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 2000 feet ( 1000 feet on each side of the runway centerline).

b. The "clear zone" beyond the ends of each runway is the extension of the primary surface for a distance of 3000 feet in length for fixed wing aircraft and 400 feet in length for helicopter only runways 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 250 feet from the far or opposite edge of the taxiway (example: a 75 foot wide taxiway must have a combined width and lateral clearance zone of 425 feet .)

d. All aircraft parking aprons, plus the area 125 feet in width extending beyond each edge around the aprons.

SECTION 01 35 13 Page 1

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 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 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 ( one foot vertically for each 50 feet horizontally) to an elevation of 500 feet above the established airfield elevation. At that point the plane becomes horizontal, continuing at that same uniform elevation to a point 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 16,000 feet at 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 ( one foot vertically for each 7 feet horizontally). It continues to the point of intersection with the:

(a) Inner horizontal surface (which is the horizontal plane 150 feet above the established airfield elevation); or

(b) Outer horizontal surface (which is the horizontal plane 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.)

1.2.3 Federal Aviation Administration (FAA) Notice of Proposed Construction or Alteration

a. FAA Notice of Proposed Construction or Alteration may be required in accordance with 49 USC 44718 and 14 CFR 77 , depending on height of construction equipment on site, height of temporary structures, proximity to an airport or heliport, and specific location of

SECTION 01 35 13 Page 2 equipment or temporary structure. For the purpose of notifying the FAA, proximity shall be defined as within 5 nautical miles of a Government or civilian airfield, including landing areas, taxiways, runways and helicopter pads.

b. In order to determine if a FAA Notice of Proposed Construction or Alteration is required, refer to 14 CFR 77 Subpart B. Alternately, utilize the FAA's Notice Criteria Tool located at:

https://oeaaa.faa.gov/oeaaa/external/portal.jsp . The FAA will determine if the equipment or temporary structure exceeds obstruction standards and may pose a hazard to air navigation.

c. Failure to comply with the provisions of 14 CFR 77 are subject to Civil Penalty under Section 902 of the Federal Aviation Act of 1958, as amended and pursuant to 49 USC 46301 Subpart (a).

3.1.1 Work in Proximity to Landing Areas

Place nothing upon the landing area or applicable portions of safety precaution areas without authority of the Contracting Officer.

Use of landing areas for purposes other than aircraft operation, is prohibited without permission of the Contracting Officer, and the landing area is closed by order of the Contracting Officer and marked as indicated herein.

SECTION 01 35 13 Page 3

Accomplish all construction work on the taxiways, and parking aprons and 75 feet to each side of the taxiways with extreme care regarding the operation of aircraft. Cooperate closely, and coordinate with the Operations Officer and the Contracting Officer. Park equipment in an area designated by the Contracting Officer. Parking of equipment, vehicles, or any storage features overnight or for any extended period of time in the proximity of the landing areas or taxiways is strictly prohibited. Leave no material in areas where extreme care is to be taken regarding the operation of aircraft.

During periods of active performance of work on the airfield by the Contractor, govern all operations of mobile equipment in accordance with the safety provisions.

3.1.2 Contractor FAA Notification

When required in accordance with 49 USC 44718 and 14 CFR 77 , submit FAA Form 7460-1 and attachments directly to the FAA a minimum of 60 calendar days prior to the start date of the operations that may affect air traffic. Submit supplemental notification FAA Form 7460-2 to the FAA within 48 hours prior to start of the construction. Simultaneous with submission to the FAA, submit both forms to the Contracting Officer for information. It is the Contractor's responsibility to notify the FAA when required.

3.1.3 Schedule of Work/Aircraft Operating Schedules

Schedule work to conform to aircraft operating schedules. The Government will exert every effort to schedule aircraft operations so as to permit the maximum amount of time for the Contractor's activities; however, in the event of emergency, intense operational demands, adverse wind conditions, and other such unforeseen difficulties, the Contractor must cease operations at the specified locations in the aircraft operational area for the safety of the Contractor and military personnel and Government property. Submit a schedule of the work to the Contracting Officer describing the work to be accomplished; the location of the work, noting distances from the ends of landing areas, taxiways and buildings and other structures as necessary; and dates and hours during which the work is to be accomplished. Keep the approved schedule of work current, and notify the Contracting Officer of changes prior to beginning each day's work.

Where flying is controlled, obtain permission from the control tower operator to enter a landing area unless such area is marked as hazardous to aircraft.

3.1.3.1 Construction Operations Plan

Submit a Construction Operations Plan prior to the start of work that includes a description of the airfield work to be accomplished; the exact location of the work, noting distances from the ends of landing areas, taxiways and buildings and other structures as necessary; and dates and hours during which the work is to be accomplished. Keep the approved schedule of work current and notify the Contracting Officer of changes prior to beginning each day's work.

