importance of an item in the project should be one of the primary factors in determining if a submittal for the item should be required A G following a submittal item indicates that the submittal requires Government approval Some submittals are already marked with a G Only delete an existing G if the submittal item is not complex and can be reviewed through the Contractor s Quality Control system Only add a G if the submittal is sufficiently important or complex in context of the project For submittals requiring Government approval on Army projects a code of up to three characters within the submittal tags may be used following the G designation to indicate the approving authority Codes for Army projects using the Resident Management System RMS are AE for Architect Engineer DO for District Office Engineering Division or other organization in the District Office AO for Area Office RO for Resident Office and PO for Project Office Codes following the G typically are not used for Navy projects Submittal items not designated with a G are SECTION 03330 Page 3 美国混凝土学会 美国混凝土学会 ACI 211 1规范 美国混凝土学会 ACI 211 2规范 普通混凝土 重混凝土和大体积混凝土选择比例的标准规程 1991 2000修订 美国混凝土学会 ACI 301规范

可以删除已经存在的G的标识 只有 在提交的文件是非常重要或者项目 文本非常复杂时 才能增加G标识 对于提交给政府审批的关于陆军项目 的文件 在提交符号达到3个特征时 可能会采用以下G标识来标示批准的 官方部门 对于陆军工程的居住管理 系统 RMS 的代码是 AE代码是指 建筑工程师 DO是行政区办公室 工程部或其他在行政区的组织 AO指地区办事处 RO指常驻办事机 构 PO指项目办公区 海军项目不 使用典型的G代码 不使用G标识的提交款项将被认为是陆军 项目中的仅从参考的涵义以及在海军项目中 是被承包商质量控制批准的 considered as being for information only for Army projects and for Contractor Quality Control approval for Navy projects SD 04 The materials used in architectural concrete vary from one project to another For most projects samples for all materials are not required A list of suggested samples is given below Form Ties Form Liners Cement Colors Coarse Aggregates Reinforcing Chairs Sample panels should not be required for small projects Government approval is required for submittals with a G designation submittals not having a G
