Architectural Compatibility Guide For Cannon Air Force Base

Command Policy

As stated in the AFSOC Facility Excellence Guide, “Regardless of use, all facilities on the installation must be efficient, healthy, safe and comfortable places to work and play”. In addition, the Air Force seeks to:

Incorporate “Principles of Smart Growth” in planning installation development.

Foster a strong sense of place for each installation through architectural compatibility and people friendly site design.

Provide quality facilities that achieve very high levels of sustainability and energy efficiency.

Pursue compact and efficient building designs that minimize land use and reduce costs.

Utilize cost effective, durable, low-maintenance materials with natural or integral colors.

Reuse existing infrastructure, facilities and raw materials to the maximum extent possible.

Incorporate landscaping principles to preserve or restore native vegetation and natural ecosystems and to minimize water usage.

The Purpose

This document establishes architectural and site design standards, often referred to as the Standard, for Cannon Air Force Base (CAFB). It encourages creative but practical design solutions to accommodate the growing mission requirements of the 27th Special Operations Wing (27SOW).

Specifically, it aims to improve the function and appearance of new and existing facilities, moderate construction and maintenance costs, achieve energy-efficiency and sustainability, and strengthen the overall architectural compatibility of the base.

This document should be understood by all persons involved in the design, construction or maintenance of base facilities. Its provisions will be enforced through standard review and approval procedures during project programming, planning, design and documentation, construction and occupancy.

These guidelines shall be applied to all MILCON and O&M projects at CAFB regardless of funding source or client organization.

As the Air Force mission dictates, this document will be periodically updated and revised.

Cannon AFB today is architecturally diverse

The Cannon Flightline

Page 6 Cannon Air Force Base January 17, 2013

Achieving Design Excellence

This section outlines the actions necessary to implement the Standards:

1. Distribution of the Design Standard

The Standards will be circulated among the installation leadership including all commanders of significant tenant organizations, all Architectural and Engineering (A-E) firms working on CAFB, the Army Corps of Engineers (COE) and throughout the civil engineering division including operations, branch chiefs, architects, engineers and planners. Copies will be provided to Headquarters of the U.S. Air Force Special Operations Command (HQ AFSOC) for review and coordination. A digital copy in portable document format (PDF) will be available on a publicly accessible folder at the CAFB website. Digital copies may be distributed to A-E firms and other contractors outside the base via CD/DVD or email.

Hard copies will be made available on a limited basis.

2. Enforcement of the Design Standard

These Standards will be enforced by the 27 SOW/CC or his/her designated representative. In the absence of any other designee, the Base Architect shall be assumed to be the representative. Any deviations from these Standards are subject to approval by the 27 SOW/CC or his/her designated representative during the course of project review. Deviations should be limited to necessary exceptions resulting from special programming requirements or new developments in building materials and technology.

3. Engagement of Design Professionals

Engagement of talented providers of A-E services is essential to the successful implementation of these Standards. Because of the substantial scope of new construction planned for CAFB, consideration should be given to extending design contract opportunities to a greater number of A-E service providers as a means of bringing new talent and ideas to the development of the base.

Design-Builders are expected to provide the same level of service and design excellence as A-E service providers.

4. Design Development and Review

A-E service providers and Design-Builders are expected to collaborate with the designated Air Force Project Manager (PM) to conduct an orderly process of design reviews.

A project design process shall typically begin with a kick-off meeting of interested parties to discuss and confirm program requirements and to establish general design parameters. Subsequently, at scheduled intervals, A-E service providers will submit design progress drawings, renderings or models for review, comment and ultimate approval by appropriate personnel.

Refer to Appendix B for submittal requirements during the phases of project design.

The Visual Districts

Visual Districts are areas of the base where buildings have similar characteristics derived from the common function, form, scale, color, and texture of the facilities within each District.

CAFB can be divided into three Visual Districts: the Community Center, the Northwest Flightline and the Southeast Flightline.