3.1.3.2 Existing Conditions Survey

Perform an Existing Conditions Survey and submit results to the Government

SECTION 01 35 13 Page 4 prior to the start of work. As part of this survey, inspect the work site to identify existing conditions located within the vicinity of the contract work. Utilize original as-builts if available showing possible utilities, type of pavement, thickness, airfield lighting, equipment, vehicles, structures, and parked aircraft. Unless already specified in the Contract documents, utilize the RFI process to clarify responsibility for relocating appurtenances that will interfere with work. If the site is opened up (in/under construction), update the existing survey condition to include the actual condition of the underlying conditions such as sub base, base, and pavement thickness.

3.1.4 Daytime Markings

During daylight, mark stationary and mobile equipment with international orange and white checkered flags, mark the material, and work with yellow flags.

Submit a Heavy Equipment and Vehicle List identifying all stationary and mobile equipment and vehicles that will be operating on the airfield. All equipment and vehicles must be identified by means of a flag on a staff attached to and flying above the vehicle. Flag size must be not less than 3 feet square and consist of a checkered pattern of international orange and white squares not less than one foot on each side. Flags varying in any dimension by not more than 10 percent of the specified dimensions are considered to comply with the stated requirements.

3.1.5 Nighttime Markings

During nighttime, which begins 2-hours before sundown and ends 2-hours after sunrise, mark stationary and mobile equipment and material, and work with battery-operated, low-intensity, red flasher lights. Where the Operations Officer determines that the red flasher lights may confuse pilots approaching for landings, the Operations Officer may direct that the red flasher lights be left off or that the color of the lights be changed.

Provide lighting in accordance with FAA AC 70/7460-1 . Provide a minimum of two aviation red or high intensity white obstruction lights on temporary structures (including cranes) over 100 feet above ground level.

Lights must be operational during periods of reduced visibility, darkness, and as directed by the Contracting Officer.

No separate payments will be made for lighting and protection necessitated by the safety provisions.

3.1.6 Excavation

Open only those trenches for which material is on hand and ready for placing therein. As soon as possible after the material has been placed and work approved, backfill and compact the trenches as specified.

Maintain landing areas at all times free from hazards, holes, material piles, or projecting shoulders that might damage tires or landing gear.

Keep paved surfaces clean at all times and free from small stones or other objects which could cause damage to propellers, craft, and personnel.

3.1.7 Contractor Safety Precautions

The Contractor is advised that aircraft operations will produce extremely

SECTION 01 35 13 Page 5 high noise levels and will induce vibrations in pavements, structures, and equipment in the vicinity, and may result in high velocity flying debris in the area. These anticipated hazards must be appropriately addressed in the Activity Hazard Analysis (AHA) associated with airfield work - the Activity Hazard Analysis must be in accordance with Section 01 35 26 GOVERNMENTAL SAFETY REQUIREMENTS. The Contractor is responsible for providing personal protective equipment (PPE) and other safety devices required to ensure protection of contractor personnel and equipment.

Schedule the work to eliminate hazards to personnel and equipment and to prevent damage to work performed.

Boundary areas for hazardous work locations and restrictions are defined in FAA AC 150/5300-13 . Construction activity within the limits of the boundary areas without approval of the Contracting Officer is prohibited.

3.1.8 Base Civil Engineering (BCE) Work Clearance Request

Obtain an approved BCE Work Clearance Request, AF Form 103, prior to the start of excavation, digging work, or work that disrupts aircraft or vehicular traffic flow, base utility services, fire and intrusion alarm system, or routine activities of the Activity.

1.3 SAFETY PLAN COMPLIANCE DOCUMENT (SPCD)

a. Contractor shall submit a SPCD to the Contracting Officer describing how it will comply with the requirements of the Construction Operational Safety and Phasing Plan (COSPP) and supplying any details that could not be determined before contract award. The SPCD must include a certification statement by the contractor that indicates it understands the operational safety requirements of the COSPP and it asserts it will not deviate from the approved COSPP and SPCD unless written approval is granted by the Contracting Officer. Any construction practice proposed by the contractor that does not conform to the COSPP and SPCD may impact the airfield's operational safety and will require a revision to the COSPP and SPCD and re-coordination with the Contracting Officer in advance.

b. Have available at all times copies of the COSPP and SPCD for reference by the Contracting Officer and its representatives, and by subcontractors and contractor employees.

c. Ensure that construction personnel are familiar with safety procedures and regulations on the airfield. Provide a point of contact who will coordinate an immediate response to correct any construction-related activity that may adversely affect the operational safety of the airfield. Many projects will require 24-hour coverage.

d. Identify in the SPCD the contractor's on-site employees responsible for monitoring compliance with the COSPP and SPCD during construction. At least one of these employees must be on-site whenever active construction is taking place.

