I. Introduction Bhutan Telecom (BT) is the leading telecommunications services provider providing landline telephony service as the sole operator; data (primarily Internet services as the biggest Internet Service Provider) service and domestic & international connectivity; and GSM (mobile) with 3G service (as the market leader) in Bhutan. BT has about 27,000 landline telephone customers, 17,000 fixed broadband subscribers, 230 enterprise customers for its data & connectivity services, and 421,700 mobile customers including that of 3G. The 4G LTE will be launched for trial for 2 sites in the capital Thimphu within this year. It is primarily to serve enterprise customers national and international (in the future) that BT plan to build a 5000 sq. ft. Data Center meeting the standards of Tier-III specifications as per the Telecommunications Industry Associations TIA-942 which comprises mainly the redundant & fully fault-tolerant capacity components including storage, chillers, HVAC, servers, etc. with dual-powered equipment and multiple uplinks guaranteeing an uptime of 99.982%.

II. Size and Location The Data Center shall be built on the two floors: ground and the first; of approximate area of 2500 sq. ft. each making the combined total size of 5000 sq. ft. (approximately) in a 3-floor building which has been recently constructed in BT premise in Phuentsholing, Bhutan. The potential bidders are encouraged to visit the site before the submission of RFP.

III. Scope of Work (in High-level) The Data Center and its infrastructure should be built on a turnkey basis meeting the standards of Tier-III as per TIA-942. Essentially, but not limited to, the Scope of Work shall include design, supply, installation, testing, commissioning and handing over with one year warranty the Data Center with necessary infrastructure like the: interior jobs with painting, precision air conditioning system, fire detection & supression, power, UPS & DG, electrical, lighting, network cabling, multilayer physical security using biometric/smart card, etc. based on access control, IP surveillance, water leakage & detection, rodent repellent, and other incidental and necessary components required to complete Tier-III Data Center specifications in all aspects. Further, the solutions should be proposed to establish very effective and efficient infrastructure monitoring & management systems/practices to ensure Tier-III reliability, availability, Quality of Services and security of information system. While the high-level scope of work has been outlined, Bidders are requested to prepare exact BOM required based on the total area provided in the RFP. IV. Design Considerations

The Data Center should be capable to provide an uptime of 99.982%. It has to be compliant to a Tier-III standards as per TIA-942. The design should be scalable to offer scalability over a minimum period of 7 years and capable to house up to many nos. of 42U server racks (132 nos. if only racks) and cages. Key considerations should be taken in to build for redundancy, scalability, modularity, possibility of isolation and maintainability. The entire Data Center should be designed on the two floors clearly demarcated as per the architecture designs of Ground and First floors. All partitions should be constructed with fire-rated particle board and glass which will increase the aesthetic look. All doors should be 2 hours fire-rated glass. Necessary measures should be taken for making the

PAC should be capable of providing sensible cooling capacities at design ambient temperature & humidity with adequate airflow. As per the requirement, there would be around 130 racks. The PAC should be integrated with the BMS for effective monitoring. PAC system should cool the server rooms and other rooms on the basis of available rooms size and estimated load. 5 nos. of 30 TR floor discharge type PAC can be considered for each floor of Data Center. Out of five units, four units should be active while one can be in standby mode to provide redundancy.
