C. Subsurface Utility Engineering for Design
1. The scope of this proposal includes Quality Levels "A", "B", "C", and "D" mapping of utilities.
The Trinity Uptown effort (approximately two-thirds (2/3) of the area) will involve Quality
Levels "B", "C", and "D". The remaining 1/3 will be performed in another phase of the
contract. This work entails an estimated utility length of 87,120 linear feet associated with the
estimated area. The Quality Level "A" effort will focus on the storm drain requirements for
approximately 15 test holes.
a. For this phase of work, two (2) maps will be provided. The first map will be depict
QL"D" information overlaid on an electronic file provided by others to show the
location of existing utilities. The second map will depict the QL"B" data acquired
showing the actual location of the utilities versus the as-built information depicted
on the first map.
b. Mapping of Utilities for two-thirds (2/3) of the Trinity Uptown area (QL"B"). This
area includes and estimated utility length of 87,120 linear feet of utilities.
ENGINEER will have a representative at a monthly utility coordination meeting.
C. The Quality Level "A"effort for the storm drain design is anticipated to require the
following test holes:
• 4 at 0'-5'deep
• 7 at 5'-10'deep
• 4 at 10'-15'deep
2. Designating Procedures(QL"B")
Prior to beginning field designating activities,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 meta I I ic/cond uctive utilities (e.g. steel pipe,
electrical cable, telephone cable). Non-metallic/non-conductive utilities will be designated using
other proven methods, such as rodding and probing. Where access is available, a sonde will
be inserted into the utility line (e.g. PVC gravity sewer pipe) to provide a medium for signal
transmission,which can then be designated using geophysical equipment.
Accurate collection and recording of designated utilities is a critical component of the SUE
process. We will utilize a method of collecting and recording survey information once the
utilities have been designated in the field. The 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 buried electric cables exist on the project, one will be
labeled E1 and the other E2, 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 surveyed point
is required. Surveyed points will typically be placed at 100-foot intervals on utilities running
parallel to the alignment and at 50-foot intervals on utility crossings. The locations will be
numbered sequentially for each individual utility line. For example, if there are 50 shots
required on buried electric line E1,the points will be numbered E1-1 through E1-50.
Preliminary field sketches depicting the designated utilities will be prepared for use during
subsequent surveying activities. These sketches will also be used to check the survey
information for completeness and accuracy.
3. Locating Procedures(QL"A")
We will utilize its utility designating marks to layout the test-hole locations. We will utilize non-
destructive vacuum excavation equipment to excavate test holes at the required locations.
Once each utility is located, we will record the utility type, size, material, depth to top and
general direction. Each test hole will be assigned a unique ID number and will be marked with
rebar/cap, nail/disk, or chiseled X, as appropriate. The test-hole ID number and other pertinent
utility information will be placed at each test-hole location.
Test-hole excavations will be backfilled with appropriate material and the original surface will be
restored. When test holes are required under pavement, we will use a 10"core drill to prevent
spalling. The test hole will be backfilled with clean, dry backfill and finished with like material,
(concrete or asphalt). The backfill will be compacted in lifts by mechanical means to prevent
future settlement.
Test-hole locations will be added to the previously mentioned field sketches for use during
surveying activities.
4. Deliverables
SUE plans depicting the type and location of the designated utilities for the specific Quality
Level. The size of each utility will also be presented on the SUE plans where test-holes have
been completed. Where no test-holes have been completed, the size and material type will be
provided only if the information is indicated on available record drawings.We will produce a
summary sheet containing test hole field notes. A test hole data form will be prepared for each
test hole following receipt of coordinate and elevation information from the surveyor. SUE plans
depicting designated utility information will be revised to include test hole locations. We will
codify franchise utility information into one record document(City Specs in GIS format)

4. Brennan Avenue Drainage Outfall Hydrologic and Hydraulic Calculations
a. This work is performed on behalf of the City of Fort Worth at the request of the USACE,
TRVA Partners, and CDM to provide culvert sizing information for the outfall channel
downstream of the City of Fort Worth Brennan Drop Off Station. The current open
channel is proposed for enclosure to provide additional fill locations for excavation from
the TRVA Samuels North mitigation site. The City requested that culverts be designed
to City Standards, including 100-year capacity in the enclosed culvert. The City also
indicated that some portion of the flows from the neighboring drainage basin to the east
overtop the topographic high and should be included in the design calculations. This
analysis will quantify the amount of interbasin transfer and provide design sizes to CDM

sewer, storm water, electric, natural gas, and franchise utility alignments.
2. Obtain and review existing environmental data maintained by the USACE, TRVA, Tarrant
Regional Water District, and other sources for the Bypass Channel/Bridge Corridor area.
3. Develop a work plan for a Phase II environmental site assessment(ESA)of proposed utility
locations for storm water, electric, natural gas, and franchise utility alignments that are not
located within rights-of way for water/sanitary sewer utilities. Sample locations will be selected
so that they do not overlap with other investigations that have been performed by other entities
assisting the TRVA with environmental investigations. Submit the work plan to City for review
and approval prior to initiating field work.
4. Conduct limited Phase II ESAs. The purpose of the limited Phase II ESAs shall be to identify:
a.Potential subsurface contamination that might require protection of utility lines.
b.Potential construction worker safety requirements related to the presence of
contaminated soils.
c.Potential waste classification and disposal requirements for excess spoils generated
during construction of utilities.
Samples will be collected on approximately 100 to 150 foot spacing depending upon the
presence/absence of data from previous environmental investigations. Samples will be
analyzed for the following chemicals of concern:
i. Volatile organic compounds.
ii. Semi-volatile organic compounds.
iii. Total petroleum hydrocarbons
iv. Priority pollutant metals.
Based on available information,there are approximately 20,000 linear feet of utility alignments
that will require sampling. Based on this information, this scope includes effort for 12 days of
sample collection for one two-person field crew, 12 days of effort by a direct-push drilling
subcontractor utilizing a direct-push drill rig, and laboratory analysis of approximately 150
samples in the Bypass Channel/Bridge Utility Corridor.
5. Develop a Contaminated Soil/Water Management Plan including plans and specifications for
excavation, handling, transportation, and disposal of contaminated soils or waters that might
be excavated during utility construction projects. Completion of this task will require
coordination with TRVA representatives to implement contaminated soil/water handling
strategies that have been developed for the project(i.e. stockpiling of contaminated materials
at a central location for later disposal).
