PPVC Considerations and Key Factors

PPVC筹划及关键点

2.1 Early Involvement of Contractors

承包商的早期参与

• Given that each PPVC Fabricator has their own proprietary system for the manufacture of PPVC modules, it is highly encouraged to engage the PPVC Fabricator as well as the Main Contractor early upfront during the design stage to allow their inputs into the design for a better and more effective technical solution.

鉴于每个PPVC制作者有自己的专有系统制造PPVC模块,它是高度鼓励从事PPVC制作者以及主要承包商早期的前期设计阶段期间,允许他们输入到设计一个更好的和更有效的技术解决方案。

• The Design and Build (D&B) and Design Development and Build (DDB) procurement models can be adopted for PPVC projects as they allow greater inputs into the design upfront by the Main Contractor and their PPVC Fabricators. This will vastly increase the buildability and constructability of the PPVC design, leading to greater productivity in construction.

设计和建造(D&B)和设计开发和建造(DDB)采购模型可以被采用在PPVC项目中，因为它们允许主承包商和他们的PPVC制造商在前期对设计进行更多的投入。这将极大地提高PPVC设计的可建造性和可施工性，从而提高施工生产率。

2.2 Types of PPVC Modules

PPVC模块的类型

The choice of material will dictate the size and number of modules in the design as weight is a major consideration for the hoisting of the modules.

材料的选择将决定模块的尺寸和数量，因为重量是提升模块的主要考虑因素。

Other major factors will involve logistics of transportation, site layout and holding area, crane or hoisting position.

其他主要因素包括运输的物流、场地布局和存放区域、起重机或吊装位置。

2.3 Transportation运输

Logistics for modules transportation from factory to site will determine the maximum size and volume of each module design, which in turn affects the number of modules to complete the layout design.

模块从工厂到现场的运输物流决定了每个模块设计的最大尺寸和体积，进而影响到完成布局设计的模块数量。

The size of a single module should be limited to the dimensions allowed to be transported on public road without requiring special measures such as police escort. Height consideration has to be factored in if the route involves passing through overhead bridges.

单个模块的大小应限制在允许在公共道路上运输的尺寸范围内，而不需要采取诸如警察护送等特殊措施。如果路线涉及通过天桥，就必须考虑到高度。

In compliance to LTA‘s traffic regulatory requirements, Police Escort will not be required, when the parameters are controlled.

根据LTA的交通规管要求，当参数受控制时，将不需要警察护送。

Existing road configuration around the site has to be analyzed for the maneuvering and holding of the modules. The deliveries have to be planned and coordinated to avoid congestion outside the site especially for urban built-up areas.

场地周围现有的道路结构必须进行分析，以确定车辆的操纵和控制。运输必须经过规划和协调，以避免现场以外的拥堵，尤其是城市建成区。

2.4 Configuration of PPVC Modules模块组合

The modules are configured according to the design layout. The geometry of the modules can be simplified to design for ease of production.

模块根据设计布局进行配置。模块的几何形状可以简化为易于生产的设计。

The number of modules will vary, depending on the residential unit typology (Studio, 1 to 5 rooms). Total number of modules can typically range from 1 to 8 numbers per unit.

根据住宅单元类型(工作室，1到5个房间)，模块的数量会有所不同。模块的总数通常可以从每个单元1到8个数字。

Demarcation of a typical unit module with reference to plan below is as follows:

参照以下方案划分典型单元模块如下:

• Module A: LRDIN (Living and Dining Room)单元A: LRDIN(客厅与餐厅)

• Module B: B2-IBB (Bedroom 2 with In-built Bathroom)模块B: B2-IBB(2号卧室，自带浴室)

• Module C: MB-IBB (Master Bedroom with In- built Bathroom)C模块:MB-IBB(带内置浴室的主卧)

• Module D: KIT (Kitchen)模块D: KIT(厨房)

Modules can be configured to meet the functional requirements of the building. A typical bedroom of a nursing home can constitute a total of 4 standard modules, to achieve the functional requirements.

可配置模块，满足建筑的功能需求。养老院一间典型的卧室可共构成4个标准模块，实现功能需求。

Demarcation of a typical unit module with reference to plan below is as follows:

参照以下方案划分典型单元模块如下:

• Module A: 1MA

• Module B: 1MB

• Module C: 1MC

• Module D: 1MD

2.5 Type of Hoisting Machinery起重机械类型

Sizing and arrangement of cranes on a site will be dictated by the total lift weight of the module and the reach of the crane.

工地上的起重机的尺寸和布置将由模块的总起重重量和起重机的距离来决定。

Below are some generic information on the type of cranes available.

下面是一些关于起重机类型的通用信息。

Note: Actual crane requirement and capacity shall vary according to the site condition and to be obtained from the crane specialist accordingly.

实际的吊车需求和能力应根据现场情况而有所不同，并由吊车专家提供相应信息。
