Creation of a Hybrid Insulated Structural System to Enable Delivery of a Disruptive High Volume House Building Model – Hyb-ISS

传统的现场施工方法是英国房屋建筑行业生产率低的主要负面因素，该行业越来越难以吸引所需的技能。在全面实施数字技术的支持下，房屋建筑行业的非现场施工有望大幅提高生产率，性能和一贯的高标准。然而，目前只有不到10%的施工是在场外进行的。不断增长的需求，加上不太理想的施工质量和不断减少的技能基础，已经造成了一个困境，如果不对施工的生产力和质量进行“逐步改变”，这个困境就无法解决。异地施工的好处包括一致性、质量保证（包括Hackitt评论建议的从规格到安装的“黄金线”可追溯性）、更快的施工时间、减少浪费、最大限度地减少缺陷和更低的危险工作条件。在2017年的白色文件中，政府概述了一系列举措，并为行业制定了至少建造250个，Fusion Building Systems（Salvesen Insulated Frames Limited的商品名），Aggregate Industries（LafargeHolcim集团的一部分）和Crest Nicholson将在Hyb-ISS项目中合作开发材料和工厂化工艺，用于生产房屋墙壁，屋顶和地板的成品，不燃，预绝缘结构板。一系列产品将完全符合建筑信息管理（BIM）协议下的最新数字技术。这是第一次在减轻重量的面板中，非现场制造，零可燃性以及改进和完全可追溯的构建质量的优势将提供给行业。与现场施工相比，建造成本降低10% - 15%，建造时间缩短约30%，以支持政府到2039年每年建造250，000所房屋的目标。该项目将提供原型材料和工艺，以及用于初步防火，隔热，声学和结构测试和评估（最初在外墙和隔离墙应用）在现场试验与主要的房屋建筑商，佳洁士。

Traditional site-based construction methods are a major negative contributory factor to the UK's housebuilding industry's famously low productivity and the sector is increasingly struggling to attract the skills it needs.Offsite construction in the housebuilding industry promises hugely improved productivity, performance and consistently high standards, supported by full implementation of digital technology. Yet, less than 10% of construction currently occurs offsite.Growing demand, coupled with less-than-optimal build quality and a reducing skills base, has created a dilemma that will not be resolved without a 'step change' in productivity and quality of build. Offsite construction benefits include consistency, quality assurance (including a 'Golden Thread' of traceability from specification to installation, as recommended by the Hackitt Review), faster construction times, reduced waste, minimised defects and less hazardous working conditions.In its 2017 White Paper, the Government outlined a range of initiatives, and a target for the industry to build at least 250,0000 new affordable houses year on year to 2039.Fusion Building Systems (trading name of Salvesen Insulated Frames Limited), Aggregate Industries (part of the LafargeHolcim group) and Crest Nicholson will collaborate in the Hyb-ISS project to develop materials, and a factory-based process, for production of finished, non-combustible, pre-insulated structural panels for house walls, roofs and floors. A range of products will be fully compliant with the latest digital technologies under Building Information Management (BIM) protocols. For the first time in a reduced-weight panel, advantages of offsite manufacture, zero combustibility and improved and fully traceable build quality will be available to the industry. A 10% -- 15% build cost reduction, and build lead-times shortened by ~30% compared to onsite construction will be targeted in support of the government's goal to build 250,000 houses year on year to 2039.The project will provide prototype materials and process, and prototype pre-insulated panels for preliminary fire, thermal, acoustic and structural testing and evaluation (initially in exterior and separating wall applications) in field trials with major housebuilder, Crest.
