PART 1 - GENERAL PROJECT DESCRIPTION

1. The scope of this project includes the dismantling of overhead transformer vault feeding building

904 and transformer vault feeding building 943 and construction of new transformer vault to feed both buildings.

2. The reason for the dismantling of this equipment is that the transformer that feeds building 904 is under the Spanish high voltage overhead line. For safety reasons, it was decided to dismantle the transformer that feeds building 943 due to obsolescence (construction date Oct. 1997).

5.11. Requirements for Drawings:

5.11.1. AUTOCAD Requirements: All designs shall be accomplished in AUTOCAD 2015 or higher and shall be submitted on CD ROM and in one set of Mylar reproducible.

5.11.2. Size of Drawings: The A-E shall use drawing size DIN A-1 841 mm x 594 mm in all cases unless specifically directed to use another size.

5.11.3. Lettering and Shading: The minimum size lettering on all project drawings shall be

2.5 mm high. Make minimum gap between lines equal to one-half the letter height. Shading is not acceptable.

5.11.4. Scales: Locate it directly under the title of each plan, elevation, section and detail and shall be an indication of the scale of the object drawn (example: SCALE 1:100) on the metric system unless otherwise approved. In addition to the conventional scales, and directly to the left of the title block, shall be a series of graphic scales, which shall include every scale used on the sheet. Scales shall be placed in sequence according to size with the smallest uppermost. If it is not sufficient to place all scales on one sheet, each sheet must be treated independently, as the drawings used usually are reduced in size and not always at scaled. For these reasons, it is imperative that graphic scales be shown.

On individual sheets, if the shape of the area dictates, the North symbol can be oriented between these directions to accommodate the site. For example, on drawings having excessive longitudinal but limited lateral dimensions, such as those for roads and railroads, the North symbol can be oriented obliquely to make the best use of available space. All drawings of the same discipline shall be consistent in orientation in so far as practicable.

5.11.9. Geographic Information System (GIS) Master Plan: Coordinate with Geobase Office for requirements on GIS drawings and obtaining initial site plans for GIS survey.

5.12. Requirements for Specifications:

5.12.1. Project Specifications Preparation: Project specifications shall be as brief as possible, definite, and free of ambiguities and omissions, which might result in controversies and claims for additional compensations. For construction projects, which involve interruptions of existing facilities operations or major utility usage, it is the Contractor's responsibility to discuss the required outages and interruptions with the Contracting Officer or authorized representative and operations personnel to establish a construction schedule for these interruptions in the contract specifications. In order to provide conformity in reproduction of specifications, it is requested that all sketches, which are to be bound as a page in the specifications, be drawn on a sheet of A4 page size with 1.25 cm margin on all sides.

5.12.2. Standard Specifications. The guideline for the specifications shall the Unified Facilities Guide Specifications (UFGS). Maximum use shall be made of standard specifications, materials and methods of construction available in Spain (for example, UNE, CÓDIGO TÉCNICO DE LA EDIFICACIÓN, PLIEGOS DE CONDICIONES DEL MOPU, among others). Federal and Military Specifications and other standards such as ASTM, ASME, AASHO shall not be used if the products or the methods described are not available in Spain or are not common practice in the local construction industry, unless there is a requirement for use of such product or method (ie; U.S.

standard electrical devices). In general, the materials shall meet all necessary requirements and be specified briefly in the project specifications.

All equipment shall be installed per the criteria of PTS, applicable codes and manufacturer’s recommendations. Where the word “should” is used in the manufacturer’s recommendations, substitute with the word “shall”.

All electrical raceways under this project shall be installed, to the maximum extent feasible, concealed in walls, above false ceilings or below raised floors, following applicable installation criteria in regulations. The only exception to the installation of concealed raceways is where this would lead to structural damage.

With these materials and following the criteria on adequate proportioning, a level of compactness will be achieved (higher than 250 Kg/cm2) which will ensure total impermeability of the walls and a high resistance to compression. The parts forming the transformer center are the following:

Base Plate: Rectangular slab with channel molding on top for anchoring the vertical panels.

It shall have four semi- die-cut orifices, 120 mm in diameter for entry and exit of cables. The upper portion shall have 4, M-20 nuts embedded in it to mount the eye bolts for manipulation.
