While the project SOW identifies AFMAN 32-1076 as an applicable design standard, UFC 3- 535-01, which took effect on 17 November 2005, supersedes the AFMAN 32-1076 as identified within UFC 3-535-01. The airfield lighting system design is based upon the criteria of UFC 3- 535-01 and where criteria is not identified, the FAA design standards are followed.

1.3 Key Findings

The airfield lighting distribution system is in critical need of repair. The current light layout does not comply with the requirements of UFC 3-535-01, Visual Air Navigation Facilities and the power supply cable insulation and conduit has degraded to the point that a major failure could occur at any time. To repair the current system and bring the airfield lighting within currents standards will require a review and evaluation of the entire airfield lighting system and design of a full replacement.

The existing underground ductbank system throughout the airfield is considered unsuitable for continued use, because the cost of repair exceeds the cost of replacement. The conditions of the conduits have been reported to be collapsed in multiple locations and existing airfield lighting cables cannot be removed without extensive effort. With that, the majority of the existing cable and conduit network may be abandoned in place due to the high cost of removal.

Replacement airfield lighting system will include new fixtures and new power circuits which shall terminate at the existing airfield lighting vault. The existing airfield lighting electrical vault equipment will be replaced with new, switchgear style, constant current regulators. The existing copper control wiring for the Runway 08 approach lighting system (ALSF-1) will be replaced with fiber optic cable to enable control from airfield lighting vault.

Both existing PAPI systems, located at each runway end (08 & 26), have exceeded their useful life and will be replaced with new systems powered from the airfield lighting vault.

The existing Runway 08 ALSF-1 fixtures appear to be in a functional condition. The existing RW 08 ALSF-1 lights will be converted from a 2/3 circuit system to a 4 circuit system. The existing conductors will be replaced with new conductors. The existing underground ducts will be reused. The existing medium voltage electrical service will be replaced with a MV feeder from the airfield lighting vault to the flasher system component of the Runway 08

ALSF-1.

2.0 Project Specifics

2.1 Layout

A new airfield lighting system with new runway and taxiway lights will replace the old system.

The old light fixtures above ground will be removed and capped as necessary to facilitate the installation of the new fixtures, but the distribution system below ground may remain due to difficulty and cost to remove. The existing lights are at non-standard and irregular spacing and offsets. The new replacement lights will be installed based on the latest design and installation standards. The existing airfield signs were recently replaced with LED type signs and therefore will remain. New conduit and cabling will be installed for the existing airfield signs. The airfield signage map and overall layout was reviewed for compliance with current standards. The airfield signs meet current standards, but it is recommended that the A/C rinse exit sign be moved to the other side, and add an ILS hold sign at taxiway F.

The Runway 08 threshold lights are not currently located in the standard location.

Replacement threshold and runway end light fixtures will be installed in the appropriate location, based on the current standards. L-868 load-bearing type light cans will be installed with heavy duty lids to allow for future semi-flush fixtures to be installed.

2.2 Power

The power for the lighting system will be supplied from equipment in the existing Airfield Electrical Vault (AEV). New duct bank is planned for installation nearly parallel to the existing duct bank primarily along the north side of the aircraft apron and along the edges of the Runway and Taxiways. The edge lights and airfield signs will be powered through constant current regulators that provide 6.6 Amps of current at the highest setting. All new circuits will be installed using FAA L-824 #8 AWG, Type C, 5000 V class cable.

The sequenced flashing lights on the Runway 08 ALSF-1 require a low voltage 120/240 V power source. Due to the distance from the AEV, the power will be brought to the flasher controller at 2,400 V and transformed down to 120/240, via a step-down transformer adjacent to the existing master control unit.

2.3 Duct Bank

The primary duct bank for the existing Runway 08 ALSF-1 will consist of 8 conduits. The power portion of the duct bank will contain (6)-2” conduits for the four (4) constant current circuits, one for the sequenced flasher power circuit, and one spare. The communications portion of the duct bank will contain (2)-2” conduits, one for the signal cable and one spare.

