INTRODUCTION
AECOM will provide professional services to the City of Fort Collins (City) for the Mail Creek Ditch Siphon
Overpass located at the Union Pacific Railroad (UPRR) approximately 1 mile south of Harmony Road
along the Power Trail in Fort Collins, Colorado. The goal of the project is to design a pedestrian bridge
over the UPRR tracks to provide safe, multi-use trail connectivity. The pedestrian bridge will provide a
safe route for trail users to cross over the UPRR instead of using unprotected “social” crossings in the
area. The project will include construction of multi-use trail approaches to the bridge and must provide
connection to the Power Trail that runs parallel to the railroad tracks. The trail design also includes
extending the trail along the Mail Creek Ditch to the east and tying into Timberline Road.
The general scope of work of the Preliminary Design (PD) Phase is to complete preliminary design plans
and a cost estimate. The project will also include support to the City for railroad coordination, public
outreach, coordination with the ditch owner, and environmental compliance.
SCHEDULE
The anticipated work schedule is below. The work schedule will be refined after the Notice to Proceed.
· Preliminary Design (6 months)
· Final Design and Construction Plans: Not included with this scope
· Construction Support: Not included with this scope
AECOM will submit the preliminary design plans and estimate as outlined in this scope document, for
review by the City.

PROJECT UNDERSTANDING
AECOM is looking to continue SUE services as part of Pedestrian Bridge Project in Fort Collins, Colorado. It is understood that AECOM
desires to comply with the requirements outlined in SB-167 and perform an ASCE-38-02 compliant SUE investigation that is signed and
sealed by a Professional Engineer. To accomplish this project goal, accurate and comprehensive mapping of the existing utility system is
needed. T2 UES, Inc.’s unique understanding of the impact that Colorado State Senate Bill (SB) 167 has on the successful development of
engineering design projects enables our company’s services to play a vital role in the planning, design and construction of transportation
projects of this size and complexity. T2 UES, Inc.’s project approach takes this recent legislation into account and ensures compliance with
the law.
The team will utilize the CI/ASCE 38-02 standard for collecting and depicting the existing utilities and build the highest quality utility map
available. This process will include an iterative field investigation and drawings that are signed and sealed by a Professional Engineer in
accordance with all of the requirements outlined in the new State Law.
T2 UES, Inc.’s general workflow to our approach is outlined below and includes weekly updates for the entire project team:
1. Meet with the design team to review the project’s scope and expectations;
2. Perform records research (Quality Level D);
3. Perform geophysical investigation (Quality Level B designating);
4. Perform survey of utility markings placed by our designators;
5. Complete utility mapping with depictions as outlined in the ASCE 38 standard;
6. QA/QC of our investigative findings based on existing records, maps and as-built information;
7. Review the investigation findings with the design team and project stakeholders;
8. Complete QLA Test Holes as requested by the design team (if requested);
9. Provide mapping of the completed utility investigation findings – signed and sealed by a licensed engineer.
LIMITS OF INVESTIGATION
MAIL CREEK DITCH SIPHON
o The SUE investigation will be limited to the area shown below (BLUE) and require coordination and permitting with the RR.
o The eastern limit will be the westernmost edge of pavement of S. Timberline Road.
The results of this utility investigation and any survey work performed in conjunction with the investigation will be tied to the project
datum as specified by the client and existing survey grade control points will be provided to T2 UES, Inc. for their use if it is available.
In the absence of direction from the client or a control diagram, T2 UES, Inc. will use a Local Coordinate System of its choosing and
either local or NAVD88 vertical datum.

