This program will develop a construction cost model to accurately evaluate the relative construction cost of a multi-residential building constructed using 6 different construction materials: wood framing, light gauge steel framing, masonry walls/precast floors and ceilings, precast construction, ICF walls with precast plank and ICF walls with ICF floors and ceilings. Both builder’s risk and property insurance will be addressed as well as the 10-year cost to the eventual building owner.
