Q2. Is the contractor responsible for any guardrail installation if required?

A2. PPI does not foresee a requirement to install guardrail. Refer to the attached site location plan and guardrail drawing for additional information about existing guardrail at site location -

State Route 124 and Riverlake Way.

Q3. If yes, will both sign locations need guardrail installation?

A3. Existing guardrail to remain at site location - State Route 124 and Riverlake Way. There is no guardrail installation required at site location - I-85 Interchange at Jimmy Carter Boulevard.

Q4. Electrical/Utility Clarification: Electrical plans (Detail 3) states utility company coordination by Contractor, but the Project Manual (Section 01 12 00 Part 3 Execution) states utility company coordination by Owner. Please clarify.

A4. The Owner is only responsible for setting up the account with the utility company. The contractor is responsible for coordination as per detail 1/E2.1A and detail 1/2.1B.

Q5. Can Owner be responsible for utility power primary service to the utility meter?

A5. No. The contractor is responsible for the utility power primary service as per keynote 3 detail

1/E2.1A and keynote 3 detail 1/2.1B.