e. Conduct inspections in sufficient frequency to ensure construction personnel comply with the COSPP and SPCD and that there are no altered construction activities that could create potential safety

SECTION 01 35 23 Page 1 hazards.

f. Restrict movement of construction vehicles and personnel to permitted construction areas by flagging, barricading, erecting temporary fencing, or providing escorts, as appropriate and as specified in the COSPP and SPCD.

g. Ensure that no contractor employees, employees of subcontractors or suppliers, or other persons enter any part of the air operations area (AOA) from the construction site unless authorized.

h. Ensure prompt submittal through the airfield operator of Form 7460-1, 7460-2 and NOTAMS for the purpose of conducting an aeronautical study of contractor equipment such as tall equipment (cranes, concrete pumps, other equipment), stock piles, and haul routes when different from cases previously filed by the airfield operator. The FAA encourages online submittal of forms for expediency.

i. Prior to being allowed any access to the site, the Contractor shall prepare, submit and receive approval of a Safety Plan Compliance Document.

j. The SPCD should include a general statement by the construction contractor that he/she has read and will abide by the COSPP. In addition, the SPCD must include all supplemental information that could not be included in the COSPP prior to the contract award.

k. The contractor statement should include the name of the contractor, the title of the project COSPP, the approval date of the COSPP, and a reference to any supplemental information (that is, "I , Name of Contractor , have read the Title of Project COSPP, reviewed the project drawings, read the project specifications and contract documents and will abide by it as written and with the following additions as noted:"). Generally, the format of the SPCD should follow the format of the COSPP and should also address items provided on the project drawings, specifications and contract documents pertinent to operational safety. If no supplemental information is necessary for any specific subject, the statement, "No supplemental information," should be written after the corresponding subject title. The SPCD should not duplicate information in the COSPP.

Improper marking or lighting of runways, taxiways and displaced thresholds.

Attractions for birds such as trash, grass seeding or ponded water on or near the airfield.

Inadequate or improper methods of marking temporarily closed airport operations areas, including improper and unsecured barricades.

Obliterated markings on active operational areas.

ADC Project No. 21179 Page 6 12/02/2021

Encroachments to apron, taxiway or runway clearance areas, improper ground vehicle operations and unmarked or uncovered holes and trenches in the vicinity of aircraft operating surfaces are the three most recurring threats to safety during construction.

E. Vehicles on the Airfield

Vehicular activity on the airfield movement areas should be kept to a minimum. Where vehicular traffic on airfield operational areas cannot be avoided, it should be carefully controlled. A basic guiding principle is that the aircraft always has the right-of-way. Some aspects of vehicle control and identification are discussed below. It should be recognized, however, that every airfield presents different vehicle requirements and problems and therefore needs individualized solutions so vehicle traffic does not endanger aircraft operations. All vehicle operations shall be carefully coordinated with airfield operations.

1. Visibility

Vehicles which routinely operate on airport operations areas should be marked and/or flagged for high daytime visibility and, if appropriate, lighted for nighttime operations. Vehicles which are not marked and lighted may require an escort by one that is equipped with temporary marking and lighting devices. (See Air Force T.O. 36-1-191 and FAA AC 150/5210-5.)

Contractor’s vehicles and equipment shall be marked with flashing amber lights and flagging as indicated under the “Safety” section on project drawings.

2. Identification

Marking of vehicles and radio communication is addressed under the “Safety” section on project drawings.

3. Noticeability

Construction vehicles and equipment shall have automatic signaling devices to sound an alarm when moving in reverse.

4. Movement

Contractor coordination with airfield operations for control of vehicular activity on airfield operations areas is of the highest importance.

F. Inspection

Contractor shall conduct daily inspections of all operational safety elements and shall maintain a log of safety inspections for the duration of construction.

G. Special Safety Requirements During Construction

1. Taxiways and Aprons

Refer to the project drawings for all work in proximity to Towway Echo.

2. Excavation and Trenches

Along taxiways and aprons, excavation and open trenches may be permitted up to the edge of structural taxiway and apron pavements, provided the drop-off is adequately signed, lighted and marked.

ADC Project No. 21179 Page 7 12/02/2021

3. Stockpiled Materials

Extensive stockpiled materials shall not be permitted within the construction activity areas that are aircraft management areas, in the proximity of navigational aids, within a runway safety area, runway obstacle free zone or runway object free area.

Repair IMC Pavements Area F - Charleston Air Force Base

Charleston, South Carolina

S&ME Project No. 214680

Dear Mr. Jones:

We are pleased to submit our pavement exploration for IMC Area F at the Charleston Air Force Base located in

North Charleston, South Carolina. Our services were performed pursuant to S&ME Proposal No. 214680 dated

May 11, 2021. The purpose of our services was to explore the site subsurface conditions, evaluate those conditions, and provide a data report. This report presents our understanding of the project, the site and subsurface conditions encountered, and our conclusions and recommendations.

