1.03 SCHEDULE
A. The report shall be provided to the ENGINEER NO LATER THAN 60 days before the equipment
is shipped to the Work site. SHIPMENT AND DELIVERY OF EQUIPMENT WILL NOT BE
ACCEPTED AT THE JOBSITE UNTIL THE STUDY HAS BEEN COMPLETED, SUBMITTED
AND APPROVED BY THE ENGINEER.
1.04 SUBMITTALS
Submittals shall be in accordance with Section 01 33 00, SUBMITTALS and shall include:
A. Short Circuit and Relay Coordination Study. Time current curves shall be on 11x17 log-log type
paper. The CONTRACTOR can provide time current curves on 8 ½ x 11 log-log type paper as a
supplement but not as a replacement.
B. Arc Flash Hazard Analysis
1. Provide a copy of project specific Arc Flash labels for each panelboard, disconnect, including
all existing electrical equipment –starters, panelboards, etc.
2. Provide a color copy of project specific Arc Flash labels for each panelboard, disconnect,
motor control centers, transfer switches, including all existing electrical equipment –
panelboards, starters, etc.
3. Provide a 11x17 copy of the one-line diagram color-coded to show the incident ranges &
clothing classifications at each bus. Provide a table indicating the color coding used for each
incident range & clothing classification. The following is a recommended color coding for the
following Hazard/Risk Category numbers:
a. Green to indicate a Category 0
b. Blue to indicate a Category 1
c. Brown to indicate a Category 2
d. Yellow to indicate a Category 3
e. Orange to indicate a Category 4
f. Red to indicate Above a Category 4
C. Provide six (6) bound color copies of the completed short circuit and relay coordination study,
the arc flash analysis shall be submitted to the ENGINEER for approval. Each hard copy of
studies shall be bound in a 3-ring binder.
D. Two Software copies of actual power systems computer program project data files burned in on
a CD. The CONTRACTOR shall provide an electronic copy on a CD-ROM of all files used to
develop the electrical system model in the power system analysis program and all files for the
written study analysis and summary data tables. For instance if SKM software is used for the
power system studies, then the SKM files shall be burned in on a CD-ROM and provided to the
OWNER/ENGINEER. This shall include any library files used for circuit breakers, fuses, etc. for
the power system analysis.
