PREFACE
THE DESIGN MANUAL
As part of the ongoing design and construction programs at Ronald Reagan Washington National Airport and Washington
Dulles International Airport, the Metropolitan Washington Airports Authority (the Authority), Office of Engineering, has
developed and adopted a series of documents that describe the codes, standards, details, products, and practices to be
followed by Architect/Engineers (A/Es). These documents apply to all design of construction at all facilities on property
owned by the Authority. Facilities constructed or modified on the site occupied by the National Air and Space Museum
located at Washington Dulles International Airport are exempt from the requirements of the Authority Design Manual.
The Design Manual has been developed to assist Architects/Engineers (A/Es) in understanding the practices and policies
that must be incorporated into each project. The Design Manual contains a number of specific requirements that must be
followed on all projects, as described above. These can be either Authority contracted projects, Authority direct-constructed
projects, and tenant contracted projects.
APPLICABILITY OF THE DESIGN MANUAL
The requirements for design and construction incorporated into the Design Manual and Supporting Volumes are regulations
approved by the Metropolitan Washington Airports Authority Board of Directors and shall be considered contract
requirements for all A/Es who are performing services under contract to the Authority. Although A/Es who are under contract
to tenants of the Authority may not be working under contract provisions that make compliance with these requirements
mandatory, the Authority reserves the right, as Owner of all airport facilities, and land on which tenant buildings are
constructed, to reject any design or work that does not comply with the requirements of the Design Manual and its
supporting volumes. It is, therefore, required that all A/Es performing work that will be constructed on airport property shall
perform services consistent with the Authority policies, standards, procedures, and construction requirements contained in
the Design Manual and its supporting volumes. The Design Manual should be considered equivalent to the building codes.
The Design Manual in effect at the 30% Submittal will remain the Design Manual of record up to the 100% Final Submittal.
ORGANIZATION OF THE DESIGN MANUAL
The Design Manual is made up of seven volumes.

Basic policies, procedures and standards for both Airports:
• Design Manual [THIS DOCUMENT]
Requirements for Ronald Reagan Washington National Airport:
• DCA Vol. 1 - Airport Standards and Signing Guidelines
• DCA Vol. 2 - Tenant Design Standards

January 2010
Requirements for Washington Dulles International Airport:
• IAD Vol. 1 - Airport Design Standards and Signing Guidelines
• IAD Vol. 2 - Main Terminal/Concourse Z Tenant Design Standards
• IAD Vol. 3 - Concourse B Tenant Design Standards

Requirements for All Projects:
• CADD - CADD Design Standards
The seven volumes are intended to supplement each other and must be used together, as appropriate for each airport, to
achieve the desired goals of the Authority.
An electronic version of the Design Manual and Supporting Volumes is available on CD-ROM, which may be obtained by
contacting the Authority Office of Engineering. It is also available on the Authority website at www.mwaa.com under
“Publications”.
OTHER DOCUMENTS
In addition to the Design Manual, the Authority also requires compliance for design and construction with additional policies,
procedures, and standards that are published by other departments. These documents include:
• Construction Safety Manual
• Owner Controlled Wrap-Up Insurance Program Manual
• Building Codes Manual
• Contractors Safety and Security Information (Washington Dulles International Airport)
• Safety Policy, Procedures, and Practices by the Risk Management Department
• MASTERSPEC© Specifications Sections specifically edited for Authority projects (primarily Division 01, but
including specific technical specification sections)
• Ronald Reagan Washington National Airport and Washington Dulles International Airport Survey Control Data
“To-Reach” Descriptions (two separate volumes) Note that the “To-Reach” documents for Washington Dulles
International Airport are no longer provided on the CD-ROM version of the Design Manual. These documents are
available through the Authority. The CD-ROM contains information directing the A/Es to the proper group within the
Authority to obtain this document.
• Virginia Statewide Fire Prevention Code

ACCEPTABLE STANDARDS
The standards established by the above referenced documents, together with Federal Aviation Administration (FAA),
National Fire Protection Agency (NFPA), Virginia Uniform Statewide Building Code (USBC), Construction Specifications
Institute (CSI), and other referenced materials establish the minimum level of quality and detail required of all Authority
projects. These standards in many instances may exceed those used in non-Authority design and construction projects and
are often above those established as “Code Minimums”, “Standards of the Industry”, or “generally accepted practices.”
DESIGN MANUAL REVISIONS
This edition of the Design Manual incorporates the modifications and additions that were developed during the Authority
annual review of the previous year’s Design Manual. This review includes an analysis of the existing standards and an
evaluation of the suggested revisions.
If you feel that a standard or procedure stipulated in this edition of the Design Manual should be revised, we would like to
know. To facilitate this, we have included a Design Manual Revision Form that will place your idea in the appropriate hands.
All suggestions received will be reviewed and researched and a written response will be provided.
