Building Development Dated, November 16, 2012. A copy of approval is attached.
12. Thermal Effects:
Standing Seam roof panels shall be free to move in response to the expansion and
contraction forces resulting from a temperature variation.
The building is cold and not insulated, except for the office areas as shown on the
Assembly to permit movement of components without buckling, failure of joint
seals, and undue stress on fasteners; insulation shall be provide to underside of
the roof to prevent excessive expansion and contraction.
13. Site Conditions:
The following site features and adjacent structures must be considered in the design.
The building will be adjacent to a hill, approximate drop in elevation 5’ to 6’. There are
few trees in the back of the building. The closest building to the new structure is about
The Storage building is separated into three areas; a 54’x28’ a 70’x53’ and 55’x17’ areas. The total
area of the building is calculated to be 6157 sq. ft.
The building will house a very small amount of Hazardous materials; however, the amount is
well below the limits set for “H” use group and specified in IBC table 307.1 (1). A full listing of
these materials may be provided to the contractor upon request. The owner is responsible to
