Vision

An Architecture of Community is the long-range vision for Joint Base Charleston.

This is a vision of excellence displayed in a high-quality corporate image for facilities, the landscape, and the environment. It is founded on an understanding and respect for the local architectural character and creating compatible, responsive designs.

Architectural compatibility and Community can be achieved by understanding the vision for Joint Base Charleston and by implementing a design vocabulary. Success-ful examples of high quality facilities, landscaping, and streetscapes that exist at the base and at other military installations are presented in this Architectural Compatibility Plan (ACP). These examples depict the new design standards that will bring about compatibility and achieve the vision of excellence.

The Architectural Compatibility Plan (ACP) defines a clear design vocabulary to be used throughout JBC, providing specific standards to be observed in all aspects of exterior design. Compatible architecture is accomplished with buildings that are similar, but also through the use of common design forms, details, materials, site features, and streetscapes.

Quality and compatibility are achieved through creating a unified visual envi-ronment that is based on an Architecture of Community, similar to a campus or small town. The principal design goal is to direct development at Joint Base Charleston toward a livable, attractive, and cohesive installation.

The ACP provides the design standards that will help to build compatible fa-cilities 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 design standards for buildings, site development, and streetscapes that serve to integrate the visual character throughout the base.

The ACP will help ensure consistent quality design decisions by commanders, plan-ners, architects, engineers, maintenance staff, and residents. It promotes clear, concise communication between Joint Base Charleston as the client and design professionals.

This plan applies to self-help initiatives, small projects, and operations and mainte-nance activities as well as large construc-tion efforts.

The ACP is referenced from and supports the Joint Base Charleston Master Plan and Supplements.

tation section defines methods to facilitate the coordination and approval of design submittals.

Finally, the Appendices provide additional information including an index; a list of building materials, site amenities, paint col-ors, and landscape materials; and check-lists for the ACRB and project personnel.

Follow the established standards found in this section except on building additions or alteration projects where existing mate-rial palettes should be preserved. Use the Appendices in conjunction with the general text of the ACP as a quick reference to spe-cific materials and color specifications.

How to Use This Plan

The ACP defines general and specific de-sign standards for any site and all buildings.

The ACP is then broken up into the main two geographic areas of Joint Base Charles-ton--the Air Base and the Weapons Station.

Each of the geographic areas has specific guidelines in order to more closely tie them together creating a unified campus setting.

However, each area has sub-regions with specific guidelines relating to function or existing conditions.

The Implementation section of the ACP out-lines key elements to ensure success in de-signing and constructing excellent facilities.

It discusses the traditional design process, highlights the importance of site analysis, and describes the role of the Architectural Compatibility Review Board (ACRB), or the designated review authority. The implemen-introduction 3

What is Joint Base Charleston?

Joint Base Charleston is a United States military facility located in the South Carolina cities of North Charleston, Hanahan and Goose Creek. The facility is under the jurisdiction of the United States Air Force 628th Air Base Wing, Air Mobility Command. The facility is an amalgamation of the United States Air Force Charleston Air Force Base and the United States Navy Naval Support Activity Charleston which were merged on 1 October 2010.

Joint Base Charleston was established in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of facilities which were adjoining, but separate military installations, into a single joint base – one of 12 joint bases formed in the United States as a result of the law. The Joint Base Charleston area encompasses more than 20,000 active-duty, reserve and civilian personnel, spanning across its Air Base and Weapons Station.

Joint Base Charleston design standards

Design standards for site, buildings and supporting elements are outlined in this section. These standards encourage architectural compatibility through the use of common forms, materials, colors, and architectural details. These are meant to provide guiding principles for all new construction.

The first priority is to achieve architectural compatibility for Joint Base Charleston as a whole. The second priority is compatibility 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.

Additional standards are broken up into the two main areas of JBC: The Air Base and Weapons Station. These areas are further defined into districts and overlay zones. After reviewing the general standards, see the appropriate section for more specific requirements.

All site and building designs shall meet the most current UFC/DOD Anti Terrorism- Force Protection Criteria.

JBC design standards- site 5 roads

JBC design standards -commerical 15

The following design standards are applicable to the entire installation, to both host and tenant organizations. They are based on the existing archi-tecture and encourage contemporary adaptations of the vernacular.

Site planning and site development issues contribute significantly to the architectural con-text. Building setbacks and the scale and definition of space are as fundamental to creat-ing architectural compatibility as consistent facade designs. Features such as esplanades, allees, promenades, parkways, plazas, and courtyards create an organizing bond between buildings and the landscape.

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

– as opposed to conformity – is the goal.

Style / Form n Buildings should be elevated above the ground plane with the stair, ramp, and other transition elements expressed as an architectural feature.

n Develop a hierarchy of individual facade components that are expressed visually.

n Emphasize vertical proportions on fa-cades through the use of columns and pilasters.

n Articulate building facades to promote areas of shadows.

Scale n Reduce the monumental appearance of large structures by developing smaller massing components along the ground plane.

n Articulate large roofs with clerestories, monitors, and skylights.

n Recall a human scale in brick facades with water tables, belt courses, sills, lin-tels, friezes, and copings in a contrast-ing material, color, or pattern.

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

n Use openings, changes in material, and architectural detailing to articulate large monolithic walls.

wall sysTeMs n Use brick on all one- and two-story buildings in high-visibility areas.

n Cap brick parapet walls with precast buff-colored concrete coping.

n On larger structures, use flush metal panels above the first level of brick.

n Use metal panels on support facilities in less prominent locations.

n Provide curbs and bollard protection to control vehicular / equipment traffic where necessary.

n Locate visible vents and louvers as planned design elements; avoid random placement.

n Vents and louvers are to match the color of adjacent wall panels on painted structures and should be dark bronze on brick structures.

JBC design standards - industrial 25 n All structures must use hipped or gabled roof forms.

n Brick structures may use sloped para-pet end walls with horizontal flanks.

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

n Use built-up roofing material where minimal-slope roofs are permitted.

n Screen low-slope roofs with parapet walls.

windows and doors n Use vertically proportioned or ribbon windows, clerestories, and Kal-wall to promote natural lighting and reduce the mass of the facade.

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

n Primary entrance doors are to have full glass panels.

n Secondary-use doors, such as service and exit-only doors, shall be painted to match adjacent wall surfaces on painted structures.

landscaping n Reduce the density of landscaping by grouping landscape elements at public areas, such as entries or courtyards.

screens and enclosures n Integrate physical security measures into the architectural design process.

n Use screen walls, raised planters, and defined roadways in selected locations to direct and limit facility access and increase force protection.

n Painting of Jersey barriers is prohibited.

Residential architectural settings should express a neighborhood image that distinguishes them from the remainder of the base. Achieving archi-tectural compatibility relies on the use of consistent building materials, site furnishings, and landscaping.

Residents are encouraged to use the standards creatively to express individual pride of place in and around their homes.

screens and enclosures n Use wood fencing for backyard privacy.

Wood is allowed only in the Residential setting.

n Incorporate wood shadow box inserts in fencing and trash enclosures.

n Use vinyl-coated chain link fencing around the base boundary of the hous-ing area.

roads n Enhance streetscapes with landscap-ing, walkways, and site furnishings.

n Use roadway features such as smaller radius corners and narrow street widths to reduce traffic speeds in residential areas.

walkways and paTHs n Emphasize pedestrian and bicycle circulation within housing areas and connect housing to community facili-ties.

n Use concrete pavers to emphasize major crossings.

n Provide landscaping, pedestrian-scale lighting, seating, and other basewide site furnishings along walkways.

n Use concrete or bricks for patio proj-ects.

ligHTing and uTiliTies n Provide pedestrian-scale lighting fix-tures throughout housing areas.

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

The Air Base is divided into three distinct architectural districts: Basewide, Flightline / Industrial, and Residential (see the map above).

