1. Can you please provide the existing curb dimensions for the roof top unit.
Curb dimensions are approximately 24’3-1/2” x 7’1-1/2”. This should only be used as a gross reference. Contractor is responsible for field-verifying all measurements.
2. Please confirm the existing roof top unit does NOT have an electric heat kit added to it.
The RTU does not have an electric heat kit. The building is heated with boilers.
3. Existing Control System is a Tridium Based Controls system, do you want to maintain this system, upgrade to a newer version of Tridium, or upgrade to Metasys?
We cannot specify a brand name; use the most current controls software of selected brand that is compatible with the controllers. Upgrading to a newer version of Tridium would be acceptable.
4. If upgrading Tridium, would you like the graphics to be upgraded or reuse old?
See answer to Question 3 regarding brand name specification. If Tridium is selected as the platform, graphics are to be updated.

Just the controls for Building 1.

All field controllers in Building 1 are to be upgraded.

2 controllers exist. 2 Jaces would be needed to replace them.
