Since then, the Health Clinic had been locked and was never used. The intent of this project is to complete the unfinished construction work of the NAVFAC’s project and turn-over finished and operational Health Clinic facility to the local community.

The project includes the following general items of work, detailed requirements are contained elsewhere in this Statement of Work:

a. Completion of remaining construction work; mainly finishes, furnishings, patch/ paint, and replacement of interior and exterior doors.

b. Redo the existing roof gutter/ drainage for functionality.

c. Provide photo-voltaic (PV) power system for on-site electricity generation to meet the facility demand. Electrical furnishing work.

d. Re-screed the damaged walkway and re-screed the clinic roofing to provide better drainage.

e. Verify operability of the water and sanitary sewer/septic system.

f. Clear and grub vegetation in the compound.

g. Provide a 20 Liter portable hot-water boiler.

h. Provide (2) Wall-mounted split units to provide air conditioning in the delivery room and pharmacy (one unit each).
