I. PROJECT DATA Addison Airport Addison, Texas Rehabilitate Runway 15-33, Mark, Groove and Lighting (MIRL) II. SITE INFORMATION Addison Airport is located in the Town of Addison, in
Dallas County, -Texas, approximately 12 miles north of the Dallas Central Business District. Three communities surround the Town of Addison, including: Carrollton along the northwest
and western border of the airport; the City of Dallas located one half-mile to the north and one and one-half miles to the southeast of the airport; and Farmers Branch located approximately
one-half mile south of the airport. Major roadways in the airport vicinity include Midway Road to the west, Belt Line Road to the south, Trinity Mills Road to the north and Addison Road
to the east of the Airport. Addison Airport encompasses approximately 368 acres and is classified as a reliever airport. Addison Airport serves the Dallas-Fort Worth metropolitan areas
as a corporate and general aviation facility. Addison Airport currently has a single bituminous runway with a bituminous parallel taxiway system. Runway 15-33 is 7,199 feet long by 100
feet wide. Taxiways are 50 feet wide, with the exception of Taxiway C which is 25 feet wide. The runway pavement strength is rated for single-wheel aircraft up to 80,000 pounds, 1 
dual wheel aircraft up to 100,000 pounds, and dual-wheel tandem gear aircraft up to 120,000 pounds maximum takeoff weight. The transverse grade of the existing runway pavement is very
flat, and does not promote drainage across its surface. Ponding occurs on the 􀁾􀁵􀁮􀁷􀁡􀁹􀀠which poses a safety problem. III. DESCRIPTION OF WORK This project consists of rehabilitating
Runway 15-33 and installing new medium intensity runway lights (MIRL), and the associated electrical vault work. The rehabilitation of the runway will include constructing a crowned
section on the runway using a nominal one and one-half inch bituminous overlay, grooving the pavement to promote drainage, and pavement marking. IV. VERTICAL PROFILES AND TRANSVERSE
GRADES The longitudinal slope of the runway generally follows the gradient of the surrounding terrain with slopes ranging from -0.50% to 0.52%. The transverse slope of the runway is
relatively flat in the center 50' of the runway. From the centerline of the runway to about 25' out, the transverse slope ranges from 0% to -0.9%. The transverse slope of the outer 25'
of the runway ranges from -0.98% to -2.22%. The longitudinal slope of the connector taxiways adjacent to the runway range from -2.90% to +1.0%. 2 
The transverse slope of the connector taxiways, within the area of the runway overlay tie-in is generally -0.5% to -1.5%. V. SUB-SURFACE CONDITIONS Southwestern Laboratories conducted
a pavement coring and soil boring 􀁾􀁲􀁯􀁧􀁲􀁡􀁭􀀠of the existing runway and taxiway pavements and subsurface components. A copy of their Preliminary Report is attached as Appendix "A"
to this report. VI. SUMMARY OF TEST DATA This section to be completed upon receipt of geotechnical report. VII. PAVEMENT DESIGN The existing flat transverse grade across the runway allows
ponding to occur and poses a safety hazard during rainy weather. The proposed overlay along with transverse grooving, will promote positive drainage toward the runway edges and eliminate
the ponding. The existing pavement strength of Runway 15-33 satisfies the requirements of the design aircraft, Grumman Gulfstream II, as identified in the Airport's Master Plan. The
proposed overlay, although not required for strength, will increase the strength capacity of the the runway. The overlay shall be constructed so that the minimum thickness added to the
runway is one and one-half inch throughout. In some cases this adds three to four inches to the 3 
center of the runway. All pavement constructed shall meet FAA specifications P-401 Bituminous Plant Mix Pavements. VIII. CONSTRUCTION METHODS The runway overlay shall be constructed
on top of the existing runway surface following the profile and transverse grades as established in the plans. The existing pavement surface shall be cleaned of debris prior to the application
of the bituminous tack coat. IX. STRUCTURAL DESIGN There is no structural design for this project. X. HARKING All marking conforms to FAA Specification P-620 Runway and Taxiway Painting,
and FAA Advisory Circular 150/5340-1F (Change 1). XI. TURFING All disturbed areas shall be returned to their original condition. In areas requiring seeding and mulching, seeding shall
be in accordance with FAA Specification T-901. The seed variety and fertilizer to be used are those that have been used on previous work at Addison Airport. 4 
XII. LIGHTING Medium intensity runway lights (MIRL) shall be Jnstalled along the edges of the runway in accordance with Advisory Circulars 150/534024 and 150/5345-46A, and FAA Specifications
L-108, L-109·and L-110. The existing edge lighting system shall be removed and salvaged. The 􀁥􀁬􀁥􀁾􀁴􀁲􀁩􀁣􀁡􀁬􀀠vault is proposed to be moved to the west side of the airport adjacent
to the existing FAA Air Traffic Control Tower (ATCT). A new regulator shall be installed for the MIRL's. XIII. DEV7ATION FROM STANDARDS Two existing taxiways do not meet current FAA
criteria. Taxiway "B-B" 's elevation exceeds that of the runway, thus violates the Part 77 Primary Surface by approximately a foot and a half. Taxiway "C'lts longitudinal gradient exceeds
