Amendment_0001-Questions___Answers_0001.pdf

Amendment 0001 Questions & Answers 140P8326R0009 Two need attention ahead of the rest, and they are first in the enclosure.

Question 1. The Factor 3 instructions describe removing existing solar panels and constructing an off grid photovoltaic system. We cannot find photovoltaic work anywhere in the drawings or the specification.

Because Factor 3 is an evaluated factor, this affects our technical approach as much as our price.

ANSWER: TYPO- Language removed.

Question 3. Division 28 contains only the fire alarm section. There is no specification for security or intrusion detection, yet drawing T500 schedules a keypad, a motion detector and door contacts, and directs us to the specification for the keypad model.

ANSWER: A related pattern runs through the enclosure. Six sections are cross referenced by sections that are in the book but are not themselves included, and four sections are in the book but missing from the printed table of contents. Questions 13 through 17 and question 32 list all ten.

Issuing the missing sections by amendment, or confirming in writing that the scope is not required, would resolve them together.
