There will be no other walk-thru. Promptness is required. The bids are due on May 6, 2008 at the above location by 1:00pm. Hardhats are required. A. Scope of Work 1.The contractor shall furnish all of the necessary equipment, labor, supplies, and supervision to replace pipe insulation throughout the GSA steam distribution system. Work is to be performed at various locations throughout the District of Columbia. 2.The contractor shall replace pipe insulation and aluminum jacketing as listed in the table. The old insulation needs to be removed from most of the piping except where noted in the “Description of work” column for only re-insulation and jacketing. The new insulation shall be SSL 850-degree fiberglass insulation. The contractor shall install two layers of 2-inch-thick insulation on the steam line, with top and bottom layers overlapping 50% of their length. The contractor shall install one layer of 2-inch-thick insulation on the pumped condensate and trap return lines. The contractor shall wrap the insulation with.016-inch stucco-embossed aluminum jacketing secured with 3/4" stainless steel bands and wing clips every 18 inches. The expansion joints and valves are not to be re-insulated. 3.The steam and condensate lines shall remain energized during this project. There are approximately 14 tunnel sections and no manholes where piping is to be insulated in this project. Access is gained to the tunnels through personnel openings with ladders and through material access openings. Most of the tunnel entrances are in the sidewalk, although several entrances are in the street. The contractor is responsible for coordinating with the city for lane closures where necessary. The pipes are between floor level and 6 feet high, and are supported by rollers and pipe guides resting on concrete pedestals and steel stanchions in the tunnels. The average temperature of the tunnels is anywhere between the outside air temperature and 130 degrees F. The tunnels have ventilation fans in most areas. There are 120-volt electrical outlets every 40 feet in the tunnels. 4.The contractor shall supply all of the insulation, aluminum jacketing, stainless steel bands with wing clips, and elbow insulation and jacketing for this project. All of the steam line elbows are 90-degree elbows, while the pumped condensate and trap return line elbows are a mix of 90-degree, 45-degree, and miscellaneous-angle elbows. Aluminum end caps are not to be installed or included in the fixed price or unit pricing. Exposed ends of the fiberglass insulation shall be sealed with Childers Chil-Perm WB CP-35 vapor retarder coating or government-approved equivalent, and the jacketing cut and bent over to cover the end of the insulation (see attached picture “jacketing covering end.jpg”). 5.The contractor shall notify the government representative when each item number has been completed so that the completed work can be inspected by both parties. If the completed work has been approved by the government representative, both parties are to sign or initial their approval next to the item number. A dumpster, a job box, and a ladder may be placed at the West Heating Plant. The contractor can work anytime between 6 am and 4:30 pm Monday through Friday.
