| Published By | Publication Date | Number of Pages |
| ACI | 2005 | 18 |
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.
