USDA, Ames, IA

Statement of Work

Project Requirements:

Background:

The Standard for Electrical Safety in the Workplace, NFPA 70E states in Article 130.5 that an arc flash risk assessment should be reviewed every five years or whenever there is a significant change in the electrical system. There have been three (3) arc flash studies performed on different systems on campus at different times in the past:

Building 3, Building 4 --- Performed October 2010

Building 20/24 --- Performed January 2007

Buildings 21, 9, 402, 401MB, 153, 154, 155, 156, 5, 10, 11, 417(C3), 418(C4), 419(C5), 420(C7), 421(C8), 406(A3), 407(A4), 408(A5), 409(A6), 410(A7), 411(A8), 412(A9), 520, 403, 500, 510, 445(Y2), 22, 440(H1), 441(H2) –Performed October 2010

Buildings 152, 400, 415(C1), 416(C2), 404(A1), 405(A2), 413(B1), 414(B2) and 444(Y1) have been demolished since the last evaluations.

Scope:

The general objective of this project is to provide an arc-flash analysis to determine the incident energy levels at specified working distances from selected electrical equipment, which can be used to select the appropriate Personal Protective Equipment (PPE) to be used when working within the flash protection boundary. Contractor shall provide all labor, tools, materials and inspection equipment as necessary for the on-site data collection for equipment/electrical circuits. Contractor shall review the existing reports from the previous studies for Buildings 3, 4, 5, 9, 20, 21, 24, 153, 154, 155, 156, 401MB, 402, 417(C3), 417(C3), 418(C4), 419(C5), 420(C7), 421(C8), 406(A3), 407(A4), 408(A5), 409(A6), 410(A7), 411(A8), 412(A9), 520, 403, 500, 510, 445(Y2), 22, 440(H1), 441(H2) and perform the following tasks:

1. Review and update the arc flash calculations.

2. Update the current electrical model with all changes and new circuits (all equipment over 50 amps).

3. Update the arc flash labeling for new and existing electrical equipment.

4. Collect any new data for new equipment/electrical circuits and changes to the system

(all equipment over 50 amps).

5. Review and update the protection device coordination study.

6. Review and update the short circuit study.

7. Review and update the mitigation study.

8. Provide an updated final report with updated one-line diagrams.

The contractor shall provide all tools, materials, components and labor to complete an Arc Flash evaluation and apply labeling to what is known as the “north campus” 13.2kV circuit. This will include the following buildings: 10, 11, 13, 14, 16, 17, 125, 157, 174, 191-226, 230-234. These buildings were fed by a 4160V circuit during the last arc flash evaluation. It has since been changed over to 13.2kV with new underground wiring, transformers and new main switchgear.

This feeder is spliced onto the existing A3/B3 feeder.

The contractor shall provide all tools, materials, components and labor to complete an Arc Flash evaluation and apply labeling for Building 7 located on the USDA campus. This building has had an arc flash evaluation done during construction in 2009, but no reports are available for review. Contractor shall provide an updated one-line diagram of Building 7 to be included.

All existing Arc Flash Study reports will be provided to the contractor by the USDA.
