STATEMENT OF WORK

RESTRIPE 500 RAMP AREA, PHASE II OF STRIPING PLAN

TRAVIS AFB CALIFORNIA

Base Project Number: XDAT 20-1040

DATE: 14 November 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). The scope of this project includes re-design and restripe or place new pavement markings along the 500 ramp, Taxiway C, Taxiway J, portion of Taxiway L leading up to Hangar 808, Taxiway N, and Taxiway V at Travis AFB, CA Comment by GERDTS, JAMES P MSgt USAF AMC 60 OSS/OSAA: Add Twy C as part of the drawings show Twy C as well.

2.1. Restripe all pavement lines and markings within the boundary indicated in Attachment 1 IAW the current UFC3-260-04. Paint must be quick-dry and airfield operations can be resumed within 20 minutes after restriping.

2.2. Provide low profile barricades to enclose free-zone on the airfield. Contractor would need to establish a free-zone within restricted area.

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

2.4. Obtain paint chip samples from various locations to test for lead before striping removal (see Attachment 2 for location reference). Submit test report to government for verification. If lead abatement/disposal is considered necessary after the test result, it is considered a different site condition.

3. SPECIFICATION

Particular attention shall be applied to the following standards and specifications:

If there is a conflict between codes, regulations and specifications, a Request For Information (RFI) must be submitted for government decision and approval. Documents listed by and/or provided by the Government are for reference only and do not relieve the Contractor from adherence with applicable codes not specifically addressed. Comment by GERDTS, JAMES P MSgt USAF AMC 60 OSS/OSAA: Recommend changing to say “submit an RFI to be adjudicated by 60 CES and 60 OSS.” “Most stringent” is subjective. Airfield Manager/Deputy Airfield Manager should have final determination of airfield markings.

4. ADDITIONAL REQUIREMENT

4.1. General:

4.1.1. The contractor will perform pre-survey of all pavement markings within the pavement area for the re-design. The contractor shall submit scaled/redlined striping plan for government approval prior to layout of markings.

5. ADDITIONAL DRAWING COMMENTS

5.1. General:

5.1.1. Sheet G-002, Note 8 – Please note general work hours do not apply; 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 ground is 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 –

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.
