Introduction

前言

Since 2001, BCA had implemented the buildability legislation for all building projects to raise productivity in the built environment sector and reduce its reliance on foreign workers. The mandatory requirements for adoption of buildable designs had also been progressively raised over the years. The legislation has had the effect of changing some of the design practices in the industry, for example, the switch to more flat plate designs, dry walls, precast construction and prefabrication, and adoption of higher repetition of grids, floor-to-floor heights and more repeated component sizes.

自2001年以来，BCA为所有建筑项目实施了可建性立法，以提高建筑环境部门的生产率，减少对外国工人的依赖。多年来，有关采用可建造设计的强制性规定也已逐步提高。这项立法已经改变了行业中的一些设计实践，例如，转向更多的平板设计、干墙、预制施工和预制，以及采用更高的网格重复、地板到地板的高度和更多重复的组件尺寸。

In 2011, BCA introduced the constructability requirements for builders to adopt more labourefficient technologies and methods to improve productivity during construction. This helps to ensure that productivity concepts initiated during the upstream design phase by architects and engineers would be implemented with labour-saving construction processes by builders during the downstream construction phase.

2011年，BCA引入了可施工性要求，要求建筑商在施工过程中采用更高效的技术和方法来提高生产率。这有助于确保建筑师和工程师在上游设计阶段提出的生产力概念能够在下游建造阶段通过建筑商节省人力的建造过程得以实施。

To accelerate the built environment sector’s productivity improvement, especially in view of the more aggressive reductions in foreign worker supply, BCA raised the minimum standards for Buildable Design Score and Constructability Score further in 2013. At the same time, the buildable design requirements were tightened to propel the industry towards adopting a greater degree of standardisation in building components and design parameters.

为了加快建筑环境部门生产率的提高，特别是考虑到外国工人供应的大幅减少，BCA在2013年进一步提高了可建造设计分数和可建造性分数的最低标准。与此同时，当局亦收紧了可建造性设计的规定，以推动业界在建筑组件和设计参数方面采取更大程度的标准化。

Going forward, there is a need to lift productivity onto a higher plane by getting the industry to design and construct more buildable buildings and to exploit more labour-efficient technologies and productive methods of construction. Thus, in 2014 and 2015, besides further raising the minimum scores, BCA has mandated the adoption of key productivity components including industry-wide standard dimensions and building components for specific types of development. In addition, specific productive technologies have also been stipulated as land sales conditions for developments sold under the Government Land Sales (GLS) Programme.

展望未来，有必要通过让工业设计和建造更多可建造的建筑物，开发更省力的建筑技术和生产方法，将生产率提高到更高的水平。因此，在2014年和2015年，除了进一步提高最低分数之外，BCA还要求采用关键的生产力组件，包括行业范围的标准维度和为特定类型的开发构建组件。此外，还规定了具体的生产技术，作为在政府土地出售方案下出售的发展项目的土地出售条件。

This helps to pave the way for the industry to adopt the Design for Manufacturing and Assembly (DfMA) approach, by moving as much construction work off-site to a controlled manufacturing environment as possible and minimising work on site.

这有助于为工业界采用“为制造和装配而设计”(DfMA)方法铺平道路，将尽可能多的施工工作转移到一个受控的制造环境中，并将现场工作最小化。

While the industry has made good progress over the years, there is a need to build on the momentum and continue to strive for higher productivity improvement. As part of the larger drive towards wider adoption of prefabrication technologies along the DfMA continuum, the buildability legislative framework has been enhanced further to raise construction productivity.

虽然业界多年来已取得良好的进展，但仍有需要在这一势头的基础上，继续致力提高生产力。为了在DfMA范围内更广泛地采用预制技术，我们进一步加强了可建造性立法框架，以提高施工效率。

This Code sets out the requirements of minimum Buildable Design Score, minimum Constructability Score and their submission procedures. It also sets out the method of determining the Buildable Design Score and the Constructability Score, as well as the requirements for the specific productive technologies stipulated for GLS sites which need to be fulfilled. Some amendments and revisions may be expected from time to time.

本规范规定了最低可建造性设计评分要求，最低可建造性评分要求和提交程序。阐述了可建造性设计分和可建造性分的确定方法，以及对GLS场地规定的需要满足的具体生产技术的要求。可能会不时地进行一些修订和修订。
