These structural calculations are based on conditions and assumptions listed above. If the conditions listed herein are; not met or ars different it shall be brought to the attention of the engineer. Roof Truss and beam system to be engineered by the supplier. This engineering assumes that the building site is dry and stable, a high water table or adverse soils such as plastic clays, fills etc. could cause future flooding, settlement, site instability,, or ether adverse conditions. Verification of and liability for the sail bearing pressure site stability, and all ether site conditions, including site, engineering as required, is the responsibility of others. these calculations and engineering are for the new building structure only and do not provide any engineering analysis of or 11'ability/warranty for the non-structural portions of the building, or the site itself. 'William 'York is the structural engineer only and does not assume the role of "Registered Design professional" or "engineer of Record" on this project. The purpose of these calculations and en ineeri� n is to help reduce structural damage and loss. of life due to seismic activity and/or high wind conditions. The contractor shad verify all conditions, dimensions and structural det�ai�s of the drawing. Multiple use of these calculations is not permitted. All exterior walls shall be sheathed with 7/16" APA rated structural woad panel. Black all hori'zontal edges 1 nominal or wider. Sheathing shall extend continuous from floor to to platy and be nailed at least 4" O.C. along s1*11 plate.
