Please be advised of the following information for purposes of your Qualifications Documents, and
acknowledge receipt of same in the cover letter that accompanies your statement of qualifications. This
Addendum is hereby made a part of the request for qualifications of the above referenced project. All other
requirements of the original advertisement shall remain in effect in their respective order.
General Information.
The following items are included in this Addendum:
Questions and Answers:
1. Q: Does the COVER LETTER, TABS, TABLE OF CONTENTS, COVERS, or FORMS count in the
25-page limit?
A: The COVER LETTER, TABS, TABLE OF CONTENTS, COVERS and FORMS do NOT count in
the 25-page limit.
2. Q: If we currently do not hold a MBE/DBE cert in North Carolina, what other certifications are
acceptable?
A: The consultant must to be listed as a DBE in the NCDOT database. MBE certification does not
count towards the goal, only DBE.
3. Q: If a North Carolina certification is mandatory, could our firm be recognized while waiting for
application approval?
A: The firm must be certified as a DBE by the NCDOT when submittals are due.
4. Q: The first paragraph of the “Agreement for Professional Services” ends with the phrase “[INSERT
COMPANY NAME AND CORPORATE DESCR.] with offices in Charlotte, North Carolina,
(“Company”).” Are we correct in assuming that the Company’s office location will be changed as
appropriate and that a Charlotte business address is not required?
The second “whereas” in the agreement identifies “design and construction services.” Are we correct
in assuming that this phrase will be modified as appropriate to reflect the general services to be
provided under this project?
A: Specific company information, regardless of company location, and project information will be
modified once a firm is selected. In addition, Article #3 of the contract may be modified depending
on how the fee detail is structured.

6. Q: Part 150 requires noise contours and analyses for two time frames: (1) the year of submission
and (2) a forecast case that is at least five years from the year of submission. Will the Airfield
Capacity Enhancement Plan (ACEP) forecast cover these time frames? If some enhancement to the
forecast is required to meet Part 150 requirements, will the ACEP consultant or the Part 150
consultant perform that enhancement?
A: The ACEP will produce forecasts for 10 and 20 years into the future. Any enhancements or
alterations to the ACEP forecast required to complete the NEM Update will be done by the NEM
Update consultant.
7. Q: Is a completed Exhibit F, Section 2 “Buy American Certificate” required for this submission, since
the Noise Exposure Map Update project does not involve a “total facility,” “equipment,” or

Subject/Title
CAD-GIS Data Standard Guidelines
Date Effective
Revision Date Effective
Version 5.1 March 1, 2011
PURPOSE
CAD-GIS Guidelines leverage investments in survey accurate data produced in Computer-Aided Design (CAD) software
applications to update and maintain data in the City of Charlotte’s (City) Geographic Information System (GIS). These
guidelines:
1) Provide a flexible and consistent guide for compiling CAD drawing features found in land development plans and
other internal and external sources so that they can be used as source data to update and maintain the City’s GIS
data,
2) Blend with existing City business processes for land development, planimetric/topographic mapping, and capital
improvement projects, and
3) Make it possible to merge digital mapping of CAD data with GIS by developing conversion methodologies or
translator software processes between spatial and attribute features in both systems.
SCOPE
These guidelines are established for CAD data created or received by the City of Charlotte that can be used to support
City GIS data. CAD-GIS Guidelines are intended for use by:
1) Architects, surveyors, and engineering firms that submit land development plans to the City for review;
2) Internal sources and contractors working on City capital improvement projects;
3) Topographic mapping contractors; and
Page 4 of 13
4) Others who originate CAD data for the City.
The guidelines assume survey accurate or source data is prepared using some type of CAD software and can
be represented in GIS format. The following CAD file documents types, supporting business processes, and
associated KBU and KBU Divisions responsible for receiving these CAD files are identified in table 1.

BACKGROUND
The City of Charlotte has been using geographic information system (GIS) technology since 1988 to store, manage, and
maintain spatially enabled data to facilitate delivery of citizen services. Data created in computer aided design (CAD)
software is currently submitted as hard copy printed format, electronically as PDF, or as drawing (.dwg) files and should
be used to maintain GIS data. A consistent receipt of CAD data in a standardized .dwg will improve spatial data
maintenance. Implementation of CAD-GIS Guidelines, where no contract or ordinance exists, has been unsuccessful.
This is a gap in the GIS data workflow. CAD-GIS Guidelines are therefore needed to ensure the quality and content of
CAD data will be useful for maintaining the GIS database, will enhance data positional accuracy harvested from .dwg
files.
DEFINITIONS
Term
Definition
CAD
Computer Aided Design - is the use of computer technology for the process of design and design-documentation. CAD software
applications are used to prepare survey and engineering drawings. The City’s preferred CAD software is AutoCAD from Autodesk.
CLDSM

