To enhance the realism and flexibility of our Police Training, the city of St. Petersburg Police Department is looking for a mobile training structure that allows us to create a variety of rooms and building layouts on demand. Permanent structures limit training and can become repetitive. We are seeking a non-permanent system that can be assembled and disassembled without tools, subcontractors, or specialized labor. The proposed system shall include training on how to perform the setup of the mobile structures. The walls must be reconfigurable, allowing the training environment to experience different scenarios for the officers. These walls must be durable, sturdy, and allow for safe movement throughout the rooms. The walls should be portable where no more than a two-person team can easily carry, setup, disassemble and store the walls. The mobile structure should also include left and right-handed doors, breach able windows, with brackets that merge corners and wall panels effortlessly.
