Introduction

Building 1709

Building 1725

Outdoor Pavilion

The Architectural Compatibility Plan (ACP) defines a clear design vocabulary to be used throughout the Base, providing specific standards for all aspects of exterior and interior design.

Compatible architecture is accomplished with similar buildings, using common design forms, details, materials, site features, landscaping, and streetscapes.

Quality and compatibility are achieved through creating 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 development at Hanscom 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.

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, planners, architects, engineers, and maintenance staff. It promotes clear, concise communication between the Hanscom 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 Hanscom AFB Installation Development Plan (IDP) as a key component plan.

How to Use This Plan

The ACP defines five architectural settings:

Basewide, Industrial, Research and Development, Administrative, and Community (refer to map in Appendices).

General and specific design standards for all buildings are included in the Basewide setting.

Basewide standards shall be applied to all projects, including the Lincoln Labs Campus.

When a project is located in the Industrial, Research and Development, Administrative, or Community 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, and highlights the importance of site analysis. The implementation 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, colors, and landscape materials; a development zone map; basis of design products; reference publications; typical wall sections; and a checklist for project personnel. Use the Appendices in conjunction with the general text of the ACP as a quick reference to specific materials and color specifications.

LIGHTING

Exterior lighting is a system that directly impacts the visual qualities of the Base. By day, the fixtures and poles add visual character and rhythm to the streetscape. At night, they contribute to the perception of safety and comfort. Use consistent components throughout the Base.

Develop building lighting as an integral part of the facility design.

General

• Use sub-surface electrical lines to feed exterior light fixtures.

• Use Light-Emitting Diode (LED) luminaires for all applications.

• Use ETL-12-15 (2012) compliant fixtures for all applications.

• Photometric analysis is required for all fixtures and lighting design in order to ensure that light levels are adequate for safety, but are not excessive.

Streets

• All classifications of roadways should use the same luminaires and poles.

• Each classification of roadway should use a consistent mounting height.

• Use 20’ to 25’ height bronze finish aluminum poles and arm-mounted, architectural shoebox-style luminaires.

• Equally space poles on sides of roadways.

Parking Areas

• Use multiple luminaires on a single pole to reduce visual clutter and maintenance.

• Coordinate pole placement with landscape island locations, and utilize landscaping to visually screen concrete light pole bases.

• At small parking lots, use 15’ to 20’ height bronze finish aluminum poles and shoebox-style luminaires.

• At large parking lots, use 20’ to 30’ height bronze finish aluminum pole with multiple-luminaires.

UTILITIES

Reducing the negative impact of utilities reduces the visual clutter of the base thereby allowing the eye to focus more clearly on the other, more aesthetic elements of the landscape. Removing or relocating utility lines and equipment from the most visible areas of the installation will improve the overall character.

The elimination of power poles and overhead distribution lines reduces maintenance and repair costs by reducing exposure or vulnerability to damage.

Electrical service drops, panel boxes, transformers, and meters detract from building design. The objective is to design these necessary services as an integral part of a structure. Similar design solutions should be repeated as appropriate.

Additions, alterations, and repairs often produce unsightly utility solutions and must, therefore, adhere to unified guidelines. Addition, alteration, and repair projects can serve as opportunities to improve existing unsightly installations.

Electrical substations, power poles and overhead distribution lines create visual clutter at the entrance to a Base.

Utility Lines

• Place all pole mounted utility lines and building feeds underground.

• Use every opportunity to bury utilities.

• Exposed conduits, cables, and wires are not permitted.

Utility Structures

• Avoid free standing utility structures where possible.

• Use underground vaults for equipment where possible.

• Locate pad mounted equipment in less visible areas and screen with landscaping or screen walls.
