of a final plat APPLICANT: Town of Addison, represented by Mr. Mark Acevedo DISCUSSION: Background. Until 2000, the city did not have an accurate survey of the airport property. When
the city entered into a new management contract, the city and new manager agreed that the airport property should be surveyed and a metes and bounds description prepared. In addition,
every ground lease on the airport was surveyed and a metes and bounds description written for it. Dal-Tech Engineering was hired to perform the survey work. One of the recommendations
made during the survey work was that the airport be platted. Dal-Tech . Engineering was then hired to prepare the final plat. Proposed Plat. The Public Works staff worked closely with
Dal-Tech during the surveying process, and has no additional comments on the plat. The staff noticed that the document indicated Ron Whitehead would sign on behalf of the Town as the
owner. Typically the Mayor signs as the owner of property. Staff recommends that "Mayor Scott Wheeler" replace Ron Whitehead's name as the owner. 􀁒􀁥􀀲􀀺􀀺􀁴􀁾􀁔􀁬􀁤􀀿􀁊􀁾􀀠 Carmen

Exhibit A ADDISON AIRPORT BOUNDARY SURVEY AND BASE MAPPING SCOPE OF WORK DAL-TECH Engineering, Inc. has been asked to prepare a scope of work and an estimate of probable cost for preparing
a boundary survey and a base map of selected features of the Addison Airport property. Included in the boundary survey are locating the approximately 65 ground leases on the airport,
the through-the-fenca leases, joint use agreements, and easements affecting the property. Optionally, DTE can also produce individual lease exhibits if desired. The base map will show
all buildings, taxiways, runways, fences, and streets within or immediately adjacent to the airport boundary. In addition, utilities such as water, wastewater, storm sewer, electric,
gas, and telephone can be located at an optbnallevel of quality as explained in more detail below. The detailed scope of services to accomplish these goals is set out as follows: 1.
Gather data and perform research: A. At Town of Addison and at Addison Airport DTE staff will coordinate with Town of Addison staff in both Public Works and at Addison Airport to gather
existing documents, plans, maintenance records, electronic flies, and any other information that will aid in the preparation of the boundary survey, leasehold establishment, and base
mapping. B. At TxDOT's Aviation Division in Austin DTE staff will obtain any relevant information about Addison Airport from Charlotte Bergfeld or her designated representative in TxDOT's
Aviation Division in Austin. C. From County Courthouse Deed Records We will use an outside professional abstracting service to gather the public records research for us. Although several
of our DTE staff are very proficient in using the Dallas County Deed Records, abstracting professionals have access to easement databases that allow them to do thorough easement searches
that we are unable to do. We plan to avail ourselves of this expertise. Deliverables: DTE will prepare a document control system for the project and establish files containing relevant
documents. 􀁄􀀮􀁬􀁳􀁥􀁲􀁶􀁊􀁤􀁥􀁢􀁲􀁡􀁊􀀰􀀱􀀰􀀷􀁊􀁣􀁯􀁮􀁴􀁲􀁡􀁣􀁴􀁳􀁬􀁅􀁸􀁨􀁩􀁢􀁾􀀠A -Addison Scope.4.16.01 
2. Establish Control A. Perform GPS surveys and office processing to establish secondary control on permanent monuments. There are several high-order monuments on the airfield established
as part of the National Geodetic Survey's Primary Airport Control Station (PACS) and Secondary Airport Control Station (SACS) program. We will use these monuments as our primary control
points for the project. We will establish six additional secondary control points, which will be constructed to a Town of Addison and DTE mutually approved design at mutually agreed
upon locations. Classical static GPS surveying techniques will be used to record satellite observation files at each of the primary and secondary control points and at selected verticel
benchmarks on the airfield. Constraining the resultant network to the National Geodetic Survey monuments' data, we will perform office post-processing to determine the geodetic coordinates,
the NAD 83 (1993) Texas North Central Zone (4202) State Plane Coordinates, and the PACS NAVD88 orthometric height for each of the stations in the network. B. Run level loops as necessary
to incorporate existing vertical information. The vertical datum for the PACS I SACS points is GPS-derived NAVD88 orthometric heights. These orthometric heights are published to centimeter
precision (-0.03') and are considered to be that precise in relation to other PACS I SACS stations but not necessarily in relation to other NAVD88 known pOints in the area. Therefore,
we need to incorporate some of the "local" benchmarks to ensure that our GPS vertical model works properly. C. Prepare a report including "recovery drawings" showing each monument, its
physical location, its data, and its metadata on an individual drawing for each monument. After all of the above GPS work and leveling has been completed, DTE will compile a brief report
documenting the GPS work and the associated statistics. The report will contain "recovery drawings" showing each monument, its physical location, its data, and its metadata on an individual
drawing for each monument. Deliverables: Meet with the Town Staff to deliver and discuss the GPS Report with a "recovery drawing" for each monument. DaiservidebralOl071contractslExhibit
A -Addison Scope.4.16.01 
3. Compile graphic documents of preliminary data. A. Plot deeds, leases, "through the fence" leases, easements, joint use agreements, TxDOT information, and plan data in a digital (AutoCad
or Microstation) file. Using the data gathered in Item 1, above, we will prepare a preliminary work map compiling the known facts concerning the location and extent of airport fee ownership,
leases, utility easements, joint use agreements, aviation limitations and easements, engineering data, and other knowledge gained during the data gathering and research activities. B.
