Purpose of the project

The Air Force Academy Cadet Chapel carries profound meaning to the Air Force Academy, the Air Force, and the American people.

The chapel serves an inspiring place of worship for the faculty, cadets, alumni, and guests.

This important landmark continues to be one of the most visited landmarks in the state of Colorado, representing the Air Force, the Academy, and the distinctive architectural heritage of the academy campus.

The chapel is widely renowned as a celebrated example of mid-century modern architecture, justifying a place on any list of architectural treasures, earning it’s place as a National Historic Landmark.

We are here today not to alter the visit of the architect Walter Netch, but to repair damage and protect this building for future generations of Cadets and Americans.

We have set aside time today for a guided tour of the chapel, but be aware that the chapel is accessible during public visitation hours, and further site visit is welcomed.

Solicitation Summary 2-Step Evaluation Process Rules of Engagement Anticipated Milestones Project Synopsis Performance History Current Construction Effort Scope

Chapel Layout Protestant Level Terrace Level (Catholic, Jewish, Buddhist)

Basement Level (Muslim, Choir Practice, Mechanical Rooms)

The unique structure of the chapel is worthy of commentary prior to discussing the technical requirements for this construction project.

This three story building contains three separate levels of worship. The top floor, referred to as the protestant level, contains the protestant chapel, and a protestant level balcony for choir and organ. The exterior of this level is enclosed independently from the bottom two floors, with 14 aluminum clad spires.

The terrace level beneath the protestant level contains the catholic, jewish, and Buddhist chapel areas. The catholic chapel also contains a balcony for the choir and organ.

Finally the basement level contains a muslim chapel and other support rooms, including a larger mechanical room and choir practice room.

While the protestant level is clad in aluminum and glass with a structural steel lateral and gravity support system, the floors below are structurally supported by concrete framing and concrete walls. Removal of the aluminum clad enclosure at the protestant level does not open the catholic or chapel areas to the exterior.

Design Modifications

The roof of the chapel began leaking almost immediately upon completion of the original construction. The Academy performed a multitude of design retrofits and repairs to the 1959 design, in attempts to arrest and prevent leaking. Numerous modifications were made beginning as early as 1963, including the addition of storm windows, gutters, and numerous reapplication of sealants. None of these surface level changes have arrested the leaking.

Current Design Effort

In 2015, the Air Force programmed a project to design a comprehensive retrofit of the chapel cladding to repair, retrofit, or rebuild the exterior to the extent necessary to stop the leaking. AFCEC and AFICA

The design team is led by AECOM, selected for their longstanding history of design for the Academy campus and for their extensive expertise in Air Force and DoD design and construction requirements. AECOM was joined by teaming partners Wiss Janey Elstner and Hartman Cox Architects.

AECOM teamed with Wiss Janey Elstner, a firm of engineers, architects and material scientists who work on solving building problems in the built-world, specializing in the retrofit and repair of building envelopes. WJE participated as architectural and structural engineers on this project, designing the entire envelope repair solution.

AECOM teamed with Hartman Cox Architects is a renowned Washington D.C.-based architectural firm, experienced with complex institutional projects with an expertise in managements of renovation requirements of historic buildings. Hartman Cox participated as the Historical Preservation Architect for this project.

Construction Scope

Enhance Fire and Anti-Terrorism Protection

Install Weather Resistant Panels Replace Exterior Cladding and Trim Replace Side and End Wall Glazing Restore Dalles de Verre Replace Lighting and Lath/Plaster

Repair by Replacement Elements of Facility Envelope

The primary construction scope of this project is to repair by replacement the protestant level building envelope. Options utilizing the original panels were evaluated in this design process, but were eliminated early in the design process to do challenges that were insurmountable by both cost and complexity.

Construction Scope

Restore Protestant and Catholic Organs Restore Protestant Chapel Pews Modify Electrical Systems Restore/Replace some Doors/Hardware Enhance Fire Protection

Install Fire Alarm and Mass Notification

Other Project Scope

In addition to the primary scope of replacing the walls in the protestant chapel, other more minor scope areas are included in this project.

Building Protection Ref. 3/G-310

South Entrance Protestant Choir Loft Protestant Organ Support Structure Exterior Interior

Extents of building protection to be designed and constructed by Contractor

The protestant level of the chapel will be exposed following the removal of the exterior envelope and the existing facility must be protected in its entirety prior to demolition. The contract drawings illustrate the concept of protection anticipated by the Government, but ultimately the Contractor will be required to design and install weatherproof protection for the structurally designed as indicated in the contract. Temporary HVAC, humidity control, and egress will be included in this temporary protection design.

Exterior Envelope – Side Walls

Ref. 3/A-502

SIDEWALLS –

The scope of the exterior renovation impacts all of the envelope at the protestant level chapel and above; none of the Catholic level envelope will be modified in this project other than minor door renovation. All of the existing aluminum panels and interiors will be removed from the Protestant chapel.