The duct bank for the other airfield lighting systems will consist of a variety of conduits, based on the required number of circuits within a particular run. Efforts will be made to minimize the

Circuit, Lights, and PAPI Systems, F.2375/2380 JBLE-Langley

100% Design Submittal 21 October 2016 number of runs from each area of the airfield to the vault in order to create a safer and more maintainable condition. Each circuit will be installed in a separate conduit and the pullcan plaza type junction structures will be utilized. Spacing of 12” between the power and signal conduits will be maintained throughout the entire duct bank run.

The Contractor will be directed to coordinate the location of the duct bank and pull can plazas with the Base Civil Engineer. This will be especially critical in areas where the new duct bank crosses below or above the existing airfield electrical power.

The duct bank will generally be the US Air Force standard configuration. However, if there are portions that may be constrained by the depth of excavation, those portions of duct bank will require a special design in which the conduits may be laid horizontally instead of stacked. The depth of this portion of the duct bank may be non-standard. If that is the case, due to the shallow burial, the entire length of this duct bank would be concrete encased. Directional boring was discussed with Langley AFB. Langley AFB preferred directional boring too the greatest extent possible on the airfield. Directional boring will be permitted as an option to trench and backfill, except that directional boring will be provided exclusively under pavements.

The duct bank crosses under pavement in several areas. Directional boring is recommended for all pavement crossings. Similarly, spare ducts will be proposed at each pavement crossing.

2.4 Signal

The Runway 08 sequenced flashing light Master Controller located adjacent ALS station 17, near the perimeter road along the Runway 08 ALSF-1 light towers shelter requires a fiber optic signal cable from the Airfield Lighting Control System (ALCS). This signal cable will be replaced with a fiber optic cable with connections to the ALCS controller in the vault and the Master Flasher Controller.

2.5 Airfield Electrical Vault

Modifications to the Airfield Electrical Vault include the following:

1. Replacement of the existing stand-alone constant current regulators with switchgear style regulators, including integral insulation resistance monitors.

2. Replacement and/or modification of existing switchgear for airfield lighting power and control changes.

3. Replacement and reconfiguration of the electrical power distribution and circuitry to power the new switchgear type regulator and control systems.

Calculations for electrical modifications to the vault are further discussed in Section 3.

2.6 Airfield Lighting Control

i) Existing Airfield Lighting Control System

Based on comments from JBLE airfield operations the existing lighting control meets their needs and mission requirements. Therefore, the segmentation of the runway and taxiways will remain the same for the perspective of the tower personnel. The Airfield Lighting Control System (ALCS) will be reprogrammed to accommodate the redesign of the regulator system in the airfield electrical vault. The new airfield lighting equipment will be connected in the vault and tied to the current control system.

ii) Taxiway H

The Taxiway Hotel taxiway currently has edge lighting which is controlled by a constant current regulator at NASA. However, the USAF requires use of a portion of Taxiway Hotel in order to access the arm / de-arm pad approximately half way along the taxiway. In accordance with Langley AFB direction, the complete Hotel taxiway will be re-circuited to be connected and controlled by Langley AFB air traffic tower and airfield lighting vault. This is proposed to be accomplished by powering of the complete Taxiway Hotel from a new constant current regulator in the USAF airfield lighting vault. Taxiway Hotel will be controlled, from the USAF side, in the same way as all other airfield lighting circuits.

2.7 Airfield Impacts

Impacts to the airfield and operations in order to implement these airfield lighting systems repairs / replacements / upgrades include the following:

1. Existing runway and taxiways will require temporary closures.

2. Precision Approach Path Indicator (PAPI) lights will be out of service for a period of time.

3. A displaced threshold on Runway 08 end will be required for a portion of the work to complete the Runway 08 threshold replacement and the Runway 08 ALSF-1 work.

This may require the installation of a temporary BAK 12.

4. Current Runway 08 approach end BAK 12 may be unusable for a portion of the work.

5. The Glide Slope for Runway 08 will be inoperative during the threshold displacement. This work should not affect the use of the Runway 08 Localizer.