Analyze plot to identify any problem areas needing special attention and curative work. . Special attention will be paid to possible conflicts and problem areas. Those items that are
not locatable due to poor or ambiguous description will be identified for special attention. These items will be added to the preliminary work map to the degree possible for the orderly
and efficient prosecution of the fieldwork. Deliverables: the preliminary work map in CAD CAD format. 4. Prepare a preliminary report and present it to the Town of Addison Prepare a
formal report describing our findings and identifying those items from the data collected that need further attention or definition. Attend a formal meeting with the Town of Addison
staff to present the report and mutually to define "action items' for the Town of Addison and the DTE staff. Deliverables: meet with the Town Staff to present our Preliminary Report
on research. 5. Perform field surveys A. Establish three-dimensional tertiary control points for use in making boundary ties and mapping. Working from the primary and secondary control
points, DTE field crews will use GPS and conventional methods to establish tertiary control points for use in tying property comers and in mapping. Although these points will be of such
permanence as to survive the project, they will not be published formally beyond the documentation in our project files. OalSOlVldebral0107/contractslExhibit A • Addison Scope.4.16.01

B. Locate property corners and evidence of leaseholds using the preliminary work map as a guide. Our crews will use the tertiary control points to locate and tie all evidence of fee
simple boundaries and of leaseholds. Artificial monuments recited in deeds will be searched out. The evidence will be tied to the project coordinate system. /C. Locate in three dimensions
all buildings, taxiways, runways, fences, streets, and utilities within or immediately adjacent to the airport boundary. In addition to locating boundary corners, DTE personnel will
locate buildings, taxiways, crossovers, runways, fences, streets, and utilities (water, wastewater, storm sewer, electric, gas, telephone). Our involvement with utility location can
be very limited or very extensive as reflected in the four-tiered Subsurface Utility Engineering (SUE) options stated below: Quality Level D -DTE personnel can conduct "records search"
to obtain information on utilities solely from existing utility records. Quality Level C-DTE can perform a "surface visible feature survey" to locate visible aboveground utility facilities
such as manholes, valve boxes, posts and to correlate this information with existing utility records. Quality Level 8-DTE can utilize the application and interpretation ofsurface geophysical
techniques which include electromagnetic, magnetic, and elastic wave methods to deSignate the presence and approximate horizontal location of underground utilities. Quality Level A-DTE
can characterize a utility's spatial position, composition, condition, size, and other data that may be reasonably available about the utility and its surrounding environment through
its exposure by nondestructive excavation techniques, such as airlvacuum extraction. *Optianaly, DTE's level ofinvolvement for Subsurface Utility Engineering (SUE) should be determined
by the Town of Addison. Deliverables: Meet with the Town Staff to deliver copies of work notes, sketches, ASCII files, etc. OaIS.IV/debra/01 07/contracts/Exhibit A -Addison ScopeA.1S.01

6. Perform office work to process and refine field data into graphic documents. A. Download data collectors, make calculations, and perform analysis and further research to establish
property boundaries, encroachments, protrusions, leasehold limits, and easement locations. ' After the field evidence is gathered, the data will be downloaded, processed against our
control information, and imported to the project database for analysis. Inevitably, this analysis leads to a secondary level of courthouse research to clarify issues that have become
apparent. DTE will provide the services to gain these materials. Once boundary lines have been established, an analysis of the spatial relationship between boundaries and improvements
will be made to identify any encroachments or protruSions of improvements that may exist. Leases, joint use agreements, through-the-fence leases, and easements will then be harmonized
to the boundaries and the improvements, and, finally, a fieldnote description of the Airport property will will be prepared. B. Perform CAD work necessary to prepare a boundary survey
I base map presenting the results of the surveying. The graphic documents presenting the results of the survey will be prepared in CAD formal. The drawings will be "layered" to segregate
thematically related data items on the same layer to facilitate the preparation of specialized exhibits in the future. All of the data gathered will reside in this graphic environment,
and multiple drawings may be produced at the Town's request. *Opfiona//y, individual/ease exhibifs and descriptions can be prepared. Deliverables: Meet with the Town Staff to provide
hardcopies anti digital versions of the graphic documents prepared. DaI...",/debral0107/contractslExhibil A -Addison ScopeA.16.01 
7. Monument the boundaries of the airport and the leaseholds. A. Perform office work to prepare stakeout files for the field crews. Data collector files will be prepared for the crews
