It is the responsibility of each Contractor and Subcontractor to leave necessary room for other trades. No extra compensation will be allowed to cover the cost of removing conduit, ducts, or equipment found encroaching on space required by others. MINOR DEVIATIONS For the purpose of clarity and legibility, Drawings are essentially diagrammatic although size and location of equipment are drawn near to scale wherever possible. Verify Contract Document information at site. Drawings indicate required sizes and points of termination of ducts and suggested routes. It is not the intention of Drawings to indicate all necessary offsets. Install work in a manner to conform to structure, avoid obstructions, preserve headroom and keep openings and passageways clear.
