General and Structural Drawings shall take precedence over Mechanical Drawings. Because of the small scale of Mechanical Drawings, A is not possible to indicate all offsets, fitings and accessories which may be required. Contractor shall investigate structural and finish conditions affecting work and shall arrange his work accordingly, providing such fitings, valves and accessories as may be requi red to meal such conditions without additional cost to the Owner. Each Contractor and Subcontractor shall study all drawings applicable to this work so complete coordination between trades will be affected. Special attention shall be given to points where duds cross other duds or piping, where lights fit into ceilings and where pipe, duds, and conduit pass thru walls and columns.
