2. Project Objectives p. 14/82

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 of medical facilities, construction of school buildings, 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 EURAFSWA has been designated as the Construction Agent for this project.

2.2 FACILITY FUNCTION

The school complex is situated in a deprived urban area very exacerbated by the poverty that prevents students from attending school if they are unable to pay the $3.50/term fee. The expansion of this school, in concurrence with the planned elimination of the attendance fee, will allow education to all young population in this area, so to influence children away from deviant behavior, and to produce more competent human resources for economic and social development of the Country.

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. 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 facility is normally open to the public.

If needs arise to work other than normal hours, obtain approval from, and coordinate with the facility owner.

~~~ End of Part 2 ~~~

3. Site Analysis p. 15/82
