Project Overview and Understandings In 2012, Consultant prepared the Durham Facility Solids Building Odor Control Project Conceptual Design for District. The recommended plan from the study involved separating air sources into three categories and treating them through different methods depending on the odor strength. The first phase of the recommended plan involved the installation of new sand media biofilters to treat high strength odor sources at the Solids Building and Struvite Recovery Facility and was completed in Phase 2 of the Project consists of installing new heating, ventilation, and air conditioning (HVAC) equipment to provide custom design ventilation to various spaces in the solids building with the new NFPA 820 (2012) standard in mind. The Project also includes separating the existing duct work system and installing new duct work to vent very low strength odor sources directly to the atmosphere and to direct low strength odor sources to the existing chemical odor scrubber.

The purpose of the current amendment is to provide bidding and construction services for the Project, involving construction of new HVAC equipment, MCC installation, scrubber modifications, replacement of the Solids Building roof and other associated improvements to separate low and very low odor sources.
