Air conditioning and ventilation system
1. Pre - cool fresh air system for guest rooms
As the project budget is limited, the system alternative is considered.
Hyatt shall confirm whether the introduction of direct fresh air to return air chamber of each guest room is acceptable or not.
The introduction of fresh air directly to FCU is complying with local regulation and EIT standard.
The moisture from the fresh air will be dehumidified by the cooling coil of the guest room fan coil unit.
The fan coil unit will be controlled by RCU. The temperature set point will be switched to 26 degree C if the room is unoccupied.
As the FCU is operating all the time, so the fresh air will continuously introduce to the guest room. So the bad smell from the unoccupied room shall not be happened.
2. BMS system
According to Khun Prab confirmation in the meeting on the 29 April, 15, the BMS system will be provided to the cooling system only. [Only AC units]
Regarding to the capability of the RCU networking, the RCU can control the guest room air conditioning system as required by Hyatt.
(Switch room temperature set point to 26 C during unoccupied and also integrated with motion sensor to check guest.)
BAM shall confirm with Hyatt whether the BMS system can be omitted or not.
3. Refrigerant
We would like to get confirmation whether the R22 is acceptable from Hyatt or not.
Electrical and communication system
1. Lightning Protection system
Hyatt has no preference either Faraday or Early Streamer system.
BAM preference is Early Streamer system. So, the construction drawing will be updated according to this requirement.
Note: EECWSP informed that the Early Streamer system does not comply with E.I.T Standard.
2. Fire Alarm System
BAM and Hyatt confirm of using Semi- Addressable system instead of Fully addressable system.
For Semi Addressable system, EECWSP informed that the smoke detector installed in the guest room will be addressable smoke detector with sounder base.
Guest room corridor and public area will be provided with the conventional smoke detector.
3. Hi Speed Internet Access
There are 2 Wireless access point along the guest room floor corridor of each floor.
The number of Wireless access point may increase subject to the obstruction to the internet signal.
There is one data outlet at the working desk of King and Twin guest room.
There is no provision of the data outlet in Suite room at this moment as there is no working desk.
(The data outlet does not show in ID drawing. EECWSP will discuss with P49 to add data outlet in the Suite )
BAM shall confirm with Hyatt whether the wireless internet access can be provided from the guest room corridor and it is not necessary to provided 1 Wireless access point per room.
4. Multi media outlet
BAM and Hyatt shall confirm the requirement of multi media outlet.
5. Telephone System

Additional Shallow Pools next to the main swimming pool and kid pool
1. This additional shall not have a significant impact to the current design.
However, WSP will recheck once there is an input from PL design.
