Re: "Bayshore- Package A" revised
Mr. Da Silva,
Ground Hound Detection Services, Inc. (GHD) is pleased to provide the following proposal for utility locating services
at the above referenced project. As outlined in your e-mail on February 23, 2007, GHD will provide vertical
information and verification of all indicated utilities at the targeted areas as depicted on the supplied drawings.
GHD will provide the following:
Using EM &GPR techniques, GHD will provide/verify horizontal locations of targets to be excavated.
Vacuum excavation to expose, verify and record all pertinent information with regards to the utility.
Provide test hole data sheets depicting our discoveries.
DESCRIPTION OF SERVICES:
Electromagnetic induction is a method in which a transmitted signal is applied by directly coupling to a desired target.
As long as the target is metallic, a receiver is used to detect the transmitted signal. Passive power detection is another
technique used to locate naturally occurring magnetic fields present on power cables generating a 50/60Hz signal.
Additionally, passive VLF signal can be detected on other metallic utilities that are typically long in length and are well
grounded electrically. Some utility systems contain portions ofnon-metallic material and therefore may be un-locatable
using the EM method.
A GPR unit can assist in identifying nonmetallic utilities and other structures that are unidentifiable using the traditional
EM techniques. The GPR method transmits electromagnetic waves, which are pulsed at discrete/time intervals. The
transmitted pulse radiates through the earth whereby a portion of the energy is reflected from interfaces of contrasting
electrical properties (e.g. pavement and soil interface, soil stratigraphic changes and buried metallic objects) while the
remaining energy continues until reaching additional reflectors where the process is repeated. Reflected energy is
received by the antennae and recorded for later processing and interpretation. Factors such as soil moisture, clay
content and variations in the dielectric constants of materials control the effectiveness of the GPR method. Wet
conductive soils severely attenuate GPR signals and thus affect the depth of exploration. GPR energy cannot transmit
through ferrous objects since metal acts as a pure reflector. In order to accurately conduct a radar survey, orthogonal
scans must be made across the target area. Confined or obstructed areas that restrict the scanning pattern can impede
the data collected and reduce the accuracy of the desired results.

Mr. Cedonio Da Silva
February 23, 2007
Vacuum excavation is anon-destructive technique used to safely expose utilities using a combination of compressed
and vacuum air. Once the utility has been exposed, vertical elevation, diameter and material type can be obtained.
Conditions such as groundwater, hard, rocky soils, sub-surface obstructions and targets at deep elevations can limit the
effectiveness of vacuum excavation. Targets beyond the limitations of the Vacuum system may be "probed" with an air
lance. This technique is effective in determining elevation but may be ineffective for determining outside diameter and
material type. Duct banks, large diameter targets and structures often require multiple excavations in order to acquire
desired information.
Incorporated herein: Locating underground utilities is not an exact science. Therefore, Ground Hound Detection Services, Inc.
("GHD") expresses no guarantees that using one or any of the available technologies for identifying utilities/structures will identify
all utilities/structures and/or meet the objective of each individual project. CH2M Hill understands that limitations within the
available technology, the complexity of site conditions and circumstances beyond the control of the GHD may limit the
performance/results of GHD's services. The services provided by GHD shall be performed in accordance with generally accepted
professional practices as related to the nature of services performed. GHD cannot guarantee that all utilities within any given survey
area will be identified as a result of inherent limitations within the technology and existing site conditions. CH2M Hill and any of
its subcontractors shall hold harmless and indemnify GHD against any and all losses as a result of inability to locate or mislocate
due to limitations within the available technology, the complexity of site conditions and circumstances beyond its control, but not
against negligence on the part of GHD or its employees. Hand digging is required in all situations when excavating within 24" of
GHD's markings.
This proposal constitutes the entire agreement between the parties. The agreement may not be altered, modified or
conditioned in any respect without the prior written consent of all parties. Documents such as but not limited to "change
orders", "purchase orders", sub-contract agreements, and statements of terms and conditions of work shall require prior
written acceptance by GHD to be binding. Payment to GHD for work performed pursuant to this proposal shall not be
contingent upon GHD's consent to any proposed alteration, modification or condition to the agreement.
CONDITIONS -Locating of underground utilities for pre-excavation/design purposes:
• Utility locations are being provided in an attempt to prevent or reduce the likelihood of damage during excavation
and/or provide design information.
• Areas to be surveyed must be level and free of obstructions.
• GHD's inability to complete the project due to conditions outside of GHD's control does not void this contract.
• If GHD is to produce a map (optional), customer is responsible for providing an electronic AutoCAD file for GHD
to map its discoveries. If a file is not available, additional costs and time to produce the drawing are likely.
• Maps produced by GHD are not considered to be "survey grade" drawings. GHD will include dimensions from a
fixed feature in the field to the horizontal position of the target being depicted. Drawings are not prepared by a
licensed Engineer, Surveyor or Draftsman. Drawings are not prepared to any State survey or drafting standard.
• If GHD reviews its discoveries with others responsible for data collection, a copy of the file must be forwarded to
this office for review.
• APWA standards are used for marking utilities.
• GHD is not responsible for moved, altered, and obliterated marks or maintaining marks. GHD will impose an
additional fee to relocate/remark facilities.
• If underground facilities are damaged, whether marked by GHD or not, it is your responsibility to notify a
representative of GHD within 48 hours of the damage.
• GHD is not a substitute for Chapter 556 of the FL State Statute (Underground Facility Damage Prevention and
Safety Act). Prior to project construction, excavating contractor is responsible for securing locations of public
utilities through Sunshine State One Call of Florida (800-432-4770).
• Any available as-builts, engineered or other record drawings with regards to any utilities within the project
limits must be made available to GHD for its review prior to commencement of field services. The
performance of GHD's services is limited to full and unobstructed access to include but not limited to:
mechanical rooms, manholes, hand holes, vaults, meter rooms, telecom rooms, fixtures (plumbing, electrical,
communication), dispensers, fenced compounds, tanks and structures. Full cooperation from the on site
personnel is necessary to perform a complete survey.