Mail Creek Ditch Siphon SUE Investigative Limits (4/22/2020).
PROJECT APPROACH
T2 UES, Inc. will complete a SUE mapping investigation in accordance with the CI/ASCE Standard 38-02: Standard Guideline for the
Collection and Depiction of Existing Subsurface Utilities. ASCE 38 provides a nationally recognized, standard guideline for the collection and
depiction of existing subsurface utility data. The quality level provides a professional opinion of the quality and reliability of the utility
information. The four quality levels are as follows:
Quality Level D (QLD): Record research of existing subsurface within the project limits by contacting each utility owner and obtaining
their available facility records. This process will substantiate necessary records that will be obtained and the mapping of untraceable
(nonmetallic buried without trace wire) utilities that do not meet Quality Level C or B specifications. QLD mapping is based on information
obtained from record drawings and includes utility type, ownership, size and material composition.
Quality Level C (QLC): Inclusive of a QLD effort, the project team will provide QLC mapping of existing untraceable subsurface utilities
by correlating surveyed surface evidence to the QLD utility records to obtain the utility location. QLC mapping includes utility type,
ownership, size and material composition based on available record information. As part of this task, the project team will complete
structure diagrams and review for overall mapping and completeness of the system.
Quality Level B (QLB): Involves the use of QLC and QLD methods of utility investigation and the use of surface geophysical techniques
under the direction of a Professional Engineer licensed in the State of Colorado to determine the existence and horizontal position of
underground utilities with a precision of three inches from the exterior sides of the line, facility or system. This activity is called
“designating.” The information obtained in this manner is surveyed to project control. Two-dimensional (2D) mapping information is
obtained.
Quality Level A (QLA): Involves the use of QLB, QLC and QLD methods of investigation, plus the use of minimally intrusive excavation
methods at critical points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size,
condition, material and other characteristics. The excavation and data documentation activity is called "test holing" (sometimes called
Potholing). It is the highest level of utility certainty presently available. When surveyed and mapped, precise plan and profile information
is available for making final design decisions.
T2 UES, Inc.’s general approach is to perform a QLB investigation using all available geophysical means and methods to identify the location
of the subsurface utilities within the project limits. Where QLB data is not able to be obtained, the utility will be show at QLC or QLD depending
on available information and surface features.
The scope of services identified below provide for QLB mapping in the designated areas.
The following tasks outline in detail our approach to the services to be rendered.

SCOPE OF WORK
A Professional Engineer licensed in the State of Colorado (Consultant) shall conduct, document, stamp and seal a Subsurface Utility
Engineering (SUE) investigation of the project area to determine existing utility conditions within the project limits. As part of the SUE
investigation for this project the Consultant will work on the following tasks:
Utility Records Research
The Client shall perform the following activities as part of their research effort on this project:
Conduct a full reconnaissance and utility records research to aid in the identification of Utility Owners that may have facilities on,
or be affected by, the SUE project.
Collect all applicable utility facility records available through Utility Owner(s), such as one-call notification, service maps, as-built
drawings, standard drawings, service plats, construction plans from prior projects, local government or Agency permit exhibit
drawings, and oral histories gained through interviews with Utility Owner officials and authorities.
Make every effort to ascertain records verifying the presence of both active and inactive underground facilities.
Compile a list of all utility companies contacted for information. Note information received with contact information for each
response and note non-response if applicable.
Attempt to identify all known and unknown utilities, except as noted above, within the project area at QLB and depict those utilities
at the actual achieved utility Quality Level.
Perform QLB Investigation
The Utility Investigation requirements are to meet Quality Levels A and/or B, as required under CI/ASCE 38, and to satisfy the horizontal
designation precision defined by the project.
Utilize geophysical utility locating techniques to determine the true horizontal position of conductive utilities within the project area.
The project team will provide QLB mapping of existing traceable (metallic or nonmetallic buried with trace wire) subsurface utilities
utilizing a variety of geophysical locating equipment to detect, verify and designate the location of subsurface utilities from above
ground. Once designated (horizontally positioned), verified utilities are marked using appropriate pink paint and flagging which is
the standard industry color for temporary markings. This field information is then surveyed and mapped into a digitized AutoCAD
file compatible with the project design files.
T2 UES, Inc. will utilize a full suite of geophysical equipment appropriate to existing site conditions for locating the type of utility
being investigated. Utilities that were not identified by the records research will be termed “undocumented”.
T2 UES, Inc. will use a complimentary suite of geophysical tools in an attempt to determine the location of undocumented utilities
and will not be responsible for finding all undocumented utilities.
T2 UES, Inc. will use inductive scanning techniques in critical areas to assist with verifying the presence of any conductive
undocumented utilities. QLA Test Holes may be necessary to determine undocumented utilities in areas of potential conflicts and
will be discussed with the Client prior to being completed.
GPR NOTE: The degree of success of a GPR investigation is based entirely on the composition of the soils and the depth and
scale of subsurface targets. Electrically non-conductive soils, such as quartz sands, typically allow for the study of phenomena to
depths greater than 15 feet. Electrically conductive soils, such as clay, moist silt or saline soils, typically preclude the investigation
of targets deeper than 3-6 feet. A determination of a maximum attainable depth of investigation requires on-site resistive site
calibration of the GPR equipment. Subsequently, due to the unknown receptiveness of specific site soils to the passage of radar
energy, conclusive results cannot be guaranteed from ground penetrating radar.
o QLB will be attempted on all mainline utilities included within T2 UES, Inc.’s geophysical investigation, with the exception of
sewer and storm drain which will be shown at QLC.
o Individual utility services to homes and buildings will include water and natural gas only if they are easily identifiable and
serviced directly from the ROW. Underground storage tanks (USTs), septic fields, traffic loop systems, thrust blocks, drain
tiles, irrigation channels/gates/valves/piping/headwalls, and landscape irrigation (both public & private) may require advanced
geophysical methodologies that can be discussed, but are excluded from this proposal.

