Project Summary: Ashland Municipal Airport Taxiway Reconstruction and Rehabilitation

This comprehensive design document package pertains to the City of Ashland's reconstruction and rehabilitation of Taxiway A and associated infrastructure at Ashland Municipal Airport (Sumner Parker Field) in Ashland, Oregon. The project, designated A.I.P. No. 3-41-0002-013-2021 with project number 12403.005.01, encompasses the full-depth reconstruction, grading, and electrical improvements of approximately 40 linear miles of taxiway pavement, along with stormwater management, erosion control, and lighting system upgrades. The work is organized into three distinct work areas: Work Area #1 extends from Taxiway A6 to the northern side of Taxiway A3 (STA 5+00 to 32+77) under Schedule A; Work Area #2 covers the same area within the runway obstacle-free zone requiring runway closure, also under Schedule A; and Work Area #3 extends from STA 32+90 to approximately STA 44+00 for crack and slurry seal work under Schedule B. The total contract duration is 90 calendar days, with a single 15-day continuous runway closure permitted within that period for Work Areas #2 and #3, which must be completed concurrently. The contract documents indicate an anticipated start date of August 2022 with completion targeted for November 2022.

The project incorporates extensive infrastructure improvements including 6-inch perforated high-density polyethylene underdrains throughout the taxiway system, stormwater management with multiple outfalls and cleanouts, demolition of existing culverts, and installation of new electrical systems comprising taxiway edge lighting, guidance signage, junction base cans, and primary loop cable for the Medium Intensity Runway Lighting (MIRL) system. Pavement specifications call for 3 inches of asphalt concrete (P-403) over 9 inches of aggregate base course (P-208), with cement-treated subgrade (P-156) stabilization where required. The project requires contractor compliance with airport safety procedures, maintenance of public access to facilities, protection of existing utilities, and adherence to Oregon Department of Environmental Quality stormwater pollution prevention requirements. Liquidated damages will be assessed if work is not completed within the specified calendar day periods, and the contractor must maintain equipment height limitations of 10 feet, stockpile height limits of 10 feet at least 195 feet from the runway centerline, and control dust throughout construction activities.

TAXIWAY.

4. SAFETY AREA LIMITS

TAXIWAY - 24.5' FROM

RUNWAY 12-30 - 60' FROM ; 240' FROM

THRESHOLD

5. RUNWAY AND TAXIWAY OBJECT FREE AREAS/ZONES ARE

DEFINED AS AREAS THAT SHALL BE CLEAR OF FIXED OR

MOVABLE OBJECTS. WORK MAY OCCUR IN RUNWAY OBJECT

FREE AREAS, HOWEVER, EQUIPMENT NOT IN USE, AND

MATERIAL STOCKPILES AND STORAGE SHALL BE PLACED AT

LEAST 125 FEET FROM ANY RUNWAY CENTERLINE. NO WORK

MAY OCCUR IN TAXIWAY OBJECT OBJECT FREE AREAS UNLESS

THE TAXIWAY IS CLOSED TO AIRCRAFT TRAFFIC. NO STORAGE

OF EQUIPMENT, MATERIALS OR STOCKPILES IS ALLOWED

WITHIN TAXIWAY OBJECT FREE AREAS.

6. OBJECT FREE AREA/ZONE LIMITS

TAXIWAYS - 44.5' FROM

RUNWAY 12-30 - 125' FROM

7. RUNWAY AND TAXIWAY SAFETY AREA AND RUNWAY AND

TAXIWAY OBJECT FREE AREA CRITERIA MUST BOTH BE MET

PRIOR TO OPENING AN IMPACTED RUNWAY OR TAXIWAY.

SEQUENCING AND PHASING NOTES:

1. ALL WORK SHALL BE COMPLETE WITHIN 90 CALENDAR DAYS OF

CONTRACT NOTICE TO PROCEED. REFER TO DETAIL 3, THIS

SHEET.

2. ONE RUNWAY CLOSURE OF 15 CONTINUOUS CALENDAR DAYS

IS ALLOWED. THIS CLOSURE SHALL OCCUR WITHIN THE 90

CALENDAR DAY PERIOD AS DESCRIBED IN NOTE 1 ABOVE.

3. WORK IN WA #1 SHALL BE COMPLETED IN 90 CONTINUOUS

CALENDAR DAYS. IF WORK IS NOT COMPLETE WITHIN THE 90

CALENDAR DAY PERIOD, LIQUIDATED DAMAGES WILL BE

ASSESSED.

4. WORK IN WA #2 AND WA #3 WILL REQUIRE A RUNWAY CLOSURE

AND SHALL BE COMPLETED IN 15 CONTINUOUS CALENDAR

DAYS. IF WORK IS NOT COMPLETE WITHIN THE 15 CALENDAR

DAY PERIOD, LIQUIDATED DAMAGES WILL BE ASSESSED. WORK

IN WA #2 AND WA #3 SHALL BE CONCURRENT.

5. WORK EXEMPT FROM EACH CALENDAR DAY CONTRACT PERIOD

INCLUDES THE SECOND APPLICATION OF PAVEMENT

MARKINGS. A CONTINUOUS 1 CALENDAR DAY (24 HOUR)

CLOSURE FOR THE SECOND APPLICATION OF PAVEMENT

MARKINGS WILL BE PERMITTED, A MINIMUM OF 30 DAYS AFTER

PAVING OPERATIONS HAVE BEEN COMPLETED.

6. THE RUNWAY 12 PAPI CAN BE OUT OF SERVICE FOR UP TO 15

CALENDAR DAYS OUTSIDE THE RUNWAY CLOSURE DATES TO

ALLOW THE CONSTRUCTION OF THE NEW PAPI ELECTRICAL

LINE. NOTIFY THE ENGINEER A MINIMUM OF 7 DAYS IN

ADVANCE OF DE-ENERGIZING THE RUNWAY 12 PAPI.
