  1. Connection Details for Prefabricated Bridge Elements and Systems Michael P. Culmo, P.E. Vice President of Transportation and Structures CME Associates, Inc., East Hartford, CT

  2. The primary concerns that owner agencies have with respect to adopting accelerated construction techniques are: Need for Quality Details Durability Design Methodologies and Training Construction Methodologies Roadblocks to Accelerated Construction

  3. FHWA has initiated a project to develop this manual This publication is intended to provide information that will go a long way to answering all four of the previous concerns. Focus on details that have been used in the past. “Connections Details for Prefabricated Bridge Elements and Systems”

  4. Gather details of Connections that have been used on accelerated bridge construction projects Investigate transfer of technology from other markets into the bridge market Parking Garages Stadiums Buildings Connection Details for Prefabricated Bridge Elements and Systems Project Goals

  5. All details needs to pass a critical test before being published in the document: Does the connection result in a rapid construction process? Does the connection transmit the forces between elements effectively? Is the connection durable? Has it performed well under traffic and in an exposed environment? Is it cost effective and easy to construct? If a process or connection is proprietary, can it be incorporated into numerous projects without producing contracting issues?
