reconstructing approximately 0.65 miles of the existing 4 -lane roadway section to a 6 -lane
divided facility and adding a right turn lane on Red Bud Lane. This project involves surveying,
geotechnical, environmental, public involvement, engineering analyses, and associated details
necessary to produce PS&E to a 9090 design.
The ENGINEER shall perform all work and prepare all deliverables in accordance with the latest
version of the City of Round Rock criteria.

RIGHT OF WAY DATA (Function Code 130)
Subsurface Utilitv Engineering (SUE) including utility investigations subsurface
and above ground prepared in accordance with AASHTO standards [ASCE C -I 38-
021 and Utility Quality Levels as follows.
i. Utility Quality Levels are defined in cumulative order (least to greatest) as follows:
a. Quality Level D - Existing Records: Utilities are plotted from review of
available existing records.
b. Quality Level C - Surface Visible Feature Survey: Quality IeveI "D"
information from existing records is combined with surveyed surface -
visible features (performed by surveyor). Includes Quality Level D
information. If there are variances in the designated work area of Level D
then a new schematic or plan layout, if needed, is required showing the
limits of the proposed project and limits of the work area required for this
work authorization; including highway stations, limits within existing or
proposed right of way, additional areas outside the proposed right of way,
and distances or areas to be included down existing intersecting roadways.
C. Quality Level B - Designate: Two-dimensional horizontal mapping. This
information is obtained through the application and interpretation of
appropriate non-destructive surface geophysical methods. Incorporates
quality levels C and D information to produce Quality Level B. If there are
variances in the designated work area of Level D then a new schematic or
plan layout, if needed, is required showing the limits of the proposed project
and limits of the work area required for this work authorization; including
highway stations, limits within existing or proposed right of way, additional

d. Quality Level A - Locate (Test Hole): Three-dimensional mapping and
other characterization data. This information is obtained through exposing
utility facilities through test holes.. Actual locations are tied to survey
control (performed by surveyor). Incorporates quality levels B, C and D
information to produce Quality Level A.
ii. Desienate (Ouality Level B). Designate means to indicate the horizontal location of
underground utilities by the application and interpretation of appropriate non-
destructive surface geophysical techniques, Designate (Quality Level B) Services are
inclusive of Quality levels C and D.
The UC shall:
a. As requested by the City, compile "As Built" information from pians, plats
and other location data as provided by the utility owners.
b. Coordinate with utility owner when utility owner's policy is to designate
theirown facilities at no cost for preliminary survey purposes. The Engineer
shall examine utility owner's work to ensure accuracy and completeness.
C. Designate, record and marl: the horizontal location of the existing utility
facilities using non-destructive surface geophysical techniques. No storm
sewer facilities are to be designated. A non -water base paint, utilizing the
American Public Works Association (APWA) color code scheme, must be
used on all surface markings of underground utilities (6,500 LF of
utilities).
d. Correlate utility owner records with designating data and resolve
discrepancies using professional judgment. A color -coded composite utility
facility plan with utility owner names, quality levels, line sizes and
subsurface utility locate (test hole) locations, if applicable shall be
submitted. It is understood that the line sizes of designated utility facilities
detailed on the deliverable are from the best available records and that an
actual line size is normally determined from a test hole vacuum excavation.
A note must be placed on the designate deliverable that states "lines sizes
are from best available records". All above ground appurtenance locations
must be included in the deliverable. This information shall be provided in
AutoCadd Civil 3D format. The electronic File shall be delivered on CD. A
hard copy is required and must be sealed and dated by Haiff.
e. Clearly identify all utilities that were discovered from quality levels C and
D investigation, but cannot be depicted in quality level B standards. These
utilities must have a unique line style and symbology in the designate
(Quality Level B) deliverable.
