　 1.0编制目的及适用范围： Purpose for Preparation and Scope of Application

　1.1

　本规定适用于上海SECCO 90x104t/a乙烯项目（以下简称SECCO项目）的现场施工质量管理工作。 These stipulations are applicable to the site construction quality management of Shanghai SECCO 90x104t/a Ethene Project (hereinafter referred to as SECCO project).

　1.2 本规定是为了明确SECCO项目的现场施工质量管理工作的职责、工作内容、工作流程、方法以及设计、采购、施工的协调，推行现代化、科学化、规范化的项目管理模式而编制的。

　These stipulations are prepared for the purpose of defining the responsibilities, working contents, operating process and procedures for the site construction quality management of the SECCO project and for coordination among the design, procurement and construction, so as to pursue the modernized, scientific and standardized mode for project management.

　2.0 编制原则 Principles for Preparation

　2.1

　本细则在项目质量管理目标合理分解、项目质量管理组织已经确立的前提下，以项目的规律效应性和操作实用性为原则编制的。 These rules are prepared on the principle of the law effectiveness and operating practicability of the project, under the precondition that the objectives of the project quality management have been reasonably decomposed and the organization of project quality management has been established.

　2.2 本细则注意到质量检验评定中工程划分与WBS分解结构在施工管理中的内在联系，我们强调将两者的划分尽量统一。

　These rules have given full attention to the inherent links between the project component division in the quality inspection and evaluation and WBS decomposed structure in the construction management. We emphasize that the two divisions should be unified as far as possible.

　2.3

　为加强主动控制的力度，本细则建议建立专业施工管理台帐，将施工质量控制纳入现场施工管理体系，专业工程师应参加重要的材料和设备的招标订货会议，了解产品质量、合同技术要求、厂家售后服务及到货情况。以便在施工管理台帐中列出每月到货清单，使材料报检及工程报检工作系统化。 In order to strengthen the power of active control, it is recommended by these rules that a specialized construction management record book is established to integrate the construction quality control into site construction management system. It is also suggested that specialist engineers should participate in the bidding and ordering meetings for important materials and equipment to get acquainted with the product quality, the technical requirements of the contract, after-sale service provided by manufacturer and the delivery status. And then it is possible to put the monthly goods-arrival list in the construction management record book and to realize the systematization of material acceptance and engineering inspection procedures.
