This document shall govern for any conflicts that may occur with the requirement for the piers between the FDA and this document. Through Expansive Soils. Piers that extend through expansive soils may be subjected to tension loads caused by soil friction on the shaft as the soil expands. The FDA will give either recommended pier design tension or minimum shaft tension reinforcement and minimum bell size to anchor the pier when expansive soils cause pier tension. Pier tension reinforcing should be sized for net load obtained by subtracting the pier load due to the building dead weight from the tension due to soil heave. Pier Diameters. Minimum pier diameters are 18 inches for piers up to 40 feet in depth and 24 inches for piers deeper than 40 feet. Sizes. diameters should be specified in increments of 6 inches. Size bells for dead load plus the portion of live load that acts continuously. Vertical Loads. Pier loads should be computed only to grade (weight of pier, bell and earth above base of footing will be taken into account in determining "net" allowable bearing pressure given in the FDA. Lateral on Grade Beams and Piers. Ties between piers may be necessary in seismic regions as required by the IBC. The structural designer shall see the FDA and/or consult with the geotechnical engineer for recommended lateral soil design parameters. General Superstructure Requirements. The system shall provide vertical and lateral load carrying capacity and shall provide durability, maintainability and cost effectiveness. Roof openings and all supports for ventilators, fuel tanks, electrical bus ducts, unit heaters and other mechanical equipment must be detailed or adequately described on the drawings or in the specifications. The structural designer shall ensure that all mechanical and electrical equipment is properly supported and that architectural features are adequately framed and connected. Steel Superstructure Construction Requirements. Structural Steel Framing. General. The structural system shall be designed for both the vertical and horizontal loads required by UFC 3-301-01, but not less than any dead loads and live loads specified in this document. Structural calculations shall be submitted for all vertical, horizontal and connection designs. Structural Steel Notes. Provide superstructure structural steel notes on the contract drawings as shown in CESPA Standard Structural Drawing Sheets.
