Amendment 003

The purpose of this amendment is to revise the specification and bid schedule, revise and add drawings, and answer additional contractor questions.

A. Replace the specification with the attached revised specification, Spec No. 936 REV. 02, in its entirety. All specification changes are annotated with a line in the right sidebar of the document. Changes to include but are not limited to the PCB concentration of the oil in the existing transformer. Also addressed are the placement, installation, conductor size, conductor routing, fueling and operation of the temporary generator.

B. Remove and replace original drawing package with attached drawing package named Spec No. 936 Rev. 01 in its entirety. Below are the specific changes to the drawing package:

a. Drawing ATL0218-A02 Rev. 1 of the original drawing package is replaced in its entirety with drawing ATL0218-A02 Rev 2. The revised drawing appears the same, but the measurements have been changed.

b. The below drawings have been inserted into the drawing package:

i. FOL T1-1000 Rev L (pg. 7).

ii. FOL T1-1500 Rev. G (pg. 15)

C. The bid schedule addresses minor grammatical changes and revises CLIN 13 to now read “Installing 12/c No. 10AWG control cable”

D. Below are answers to additional contractors questions:

Question 1. Can WAPA provide the PCB oil concentration % for the existing transformer that is to drained and removed from site?

Answer 1. Please see below:

Question 2. The new spec with nameplate has changed the unit being quoted significantly, as IEEE standards were used for all items not specified in the current quote. The spec changes that are driving a redesign are as follows:

· Current transformer nameplate has DETC in the tertiary winding

89503118BWA000009

Amendment 003

· Current transformer shows 4.7% impedance as opposed to IEEE standard of 10%

The revised specification does not call out either of these requirements.

Is the new system required to work in parallel with another system, requiring an exact copy of the existing unit?

Also, are losses being considered in the evaluation?

Answer 2. The KV4A Transformer is provided by WAPA; therefore, these considerations have been taken into account. The contractor for this requirement is only connecting to the government furnished transformer after the transformer manufacturer contractor has set it on the pad.

E. The bid opening date remains unchanged. The bid opening remains August 23, 2018 at 2:00 PM MST (Arizona local time).
