- Please see the drawings.

8. Can you provide reference photos of existing site conditions?

- Please see the photos.

9. Are there any known obstructions or congested utilities along the route that could affect cable-pulling operations?

- No

SBU - CONTRACTING AND ACQUISITIONS

- Contractor’s qualified Electrical Engineers can perform the testing procedures and methods in accordance with NETA-ATS (InterNational Electrical Testing Association – Acceptance Testing Specifications).

12. Is certified personnel required to conduct confined space activities?

- Safety will be governed by the following mandatory measures:

a. Submission and Approval of Safety Plan: The contractor must submit a comprehensive job-specific safety plan, which we will review and approve prior to work commencement.

b. Strict Adherence to APOSHO Permit System: A confined space work permit from our APOSHO system is required. This permit will only be issued after we have verified the contractor has all required safety equipment (e.g., gas monitors, retrieval gears, ventilation equipment, barriers, signages, PPE’s, etc.)

and procedures in place. Similar to a standard project requirement that contractors are familiar with.

c. Mandatory Safety Briefing: The requirements of the permit and the approved safety plan will be a key focus of the pre-task safety briefing to ensure all personnel are fully aware of the hazards and controls.

13. Will phased installation be required to maintain at least one operational pump station during construction?

- No. Pump stations 1 and 2 are temporarily powered up from another power feeder and supply source.

14. Will the Embassy assist with customs clearance of imported materials, beyond issuing a tax exemption certificate?

- To be responded by C&P.