to use to set out the corners. B. Perform field work to set monuments (rebar with plastic caps) at all feasible boundary comers and at leasehold corners if requested by Addison Airport
staff. DTE field crews will set out 5/8" diameter 24" long rebar monuments with plastic caps at angle points in the fee simple boundary where no found monument exists. *Optionally. OTE
crews can set out the same type of monument at lease comen; ifdesired bythe Town of Addison. Deliverables: Monuments set in the field. 8. Prepare a final surveyor's report to present
to the Town of Addison. A. Prepare a final report having the following structure: 1. Executive Summary stating the project scope, objectives, and results. 2. A narrative describing the
data gathering activities, preparation of the working sketch, and the conclusions drawn from the documents gathered. 3. Minutes of the formal meeting with the Town of Addison for the
presentation of the preliminary report, the action items defined in that meeting, and the actions taken. 4.

to date and upon the completed boundary SUN<)y the following areas are needing special attention andlor curative work: 1. The intersection of Westgrove Road and Addison Road. A rum lane
was created heading east on Westgrove road at the southwest comer of the aforementioned intersection. No additional right-of-way Illking was found. The sidewalk and street appears to
be on airport property. 2. Addison Road at KeUer Springs. The jog in airport property should be adjusted to align with the new right-of-way of Addison Road 3. Deed to the property owned
by the Texas Turnpike Authority at the intersection of Keller Springs and Dooley Road. It was the understanding that this property would be returned to the City or airport. No inforroation

ADDISON AIRPORT BOUNDARY SURVEY AND BASE MAPPING SCOPE OF WORK DAL-TECH Engineering, Inc. has been asked to prepare a scope of work and an estimate of probable cost for preparing a boundary
survey and a base map of selected features of the Addison Airport property. Included in the boundary survey are locating the approximately 65 ground leases on the airport, the through-the-fence
leases, joint use agreements, and easements affecting the property. Optionally, DTE can also produce individual lease exhibits if desired. The base map will show all buildings, taxiways,
runways, fences, and streets within or immediately adjacent to the airport boundary. In addition, utilities such as water, wastewater, storm sewer, electric, gas, and telephone cen be
located at an optional level of quality as explained in more detail below. The detailed scope of services to accomplish these goals is set out as follows: 1. Gather data and perform
research: A. At Town of Addison and at Addison Airport DTE staff will coordinate with with Town of Addison staff in both Public Works and at Addison Airport to gather existing documents,
plans, maintenance records, electronic files, and any other information that will aid in the preparation of the boundary survey, leasehold establishment, and base mapping. B. At TxDOT's
Aviation Division in Austin DTE staff will obtain any relevant information about Addison Airport from Charlotte Bergfeld or her designated representative in TxDOT's Aviation Division
in Austin. C. From County Courthouse Deed Records We will use an outside professional abstracting service to gather the publiC records research for us. Although several of our DTE staff
are very proficient in using the Dallas County Deed Records, abstracting professionals have access to easement databases that allow them to do thorough easement searches that we are
unable to do. We plan to avail ourselves of this expertise. Deliverables: DTE will preparea document control system for the project and establish files containing relevant documents. Dalserv/debralO lO'7lProposa/sIAddison Scope FinalA.12.0 1 
2. Establish Control A. Perform GPS surveys and office processing to establish secondary control on permanent monuments. There are several high-order monuments on the airfield established
as part of the National Geodetic Survey's Primary Airport Control Station (PACS) and Secondary Airport Control Station (SACS) program. We will use these monuments as our primary control
pOints for the project. We will establish six additional secondary control points, which will be constructed to a Town of Addison and DTE mutually approved deSign at mutually agreed
upon locations. Classical static GPS surveying techniques will be used to record satellite observation files at each of the primary and secondary control points and at selected vertical
benchmarks on the airfield. Constraining the resultant network to the National Geodetic Survey monuments' data, we will perform office post-processing to determine the geodetic coordinates,
the NAD 83 (1993) Texas North Central Zone (4202) State Plane Coordinates, and the PACS NAVD88 orthometric height for each of the stations in the network. B. Run level loops as necessary
to incorporate existing vertical information. The vertical datum for the PACS ! SACS points is GPS-derived NAVD88 orthometric heights, These orthometric heights are published to centimeter
precision (-0.03') and are considered to be that precise in relation to other PACS I SACS stations but not necessarily in relation to other NAVD88 known points in the area. Therefore,
