EVALUATING CONTRACT COSTS IN HIGHWAY NEEDS STUDIES

HIGHWAY NEEDS STUDIES USUALLY INCLUDE THREE PHASES: THE NATURE AND QUANTITY OF WORK NEEDED, THE COST OF THE WORK, AND THE PROGRAMMING AND FINANCING OF THE WORK. ALL HIGHWAY DEPARTMENTS HAVE AN ABUNDANCE OF DATA ON CONTRACT UNIT PRICES ON THE SEVERAL HUNDRED CONTRACT ITEMS NOW IN GENERAL USE. BECAUSE HIGHWAY NEEDS STUDIES MUST USE A SMALLER NUMBER OF WORK ITEMS THAN USED IN CONTRACTS, IT IS NECESSARY TO SELECT THE WORK ITEMS AND UNITS TO BE USED AND TO DETERMINE THE PROPER UNIT COSTS FOR THESE ITEMS. USING THE BEST COST DATA AVAILABLE, THE ITEMS AND UNIT PRICES USED IN CONTRACTS MUST BE EXPRESSED IN TERMS OF THOSE ITEMS AND UNIT COSTS TO BE USED IN THE NEEDS ESTIMATE. THE INSTRUCTION MANUAL ISSUED BY THE BUREAU OF PUBLIC ROADS AS A GUIDE SPECIFIES THAT THE FOURTEEN ITEMS BE ESTIMATED SEPARATELY, AND GIVES THE TYPE OF WORK TO BE INCLUDED IN EACH ITEM. BECAUSE THE EVALUATION OF CONSTRUCTION COSTS IN HIGHWAY NEEDS STUDIES INVOLVES THE EVALUATION OF BOTH CONTRACT WORK UNITS AND CONTRACT UNIT PRICES, THE METHODS USED FOR BOTH OF THESE EVALUATIONS IN THE INTERSTATE COST ESTIMATE STUDY ARE OUTLINED. THE ORGANIZATIONAL PROCEDURE IS OUTLINED IN UTILIZING THESE DATA IN PRODUCING A COST ESTIMATE FOR AN INTERSTATE ROUTE SECTION. STRIP MAPS WERE PREPARED FOR EACH INTERSTATE ROUTE USING THE ONE INCH TO ONE MILE COUNTY ROAD MAPS. A REPRESENTATIVE OF THE HIGHWAY DEPARTMENT AND THE BUREAU OF PUBLIC ROADS DECIDED ON THE SUITABILITY OF THE LINE AND GRADES AS PROPOSED, THE TYPICAL SECTION, THE LOCATION AND TYPE OF INTERCHANGES, THE SEPARATIONS, THE ROAD OR STREET TERMINATIONS, AND THE FRONTAGE ROADS. WITH THESE DATA THE CENTRAL OFFICE COMPLETES THE STRIP MAPS WITH APPROPRIATE SYMBOLS. THE FORMS, THE GENERAL DATA TABLES, AND THE STATE MANUAL OF INSTRUCTIONS HAVE BEEN PREPARED. WHEN THE ESTIMATION OF COST ON THE URBAN SECTION BEGINS, SOME VARIATION IN THE PROCEDURE AND SOME SUPPLEMENTING OF THE GENERAL DATA WILL BE NEEDED.
