1. BACKGROUND

Tuskegee Airmen National Historic Site (TUAI) is a unit of the National Park Service and is head quartered at 1616 Chappie James Ave. Tuskegee, AL. 36083 There are a total of 7 buildings and 2 hangers. The Hangar#2 is one of those buildings that has a Control Tower Observation Deck and Fire Escape that is emergency need of Rehab. The Historic Tuskegee Airmen Control Tower Observation Deck and Fire Escape needs repair due to the observation deck floor and fire escape has went through decay/ rotten and needs repair/rehabbed. The Tuskegee Airmen Control Tower at Moton Field observation deck floor is also leaking and requires repair. The fire escape system is constructed of wood material and includes two balconies and a ladder.

2. OBJECTIVES:

From Moton Field’s Control Tower, controllers directed flight operations and signaled landing instructions to pilots through a system of flashing colored lights. Dispatchers called cadets for their flights. The tower overlooked the busy – and noisy

– flow of aircraft, pedestrian, and vehicle traffic between two hangars.

The tower was where the dispatcher would look out on the field and call the cadets over the loudspeaker to tell them about their flight assignments. Also in that tower was a big chamber in which parachutes were hung to dry.

The four-story, brick masonry Control Tower stood at Hangar No. 2 northeast corner and was constructed in 1942. The original Hangar No. 2 burned in 1989 and was demolished. A replica of Hangar No. 2 was built in 2010. The control tower was restored during the 2010 construction project. The structures were reopened to the public in 2014.

The observation deck floor is leaking and requires repair. The fire escape system is constructed of wood material and includes two balconies and a ladder that are anchored to the Control Tower with ¾” steel anchors. The fire escape has extensive rotten and will need to be completely replaced.

PROJECT PLANNING

An historical repair contractor will be needed to be appropriate for the project. All necessary tools, equipment and materials will be assembled and transported to a designated on-site staging area. This includes project pre-planning, the procurement of required materials, and an allowance for travel time for the crew from their respective shop facility to the project site.

A safety/hazard analysis will be conducted as part of this first task and will be supported with the preparation of a Safety Plan for all on-site activities that will be provided to TUAI prior to the beginning of the project. A pre-project safety briefing with project related personnel will occur.

Construction safety fencing will be installed around the defined work area as determined during project pre-planning. Parking, access, and egress areas will be established. Safety related signage will be posted.

Existing conditions, ongoing work, and completed preservation work will be documented through a combination of digital color photography, field sketches, and written narratives to include the timely submittal of Weekly Field Reports. Existing conditions will be documented prior to, and during project work. During project execution, representative samples of historic materials will be salvaged, inventoried, and tagged. The samples will be turned over to TUAI after the final inspection.

SCOPE OF WORK

The historical repair contractor will need a team of preservation specialists for the work identified in the following tasks. All preservation work and practices performed will comply with the Secretary of the Interior’s Standards for Historic Preservation. All salvageable fabric will be stabilized and reused whenever possible, with existing condition, initial design, and long-term maintenance in mind.

Task #1: Repair Control Tower Observation Deck

The historical repair contractor will clean the observation deck floor surface and inspect cracks and possible leaks. Any deficiencies found during visual inspection will be repaired by layering elastomeric roofing to seal the deficiencies. After the recommended cure time has elapsed, the crew will check and correct the grade of the deck surface to ensure flow to the scupper located in the southwest corner of the control tower observation deck by layering elastomeric roofing to fill the lows and creating proper flow. After recommended cure time, the entire deck surface will be coated with an elastomeric roofing system. The team will clean the concrete parapet cap with D2 and rinse with light pressure washing. The concrete parapet cap will then be sealed with an approved sealer to protect the cap and prevent water intrusion.

Task #2: Replace the Fire Escape

The historical repair contractor will remove and document the dimensions and design of the existing fire escape. The fire escape system includes two balconies and a ladder, constructed of nominal size, pressure treated, wood materials. The fire escape balconies and ladder will be constructed with kind materials matching the existing structure and dimensions. The balconies will be anchored to the structure with 4x4’s via existing ¾” anchor studs. The framework will be constructed with 4x4’s and flooring with 2x4’s. The railing will be crafted from 2x2 spindles with a 1” trim board on the interior top and bottom and the exterior top and bottom. A 2x6 outside band will be constructed to match the existing trim. The top rail will be a 4x6 with beveled edges. The ladder will be constructed with approved pressure treated lumber. The rails will be 4x4’s anchored to the wall via existing ¾” anchor studs at 2’ on center. The ladder rungs will be 2x4’s anchored to the 4x4’s at 12” on center. All lumber will be primed with a park approved primer and painted with an exterior grade latex paint.
