19-RFT-0078-00B - Air Handling Unit Replacement, Yellow Wing, Brockville Campus

It is important that St. Lawrence College provide a healthy, safe and welcoming environment for students, staff and visitors to the College. It is therefor important that this replacement be carried out proactively to avoid extended shut downs in the systems created by a major failure. The work also needs to be completed during the “summer break” for students and as early in the spring as possible to reduce the impact on the occupants.  
Once this issue was identified during air handling unit condition assessments, an Engineering firm was contracted to investigate further and a remedial plan has been created to repair the situation.  
 
The intent of the project is to have a qualified contractor replace the air handling system as outlined in the specifications and drawings, including but not limited to:

• Supply new and install a new air handling unit (supply air fan, cooling coil, and the respective casings) and remove existing unit and properly dispose of same
• Air Balance testing before removal of existing system and upon completion of work
• Replace OA/EA dampers with thermally broken, gasketed dampers and install new filters
• Supply and install all equipment, materials and labour to connect all electronic equipment to existing BAS
• Recommission existing associated controls and replace all existing pneumatic controls on the existing unit with digital and monitor and/or control from existing Johnson Controls building automation system.
