• <br />Sewage Disposal Package Plant <br />• Foundation Type — Monolithic (Turndown) Structural Slab. (p. 6) <br />• Structual Fill — Minimum of 24- inches below foundations. The existing fill <br />materials are not suitable for reuse as structural fill. With careful moisture control <br />and proper compaction, the native clay soils may be reused as structural fill. <br />Imported structural fill should consist of pit -run, crusher fines, CDOT Class 6 base <br />course, or other granular material approved by the engineer. (p. 6) <br />• Nfaiinrum Allowable Bew-ing Capacity— 1,500 psf. (p.6) <br />• Subgrade Modulus — 150 pci for native clay soils. 250 pci for pit -run, crusher fines, <br />or CDOT Class 6 base course. (p. 6) <br />Hoist Building <br />■ Formdatlonn Type — Shallow Foundations, Driven Steel Piles, Screw Piles/Helical <br />Pier. (p. 6) <br />Shallow Foundations <br />• Structural Fill — Minimum of 48- inches below foundations. The existing fill <br />materials are not suitable for reuse as structural fill. Imported structural fill should <br />consist of pit -run, crusher fines, CDOT Class 6 base course, or other granular <br />material approved by the engineer. (p. 7) <br />• Maximum Allowable Bearing Capacity -- 2,000 psf. (p. 7) <br />• Subgrade Moduhns — 250 pci for pit -run, crusher fines, or CDOT Class 6 base course. <br />(p• 7 ) <br />Driven Steel Piles <br />■ Pile Type -Minimum 10'/4 inch diameter pipe piles or HP 10X57 piles. (p. 8) <br />• Anticipated Length — 24 to 32 feet. (p. 8) <br />■ Axial Capacity — 40 tons for 10% inch pipe piles or HP 10 -57 piles without pile load <br />testing.(p. 8) <br />Screw Piles /Helical Pier <br />• Anticipated Length — 24 to 32 feet. (p. 9) <br />• Axial Capacity — Dependent upon pile load testing; however, 20 to 60 tons is <br />anticipated. (p. 9) <br />Other Foundation Criteria <br />• Lateral Earth Pressure — 50 pcf (p. 9) <br />• Seismic Site Class — Site Class D (p. 9) <br />
