General Demo Requirement Terminate, remove, shut off, cut and cap existing underground and overhead utilities such as domestic water, fire water, storm drainage, sewer, fuel, power, communication including associated manholes, handholes, transformers, switches, poles, steelwork, concrete, pavement and finishes as indicated on the drawings. Re-finishes will match with adjacent materials. Existing utilities not included in the demolition work will be protected from damage. Disassemble and collect salvageable materials as listed in Appendix - B and, transport to 51 CES supply yard near B657. Dispose of all demolished construction debris to off base dump site in accordance with KEGS (Korean Environmental Governing Standards). Any damages to existing pavement, utilities, and other property not specified for demolition shall be repaired by the Contractor at no expense to the government. When contaminated soil is encountered during the course of demolition work, report to the Base Environmental Manage Office (51CES/CEIE). Contaminated soil will be excavated and transported to the base land farm based on the disposal criteria of total petroleum hydrocarbons (TPH) level-800 milligrams per kilogram in accordance with the direction from the Base Environmental Management Office. Any exposed soil caused by excavation will be covered if left over night and, only watertight dumpsters are acceptable for use on site. Contractor will take appropriate measures to minimize dust generation during and after construction until the site is reclaimed IAW KEGS 2-3.i, Table 2-7. Segregation and collection of reinforcing bars from demolished reinforced concrete will not be allowed at the job site. Contractor will coordinate with 51CES/CEIE to take a briefing on stormwater and spill response procedure prior to start any site activities. Contractor will segregate light bulbs and ballasts by brand and type. Florescent lights containing mercury shall be disposed IAW USFD Reg. 201-1 and, KEGS. All removed pad-mounted swithches and transformers will be turned in to Osan Transformer Storage Area (B647) to be properly disposed of them IAW USFK Regulation 201-1, KEGS. If it's weeping/leaking, switches/trasformers should be set on drip pan enough to hold remaining liquid. Also ensure regrigerant (Ozone Depleting Substnaces) from chiller or other HVAC system should be properly removed/disposed. Contact/coordinate with 51CES/CEO through COR for demolition of any utilities, for removal of fuel tank and fuel, asbestos control and removal, tree removal, dust controls, performing EMS & Environmental Awareness Training, removal of fire lines or hydrant and for removal of Communication systems and CATV prior to starting work. Scrap metal, including metal structures, metal roofs, metal fuel tanks, metal railings, metal beams, copper pipes and tubing, and HVAC equipment (chillers and boilers etc.), will be collected by the contractor for disposal and sale through the Osan AB Qualified Recycling Program (QRP) in accordance with DOD Instruction 4715.23, which requires the installation's QRP to receive money through the sale of all installation recyclables. The scrap metal will be turned into the location QRP designates on base.
