The General Conditions, Special Conditions, Instruction to Bidders and all applicable portions of Division 26 – Electrical, apply to the work of this section.

1.2 DESCRIPTION:

The Contractor shall provide a Short Circuit Study, Protective Device Evaluation

Study, Protective Device Coordination Study, and Arc Flash Hazard Analysis for the electrical distribution system as shown and/or described on the one-line drawings or narrative scope including their loads.

The intent of the Arc Flash Hazard Analysis is to determine the hazards that exist at all 3-phase equipment in order to supply information which will aid in the protection of individuals, working on the premises, from electrical hazards.

The Contractor shall collect all required data to perform the analysis and shall verify the accuracy of any owner provided one-line electrical power drawings.

The study will include the creation of Arc Flash Hazard Warning labels specific to each individually identified piece of equipment, new or existing if in need of updating. These labels serve as a guide to technicians and others in the selection of proper Personal Protective Equipment (PPE) when working near exposed energized equipment. The Contractor shall provide all labels conforming to NFPA 70E standards or as directed by the COR.

The Arc Flash Hazard Analysis shall consider operation during normal conditions, alternate operations, emergency power conditions, and any other operating condition that could result in maximum arc flash hazard conditions. The Arc

Flash Hazard Warning labels shall list the “worst case” arc flash hazard condition at each location.

PART 2 PRODUCTS

2.1 ANALYSIS SOFTWARE:

The study shall be performed utilizing the latest version of EasyPower Software or approved alternative. Alternatives must be approved by the Contracting

Officer’s Representative (COR).

2.2 ARC FLASH HAZARD LABELS:

Based on the results of the Arc Flash Study, warning labels shall be produced for each piece of equipment (bus, device, etc.) in accordance with ANSI Z535.4-

2011 (R2017), UFC standards, and the Dobbins ARB design guide. The Electrical

Contractor shall install all field labels and give the COR the option to accompany them during this installation process.

Arc Flash Label Characteristics (Posted information, color, size, and material numbers): The contractor shall coordinate arc flash label, color, size, and materials with the COR prior to beginning work, to comply with existing labels at Dobbins ARB. Posted label information shall match existing labels already present in this facility unless otherwise directed by the COR.

All outdoor labels shall be covered with Clear Polyester Brady B-674 overlayment.

Surface preparation: Use alcohol wipes to clean the surface and then let dry thoroughly before applying the label. If the surface is greasy, use a degreaser first and then go over the area with an alcohol wipe afterwards. Labels should always be applied with firm, even pressure starting at one side of the label and working across the surface of the label with multiple passes. This ensures that the entire adhesive has good contact with the surface. Full adhesion strength will be reached after 24 hours.

The analysis shall be conducted calculating the incident energy using formulas from IEEE-1584. The resulting hazard categories shown on the labels are associated with incident energy levels as defined in IEEE-1584 and NFPA 70E.

SECTION 26 05 74 Page 4

3.1.2 Data Collection:

The contractor shall survey the facility electrical power distribution system for the purposes of recording and documenting all data required to complete engineering studies and one-line diagrams.

Survey shall record data such as: utility information, equipment nameplate/ratings, cable sizes/lengths, overcurrent device nameplates, settings, etc. Once the electrical equipment field data is gathered, the contractor shall forward a copy of the data collection sheets to its Engineer for processing and a record copy to the COR. Any discrepancies identified during the data entry shall be field verified and corrected by the contractor. Engineering judgment shall be used for any equipment data that was unable to be collected and/or that is not within the software component library. All engineering judgments or assumptions shall be noted on the one- lines. No general assumptions of overcurrent device types or sizes shall be accepted. Visual inspection and documentation of all overcurrent devices is mandatory unless inaccessible.

A device point can be described as all 3-phase electrical equipment that will receive an Arc-Flash label as described below. Note: Items listed as additional don’t receive a label but are considered as a data point.

