About this file
This is a Selective Demolition specification section (024119) for the KRRD District Office HVAC Repair project at Sequoia National Forest. The specification establishes requirements for the selective demolition of the KRRD District Office HVAC system and associated utilities.
Key execution requirements include: recording existing conditions through digital preconstruction photographs; maximizing salvage and recycling of demolished materials through dismantling and material separation; protecting relics, antiques, commemorative plaques, and historical artifacts as USDA Forest Service property with prior architect notification and acceptance before removal; and removing and disposing of all other materials. Contractors must comply with applicable demolition codes and regulations, obtain required permits, prohibit explosives use, prevent catastrophic structure collapse, maintain temporary barriers and security devices, and minimize dust production without using water that causes ice, flooding, sedimentation, or pollution. Coordination with utility companies is mandatory with notification before work begins. Contractors must protect utilities remaining in service, mark them with highly visible identification tags, provide 7 days' notice before disrupting life safety systems and 3 days' notice before disrupting utility branches. Work cannot begin until receipt of notification to proceed from the USDA Forest Service Contracting Officer Representative (COR). Weekly debris removal and site cleanup are required, with spillage and wind-blown debris cleaned from public and private lands.