Joint Base Charleston General Design Standards shall be applied to all projects. When a project is located in the Air Base Basewide or Flightline / Industrial District more specific standards from those sections of the ACP shall be applied. Guidelines for the Residential District are found in the General Residential Design Standards.

New buildings shall conform to these stan-dards to create an overall campus feel to the Joint Base Charleston Air Base wall sysTeMs

Brick n Use brick installed per the General Commercial Guidelines as the promi-nent wall material.

n Use Charleston brick with precast ac-cents in walls combined with sloped roofs and pronounced eaves.

n Brick may be used when appropriate for lintels, sills, arches, or quoins. Detail-ing may be used to emulate bearing wall construction.

Architectural Precast n Precast is appropriate for lintels, sills, water tables, belt courses, and friezes.

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

The Air Base has a foundation for architectural unity. The existing archi-tecture depicts a predominant materials palette, a consistency of material detailing, and an acute awareness of historical design precedent. The fol-lowing design standards are applicable in addition to the general design standards, to the Air Base Basewide District, to both host and tenant organizations.

They are based on the existing architecture and encourage contemporary adaptations of the vernacular.

architectural compatibility plan - Air Base30

Concrete Block n Use 8x8x16 split-faced concrete block where allowable and install per the General Commercial Guidelines.

Stucco n Stucco is allowable per the General Commercial Guidelines.

Other Materials n Use other materials per the General Commercial Guidelines.

rooF sysTeMs n Hipped roofs are preferred for most buildings. Gabled end walls with sloped parapets and horizontal flanks may also be used. Flat roofs with continuous par-apet walls are discouraged and should be limited to special use facilities.

n Gabled elements are encouraged at entries and to break up large masses.

n Metal roofing should be dark bronze.

n Provide parapet walls with precast cap for low sloped roofs and gable ends.

windows and doors n Windows and doors should follow the General Commercial Guidelines.

screens and enclosures n Provide screening and enclosures per the General Commercial Guidelines.

The flightline encompasses aircraft hangars and maintenance facilities.

This area uses simplified industrial detailing for massive buildings. Build-ings should be designed with forms, materials, and color palettes similar to those of the Air Base Basewide district, but with simplified detailing more befitting their function.

flightline / industrial district general

Follow the JBC General Industrial Design Standards with the additional requirements listed below:

Buildings n Observe all horizontal and vertical safety restrictions along the flightline.

n Lower the apparent height of hangars and warehouses by arranging single-story spaces along the perimeter in high-visibility areas.

wall sysTeMs n Use brick on all one- and two-story buildings in high-visibility areas.

n Flightline security walls should be coordinated with the design of adjacent facilities or the immediate context.

rooF sysTeMs n Low-slope roofs are allowed for very large volumes or accent sub-masses.

n All small structures or small attached areas to larger structures must have a high slope. Use hipped or gabled roof forms for the majority of areas. Curved roof forms are acceptable in a case by case basis.

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

The Weapons Station, as laid out in the master plan, is divided into eight distinct districts: West Side, East Side, North Side, Waterfront, South Annex, Housing, Marrington and Ordnance. Additionally, there are several overlay zones that provide specific standards for those areas that do not directly line up with the district boundaries. In addition to these districts and overlays, there is the Short Stay Recreational Area on Lake Moultrie. This remotely located recreational area includes existing cabins, villas, campsites, picnic pavilions and a conference center. The Marrington District should be used as a guide for any new structures or renovations to this area.

General and specific design standards for all buildings are included in the JBC General Site and Building Standards. The more specific standards from the District and Overlay Sections of the ACP shall be applied.

The East Side & West Side Districts form the Central Core of the JBC Weap-ons Station with Red Bank Road forming the principal artery. The West Side District forms the principal entrance to the Weapons Station consisting of mostly community, support and recreational facilities. The East Side District lies behind the main security gate and consists of mostly administrative and maintenance facilities. A golf course comprises a good portion of this district.
