PPCC DQ 16-779 Art Classroom Ventilation Question Answer .pdf

This is a Question and Answer document related to a state and local contract opportunity for art classroom ventilation work at Pikes Peak Community College (PPCC) in Colorado, specifically for projects designated as DQ 16-779, CON 1573, and CON 1574. The document addresses technical specifications and design clarifications for ventilation system installation at PPCC's Centennial Campus. Key project details include exhaust fan placement restrictions, ductwork routing requirements, and conflict resolution between new and existing mechanical systems. The document references Addendum #1, which contains maps, drawings, letters, and supporting documentation available through PPCC's upload portal, providing bidders with detailed design guidance and spatial constraints for the proposed work.

The Q&A responses establish specific technical parameters for the ventilation installation, including that the exhaust fan location at Centennial Campus cannot be repositioned to the north due to structural coordination constraints, with the fan set back 10 feet from the low parapet. Regarding ductwork placement, contractors are instructed to position new ductwork as high as possible in the space while avoiding direct contact with structural elements to minimize vibration transmission. Where conflicts with existing ductwork occur, the new 20x10 ductwork (or equivalent) should be routed to the south of existing systems to avoid interference. These technical clarifications in the addendum serve to guide bidders in preparing accurate proposals and ensuring compliance with PPCC's engineering and operational requirements.
