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. The following should also be kept in mind:

1. The Drawings are, to some extent, 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.

3. The Electrical Contractor shall review the Contract Documents of the other trades on the Project, and shall coordinate the installation of electrical features with the work of all other trades. In areas such as mechanical rooms where conflicts are likely with structural, mechanical, or other features, the electrical installation shall be performed after the other trades, and arranged to eliminate conflicts.

4. The Drawings and Specifications are complementary to each other and what is called for by one shall be as binding as if called for by all. Discrepancies between any combination of Drawings, specification, and/or field conditions shall be promptly brought to the attention of the Owner for a decision. Failure to obtain such decision before proceeding shall automatically leave the Contractor liable for all expenses necessary to correct the situation to the satisfaction of the Owner.

5. Provide fixtures, devices, equipment, conduit, conductors and accessories indicated on the drawings unless it is specifically indicated that the fixture, device, equipment, conduit, conductor, or accessory is existing.

1.5 GENERAL REQUIREMENTS

A. Provide all work as shown on the Drawings and in these Specifications for a complete, safe, and functional installation.

B. The Contractor is responsible for providing a complete and operating 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 Owner. 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. Unless otherwise noted, all materials shall be of new manufacture and installed before expiration of their shelf life, if applicable.

D. 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.

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

F. 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.

G. 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 at no additional cost to the Government.

H. Any deviations from the installation shown in these Contract Documents, due to a particular manufacturer's requirements, shall be made without additional cost to the Government.

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 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.

For metallic conduits, it shall be assured by making up all joints wrench‐tight and free of foreign materials. Threaded conduits shall enter enclosures by means of threaded hubs or double‐locknut‐and bushing connections. For conduits of one inch trade size and larger, bushings shall be of the insulated type.

B. Conduit joints shall be cut square, reamed smooth, and cleaned of burrs, cutting oil, cuttings, and other foreign materials prior to assembly. Ends shall be capped to prevent entrance of foreign materials during construction.

C. Bends, offsets, and saddles shall be made with factory elbows and fittings, or field‐made with approved benders, to not less than NEC‐required radii.

D. Raceways shall be securely fastened in place at NEC‐required intervals and at each elbow by means of malleable one‐hole straps, clamp‐backs where necessary, two‐hole sheetmetal straps, or other approved devices; all with fastening hardware per Section 26 05 90 “Fastening Hardware”. Wire shall not be used for fastening raceways. The use of adjustable "trapeze" hangers made of U‐channel strut suspended by threaded rods is encouraged for the support of groups of parallel conduits. Conduits shall be secured to each such trapeze by means of the strut manufacturer's standard conduit clamps or by J‐ bolts, with U‐bolts at elbows and ends of runs.

E. Use a junction box at transitions between different types of raceway. Exception: Use one piece manufactured transition fittings between rigid and flexible conduit. Use manufactured transition fitting between conduit and multi‐outlet assembly.

F. Where connecting HDPE conduits is required, the conduit shall be joined by fusion splicing or with other products listed specifically and designed for this purpose.