o Invert information and, where possible, pipe size/material for the sewers will be collected at MH’s/CB’s where accessible from
the surface and shown on the drawings as appropriate. The alignment of the sewer pipes will be shown on the drawing based
on a combination of record information received, results of the invert investigation, surveyed MH’s/CB’s and professional
judgment. Collection of cable/conduit measurements and vault/structure dimensions will be documented and mapped into the
utility base file. If confined space entry is required to obtain information of offset or excessively deep pipes, extra costs will be
incurred and will be discussed with the client in advance. If chambers are full of water or confined space entry is required
extra costs will be incurred and will be discussed with the client in advance.
o Overhead utility lines will be shown as a singular line running pole to pole if they impact the designated segments. Ownership
& connections will not be noted. Pole diagrams are not included.
DELIVERABLES – QLD, QLC, QLB
Utility Research Record Database in Microsoft Excel format.
Through outreach to the utility providers, the consultant will produce a utility contact list: Including utility provider, contact name,
email address, mailing address & phone numbers. These are to be shown in the utility general notes and specifications.
Drawing showing the location of the utilities within the project area. The drawing will depict found and known utilities within the
investigation area at the achieved ASCE 38-02 Quality Level and an 11” x 17” PDF plan set will be signed and stamped by a licensed
Professional Engineer.
CADD file shall attempt to include the following, when it’s possible to do so:
The utility plans sheets will include the utility line work with proper designation colors.
Include manhole rim labels and inverts in and out labels that match the Client’s project datum elevations.
CONTINGENCY TASKS
To achieve the Client’s project goals, the following tasks can be included as contingency tasks for an additional fee if requested:
Perform Test Holes (Potholes) per the QLA Standard outlined in SB-167 & ASCE 38.
At the client’s request, T2 UES, Inc. will complete test holes (potholes) if requested.
T2 UES, Inc. will use the least intrusive excavation method at critical points to determine the precise horizontal and vertical position
of underground utilities, as well as the type, size, condition, material and other characteristics. The client will determine the critical
points based on their design and supply T2 UES, Inc. with a map designating the test hole locations.
The test hole information will be documented on the T2 UES, Inc. Testhole Data Report as shown below and then surveyed. The
client will receive the report and a CAD file with the surveyed test hole locations.
Perform Advanced Geophysics Investigation
Multi-Channel GPR is a relatively new technology to the Utility Engineering industry. T2 UES, Inc. uses the Stream EM and Stream
C which are MCGPR solutions dedicated to utility locating and mapping. These units employ 40 separate channels with double
polarized antennas enabling the system to simultaneously gather data both longitudinal and transversal. The high number of
antennas increases the quality of the data and allows us to detect utilities even in sub-optimal soil conditions.
The Stream EM and Stream C are both equipped with a GPS unit that enables the data set to easily be georeferenced to the
project survey datum.
The system is generally towed behind a vehicle at speeds up to 12 MPH which permits us gather the GPR data using minimal
traffic control thereby reducing the impact to local traffic.
Tasking
Review with the Client where test holes may be necessary to calibrate advanced geophysics tools.
Perform a MCGPR sweep of the site using the STREAM EM and/or STREAM C where applicable.
Prepare deliverables showing the results of each of the above technologies.

RE: Proposal for Geotechnical Engineering Services
Mail Creek Ditch Siphon Pedestrian Bridge
City of Fort Collins, Larimer County, Colorado
Dear Craig:
This letter outlines our proposed scope of services and cost estimate to provide geotechnical engineering services for a
pedestrian bridge (overpass) in Fort Collins, Colorado. We understand that the intent of the project is to create a grade
separated crossing over the Union Pacific Railroad (UPRR) tracks for multi-use trail connectivity in the area between
Harmony Road and Trilby Road. We understand that the proposed overpass is expected to connect the Power Trail
(which runs parallel to the UPRR tracks on the west side) to a future multi-use trail near the Mail Creek Ditch Siphon.
The geotechnical engineering scope of services will be to provide subsurface information, laboratory test results, and
foundation recommendations for the new pedestrian bridge design. Pavement design is beyond the scope of this project.
Site Geology
Published geologic mapping (Geologic map of the Boulder-Fort Collins-Greeley Area, Front Range Urban Corridor,
Colorado, 1978) indicates that surficial soils near the proposed pedestrian bridge location consists of eolium (reddish-
brown deposits of windblown clay, silt, and sand) overlying Slocum Alluvium (brown to white sands and gravels with some
cobbles and boulders closer to the Front Range). The thickness of the eolium ranges from 5 feet to 15 feet thick, and the
Slocum Alluvium can be up to 20 feet thick. The upper shale member of the Pierre Shale Formation underlies the surficial
soils. The bedrock typically consists of gray, silty shale with occasional sandstone and bentonite beds. Near the project
area, the depth to bedrock is estimated to be between approximately 30 feet and 40 feet. Published hydrogeology
mapping (Hydrologic Investigations Atlas HA-746B, Plate 3) indicates groundwater to be approximately 10 feet to 15 feet
below existing grades. Groundwater levels are expected to fluctuate depending on precipitation events and seasonal
weather variations.
Proposed Scope of Services
The proposed geotechnical scope of work is summarized as follows.

