2. Project Objectives p. 15/95

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 existing Literacy Center promotes public health education programs. The renovation and expansion of its facilities will offer more opportunities to uneducated teenage mothers and other educationally disadvantaged adults and young people in the community to get access to information and materials like basic reading, computation, public health, family planning methods, public health awareness, and vocational training.

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.

~~~ End of Part 2 ~~~

4. Building Requirements p. 16/95

3 SITE ANALYSIS

3.1 EXISTING SITE CONDITIONS

The current facility is approximately 25 years old and in a general state of disrepair.

The foundation and walls are constructed of concrete, with a wood truss roofing system covered by galvanized metal roofing material. The interior partitions are wood frame walls.

The roof structure is heavily damaged. The concrete portions of the structure are generally in good repair, excepting for needing minor patching in some areas and new paint overall.

There are four separate concrete staircases leading into the structure. The ground around the two staircases in the front of the building has eroded away leaving a large step-up to get onto the stairs.

The bathroom with a sink and toilet drains into a small septic system in the rear of the building.

The electrical system is in poor condition, the electrical box and wiring was damaged and jury-rigged.

The building is connected to the public electrical, water, and telephone systems.

3.2 CURRENT SITE LAYOUT

The site layout allows for building expansion to the rear of the existing structure.

Expansion to the right to the front side is limited due to proximity of property lines.

The space on left side is intended for parking area.

FACILITY FOOTPRINT

A scaled drawing with exact dimensions showing the site lay-out including location and dimensions of all existing buildings, latrines, obstacles, and perimeter wall (if any) with gate locations shall be included in the concept design.

4. Building Requirements p. 17/95

3.3 PHOTO DESCRIPTION

The facilities currently consist of a 24m x 11m building located at Derriere La Prison in Libreville.

Photos 1 and 2 shows the building front and rear façades as they currently appear.

Photos 3 and 4 show the interior finishes and partitions.

Photo 5 shows the current restroom with non-operational faucet and flushable water closet; fixtures are connected to an unusable sewage system and septic tank

3.4 SITE DEVELOPMENT REQUIREMENTS

An example of the final school layout is roughly sketched below.

Final new facility layout and orientation shall be selected to best fit the topography in order to minimize the required grading work.

It shall be coordinated with the PM and the school officials after the footprint of current layout has been submitted.

DESIGN CONSTRAINTS

Design of the facility and its location and orientation within the proposed site shall take into consideration all natural and man-made constraints, which include but aren’t limited to:

Topography: all site slopes shall be taken in account in order to minimize the need for cut and fill operations Vegetation / Landscaping: vegetation shall be protected, and landscaping design shall be maintainable Climatology (solar orientation, etc.): Design shall take advantage of prevailing wind direction and solar orientation to naturally moderate the interior temperature of the buildings Geotechnical Data: Foundations and structural components of the buildings shall be designed in accordance with geotechnical soils report information. Geotechnical engineering services shall be provided if no current report exists for the site. Design shall be in accordance to the seismic zone of classification of the project site.

Hydrographic Survey: a hydrographic survey shall be performed to determine the storm water runoff Vehicular Access and Circulation: existing vehicular access shall be taken in account

4. Building Requirements p. 19/95

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.

ACCESS, CIRCULATION, AND SITE DEVELOPMENT

Any proposed vehicular and/or pedestrian access, paths, sidewalks, steps, parking areas, outdoor recreation area, landscaping etc. shall be reported on the site plan, as well as areas of material storage and temporary security fencing.

All proposed drainage channels shall be shown on the site plan.

The location of the construction sign and any other signage required by local authorities shall be indicated on the site plan.