Asbestos-Containing Materials Abatement

LEGEND

INDICATES INTERIOR SPACES KNOWN TO CONTAIN ASBESTOS CONTAINING MATERIALS (ACM). SEE ABATEMENT NOTES.

Ref. HA-201

Removal of the side walls will necessitate abatement of hazardous materials encountered there. The grey shaded areas indicate where the hazardous materials assessment indicates that asbestos will be encountered, and assumed quantities are included in the design.

Dalles de Verre

Ref. 1/AI-313

The dalles de verre colored block glazing require careful treatment and protection during this project, and are the only visual element to be retained in the side walls. This glazing was fabricated in cassettes of 9 blocks. Approximately 1% of the blocks within the cassettes require replacement with blocks matching the original colors. All cassettes will be cataloged, labeled, and removed for storage during the renovation. The contract drawings indicate which blocks are known to require replacement or repair, and the treatment required. All of the cassettes will require restoration to clean and remove excess sealant.

Side Wall Glazing

Ref. 2/A-522

Ref. 1/A-526 Strip Windows Side Windows

Unlike the specialty preservation work required for the dalles de verre, the side wall vision glazing will be replaced in its entirety. Two glazing systems exist, the side windows in a triangular shape between lower tetrahedrons and strip windows which cover the exterior face of the dalles de verre. All new glazing will be laminated for blast resistance.

Cladding Panels and Trim and Weather-Resistant Panel

Ref. 3/A-502

Ref. 1/A-502

CLADDING PANELS AND TRIM and WEATHER – RESISTANT PANEL:

Returning back to the view of the cross section of the middle tetrahedron and focusing on a single detail connection, the new elements of the wall system can be seen. The new wall systems consists of custom extruded aluminum trim and aluminum plank wall system. Both must match the aesthetic qualities of the original wall system, in both color and texture. Historically accurate replication of the aluminum rainscreen elements visible on the exterior will be paramount to the success of this project. Construction of the cladding panels and trim will require careful coordination with the SHPO Section 106 consulting parties and the Academy.

A weather resistant panel will be behind the aluminum panels. This panel system will contain insulation sealed within. One the panel has been installed, sealant will be installed along the edges to make the panel watertight. Custom extruded pipe sleeves will connect the panels to the existing structural steel frame.

Plaster, Speakers, and Lighting

Ref. 1/A-501

Ref. 3/A-202

The project will replace all lighting and controls in the protestant chapel exterior walls, at the interior and exterior. Only the lighting in the protestant level walls is being replaced; all other lighting is to remain.

Existing Steel Structure

Ref. 1/A-502 Existing Structural Steel

The existing structural steel will remain in its entirety. The steel is covered in its entirety in lead based paint, but no welding will disturb the paint. Intumescent paint must be applied on the entire steel system for fire protection.

Exterior Envelope – End Walls

Ref. 2/A-202

GLAZING:

Replace all glazing and aluminum storefront system with blast resistant glazing, retaining the existing steel structure.

DOORS AND METAL PANELS:

Restore the doors, hardware, and metal panels at the south entry to Protestant chapel. Very limited door repair and cac reader installation at one Catholic Level entrance as well.

(2/A-202) blow up

Fire Protection Current Scope:

Replace Fire Alarm System Install Mass Notification System Apply intumescent paint to structural steel Remainder of Scope to be finalized prior to DEC 17:

Modifications to some existing stairs Construction of fire-rated vestibule in the Catholic level Limited fire suppression

The project will replace all lighting and controls in the walls, both exterior and interior. Only the lighting in the protestant level walls is being replaced; all other lighting is to remain.

Pew and Organ Restoration

Pending Design Construction of performance testing mockup

Fabrication of aesthetic samples of aluminum panels and trim

Scoping investigation for organs and pews

Finalization of fire protection design

Replacement of speaker system

To assure performance characteristics and reduce risk of construability and performance issues, the Air Force in conjunction with AECOM and WJE are producing a full-scale mockup of the envelope design solution. This mockup will be tested for water and air intrusion, to validate performance. The mockup is also intended to validate constructability, and any encountered challenges will be addressed prior to release of the final design package.

In addition, a project to fabricate and anodize samples of the aluminum cladding and trim is currently underway. These samples will be made available to the awarded Contractor, as an aesthetic benchmark.

CTR Name is performing an investigation of both organs to define the restoration scope for the project; Pew restoration scope is also currently being finalized

Some additional fire protection design elements not currently shown in the Draft Final design submittal may be included in the final design submittal

The Draft Final design submittal shows reinstallation of the existing speaker system, but the final design submittal may include full replacement of that system.
