4 Repair and/or Modify Facilities and Infrastructure

4.1 AIR TRAFFIC CONTROL TOWER: The ATCT Control Cab window glasses were installed at an outward angle of 6.5 degrees which produces multiple and simultaneous reflections and visual illusions on the interior of windows. Window reflections and visual illusions present a high risk to safety of flight, as the ability of air traffic controllers to view aircraft movement areas is degraded. The Contractor (KTR) shall repair and/or modify the ATCT Control Cab windows to meet the requirements of UFC 4-133-01, para 4-1.2.9. The contractor may be required to perform investigative work to determine appropriate work methods and structural modifications.

4.1.1 The contractor shall submit shop drawings for approval of new window design and all work associated with this SOW. The drawings shall include structural modifications to existing supports and framework. The contractor shall also provide method work statements prior to performing repairs.

4.1.1 Control Cab glass must extend below the controllers console. The glass must also be widen to reduce the number of intermediate framework mullions (UFC 4-133-01, para. 4.1.2.10). The glass must be low-iron glass to optimize visible light transmittance. Tinted glass or heat strengthened glass must not be used for the cab glass. Low-E coated glass may be used with the understanding that the coating may reduce visible transmittance. Coordination with HVAC design must take place during planning and design phases to determine the acceptable heat transmission for the low-E coated glass.

4.1.2 Control Cab glass must slope at an outward angle of 15 degrees from vertical (UFC 4-133-01, para. 4.1.2.9).

4.1.3 Use double pane glazing unless design conditions dictate otherwise.

4.1.4 Window units must be constructed with a metal or composite plastic perimeter or a unitized extruded aluminum system frame. The frame must be bonded to the glass to provide an airtight, waterproof, and vapor proof seal.

4.1.5 Control Cab glass must meet site-specific wind load and seismic requirements. Glass must allow light gun red, white and green light from inside the ATCT to the outside.

4.1.6 The KTR shall repair and/or modify the ATCT Control Cab window mullions to meet the requirements of UFC 4-133-01, para 4-1.2.10.

4.1.6.1 Minimize control cab window mullions in all corners and in between glass panes for maximum air traffic

C-7 controller visibility (Attachment 3). Window mullions should not be directly in the line of sight to critical aircraft movement areas such as the approach ends of the runways.

4.1.6.2 To minimize sun reflections and hindrance of night vision, cab window mullion and column finishes must be a non-reflective dark color, and must incorporate a high performance anti-corrosion protection coating. Particular attention must be paid to prevent sunlight reflections from the windowsills and mullions. Consider butt glazing in place of non-load bearing mullions.

4.1.7 The KTR shall install window sunshades in the ATCT Control Cab to meet the requirements of UFC 4-133-01, para 4-1.2.11. If the sunshades cannot be recessed due to existing conditions, the contractor shall provide alternate solution(s) for approval.

4.1.7.1 Provide manually-operated window sunshades for the ATCT Control Cab windows. Refer to FAA-E-2470b, Transparent Plastic Window Shades and FAA-ANI-300-380, Transparent Plastic Window Shades. The shades must be at least 0.125 mm thick, color smoke gray, body dyed, supported by rollers with constant tension. Follow slope of windows and match size and shape of each windows. Manual operation is preferred - electric rollers are not encouraged. “Mini-blinds” or opaque, semi opaque, or mesh type shades are prohibited.

4.1.8 The interior walls below the windows shall be lowered below the controller consoles to accommodate the new windows and provide proper viewing angle as per UFC 4-133-01, para. 4.1.2.9.

4.1.9 Exterior Catwalk. The exterior catwalk wall will require modification to provide maximum air controller visibility as shown in Attachment 3. The existing concrete parapet wall shall be cut down and a metal guardrail shall be installed.

The railing must be OSHA compliant as noted on Attachment 3. During the saw cutting of the existing concrete parapet wall, extreme caution is necessary due to its height from the ground; and to prevent concrete debris to fall down onto the taxiway. Install a heavy duty fabric or equivalent to catch the concrete debris from falling.

4.1.14 ATC Emergency Generator: All electrical power provided to ATC and Air Operations Facilities is considered “Essential”, requiring back-up by an Emergency Generator (E/G). The contractor shall provide an electrical survey and coordination study to determine the location and size (capacity) of the emergency generator in addition to all related work required to install, including Automatic Transfer Switch (ATS). This Essential power must be supplied on a split-bus system, which is herein denoted as Critical and “Non-Critical”. Equipment to be supplied from the Critical bus is limited to the ATC electronic equipment, the signal light guns, and select non-ATC computers, LAN, or other technical equipment that may be required. Non-Critical circuits include the facility mechanical and building systems, such as the HVAC, lighting, and fire protection systems. To ensure equipment operation during extended power outages, the HVAC systems serving Critical spaces must be on E/G power. If an ATCT is located adjacent to an RACF or AOB, a common emergency generator must be considered.

4.1.14.1 Emergency Generator Location: Consider an outdoor unit with a weatherproof enclosure in mild climate conditions. Where the E/G is located in a cold climate, the emergency generator must have an in block heater to facilitate rapid start-up during cold winter snaps. If the cold weather is extreme, utilize a crankcase engine lubricating oil heater to reduce the oil’s viscosity and facilitate an easier and faster start. Consider the use of a battery heat jacket in extreme frigid weather to facilitate full battery cranking power. An ether injection system for direct injection into the engine’s intake manifold will enhance starting capability during very frigid weather. Consider a below-ground generator vault for units which must be sited within airfield clear zones or primary surfaces.

4.1.14.2 Emergency Generator Fuel Storage: Design fuel storage for diesel or jet fuel powered generators in accordance with: UFC 3-460-01, Design: Petroleum Fuel Facilities, state and local regulations, and the following:

• Title 40, CFR Part 112, Oil Pollution Prevention

• Title 40, CFR Part 113, Liability Limits for Small Onshore Storage Facilities, Subpart A “Oil Storage Facilities”

C-8

Provide fuel storage capacity for a minimum of 36 hours of continuous generator operation. This will account for periodic engine testing while ensuring at least 24 hours of fuel supply for the full required load during an actual electrical emergency. Provide separation between fuel storage tanks and adjacent buildings, parking aprons and property lines in accordance with UFC 3-460-01. Provide double wall storage tanks and piping. The screen wall surrounding an exterior fuel storage tank must be at least 6 inches (150 mm) taller than the tank. Underground fuel storage tanks are not allowed for ATC Facilities.

4.1.14.3 Joint Seals: Install joint seals between rigid (concrete) and flexible (asphalt) pavements along Taxiway Delta/Aircraft Parking stands and covered parking shades. Refer to UFC 3-260-02, Figure 12-35, Rigid-Flexible Pavement Junction. Contractor to field verify the actual location and linear measurement of the joint seal to be installed.

4.1.14.4 Spall Repairs: Repair concrete edge spall IAW Industry Best Practices: Use UFGS for guidance. Also, requires submittal for repair material, which meets the Tri-Service Runway Pavement Criteria;