we need to incorporate some of the "local" benchmarks to ensure that our GPS vertical model works properly, C. Prepare a report including "recovery drawings" showing each monument, its
physical location, its data, and its metadata on an individual drawing for each monument. After all of the above GPS work and leveling has been completed, DTE will compile a brief report
documenting the GPS work and the associated statistics. The report will contain "recovery drawings" showing each monument, its physical location, its data, and its metadata on an individual
drawing for each monument Deliverables: Meet with the Town Staff to deliver and discuss the GPS Report with a "recovery drawing" for each monument. Dalserv/debmlO l071I'roposaisfAddison
Scope Final,4, 12,0 I 
3. Compile graphic documents of preliminary data. A. Plot deeds, leases, "through the fence" leases, easements, joint use agreements, TxDOT information, and plan data in a digital (AutoCad
or Microstation) file. Using the data gathered in Item 1, above, we will prepare a preliminary work map compiling the known facts concerning the location and extent of airport fee ownership,
leases, utility easements, joint use agreements. aviation limitations and easements, engineering data, and other knowledge gained during the data gathering and research activities. B.
Analyze plot to identify any problem areas needing special attention and curative work. Special attention will be paid to possible conflicts and problem areas. Those items that are not
locatable due to poor or ambiguous description will be identified for special attention. These items will be added to the preliminary work map to the degree possible for the orderly
and efficient prosecution of the fieldwork. Deliverables: the preliminary work map in CAD fonrnat. 4. Prepare a preliminary report and present it to the Town of Addison Prepare a formal
report describing our findings and identifying those items from the data collected that need further attention or definition. Attend a formal meeting with the Town of Addison staff to
present the report and mutually to define "action items" for the Town of Addison and the DTE staff. Deliverables: meet with the Town Staff to present our Preliminary Report on research.
5. Perform field surveys A. Establish three-dimensional tertiary control points for use in making boundary ties and mapping. Working from the primary and secondary control pOints, DTE
field crews will use GPS and conventional methods to establish tertiary control pOints for use in tying property corners and in mapping. Although these pOints will be of such permanence
as to survive the project, they will not be published formally beyond the documentation in our project files. Dalserv/debralO1 07/Proposals/Addison Scope FinalA 12.01 
B. Locate property corners and evidence of leaseholds using the preliminary work map as a guide. Our crews will use the tertiary control points to locate and tie all evidence of fee
simple boundaries and of leaseholds. Artificial monuments recited in deeds will be searched out. The evidence will be tied to the project coordinate system. C. Locate in three dimensions
all buildings, taxiways, runways, fences, streets, and utilities within or immediately adjacent to the airport boundary. In addition to locating boundary comers, DTE personnel will locate
buildings, taxiways, crossovers, runways, fences, streets, and utilities (water, wastewater, storm sewer, electric, gas, telephone). Our involvement with utility location can be very
limited or very extensive as reflected in the four-tiered Subsurface Utility Engineering (SUE) options stated below: Quality Level D -DTE personnel can conduct "records search" to obtain
information on utilities solely from existing utility records. Quality Level C-DTE can perform a "surface visible feature survey" to locate visible aboveground utility facilities such
as manholes, valve boxes, posts and to correlate this information with existing utility records. Quality Level B-DTE can utilize the application and interpretation of surface geophysical
techniques which include electromagnetic, magnetic, and elastic wave methods to deSignate the presence and approximate horizontal location ofunderground utilities. Quality Level A-DTE
can charecterize a utility's spatial position, composition, condition, size, and other data that may be reasonably available about the utility and its surrounding environment through
its exposure by nondestructive excavation techniques, such as air/vacuum extraction. *Optionaly. DTE's level ofinvolvement for Subsurface Utility Engineering (SUE) should be determined
by the Town of Addison. Deliverables: Meet with the Town Staff to deliver copies of work notes, sketches, ASCII files, etc. DaiservtdebralOI07IProposaIrJAddison Scope Final.4.12,O 1

6. Perform office work to process and refine field data into graphic documents. A. Download data collectors, make calculations, and perform analysis and further research to establish
property boundaries, encroachments, protrusions, leasehold limits, and easement locations. After the field evidence is gathered, the data will be downloaded, processed against our control
information, and imported to the project database for analysis. Inevitably, this analysis leads to a secondary level of courthouse research to clarify issues that have become apparent.
