2) Schedule all work at such time and in such a manner to minimize interference and inconvenience to public, staff and operations. Refer to Section 01 10 00, paragraphs 5 and 6 for additional requirements.

3) The Contractor must obtain authorization from the COR as approved by the user before starting any work within any existing area of the building. Protect the area immediately surrounding all areas of work from danger of materials being dropped or dislodged.

4) Carry out work in a manner that will not impose avoidable hardship, danger, or inconvenience to the public or staff. Prior to commencement of work, the Contractor and COR shall jointly survey the construction site and surrounding areas, making permanent record of such existing damage as cracks, malfunctioning utility equipment and fixtures, or other similar damage. This record shall serve as a basis for determination of subsequent damage to these structures and adjacent areas due to Contractor's operations. Any damage, of any nature to these structures and adjacent areas not noted in the original survey but subsequently noted shall be reported immediately to the COR.

5) Isolate the Work area from the occupied spaces. Provide dustproof enclosures, air quality monitoring and other systems to prevent cross contamination between occupied and unoccupied spaces. Occupant safety and comfort should be stressed as important requirements.

8) CRAC units shall remain operational and running during construction. Per Computer Room, one (1) CRAC unit can be disconnected and reconnected at a time, since each room is in a N + 1 configuration. If additional CRAC units are to be mechanically disconnected or shut off, temporary source of chilled water cooling must be provided.

Additionally, to disconnect and reconnect any of the CRAC units will require an ASI. Site will determine the Level of ASI needed.

9) Disruption of Existing Services. The following conditions apply:

(a) Disruption of utility service is not permitted.

(b) DISA Operational State: Disruption of power to critical IT loads is not permitted. Any work involving power panels fed by site technical power require an Approved Service Interruption (ASI) and MOP approval prior to the performance of the work.

3.0 PROJECT WORK ITEM DESCRIPTIONS

The facility scope of work is described by an overall narration of the work to be accomplished, and through listed “Work Items”. Work Items are described, quantified and qualified individual project elements. The Work Items are coded and organized per the ASTM Uniformat II Classification for Building Elements (E1557-97); typically to individual element level (Level 3).

Note: Not every aspect of the scope of work is associated with a corresponding Work Item. The lack of a Work Item does not preclude the requirement to deliver on all aspects of the facility scope of work.

3.1 BUILDING 200 - DECC SAN ANTONIO

1) General

(a) The original 1982 design of Building 200 had a building area of approximately 70,000 square feet. A 1991 design expanded the building by approximately 25,000 square feet. Current building area is approximately 95,000 square feet.

(b) The 1982 building design used variable air volume air handling units for office space heating and cooling. The 1991 building design used multizone air handling units for office space heating and cooling. Data center heating and cooling is provided using Computer Room Air Conditioning units with heat rejection to the chilled water system.

(c) The 1982 Building 200 central plant included a 304 ton chiller, a 399 ton chiller, a 910 gpm cooling tower, a 1200 gpm cooling tower and one 1500 MBH boiler. The 1991 Building 200 central plant included two 140 ton chillers, two 420 gpm cooling towers and one 866 MBH boiler. The 1982 central plant appears to perform as the critical systems whereas the 1991 appears to perform as the non-critical system.

(d) A project in 2009 modified the central plant. Currently there are two (2) 700 ton, 1680 gpm chillers with two (2) associated 700 ton, 2100 gpm cooling towers that supply chilled water to the majority of the building. There is one (1) 150 ton air-cooled chiller that supports the administration areas of the building.

(e) The floor of the building is pier and beam with a significant crawl space under the concrete floors. The floor below the computer rooms is depressed allowing a raised floor for the computer rooms. Additional utility trenches were provided below the computer rooms of the 1982 design to allow routing of hydronic piping above the crawl space.

(f) Several significant changes to hydronic pipe configurations have been made in mechanical rooms and in crawl spaces that are not included on currently available as-built drawings. Several additional hydronic piping and HVAC ductwork changes are currently planned or in progress. Many locations in the building crawl spaces are cluttered with un-documented electrical and piping systems.

2) The work identified for this project includes replacing existing chilled water piping in crawl spaces and raised floor pipe trenches with a new 10-inch chilled loop, provide dedicated outdoor air handling with humidity control for computer rooms and provide a redundant 20 gallon per minute water supply to the critical cooling towers.

SECTION 01 10 00 Page 7

3) The Contractor shall provide and maintain a step-by-step Method of Procedure for all aspects of the project as specified in other sections of this RFP.

x. Applicable engineering studies generated as a result of engineering best practices

5) All welding is to be performed and inspected in accordance with AWS Welding Handbook, Codes and Specifications. Permits and approval from the Site Facility Manager must be provided to solder in the computer rooms and welding outside of the computer rooms.

6) Provide a detailed demolition and installation sequencing accompanied by any necessary special method of procedures. Demolition and installation must be sequenced around maintaining 24/7, 365 operation of the data center and the cooling of the IT loads.

7) Provide controls compatible with BACnet and Modbus per the DISA Standards. <AM#6> Currently the "DISA MINIMUM TECHNICAL SPECIFICATIONS FOR BACnet DIRECT DIGITAL CONTROL SYSTEMS (DDC) FOR HVAC" refers to Delta Controls. The DDC

SECTION 01 10 00 Page 8 network for Building 200 is Johnson Controls not Delta Controls as stated in the specification.