• A total of 3 geotechnical borings are proposed and will be drilled to a maximum depth of 100 feet or 20 feet into
bedrock (whichever is shallower) to determine the subsurface conditions including soil type, depth to bedrock,
and depth to groundwater. We understand that the type of bridge foundation has not yet been determined.
Geotechnical penetration samples and composite bulk samples will be collected from the borings. The borings
will be drilled under a single mobilization.
• We anticipate the field work will be completed within 3 business days. We understand that traffic control will not
be required during our field activities.
• Right of Way (ROW) access permits will be obtained through the City of Fort Collins. Borings located on the
east side of the UPRR tracks are expected to be drilled outside the UPRR ROW. Borings located on the west
side of the UPRR may need to be located in the area with a trail agreement between the City of Fort Collins,
UPRR, and the Platte River Power Authority (PRPA). We are assuming that flaggers for the railroad will not be
needed because the borings are assumed to be outside of the 25-foot flagging zone with the railroad tracks. It is
assumed that all coordination with PRPA and UPRR for access will be performed by the City and no fees are
budgeted for this purpose. In addition, no other access requirements for the UPRR are included in this proposal.
• We will assist the drilling contractor with Utility Notification Center of Colorado (UNCC) utility locates prior to
drilling. We have assumed that some utility site meets and boring location adjustments may be required prior to
drilling based on available information regarding the potential occurrence of active utility lines adjacent to the
railroad tracks. We are assuming that the PRPA power line does not restrict access for drilling equipment or
require specialized drilling equipment.
• The exploratory borings will be drilled using 4¼-inch inside diameter hollow-stem augers. A Geocal field
engineer or geologist will log the borings, record groundwater levels and the results of penetration tests, and
obtain representative soil and bedrock samples.
• Soils (and bedrock if encountered) will be sampled with modified California and split spoon samplers using
procedures similar to ASTM D 1586. Disturbed bulk samples will be collected from the borings within about the
upper 5 feet.
• The borings will be backfilled using make-up sands and auger cuttings and compacted with the weight of the drill
rig.
• Soil and bedrock samples collected during drilling will be returned to our laboratory, and selected samples will
be programmed for testing. Typical lab tests will include liquid and plastic limits, swell-compression
characteristics, gradation, unconfined compressive strength, pH, chloride content, laboratory resistivity, and
water-soluble sulfate content.
• The results of the field and laboratory programs will be evaluated to provide geotechnical design criteria for the
proposed pedestrian bridge structure. Our engineering report will be prepared to summarize at least the
following:
o introduction and proposed construction conditions,
o brief review of field and laboratory procedures,

o subsurface conditions encountered (soils, bedrock, and groundwater),
o results of the field exploration and laboratory testing, and
o bridge foundation design recommendations in accordance with the latest edition of the AASHTO LRFD
Bridge Design Specifications.
Proposed Fee and Schedule
We will initiate field work within 10 working days of notice-to-proceed, depending on weather conditions and access. After
the permit is approved and received from the City, the borings will be staked, and utilities cleared.
Our proposed fee to conduct the field work, laboratory testing, engineering analyses, and report preparation is estimated
at $26,201.00 as itemized on the attached Table 1. This amount will not be exceeded without prior approval. A draft
report will be available for review within about 8 weeks of notice to proceed. However, we will keep you informed of our
progress and any information available.
We appreciate the opportunity to assist with this project. If you have any questions or need additional information,
please feel free to give me a call (303) 337-0338.

NOTES/ASSUMPTIONS: Some of the proposed boring locations may need to be accessed via private property. We are assuming that the
client would help coordinate with private property access and mobilization issues. We are assuming that there is no time restriction for drilling
because we are not drilling in an active ROW.

Drill 3 exploratory borings (bridge structure). The structure borings will be drilled to a maximum depth of 100 feet or 20 feet into bedrock
(whichever is shallower). Geocal project management, field engineering, drill supervision and lab analysis will be from Centennial, drilling and
traffic control sub-contractors will be from Denver. Three business days are anticipated to complete the field work. We assume that permitting
will be needed from the City of Fort Collins, but no fees assessed.