District 1: The Community Center

The Community Center District is effectively the Town Center for military and civilian residents and workers. It includes administrative buildings, medical facilities, the Commissary/BX, a gas station and convenience store, a library, dry cleaners, a child development and youth activity centers, banks, dormitories and various other amenities. This District is located near the main gate, between a traditional residential neighborhood to the northwest and various facilities supporting the flight line to the southeast.

The Area Development Plan for this District includes substantial demolition and new construction over the next decade as improvements are made to accommodate expected new arrivals. This new development presents an excellent opportunity to transform the Community Center District into a more attractive, sustainable and pedestrian-friendly neighborhood.

The most prevalent exterior wall materials in this District, in various colors, are modular brick, concrete block and stucco. Roofs vary from concealed, low-slope roofs to exposed, medium-slope standing seam metal roofs in colors ranging from older dark brown to the newer red. Buildings in this District are limited to three stories in height.

District 2: The Northwest Flightline

The Northwest Flightline District is an area adjacent to the flightline that supports flight operations and training. In addition to numerous aircraft hangers, this District includes squadron operations facilities, administrative offices, buildings for flight simulators, training, storage and other industrial uses. Future development in this District will primarily relate to administrative and training functions and flightline support activities.

Large metal-sided aircraft hangers along the flightline notwithstanding, the most prevalent finish materials in this District are stucco, modular brick and concrete block of various colors and textures. Several low cost, temporary buildings with painted panel siding are also evident. Standing seam metal roofing is commonly used. Roof colors vary from white to dark brown to newer red.

District 3: The Southeast Flightline

The Southeast Flightline District is a large, developing area adjacent to the flight line. Significant new development is planned for this District that will support nearly every aspect the Air Force mission.

Projects in this District utilize an architectural style derived from historical southwestern and Spanish Colonial influences. It is the stylistic basis for all future projects at CAFB.

What is Architectural Compatibility?

According to the AFSOC Facility Excellence Guide, architectural compatibility exists when architectural features are “compatible in function, mass, shape, color and texture”.

The Oxford English Dictionary defines compatible as meaning, “able to exist or occur together without conflict”.

CAFB consists of a diverse variety of buildings that reflect the program needs, design values and technologies of the times in which they were built.

As a result, there is presently no single, unifying design style for the base. However, compatibility does not require uniformity. Architectural compatibility can still be gradually achieved through the use of a limited set of building forms and materials that can exist together without conflict. This Standard describes the basic forms and materials acceptable for use at CAFB.

Compatibility and Diversity

Many of our existing buildings will eventually be demolished to make room for new construction but many others will remain, possibly for decades. The challenge we face is how best to create a sense of aesthetic cohesiveness, or architectural compatibility, in which old and new buildings are able to coexist harmoniously.

Generally, forms and materials already in wide use on the base will continue to be acceptable for renovations and additions to existing buildings, but precise duplication of existing architectural features is not required. New features added to existing buildings should incorporate the new design ideas and technologies described in this Standard to enhance architectural compatibility and improve the general appearance of CAFB.

When new construction stands alone, as it will in the new Southeast Visual District, this Standard establishes a more limited set of building forms and materials.

When new construction occurs in close proximity to existing buildings, borrowing and blending forms and materials from the existing buildings may be an acceptable means of establishing a visual connection between old and new. In other words, flexibility in the use of forms and materials is permissible in order to improve architectural compatibility.

While the existing diversity of our facilities is undeniable, a more architecturally unified installation remains the objective. This will be achieved over time by the consistent application of this Design Standard as defined in the pages that follow.

The Cannon Style

The renderings on this page illustrate planned and existing projects. Several new projects at CAFB utilize an architectural style derived from historical southwestern influences. It is the stylistic basis of what can be termed The Cannon Style.

The Cannon Style utilizes red, sloping metal roofs and earth-toned colors in stucco and masonry.

Additional materials recommended by project architects will be considered on a project-by-project basis.

