Part II – Design Narrative

SHELL

At the 2nd floor control tower the aluminum-wrapped wood windows are in disrepair and do not seal properly. The windows will be replaced with new aluminum wrapped wood windows that match the current windows’ operation. The painted hollow metal door slab is also in disrepair and will be replaced with new including hardware.

The painted exterior metal stairs and catwalk at the perimeter of the control tower are in good condition but need to be repainted. The entire system will be prepped in accordance with SSPC-SPC to remove rust, loose mil scale, and dirt. Exposed bare steel will be primed and the entire assembly will be repainted.

INTERIOR

New finishes will be installed the control tower. The broadloom floor carpeting will be replaced with a more durable finish rubber floor tile. All gypsum board walls will be prepped and repainted. The room’s suspended acoustical ceiling panel (ACP) system will be replaced with new. Wall-mounted and post-mounted work counters that are attached to the walls will be replaced with new solid surface countertops with wall-mounted bracket supports.

The enclosure below the control tower is utilized for storage. The room has a 2’x2’ suspended acoustical ceiling panel (ACP) system with rolled blanketed batten insulation above that is intended to insulate the floor of the control tower above. The ACP system and insulation has sustained water damage and will be completely removed. Spray-applied closed cell insulation will be applied to the wood framed floor system above to insulate the control tower floor, and the ACP will be replaced.

Design Approach

Power Systems Power is provided to Buildings 840 and 844 by a single 400A, 208Y/120V underground service. The service enters a 400A service disconnect on the exterior south wall of Building 844 via a 4” conduit and then is distributed through one electric meters (number 01881181 for Building 840). There is a 4” conduit between the service disconnect and the 840 meter and a 4” conduit between the 840 meter and an unnamed 400A panel (200A main circuit breaker) also mounted on the exterior south wall of Building 844.

This 400A panel feeds an unnamed 100A panel (100A main circuit breaker) inside Building 844 via a

100A, 3-phase circuit breaker and another utility meter (number 01683943 for Building 844). There is a 1” conduit between the 400A panel and the 844 meter and another 1” conduit between the 844 meter and unnamed 100A panel inside Building 844.

The existing service and meter equipment will remain as-is. Both buildings unnamed panels will be replaced one-for-one with new panels (1DNL1 for Building 840 and 1RNL1 for Building 844) at the existing locations utilizing existing incoming electrical feeders. The new panels will generally mirror that of existing, with the exception of additional circuit breakers required for revised or added equipment and with spare circuit breaker capacity. New branch circuits will be provided to the new mechanical equipment.

Existing power receptacles will be replaced with new power receptacles in Building B44.

Lighting Wall mounted HID fixtures provide site lighting around the perimeter of building 844 and will be replaced with LED fixtures equipped with an integral photocell.

Existing lighting in Building 844 consists of the original 2x4’ T12 fluorescent troffers and a round surface mounted fixture. Lighting controls are limited to local switches.

Original lighting will be replaced with new to meet the uniformity and luminance criteria in accordance with

UFC 3-530-01 requirements. Building 844 control room lighting will consist of 2’x4’ LED flat panel troffers in conjunction with a 0-10V dimmer switch, ceiling mounted occupancy sensor and ceiling mounted daylight sensor. Building 844 storage room lighting will consist of 2’x4’ LED flat panel troffers in conjunction with a wall sensor/switch combination device.

Existing (4) pole mounted fixtures, poles and concrete base serving illuminance for the mockup will be removed and replace entirely with new LED floodlights, pole and concrete base. Existing branch circuits will remain and be re-used to serve the new pole mounted fixtures. All other existing pole mounted fixtures will remain as is and will be reconnected to the new power panel.

Lightning Protection A UL Master Label system in accordance with NFPA 780 and AFI 32 1065 criteria, using components manufactured in accordance with UL 96 will be added. The lightning protection system will require an LPS inspection prior to acceptance by a third-party inspector.

Technology Systems The telecommunications outlets within control building will be replaced.

Public address system with an exterior speaker will be provided at Building 844.

SPECIAL CONSTRUCTION AND DEMOLITION

Considering the age of the existing facility, the components, and the environment that the facility operates within, major upgrades and repairs to the existing fuselage mockup and surrounding burners (burn pit), electrical system, LPG propane system, in both liquid and vapor states, water system and controls are required to bring the facility up to current operating standards to move the facility closer to meeting requirements of a standard United Stated Air Force Crash Fire Rescue Training system. It is the goal of the end user to upgrade and modify the facility to achieve continuous successful training for the next 15-

25 years.

Two new concrete vault and two utility trenches along both sides of the aircraft mock-up. The new concrete vaults will be constructed at the perimeter of the burn pit, and will provide space for the electrical controls, water distribution manifold, and propane distribution controls. The vault and trenches will be constructed flush with the existing grade, with steel lids capable of supporting the weight of firefighters

(foot traffic only).

Electrical

The revamped electrical system will include a pilot box ignition system to provide improved control, ignition, and breadth of options for fire simulations. This new system will be NFPA 1402 (2019 edition) compliant. The direct spark system used in the existing system will be removed.

Remove the electrical components that are underneath the existing airframe mockup in their entirety.

Install a concrete vault (flush with the ground) with aluminum hatch at the edge of the existing burn pit.

