PROFESSIONAL ENGINEERING SERVICES TO CONDUCT AN ARC FLASH ASSESSMENT AT PUBLIC UTILITIES FACILITIES

2026-11-03

The City of Lenoir is requesting Statements of Qualifications of individuals to provide Professional Engineering Services to conduct an arc flash assessment that meets the requirements of the current standards in accordance with 29CFR1910 . 132 .( d )( 1 ), NFPA 70E . The procedures for analysis will require developing electrical system impedances using source impedances obtained from Duke Energy or Blue Ridge Energy and a review of the most recent field data . An up - to - date single line diagram of the facilities will need to be created to perform arc flash calculations to determine incident energy levels . From incident energy levels , risk categories and personal protective equipment ( PPE ) requirements can be determined . The analysis needs to be completed at : 1 . Lower Creek Wastewater Treatment Plant 2 . Sewer Collections Facilities serving Lower Creek WWTP a . Acorn Square WW Lift Station b . Arrowood WW Lift Station c . Cajah ’ s Flume Meter d . Dula Miller Hill WW Lift Station e . Gamewell WW Lift Station f . Georgetown WW Lift Station g . KFC WW Lift Station h . Summer Hill WW Lift Station i . Summit WW Lift Station j . Town and Country WW Lift Station k . Valmead WW Lift Station 3 . Gunpowder Creek Wastewater Treatment Plant 4 . Sewer Collection Facilities serving Gunpowder Creek WWTP a . Cypress Street WW Lift Station b . Meadowood WW Lift Station c . Spring Street WW Lift Station d . Fir Street WW Lift Station e . Quarry Estates WW Lift Station f . Sawmills Flume Meter 5 . Lake Rhodhiss Water Treatment Plant 6 . Water Distribution Facilities a . Cajah ’ s Mountain Tank site b . Hudson Booster Pump Station and Tank site c . Whitnel Tank site d . Finley Tank site e . Indian Hills Booster Pump Station f . Indian Hills Tank site g . Bushtown Booster Pump Station h . Bushtown Tank site i . Blue Ridge Forest Booster Pump Station j . Blue Ridge Forest Tank Site STATEMENT OF SERVICES The selected Professional Engineering firm is responsible for providing services that meets the requirements of the current standards in accordance with 29CFR1910 . 132 .( d )( 1 ), NFPA 70E associated with the project including , but not necessarily limited to : 1 . Collect field data for service transformers ’ nameplate data , generator nameplate data , short circuit and equipment duty ratings , types and sizes of all protective devices , and conductor sizes and lengths for all feeders and necessary branch circuits . 2 . Enter field data and create a one - line model in an appropriate power analysis system database . 3 . Perform a preliminary short circuit and equipment verification study to verify the facility ’ s equipment is rated to safely handle short circuit currents without creating hazardous conditions . 4 . Calculate impedances using circuit sizes and configurations , transformer nameplate data , generator nameplate data , and source impedance data obtained from Duke Energy ’ s or Blue Ridge Energy ’ s electric system . 5 . Determine system operating modes and conditions that can impact short circuit currents and arc flash hazard energy levels . 6 . Perform and arc flash analysis to determine arc flash energy levels , arc flash protection boundaries , and PPE requirements . 7 . Review protective device coordination to determine if arc flash hazard energy levels can be reduced . 8 . Prepare and provide a detailed report on findings of the analysis . 9 . Provide two ( 2 ) hard copies and one ( 1 ) electronic copy in . pdf form of the analysis report . 10 . Create and install arc flash informational labels for appropriate equipment identified and studied for incident energy and PPE requirements to satisfy FNPA 70E .