When new buildings will be located near existing ones, architects should be mindful of opportunities to improve architectural compatibility by combining new and existing building forms, colors and materials.

Campusing

Campusing creates opportunities to resolve Anti-Terrorism and Force Protection (ATFP) requirements at the site perimeter so that buildings can share relatively secure, landscaped common areas and other amenities such as auditoriums, classrooms and break areas. Campusing can improve the feasibility of cost and energy-saving amenities such as rainwater collection for irrigation, geothermal and ice storage cooling systems, and photovoltaic arrays.

Campusing requires careful cooperation among all Air Force organizations involved in facility planning, programming, funding, contracting, design and construction at CAFB.

The Design Standard

General Requirements

1. This Standard is applicable to all new building projects and all major renovations or additions at

CAFB.

2. The International Building Code (IBC) and all compatible specialty codes issued by the

International Code Council (ICC) are applicable to all facility design and construction projects at CAFB. The latest versions of the IBC codes adopted by the Air Force (AF) and in effect upon commencement of design services shall remain valid provided construction begins within one year of design completion. If the one year period is exceeded, the Air Force PM or Contracting

Officer’s Representative (COR) may require adjustments to the project design to accommodate a newer code, for which additional design fees may be warranted.

3. All new facilities, parking lots and sites shall be accessible in accordance with the Americans with Disabilities Act (ADA) and Architectural Barriers

Act (ABA) accessibility guidelines unless specifically waived by the AF during the design review process.

4. All new vertical construction and significant renovations shall incorporate sustainable concepts meeting the latest USGBC LEED

Minimum Program Requirements (MPR) and shall be formally certified LEED v3 Silver (or better) with not less than 20 points derived from energy efficiency and water conservation.

5. All new vertical construction and major renovations not meeting LEED MPR shall fully incorporate the Federal requirements for High

Performance and Sustainable Buildings (HPSB).

6. Room sizes for all occupancies shall conform to limits defined in Air Force Manual

AFMAN 32-1084 - Facility Requirements.

7. Anti-Terrorism and Force Protection (ATFP) requirements will be established during early design phases in coordination with the base Anti-

Terrorism Officer (ATO). Refer to Unified Facilities Criteria UFC 4-010-02 - DOD

Minimum Anti-Terrorism Standards for Buildings for specific information.

8. Fire Protection: Per UFC 3-600-01 - Fire

Protection Engineering for Facilities, buildings that have alteration, modernization, modification, rehabilitation, and renovation costs equal to or exceeding 50% of the replacement cost of the building, must bring the entire building into compliance with new construction requirements.

(The estimated replacement cost is exclusive of the costs to bring the building into full compliance.) Facilities in which alteration, modernization, rehabilitation, and renovation work is less than 50% of the replacement value, the building must comply with the criteria in this

UFC for new construction, to the maximum extent practical. All new work accomplished as part of alteration, modernization, modification, rehabilitation, and renovation actions/projects must meet the requirements for new construction.

9. Refer to the CAFB Electrical Standards for building and site electrical requirements.

Planning

10. Campusing multiple projects should be considered early in the planning and programming stages. Coordination and consolidation of site and utility requirements among several buildings may enable the use of various sustainable systems by sharing system costs and advantages among several buildings.

11. Related occupancies should be consolidated within single buildings to the maximum extent practical.

Building Design Basics

12. Every project must incorporate efficient use of materials, systems and assemblies to minimize complexity, improve constructability, reduce

Page 12 Cannon Air Force Base January 17, 2013 maintenance requirements and achieve the necessary performance at minimal cost.

13. Building forms should be simple with a linear, horizontal emphasis derived from roof lines, fenestration patterns and wall materials.

14. Buildings should be designed to engage public streets and sidewalks at a human scale through the use of materials, detailing and transparency (within the parameters of security requirements).

15. To the maximum practical extent, develop compact and efficient floor plans to reduce building footprints, construction costs and land consumption. Two and three story buildings are permitted. All buildings shall be fully accessible unless specifically waived by the AF.

