5. GOOD INDUSTRY PRACTICES – INSTALLATION

5.良好的行业惯例-安装

5.1. Adopt Just-In-Time (JIT) concept

5.1. 采用准时制(JIT)概念

Adopting a just-in-time (JIT) concept, where MEP modules are delivered according to the construction sequence, eliminates congestion in the factory and minimises damages to the modules on site. BIM can be used to simulate the actual on-site installation to identify potential problems in the access route.

采用准时制(JIT)概念，MEP模块按照施工顺序交付，消除了工厂的拥堵，并将现场模块的损坏降至最低。BIM可以用来模拟实际的现场安装，识别进入路线中潜在的问题。

Close co-ordination between parties at the project site and factory is critical to ensure a smooth supply of modules to the site and minimise downtime due to missing modules on site.

项目现场和工厂各方之间的密切协调是至关重要的，以确保模块的顺利供应到现场，并尽量减少由于现场缺少模块而造成的停机时间。

5.2. Plan for logistics in advance

5.2. 提前做好物流计划

The method statements and risk assessments for lifting, installing and storing (if applicable) the modules on site require the builder’s inputs on the capacity of cranes, availability of access platforms on each floor for landing of modules, delivery routes of modules to their designated positions, and other logistics constraints.

现场吊装、安装和储存(如适用)模块的方法陈述和风险评估要求建造者提供以下方面的信息:起重机的能力、每层用于模块着陆的存取平台的可用性、模块到指定位置的运送路线以及其他物流限制。

Delivery of large pump skid and modules that may require traffic escorts should be planned in advance.

需要交通护航的大型泵滑块和模块的交付应该提前计划。

5.3. Conduct visual inspections of modules delivered to site

5.3. 对交付到现场的模块进行目视检查

Visual inspections should be conducted by an engineer’s representative to ensure there are no defects to the modules during transportation, prior to moving the modules to their designated location for installation.

在将模块移动到指定位置进行安装之前，应由工程师代表进行目视检查，以确保模块在运输过程中没有缺陷。

5.4. Mark and set out modules’ position

5.4.标记和设定模块的位置

The positions of the supporting rods on the modules, as shown in the BIM drawings, can be marked out on the slab soffit or columns using laser marker equipment. This will ensure faster and proper alignment of supporting rods with module frame eyelets as well as connections between modules.

模块上支撑杆的位置，如BIM图纸所示，可以用激光标记设备在板拱或柱上标出。这将确保模块框架孔和模块之间的连接更快和正确的对齐支撑杆。

5.5. Install and connect modules and to the mains

5.5. 安装并连接模块和电源

The installation of MEP modules should be carried out by workers who are familiar with the connection details of the modules, and have been trained by the MEP prefabricators.

MEP模块的安装应由熟悉模块连接细节并经过MEP预制师培训的工人进行。

5.6. Testing and commissioning

5.6.调试

A testing and commissioning plan should be developed and the Qualified Person (QP) or his representative should be present to witness the testing and commissioning of the MEP system.

制定测试和调试计划，并由合格人员(QP)或其代表出席MEP系统的测试和调试。
