21 APPENDIX A Survey Questionnaire NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM PROJECT 20-5, SYNTHESIS TOPIC 33-10 STEEL BRIDGE ERECTION PRACTICES OWNER QUESTIONNAIRE There are many varied steel bridge erection practices, used on increasingly complex structural systems, which have a signifi- cant effect on the final profile, location, and position of the erected members. The primary concern is how do these different erection practices, as prescribed by owners and/or developed and implemented by erectors, affect the final position and func- tion of the erected members. This questionnaire is only for steel I-girder and box-girder bridges, with particular empha- sis on curved, skewed, and staged or widened structures. Your help in developing a synthesis report of the issues, problems, and results of these erection practices is requested through the completion of this questionnaire. The information you provide will be used to develop a report that will provide an up-to- date compilation of current issues, problems, and practices. Please return your completed questionnaire via e-mail, before August 9, 2002, to frbeckmann@att.net. Please send the requested specifications and other documentation before August 9, 2002, to: Fred Beckmann Consultant 167 Hawthorne Lane Chicago Heights, IL 60411 If you have any questions, please contact Mr. Beckmann by telephone at 708-754-1677 or by e-mail at frbeckmann@att.net.
