. >> good morning, kirk dbi and technical services we are proposing a code change to the san franciscog code administrative chapter, to add back in wording allowing us to use the statuses updating the cost schedule. >> currently the building code the valuation is to be determined by the building officials who gives him the final authority on determining that. he can use a cost schedule or you can use the actual cost which ever is greater. the cost schedule that is referenced there may be updated annually based on construction data reported by the valuation engineers. frequently and over quite some time, san francisco unique area and requests come in to clarify and costs for items that are not covered example might be tower cranes or seismic up grades or things like that remodeling things that are not necessarily uniformly nationwide. or covered in these documents. so this change will allow us to continue to gather information from authorized sources that help us put together these costs to help the general public
