GEOTECHNICAL NOTES

DESIGN AND CONSTRUCTION OF TEMPORARY UNPAVED AIRCRAFT-TOWING ACCESS ROAD AND RAMP:

1. SUBMIT DRAWINGS AND CALCULATIONS, CERTIFIED BY A UTAH LICENSED PROFESSIONAL ENGINEER WITH 3 YEARS OF RELEVANT GEOTECHNICAL EXPERIENCE IN AIRFIELD DESIGN AND THE UTAH GREAT SALT LAKE REGION, DESCRIBING THE METHODS FOR THE TEMPORARY UNPAVED ACCESS ROAD AND RAMP SYSTEM.

DRAWINGS MUST INCLUDE MATERIAL SIZES AND TYPES AND THE SEQUENCE AND METHOD OF

INSTALLATION AND REMOVAL. CALCULATIONS MUST INCLUDE DATA AND REFERENCES USED.

2. SUBSURFACE INFORMATION INCLUDING BORING LOGS AND LABORATORY TEST RESULTS AND THE SPECIFICATIONS OF THE C-130J AND C-130J-30 HERCULES AIRCRAFT ARE INCLUDED IN THE SPECIFICATION SECTION 31 00 00 AS PART OF THE CONSTRUCTION DOCUMENTS. CONTRACTOR MUST SUBMIT THE

TEMPORARY UNPAVED ACCESS ROAD AND RAMP DESIGN, INCLUDING MATERIAL GRADATION, AND

SUBGRADE CBR TEST RESULTS IN ACCORDANCE WITH SPECIFICATION SECTION 01 33 00 - SUBMITTAL

PROCEDURES, A MINIMUM OF 30 DAYS PRIOR TO STARTING WORK.

a. THE UNPAVED AIRCRAFT TOWING ROAD MUST BE DESIGNED USING THE LATEST VERSION OF THE PAVEMENT-TRANSPORTATION COMPUTER ASSISTED STRUCTURAL ENGINEERING (PCASE) SOFTWARE

AVAILABLE FROM THE TRI-SERVICE TRANSPORTATION WEBSITE AS SHOWN BELOW:

HTTPS://TRANSPORTATION.ERDC.DREN.MIL/PCASE/SOFTWARE.ASPX

b. THE SLOPE OF THE RAMP MUST NOT BE STEEPER THAN 1 VERTICAL TO 15 HORIZONTAL RATIO IN THE DIRECTION OF AIRCRAFT TRAVEL. THE DESIGN MUST DEMONSTRATE THAT ALL PARTS OF THE AIRCRAFT (NOSE, TAIL, AND WINGS) ARE CLEAR FROM THE GROUND AND THE HANGAR STRUCTURE DURING THE

TOWING OPERATION.

c. THE DESIGN MUST ALSO INCLUDE SLOPE STABILITY ANALYSES TO ENSURE THE RAMP CAN PROVIDE

STABILITY AGAINST FAILURE DURING THE TOWING OPERATION.

d. TEMPORARY ROAD AND RAMP MUST BE CONSTRUCTED USING THE SAME TYPE OF AGGREGATE BASE COURSE MATERIAL AS SHOWN IN PARAGRAPHS UNDER “PART 2 – PRODUCTS” OF THE SPECIFICATION

SECTION 32 11 23 COMPACTED TO AT LEAST 95% OF THE LABORATORY MAXIMUM DENSITY.

3. THE THICKNESS OF THE BASE COURSE SPECIFIED IN THE DESIGN OF THE ACCESS ROAD AND RAMPS MUST BE NO LESS THAN 6". PRIOR TO TRAFFICKING THE RAMPS, THE CONTRACTOR MUST PROOF

LOAD, WITH A FULL WATER TRUCK OR LOADED DUMP TRUCK, THE RAMPS TO ID ANY UNSTABLE

AREAS. IF UNSTABLE AREAS EXIST, THE BASE WILL PROVIDE AND PLACE AM-2 MAT OVER THE AREAS TO ALLOW FOR TRANSIT OF AIRCRAFT AND TOW VEHICLES. THE BASE IS RESPONSIBLE FOR TOWING

THE AIRCRAFT AND REMOVING THE AM-2 IF USED.

PHASING PLAN LEGEND

PAVEMENT REPLACEMENT AREA

CONTRACTOR STAGING AREA

OVERALL PHASING NOTES

1. THE PROJECT IS LOCATED WITHIN A RESTRICTED/CONTROLLED AREA AND THEREFORE CONSTRUCTION ACTIVITIES (INCLUDING DEMOLITION) CANNOT START UNTIL A FREE ZONE (FZ) APPLICATION IS APPROVED BY THE USER/CUSTOMER AND THE 75TH OSS/RESTRICTED AREA. PLEASE SEE AIRFIELD SAFETY SPEC

SECTION FOR THIS SUBMITTAL REQUIREMENT.