the maximum allowable as per Advisory Circular 150/5300-13, 1.5%. To lower Taxiway "B-B" below the Part 77 surface and meet taxiway gradient criteria would require reconstruction of
about 700' of taxiway including the intersection of Taxiway "A-A" and "B-B" at a considerable considerable expense. The Master Plan anticipates that the parallel Taxiway "A-A" will be
reconstructed closer to the runway in 1993, and will require reconstruction of the Taxiway "B-B" intersection at that time. As funds for the runway overlay project are limited, it is
recommended that the taxiway remain as it is and the runway overlay be tied back into the existing taxiway with a vertical curve of 100' length. Reconstruction of the taxiway should
be included in Taxiway "A-A" construction. 5 
Approximately one hundred feet of the longitudinal grade of Taxiway "c" starting from the edge of the runway 􀁩􀁾􀀠-2.9%. To meet standards, about 200' of Taxiway "c" would have to be
reconstructed a foot and a half higher than its existing elevation at a considerable expense. The Master Plan indicates that this taxiway is to 1;>e widened from 25' to 50', and is anticipated
to be overlayed as part of a taxiway strengthening project proposed to be constructed in 1993. As funds for the runway overlay project are limited and the taxiway is presently functioning
without noted problems, it is recommended that the existing profile be retained, and that the runway overlay be tied into the existing taxiway surface with vertical curves to provide
a smooth transition. XIV. CONSTRUCTION SEQUENCES In the Preliminary Engineering stage of the project development, three alternative construction phasing plans were developed, reviewed
and coordinated with FAA, the Sponsor and local users. From the review process, a final phasing plan has been developed and a brief summary of the phases, work-activities and anticipated
construction time follows: The total contract time is 108 calendar days and is subdivided into two subphases: Phase A, 16 calendar days, will inclUde: * contractor mobilization, 14 calendar
days; 6 
* Displace Runway 15 threshold 730 feet south on day 15 at 9:00 p.m. Maintain displacement 􀁵􀁮􀁾􀁩􀁬􀀠day 17 at 6:00 a.m., at which time the runway is opened to its normal length; *
Paving, lighting (MIRL) and marking of the northern 730 and connector Taxiways G and H. Construction activities occur 24 hours a day; * Construction of Airfield Lighting Vault building.
Phase B, 92 calendar days, will include: * Removal of Runway 15 threshold displacement; * Close the runway at night between the hours of 9:00 p.m. and 6:00 p.m.; * Paving, lighting (MIRL)
and marking of the souther 6,470 feet of the runway during night time closure; * Grooving and final marking of the runway during night time closure of the runway; * Construct Airfield
Lighting Vault building (continuation of Phase A work). XV. SOURCE OF HATERIALS All materials for this project will be furnished by the Contractor from sources of his choice. Material
shall be in accordance with Advisory Circular 150/5370-10A FAA Standards for Specifying Construction on Airports. 7 
XVI. AVAILABILITY OF CONTRACTORS The project will be advertised in local 􀁾􀁥􀁷􀁳􀁰􀁡􀁰􀁥􀁲􀁳􀀠and the appropriate trade journals. This project is of large enough magnitude to draw a
significant number of contractors to ensure competitive bidding. The work involved is of the same nature as that 􀁮􀁯􀁾􀁡􀁬􀁬􀁹􀀠accomplished by contractors in the area. XVII. NON-AlP
WORK ITBHS All items within the project are eligible under the Airport Improvement Program funding. XVIII. WORK BY OTHERS No work shall be accomplished by forces other than those of
the contractor. XIX. ENGINEER'S ESTIMATE The Engineer's cost Estimate is attached as Appendix "B". XX. ENVIRONMENTAL CONSIDERATIONS The construction specifications contain clauses requiring
the contractor to take certain preventative measures to minimize the impact that the construction operations will have on the surrounding environment. The raising of dust will be minimized
by requiring the contractor to keep all haul roads and work areas dampened by watering. Areas exposed to excess of the standards during grading operations will be monitored from an erosion
control standpoint. 8 
All construction work will be accomplished in the strictest adherence to the most restrictive controls 􀁾􀁥􀁴􀀠forth in Texas Department of Transportation (TxDOT) and FAA Standard specifications.
XXZ • CqNTRACT TJ:ME The contract time for the project shall be 108 calendar days from the Notice-To-Proceed. XXJ:J:. LJ:QUZDATED DAMAGES Liquidated damages for contract overrun will
be $500 per calendar day over the contract time period allotted in the construction phasing plans from "Notice to Proceed". This amount has been established as an amount that will help
offset the cost for the services of inspection and testing beyond reasonable construction times. The amount should not cause any undue hardships to the Contractor since the construction
time as stipulated is reasonable. XXZZZ. DRAJ:NAGE Drainage improvements have just been completed at Addison Airport. Drainage improvements which shall be contributed by this project
include increasing the transverse grades from the runway centerline with a bituminous overlay and grooving the pavement to promote transverse drainage. Shoulders shall be improved to
promote positive drainage off of the pavement surface. 9