standards, budgets, and priorities to meet the City’s business needs and advance comprehensive citizen service.
GIS
Geographic Information System – A GIS integrates hardware, software, and data for capturing, managing, analyzing, and displaying all
forms of geographically referenced information. The GIS developed by the City of Charlotte is used by staff to provide information on the
geographic location and characteristics of natural or constructed features and boundaries on the earth. The City’s preferred GIS
software is ArcGIS from ESRI.
NCBELS
North Carolina Board of Examiners for Engineers and Land Surveyors – the board is responsible for the administration and regulation of
the professions of engineering and land surveying in North Carolina.
GUIDELINES
The City of Charlotte advocates CAD-GIS Guidelines to support the maintenance of its GIS data. Guidelines
are intended to be consistent with existing City standards. If conflicts are found staff are encouraged to submit
their concerns to the City GIS Enterprise Team (GET). Where any potential redundancy or conflict exists
between these guidelines and existing City or business standards stated within a contract or otherwise
specified by the business, please adhere to the existing specified standards. Otherwise, it is encouraged but
not required that digital CAD files submitted to the City adhere to the following format.
File Submission
CAD files may be submitted to individual City KBU consistent with current processes or per current contract
requirements.
File Formatting
Component
Definition
File Format
1) The digital file format should be AutoCAD drawing files (.dwg) format, unless otherwise specified by the
recipient KBU.
2) Microstation users should combine reference files to one AutoCAD .dwg.
3) ASCII or Text Files with additional information (i.e. attribute information) about the drawings or drawing
features should be comma delimited and may be submitted as separate files in PNEZD format (Point
number, Northing, Easting, Zenith, and Description).
AutoCAD
Version
1) Drawing files are preferred in AutoCAD Version Release 2007 or greater.
2) Drawing files produced in AutoCAD Version Release 2010 are presently not compatible with the City GIS
and should be resaved to AutoCAD 2007.

Sheet Naming
Drawing
Coordinates
1) CAD files submitted electronically to the City must be in accordance with North Carolina Board of
Engineers and Land Surveyor (NCBELS) requirements (21 NCAC 56.1103).
CAD drawings are requested for submittal using the naming conventions consistent with those found in:
1) the Charlotte Land Development Standards Manual
2) with other naming conventions requested by the recipient KBU; or
3) with those specified by contract.
It is essential that the geodetic control used be referenced and clearly described in the plan drawing.
1) Submit files in the North Carolina State Plan Coordinate System, Zone 3200, in survey feet using North
American Datum 1983 (NAD83).
2) City of Charlotte Subdivision Ordinance require plans to be tied to the NC Grid.

