STATEMENT OF WORK (DRAFT)

RESTRIPE 500 RAMP AREA, PHASE II OF STRIPING PLAN

TRAVIS AFB CALIFORNIA

Base Project Number: XDAT 20-1040

DATE: 21 October 2024

1. INTRODUCTION

The Contractor shall be responsible for all professional services, permits, equipment, labor, tools, materials, and ancillary items necessary to complete the tasks to restripe 500 ramp area and nearby taxiways.

2. SCOPE OF WORK

The performed tasks shall be based on the project description, other data furnished in this Statement of Work (SOW), and information covered during the Pre-Construction (Pre-CON) meeting. The scope of this project includes re-design and restripe or place new pavement markings along the 500 ramp, Taxiway J, portion of Taxiway L leading up to Hangar 808, Taxiway N, and Taxiway V at Travis AFB, CA

2.1. Restripe all pavement lines and markings within the boundary indicated in Attachment 1 IAW the current UFC3-260-04.

2.2. Provide surveying services to ensure current design drawings are accurate and modify design IAW the current UFC 3-260-04.

2.3. Obtain paint chip samples from various location to test for lead before striping removal (see Attachment 2 for location reference). Submit test report to government for verification.

5. ADDITIONAL DRAWING COMMENTS

5.1. General:

5.1.1. Sheet G-002, Note 8 – Please note general work hour does not applied; please work with airfield management for schedule/time approval prior to striping work.

5.1.2. Sheet G-002, Note 10, Sheet G-003, General Environmental Notes 2, and Conservation

Measures Note 2 – Please note base would prefer to have work on dry season; however, work is allowed if the weather permits and all ground is properly dry (48 hours after rain event).

5.1.3. Throughout all CD sheets – Lead abatement is considered different site condition if test result shows that lead abatement/disposal is necessary.

5.2. Striping Plan Drawing:

5.2.1. Sheet C2-101, Quadrant D1 – Remove northernmost Entry Control Point (ECP) for Hangar

809. Drawing indicates 2 ECPs, and it should only be 1 ECP (the southernmost ECP, as is currently placed).

5.2.2. Sheet C2-101, Quadrant C-2 – Re-design towway line so that it is a minimum of 37.5’ from apron/towway boundary marking (leading from Twy L to Towway V and toward Hangar 809).

Create new designation to be used in design/legend for the Towway Centerline (consider TOWCL for towway centerline since TCLS is used taxiway centerline stripe).

5.2.3. Sheet C2-101, Quadrant B-2 – Extend restricted area boundary through AC shoulder to butt against Hangar 810. Current drawing has line stopping at apron boundary marking.

5.2.4. Sheet C2-101, Quadrant C-3 – Remove westernmost Entry Control Point (ECP) for Hangar

808. Drawing indicates 2 ECPs, and it should only be 1 ECP (the easternmost ECP, as is currently placed).

5.2.5. Sheet C2-101, Quadrant C-3 – Relocate Taxiway Edges Stripes (TWES), to align with current placement (match existing). Design indicates that aircraft are able to be towed on Industrial Road (leading northeast from Taxiway Lima). Current placement is that the edge markings come out perpendicular from the eastern edge of Twy L as it approaches Hangar 808, then makes a 90 degree turn to the north leading toward Hangar 808. Current placement is correct, design is incorrect. Ensure that the new TWES is located 37.5’ from centerline.

5.2.6. Sheet C2-101, Multiple Quadrants – Remove Deceptive Surface Markings (DSMs) within AC shoulders for Towway V and hangar access aprons for Hangars 808-810.

5.2.7. Sheet C2-101, Multiple Quadrants – Reconfigure Taxilane Centerline Stripes (TCLSs) on Taxiway Lima south of the Towway V/Twy L intersection and all other pavements within the work area to be towway markings. Redesign to retro-reflective white markings. Add “TOW ONLY” on Taxiway Lima south of the Towway V/Twy L intersection.

5.2.8. Sheet C2-102, Spot 511, Quadrants B1 & B2 – Design does not reflect non-stressed pavement “islands”. Update design to match existing, which includes TWES around the non-stressed AC at the parking spot.

5.2.9. Sheet C2-102, Spot 511, Quadrants B1 & B2 – Design does not reflect existing pavement/parking spot design. Remove “extra” set of TWES and DSM, replace TWES and add DSM at correct location.

5.2.10. Sheet C2-102, Spot 512, Quadrants A1, A2, B1, & B2 – Design does not reflect non-stressed pavement “islands”. Update design to match existing, which includes TWES around the non-stressed AC at the parking spot. Add DSM within non-stressed AC portions of the “island”.

5.2.11. Sheet C2-102, Quadrant B2 – Missing Surface Painted Taxiway Direction Sign (SPTDS) for Spot 511 (left and right). Add these SPTDS adjacent to the TCLS of Taxilane J as they approach Spot 511 from both directions.

5.2.12. Sheet C2-102, Quadrant A3 – Add new Taxilane Edge Stripe (TLES) between Spot 412 and Spot 519. TLES will be placed 143’ south of Spot 412, and will protect the distinct aprons/parking spots.

5.2.13. Sheet C2-103, Quadrant B3 – Add new Taxilane Edge Stripe (TLES) between Spot 520 and the towway for Spot 521. TLES will be placed 143’ north of the towway leading into Spot 521 to protect parking spot 520 and the towway.

5.2.14. Sheet C2-103, Quadrants D1 & D2 – Design does not reflect non-stressed pavement “islands”.

Update design to match existing, which includes TWES around the non-stressed AC at the parking spot.

5.2.15. Sheet C2-104, Multiple Quadrants – Recommend including TWES on drawing for Twy N to indicate to the contractor that they have to remove/repaint the TWES for Twy N. It only points out the TWES for Spot 521.

5.2.16. Sheet C2-106, Quadrant B2 – Add Surface Painted Taxiway Direction Sign (SPTDS) for Twy

N on Twy J; signs are missing from design but painted to non-standardized marking currently (extremely faded). These signs need to be placed 163’ from Twy N centerline. Will be on left and right side of taxiway, with arrows in both directions.

5.2.17. Sheet C2-106, Quadrants A2, B2, & B3 – Remove TLES that crosses Twy J and is parallel to Twy N. Only remove the TLES that is between the TLES for Twy J.

5.2.18. Sheet C2-108, Quadrant D2 – Remove TLES that crosses Twy J and is parallel to Twy N. Only remove the TLES that is between the TLES for Twy J.

5.3. Pavement Marking:

5.3.1. Sheet C2-502 – Add design guidance for Towway Centerline marking, to include color, retro-reflectivity, stripe width, and black (non-retro-reflective) border. Similar to #1 for the TCLS, but white instead of yellow.

5.3.2. Sheet C2-503, all surface painted signs –

• Correct distance of sign to centerline to show 3’ between centerline (not including border line) and sign background (not including border line). As shown on design, it is 3’ from the centerline border to the numeral, which is incorrect.

• Correct height of letters/numbers to 12’, as opposed to the 6’ and 9’ that is show in design.

• Correct arrows to not be in a “bent” orientation; arrows should be straight and canted in the orientation/direction that the aircraft is expected to turn. Correct sizing of arrows, IAW

UFC 3-260-04.

5.3.3. Sheet C2-504, Figure 3 – Change ECP to current UFC guidance. Red line, with white transverse bars intersecting the restricted area line. White transverse bars must include black border. Neither the white transverse bars nor black border is not to cover/cross the retro-reflective red restricted area boundary marking.