DTE will provide the services to gain these materials. Once boundary lines have been established, an analysis of the spatial relationship between boundaries and improvements will be
made to identify any encroachments or protrusions of improvements that may exist. Leases, joint use agreements, through-the-fence leases, and easements will then be harmonized to the
boundaries and the improvements, and, finally, a fieldnote description of the Airport property will be prepared. B. Perform CAD work necessary to prepare a boundary survey I base map
presenting the results of the surveying. The graphic documents presenting the results of the survey will be prepared in CAD format. The drawings will be "layered" to segregate thematically
related data items on the same layer to facilitate the preparation of specialized exhibits in the future. All of the data gathered will reside in this graphic environment, and multiple
drawings may be produced at the Town's request. ·Optionally, individual lease exhibits and descriptions can be prepared. Deliverables: Meet with the Town Staff to provide hardcopies
and digital versions ofthe graphic documents prepared. Dalserv/debralO107!PropOsafslAddison Scope FinnL4.12.01 
7. Monument the boundaries of the airport and the leaseholds. A. Perform office work to prepare stakeout files for the field crews. Data collector files will be prepared for the crews
to use to set out the corners. B. Perform field work to set monuments (rebar with plastic caps) at all feasible boundary corners and at leasehold corners if requested by Addison Aim..ort
staff. --...--􀀭􀀭􀀭􀁾􀀮􀀭. DTE field crews will set out 5/8" diameter 24" long rebar monuments with plastic caps at angle points in the fee simple boundary where no found monument exists.
"Optionally. OTE crews can set out the same type of monument at lease comers if desired by the Town of Addison. Deliverables: Monuments set in the field. 8. Prepare a final surveyor's
report to present to the Town of Addison. A. Prepare a final report having the following structure: 1. Executive Summary stating the project scope, objectives, and results. 2. A narrative
describing the data gathering activities, preparation of the working sketch, and the conclusions drawn from the documents gathered. 3. Minutes of the formal meeting with the Town of
Addison for the presentation of the preliminary report, the action items defined in that meeting, and the actions taken. 4. Formal surveyor's report addressing the research issues, the

Exhibit A ADDISON AIRPORT BOUNDARY SURVEY AND BASE MAPPING SCOPE OF WORK DAL-TECH Engineering, Inc. has been asked to prepare a scope of work and an estimate of probable cost for preparing
a boundary survey and a base map of selected features of the Addison Airport property. Included in the boundary survey are locating the approximately 65 ground leases on the airport,
the through-the-fence leases, joint use agreements, and easements affecting the property. Optionally, DTE can also produce individual lease exhibits if desired. The base map will show
all buildings, taxiways, runways, fences, and streets within or immediately adjacent to the airport boundary. In addition, utilities such as water, wastewater, storm sewer, electric,
gas, and telephone can be located at an optional level of quality as explained in more detail below. The detailed scope of services to accomplish these goals is set out as follows: 1.