Drawing File Content
Content
Submission
Preparation
Description
Steps recommended prior to submission:
1) Turn all layers to visible
2) Zoom to the drawing extents to confirm no drawings features exist beyond the plan view extents
3) Purge any unwanted CAD layers
4) Copy to a new drawing using “Copy with Base Point” (0,0,0)
5) Paste contents into a new drawing using clean or blank drawing template (ACAD.DWT)
6) Create a file and save in AutoCAD 2007 file format
Map Precision
1) The digital version of a map should be of high precision in accordance with requirements of the North
Carolina Board of Examiners for Engineers and Surveyors (NCBELS).
Layer Names
1) Existing and proposed features should be distinguished by using separately named layers (i.e.
EX_P_PARCELBOUNDARIES (is this supposed to have the “_P_”?) for existing parcel lines, P_PARCELBOUNDARIES for new).
2) The choice of layer name used for each drawing feature should remain at the discretion of the customer
for the present time.
3) Drawing features should include separate layers names for features specified in the table included as
Appendix A – Digital Submittal Layer Guidelines.
4) Layer naming requirements should remain at the discretion of the customer for the present time unless
using a City supplied drawing template. Those seeking further guidance on layer naming should consult
the City AutoCAD Design Manuals of Engineering and Property Management (E&PM), CharlotteMecklenburg Utilities (CMU), or the National CAD Standard for suggestions.
Text
1) Any features or text that is not organized into specified layers may be placed into the miscellaneous feature layer and miscellaneous
annotation layer.
2) Text labels should be used in standard fonts that can be read without third-party software.
3) No annotation text should be included in any feature layer and no features should be included in any text layer.
4) Text and miscellaneous linework (leader lines) should be placed on unique layers (text layers) separate from the features they
annotate.
5) Text labels and text leaders should be placed in the drawings in such a manner so as not to break continuity of line or polyline of
features to which associated (see points, lines, and polygons).
Color
1) Drawing layer line color preferences should remain at the discretion of the customer for the present time.
Symbology
1) All data should be completed using standard symbol sets/graphics that require no “third-party” software unless otherwise allowed by
the recipient City KBU.
Feature Types
1) Feature types include points, lines and polygons.
2) Similar features types cannot be placed on multiple layers and different feature types should not be combined onto the same layer.
3) Features other than those thematically defined by the individual layer name/description should not be included in that layer.
Blocks
1) When using CAD drawing blocks, do not store text, polylines, or points as part of the block.
External
References
(XREF’s)
1) References to external CAD layers should be removed and the referenced information included directly in
the plan drawing submittal for layers identified in Appendix A that contain new (non-existing) features
important for updating GIS data.
Page 8 of 13
Feature
Topology
1) Digital linework should be topologically clean meaning geometrically continuous and boundaries should be closed with no
“undershoots” or “dangles” where boundaries intersect.
2) The digital linework should not include gaps or overlaps between features.
3) Traverse features should be snapped closed at intersections.
4) All unique features should be closed (i.e. no undershoots or dangle) if they represent areas and continuous (i.e. no gaps or
overlaps) if they represent lines.
5) Polygons should be digitized clockwise.
6) Polylines and Lines should be of a continuous line-type, such that each individual line (i.e. pipe) feature is only broken at the ends
where a node (i.e. structure) is located.
7) Polyline type features such as parcel boundaries, subdivision boundaries, building footprints, etc. should be snapped closed, even if
this means lines may need to be duplicated on more than one layer.
8) Where a polygon reference feature extends beyond the edge of the plan, the property boundary (repeated on the polygon feature’s
layer) may be used to close the polygon. Alternatively, include partial polygons (parcel boundaries) shown for reference on an
unnamed separate layer so that they are not selected during conversion to GIS.
9) All edges on polygon features should be snapped together at the vertices.
10) All point features should be entered using standard point/node symbols so that 3rd party software is not
required.
Guidelines by Feature Theme
Theme
Definition
Transportation
1) Street centerlines lines should be snapped together at intersections.
2) When submitting plans that include surveyed ground surfaces, the following options are available:
a. Separate ASCII text file containing all elevations points delivered in a single comma-delimited ASCII
text file with each line of the file containing values for a single point as follows – Easting, Northing,
Elevation.
b. Elevations can also be annotated on a separate annotation defined layer.
Storm Water
Features
1) Storm water line and point features should be digitized with proper directionality: lines should be drawn
from the uphill node to the downhill node or flipped after the lines have been digitized.
2) Each individual feature class should be differentiated and each appurtenance type should be differentiated
(i.e. different pipe sizes) on separate layers.
3) When submitting plans that include surveyed ground surfaces, the following options are available:
a. Separate ASCII text file containing all elevations points delivered in a single comma-delimited ASCII
text file with each line of the file containing values for a single point as follows – Easting, Northing,
Elevation.
b. Elevations can also be annotated on a separate annotation defined layer.
4) Curves may be digitized with enough vertices to capture the curve geometry, but they should be single,
continuous lines. Curves or arcs may also be used to designate curved pipe.
5) All storm water lines should be continuous, with pipe endpoints snapped to each other at endpoints
(nodes).
Cadastral
Features
1) Subdivision / project parcels, and easements (public, private, greenway, utility) should be delivered
as closed polygon features within their own layers (i.e. not closed with the subdivision/project
boundary).
Page 9 of 13
Sewer Features:
1) Sewer Lines and Sewer Taps should be digitized with proper directionality: lines should be drawn from the uphill node to the
downhill node or flipped after the lines have been digitized.
2) All tangents between sewer manholes should be drawn with a single line. Lines should not continue for more than one tangent.
3) All tangents should be snapped at endpoints intersecting at the exact center of the manhole. No gaps should exist between
tangents.
4) Manholes should be symbolized consistently with an insert centered and snapped on the tangent endpoints.
5) Sewer tap locations should be snapped to the sewer tangent and accurately placed.
6) The sewer tangents between the manholes should NOT be broken by the tap locations.
7) Sewer manholes, cleanouts, appurtenances or any other item requiring elevations should be annotated on a separate annotation
defined layer.
Utility Features
Water Features:
1) Water lines should be digitized with all straight-line pipes consisting of only two end points. Straight-line pipes will begin and end
at the following features (nodes): hydrants, valves, meters, pumps, tees, crosses, and valves. Polylines should be used wherever
a water line contains elbows or bends (i.e., when the line does make a straight run from node to node). The water lines should be
mapped according to the curvature of the road right-of-ways and not be broken with the exception of a node. Bends are not
considered nodes and are to be mapped using vertices. Please try to limit the number of vertices drawn.
2) Curves may be digitized with enough vertices to capture the curve geometry, but they should be single, continuous lines. Curves
or arcs may also be used to designate curved pipe.
3) Hydrants should be shown in their true, surveyed location, and should be connected to the water main via a valved fire hydrant
line.
4) All water lines should be continuous, with pipe endpoints snapped to each other at endpoints (nodes).
5) Stud fittings should be drawn to differentiate end-of-lines from lines that extend beyond the extent of the drawing. Stud fittings
should be drawn for lines that are to be permanently capped when the project is complete, not for lines that are temporarily
capped pending inspection.
IMPLEMENTATION CONSIDERATIONS
The CAD-GIS Guidelines will serve as a resource to all new investments after its adoption. The Project
Alignment Resource Team (PART) will be responsible for initiating procedures with the GET for new
investments that flow through the Technology Project Evaluation Team (TPET) process to encourage
compliance.
COMPLIANCE
The CAD-GIS Guidelines will be reviewed and updated annually. The GET shall convene a workgroup
annually for review of changes to monitor state, to advance or retract guidelines, for ensuring continued
applicability and compliance with existing or planned City business standards including:
1)
2)
3)
4)