6. Runway 26 ILS will be unusable during work in the Localizer Critical Area.

7. Follow-on work and commissioning may require additional temporary closures.

These impacts will be mitigated by phasing and work requirements described in the phasing

3.0 Airfield Lighting Loads - Preliminary

3.1 Existing Conditions Evaluation

The existing airfield lighting systems were evaluated based upon the current conditions and reports from airfield electricians and other JBLE staff. Although a precise fixture count was not completed due to limited available information, an estimate of the number of fixtures per circuit was prepared based upon review of the available Google Earth imagery as well as information provided by JBLE staff. Although further analysis will be required as the design process continues, the preliminary load calculations provide a good representation of what is currently in place and how each of the existing circuits are loaded.

3.2 Constant Current Regulators - Existing

JBLE currently has 27 Constant Current Regulators (CCR) connected to the airfield lighting system plus unconnected spares. Airfield Operations personnel indicated the individual control and operation of each airfield circuit is adequate to meet their needs and mission requirements.

Based on preliminary calculations, most of the existing CCRs are significantly under-loaded.

This is based on raw, preliminary load calculations, not including the unknown factor of energy leakage due to old, failing, bad cable. JBLE staff reported that the majority of the cable throughout the airfield is old and the conduit duct system has collapsed or is silted in and blocked, creating extremely poor electrical continuity and maintenance conditions. Due to the under-loading of the CCRs and the fact that Air Ops does not require additional control, JBLE seems to have too many regulators.

Preliminary airfield lighting load calculations for the existing conditions can be found in the table in Attachment B of this report.

3.3 Constant Current Regulators - Proposed

With the space available and current floorplan of the existing airfield lighting vault building, switchgear style CCRs should be considered to replace the existing stand-alone style CCRs.

This will clear up the floor space, creating a cleaner and safer working environment to perform maintenance when necessary. Utilizing a switchgear style layout and providing two separate CCR lineups, JBLE can reduce the number of CCRs from 27 existing to 17, plus 3 spares. This assumes consolidating the under-loaded taxiway regulators onto 4 regulators and using circuit selector switches to divide the circuits after the regulator to provide the needed lighting controls.

The proposed CCR reconfiguration and re-circuiting can also eliminate the use of 20A circuits and utilize all 6.6A circuits.

Proposed airfield lighting load calculations can be found in the table in Attachment E of this report.

4.0 Phasing

This project involves work in active airfield operational areas to include aircraft parking aprons, taxiways, runway, and approach/departure airspace surfaces and clearance areas. Therefore, a Construction Phasing and Operational Safety Plan must be prepared and made part of the contract documents in accordance with UFC 3-260-01, Attachment B, and Section 14 and also in accordance with command and local instructions. The phasing plan has been prepared based on the designer’s experience with these types of projects and then site adapted for JBLE and its mission through meetings with air operations, security, and engineering staff and other stakeholders.

The phasing plan will be provided to the base engineering office for Operational Risk Management (ORM) review as part of the required airfield construction process. The project will require some temporary clearance area adjustments and operational restrictions to complete the project in a timely manner and minimize operational disruptions or additional hazards of extended night work or temporary relocation of aircraft. Applicable safety procedures will be followed as described in UFC 3-260-01, B14-6.7, and Special Safety Requirements during Construction. Construction excavation and trenching will take place on and adjacent to runway, taxiway, and apron edges with temporary waiver approved by installation commander.

The project phasing includes the following basic requirements:

• Coordination with tower and Air Ops at start and end of each work period.

• Traffic control and entry point control to be coordinated with security forces.

• Coordinate runway, taxiway, and apron work area closures with Air Ops/Control tower throughout each phase of construction. Appropriate airfield construction signage will be required to clearly delineate work areas.

• FOD control is critical during ongoing work and will be checked at the end of each work period before the airfield pavement is returned to active status.

4.1 Phasing Plan

Construction completed on and within 100’ of the edge of the Runway during nighttime hours of 2230 – 0600. Construction completed outside of 100’ of the edge of the Runway during normal, daytime working hours.

Runway Impacts – Closed during night work, reopened for full operation each morning at 0600.

Taxiway Impacts – Taxiways closed for duration of time work conducted along TW edge.

