Vision

An Architecture of Community is the long-range vision for Dover Air Force Base. This is a vision of excellence displayed in a high-quality corporate image for facilities, the landscape, and the environment. Its architecture is a language understated by post-modern and neo-classical form that remains uncluttered in a well-developed landscape setting.

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 facili-ties, landscaping, and streetscapes are presented in this Architectural Compatibility Plan (ACP). These examples depict the design standards that will ensure compatibility and achieve the vision of excellence.

2 architectural compatibility plan - Dover 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 creat-ing a unified visual environment that is based on an Architecture of Community, similar to a campus or small town. The principal design goal is to direct de vel op ment at Dover AFB toward a livable, attractive, and cohesive installation.

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 Dover 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 Dover AFB General Plan as a key component plan.

introduction 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 Dover 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 role of the Architectural Compatibility Review Board (ACRB). The implementa-

4 architectural compatibility plan - Dover 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 Dover Air Force Base as a whole. The second priority is compatibility within an ar chi tec tur al 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.

5design standards - basewide

Dover AFB has established a direction towards 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 land-scape. 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

Place buildings at grade with the entrance expressed as a feature.

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.

Use brick as the predominant wall material with stucco accents com-bined with sloped metal roofing and pronounced eaves with moderate overhangs.

Develop a strong relationship be-tween 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.

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

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

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.

Exterior surface-mounted utility conduits, lines, or equipment are not allowed (except meters and control devices).

In remote locations, paint freestand-ing pipes and above-ground utility system components dark bronze.

Communications

Collocate coaxial and telephone exte-rior components and entry points.

Align all communication components with one another on the horizontal and vertical plane.

The flightline encompasses aircraft hangars and maintenance facili-ties. Buildings should be designed with forms, materials, and color palettes similar to those of the Basewide area, but with simplified detailing more appropriate for their function. Large buildings – common to this area

– require careful design and orientation to avoid unappealing monolithic facades.

flightline / industrial architectural compatibility plan - Dover Air Force Base

BUILDINGS

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

On smaller administration facilities, use tan brick or a combination of tan brick and taupe brown stucco.

On larger facilities, use a combina-tion of tan brick and flat profile, sandstone colored metal panels.

Use a horizontal expression of sand-stone colored metal panels.

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

Cap brick parapet walls with metal or precast concrete 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 shall use gabled or single sloped parapet end walls.

Low-slope metal 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 roofing manufacturer.

Lower appendages on large facilities, small buildings, and entries may use open gabled or hipped roofs with ACRB approval.

WINDOWS AND DOORS

Use windows, clerestories, and trans-lucent fiberglass panels to promote natural lighting and reduce the mass of the facade.

Accent primary entrance doors to express their use and importance.

Secondary-use doors and frames, such as service, shall match adjacent wall surfaces.

Large hangar and overhead 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.

Reduce the density of landscaping by grouping landscape elements at 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, bollards, and de-fined roadways 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.

28 architectural compatibility plan - Dover 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.

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, chief engineer, 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 - Dover 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.
