This Senior Design project concerns the development of a 35% design for a covered storage facility for the U.S. Air National Guard base located in East Granby, Connecticut. A partially enclosed facility is required to mitigate the effects of weather and temperature fluctuations on various emergency vehicles and equipment which are currently experiencing wear due to their exposure to the elements. In particular, the Air National Guard requires a section of fully enclosed and heated storage to prevent damage to electrical components within the Mobile Emergency Operations Center vehicle. As per the U.S. Air National Guard's square footage authorization, the facility will have 4,000 square feet of storage space with another 1,000 square feet of fully enclosed heated parking. The scope of the project calls for the design and load rating of a steel frame structure as well as the development of a cost estimate and a construction schedule. The details of the 35% design are packaged in a set of design drawings laying out the chosen dimensions and sections of the facility. Three alternative steel frame designs have been developed to address the problem. One of these designs was ultimately selected based on criteria such as the impact of construction cost, expected maintenance, and the input of the project's end users.
