Abstract:The sorting and archiving of documents during the implementation of water projects is of great significance for ensuring the construction quality of the project and for the later maintenance and management after the project is delivered. Combined with the implementation of the main part of the Shuanghou Reservoir Project on the Meng River in Linyi Municipality, this paper discusses aspects such as the existing problems in documentation management during the construction process of water projects, the sorting and archiving of the construction documents of Shuanghou Reservoir, and information-based documentation management, with expectation for providing a reference for the documentation management during the construction period of water projects.
