[U.S. FEDERAL AVIATION ADMINISTRATION (FAA)FAA AC 150/5300-13(Basic; Changes 1 thru 12) Airport DesignFAA AC 70/7460-1(Rev K) Obstruction Marking and Lighting]1.2 DEFINITIONS
1.2.1 Landing Areas
"Landing Areas" means:
a. The primary surfaces, comprising the surface of the runway, runway shoulders, and lateral
safety zones. The length of each primary surface is the same as the runway length. The width
of each primary surface is 609.6 meters 2000 feet (304.8 meters 1000 feet on each side of the
runway centerline). [Exceptions: Some airfields are based on a primary width of 457.2 meters
1500 feet (228.6 meters 750 feet on each side of the runway centerline). In such instances,
substitute the proper width in the applicable statements.]
b. The "clear zone" beyond the ends of each runway is the extension of the primary surface
for a distance of 304.8 meters 1000 feet beyond each end of each runway.
c. All taxiways, plus the lateral clearance zones along each side for the length of the taxiways
(the outer edge of each lateral clearance zone is laterally 76.2 meters 250 feet from the far
or opposite edge of the taxiway (example: a 22.86 meters 75 foot widetaxiway must have a combined
width and lateral clearance zone of 129.54 meters 425 feet.)
d. All aircraft parking aprons, plus the area 38.1 meters 125 feet in width extending beyond
each edge all around the aprons.
1.2.2 Safety Precaution Areas
“Safety Precaution Areas” means those portions of approach-departure clearance zones and transitional zones where
placement of objects incident to contract performance might result in vertical projections at or above the approach-departure
clearance, or the transitional surface.
a. The “approach-departure clearance surface” is an extension of the primary surface and the
clear zone at each end of each runway, for a distance of 15240 meters 50,000 feet, first along
an inclined (glide angle) and then along a horizontal plane, both flaring symmetrically about
the runway centerline extended.
(1) The inclined plane (glide angle) begins in the clear zone 61 meters 200 feet past the end
of the runway (and primary surface) at the same elevation as the end of the runway. It continues
upward at a slope of 50:1 (0.305 meters 1 foot vertically for each 15.24 meters 50 feet horizontally)
to an elevation of 152.4 meters 500 feet above the established airfield elevation. At that
point the plane becomes horizontal, continuing at that same uniform elevation to a point 15240
meters 50,000 feet longitudinally from the beginning of the inclined plane (glide angle) and
ending there.
(2) The width of the surface at the beginning of the inclined plane (glide angle) is the same
as the width of the clear zone. It then flares uniformly, reaching the maximum width of 4876.8
meters 16,000 feetat the end.
b. The “approach-departure clearance zone” is the ground area under the approach-departure
clearance surface.
c. The “transitional surface” is a sideways extension of all primary surfaces, clear zones,
and approach-departure clearance surfaces along inclined planes.
(1) The inclined plane in each case begins at the edge of the surface.
(2) The slope of the incline plane is 7:1 (.305 meters 1 foot vertically for each 2.13 meters
7 feet horizontally). It continues to the point of intersection with the —
(a) Inner horizontal surface (which is the horizontal plane 45.72 meters 150 feet above the
established airfield elevation); or
(b) Outer horizontal surface (which is the horizontal plane 152.4 meters 500 feet above the
established airfield elevation), whichever is applicable.
d. The “transitional zone” is the ground area under the transitional surface. (It adjoins
the primary surface, clear zone, and approach-departure clearance zone.)
1.3 SUBMITTALS
NOTE: Review Submittal Description (SD) definitions in Section 01 33 00 SUBMITTAL
PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are [for Contractor Quality Control approval.][for information only. When used, a designation following the
"G" designation identifies the office that will review the submittal for the Government.] Submit the following

]][3.3 MODEL UNIT
NOTE: Use the following paragraphs on projects with repetitious unit construction.
Require the Contractor to complete a model unit to various levels, and have
the materials and workmanship approved prior to proceeding with the remainder
of the project. Examples of such projects are BEQ's, BOQ's, and family housing
units, both renovations and new construction.