2. FREE ZONE AREA TO BE ESTABLISHED BY THE CONTRACTOR AFTER LIMITS OF FREE ZONE AREA IS COORDINATED AND APPROVED BY THE CONTRACTING OFFICER INCLUDING INPUTS FROM AIRFIELD MANAGEMENT AND SECURITY FORCES. THE CONTRACTOR SHALL COMPLY WITH ALL IDENTIFICATION BADGING, VEHICLE PASSES, ESCORTS, FLIGHT LINE DRIVER TRAINING, COMPANY LOGO VEHICLES, ETC AS REQUIRED WHEN TRAVELING THROUGH THE AIRFIELD ENVIRONMENT TO AND FROM THE FREE ZONE AREA. THE CONTRACTOR VEHICLES AND PERSONNEL MAY MOVE FREELY WITHIN THE FREE ZONE AREA

ONCE THEY HAVE ARRIVED.

3. ALL WORK SHALL BE PHASED TO MINIMIZE IMPACT TO THE APRON. WORK SHALL BE SCHEDULED AND

COORDINATED WITH THE CONTRACTING OFFICER/AIRFIELD MANAGER PRIOR TO APPROVAL OF

CONTRACTOR'S SCHEDULE. WORK TO BE DONE IN THIS AREA SHALL BE CLEARLY IDENTIFIED IN THE

CONTRACTOR'S SCHEDULE.

4. GATE AT THE CONTRACTOR ACCESS SHALL REMAIN OPEN DURING CONSTRUCTION. CONTRACTOR SHALL PROVIDE PERSONNEL TO PROVIDE TRAFFIC SAFETY, MAINTAIN FOD CHECKPOINT AND RESTRICT

ACCESS TO SITE TO AUTHORIZED PERSONNEL.

5. ALL AIRCRAFT OPERATING ADJACENT TO WORKING AREAS WILL BE TOWED AND NOT UNDER POWER.

6. CONTRACTOR WILL BE RESPONSIBLE FOR REPAIRING ANY DAMAGE TO EXISTING ROAD WAY AND

AIRFIELD PAVEMENT CAUSED BY CONSTRUCTION TRAFFIC.

7. CONTRACTOR TO SWEEP UP ANY FOD OUTSIDE FREE ZONE GENERATED FROM THE PROJECT.

8. EQUIPMENT STAGING AREA SHOWN ON THIS SHEET IS APPROXIMATE. ACTUAL LOCATION SHALL BE COORDINATED WITH CONTRACTING OFFICER OR PROJECT MANAGER. SEE SHEET G-101 FOR LOCATION

OF CONTRACTOR TRAILER AND MATERIALS STAGING AREA.

9. AIRCRAFT TRAFFIC SHALL NOT BE ALLOWED ON THE NEW CONCRETE PAVEMENT BEFORE THE

REQUIREMENTS UNDER PARAGRAPH "PAVEMENT PROTECTION" IN SPECIFICATION SECTION 32 13 14.13

ARE MET.

10. PRIOR TO OPENING ANY RUNWAY, TAXIWAY, OR TOWWAY PAVEMENTS AT THE END OF A PHASE, THE CONTRACTOR SHALL REMOVE ALL LOOSE MATERIALS AND FOREIGN OBJECT DEBRIS (FOD) FROM THE PAVEMENT SURFACES. ONCE THE PAVEMENTS AREA IS APPROVED BY AIRFIELD MANAGEMENT FOR

AIRCRAFT OPERATIONS, THE CONTRACTOR SHALL REMOVE THE BARRICADES..

11. IN THE EVENT THAT NEW CONCRETE PAVEMENTS HAVE NOT BEEN COMPLETED WHEN A C-130 AIRCRAFT IS TO BE TOWED IN OR OUT OF HANGAR 206, A TEMPORARY UNPAVED ACCESS ROAD AND RAMPS INTO AND OUT OF THE EXCAVATION WILL NEED TO BE CONSTRUCTED. THE SURFACE OF THE RAMP MUST BE

A MINIMUM OF 25' WIDE.

12. ANTICIPATED AIRCRAFT REQUIRING ACCESS TO APRON AND HANGARS DURING CONSTRUCTION: C-130, F-35, F-16 AND A-10.

13. LOW PROFILE BARRICADES ARE LOCATED AS INDICATED ON THE INDIVIDUAL PHASING SHEETS.

14. ALL UTILITIES TO REMAIN IN SERVICE DURING CONSTRUCTION. THE TIMING AND DURATION OF ANY SHUT

DOWNS OR OUTAGES MUST BE COORDINATED AND APPROVED BY HILL AFB. THE CONTRACTOR IS

RESPONSIBLE TO PROVIDE SUFFICIENT TIME IN THE SCHEDULE TO ALLOW FOR COORDINATION AND

NOTIFICATION PRIOR TO THE WORK BEING PERFORMED.

15. AIRCRAFT HANGARS 233, 10-206, 206 AND 225 SHALL BE REMAIN ACCESSIBLE TO AIRCRAFT TRAFFIC

DURING ALL PHASES. TEMPORARY RAMPS TO HANGAR FLOORS WILL NEED TO BE CONSTRUCTED.

16. REMOVE AND REPLACE BARRICADES WHEN AIRCRAFT REQUIRE ACCESS TO THE HANGAR/APRON.
