: AI-enabled Smart IoT tagging/sensor system for intelligent, efficient Formwork management (SmartForm)

混凝土芯材越来越多地用于超高层建筑。自2001年纽约世贸中心大楼倒塌以来，很明显，坚固的混凝土核心可以在将生命损失和结构破坏降至最低方面发挥关键作用，而且事实证明，在防火、爆炸和冲击方面，它们优于钢框架核心。高层建筑，如163层的哈利法塔，要求模板高度重复，用于浇筑混凝土结构的一层又一层。然而，这仍然是一个非常劳动密集型的过程，消耗了大量的胶合板，并以副产品和丢弃部件的形式产生浪费。SmartForm项目的目标是开发一种数字技术，以优化模板效率、降低成本和提高生产率。我们应用物联网(IoT)方法引入双向数据流，将现有的BIM数据与持续的传感器输入和现场进度图相结合，提供动态模板管理系统，以减少时间和劳动力需求并优化材料使用，从而减少20%的碳排放和节省40%的混凝土施工时间。由于模板成本高达每平方米58 GB，我们预计使用SmartForm将实现25%的总体节省(劳动力和材料成本节约)，这将为英国建筑业每平方米浇注混凝土节省高达15 GB的成本。

Concrete cores are increasingly used in very tall buildings. Since the 2001 collapse of the World Trade Center Towers in New York, it has become clear that robust concrete cores can play a critical part in minimising loss of life and structural damage and they have been proven to be superior to steel-framed cores in terms of resisting fire, blasts and impacts. Tall buildings, such as the 163-storey Burj Khalifa, require a high degree of repetition in the Formwork used to mould floor-after-floor of a poured concrete structure. However, this is still a very labour-intensive process, consuming large quantities of plywood and generating wastage in the form of offcuts and discarded components. The SmartForm project targets the development of a digital technique to optimise formwork efficiency, reducing cost and increasing productivity. We apply an Internet of Things (IoT) approach to introduce bidirectional data flow, combining pre-existing BIM data with on-going sensor inputs and site progression mapping to provide a dynamic formwork management system to reduce time and labour requirements as well as optimise material use, resulting in 20% fewer carbon emissions and 40% time saving on concrete construction. With Formwork costing as much as £58 per m2, the 25% overall reduction (combined labour and materials cost savings) we expect to achieve with SmartForm would offer the UK construction industry savings of up to £15 for every m2 of poured concrete.
