Contractor shall notify the Architect of any discrepancies or field changes Contractor shall be responsible for all safety precautions and the methods, techniques, sequences or procedures required to perform the work. Contractor shall provide adequate shoring and bracing of all structural members, existing construction and soil excavations as required, in a manner suitable to the work sequence. Temporary shoring and bracing shall not be removed until all final connections have been completed in accordance with the drawings and materials have achieved design strength. Foundations walls greater than 4 feet shall not be backfilled until the floor framing and all connections to the floor framing per these details are complete. CHANGES: No changes to these structural drawings are permitted without written consent of the Engineer. Changes will be billed to the client, owner or contractor at the Engineer's hourly rate.
