The scope of this submittal has been limited to an engineering analysis and design of the primary components of the canopy structure in accordance with the 2015 International Building Code. • All fl ashings, coatings, membranes and sealants are by the contractor. Design Criteria: Roof: 25 PSF Wind: 85 MPH, Exposure B, I = 1.0 Seismic: Sds (Seismic Design Category D) = 0.8334, R = 6.5,1= 1.0 525 Columbia Street NW, Suite 201 Olympia WA 98501 t. 360.709.0807 f. 360.786.8474 STRUCTURAL NOTES These structural notes apply to all structural components of the primary structural systems. Any discrepancies found among the drawings, these notes and the site conditions shall be reported to the Engineer of Record, who shall correct such discrepancy in writing. Any work done by the Contractor after discovery of such discrepancy, but prior to correction of such discrepancy, shall be done at the Contractor's risk. • The Contractor shall field locate and identify all site utilities prior to performing any site excavation or demolition. The Contractor shall be responsible for all safety precautions and methods, techniques, sequences or procedures required to perform the Contractor's work. The Consulting Engineer has no overall supervisory authority or actual and/or direct responsibility for the specific working conditions at the site and/or for any hazards resulting from the actions of any trade contractor. The Consulting Engineer has no duty to inspect, supervise, note, correct, or report any health or safety deficiencies to the Owner, Contractor, or other entities or persons at the project site. • It is the Contractor's responsibility to verify all field measurements and site conditions prior to fabrication of any structural elements. No allowance will be made for any items incorrectly fabricated or installed due to failure to perform such verification prior to commencing work. Contractor initiated changes shall be submitted to the Consulting Engineer in writing for approval prior to fabrication, construction or field modification. Changes shown on shop drawings only will not satisfy this requirement. Non-structural building systems, including: flashings, membranes, coatings, sealants or ventilation are not the responsibility of the Consulting Engineer, CONSTRUCTION STABILITY The design, adequacy and safety of erection bracing, shoring and all temporary supports is the sole responsibility of the Contractor, and has not been considered by the Consulting Engineer.