The concrete vault will be positioned so that heavy traffic is not applied to the vault and will be further protected with curbing. Install new control wiring and power from the existing control tower to the proposed vault. The vault shall house in its own transformer cabinet to generate 10,000 volts to igniters at 14 burn locations.

Distribute Ignition Cable in accordance with the Technical Order from the transformers to the new ignition locations utilizing HDPE conduit. Ends of conduit should be sealed around each ignition cable and thread sealant suitable for continuous submersion should be installed. Ignition locations include the following:

i. Starboard Front and Rear Fuel Spill Fires

ii. Starboard Wheel/Brake Fire

iii. Starboard Engine Fire

iv. Port Front and Rear Fuel Spill Fires

v. Port Wheel/Brake Fire

vi. Port Engine Fire

vii. Port Engine 3D Spill Fire

viii. Tail Engine Fire

ix. APU Fire

x. Interior Burners at Cockpit, PAX and Cargo Burners

All new igniters for ground burners and new water jacket assemblies for the above ground burners will be provided.

Three-phase power will be provided to run the circulation pump at the retaining pond.

The electrical system will be modified so that proper grounding is applied to the modified system. Proper lightning protection for the mockup, the structure, and other components of the fire training system will be provided.

Controls

Replace the PLC system. The existing condition of all control wire is unknown. To simplify the system and for ease of troubleshooting, a complete rewire is recommended. The fires will be controlled from an interactive touch control system (minimum size is 20”). All operations will be capable of being controlled from the tower.

Water System

The water system upgrades will include new connections into the existing water supply line and running it into a new concrete vault that will house a water distribution manifold. This manifold will supply the following functions:

i. Airframe Mockup Cooling

ii. Supply to Water Jackets, with a new water jacket system

iii. Supply to Fireplaces as required – including option of filling burn pit area if full grating is requested.

The vault will slope to a low point drain to remove any water which might accumulate in the vault. Piping configurations and placement should be installed with consideration taken to the simplicity of winterizing the facility and draining all employed water lines.

Liquid Propane Gas (LPG) System

All existing propane piping inside the burn pit and underneath the existing airframe mockup will be removed. The existing liquid propane gas line running to the burn pit will be connected to the concrete vault. An LPG distribution manifold will be installed in the vault that has the capability to control propane flow to the 14 individual burn locations from the control tower. The distribution manifold shall have the equipment and controls to adjust fire sizes to an adequate size for the end user. All valves, equipment and components shall be installed so that access and repair/replacement actions are performed with minimum effort.

Stainless steel fireplaces shall be manufactured and installed to hold water and support piping, and necessary valve configuration for immediate emergency stop activities. Fireplaces shall also be able to be drained of water with minimal effort for winterization purposes.

All existing valves and equipment at the fuel tank farm from the tank to the vaporizer will be replaced.

Airframe Mockup Modifications

The existing plate steel and vault shall be removed from below the airframe mockup so that the airframe has a more realistic look to it. Structural steel shall remain in place as required to maintain the integrity of the airframe mockup. All minor weld repair work shall be performed on the existing mockup by method of gouging and welding in accordance with AWS D1.1.

Burn Pit Modifications

Remodel the burn pit so metal grating can cover most of the burn pit area. These modifications will allow inspection, maintenance and repair of utility lines to be accomplished quickly and efficiently. The current burn pit follows the AFCEC model of liner covered by sand, with a top course of crushed stone aggregate.

This aggregate is held in place by moveable concrete parking barriers.

A number of modifications would be required to add a concrete base to the burn pit. Complete removal of all aggregate from within and around the existing burn pit is required. The existing burn pit sand and liner would be removed. A new 6” thick reinforced concrete slab would be placed over liner. An 8” high concrete curb would be added at the perimeter of the slab to create an area to allow a water pool volume to be utilized during training evolutions. A new drain system would need to be added so that the water level can be controlled to a certain training water pool elevation as well as completely drained from the burn pit area.

Structure within the burn pit area must be installed so that a metal grating surface could be constructed at the proper elevations. The metal grating surface would serve the purpose of foot traffic for fire-fighting evolutions and also provide maintenance technicians with the ability to perform visual utility inspections and service and maintenance duties.

Smoke Generation

Smoke generation capabilities should be included in the airframe mockup for high volume smoke scenarios. The smoke shall have no health hazard to trainees or instructors. The smoke generation should be safe at the operating temperatures within the training areas and should be independently selectable for the purpose of obscuration and for search and rescue and firefighter training.

Closed Circuit Television Cameras

A new camera system will be installed for real time live viewing in the control room, as well as recording and playing back of the exercise during debrief. The camera system shall consist of 2 sets of CCTV and thermal image cameras. The exterior cameras should have pan/tilt mechanism and a monitor shall be placed in the Control Room for viewing. The exterior camera should be pole mounted to the rear of the aircraft to assist in operator visual assistance for blind spot areas. The interior fuselage cameras should be positioned for a clear viewing of training scenarios and installed to accept the environment of typical fire training evolution environments. New conduits and wiring will be included.

BUILDING SITEWORK

In addition to the proposed burn pit modifications, a new radial concrete slab will be poured around the perimeter, extending 20 feet out. Any additional site work performed as a part of this project will only be to repair areas disturbed by the construction of the new fire training systems, piping, and other in-ground appurtenances associated with the burn pit.
