Abstract

The fundamental object of a bridge or culvert survey is to secure information from which to determine the type and size of structure to use. The information secured must be complete enough to em1hle the designer who is unfamiliar with the bridge site to formulate a decision as to the type and details, The structure best suited to meet the conditions and to check recommendations. The refinements of the survey depend largely upon the local conditions encountered and the type of the proposed structure. The engineer securing the notes must be relied t1pon, to obtain complete data even though such information is not specifically mentioned in the outline following. It is necessary that every survey be accompanied by a definite recommendation and vice versa. Standard forms for sending in the information for design will be supplied by the Commission.
