All lumber used in construction shall hove a maximum moisture content of 19 %. GENERAL REQUIREMENTS: a. Structural erection and bracing: The structural drawings illustrate the completed structure with all elements in their final positions, properly supported and braced. The contractor, in the proper sequence, shall provide shoring and bracing as may be required during construction to achieve the final completed structure. Contact structural engineer for consultation (not in contract) as required. b. Construction practices: General contractor is responsible for means, methods, techniques, sequences and procedures for construction of this project. Notify structural engineer of omissions or conflicts between the working drawings and existing conditions. Coordinate requirements for mechonical /electrical /plumbing penetrations through structural elements with structural engineer. Jobsite safety is the sole responsibility of the contractor. All methods used for construction shall be in accordance with the latest editions of the IBC /IRC. C. All waterproofing and flashing is the responsibility of the architect and contractor. d. It is the responsibility of the contractor to contact the structural engineer at the appropriate time to perform site observation visits. Observation visits to the jobsite by the engineer are for determination of general conformance with the construction documents and shall not be construed as inspection. e. Though every effort is made to provide a complete and clear set of construction documents, discrepancies or omissions may occur. Release of these drawings anticipates cooperation and continued communication between the contractor, architect and engineer to provide the best possible structure. These drawings have been prepared for the use of a qualified contractor experienced in the construction techniques and systems depicted. f. Existing structures: Contractor shall be responsible for verifying dimensions, elevations, framing, foundation and anything else that may affect the work shown on the drawings. Underpinning, shoring and bracing of existing structures shall be the responsibility of the contractor. 2003 IBC FASTENING SCHEDULE* *THIS IS A PARTIAL SCHEDULE.
