Andrews Air Force Base architectural compatibility plan an architecture of community

Vision

An Architecture of Community is the long-range vision for Andrews Air Force Base.

This is a vision of excellence displayed in a high-quality corporate image for facilities, the landscape, and the environment. It is expressive of the architectural character, climatic factors, and cultural influences typically associated with the area.

Architectural compatibility and Community can be achieved by understanding the vision for the base and by refining its design vocabulary. Successful examples of high quality facilities, landscaping, and streetscapes are presented in this Architec-tural Compatibility Plan (ACP). These examples depict the design standards that will ensure compatibility and achieve the vision of excellence.

2 architectural compatibility plan - Andrews Air Force Base

The Architectural Compatibility Plan (ACP) defines a clear design vo cab u lary to be used throughout the base, providing specific standards for all aspects of exterior design. Compatible architecture is ac com plished with similar buildings, using common design forms, details, materials, site features, and streetscapes.

Quality and compatibility are achieved through creating a unified visual environment that is based on an Architec-ture of Community, similar to a campus or small town.

The principal design goal is to direct de vel op ment at Andrews AFB toward a livable, attractive, and cohesive in stal la tion.

The ACP provides the design standards that will help to build compatible facilities and a quality environment.

Implementation of the standards will result in the creation of community.

introduction

Purpose

The purpose of the ACP is to define de-sign standards for buildings, site devel-opment, and streetscapes that serve to integrate the visual character throughout the base.

The ACP will help ensure consistent quality design decisions by commanders, planners, architects, engineers, mainte-nance staff, and residents. It promotes clear, concise communication between the Andrews AFB personnel and design professionals.

This plan applies to self-help initiatives, small projects, and operations and maintenance activities as well as large construction efforts.

The ACP is referenced from and supports the Andrews AFB General Plan as a key component plan.

introduction role of the Architectural Compatibility Review Board (ACRB). The implementa-tion section defines methods to facilitate the coordination and approval of design submittals.

Finally, the Appendices provide addi-tional information including an index; a list of building materials, site amenities, colors, and landscape materials; and a checklist for the ACRB and project personnel. Use the Appendices in con-junction with the general text of the ACP as a quick reference to specific materials and color specifications.

A poster is available upon request that displays photographic examples of the Andrews AFB community.

How to Use This Plan

The ACP defines three distinct archi-tectural settings: Basewide, Flightline / Industrial, and Family Housing (see the map below).

General and specific design standards for all buildings are included in the Basewide setting. Basewide standards shall be applied to all projects. When a project is located in the Flightline / Indus-trial, or Family Housing setting more specific standards from those Sections of the ACP shall be applied.

The Implementation Section of the ACP outlines key elements to ensure success in designing and constructing excellent facilities. It discusses the traditional design process, highlights the impor-tance of site analysis, and describes the

4 architectural compatibility plan - Andrews Air Force Base design stan dards

Design standards for buildings and supporting elements are outlined in this section. These standards encourage architectural compatibility using common forms, materials, colors, and architectural details.

The first priority is to achieve architectural compatibility for Andrews Air Force Base as a whole. The second priority is com pat i bil i ty within an architectural setting or sub-area. Outstanding designs for individual buildings or facilities are the third priority. The goal is to design excellent facilities that satisfy all of these priorities.

The Executive Route requires special attention in the design of landscape, paving, lighting, screening, and security.

5design standards - basewide

Andrews AFB has established a direction for architectural unity. The existing architecture depicts a predominant materials palette and a consistency of material detailing. The following design standards are applicable to the entire installation, to both host and tenant organizations.

Site planning and site development issues contribute significantly to the architectural context. Building setbacks and the scale and definition of space are as fundamental to creating architectural compatibility as consistent facade designs. Develop exterior spaces to promote pedestrian use and activity and to connect buildings and the landscape. Use the landscape with other visual elements to create greater continuity.

BUILDINGS

Achieving compatibility among buildings is essential in creating an Architecture of Community. Develop facilities with a common design theme and character to enhance architectural compatibility.

