Historical structures present the challenge of preservation. We are going to perform a site visit at The Helfrich Springs Grist Mill in Lehigh Valley, Pennsylvania. We will gather the needed information, then utilize AutoCAD to create an elevation view of the building while recommending any needed renovations. We will dedicate our time and effort into ensuring that these sites will not crumble to oblivion, but stand as bastions to showcase our innovation as a people.
