2 PROJECT OBJECTIVES

2.1 MISSION STATEMENT

DoD humanitarian assistance activities were first authorized by US Congress in 1986. In FY 1996,

DoD was permitted to fund a wider variety of HA activities, including using contracts and deployment

of U.S. Government personnel to conduct specific humanitarian projects.

Typical projects include the refurbishment or the new construction of medical and school facilities,

digging of wells, improvement of sanitary facilities, and training of host country personnel in

internally displaced persons/refugee repatriation operations and in disaster relief and emergency

response planning.

The DoD, in an attempt to assist in development and implementation of the Humanitarian Assistance

Program, is funding and coordinating the project which is the subject matter of this contract.

NAVFAC EAC has been designated as the Construction Agent for this project.

2.2 FACILITY FUNCTION

Building this storage facility will complement the development of a mobile hospital and maintenance

facility currently being constructed at the CAMME compound. The increased and improved storage

capacity will allow the Djiboutian MoH to absorb medical donations and manage a suitable medical

inventory that will allow the government to properly respond to emergencies.

This project will assist the Djiboutian MoH in meeting United Nations Sustainable Development and

achieving the Universal Health Coverage through better stocking at outlying clinics.

2.3 PROJECT SPECIFIC PRIORITIES

Sustainable Design - Integrate sustainable principles into the design, development and construction

of the project. Reduce the total cost of ownership of the facility using a whole building, life-cycle

approach. Provide integrated sustainable design strategies and features to minimize the energy

consumption of the facilities; conserve resources; minimize adverse effects to the environment; and

improve occupant productivity, health, and comfort.

Energy Conservation - Integrate energy conservation principles into the design, development and

construction of the project. Reduce the total cost and consumption of energy in the facility using a

whole building approach.

2.4 APPROPRIATE DESIGN

The design is to maintain an indigenous character. The facility’s style and finishes shall resemble

those of surrounding newest buildings in the vicinity.

As much as possible, materials are to be available locally to promote the local economy and to take

advantage of the skills and experience of local trades-persons. Construction methods are to be in-

line with those used locally to take advantage of the skills and experience of local trades-persons.

2.5 WORKFLOW PROCESS - HOURS OF OPERATION

The work of this contract is to be done during the hours the compound facilities are normally open to

the public. The effect of noise and dust from site work shall be minimized by performing site work

during hours of the day and/or days of the week when the facilities are less frequented.

If needs arise to work other than normal hours, the schedule shall be coordinated with the facility

manager, and approved by PM or COR.

3 SITE ANALYSIS

3.1 EXISTING SITE CONDITIONS

The area intended for the construction is included in a fenced area situated within the CAMME

(Medicament and Essential Material Purchase Center) compound in the PK12 Balbala area.

The site is easily accessible from 2 gates from 2 different paved roads in decent conditions; it’s

reachable in 20‘ drive from Djibouti City center; the area intended for the construction is on the

southern side, it’s lightly sloped and empty.

The compound is served by electrical supply while the water needs to be trucked into water tank; no

sewage service available. (GPS coordinates: 11.545594, 43.079112)

The satellite view is reported below. The area pointed by the blue arrow indicates the location for the

new facilities. The exact construction footprint and building orientation shall be agreed with the

beneficiary and the PM / COR. A scaled drawing with exact dimensions showing the current project

site lay-out (with position and dimensions of surrounding existing buildings, obstacles, access roads,

walkways, and perimeter fence) shall be included in the concept design.

A wider satellite view showing

where the project site is located

is reported on the side.

runoff.

Vehicular Access and Circulation: existing vehicular access shall be taken in account

Site Utilities: location and capacity of all existing utilities on site shall be verified prior to start design

Site Drainage: the facilities shall be designed without negative impact from storm water runoff to the

adjacent area of the site.

Existing Buildings: Identify and accurately locate on the site plan all existing buildings on the site.

Fencing: Identify and accurately locate on the site plan all existing fencing on the site.

Permits: all permits, approvals, and authorizations needed to implement the design shall be

obtained prior to start construction.

WORKSITE ACCESS, CIRCULATION, AND LAYOUT

A temporary site plan shall be submitted to indicate the temporary security fencing as well as any

proposed vehicular and/or pedestrian access, paths, sidewalks, steps, parking areas, material

encountered and galvanic corrosion may occur between adjacent underground metallic masses and

the copper-clad rods.

In high resistivity soils, 3 m sectional rods may be used to obtain the required resistance to ground;

however where rock is encountered, additional rods, a counterpoise, or ground grid may be

necessary.