Unity is the goal, not conformity.

Style / Form

Compliment historic features on high-visibility facilities without duplicating.

Use primarily brick with precast ac-cents and sloped metal roof.

Emphasize horizontal proportions on building elements.

Rectangular elements are the stan-dard for major building masses. Use clean, simple, contemporary forms and avoid curves or angular elements in plan.

Develop a strong relationship of buildings and exterior spaces.

Articulate building facades to create areas of shade and shadow.

Scale / Massing

Reduce the monumental appearance of large structures by developing smaller massing components.

Combine functions whenever pos-sible to avoid a proliferation of small independent structures.

Break up the mass of large structures to allow for sloped roofs to the maxi-mum extent.

Existing Buildings

Match the existing materials for addition / alteration projects unless a significant change to the exterior envelope is included.

Whenever possible bring existing facilities into compliance.

WALL SYSTEMS

Walls provide the principal details and architectural features for buildings.

These contribute significantly to the character of the base. The goal is to limit the palette of materials used on base.

Consistent use of colors and materials will bind the base together and reduce visual clutter caused by too much di-versity. Use brick as the primary material with architectural precast as an accent.

Brick

Use standard-size face brick in a running bond pattern with tooled con-cave joints.

Header, rowlock, and soldier cours-ing with corbeling or other accents is encouraged.

“Carolina Chestnut” brick or blend is the standard color.

Brick may be used when appropriate for lintels, sills, arches, or quoins.

Detailing should emulate bearing wall construction.

Pebble-colored split-face block is acceptable as an accent on a limited basis and only when approved by the

ACRB.

Conceal expansion joints with down-spouts or locate them at transitions in the wall such as at pilasters or reveals.

Use buff-colored Portland cement mortar.

Efflorescence in masonry work is unacceptable. Measures must be provided to prevent it.

Architectural Precast

Precast is appropriate for lintels, sills, belt courses, and friezes.

Other facade elements made of precast should be used sparingly to ensure that brick remains the prominent material.

Light off-white is the standard color for precast concrete.

Detailed designs and patterns may be cast into the pieces to create an indi-vidual character for a single facility or complex.

Observe all horizontal and vertical safety restrictions along the flightline.

Consolidate functions where possible to eliminate smaller, individual buildings.

Integrate large masses and volumes with smaller ones to minimize the scale.

Only use pavement to buildings when necessary.

Lower the apparent height of hangars and warehouses by modulating build-ing elevations with submasses, clere-stories, openings, material changes, and architectural detailing.

Avoid large, flat facades.

All industrial facilities require curbs and bollard protection.

WALL SYSTEMS

Use brick or a combination of brick and stucco or metal panels on smaller administrative facilities.

On larger facilities use a combination of brick and flat metal panels.

Express horizontal detailing, reveals, in the metal panel system.

Do not use metal panels as the sole material for any structure.

Cap brick parapet walls with off-white precast coping.

Locate visible vents and louvers as planned design elements; avoid ran-dom placement.

Vents and louvers are to match the color of adjacent surfaces.

25design standards - flightline

ROOF SYSTEMS

All structures must use hipped or gabled roof forms.

Low-slope roofs are allowed only for very large volumes or accent sub-masses with ACRB approval.

Metal roofing for large industrial buildings may be of the minimum slope recommended by the manufacturer.

Lower appendages and entries shall have gabled or hipped roofs.

WINDOWS AND DOORS

Clerestory windows are encouraged to increase natural light and to break up the mass of the facade.

Use vertically proportioned or ribbon windows, clerestories, and trans-lucent panels to promote natural lighting to help reduce the mass of the facade.

Windows, doors, and frames must be dark bronze on brick structures.

Primary personnel entrance doors shall have full glass panels or glass sidelights.

Secondary-use doors, such as service and exit-only doors shall match adja-cent wall surfaces.

Large hangar doors must match the wall color.