Prior to placement of material orders for components of the [BEQ living suites][BOQ living suites][family housing
units][_____] and the installation of those components throughout the project, the Contractor mustcomplete the
construction of the components of the model unit, and gain the approval of the Contracting Officer for the materials
and workmanship therein.
NOTE: Edit the following paragraph to describe the extents of the model unit(s),
and delineate whether each is a housing unit building, or a multiple resident
living unit within a multi-unit building.
NOTE: Choose housing unit and the last bracketed option in the paragraph for
family housing projects.
3.3.1 Model Unit Description
Provide a model unit made up of enough [living suites consisting of two bedrooms and an interconnecting bathroom][single
family housing units][_____] to show all of the different levels of completion required below. [The model unit
must have enough [suites][housing units] to show all level of completion simultaneously[, except for foundation
and floor slab levels which are approved by the Contracting Officer and covered by following levels].] The model
unit must be [living suites][family housing units][_____] constructed at the location agreed upon with the Contracting
Officer and [a part of the permanent structure as indicated] [a temporary structure constructed to full scale
at the location indicated, and demolished at the completion of the contract].
3.3.2 Model Unit Requirements
Adhere to the following requirements for model construction:
a. Provide materials in model unit identical to those actually approved in submittals. The
QC Manager and Organization must be in place to approve and process submittals in accordance
with Section 01 33 00 SUBMITTAL PROCEDURES. Do not procure, fabricate, or install materials
prior to approval by the Contracting Officer.
b. The Contracting Officer retains the right to disapprove and reject materials or items which
are not in compliance with the project drawings and specifications.
c. After approval of initial product submittals, provide full size samples of these components
in the required color, and in sufficient quantity to completely outfit the model unit. Provide
full size samples as dictated by the construction schedule for installation of those components
in the model unit. Do not order or approve production of any materials beyond those required
for the model unit, until the full size samples have been installed in the model unit and approved
by the Contracting Officer.
d. Proceed immediately with construction of the model unit after the Contracting Officer acknowledges
the required product submittals are approved.
e. Provide all temporary utilities and climate control necessary to construct, inspect, approve,
and maintain the model unit.
f. Provide and maintain the following throughout the construction period of the entire project:
Temporary parking at the model unit; signage from the temporary parking to the model unit; the
visual approach to the unit including trash removal, lawn [and landscaping ]maintenance.
g. Locate the model unit in an easily accessible location for public tours. The Government
retains the right to use the model unit for supervised tours and public relations activities
following each level of completion. Tours will take place during normal working hours.
[h. Prior to completion and approval of the model unit, and with written permission to start
from the Contracting Officer, the Contractor may perform general sitework and run major utility
lines for the rest of the project.]
NOTE: Include the next item when construction time is limited. Confirm with
Contracting Officer and Activity User that they can consistently inspect and
approve the model unit's different levels of completion before adding this option.
[i. As each model unit's level of completion is approved by the Contracting Officer, construction
of that level's components throughout the remainder of the project may proceed.]
3.3.3 Model Unit Levels of Completion
NOTE: Choose one of the three model unit completion paragraphs below and confirm
the selection with the Using Activity and Contracting Officer. The first bracketed
option requiring the model unit to be complete before starting the construction
of the facilities should only be used when delivery time of the facility is
not critical. This option will delay the construction of the facility(s) until
the model unit is constructed and approved. The second bracketed option using
two levels of completion is most effective on BEQ construction but can be used
on housing. The third bracketed option using multiple levels of completion
should be used when time is a critical issue, especially on housing. This option
sets incremental approval of multiple levels allowing contractor to proceed
quickly into the construction of the facility(s). In the third option verify
with the Contracting Officer the number of approval stages needed. In this
option, levels may be combined if confirmed with Contracting Officer.
[The completed model unit must be exhibited for approval. Upon completion, the model unit must be available to
the Government for a period of fifteen (15) working days for inspection after notification is received by Contracting
Officer.]
[Exhibit and secure approval of model unit at the following levels of completion:
a. Level 1 (Pre-Finished Level) - Model unit construction within a completed building exterior
