EXISTING CONDITIONS

Work under this contract will include buildings 624, 626, 640, 655, 695, 696, 697, 698, and 699 across Housing Groups C, D, and G. Refer to Section 1.1: General scope of Work, for an overview of existing conditions.

The Ikego Housing Area first opened in 1996. These buildings consist primarily of concrete construction. Interior walls vary from being solely of reinforced concrete with painted finish, to walls that have been furred out with light gauge metal stud framing and gypsum board finish. Typically, walls that support stairways are painted concrete, while all other interior walls include framing and either a gypsum board or ceramic wall tile finish.

Refer to Attachment 01 11 00-B Concept Drawings for existing building dimensions and additional detail. Photographs of existing conditions have been provided in Attachment 01 11 00-C Photographs. These photographs include buildings from the Ikego housing area that convey the general nature

of conditions and spaces to be encountered. Photos are not all encompassing and shall be used for reference purposes only.

DESIGN CONSIDERATION

The Designer of Record (DOR) shall provide a project design with exterior elevations that are architecturally compatible with the Yokosuka/Ikego Master Plan and match the color, materials, and look of adjacent family housing buildings.

The elevations provided in Attachment 01 11 00-B Concept Drawings shall be considered the minimum in terms of exterior architectural elements required for this project. Further development of all the building elevations is necessary and may require incorporation of additional architectural elements to fully achieve the above stated objectives. The Designer of Record shall coordinate the necessity of adding such elements with the Contractor during the proposal stage.

Interior design for the project shall emphasize durable materials and furnishings that can be easily maintained and replaced. Sustainable interior finish materials shall be selected to achieve a balance between occupant convenience and satisfaction, sustainability, appearance, durability, maintenance cost, and life cycle cost.
