=Office Engineering Department.=--In the Office Engineering Department are handled the numerous office details in connection with the engineering work of the Department. The more important of these duties are the working up of maps, profiles, specifications and estimates for new projects; the checking of monthly and final estimates for payments on contract work; the filing of engineering records of all kinds; the keeping of cost distribution and the compilation of reports, statistics and other data. During the past year this department, in addition to its other work, prepared and had published a road map of the State of Oregon. This map shows all of the main traveled roads of the State and is believed to be the most authentic as well as the most complete road map of Oregon yet published. A small reproduction of the map is contained in this report. Single copies of a larger size, 13 by 22 inches will be supplied upon application. * * * * * =Bridge Department.=--The Bridge Department prepares designs, plans, specifications and estimates for all bridges and similar structures. The inspection and the supervision of construction of bridges is also in charge of this department. The laws of the State require that bridge designs be prepared for counties by the Highway Department, upon the request of County Courts. Twelve counties have taken advantage of this law during the past two years and have called upon the Department for designs for a total of thirty-four bridges and six culverts, and of these structures twenty-seven bridges and four culverts have been built. A total of ninety-five bridges and fifteen culverts were designed by the Bridge Department, of which fifty-nine bridges and eleven culverts have been constructed. COST KEEPING The keeping of an accurate segregation of expenditures and a detailed distribution of costs for an organization handling the amount of work and the character of work handled by the Highway Department is a matter of the greatest importance. The Highway Department seldom has under way less than eighty or ninety separate and distinct jobs. These jobs are scattered all over the State, and few of them are of sufficient size to warrant the employment of timekeepers on the jobs to keep exact records of expenditures and costs. The records for all of these jobs must be kept in the main office where it is impossible for those keeping the records to be personally familiar with the details of the numerous expenditures made on each of the many jobs.
