SAM.gov lists the Solicitation No. as FA286024Q4007, however the Combined Synopsis/Solicitation documents lists FA 268024Q4007. Would the Government please confirm the correct solicitation number for this effort. Government Response: The correct number is FA286024Q4007. 2. Please verify if the backup electric heaters for the (2) 5-ton Trane units are staying or being replaced. Per the SOW “No additional electric heat is required for the replacement equipment”, however the heaters are older and need to confirm the intent is to re-use the existing units.Government response: The intent is to re-use the existing units.3. The indoor Liebert units are on “platforms”, if the new units are the exact same size please confirm re-use of the existing platforms is acceptable, or are they to be replaced with new? Please note that if you want new platforms, that will change this requirement and may change this from a service to construction. It would extend procurement time and make the estimated value more expensive. I would have to look into how this would change the requirement.Government Response: The Existing platforms will be fine if the size of the unit matches the platforms.**Questions and Answers (Updated 4/8/24) - This list will be updated as additional questions are submitted:1.
