This guide presents information and design criteria for shoring\/reshoring operations during the construction of reinforced and post-tensioned multi-story buildings. It provides methods for developing safe construction schedules and provides design examples. It is written for the use of form-work engineer\/contractors and engineer\/architects. Keywords: construction loads; falsework; form removal, formwork; post-tensioning; reshoring; shoring.<\/p>\n