16. Open floor plans in office and shops areas that are readily adaptable to different uses and space allocations are strongly preferred.

17. Ceiling heights and building floor plan depth should be considered to maximize natural daylighting per LEED Indoor Environmental

Quality (IEQ) Credit 8.1.

18. New projects will utilize exterior materials identified in Appendix A. Other materials will be considered on a case by case basis.

Renovations and additions to existing buildings may utilize exterior materials that are identical or complementary to existing materials.

19. Interior mechanical rooms are preferred and strongly recommended. If necessary, mechanical equipment may be located on the building roof or on the ground. Ground locations will require an enclosure and compliance with UFC 4-010-01 - DOD

Minimum Anti-Terrorism Standards for

Buildings. (See Roofs section for rooftop equipment access requirements.)

Building Entrances

20. Primary building entrances should be clearly recognizable, sheltered from the weather and accessible. Entrance elements that are highly transparent and formally external to the main structure are encouraged. Primary entrance storefront frames shall be aluminum with integral thermal-breaks.

21. Secondary building entrances should be clearly recognizable, accessible and provide shelter from the weather but should be less prominent than the primary entrance.

22. Service entrances and loading docks should be located away from main entrances and provided overhead protection from the elements. Hollow metal service doors and frames should be painted to match adjacent wall surfaces.

23. Elevators, if provided, shall be located near the front entrance and immediately visible to visitors.

All elevators shall be capable of accommodating an emergency gurney.

Windows and Doors

24. In normally occupied spaces with exterior walls, windows shall be designed and located to provide natural daylighting, fresh air, abundant views to the outdoors and adjacent outdoor gathering areas (within the parameters of security requirements). As a general rule of thumb, window area should equal at least 20% of the room floor area.

25. Window curtain walls and storefront systems are permitted. In some instances, curtain walls will be required to meet anti-terrorism requirements as defined by UFC 4-010-01.

26. Windows may be operable in locations accessible from the building interior and in rooms normally occupied (within the parameters of security requirements). Operable windows shall not open more than 4 inches unless a larger opening is required for emergency egress. Exterior screens firmly secured to the window frame are required

January 17, 2013 Cannon Air Force Base Page 13 for all operable windows.

27. Recommended ranges for glazing design values are as follows:

a. U Insulation Value: U ≤.35

b. Solar Heat Gain Coefficient: SHGC ≤.51

c. Visible Light Transmittance: Tvis ≤ 62%

Glazing design values should be carefully selected to balance the desired levels of thermal performance, privacy and transparency. Generally, greater transparency is preferred.

28. Window shading structures are recommended for curtain walls and large south-facing windows. Shading structures may be internal or external to the building.

External shading structures shall be permanent and constructed of factory-coated aluminum or steel.

29. External and internal window shading structures shall be designed and permanently installed to appropriately manage natural light and solar heat gain in both summer and winter. If additional light control is needed, retractable translucent or opaque window blinds or other interior window treatments should be included in the building furnishings.

30. Skylights, clerestory windows and tubular daylighting devices (such as Solatube) may be utilized to provide natural daylight to interior spaces. (Care must be taken to locate, detail and install natural light sources to prevent leaks and air infiltration.)

31. Glass block, translucent glazing and translucent fiberglass panels (such as Kalwall) are allowed wherever natural daylighting and interior privacy are desired.

32. Emergency egress doors that are not part of a primary or secondary entrance shall have hollow metal doors and frames painted to match adjacent wall surfaces.

Exterior Walls

33. Exterior walls shall have an average insulation value of R-19 and a vapor barrier located at the interior side of the wall assembly.

34. Foundations and slabs shall incorporate an integral thermal break or include perimeter thermal insulation at all occupied spaces.

35. Structural wood framing, metal framing and steel structures with non-bearing metal stud walls are preferred over bearing masonry.

