This manual is intended as an aid to project engineers and inspectors in inspecting the bridge, culvert, and retaining wall construction. It is not intended that this manual or any provisions thereof, supersede or in any way alter the terms of any contractual obligation. In the event of a conflict between the provisions of this manual and the provisions of the contract, the provisions of the contract shall always control.
In most instances, topics covered are arranged in the same order that they normally occur in actual construction. No attempt has been made to present new or novel methods of construction, but rather to show those that are well established. This should be of particular benefit to those who are inexperienced in this type of construction. Methods presented are by no means the only way to accomplish the work, and it is not intended that the contractor be limited to any specific method(s) mentioned.
