Pittsburgh IAP ARS General Plan 2012

August 2012

APPENDIX B – DESIGN GUIDELINES

The Pittsburgh IAP ARS Design Guidelines are intended to provide architects, landscape architects, planners, and engineers with specific guidance concerning construction projects proposed for Pittsburgh IAP ARS. The intent of the Design Guidelines is to improve the appearance of the installation through more effective planning and a consistent use of materials, architectural details and landscaping.

By adhering to the Design Guidelines, Pittsburgh IAP ARS will develop a recognizable “sense of place” that reflects the design vernacular of Western Pennsylvania and improves the overall aesthetic of Pittsburgh IAP ARS for the long term. Overall, Design Guidelines inform future construction activities by providing development standards. These standards address architecture, circulation, landscaping, lighting, signage, site furniture, and color scheme. Each element is designed to relate to the others in order to create a cohesive, unified design aesthetic. The guidelines may refer to examples to demonstrate design intent, but Pittsburgh IAP ARS does not endorse any manufacturer or product over another.

B.1 OB J E C T I VE S

The following design objectives were established to assure design consistency throughout Pittsburgh IAP

ARS:

Clean lines and simple architecture for buildings Adaptable façade treatments for different functional uses which retain the overall aesthetic Exterior finishes match latest buildings under construction.

Reflect Western Pennsylvania style in use of colors, materials, landscaping, signage, lighting, and site furniture.

Use native Western Pennsylvania plant material sourced from within 50 miles of Pittsburgh IAP ARS for landscaping.

B.2 WE S T PE N N S Y L V AN I A AR C H IT E C T U R A L DE SIG N

IN F L U E N C E S

West Pennsylvania was colonized in waves by a variety of European immigrants who brought with them their own culture, heritage, and sensibilities. The Pittsburgh area has several distinct neighborhoods that are defined by this history. The eclectic nature of these neighborhoods does not lend itself to standardized building construction design for the AF. Therefore, it is appropriate for Pittsburgh IAP ARS to follow basic, modern brick and mortar building design themes with concrete block details. The purpose of the architectural design guidelines is to set aesthetic design standards for new construction and renovation.

The goal is a unified character reflected throughout the entire cantonment. The guidelines should be flexible enough to be suitable for a variety of installation uses and budget requirements. Buildings should be appropriately designed with regards to size, scale, mass, materials, and color scheme. Renovation projects should upgrade building exteriors to comply with the design standards. The following concepts have influenced the guidelines:

Cluster building patterns to reinforce a campus setting.

Design buildings that account for local climatic conditions.

Design architectural details common to all buildings.

Create visual interest by using projected or recessed covered entrances.

Limit building width to 50 feet for administrative buildings to allow interior day-lighting.

Define pedestrian entrances with porticos to reinforce the human scale and way-finding, Maintain UFC required standoff distances for vehicles.

SOW Attachment 4

B.3 CI R C U L AT I O N

The guidelines encourage a circulation pattern on base that creates a well-defined hierarchy of roads and sidewalks that improves safety and way-finding.

The transportation network on Pittsburgh IAP ARS is defined by the natural topography. The steep topography does not allow for a traditional grid pattern, but the existing roads and sidewalks make optimal use of the land. There is a hierarchy of roads and sidewalks which are clearly defined. The GP identifies an opportunity to improve and enhance the pedestrian circulation plan. This opportunity involves extending the sidewalk along Defense Avenue to the main gate, thereby improving pedestrian safety. A further discussion of the circulation system can be found in Chapter 4. Guidelines for the circulation on Pittsburgh IAP ARS are as follows:

B.3 .1 RO A D S

Primary roads shall be designed and maintained to accommodate the heaviest flow of vehicle traffic on and off Pittsburgh IAP ARS.

Secondary roads shall be designed and maintained to provide access to parking adjacent to all functional areas.

Tertiary roads shall be designed and maintained to provide access to flight line operations, maintenance, and other specialized storage areas.

B.3 .2 PA R K I N G

Parking areas shall be designed and maintained to allow head-in parking only.

Parking lots shall be 60 feet wide total. This includes a 24-foot travel aisle and 18-foot parking bays on either side of the travel aisle.

Parking spaces shall be 9 feet wide by 18 feet deep. Parking spaces shall be pervious asphalt to help reduce pollutant load and improve water quality.

Handicap spaces shall comply with the 2010 Americans with Disabilities Act Standards for Accessible Design, September 15, 2010.

B.3 .3 S E R V I C E Dumpster containers shall be conveniently located near the facility they serve and comply with

UFC.

Dumpster containers shall be enclosed with standard beldon brick with concrete masonry unit block walls and plastic lumber planks. Evergreen landscape material shall be used to further block views of the trash collection areas.

Avoid dumpster locations adjacent to main roads and sidewalks.

B.3 .4 PE D E S T R I A N S

Sidewalks shall be provided on at least one side of the primary road and all secondary roads. These shall connect to building entrances, parking areas, open spaces and plazas.

Sidewalks at building entrances shall be widened and complemented with appropriate landscaping to create a sense of place and arrival.

Sidewalks shall comply with the 2010 Americans with Disabilities Act Standards for Accessible Design, September 15, 2010.

Special paving shall be reserved for important entrances to buildings such as the main entrance to the Wing HQ and TFF/CAC.

Crosswalks shall be provided at important or heavily used crossing areas. They shall be clearly marked with specialty paving or striping, signage, and cautionary lights.

