General Requirements for Foundations and Supports. Contractor shall provide suitable foundations under all new units of machinery. Foundations shall be built up of plates and structural shapes to the dimensions required for satisfactory support, assuring rigidity, freedom from vibration, and designed for secure containment of the equipment in event of crash stops. Foundations shall be constructed to the machinery manufacturer’s requirements, unless otherwise specified in technical specifications or modification. Where dripping water or oil can be expected, the top plates of foundations shall project beyond the edges of the bedplates or bases of units being supported and formed into spill containment/drip pans. Flat bars welded around the edges of the top plates, or combing welded around the deck near the foundation, may be used to retain any leakage. Valve drains shall be provided at the ends or corners of the pans to facilitate fluid removal or recovery. Foundations shall extend beyond the equipment fore and aft or transversely to distribute the load and to avoid excessive weight concentrations. Doublers, insert plates, girders, headers and stanchions shall be fitted and under-deck framing shall be reinforced to support units mounted on deck.
