About this file
This package includes construction drawings and specifications for replacement of HVAC units and associated electrical work at the Detroit Ranger District in the Willamette National Forest. The project involves upgrading electrical panels and circuits to support new HVAC equipment, including six air handling units and condenser units. Drawings show existing conditions and proposed revisions to electrical panels, circuits, conduits and conductors. Specifications provide requirements for verifying equipment sizes, breakers and disconnects. The contractor must update panel schedules and drawings to reflect as-installed field conditions. The solicitation is issued by the USDA Forest Service Pacific Northwest Region for the Detroit Ranger District HVAC Replacements project under solicitation number 1240BH21R0019.
