Classes Of Photographs. Many engineers and contractors require two classes of photographs to be taken on all pieces of work: Construction photographs, which are kept for record of the method and progress of the work; and what may be termed "publicity photographs," kept for showing the class of work the firm is engaged in, thus influencing prospective clients, and for advertising purposes.
Superintendents Of Construction Can Make The Photographs. Among firms following this method are Dodge & Day, of Philadelphia. Each of their superintendents of construction is provided with a film-camera taking a photograph 4 x 5 inches. At regular intervals photographs of the work in progress are made, a placard giving name of client and date having been placed on the work. The film is returned to the home office, and two prints of each negative are made by the firm's photographic department. The films are kept on record in that department. Consecutive numbers are given to each plate, regardless of what job it comes from; each job is given a letter, which is prefixed to the number. One print is kept at the home office, and one print is sent to the superintendent on the work. The print in the office is properly filed under the letter and date, in a cover provided for that purpose.
Photographs Aid In Publicity And In Securing Business. The publicity photographs are made 8 x 10 inches in size, by the firm's regular photographer, at such intervals during the course of work as will insure interesting pictures. These plates are given consecutive numbers and a blue-print of each plate is kept on permanent file in the home office.
Photographs As Evidence. While the primary purpose of these photographs is to secure a record of progress and to supply material for publicity, they are valuable evidence in case of disputes; and, moreover, they often act as a sort of police power in the prevention of litigation. The knowledge on the part of a sub-contractor that the general contractor has dated photographs of the work on which he has been employed, will tend to discourage the presenting of unjust claims. Cases of dispute which have come up, and which otherwise would have gone to court, have been satisfactorily settled when the photographic records were referred to.
359. If a company employs its own photographer, there is an advantage in having a man who has some knowledge of engineering. In fact, some concerns consider an insight into engineering problems of more value than an expert knowledge of photography. For securing its photographic records the George W. Jackson Company, of Chicago, has in its employ a man of some technical training who is an amateur photographer. He is engaged continually in