Example Electrical Equipment 600V or Less:

Panel Board - Field Disconnect Switch

Main Distribution Panel - Enclosed Circuit Breaker

Sub Distribution Panel - Automatic Transfer Switch

Switchgear - Manual Transfer Switch

Substation - Motor Control Center

Transformer (3-Phase, All Sizes) - Control Panel

Starter (Combination / Manual) - Bus Duct

Generator - VFD Cabinet

Uninterruptable Power Supply

Each Utility Feed (Additional Item)

3-Phase Motors ≥40Hp (Additional Item)

Example Electrical Equipment Above 600V:

Automatic Transfer Switch - Manual Transfer Switch

HV Switch - HV Starter

HV Transformer

Medium or High Voltage Breaker Compartment

3-Phase Motors ≥40Hp (Additional Item)

Fused Cutout (Additional Item)

Reclosure (Additional Item)

Wire-ways, pull-boxes and junction-boxes will not receive a label under normal circumstances (therefore these items are not a data point unless a label is required). Single phase distribution is not included as a data point.

Existing one-line diagrams and building layout drawings to help facilitate the survey are provided, if available. However, the existing one-lines are not guaranteed to be accurate or complete and all information must be verified during the data collection phase.

On newly designed or renovated electrical systems, the project one-line drawings are included with the bid documents.

The data collection may require removal of barriers, opening of front panels, 504840 DOBBINS AFB SECURITY FORCES FACILITY

SECTION 26 05 74 Page 5 etc. while equipment is energized; an energized work permit is required in such cases. Contractor shall supply a barricade such as tapes, cones or A- frame wood or metal structures intended to provide a warning about limited access to a hazardous area. The barricade shall serve as a physical obstruction that is intended to prevent contact with equipment or energized electrical conductors and circuit parts or to prevent unauthorized access to that specific work area.

If data collection work being performed is located over existing equipment, the data collection contractor shall take precautions to limit the exposure of any equipment or production products from falling dirt, dust or other hazards.

While collecting data, the contractor shall document on the data collection sheets, all breaker and fuse positions (section/position) for panelboards, MCCs, and bus ducts whether they are 1-phase, 3-phase, spare or space.

During the field data collection, the contractor shall not deenergize any electrical equipment without written permission from the COR.

3.1.3 System Analysis:

Perform a comprehensive analysis of facility electrical systems for all 3-phase equipment. The studies shall consider operation during normal conditions, alternate, and emergency conditions which could result in a maximum arc flash hazard. Complete the following engineering studies:

a. Short Circuit Study – A short circuit fault current analysis (three phase bolted fault and single line-to-ground fault) shall be performed in accordance with ANSI standard C37 and IEEE standard 141

(Red Book) for each bus location that will be receiving an Arc Flash

Label.

b. Protective Device Evaluation Study – This study shall be performed to determine whether circuit breakers or fuses have an adequate kAIC rating for the available fault current they must withstand.

Appropriate multiplying factors based on system X/R ratios and protective device rating standards shall be applied. Any problem areas or inadequacies in equipment ratings found shall be listed in table format comparing existing AIC rating to the available fault current.

c. Coordination Study – A coordination study for devices flagged as miscoordinated by the software shall be performed in accordance with

IEEE 242 (“Buff” Book) to determine the proper overcurrent device settings that will provide system reliability through selective coordination while minimizing the magnitude of an electrical arc flash hazard incident. Provide time current curves which graphically indicate the coordination of devices. Any devices that are identified as miscoordinated shall be noted in the study report. The miscoordinated device shall be replaced or settings adjusted to obtain the required coordination. All settings for relays and circuit breakers or fuse sizes (including manufacturer and type) shall be listed in tabular format or on the TCC curve. Any recommendations given shall include existing and final settings.

d. Arc Flash Study – An arc flash study shall be done for each bus location (calculation node) as identified in short circuit study. It shall be done in accordance with the applicable standards IEEE 1584-
