the north side ofthe airplane hangars located south of Richard Byrd Drive in Addison, Texas. Scope ofServices Ifauthorized. OUT integrated services will include drilling of soil borings
by drill crews under our direct supervision, laboratory testing of representative soil samples for pertinent engineering properties, and preparation ofan engineering report. Eight (8)
borings will be drilled to a depth of about 5 feet below existing grade within the proposed pavement reconstruction aTeas. These borings will be advanced through boles cored/cut through
the existing pavements. Two bulk soil samples win also be obtained from Richard Byrd Drive to perform CBR tests. The holes will be backfilled with cuttings and the pavement surface patched
with cold-mix asphalt or ready-mix concrete. Upon completion of drilling operations, the samples will be subjected to laboratory tests (that can include moisture content, Atterberg limits,
and CBR tests) followed by the preparation of a written report. 4950 􀁬􀀼􀁥􀁬􀁬􀁾􀁲􀀠Springs Road, Suite 480, Addison, TX 15001 • (972) 392.3222 • FAX (912) 392.0102 • www.ecslimited.com

Issue Summary Chris: The project has been accepted by Council. After it was accepted, Initial problem was raveling of the seams between paver runs on the project. Raveling cannot be
tolerated due to damage to aircraft. Rebcon proposed cutting out the seams and replacing the pavement This was rejected by Lou E. for aesthetic reasons. Micro surfacing was proposed
as a solution but I believe that was rejected by Rebcon, probably due to cost. Lou E. suggested a slurry seal as a fix. The contractor agreed to apply a slurry seal as per FAA specs.
Contractor states Ihis cost $15,000. The problems that remain are: In hot weather, the slurry seal and underlying asphalt pulls up when a vehicle is parked for a while and the wheel
istumed. In hot weather the surface is soft such that a penknife can be sunk into the asphalt The surface is slippery such that aircraft owners have trouble pushing their planes into
Iheir hangars Our Engineer, HNTB has recommended milling off 1/4 inch of the surface and applying a 1 inch overlay. Cost estimated 10 be $52,000. We have about $20,000 in retainage that
we have not paid Rebcon. Our attomeys have demanded mediation as per the contract. The meeting we had on 1212 was 10 "air out" the issues prior to mediation. It was at this meeting that
Ron stated he wanted to take a look before we went any farther.. Jim Pierce, P.E. ASSistant Public Works Director P.O. Box 9010 AddIson, TX 75001-9010 972-45().2879 1

Chutchian, P.E. Assistant City Engineer Town ofAddison 16801 Westgrove Drive Addison, Texas 75001-9010 Re: Richard Byrd Drive Repairs Dear Mr. Chutchian: At your request, we have investigated
repair options for the Richard Byrd Drive pavement replacement project Mr. Mike Ebeling, P.E. and Mr. Michael Hutchison, P.E. visited the site on November 9, 2004 to evaluate repair
alternatives to the pavement. After assessing the condition of the area in question, we considered three options that would address the Town's concerns. The viable options are: I) Removal
and replacement ofthe entire three-inch asphalt surface course and restriping. 2) Milling one inch ofthe entire asphalt surface and applying a one inch overlay and restriping. 3) Milling
W' of the entire asphalt surface, edge milling the entire length of the north edge of the asphalt surface (along the hangar) as well as strategic areas on the south edge (to accommodate
drainage) and applying a one inch overlay and restriping. After careful consideration of the above alternatives, we recommend option three as the most practical option for this situation.
The W' milling over the entire surface is to remove the seal coat on the existing surface. The seal coat has the potential of reducing the bonding capability between asphalt layers.
The contractor will need to comply with all federal, state, and local regulations in hauling off the milled material. We have included the attached cost estimate of option three for
your use, and estimate the construction cost ofthis strategy to be approximately $52,000. Thank you for the opportunity to assist in this matter. Please contact me with any questions
you may have. Very truly yours, . Enclosure M:UOBS\39131-RichardByrdApronICOMMMTGSILETTERSlone inch overlay recommendation III004.doc The HNTB Companies OfflCES, IIlEXA>lDRI.'\. YA;

Town would like to kick off the design of the North Side of the Richard Byrd Drive Apron Project, Key issues paramount to this project are as follows: • The construction of the project
needs to be completed in as short a time frame as possible. It is estimated that approximately $80,000 in lost revenue occurred with the south side apron due to displacement of tenants.
• Construction phasing should be developed to minimize construction duration. Unlike the south side project, there will be no available hangars to displace tenants, • The recent batch
plant site was suggested as a possibility of temporarily parking aircraft. Luis E. indicated that, even though Site Concrete had repaired this area, there is too much potential for foreign
object damage (FaD) at this location to park aircraft there, • No federal funds will be used on this project. Therefore, plans will not be subject to TxDOT review, • Jim P. indicated
that he would like to utilize A+B bidding on this project as a means to reduce construction duration, • Jim P. requested that HNTB use Mori's Engineering as the surveyor for the project.
Action/Response • HNTB's proposal should include the task of investigating alternatives for construction phasing and displacement of tenants during construction, such as identifying
other areas in the airport that could be made available to store aircraft. • Mike E. suggested the possibility of temporarily repaving the parking lot recently used by Site Concrete
for the batch plant. • Contact Information: Mori's Enginering Mori Akhavan, P.E. 2616 Pickwick Lane Plano, TX 75093 972-816-2626 C:IDoc"mertls and 􀁓􀁥􀁴􀁴􀁩􀁮􀁧􀀦􀁾􀁰􀁬􀁥􀁲􀁣􀁥􀀮􀁁􀁄􀁄􀁦􀁓􀁏􀁎􀁇􀁏􀁜

several options to minimize the construction duration for this project. These are as follows: • A A pavement section that minimizes construction time can be used. Most notably, the lime
treated subgrade can be eliminated. • The most time-efficient pavement section would be a full depth hot mix pavement on compacted subgrade. Although more expensive, this option may
be the most viable when considering the potential of lost revenue due to the displacement of tenants. • A pavement section utilizing either cement treated base material or flexible base
material undemeath hot mix could be used. This option could be more inexpensive than the full depth hot mix option, but would take longer to construct. • Jim P. asked aboutthe possibility
of using the cold in-place recycling method. Mike H. explained that HNTB would not recommend this option, primarily because of the lack of a suitable existing pavement section that would
be pulverized and used as a base material. • Prepare and submit proposal. • Contact Bill Dyer for the meets and bounds description of the Airport property. • The proposal should include
