Unless otherwise noted, details, sections and notes contained in the structural contract documents shall be considered typical for all similar conditions even if not explicitly referenced.B. Loads imposed on the base building structure and temporary conditions intended to accommodate construction means and methods are not explicitly considered in this design. The contractor shall advise the Engineer of Record regarding construction loads and temporary conditions imposed on the building structure.C. Verify in the field all existing conditions and dimensions shown on the Drawings and/or affecting the installation of new work.

All dimensions, elevations and conditions shall be verified in the field by the contractors and any discrepancies shall be brought to the attention of the engineer for clarification before proceeding with the affected part of the work. Dimensions and elevations noted in the contract documents as (+/-) and all field conditions shall be verified in the field (V.I.F.) by the contractors prior to the submissions of shop drawings. Upon receipt of shop drawings, the engineer has the right to assume that all field dimensions, elevations and conditions have been verified by the contractors and that the shop drawings accurately reflect such verifications unless stated otherwise on the shop drawings.1.4 BUILDING CODES AND REFERENCED STANDARDSA. 2015 New York State Building CodeB.