Eight (8) primary work areas are defined based upon minimizing operational impacts:

1.1.1. MUHJ 14-4077, Repair Runway/ Taxiway & airfield signage circuits, lights, and PAPI System, F. 2375 / 2380: The intent of this project is to repair by replacing the airfield signage lighting circuits, runway lighting circuits, taxiway lighting circuits, runway edge lights, runway end inset lights on 08 approach end, constant current regulators, and all associated controls, conductors, vaults, fixture bases, isolation transformers and conduit. Project intent also includes repair by replacement of PAPI systems and circuits on both ends of Runway 08/26 at Langley AFB, JBLE. T he scope of work for this project includes the following areas at the site that require repair:

1.1.1.1. Repair by replacing the circuits for all lighted airfield signage, runway edge lighting and all taxiway edge lighting (taxiways A, B, C, D, E, F, K and H), to include replacement of all controls, conductors, conduit, isolation transformers, constant current regulators, concrete vaults, fixture bases, and foundations. Repair by replacing all elevated runway edge lighting fixtures.

Some runway edge lighting will be required to be spaced differently to accommodate existing taxiway intersection configurations. Lighting control system and constant current regulators are required to be directly compatible with the existing airfield lighting control system. The system must be designed in accordance with guidance listed in Paragraph 1.2.5, below.

1.1.1.2. Repair by replacing existing runway threshold inset lights on runway 08 overrun and relocate new inset light bases within current approved distance from runway 08 threshold. Relocation includes construction of new overrun pavement to accommodate circuit and light base installation as well as new overrun pavement where existing light bases are to be removed.

1.1.1.3. Construct new taxiway lighting and all associated circuits, elevated fixtures, vaults, conductors, isolation transformers, conduit, constant current regulators, and foundations for taxiway J and taxiway H. New circuit shall terminate at the existing airfield lighting vault.

1.1.1.4. Repair by replacing the PAPI system and all associated circuits, conduit, and mounting bases on both ends of runway 08/26.

1.1.1.5. Repair by replacing the circuit for the Runway 08 approach lighting to include only conductors, conduit runs back to airfield lighting vault.

1.1.1.6. Design work includes all necessary site surveying and documentation in accordance with paragraph 3.8 and subparagraphs below.

1.1. DESIGN FOR USE OF RECYCLED-CONTENT PRODUCTS (GREEN PROCURE-

MENT): During the design of the project, the A-E shall incorporate in this project, as a substi-tute to non-recycled content products, recycled-content products that are listed and identified in the Environmental Protection Agency (EPA) Comprehensive Procurement Guidelines (CPG) for recycled-content products. See also SECTION 01 12 00 ENVIRONMENTAL MANAGEMENT SPECIAL CONDITIONS. The Contractor shall use recycled-content products as required by EPA and other Governmental agencies and Federal Acquisition Regulation (FAR) clauses.

Executive Order 13423, (Strengthening Federal Environmental, Energy and Transportation Man-agement) and Section 6002 of the Resource Conservation and Recovery Act (RCRA) requires that the Federal Government use recycled-content products in the construction and/or renovation of facilities. The A-E shall consider this a standard requirement for all aspects of the project de-sign.

The recycled-content products listed in the CPG can be found in the EPA website at www.epa.gov/cpg/products.htm. This list is subject to change at any time so it is the Contractor’s responsibility to be aware of any updates or additions.

Such products shall also comply with the requirements of the EPA Recovered Materials Advisory Notice (RMAN). The RMANs recommend recycled-content ranges for CPG products based on current information on commercially available recycled-content products. The recommended re-covered materials content percentage can be obtained by clicking on the product on the website.

Any exemption from the Green Procurement Program for Recovered Materials requires approval in writing from the Contracting Officer. Exemptions can only be taken if;

(1) The item is not available within a reasonable period of time.

http://www.epa.gov/cpg/products.htm

(2) The item fails to meet a performance standard in the specifications.

(3) The item is only available at an unreasonable price i.e., the recycled-content product costs more than the non-recycled content product.

(4) The item is not available from two or more sources.

Specific reasons why an exemption is taken will be specified and documentation supporting this reason will be provided and attached. These forms will be kept in the project folder indefinitely.