LANDSCAPING

Use landscaping to soften and re-duce the scale of larger facilities.

Minimize the use of deciduous trees and shrubs to prevent leaf buildup along the apron and runway.

Limit dense plantings to entries and high-visibility areas

SCREENS AND ENCLOSURES

Integrate physical security measures into the architectural design process.

Coordinate security walls with the design of adjacent facilities or the immediate context.

Use screen walls and defined road-ways in selected locations to direct and limit facility access.

Painting of Jersey barriers is prohibited.

Residential architectural settings should express a neighborhood im-age that distinguishes them from the remainder of the base. Achiev-ing architectural compatibility relies on the use of consistent building materials, site furnishings, and landscaping. Residents are afforded some opportuni-ties to use the standards creatively to express individual pride of place in and around their homes.

family housing architectural compatibility plan - Andrews Air Force Base

GENERAL

Organize units into cohesive neigh-borhoods with defined public space along the street. Minimize the use of cul-de-sacs.

The existing housing styles should be reviewed when planning for new units.

Construct new community facilities following the basewide design standards.

27design standards - family housing

LANDSCAPING

Use mixed species and informal land-scaping to integrate new with existing housing areas and to improve the overall community.

Add plantings for shade and privacy and develop foundation plantings.

Use randomly spaced plantings and tree massing.

Landscape the perimeter edges of recreational and common areas.

Use landscaped berms to soften ma-jor arterial roads and screen undesir-able views.

Develop a street tree program.

All self-help landscape materials are to follow the ACRB's approved material list.

Avoid planting large shrubs or trees within 4-feet of the unit.

SCREENS AND ENCLOSURES

Use natural cedar shadowbox fencing for backyard privacy.

Use brown vinyl-coated chain link fencing to define yards and boundary of the housing area.

ROADS

Enhance streetscapes with landscaping, walkways, and site furnishings.

Use road features such as smaller radius corners and narrow street widths to reduce traffic speeds.

WALKWAYS AND PATHS

Emphasize pedestrian and bicycle circulation within housing areas and connect to community facilities.

Provide seating and site furnishings along walkways.

Use cast-in-place concrete patios with scoring and joint patterns.

NEIGHBORHOOD ENTRIES

Construct neighborhood entrance signs reflecting the architectural character of the setting.

Provide accent landscaping, lighting, and brick paving.

LIGHTING AND UTILITIES

Provide pedestrian-scale lighting fixtures throughout housing areas.

Provide parking lot and street lighting that matches the basewide standard for primary roads and parking lots.

28 architectural compatibility plan - Andrews Air Force Base

The ACP is a multipurpose tool that shall be used throughout the entire planning, programming, and design process, from inception to project completion for any project on base.

The ACP is implemented by the Base Civil Engineer.

While architectural designers are the primary users of the plan, it must also be used by project managers, programmers, planners, engineers, maintenance and operations personnel, self-help personnel, SABER per-sonnel and the Architectural Compatibility Review Board

(ACRB).

Any items purchased for the exterior of buildings

– including those purchased with impact cards – must conform to the requirements pre scribed in the ACP.

In the next three pages, key elements in the im ple men t-a tion process are highlighted.

implementation

29implementation

Key Elements

Adhering to key elements of the imple-mentation process leads to success in designing excellent facilities that will be compatible with and a part of the whole community.

Distribute the ACP.

Establish the Architectural Compati-bility Review Board (ACRB).

Hire good designers.

Respect the General Plan.

Process proper submittals.

Cross-reference all planning and design documents to the ACP.

Distribute the ACP

Distribution of the plan should be as wide as possible. On base, provide cop-ies to commanders of all major units and tenants, the civil engineering squadron commander, operations, branch chiefs, base architect, and community planner.

Provide copies to the major command and headquarters representatives.

Establish the ACRB

The ACRB is the installation approval au-thority for all designs and visual features on the installation.

The ACRB is organized by the Base Civil Engineer (BCE).

The chairperson as appointed.

