埃克塞特有悠久的洪水历史，返回到13世纪。目前的洪水防御是在20世纪60年代和70年代建造了70年代，影响了超过1,000个房产。虽然目前的防御在过去的40年里有效工作，但环境署的研究表明，在更极端的洪水局势中，目前的防御将无法保护城市的脆弱部分。新的3200万英镑计划旨在将洪水风险降低到埃克塞特核心的3,000多个房屋和企业。在埃克塞特市中心下游，主要作品包括泛洪通道和堰，旨在提高高河流动期间的能力。在市中心本身和专门沿着历史码头旁边，新的洪水防御包括永久固定的钢柱，在洪水风险高时将安装可拆卸障碍。该方案的规划条件需要这些工业风格的帖子，以传统的系柱式的“袖子”覆盖，以便与码头所在的河滨保护区的内置环境保持一致。
Main contractor BAM Nuttall approached Furnitubes’ designers to discuss the feasibility of various material options, with the challenges being not only the aesthetic appearance of the sleeves but also the practical lifting operation given its height and weight, and a locking mechanism to prevent the sleeves being removed by the public, whilst still being easy to remove by Environment Agency staff when the flood defence barriers need to be installed. With the flood defence posts standing at 1.35m high, it was immediately apparent that the sleeve solution would need to be lightweight to be comfortably lifted off the post, leading to the decision to pursue a design in plastic. As a moulded material plastic also lends itself to creating the kind of ornate detailing typical on cast iron bollards that the sleeves were required to mimic. The design of the sleeve was highly complex, with the assembly comprising two purpose-made rotational mouldings (for which new tooling was made), connecting stainless steelwork and also a discreet locking mechanism, and with several special variations to deal with variable ground level conditions along the quayside. The Quay remains open to local traffic so a tough plastic is an ideal material in the event of a low speed vehicular impact – sufficiently robust not to deform from light impact but not so hard to cause serious damage to a vehicle. Plastic also has the benefit (over steelwork) of offering greater corrosion resistance in this potentially aggressive marine environment.
