Revision Notes
This standard is revised by Beijing Equipment Installation Engineering Company on the basis of the "Elevator Installation" chapter in the "Standards for Quality Inspection and Assessment of Building Installation Projects - General Machinery and Equipment Installation Projects" TJ305-75, based on the former National Construction Committee (79) Jianfa Shizi No. 168 and the former Ministry of Urban and Rural Construction and Environmental Protection (85) Chengke Zi No. 293. After the revision, it is named "Elevator Installation Project Quality Inspection and Assessment Standards", with a total of two chapters, six sections and 45 articles.
In order to meet the needs of the rapid development of elevator installation in my country, this revision has made major supplements and modifications, adding 35 new articles, highlighting the requirements of "safe operation", "functional use" and "appearance quality". At the same time, according to the provisions of the "Uniform Standard for Inspection and Assessment of Construction Installation Engineering Quality", this standard divides the sub-projects into "guaranteed projects", "basic projects" and "allowable deviation projects". The quantity requirements for each project are put forward as much as possible. At the same time, two quality grade standards of "qualified" and "excellent" are stipulated in the "basic projects".
During the revision process, extensive investigations and studies were conducted, and opinions from all aspects of the installation industry and the elevator industry were integrated. After writing the "first draft", "draft for soliciting opinions" and "draft for review", relevant experts were invited to study and modify the technical provisions, and a trial was organized. It was reviewed and approved at the national review meeting held in Guiyang in March 1987. During the implementation process, please send your opinions and relevant materials to Beijing Equipment Installation Engineering Company for reference in future revisions.
