From: Rob Cohen, Director of Public Works
Item 4C
Subject: Approve an Engineering Services Agreement (ESA) with
Dannenbaum Engineering Company, LLC (Dannenbaum) to
provide engineering design and construction services for
mobility improvements at the intersection of FM 1709 and
Pearson Lane in an amount not to exceed $160,000.
Action
Requested: Approve an Engineering Services Agreement (ESA) with
Dannenbaum Engineering Company, LLC (Dannenbaum) to
provide engineering design and construction services for mobility
improvements at the intersection of FM 1709 and Pearson Lane in
an amount not to exceed $160,000.
Background
Information: Pearson Ln is currently a two-lane undivided arterial north of
Southlake Blvd (FM 1709) and a two-lane undivided collector south
of Southlake Blvd (FM 1709). In the current configuration, the
intersection experiences significant congestion during peak hours.
The level of service is anticipated to be reduced with the continued
development along FM 1709 and Pearson Lane. The project will
consist of adding a left -turn lane for the northbound and
southbound approach of Pearson Ln at FM 1709. Improvements
will increase mobility, reduce congestion, enhance traffic and
pedestrian safety, and improve connectivity. Additional
improvements include signal timing changes and pedestrian
accommodations such as curb ramps, push buttons, and sidewalks.
The improvements at the intersection will be a joint project with the
City of Keller.
A future Interlocal Agreement (ILA) with the City of Keller will result
in Keller funding 25% of the total cost for Improvements.
Improvements for the intersection were identified as part of the
2030 Mobility Master Plan and reaffirmed via Intersection Capacity
Analysis performed by Kimley Horn, dated November 2017.

improvements within the existing pavement of both FM 1709 and Pearson Lane.
Right of Entry: The Surveyor will coordinate with the project Engineer to obtain right -of -entry (ROE) for mapping
on this project. These services will be provided on the Surveyor's behalf prior to starting.
Texas811 OneCall Coordination: Prior to commencing any topographic fieldwork, the Surveyor will submit a
utility locate request for the project limits to Texas811 (formerly Texas Excavation Safety System, Inc.) online at
www.Texas8ll.org or by telephone at 811 or 800-344-8377. Marks set by Texas811 will be shown on our survey.

names and property address. City and County boundaries will be shown where applicable. Property owner and
business names will be shown on the survey.
Roadways and Improved Surfaces: Roadways, driveways, alleys and sidewalks will be located and identified on
the survey. Existing width and composition of improved surfaces will be shown on the survey.
• Existing pavement markings and signage will be identified on the survey.
• Traffic signal bases, mast arms and control boxes will be shown on the survey.
Surface Drainage Features: We will locate and tie top, toe and flow lines of existing swales, channels and creeks
with the project limits. Our survey will locate headwall and wingwalls and denote number, size, material type,
flow line and top of pipe elevation for culvert conduit(s).
TxDOT Maintained Roadways: Our survey will include an alignment(s) that coincides with the original Texas
Department of Transportation (TxDOT) alignment stationing for those roadways within our project limits
maintained by TxDOT. The Surveyor will provide an electronic PDF of TxDOT documents used to determine the
original station. TxDOT monuments will be located for portions of the project located on or adjacent to TxDOT
maintained facilities.
Trees, Shrubs, Landscaping and Irrigation: We will locate trees 4" or larger in diameter, shrubs and landscaping
features and provide identification notes accordingly. We attempt to provide tree common name and caliper as
measured approximately four feet off the ground. Major tree and brush lines will be delineated on the survey.
Existing visible irrigation structures and planters will be located on this survey.
Methods and Precision
Basis of Control: Local municipal geodetic control, if available, otherwise the Allterra-VRS GPS system will be used
to establish our horizontal and vertical values.

been approved by the owner/client.
SUBSURFACE UTILITY ENGINEERING
The scope of this proposal includes Quality Level "B" SUE. Utilities to be designated include gas, telecommunications,
electric, traffic signals, storm, water and sanitary sewer. Designating will be performed within the following limits as
indicated in Exhibits "A".
Quality Level B (QL"B") - Two-dimensional (x,y) information obtained through the application and interpretation of
non-destructive surface geophysical methods. Also known as "designating" this quality level provides the horizontal
position of subsurface utilities within approximately one foot.
Designating Procedures
Prior to beginning field designating activities, TRG's field manager will review the project scope of work and available
utility records. Once these initial reviews are complete, the field manager and technicians will begin designating the
approximate horizontal position of known subsurface utilities within the specified project limits. A suite of geophysical
equipment (electromagnetic induction, magnetic) will be used to designate metallic/conductive utilities ( e.g. steel
pipe, electrical cable, telephone cable). TRG will establish routine/ordinary traffic control ( cones and free standing
signage, etc.) whenever required as part of standard pricing. If non -routine traffic control measures are required
(barricades, flag person, changeable message board, etc.), these services will be considered extra.
Accurate collection and recording of designated utilities is a critical component of the SUE process. TRG utilizes a
proven method of collecting and recording survey information once the utilities have been designated in the field.
TRG's field manager will produce detailed sketches depicting each utility as well as relevant surface features such as
roadways, buildings, manholes, fire hydrants, utility pedestals, valves, meters, etc. Each utility will be labeled with a
unique ID code. For example, if two different water lines exist on the project, one will be labeled WI and the other
W2. Paint and pin flags will be used to designate the utilities in the field. A labeled pin flag or paint mark will be used
to mark each location where a survey shot is required. The locations will be numbered sequentially for each individual
utility line. For example, if there are 10 shots required on water line WI, the points will be numbered WI -1 through
WI -10.
Quality Level A (QL"A") Test Holes are included in the scope at the quantity and depth as outlined on the attached Fee
Estimate. Actual number and depth may vary and will be billed at contracted rate shown on the Fee estimate (plus
subconsultant markup).