Specialty paving and intensive landscaping shall also be used at recreational courtyards and pedestrian plazas to define these outdoor spaces as distinct from sidewalks and enhance the experience.

Canopy trees shall be used along both sides of the primary road.

Gathering spaces shall be intensively landscaped using plants from each classification of the plant palette.

B.4 LAN D SC API N G

Landscape design is an integral part of the GP. Properly designed landscaping reinforces circulation and complements architecture. It defines pedestrian spaces and provides protection from the elements.

Consistent landscape design visually ties the entire installation together and provides the added benefit of a coherent and pleasant experience. The guidelines for landscaping are as follows:

Incorporate existing landscaping into future landscape plans.

Require all landscaping to be native to Western Pennsylvania and sourced from within 50 miles of Pittsburgh IAP ARS.

Reinforce vehicular and pedestrian circulation by using a hierarchy of landscape materials.

Provide separation between pedestrian and vehicle traffic where possible.

Buffer unsightly elements, such as dumpster containers, with screening plants.

B.4 .1 CA N O P Y T R E E S

A canopy tree is typically taller than 30 feet and has a broad crown and dense foliage. “Shade” tree is a common alternate name. Canopy trees have multiple applications in the landscape, such as parking lots, open areas, and parks. They can be planted singly as specimens to be viewed as focal points or informal groups to recreate natural forest stands. Canopy trees are excellent along walkways as they protect pedestrians from harsh summer sun. Most canopy trees are deciduous, which means the tree drops its leaves in autumn.

B.4 .2 SC R E E N I N G T R E E S

The purpose of a screening tree is to hide or block a person’s view of a particular unsightly or objectionable object. Screening trees are typically from 15 feet to 30 feet tall (or taller) with dense branches and foliage extending the entire length of the trunk. Most screening trees are evergreen;

however, some deciduous trees have extremely dense branching habits that make them suitable as screens. Typically, screening trees are planted in linear rows effectively forming a vegetated wall blocking any view of what is beyond the trees.

B.4 .3 AC C E N T T R E E S

Accent trees come in a variety of sizes and shapes and provide color and seasonal interest to the landscape. An accent tree may produce an abundance of colorful flowers when in bloom. Many deciduous accent trees have colorful displays in autumn when the leaves change before dropping. Some accent trees have interesting shapes or bark characteristics that stand out.

Accent trees can be massed in groups with screening trees used as a backdrop. A mass of accent trees multiplies the overall effect, and the screening trees reinforce the visual display. Along pedestrian paths and outdoor plazas, these trees reinforce the human scale and provide opportunity for interaction or contemplation.

B.4 .5 SH R U B S

Shrubs represent a large group of woody plants with stems and leaves, either evergreen or deciduous.

Height, spread, flower, fruit, light and soil conditions vary between species. Shrubs have many applications in the landscape such as pruned hedges in parking lots or in massed display along sidewalks and other outdoor areas. Hedges provide a uniform appearance and can screen unsightly areas. Massing is an effective use of shrubs that bloom or have unique foliage.

B.4 .6 GR O U N D C O V E R

Ground covers are the final touch on a landscape, similar to wainscoting inside a building. It completes the landscape design and provides continuity throughout the installation. As the name implies, it is a low growing group of herbaceous, perennial, or woody plants typically less than 3 feet in height. Ground covers are evergreen and some flower, but they are grown mostly for the foliage.

Path lighting promotes safety and way-finding for pedestrians. To the greatest extent possible, lighting shall be projected downward to prevent light pollution.

B.6 SIG NAG E

Pittsburgh IAP ARS currently has a well-defined and consistent signage design employed throughout the cantonment. The purpose of a sign is to convey information. It must be visible, legible, and appropriate for the design context of its surroundings. The location, size, layout, length, and typeface are important considerations for signage.

There are three types of signs: informational, directional, and regulatory. The sign system for Pittsburgh IAP ARS shall be uniform in its use of color, material, and style. The guidelines for signage on Pittsburgh IAP ARS are as follows:

The sign system shall be coordinated, consistent, flexible, and economical for a uniform appearance.

This federal manual is the national standard and is approved by the Federal Highway Administrator.63 The poles and backside of these signs shall be painted with Pittsburgh IAP ARS approved accent color for consistency.

B.7 SIT E FU R N IT U R E

Guidelines for site furniture establish a coordinated approach to selecting furnishings that reflect Western Pennsylvania and meet the needs of Pittsburgh IAP ARS. Site furniture can be benches, tables, bicycle stands, fencing, or flag poles. Typical guidelines for site furniture state that it should be:

complementary to adjacent building style and color;

durable to Western Pennsylvania conditions;

easy to maintain;

low maintenance; and vandal resistant.

B.7 .1 BE N C H E S

Only one type of bench shall be used on Pittsburgh IAP ARS. The bench shall be light colored wood to deflect heat such as Cranston Material Handling Equipment Corporation’s Heritage Cedar Recycled Plastic Bench with Cast Aluminum Frame, product #434-2003. Benches will provide seating at primary building entrances, drop-off zones, congregation points and other high activity areas. A minimum distance of five feet should occur between the seating edge and any stationary obstacle such as a sign post. Vegetation installed near seating should not conflict with access to seating or in the use of seating.

Avoid plants that can stain or cause harm, otherwise, check the approved plant list for appropriate species.
