Transformer Replacement

SCOPE OF INVESTIGATION:
I was tasked with determining what the cost would be to reconnect utility power to the new 2000
amp, 240 volt three-phase service had the owner elected to replace the damaged service.
My investigation consisted of the following tasks:
a. I visited the site on May 2, 2019, and was met by with the building owner Craig Hanriot, I
went onto the roof, looked down into the fenced and secured utility yard that protects the
high voltage (HV) (12,000 volts) wiring and transformer(s) from public access. I took
pictures (Exhibit A) of this area, by the outline stains it was evident that four transformers
had previously been installed on the concrete pad.
b. While onsite I took pictures (Exhibits B & C) through the fenced gate of the single-phase
transformer, HV cable, HV parking stand, and the HV wire going into underground conduit.
c. While onsite I took pictures inside the building of the 400 amp, 120/240 volt, single phase,
service, and three distribution panels for future reference, even though these items are not
currently in question. No exhibit was created.
d. I read the Clients Statement of Claimed Damages.
e. I read the Amended Terms of Reference.
f. I read the BWP produced documents stamped BURBANK000001 through
BURBANK000147.
g. I read the deposition transcript of Riad Sleiman (BWP Responsible Electrical Engineer)
dated May 2, 2019 and examined the deposition’s exhibits 01 through 08.
h. I read the Claimants’ Responses to RESPONDENTS’ SPECIAL INTERROGATORIES,
SET TWO.

Conclusions and Opinions:
Exhibit D:
Property Owner, Craig Hanriot on Dec 3, 2015 confirms in an email to Scott Anderson
(BWP) that “The various engineers that are working on this project have told me that the
service that has been used at the property is 2000 amps 240 volts 3-phase, 3-wires and the
second is 400amps 120 / 240v. 1-phase, 3-wires. After speaking with all of the people that
needed to decide on this it was agreed that the service and transformers that have been
used in the past will be adequate for the future needs of the operation.”
This statement by Mr. Hanriot confirms to BWP that the three existing transformers
are large enough for future needs.
Opinion 1: There is no need to change the three existing transformers should the
new 2000 amp 240 volt, three phase, service be installed.
Exhibit E: first conclusion
BWP Electrical Engineer, Scott Anderson on November 13, 2018 responds in an email to
Damion Robinson’s questions that “the existing (3) 75 KVA customer station transformers
could handle the new tenants load.”
Opinion 2: BWP Electrical Engineer states the (3) 75 KVA customer station
transformers could handle the new tenants load. Replacement of the three
transformers that would serve the new 2000 amp 240 volt, three phase, service is not
required.
Note: Three existing single transformers (TUBS) together are electrically equivalent
to a 225 KVA pad mount (single enclosure) transformer.
Exhibit E: second conclusion
BWP Electrical Engineer, Scott Anderson on November 13, 2018 responds in an email to
Damion Robinson’s questions that replacing the 2000 amp service with a load schedule
that showed that the existing (3) 75 kVA customer station transformers could handle the
new tenants load would have been for the bussing to be inspected and or replaced by the
customer and the cables from the transformers to the bussing replaced by BWP and new
metering installed. Engineering, line crew and electrical equipment support costs would be
included in this scenario.
Opinion 3: No Primary high voltage cable or conduit would have to be replaced. This
minimizes the cost from BWP to reconnect the EXISTING transformers to the new
2000 amp 240 volt, three phase, service.
Exhibit E: third conclusion
BWP Electrical Engineer, Scott Anderson on November 13, 2018 responds in an email to
Damion Robinson’s questions that no load schedule provided or of a load schedule
provided that required the customer station transformers to be upgraded would have been
for the bussing to be inspected and or replaced by the customer and the cables from the
transformers to the bussing replaced by BWP, the (3) existing transformers removed and
replaced by BWP and new metering installed. Engineering, line crew and electrical
equipment support costs would be included in this scenario.

Exhibit F: first conclusion
BWP Document RULES AND REGULATIONS GOVERNING ELECTRIC SERVICE, item
2.01 (j) States that these Rules and Regulations are “guidelines” and that “Below 750KW
Load, BWP requires on-site transformation for all new three-phase services above 200A”.
Opinion 5: The Rules and Regulations do not state Pad Mount transformers are
required but that on-site transformation is required.
Opinion 6: Pole mounted transformers with the secondary wires run down the pole
or overhead secondary services are not allowed to be installed for three phase
services in excess of 200 amps.
Opinion 7: On-site transformation can be achieved with three TUBS or three separate
transformers that could be mounted on a pole, but could instead be mounted on a
concrete pad (like the original installation, see exhibit B) or a rectangular -all in oneenclosed pad mounted transformer could be used, either type of transformer
arrangement is allowed by BWP.

