Economics and procedures for construction of concrete bridges Presented at the 41st annual meeting, January 8-12, 1962

Paper 1: Modern technology has made available new and improved materials, equipment, and techniques that contribute substantially to more economical construction of bridges. Emphasis in this report is placed upon the fields and categories in which advances have been made. A discussion is conducted of the economies that can be achieved by a designer with a complete awareness of shop practices in fabricating plants, form building processes and devices, falsework types available, welding equipment, and new materials. Paper 2: Establishment of structural concrete slabs on three-span continuous structures is usually accomplished by segmental placement. This results is difficulty in obtaining properly constructed, smooth riding surfaces. When composite design and construction was adopted, the segmental practice introduced other undesirable side effects. a request was received to place the structural slab with integral wearing course on the three-span continuous units on the Bruckner Expressway in the Bronx, New York.
