AIRFIELD LIGHTING VAULTS (ALV). The main ALV should contain
power supply and distribution and control equipment for runway and taxiway light
systems and other lighting circuits that can feasibly use the vault. The approach light
ALV houses power supply and controls primarily for the approach lights and sequence
flashers, but other nearby lighting systems may use the vault as an equipment shelter.
Vaults should be of concrete or masonry construction.
PAVEMENT MARKING. There are three types of runway pavement
marking: basic (or visual), non-precision instrument, and precision instrument.
Runways, taxiways, aprons, and pads all require pavement markings in conformance
with the references in paragraph 3-2.8. When a portion of a runway is constructed, or
reconstructed, the entire runway should be remarked. This may require rubber removal.
The limits of marking and rubber removal should be stated in the RFP.
OBSTRUCTION SURVEYS. The D-B Contractor should be required to
submit the results of an obstruction survey for any project involving a new runway,
runway extension, or any changes in existing runway imaginary surfaces. Also, surveys
and profiles should be submitted for any visual or electronic NAVAID for runway
approaches. Surveys and profiles should provide information in conformance with these
Obstruction surveys: UFC 3-260-01, Section 3.15.
Clear zone profiles: UFC 3-260-01, Section 3.15.
Light plane profile and light elevations for approach lights: UFC 3-535-
01, Chapter 3.
PAPI Profile showing the approach path, clearance plane, and
controlling obstruction: UFC 3-535-01, Chapter 3.
ILS glide slope Profiles showing the glide path, inner slope, outer
slope, and obstruction clearance: FAA Order 6750.16C, Siting Criteria
for Instrument Landing Systems.
The D-B Contractor should submit the results of any obstruction surveys, with
obstructions identified, with the first design submittal. The contracting officer will
determine the resolution of any obstruction.
AIRCRAFT ARRESTING SYSTEMS. Runway construction,
reconstruction, or overlay may require the installation, modification, relocation, or
upgrading of aircraft arresting systems. UFC 3-260-01 lists nine different types of
arresting systems in use today. The 35E8-series technical orders (operational and
maintenance instructions) provide information on each type of system, with installation
instructions in Chapter 3. The Government will furnish the main equipment elements for
aircraft arresting gear installation or modification.
The RFP preparer should include a narrative description of the required aircraft
arresting system work in UFGS Section 01016, Detailed Technical Requirements for
Airfield Design-Build, including:
