Power Waivers – Exponential Growth

2008 2009 2010

256

389

663 Reduction Strategies• 20% are dismissed

• If the TP lists an exception, and your situation meets that exception, no waiver is required.• Description is inadequate.

• 10% for issues that will always be denied• < 3” bus bar clearance, < 30” battery aisle space, mixing fused and unfused cable, etc.

• Target top 25% for IRCN / ERCN• 7% for AC outlets; 1 since IRCNs / ERCNs were published.• Primary and secondary shared cable rack (9%) and cable passing thru the rungs (5%) are in process of being updated.

Recent Power ERCNs and IRCNsAC Test Receptacles – 12’ Rule• “Every 3rd bay” rule has lost meaning with the implementation

of large spacers and skipped bay spaces.• Mobility had no specific requirement for test outlets.• Some alternate methods of providing AC outlets (under raised

floor, mounted on aux framing overhead) were causing safety concerns.

• Smaller sites with alternate outlets in walls or sites where AT&T is a tenant / guest and has no control over the location of AC outlets were not addressed with the existing language.

Section K ¶ 4.4.8 was a duplicate of section J ¶ 2.1.14.2nd IRCN was simply eliminating the redundancy.

Standard Build Program

Test & Acceptance

• AT&T Power Engineers have been receiving requests to add FPQ for “test and acceptance”.

• Power Building Blocks that install equipment requiring test and acceptance contain an included work note:– “Testing, validation, verification, and acceptance activities in

support of ATS pre-acceptance or acceptance of the work.”• Power OTVs should not add FPQ for “test and acceptance” or

any other synonymous activity. The compensation for these activities is already included in the Building Block Price Caps where appropriate.


10

Minor Material Pricing Discrepancies

• AT&T Power Engineers have been receiving requests to add FPQ for “minor material pricing discrepancies”.

• Standard procedure when a Power OTV notices a discrepancy in pricing of minor material or any component of a Building Block Price Cap is to complete a Building Block Price Cap Dispute Form and submit it to AT&T GBOS (Procurement, Supply Chain, etc.) for review.

• Power OTVs should not attempt to add FPQ to quotes for perceived discrepancies on pricing of minor material.


11

Minor Material Pricing Examples• On a recent vendor quote review the following text was

included as justification for adding Driver DC-FPQ003 in the amount of $53,326:– “Material not covered by Building Blocks. Additional cost associated

with cable, lugs, and in-line reducers”• Building Blocks for DC power cabling such as BC-CAP0xx and

their associated DC-CAP0xx and DC-CAP0xxX Drivers contain the following included work note:– Cabling of one DC power circuit or paired run, both discharge &

return, up to 10 ft. each, including terminations (i.e. flexible wire drops, lugs, inline splices, fuses, etc.).

• The requested FPQ was rejected. Do not add FPQ.


12

Labor Effort Pricing Discrepancies• AT&T Power Engineers have been receiving requests to add

FPQ for “extra labor or effort due to difficult cable runs”.• Standard procedure when a Power OTV notices a discrepancy

in pricing of installation labor or any component of a Building Block Price Cap is to complete a Building Block Price Cap Dispute Form and submit it to AT&T GBOS (Procurement, Supply Chain, etc.) for review.

• Power OTVs should not attempt to add FPQ to quotes for perceived discrepancies on pricing of labor or perceived differences in labor effort.


13

Labor Effort Pricing Examples• On a recent vendor quote review the following text was

included as justification for adding Driver DC-FPQ002 in the amount of $20,696:– “Additional labor not covered by Building Blocks due to difficulty of

cable route”• The Standard Build Program Guidelines contain the following

admonition under the section detailing use of FPQ Drivers:– There should never be any inappropriate use of a FPQ BB/DR to pay

for anything that is already included in other BBs/DRs. That includes the use of FPQ Drivers for what the OTV might generally describe as “extra effort”.

• The requested FPQ was rejected. Do not add FPQ.


14

Timing of Building Block Releases• The fluctuating cost of some commodities, especially copper,

causes pricing discrepancies in the Standard Build Program’s Building Block and Driver Price Caps from time to time.

• In order to address this AT&T has worked with several suppliers of AIW Southwire to ensure that pricing information is provided about the first week of odd numbered months to coincide with pricing adjustments effective from AIW Southwire on the 15th of odd numbered months.

• AT&T is timing Building Block releases as soon as possible after these adjustments. Are Power OTV contract managers interested in reducing the contractual 30 day announcement cycle to better accommodate these adjustments?
