安装

7.1 Access and Egress

出入口

• An access has to be provided for workers to move in and out during an installation. Any open area will have to be covered with safety barricade to prevent any worker from falling from height. A clearly demarcated egress has to be provided as well to allow workers to exit the work area in the case of an emergency.

在安装过程中，必须为工人提供进出通道。任何开放区域都必须覆盖安全路障，以防止任何工人从高处坠落。在紧急情况下，还必须提供明确划分的出口，以便工人能够离开工作区域。

7.2 Vertical and Horizontal Alignments

垂直和水平排列

• Special attention has to be given to the alignments during installation. The method statement for installation should indicate clearly how proper alignments can be achieved to prevent any abortive works.

在安装过程中要特别注意排列。安装的方法声明应该清楚地说明如何实现正确的对齐，以防止任何失败的工作。

• Improper vertical and horizontal alignments cause external gaps which require additional touch-up work such as hacking and plastering. Windows and/or any external fixtures will look slanted as well.

不正确的垂直和水平排列会造成外部缝隙，需要进行额外的修补工作，如挖孔和抹灰。窗户和/或任何外部固定装置看起来也会倾斜。

• MEP services including lightning protection system, sanitary and rain water discharge system etc. require proper vertical continuity connection. Installation of P-trap, S-trap if required, shall not impact finishes done up in a factory. If vertical concealed shaft is provided, space for installation works shall be allocated to facilitate vertical connection works.

MEP服务，包括防雷系统、卫生和雨水排放系统等，需要适当的垂直连续性连接。安装p型疏水阀和s型疏水阀(如有需要)不应影响工厂的成品。如设有垂直隐蔽竖井，则须预留空间进行安装工程，以方便进行垂直连接工程。

• For MEP services that require installation works horizontally crossing modules, (including wiring, pressurized pipeworks, gradient pipeworks), the method of connection, if required, shall not compromise the level of continuity. All point of connections shall be properly secured by proper support. Method of connections shall not compromise the gradient required for gradient-pipeworks. Proper protection to finishes to be provided if hot work is required for connections. Installation works shall be done via the space allocated for installation works.

对于需要水平跨越模块安装的MEP服务，(包括布线、加压管道、梯度管道)，如果需要，连接方式不得影响连续性水平。所有连接点都要用适当的支撑物妥善固定。连接方法不应影响梯度管道工程所需的梯度。如果连接需要进行热工，则应提供对表面的适当保护。安装工程应按所分配的空间进行。

7.3 Sequencing of the Modules Installation

模块安装的顺序
