PART 1 GENERAL

1.1 SCOPE: SECTION 26 05 10 – BASIC MATERIALS AND METHODS

A. This Section covers selection and installation basic electrical material and methods.

1.2 GENERAL

A. Provide all Work as shown on the Drawings and in these Specifications for a complete, safe, and functional installation. All Work shall comply with the latest edition of the National Electrical Code (NEC).

B. The Contractor is responsible for providing complete and operating systems in the facility. The intention of the Contract Documents is to include all labor and materials, equipment, and transportation necessary or reasonably inferable as being necessary for the execution of the work.

Where minor adjustments of the work are necessary for purposes of fabrication or installation of items, or resolution of conflicts between items within the intent of the Contract Documents, the Contractor shall make such adjustments at no added expense to the Government. Where such adjustments affect functional or aesthetic design of the work, they shall first be submitted to the Contracting Officer for review and approval.

C. Obtain and pay for all permits, plan reviews, and inspections required for the Work covered by this Division of the Specifications.

D. Unless otherwise noted, all materials shall be of new manufacture, and installed before expiration of their shelf life, if applicable.

E. Materials and equipment are to be those of major and reputable manufacturers with ability to render competent and thorough service through local and regional organizations capable of expeditiously providing service, parts, and assistance.

F. Materials of similar nature, style, function, purpose, and/or appearance shall be like products from the standard product line of the same manufacturer.

G. All products shall be listed and labeled by an approved national testing laboratory for their intended use and location in all cases where such products are listed and labeled. Where no product listed by an approved national testing laboratory for the application is available, provide certification of performance, function, and rating from an independent testing agency or laboratory approved by the Contracting Officer.

H. The omission of express reference to any parts, supplies, services, or facilities necessary for, or incidental to, a complete installation shall not be construed as a release from furnishing such items.

I. Verification is required of all equipment sizes and locations prior to the ordering or installation of connection materials and disconnecting equipment to ensure that the power connections are of the proper size and type, and in the proper location. Verify all electrical loads (voltage, phase, full load amperes, number and point of connections, minimum circuit ampacity, etc.) for equipment furnished under all divisions of this specification, by reviewing respective shop drawings furnished under each division. Meet with each contractor and subcontractor furnishing equipment requiring electrical service and review electrical characteristics. Report any variances from electrical characteristics noted on the drawings with the Contracting Officer before proceeding with rough work. Obtain and review the equipment shop drawings to determine particular final connection requirements before rough-in begins for each equipment item.

J. All materials shall be installed in a neat, orderly, and secure fashion, as required by these specifications and commonly recognized standards of good workmanship, for which the Contracting Officer’s judgment shall be final. The norms for execution of the work shall be in conformity with NEC Chapter 3 and the National Electrical Contractors’ Association “National Electrical Installation Standards”.

K. Electrical equipment shall be installed in spaces that are accessible and in a manner that allows for maintenance and replacement. Entries into spaces shall allow for the passage of equipment.

1.3 SUBMITTALS

A. Prior to the purchase of any materials or equipment, the Contractor shall submit for acceptance data completely describing all items intended for use in the work. This data shall include the manufacturer and identifying number or nomenclature; the manufacturer's published data as to size, capacity, power requirements and dimensions, shop drawings; and such other information as necessary to properly describe each item. Catalog cuts fulfilling these requirements will be considered appropriate for this application. Such "commodity" items need not be submitted if they are being provided exactly as specified, and are so certified in the Index section of the submittal.

1.4 DRAWINGS

A. Unless otherwise indicated, drawing symbols conform to the applicable standards of ANSI. The Drawings (or Contract Drawings) rely heavily upon symbolic representation of the features shown, and represent exact details only so far as indicated.

1. The Drawings are diagrammatic and are not intended to show exact details.

2. Dimensions scaled from the Drawings may vary due to tracing tolerances, printing distortion, field conditions, field changes, and other factors. For these reasons, it shall be the Contractor's responsibility to field verify dimensions that pertain to his work. The Contractor shall make minor relocations where necessary to resolve conflicts or present a uniform appearance. The Drawings show exact location of electrical features only where specifically dimensioned.

B. All existing equipment left remaining shall be maintained in service. When encountered in work, whether shown on the drawings or not, protect, brace and support existing items. If existing active electrical services are encountered that require relocation in order to execute general, electrical or mechanical work, relocate services as required and as directed without additional cost to the Government. Any equipment, which is not specifically indicated for removal or is not shown or noted, shall remain in service.

1.5 AS-BUILT DRAWINGS

A. The Electrical Contractor shall at all times keep a current set of Contract Drawings on the Project site. This set shall be kept in good condition, and shall be neatly and accurately marked to show the as-built condition of the electrical installation.

B. The field-marked set of drawings described in (A.) shall be made available to the Contracting Officer or their authorized representative for spot-checking at every inspection.

C. Upon completion of the Project, the field-marked set of Drawings described in (A.) shall be forwarded to the Contracting Officer, along with any supplementary drawings, sketches, notes, or other materials necessary to completely describe the as-built condition of the electrical installation.

1.6 REPAIR OF EXISTING FEATURES

A. Where existing or previously completed building surfaces or other features must be cut, penetrated, or otherwise altered for the installation of electrical features, such work shall be carefully laid out and performed, and any subsequent patching or repairs that it necessitates shall be performed by skilled mechanics of the trades involved. All cutting and patching shall be done with materials similar in appearance, function and rating to those in the existing construction. The patch shall not be noticeable and the contractor shall take such steps as painting any wall disturbed from corner to corner, top to bottom.

1.7 REMOVAL OF EXISTING ELECTRICAL FEATURES
