The enclosed project is presented by a construction sector startup company (Net Zero Projects - "NZP") that has a vision for more sustainable structural engineered products e.g. concrete beams, slabs and frames.At present the construction sector produces concrete beams based on methods that are biassed toward simplified manufacturing processes. In effect, rectangular form work (elongated boxes) are produced in the required size and then concrete is poured into the form to set solid. However, this is very wasteful, a good proportion of the volume of the concrete beam provides limited strength to the beam so a large proportion of the carbon footprint, associated with concrete and production process, is emitted wastefully.NZP has a radical solution for an "optimised" concrete beam that combines 3D concrete printing, intelligent structural design and steel cables to drastically reduce the amount of concrete, reinforcing steel and embedded carbon needed to produce a concrete beam. To date, NZP has developed and produced a 3D printed concrete beam that provides 70% reduction in embodied carbon and up to 50% reduction in material costs, compared to similar traditional concrete beams.NZP has had commercial interest from construction sector clients. However, at present NZP can only produce a beam suitable for being supported at both ends. To be commercially viable, the company needs to produce cantilever beams (i.e. beams only supported on one side). This is possible but only with the development of some specialist automated design software and experimental testing of cantilever beam designs.The enclosed Fast Start Innovation application will enable NZP to resolve these challenges and exploit commercial demand for lower carbon structural engineered products. This project is fully aligned with the "Achieving net zero and reducing environmental impact" competition priority.

所附项目由一家建筑行业初创公司（净零项目 - “NZP”）提出，该公司致力于开发更可持续的结构工程产品，例如混凝土梁、板和框架。目前，建筑行业生产混凝土梁的方法偏向于简化制造工艺。实际上，矩形模板（细长的盒子）按所需尺寸生产，然后将混凝土浇注到模板中以凝固。然而，这是非常浪费的，混凝土梁体积的很大一部分为梁提供了有限的强度，因此与混凝土和生产过程相关的大部分碳足迹被浪费了。NZP 有一个根本性的解决方案“优化”混凝土梁，结合了 3D 混凝土打印、智能结构设计和钢缆，大大减少了生产混凝土梁所需的混凝土、钢筋和嵌入碳的用量。迄今为止，NZP 已开发并生产了一种 3D 打印混凝土梁，与类似的传统混凝土梁相比，其碳含量减少了 70%，材料成本降低了 50%。NZP 已引起建筑行业客户的商业兴趣。然而，目前NZP只能生产适合两端支撑的梁。为了实现商业可行性，该公司需要生产悬臂梁（即仅在一侧支撑的梁）。这是可能的，但只有通过开发一些专业的自动化设计软件和悬臂梁设计的实验测试。随附的快速启动创新应用程序将使 NZP 能够解决这些挑战并开发对低碳结构工程产品的商业需求。该项目完全符合“实现净零排放，减少环境影响”的竞争重点。
