I am planning a medium-sized office—three to five storeys—that must stay standing and operational even when the surrounding area floods. Steel will be the primary structural material, so the design needs to leverage its strength and flexibility while protecting against corrosion and water intrusion. Here’s what I need from you: • Conceptual and structural drawings that show how the steel frame, foundations, and connections will handle sustained flood forces and hydrostatic pressure • A drainage and waterproofing strategy (e.g., elevated slab, sump pumps, water-tight detailing) that keeps critical spaces dry • Material and component specifications, including any coatings or composite members that improve durability in wet conditions • Basic calculations or simulation outputs proving the design meets local building codes for flood zones and medium-rise offices If you can also suggest cost-effective construction sequencing or phased implementation to minimise downtime during a flood event, that would be a bonus. I’m looking for clear, professional documentation that a local contractor and engineer can take straight to permitting and construction.
