7.

Thermal Movements:  Provide for in-plane thermal movements resulting from annual ambient temperature changes of 80 deg F (27 deg C) <Insert temperature>.  Use other values, greater or smaller, whenever justified by climatic conditions at the project site.  If the insulated concrete sandwich wall panels are to include full-thickness concrete sections or metallic connectors between the concrete wythes (surfaces) indicate how wall panel thermal bowing and concrete cracking will be mitigated.

Delete paragraph below if fire resistance rating is not required.  Fire ratings depend on occupancy and building construction type, and are generally a building code requirement.  When required, fire-rated products should be clearly identified on the design drawings.

8.

Fire Resistance Rating:  Select material and minimum thicknesses to provide <one hour> <two hour> fire rating.

Delete paragraph below if window washing system is not required.

9.

Window Washing System:  Design panels for window washing system indicated to resist forces transmitted from window washing equipment pull-out and horizontal shear.  All design criteria for window washing system, including material and equipment, furnished by Owner.

Retain paragraph below if stone faced precast concrete are used on project.

10.

Stone to Precast Anchorages:  Provide anchors, as determined through Owner’s or stone supplier testing, in numbers, types and locations as required to satisfy the performance criteria specified, but not less than the following.

a.

Minimum Anchorage Requirement:  Not less than 2 anchors per stone unit of less than 2 sq. ft. (0.19 sq. m) in area and 4 anchors per unit of less than 12 sq. ft. (1.1 sq. m) in area and for units larger than 12 sq. ft. (1.1 sq. m) in area, provide anchors spaced not more than 24 inches (600 mm) o.c. both horizontally and vertically, all located a minimum of 6 inches (150 mm) from stone edge.

Delete paragraph below if units are not used in parking structure to resist impact load.

11.

Vehicular Impact Loads:  Design spandrel beams acting as vehicular barrier for passenger cars to resist a single load of 6,000 lbs  (26.7 kN) service load and 10,000 lbs (44.5 kN) ultimate load applied horizontally in any direction to the spandrel beam, with anchorages or attachments capable of transferring this load to the structure.  For design of these beams, assume the load to act at a height of 18 inches (460 mm) above the floor or ramp surface on an area not to exceed 1 sq. ft. (305 mm²).

1.5

 SUBMITTALS

A.

Product Data:  For each type of product indicated.  Retain quality control records and certificates of compliance for 5 years or period of warranty, whichever is greater.

B.

Design Mixes:  For each concrete mix along with compressive strength and water-absorption tests.