(Stud walls allow for simpler and more cost effective installation of insulation, electrical wiring and devices, plumbing lines and finish materials at a lower relative cost.)

36. Brick and concrete block veneer are the preferred exterior wall finish materials.

Multiple colors and combinations of 4 inch and 8 inch courses and split-face, smooth-face or ground-face textures are encouraged to create visual interest. Standard masonry colors are listed in Appendix A. (Painting of new exterior masonry is not permitted.)

37. Stucco (aka, Portland Cement Plaster) may be used when masonry is inappropriate or exceeds budget limitations. When used, stucco shall utilize a mesh-reinforced, three-coat system with control joints spaced roughly

12 feet on center horizontally and vertically or approximately every 144 square feet. The distance between control joints shall not exceed 18 feet. Control joints should be logically located at corners, long spans and large surfaces in patterns that relate to building fenestration and forms.

In areas of the building wall surface particularly vulnerable to cracking, the use of mesh reinforcing and fiberglass admixtures is required. In all cases, stucco shall be applied to rigid substrates (masonry, concrete or rigid sheathing over metal or wood framing) to minimize cracking and reduce surface warping. Care must be taken during stucco installation to compensate for high winds and

Page 14 Cannon Air Force Base January 17, 2013 temperatures that may accelerate drying time and increase cracking.

38. Stucco shall have a medium dash texture with integral color mixed into the finish coat or an elastomeric color coat.

39. Exterior Insulated Finish Systems (EIFS) shall utilize a reinforced, impact resistant assembly consisting of a two or three coat stucco finish. (Soft, elastomeric color coats are not acceptable except when applied over stucco.)

40. Metal panel siding is approved for use on hangars when located 8 feet or more above finish grade. Panels shall be an insulated sandwich-type with an embossed exterior surface. Use of metal panels on other facilities is discouraged and subject to approval by the 27 SOW/CC or his/her designated representative.

41. Exposed Fastener Composite Wall Panels (such as Northclad EF Panel System) may be permitted as an accent material.

42. Fiber cement board planks and panels applied to wood framing and sheathing may be permitted at approved locations.

Roofs

43. Roof assemblies for normally occupied buildings shall have an average insulation value of R-30 or more with a vapor barrier located at the interior side of the roof insulation or integral to the roof assembly.

44. Metal roofing shall be a steel standing seam system with a factory-applied color coat matching “Colonial Red” by Petersen Aluminum.

(See Appendix A: Exterior Building Materials List)

Standing seams shall be spaced no less than 16 inches apart and shall be no less than 1-1/2 inches in height. Metal roofs more than one-story above grade shall have matching snow guards, gutters and downspouts unless specifically waived during design review.

45. For metal roofing, a 4:12 roof pitch is standard.

46. Replacement metal roofing on existing structures such as hangars and warehouses having less than a 2:12 slope must be specified, detailed and warrantied for low slope applications.

47. Metal roofs shall have minimum eave overhangs, measured horizontally from the surface of the exterior wall to the roof eave fascia, as follows:

One Story - 2 feet

Two or More Stories - 3 feet

48. Low-slope roofing shall be a 60 mil, White, TPO

(Thermoplastic Polyolefin) fully-adhered membrane system. For low-slope roofing, a 1:24 roof pitch is standard unless specifically waived during design review.

49. Low-slope roofs shall be bounded on at least three sides by parapet walls and shall drain to through-wall scuppers or to a roof edge with a gutter and downspout(s). Internal roof drains shall be located to prevent freezing and shall be cast iron or insulated PVC to prevent noises in occupied interior spaces.

50. Through-wall overflow scuppers are standard.

When necessary, overflow drains may be piped internally and shall daylight 12 inches above grade.

51. New buildings may have a combination of standing seam metal and low-slope TPO roofs.

52. Renovations or additions to existing buildings may utilize existing roof forms, materials and colors in visible locations.

