More stringent design standards may be noted on the plans. In the event of a conflict in plans and/or design standard dimensions and/or member sizes, the contractor must utilize the more stringent dimensions and/or member sizes prior to ordering materials, fabrication and/or construction. Design Codes: SCANNED Building Code 2017 (61, Edition) BY Aluminum Design Manual 2015 ASCE 7-10 St. Lucie County Design Loads: Pursuant to FBC Chapters 16 & 20 Ultimate Wind: -150 MPH (FBC Table 2002.4) (45 ps,9 Risk Category: -See attach site specific plan sheet (FBC Table 1604.5) Exposure Category: -See attach site specific plan sheet (FBC 1609.4.3) Additional Load requirements. Structural members supporting screened enclosures are designed for wind in both of two orthogonal directions using the pressures given in Table 2002.4. Each primary member is also designed for a 300 pound load applied vertically downward along any 1 foot of any member, not occurring simultaneously with wind load. In addition to wind pressures, purlins is also be designed for a 200 pound load applied vertically downward along any 1 foot of any member, not occurring simultaneously with wind load. Design Basis: Allowable Stress Design (ASD) =Allowable Strength Design (ASD) divide by safety factor General Requirements: Reproductions of contract drawings by contractor in lieu of preparation of shop drawings signifies acceptance of information shown as correct. and obligates himself to any expense, real or implied, arising from their use. A change to the structural drawings due to the acceptance of alternates and/or substitutes is the responsibility of the contractor and must be submitted to the engineer for approval. The general contractor and each subcontractor shall review the approve construction plans in its entirety and verify all existing conditions prior to the start of any work. All inconsistencies shall be reported to the designer and/or structural engineer, if needed. Should contractor construct the premises in a fashion not consistent with the plans prepared by the designer and/or structural engineer, or in any fashion, change the plans and drawing without the review and approval from the designer and/or structural engineer. Then designer and/or structural engineer shall bear no responsibility or liability for the construction of premises and accuracy of the drawings. Foundation and Earthwork: Applicable only when unsuitable soils are encountered. When unsuitable soils are encountered as specified bearing strata, notify owner's representative/engineer. Soil bearing capacity — 2,000 psf Minimum Provide neat excavation for footing and place concrete immediately after excavation and inspection. Pump water from footing excavation if greater than one inch. Compact all fill to 95% ASTM D698 density.
