<br />The Contractor shall coordinate with the building department for all building department required inspections.
<br />TEMPORARY SHORING AND BRACING
<br />The Contractor shall provide temporary bracing as required until all permanent connections and stiffening have
<br />been installed. The Contractor is responsible for the strength and stability ofall partially completed structures
<br />including but not limited to concrete or masonry walls, steel framing and erection aids. The Contractor shall, at
<br />their discretion, employ the aid of a licensed Structural Engineer to design all temporary bracing and shoring
<br />necessary to complete the work described in these contract documents. The Contractor shall be responsible for
<br />all required safety standards, safety precautions and the methods, techniques, sequences or procedures
<br />uired in performing their work. For concrete construction refer to ACI 318 Section 2611.2"Removal of
<br />Formwork".
<br />SAFETY PROCEDURES
<br />Contractor shall beresponsible for all safety precautions and the methods, techniques, sequences or
<br />procedures required to perform the contractor's work. The Structural Engineer has no overall supervisory
<br />authority or actual and/or direct responsibility for the specific working conditions at the site and/or for any
<br />hazards resulting from the actions ofany trade contractor. The Structural Engineer has no duty to inspect
<br />supervise, note' correct, or report any health orsafety deficiencies to the Owner, Contractors, mrother entities
<br />orpersons atthe project site.
<br />SHOP DRAWINGS AND SUBMITTALS
<br />SHOP DRAWING & SUBMITTAL REVIEW (including Deferred Structural Components)

<br />submittals for items shown on SEKdocumentx. Submittals for Deferred Structural Components will receive
<br />cursory review bvSERfor loads imposed onprimary structure. SEkwill review shop drawings for general
<br />conformance with design concept of the project and general compliance with the information given in the
<br />Structural Contract Documents. Review of submittals does not constitute approval or acceptance of
<br />unauthorized deviation from Contract Documents.
<br />Corrections or comments made on shop drawings during this review do not relieve Contractor from
<br />compliance with the requirements ofthe plans and specifications.