Gather data and perform research: A. At Town of Addison and at Addison Airport OTE staff will coordinate with Town of Addison staff in both Public Works and at Addison Airport to gather
existing documents, plans, maintenance records, electronic files, and any other information that will aid in the preparation of the boundary survey. leasehold establishment, and base
mapping. B. At TxDOT's Aviation Division in Austin DTE staff will obtain any relevant information about Addison Airport from Charlotte Bergfeld or her designated representative in TxDOT's
Aviation Division in Austin. C. From County Courthouse Deed Records We will use an outside professional abstracting service to gather the public records research for us. Although several
of our DTE staff are very proficient in using the Dallas County Deed Records, abstracting professionals have access to easement databases that allow them to do thorough easement searches
that we are unable to do. We plan to avail ourselves of this expertise. Deliverables: OTE will prepare a document control system for the project and establish files containing relevant
documents. Oal..rvldebral01 071contracts/Exhibit A -Addison Scope.4.16.01 
2. Establish Control A. Perform GPS surveys and office processing to establish secondary control on permanent monuments. There are several high-order monuments on the airfield established
as part of the National Geodetic Survey's. Primary Airport Control Station (PACS) and Secondary Airport Control Station (SACS) program. We will use these monuments as our primary control
pOints for the project. We will establish six additional secondary control points. which will be constructed to a Town of Addison and DTE mutually approved design at mutually agreed
upon locations. Classical static GPS surveying techniques will be used to record satellite observation files at each of the primary and secondary control pOints and at selected vertical
benchmarks on the airfield. Constraining the resultant network to the National Geodetic Survey monuments' data, we will perform office post-processing to determine the geodetiC coordinates,
the NAD 83 (1993) Texas North Centrel Zone (4202) State Plane Coordinates, and the PACS NAVD88 orthometric height for each of the stations in the network. B. Run level loops as necessary
to incorporate existing vertical information. The vertical datum for the PACS /SACS points is GPS-derived NAVD88 orthometric heights. These orthometric heights are published to centimeter
precision (-0.03') and are considered to be that precise in relation to other PACS /SACS stations but not necessarily in relation to other NAVD88 known pOints in the area. Therefore.
we need to incorporate some of the "local" benchmarks to ensure that our GPS vertical model works properly. C. Prepare a report including "recovery drawings" showing each monument, its
physical location, its data, and its metadata on an individual drawing for each monument. After all of the above GPS work and leveling has been completed. DTE will compile a brief report
documenting the GPS work and the associated statistics. The report will contain "recovery drawings" showing each monument, its physical location. its data. and its meta data on an individual
drawing for each monument. Deliverables: Meet with the Town Staff to deliver and discuss the GPS Report with a "recovery drawing" for each monument. Dal5e!V/debralOl07/contractSlEJ<hibfi

3. Compile graphic documents of preliminary data. A. Plot deeds, leases, "through the fence" leases, easements, joint use agreements, TxDOT information, and plan data in a digital (AutoCad
or Microstation) file. Using the data gathered in Item 1, above, we will prepare a preliminary work map compiling the known facts concerning the location and extent of airport fee ownership,
leases, utility easements, joint use agreements, aviation limitations and easements, engineering data, and other knowledge gained during the data gathering and research activities. B.
Analyze plot to identify any problem areas needing special attention and curative work. Special attention will be paid to possible conflicts and problem areas. Those items that are not
locatable due to poor or ambiguous description will be identified for special attention. These items will be added to the preliminary work map to the degree possible for the orderly
and efficient prosecution of the fieldwork. Deliverables: the preliminary work map in CAD format. 4. Prepare a preliminary report and present it to the Town of Addison Prepare a formal
report describing our findings and identifYing those items from the data collected that need further attention or definition. Attend a formal meeting with the Town of Addison staff to
present the report and mutually to define "action items· for the Town of Addison and the DTE staff. Deliverables: meet with the Town Staff to present our Preliminary Report on research.