Project Information

We understand plans are underway to repair/replace the pavements in between Building 578, Building 575, and the tow way to the northwest. We understand that the pavements will be subjected to light passenger trucks, delivery trucks, and towed planes. Determination of the existing pavement thickness and shallow subsurface exploration were requested to determine site preparation and determine the compaction of the near surface soils.

Project information was provided by Mr. Greg Jones to Mr. Kyle Murrell on May 10, 2021 in an e-mail with survey limits, Statement of Work (SOW) dated October 29, 2020, and referencing the revised design work order DKFX 09-

1009F, Opportunity 10169806.

Methods of Exploration

Our field exploration included a site reconnaissance by a Geotechnical Staff Professional and the performance of six pavement cores with Dynamic Cone Penetrometer (DCP) tests and 4-ft-deep hand-auger borings. The borings were advanced to a depth of 4-ft below the ground surface, and the soils encountered were visually classified using the Unified Soil Classification System (ASTM D 2488). DCP testing was performed at each location within the top 24-in., in general accordance with ASTM D6951 for correlation to an in-situ California Bearing Ratio (CBR). At location B-4, the coring bit refused at approximately 3¼ ft within concrete, and a hand-auger boring and DCP test were not performed.

The test locations were established in the field by an ADC representative. Test locations were spaced to characterize different section of existing pavements. The approximate locations are shown on the Test Location

Plan (Figure 1) in the Appendix. A more detailed description of our field-testing procedures, the Hand-Auger boring Logs, and DCP data sheets are also included in the Appendix.

Site, Pavement, and Subsurface Conditions

Site Conditions

The subject site is a paved area between multiple buildings and drive lanes. The pavements are gradually sloped away from the centerline of the drive lanes. The subject site is bordered by a building to the north, buildings to the east and south east, and a tow way along the west side of the site.

Pavements

The pavements were cored and then collected by ADC personnel. The holes were backfilled with soil cuttings and grouted to the top of the finished pavements. The pavement thicknesses are presented in Table 1.

Subsurface Conditions

Details of the subsurface conditions encountered by the hand-auger borings are shown on the logs and DCP data sheets in the Appendix. These logs represent our interpretation of the subsurface conditions based upon field data. Stratification lines on the sounding logs represent approximate boundaries between soil types; however, the actual transition may be gradual.

Borings B-1, B-2, B-4, and B-5

At these borings, we encountered 5 to 14 in. of asphalt above 7 to 7½ in. of concrete. At B-4, the coring rig was not able to penetrate through the concrete. Under the concrete, the exploration encountered sandy fill soils with traces of crushed stone to depths of 2 to 3½ ft below the pavement surface. The exploration then encountered natural sands with varying fines contents (i.e. silts/clays) to the deepest explored depth of 4 ft.

Boring B-3

At boring B-3, the exploration initially penetrated 3¾ in. of asphalt underlain by 8¾ in. of crushed stone base course. Below the pavement section, the exploration encountered sandy fill soils with varying fines content and contained trace amounts of roots. Fill soils were encountered to the deepest explored depth of 4 ft below existing pavement surface.

Boring B-6

At boring B-6, the exploration initially penetrated 7¼ in. of concrete. Underneath the concrete, the exploration encountered sandy fill soils with varying fines contents and trace amounts of crushed stone to a depth of 3¾ ft below the ground surface. The borings then encountered native silty sands with some organic roots to the deepest explored depth of 4 ft below the existing pavement surface.

CBR Correlation

Based on extensive correlation data between the DCP results and laboratory California Bearing Ratio (CBR) testing developed by the USACOE, the DCP data obtained during our field exploration was used to evaluate an in-situ

CBR value within the existing pavement area in Area F. The data indicates in-situ CBR values vary from 8 to over

30. We recommend a CBR value of 10 percent be used of design of new pavements.

Controlled Fill Recommendations

If existing pavements are demolished and grading is necessary, controlled fill material should be cohesionless soil containing no more than 15% fines (material passing the No. 200 sieve) by weight and having a maximum dry density of at least 100 pcf as determined by a laboratory standard Proctor compaction test (ASTM D689). The soil should be relatively free of organics, deleterious matter, and elongated or flat particles susceptible to degradation.

All fill should be placed in uniform lifts of 10 in. or less (loose measure) and compacted to at least 95% of the standard Proctor maximum dry density.

Fill placement should be observed by a qualified engineering technician working under the direction of the

Geotechnical Engineer. In addition to this visual evaluation, the technician should perform a sufficient number of in-place field density tests to confirm the contractor’s equipment and methods are capable of achieving the required degree of compaction.