Members include the base architect, community planner, Engineering Flight Chief, Design Chief, and others as determined by the chairperson.

The base architect, engineering disciplines, and project manager review designs regardless of ACRB involvement.

The ACRB meets as required or as a subgroup of the installation Facilities Board (FB).

Most projects, regardless of size, must be approved by the ACRB. (The chairperson makes the determination on review requirements).

Design projects are submitted to the ACRB by the base-assigned project manager (see project checklist on page A5 for submittal requirements).

ACRB Project Checklist

All projects and service contracts shall be reviewed by the ACRB using the checklist on page A5. The Base project manager is responsible for providing the design checklist to the ACRB for completion.

30 architectural compatibility plan - Andrews Air Force Base

Hire Good Designers

Ensure the involvement of design oriented personnel in the A-E selection process.

Select A-E firms that are sensitive to and understand architectural compatibility.

The AF project manager provides cop-ies of the ACP to the designer before design begins.

Respect the General Plan

All new projects must agree with the goals and objectives outlined in the in-stallation master plan to ensure that the siting of new projects is compatible with adjacent facilities.

Process Proper Submittals

All design projects are reviewed by the ACRB. This includes Requirements Documents, Concept Design, and Final Design submittals.

Submittals shall include the required information and data at the appropri-ate times, and the process shall allow adequate review time.

Requirements Document

In the initial submittal, the A-E defines

– with the help of the AF – the require-ments for the project. It may explore potential solutions, but more importantly, it includes bubble diagrams depicting the relationships of major functional elements and site / facility development options. This submittal is reviewed by the ACRB.

Each submitted package will comprise the following.

Scope / Programming Requirements

Project Description

Goals and Objectives

Sub-area Development Plans

Site Inventory / Site Analysis

Spatial Relationship Analysis (i.e., relationship to site)

Adjacent Facilities and Project Site Photos

Site Inventory / Site Analysis includes (but is not limited to): vehicular traffic patterns, view, climatic conditions, envi-ronmental, safety, utility constraints, and geographic conditions. Refer to sketch.

31implementation

Develop site plans, floor plans, roof plans, and building elevations concur-rently to ensure the proposed solution is a comprehensive design. Floor plans must be developed with consideration of the site and building massing.

The ACRB will review concept submit-tals. If the initial submittal is rejected, or if there are significant concerns or com-ments, a resubmission is required prior to proceeding to the next design stage.

Each submittal package shall include:

Concise Verbalized Design Concept

Systems Description

Adjacent Facilities and Site Photos

Site Plans (colored)

Floor Plans

Composite Elevations (with color and shadows)

Mechanical / Electrical Communica-tions Entrances and Equipment Locations and Configurations.

Building Sections

Roof Plan

Massing or Perspective Sketches

Study Model (as required)

Cost Estimate

Final Design

The final design shall remain consistent with the approved concept design. It includes highly developed drawings that further refine and detail the visual and functional quality of the design.

As a minimum, each submittal package shall include the following:

Formal Colored Rendering (early in this phase)

Material / Color Boards (interior and exterior)

Catalog Cuts (photos)

Design Analysis

Cost Estimate

Contract Documents

Contract Documents (CDs)

Contract documents must be in Auto- CAD and include comprehensive draw-ings and specifications to meet all of the standards defined by the ACP.

All civil, mechanical, and electrical drawings must be consistent with the ar-chitectural drawings. All utility elements such as light fixtures, transformers, panels, grilles, vents, piping, etc., must be shown on the architectural drawings.

Concept Design

This submittal must include adequate information to fully describe the project design, allowing customers / clients to easily comprehend the proposed solu-tion. The goal is to achieve AF customer understanding and approval early in this process.

Multiple submittals may be required for large or complex projects. Generally, completion of concept design requires two submittals. The initial submittal pro-vides a conceptual approach to the solu-tion, while the final submittal presents a refined and more detailed design. These submittals shall be design presentation documents rather than construction documents.
