(iii) This solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Regulation Circular Vol. 60, No.180 dated 09/18/97. (iv) The applicable Standard Industrial Code (SIC) 1500. (v) Pentagon Heating & Refrigeration Plant has ten (10) 3,750 tons (each) York chillers.Pentagon Heating & Refrigeration Plant uses river water as condenser water after straining. The chiller plant is divided up into two headers and even side and an odd side. The contractor shall supply all supervision, labor, equipment and material to clean condensers, by inserting apowered brush, against the normal direction of flow, into each of the 4,030 condenser water tubes for five (5) of the ten (10) chillers. The condensers are two pass units, with hinged covers and baffles on both of the water boxes. The shell has an internal diameter of 6' and a length of 16' and is rated at 250 psig. The condenser is design to handle 11,250 g.p.m. of river water at 82 F with a pressure drop of 19'. The contractor shall perform the following work: 1. The Pentagon Heating & Refrigeration Plant will close; lockout and tagout, the inlet and outlet water valves for each condenser and drain the condenser water. Contractor personnel shall be required to attach their own personal locks onto the locked out and tagged out valves. The contractor should expect some minor seepage of water, because there may be a small amount of water continuously leaking through the valves and the contractor shall be required to work under these wet conditions. 2. The contractor shall provide and install scaffolding for gaining access and to use as a work platform for each of the condenser heads. The scaffolding shall be strong enough to withstand weight of contractors' personnel and equipment and shall be built according to OSHA regulations. The contractor shall unbolt the two water boxes (heads) for each condenser. During tube cleaning a positive means of preventing dirt and debris from entering the condenser water discharge line shall be installed. This shall be removed before the water box covers are reinstalled. The contractor shall provide a 2" water hose to the bottom 2" drain connections at each of the water boxes to drain off dirt and water pushed out of the tubes. The contractor shall route his hose to the nearest floor drain or as designated by the plant manager or his representative. 3. The contractor shall use electric or air pressure operated tube-cleaning machines, with brush and hose attachment. The contractor shall make liberal use of water for softening and pushing scale and dirt from inside of the tubesand from a water box on the opposite end when cleaning tubes. Contractor shall use a positive means of stop on the brush-hose assembly so that brush does not over travel inside the tube on the opposite end. Total travel shall be kept to 16 feet, including the tip of the brush, however the exact total travel will be given to the contractor after the water box is removed. Condenser tubes are copper, 16 feet in length and 3/4 inch in outside diameter. However, the contractor shall check size of the tubes before ordering any material. The contractor shall use 5/8-inch X 16 gauge nylon brushes, suitable for copper tube cleaning. A new brush shall be used after cleaning 100 tubes to ensure proper contact and cleaning. The contractor shall supply his own ground fault protected electric extension cords and/or air and water hoses for connecting his tube cleaning machine to the appropriate sources of motive power. 4. Contractor shall furnish and install new gaskets for the water boxes after removing the existing gaskets and cleaning the gasket surface. The new gasket shall be same in size, material, style and installation as existing. The contractor shall wire brush water boxes, heads, and baffles. Clean all inside surfaces of the water boxes and baffles and epoxy paint any bare or this spots. The contractor shall clean the tube sheets with a nylon brush and water. Some tubes may be plugged with marine life or debris and may prevent the brush from passing through the tube. In this event the tubes shall be cleared using a rod to clear the blockage. After the blockage is removed the tube shall be brushed as outlined above. The contractor shall exercise caution to prevent scoring of the copper tubes when rodding out blockages. 5. The contractor shall use care to prevent wetting of adjacent 4160 kV chiller control panels, and the instruments (transducers, probes, etc.), electric equipment and electric motors. The contractor shall cover the adjacent chiller control panels, instruments, and electric equipment and motor with 6 mil plastic sheets before starting work. 6. After finishing tube cleaning for a chiller, the contractor shall allow up to four (4) hours for inspection of the tubes by the Pentagon Heating & Refrigeration Plant personnel. Each tube may be inspected by shining bright light or by inserting a white cloth, and if any debris is found in the tubes, the contractor shall be required to clean those tubes again. He shall be required to repeat the tube cleaning process for any number of times until they are clean. 7. After cleaning tubes for a chiller, the contractor shall install new gasket material and reinstall the baffles and close the two water boxes back on the condenser. The contractor shall tighten all nuts for the water box access covers and fill the condenser with water from the city water fire hydrant. If the water box gasket shows any water leaks under a water pressure of 80 psig, then it shall be contractors' responsibility to tighten bolts or reinstall the gasket or both. 8. The contractor shall start work during the week after receiving the notice to proceed and shall complete all work within three (3) weeks. Only one machine will be taken out of service for cleaning at a time. No machine shall be down for tube cleaning for more that five (5) calendar days. 9. The contractor shall comply with OSHA safety regulations. Also, the contractor shall follow plant safety and security regulations. The contractor shall keep his work area clean and safe from tripping hazards at all times. Entrance to the Pentagon Heating & Refrigeration Plant is restricted.
