The facility, as described herein consists ofone Dormitory consisting of three buildings to house a total of 144 personnel to be located at Ellsworth Air Force Base, SD. The facility shall conform to the requirements of UFC 1-200-01 General Building Requirements and DORMS-4-AIRMEN design standard. In the event of a conflict, Designer of Record shall comply with requirements in this Contract (including bridging documents), the DORMS-4-AIRMEN standard, and UFC requirements - in that order of precedence. If a conflict between other reference documents or criteria occurs, the more stringent requirement shall govern.

Drawings have been provided in the appendices as bridging documents. The floor plans for this project are to be the basis of design for the intended floor plan layout as required under this RFP.

SECTION 01 82 00 Page 8

The overall building design and configuration has been developed by the Government and approved by the users. It was determined by the Government that this was the best solution to meet the users' needs for the design development of this project. However, other design solutions which slightly modify the furnished solution may be acceptable, and will be reviewed on their design merits against the furnished criteria, subject to Government approval.

Design alterations will only be allowed as required for the following:

a. Code compliance.

b. Material modular sizing considerations.

c. Economy of detail connections.

d. Access to/for building systems and utilities.

e. Accommodation of required structural, mechanical, plumbing, fire protection, electrical, and communication systems.

f. Handicap accessibility provisions.

The architectural drawings, specifications, design analysis and calculations to accurately show the extent of work, are to be provided as required for this proposal, for the charrette, 60 percent design, and the Final design submittals, and shall be in accordance Sections 01 33 00.32

DESIGN AND CONSTRUCTION DELIVERABLES/PROCEDURES 01 33 00.36 - 60 PERCENT

DESIGN REQUIREMENTS, and 01 33 00.38 - 100 PERCENT DESIGN REQUIREMENTS.

1.3.2 Facility Design

Approximate 35% design architectural drawings have been included in the appendices of this Contract as bridging documents. The Dormitory facility shall be designed to accommodate 144 bedrooms total and meet LEED Silver (v2009) certification requirements. Each building will be substantially identical and shall have two dorm modules (8 beds) on the first floor followed by four modules (32 beds) on the second and third floors, followed by two modules (8 beds) on the fourth floor. The facility shall conform to the requirements below and as listed in this Contract.

Other accessible Dormitories are available elsewhere on Ellsworth AFB, so the dorm modules in this facility need not be fully-accessible. All public spaces, corrdiors and features outside of the dorm units shall be fully accessible. Requirements for vertical connection of accessible routes need not be met.

SECTION 01 82 00 Page 9

Elevator capacity shall not be less than 2,500 lb and shall be of a plan size/dimension sufficient to accomodate a standard dormitory bed as identified in the plans. Elevator shall be "holed" or "hole-less" hydraulic type of configuration adquate for the height and configuration of the proposed dormitory buildings.

1.3.5 Antiterrorism/Force Protection

This building shall include design provisions meeting the requirements of UFC 4-010-01, DOD Minimum Antiterrorism Standards for Buildings. This includes, but is not limited to, minimum setbacks from parking areas and vehicle access drives, glazing and blast resistance requirements, progressive-collapse, visual screening, HVAC intake louvers location requirements, and other protective features as outlined in the UFC.

1.3.6 Desired Exterior Image and Architectural Compatibility

This project represents the first phase of a new dormitory master plan at Ellsworth AFB. While this project will be the first-constructed application of that master plan, Ellsworth AFB has studied the desired aesthetic. The bridging documents in the appendices identify some of the essential aesthetic components that shall be into this project. Also note that Ellsworth AFB has many buildings that reference a "Prairie-Style" set of aesthetic queues. The buildings in this Project shall emphasize horizontal lines, large roof overhangs, and emply other "Prairie-School" techniques to create visual continuity between the buildings in this Project and existing "Prairie-Style" buildings on base. Required materials have been selected for the project to achieve the shared values of low operating and maintenance costs, energy efficiency, durability, and compatibility with other new construction on Base. Any materials not specifically identified shall also be selected with those shared values in mind.
