Certification Letter for Steel Shed Flood Resistance

I need a licensed structural engineer to issue a formal, signed letter certifying that our steel shed will withstand a 1 in 100-year flood event without any significant damage. The letter will be submitted to the local council as part of compliance requirements before installation begins. You will have access to the shed plans and any additional details needed to complete the certification. Please outline your qualifications and provide proof of your credentials, as these will be checked by the council.
