CE response
1. Will you be expecting a warranty on the garage doors themselves or just the accessories and hardware?
CE response - As part of an assembly, the entire system will need to be warrantied.
2. You mentioned the Alarm and interlock to the HVAC "All not working", can you expand on that?
CE response - The existing hvac system is interlocked via a Macurco Combustible Gas detector GD-1s and Macurco Carbon Monoxide Detector/Ventilation controller CM-21A ( 4 pairs which initiate the exhaust systems located on each bay upon detection of up to 25ppm with-in 5 minutes). An alarm notification relay in the CM-21A notifies the alarm system with-in 10 minutes of detecting 200ppm of CO.
system interlocks are not activating as designed. These items are part of the air quality control and the hvac equipment interlocked is EF-1 located in the mechanical room. This EF-1 is also interlocked with the fireman's alarm via the DDC system which starts the fan and runs for 30 minutes to allow any fumes to be exhausted during engine start-up. Refer to sheet D106 sequence of operations for EF-1 and sheet D105 details.
3. Are you aware of any issues with the HVAC (Exhaust Equipment) mechanically, such as motors or fans not operating or do you suspect this is just an issue with the sensors at the individual doors or wiring between the equipment and the doors?
CE response - EF-1 is Operational. The major issue is several control sequences of operations as indicated. Refer to CE response for question
no. 2.
4. It was mentioned you want upgraded railings, can you explain what you are expecting, same size railing of higher quality?
CE response - The contractor shall reference the SOW Existing site description, paragraph e, for bid proposal for railing system.
5. You also mentioned at one point you want all accessories replaced, can you be more specific?
CE response - Please refer to SOW Existing site description paragraphs a-q for project description.
6. Will you provide your fire alarm contractor name and contact information.
CE response - This information will be provided at the Pre-construction conference. This base typically uses Monaco FACP.