5. Perform field surveys A. Establish three-dimensional tertiary control points for use in making boundary ties and mapping. Working from the primary and secondary control points, oTE
field crews will use GPS and conventional methods to establish tertiary control points for use in tying property comers and in mapping. Although these points will be of such permanence
as to survive the project, they will not be published formally beyond the documentation in our project files. DaiselVldebral0107IC<lnlr.oIslExhiba A -Addison Scope.4.16.Q1 
B. Locate property corners and evidence of leaseholds using the preliminary work map as a guide. Our crews will use the tertiary control pOints to locate and tie all evidence of fee
simple boundaries and of leaseholds. Artificial monuments recited in deeds will be searched out. The evidence will be tied to the project coordinate system. C. Locate in three dimensions
all buildings, taxiways, runways, fences, streets, and utilities within or immediately adjacent to the airport boundary. In addition to locating boundary comers, DTE personnel will locate
buildings, taxiways, crossovers, runways, fences, streets, and utilities (water, wastewater, storm sewer, electric, gas, telephone). Our involvement with utility location can be very
limited or very extensive as reflected in the four-tiered Subsurface Utility Engineering (SUE) options stated below: Quality Level D -DTE personnel can conduct "records search" to obtain
information on utilities solely from existing utility records. Quality Level C-DTE can perform a "surface visible feature survey" to locate visible aboveground utility facilities such
as manholes, valve boxes, posts and to correlate this information with existing utility records. Quality Level B-DTE can utilize the application and interpretation ofsurface geophysical
techniques which include electromagnetic, magnetic, and elastic wave methods to designate the presence and approximate horizontal location ofunderground utilities. Quality Level A-DTE
can characterize a utility's spatial position, composition, condition, size, and other data that may be reasonably available about the utility andits surrounding environment through its exposure by nondestructive excavation techniques, such as airNacuum extraction. ·Optionaly, DTE'. level of involvement for Sub.urface Utility
Engineering (SUE) should be determined by the Town of Addison. Deliverables: Meet with the Town Staff to deliver copies of work notes, sketches, ASCII files. etc. Oalservldebra/Ol 07lcontractslEl<hib
it A -Addison Scopo.4.16.01 
6. Perform office work to process and refine field data into graphic documents. A. Download data collectors, make calculations, and perform analysis and further research to establish
property boundaries, encroachments, protrusions, leasehold limits, and easement locations. After the field evidence is gathered, the data will be downloaded, processed against our control
information, and imported to the project database for analysis. Inevitably, this analysis leads to a secondary level of courthouse research to clarify issues that have become apparent.
DTE will provide the services to gain these materials. Once boundary lines have been established, an analysis of the spatial relationship between boundaries and improvements will be
made to identify any encroachments or protrusions of improvements that may exist. Leases, joint use agreements, through-the-fence leases, and easements will then be harmonized to the
boundaries and the improvements, and, finally, a fieldnote description of the Airport property will be prepared. B. Perform CAD work necessary to prepare a boundary survey I base map
presenting the results of the surveying. The graphic documents presenting the results of the survey will be prepared in CAD format. The drawings will be "layered" to segregate thematically
related data items on the same layer to facilitate the , preparation of specialized exhibits in the future. All of the data gathered will reside in this graphic enVironment, and multiple
drawings may be produced at the Town's request. *Optionally, individual lease exhibits and descriptions can be prepared. Deliverables: Meet with the Town Staff to provide hardcopies
and digital versions of the graphic documents prepared. D.lseNidebralOl 07/conlraclslExhibit A • Addison Scope.4.16.01 
7. Monument the boundaries of the airport and the leaseholds. A. Perform office work to prepare stakeout files for the field crews. Data collector files will be prepared for the crews
to use to set out the comers. B. Perform field work to set monuments (rebar with plastic caps) at all feasible boundary comers and at leasehold comers if requested by Addison Airport
staff. DTE field crews will set out SIS" diameter 24" long rebar monuments with plastic caps at angle pOints in the fee simple boundary where no found monument exists. "Optionally. DrE
crews can set out the same type of monument at lease comers ifdesired by the Town of Addison. Deliverables: Monuments set in the field. 8. Prepare a final surveyor's report to present
to the Town of Addison. A. Prepare a final report having the following structure: 1. Executive Summary stating the project scope, objectives, and results. 2. A narrative describing the
data gathering activities, preparation of the working sketch, and the conclusions drawn from the documents gathered. 3. Minutes of the formal meeting with the Town of Addison for the
presentation of the preliminary report, the action items defined in that meeting, and the actions taken. 4. Formal surveyor's report addressing the research issues, the results of the
field work, the interpretation of the eVidence gathered, and the professional opinions drawn from that evidence. 5. The boundary survey I base map, signed and sealed, and, optionally,

perform ofrlce post-processing to determine the geodetic coordinates, the NAD 63 (1993) Texas North Central Zone (4202) State Plane Coordinates, and the PACS NAVD88 orthometric height
for each of the stations in the network, B. Run level loops as necessary to incorporate existing vertical information. The vertical datum for the PACS I SACS points is GPS-derlved NAVD88
orthometric heights. These orthomelric heights are published to centimeter precision (-0.03') and are considered to be that precise in relation to other PACS I SACS stations but not
necessarily in relation to other NAVD66 known pOints in the area. Therefore, we need to incorporate some of the 'Ioca," benchmarks to ensure that our GPS vertical model works properly.
