SECTION 1.0 - PROJECT SUMMARY

This Construction Scope of Work, together with the Drawings, applicable Saudi Aramco Standards and Specifications listed in the project documents constitute the basis for the complete Work to be performed by the Contractor.

The Scope of Work describes the technical contents of the activities required for the project. It shall be read in conjunction with other Contract Schedules of the Construction Contract and Construction drawings to obtain a complete understanding of the full requirements of the Contract. Contractor shall work on the basis of this Construction Scope of Work, Construction Specifications and Project Drawings as indicated on the Drawing Control Sheet HD-174991. Construction Scope of Work, Specifications and Drawings are complementary and are not to be used separately. Any item mentioned in Scope of Work and not shown on drawings or shown on drawings but not mentioned in Scope of Work shall be of like effects as if shown or mentioned in both.

In case of any conflict between the contract documents, the Contractor shall inform Saudi Aramco Representative and receive his directions before taking any further action.

1.1 Project Description

This Scope of Work identifies the WORK required to construct a new Corporate Data Center for Saudi ARAMCO. CONTRACTOR shall construct/install the facilities in accordance with this Scope of Work. The Project Drawings provide construction locations, dimensions, layouts and installation details. The term CONTRACTOR shall also include all his subCONTRACTORs and vendor. All work will be scheduled to use materials on hand at time of scheduling.

The WORK includes, but is not limited to:

1.1.1 Project Phasing. This project will provide a facility with a raised floor area of approximately 6,000 square meters. The raised floor is divided into four data halls of 1,500 square meters each. It is anticipated that the mission of this facility will require growth over time, so the design concept provides for planned expansion. The sitework, architecture, mechanical and electrical designs allow for ease of future construction. For example, in the areas beside the data halls, all unsuitable subgrade material will be excavated, removed and replaced with select fill so that when the second phase of construction begins no high-vibration excavations will be needed. This idea is repeated in all the other design disciplines. In addition, the critical support infrastructure design is such that the expansion can be accomplished with minimal impact to ongoing operations.

In addition to the data halls, there will be an office component, back of the house critical infrastructure spaces and a security/gatehouse.

1.1.2 Demolition of utilities, pavement, and other structures on the site; site clearing; and disposal of material offsite.

(6)

1.1.3 Site Preparation. The contractor shall survey the site; establish horizontal and vertical controls; provide site clearing and grubbing; remove unsuitable subgrade material; haul in select fill and established grades to +/- 200mm of expected final grades; establish road bases along design centerlines; provide interim storm drainage measures; construct a contractor storage area; construct temporary contractor access gate as needed; establish site security and fencing; excavate the site for foundations; provide final storm drainage; install road network and sidewalks; provide car parking and bus drop-off and bus shelter; and develop utility connections. A contract administrative support trailer area will have been provided by others prior to start of construction.

1.1.4 Contractor shall submit statement method and construction sequencing to minimize the interruption of the normal operation of existing utilities and traffic circulation. Such plans shall be submitted to Saudi Aramco Representative and concerned utilities department for approval prior to start of constru The Contractor shall perform continuous site clean-up during the project and after demobilization and shall adhere to Saudi Aramco Quality and Safety Procedures.

Testing of all materials shall be done at Contractor’s expense by an independent Saudi Aramco approved laboratory or independent laboratory chosen by Saudi Aramco.

Testing and commissioning of all the works by Contractor shall be done by qualified personnel.

1.1.5 Due to the critical nature of the facility, it is designed with redundant power, cooling and communications systems. In addition, redundant systems are housed in separate “compartments” to minimize the possibility of a failure of one system causing a failure in the redundant system or both systems being affected by the same event. There are also sophisticated monitoring, control, fire detection and fire prevention systems.

1.1.6 Saudi Electric Co. (SECO) will be building a new substation adjacent to the facility. This substation will be fed by redundant transmission lines and will have redundant transformers and 15 KV feeders going to the facility. This project includes all cables, conduits and wiring from the SECO provided manholes at the substation fence to the new CDC facility.

1.1.7 The following is the main criteria for the facility: • 6000 m2

of computer raised floor with a maximum of 1500 m2 area in individual compartments

• Buildings constructed to support 100 watts/ft2

computer floor power and cooling density initially with expansion capability up to 200 watts/sf

• Concurrently maintainable: systems allow maintenance of any component without affecting computer room operation

• Compartmentalization: total loss of any support room and internal equipment will not affect computer room operations

• Infrastructure such as piping, conduits, and future equipment connections installed for 200 watts/ft2 computer floor power and cooling density

(7)

• Master plan allows future expansion to 200 watts/ft2

computer floor power and cooling density

• Master plan allows future expansion to 9,000 m2

computer floor area with the same total capacity for power and cooling as 200 watts/ft2 over 6000 m2

• Systems for delivery of critical power to computer floor including generators and UPS populated with equipment with a total capacity less than 100 watts/ft2

Also, additional capacity was built into the design to avoid expansion problems for the following systems:

• Primary Power Substation and Transmission Line Capacity • Central Chiller Plant Area

• Computer Room Air Handling (CRAH) Unit Area • Fresh Air And Humidification Air Handling Systems • Electrical And Instrumentation Conduits

• Cooling Tower Sumps • Water Piping

• Water Tanks • Diesel Tanks

• Remote Power Panels (RPPs)

• Structure For Computer Compartments

1.1.8 The building will consist of precast wall panel exterior walls, and a combination of precast double T and hollow core roof panels.

The data halls will have raised floor for air and power distribution while the balance will be slab on grade.

1.1.9 The electrical system will consist of oil filled exterior transformers feeding interior switchgear. 15 KV feeders will be run underground from the substation to the transformers with overhead cablebus being run from the transformers to the interior switchgear. From the switchgear, feeders are then run via duct bank, trench and cablebus to the various distribution systems.

The main critical support components consist of diesel generators, static UPS systems and flooded cell batteries.

1.1.10 The mechanical support system is comprised of water cooled chillers with cooling towers, a thermal storage tank and CRAH’s in galleries along the perimeter of the raised floor.

1.1.11 Fire detection/protection consists of an addressable fire alarm system, high sensitivity detection, pre-action sprinklers and clean agent gaseous suppression system.

1.1.120 There will be a building management system controlling and monitoring the critical mechanical system and an EPMS system monitoring the critical electrical systems.