Exhibit F: second conclusion
BWP Document RULES AND REGULATIONS GOVERNING ELECTRIC SERVICE, item
2.01 (j) States “750 KW – 3 MW Any service above 750 KW requires a pad mount switch.
BWP requires two pad mount transformers.”
Opinion 8: The proposed 2000 amp rated service with the maximum allowed loading
of 80 % has a full load capacity of 1600 amps, at 240 volts, three phase, is rated at
665 KVA. The load of 665 KVA can be supplied by three 225 KVA TUBS.
Opinion 9: 665 KVA is less than 750 KVA, hence the BWP requirements of this
paragraph do not apply to a new 2000 amp service.

Exhibit G:
BWP Electrical Engineer, Scott Anderson confirms in an email to his supervisor Riad
Sleiman, that WAM # 1702838-01-04 (400 amp service single phase service) is complete
regarding the disconnect and reconnect of power and customer station work at 3401
Pacific. WAM Tasks
01, 02, 03, &. 04 have been set to “finished”.
The (Actual AIC) charges are as follows:
Details
Engineering $ 667.77
L &E Labor $ 5,966.57
Materials $ 457.60
Metering $ 530.00
Test Shop Labor $ 545.82
Equipment $ 129.12
Total $ 8,296.88

Exhibit H
BWP Electrical Crew group email discussing the existing high voltage (HV) cable, neutrals,
parking stands and future growth.
“I have a feeling that the new owner might request a 3-phase service sometime in the
future. Is there any way to keep what’s there and facilitate the addition of a three-phase
service in the future? can leave the three ways completely intact for future growth. as long
as Electric shop leaves the parking stands as is everything is fine,
All of the neutrals are tied together. When they are ready I’ll just energize A-Phase”

Opinion 11: The building owner, Craig Hanriot had already notified BWP that he had
decided NOT to install the new 2000 amp 240 volt, three phase, service. The email
demonstrates that the Electrical Crew Group that contributed to this email were in
agreement that the existing HV facilities could be left in place for a future three phase
service.

Opinion 12: There was no requirement to remove the electrical distribution
infrastructure at the time of connecting the 400 amp single phase service. The
electrical distribution infrastructure could be left completely intact, at no additional
cost to the utility or the customer. This is an indication that the TUB type
transformers mounted on the existing pad would still be acceptable to BWP in the
foreseeable future for three phase services.
Exhibit I
BWP production document “Nasmyth Burbank Contract Reconciliation Document”.
Opinion 13: This construction document made the owner aware that by not installing
the new 2000 amp 240 volt, three phase, service that $28,080,00 would be given as a
credit by the construction contractor.
There would be additional savings to the owner by the way of BWP AIC costs
generously estimated in Opinion 10 above, of $24,890.64. The total saving would be
approximately $52,970.64 to the owner by not installing the new 2000 amp, 240 volt,
three phase, service.

Exhibit J
Claimants’ Statement of Claimed Damages.
Page two, line 20, shows the cost to “Replace exterior transformers, engineering,
and installation” is estimated at $391,250.00. Page three has the breakdown of these
costs including overhead and profit by the contractor.

Exhibit K
Claimants Responses to Respondents’ Special Interrogatories, Set Two.
Opinion 15:
Alternate 1 to opinion 14: A TUB type transformer was allowed and is what was
originally installed at this location. This opinion is supported by my previous
opinions 5, 6, 7, 8, & 9.
Assuming new transformers were installed, sized for the 2000 amp (which has a
maximum allowable load 1600 amps), 240 volt, three phase, new service, this would
require three 225 KVA TUB type transformers. The total installed cost is estimated to
be $61,658.64 for the TUB transformers and BWP AIC costs.
Alternate 2 to opinion 14: No pad mount transformer is required by the BWP Rules
and Regulations for this installation, only on-site transformation is required. The
claimant has made an error in believing that BWPs regulations would require a new
pad mount transformer due to “no load schedule being provided to BPW” for the
new 2000 amp, 240 volt, three phase, service. Assuming an all in one, pad mount
transformer was selected the total installed cost is estimated to be $77,073.30 an
increase of about 25%.