C. Prepare a report including "recovery drawings" showing each monument. its physical location, its data, and its metadata on an individual drawing for each monument. After all of the
above GPS work and leveling has been completed, DTE will compile a brief report documenting the GPS work and the associated statistics. The report will contain "recovery drawings" showing
each monument, its physical location, its data, and its metadata on an individual drawing for each monument. Dellverables: Meet with the Town Staff to deliver and discuss the GPS Report
with a "recovery drawing" for each monument. Oelbervldebrw'01 􀀰􀀷􀀯􀁲􀀺􀀺􀁯􀁮􀁬􀀬􀀮􀁣􀁉􀁾􀁥􀀺􀁬􀀨􀁨􀁬􀁢􀁊􀁴􀀠A 􀁾􀀠AddlAon ScopeA.1B,01

filing information, sub-leased areas, etc. It will be very valuable in your efforts to complete the project. I was planning to display it during our pre-submission meeting on Feb. 14th.
However, feel free to come by anytime and look at it prior to the meeting. I also have started to acquire information on other parcels that the Town has acquired on behalf of the Airport.
This material may be very helpful. If you need any other information, please let me know. Steve Chutchian -----Original Message----From: Mauk, Thomas W [mailto:TWMauk@pbsj.com] Sent:

I Message Page I of2 Jim Pierce From: Bill Dyer [Bill.Dyer@Staubach.comJ Sent: Wednesday, January 07, 2004 6:54 PM To: Jim Pierce Subject: FW ADS Proposal This is the proposal I requested
from Alan Moore at Dal-Tech for survey work which actually inCludes three different projects. tried faxing it to you but the photos are difficult to see. I am wanting to run these by
you to make certain they appear to be in line with what a "seasoned engineer" such as yourself would expect and if the scope of work in your opinion is adequate. FYI, I have $12K budgeted
this year for survey and title work. 1) BJtYD!!!l!yjlnd Topo Survey for Keller Springs I!fl!l!!'Jty. I asked Alan to provide a proposal that would identify all that bounded by and included
within the area shown in the aerial. We need a description of a ROW for Jimmy Doolittle so a bOulJ.l1aDL of the property north of Doolittle and south of the tunnel can be defined, While
the crew was there, I asked him to do the same for """the property north of the tunneL' The two hangars within the scope of work are city owned. To my knowledge, we do not have any legal
deSCription for these buildings and their respective ram area. Once these,,;lre defined, then we can determine the vacanC land to the west of th han ars so 0 aXlwa an 0 and north of
the tunnel. Then I got ambitious and asked Alan (Since the crew IS on site) to include the two jet hangars south of Doolittle 􀁳􀁩􀁮􀁣􀁥􀁾􀀢not have a legal description for these buildings.
Cost for the described work is $6,479. We may omit the jet hangars from the scope of work to save some dollars at this time. 2) Ground"Lease T@,C,l 13A is for the Great Escape/AI Ranyak
(a.k.a. Flight Line) ground lease that needs to be amended to reflect the reconfigured boundary as a result of the Airport Parkway realignment HNTB sent Mr Ranyak a CAD file of the road
alignment so he can determine what portion ,if any, of the out parcel on the south side of the new road between Omniflight and his property he would like to include in the revised lease
premises, Proposed cost of survey is $3,082. 3) !3roJ.!Dd"Lu.s.!tIracts 5A & 58, These are not actually ground leases, they are city owned jet hangars adjacent to the proposed fuel farm.
My concem here is that we do not let the fuel farm encroach into the "lease premises" but we do not have a current legal description for these respective properties. I have on file an
old survey for the Rockwall ground leases that expired years ago but nothing current. If you look at the Dal-Tech boundary survey, it only reflects the proximity of the buildings and
does not reflect the ramp and parking areas or ingress/egress. Option A is for the jet hangars only, Option B was to encompass a larger logical block of land that needs to be surveyed
and tied to the airport boundary survey. I think for right now, in the interest of holding costs down we table this work. Subject to your input, I recommend we: a) Proceed with #2 ASAP
b) Proceed with #1 subject to Alan's estimate of savings to us for omitting the jet hangar, I suspect there will be a good cost savings to do the work while the crew is there set up
and on site. c) Table #3 until either later in the year or possibly add it to the scope of the fuel farm project when the crew is on site for that project (assuming Dal-tech will do
the survey work then), ----Original Message-From: Alan Moore [mallto:A1an@Dal-tech.com] Sent: Monday, December 29,2003 11:14 AM To: Bill Dyer Subject: RE: ADS Proposal Bill, Please accept
