there are estimators.The Building Trades Employers’ Association ofBoston feels that it is for the benefit of the buildingindustry to disseminate this information in the hopethat surveyors of building materials from architects’and engineers’ plans will make use of the system ofunits and rules for measuring herein set forth.It was therefore voted by the Building TradesEmployers’ Association of Boston, at its regularquarterly meeting held October 3, 1917, to print thiscompilation of rules and distribute copies to its mem bers and others interested in improving conditions inthe building business.,March, 1918.