53. At all roof downspout outlets, provide splash blocks or Rip Rap channel to facilitate proper discharge to planned detention areas or storm drainage systems as approved by CAFB.

54. Where roof drainage crosses a sidewalk, provide underground piping or a trench with a removable cover plate so that flow occurs underneath the walking surface. (Ice build-up on sidewalks and landings must be avoided!) Provide a Rip Rap channel to facilitate proper drainage away from the building.

January 17, 2013 Cannon Air Force Base Page 15

55. Rooftop equipment is permitted. If rooftop equipment requiring periodic maintenance is necessary, a low slope roof area for placement of the equipment is required. In addition, secure roof access shall be provided from a room within the building interior. Access shall include a permanently installed ladder, ships ladder or stair and lockable roof hatch. Permanent walking pads or pavers must be provided from roof access points to and around all rooftop equipment requiring periodic maintenance.

56. Where rooftop equipment is located in publicly visible locations, high parapets or screen walls are required.

57. Any rooftop mechanical equipment with moving parts shall be placed on supports capable of damping and isolating vibrations from the building structure.

58. In buildings with three or more stories, at least one secure roof access shall be provided by continuation of a stairwell from grade level to above the roof level. If the stairwell is enclosed, it shall be enclosed for its entire height.

Site Design

Objective

Good site design will create attractive and sustainable outdoor spaces that enhance the appearance of each building and the pedestrian connections between them. It will incorporate native vegetation with minimal irrigation and maintenance requirements, and use natural, durable materials and permeable surfaces to the greatest practrical degree.

In addition, good site design will create functional and efficient vehicular circulation, and provide well illuminated parking areas and pedestrian pathways.

General Requirements

1. Per UFC 4-010-01 – DOD Minimum

Antiterrorism Standards for Buildings, site design shall incorporate security provisions, if required, such as walls, fences, gates, berms or other barriers as determined during project design review. Refer to Page 16, Barriers, Screens and

Enclosures for additional information related to

Site Design.

2. Site Signage: Free-standing monument and marquee signage shall conform to the CAFB standard illustrated below. For other signage, including temporary construction signage, refer to UFC 3-120-01 - Air Force Sign Standard.

3. Each project shall provide adequate parking for occupants and visitors in accordance with the Architectural Barriers Act (ABA) for the

Department of Defense.

4. Outdoor seating and gathering spaces are desired for most normally-occupied buildings. Outdoor spaces shall be observable and readily accessible from the building, include hard-surfaced and porous areas, provide both sunlit and shaded areas, and be shielded from wind and public view by low walls and landscaping. The use of stained or stamped concrete in these outdoor areas is permitted.

5. Refer to the CAFB Sustainable Landscape Development Plan for a list of recommended plants and other landscaping requirements.

Xeriscaping for low-water usage is required except in prestige areas as noted below.

(assume a maximum overhang of 2 feet and sidewalk width of 7 feet or more). In such instances, the parking stall length may be reduced by 2 feet.

43. Parking lot layout shall permit vehicles to easily turn around within the boundaries of the parking

Page 22 Cannon Air Force Base January 17, 2013 lot. (Dead-end, two-way drive lanes with 90° parking for 20 or fewer vehicles may use the drive lane to turn around. Dead-end angled parking drive lanes are prohibited.)

44. The visual impact of parking lots shall be minimized by the placement of the lot on the site by the use of landscaping, berms, site walls and other built elements along primary and secondary roadways.

45. Landscaping: Landscaped or Xeriscaped areas equal to approximately 10% of the paved parking lot surface should be provided. Refer to the CAFB Sustainable Landscape Development Plan

2012 and Technical Manual TM 5-803-13 for additional information.

46. Shaded parking is preferred. Shade may be created by any combination of large trees or man-made shade structures.

47. Parking lots for 100 or more vehicles shall be designed with islands for shade trees at regular intervals of 10 parking spaces or less. New shade trees should be selected and located to provide shade for at least 10% of the parking area after

10 years of growth.