RE: Revision 3-Additional Design Services forRight-af-Way Infrastructure
Improvements Program -Neighborhood No 8 Bayshore and Sunset
Islands: Traffic Study at the intersection of Prairie Ave. & West 28~
Street
Dear Mr. Mistry:
As requested at the Bayshore Progress Meeting on December 19, 200( and per the revisions
to the scope discussed at the February 1, 2007 Progress Meeting (outlined below) and the
March 2, 200' Conference call, we are pleased to re-submit the attached fee proposal for
additional Design Services for a Traffic Study at the intersection of Prairie Ave. & West 28~
Street. The fee requested to perform this work is $20,780 (Not to exceed) with Traffic Signal
Warrants as an Additive Alternative at $ 8,443 (Nat to exceed}, as detailed in the attached
Surnmary Sheet.
Please refer to Attachment A for detailed Scope of W ork to be pxovided.
CHZM HILL staff is available to begin work immediately on this study. Upon completion of
the traffic counts, Iexpect afour--week period to perform the analysis and prepare a report
stating the findings and recommendations. Therefore, I expect that CH2M HILL can submit
a Draft Report for your review within six (5) weeks of receiving written notice to proceed
{NTi').
If you have any questions, concerns or require additional information, please do not hesitate
to contact me at your convenience.
Sincerely,
Polar Doran, P.E.

Attachment'A'
Realignment West 28th Street and Prairie Avenue
Scope of Work
Project Understanding
A need has arisen to look at alternative aligrunents for the intersection of West 2Sth Street
and Prairie Avenue. This would consist of a conceptual redesign of the intersection and
evaluating how it would impact traffic operations.
There will be one alternative conceptual redesign of the intersection.
The background traffic will be calculated using an annual growth rate of 5%. The
background traffic will include trips generated by any other anticipated developments at
the time the study is performed.
Only this intersection will be analyzed.
The following tasks specifically detail the analysis to be conducted under this scope of work.
Task 1: Conceptual Design
Re-configure the intersection into one alternative traffic configurations:
1. Two separate Prairie Avenue Intersections along West 28th Street
Task 2: Data Caliection
Count data will be collected for the intersection of Prairie Avenue and West 28th Street to
determine the existing AM and PM peak hour volumes.
The background data will only include areas of impact that are on record or acknowledged
by the city planning staff.
Any additional count data required is in addition to this scope and will require additional
agreements.
Task 3: identi#y and Review Area of Impact
An area of impacf will be developed and agreed upon by the City. Once this area has been
determined then background data can be gathered.
Task 4: Traffic Volume Development
CH2M HILL will produce trip generation estimates of the background conditions based on
the bt" Edition of the ITE Trip Generation Mr;nicnt. Other sources such as previous studies or

field observations maybe utilized if the~manual does not contain sufficient data for a
particular land-use. Traffic volumes will be developed for the following scenarios.
{2007} Existing Condition Volumes for the AM and PM peak hours and the AM and PM peak
hour volumes for the alternative {4 ea.}
{200?) Existing Condition Volumes + Background Volumes for the AM and PM peak hours and
the AM and PM peak hour volumes for the alternative (4 ea.)
(2017} Existing Condition Volumes + Background Volumes for the AM and PM peak hours and
the AM and PM peak hour volumes for the alternative (4 ea.}
Trips will be allocated to the local road network using a distribution based on existing
turning movement counts, knowledge of local conditions and traffic patterns or existing
planning models. Percentages may require revision i# new traffic counts and/or feedback
from City staff indicate that study area traffic circulation patterns have substantially
changed. We are intending to use the existing knowledge to determine the distribution. Any
additional analysis required to do this is outside of this scope and will require additional
agreements.
Task 5: Intersection Analysis
CH2M HILL will analyze traffic operations at the intersection identified under Task 1 using
the current Highway Capacity Software to determine intersection level of service (LOS}.
Qther more extensive analysis techniques may be used (Synchro, Simtraffic) depending
upon the nature of the intersection and its surroundings. We will analyze AM and I'M peak
hours (based on .available data} under the following scenarios:
(2007} Existing Condition Volumes for the AM and PM peak hours and the AM and PM peak
hour volumes for the alternative (4 ea.}
(2007) Existing Condition Volumes + Background Volumes far the AM and PM peak hours and
the AM and PM peak hour volumes for the alternative {4 ea,}
(2017) Existing Condition Volumes + Background Volumes for the AM and PM peak hours and
the AM and PM peak hour volumes for the alternative (4 ea,)
CH2M HILL will evaluate if the intersections meet traffic signal warrants per the 2000
Manual on Uniform Tra#fic Control Devices (MUTCD}.
Intersections that are shaven to operate below LQS standards will require further mitigation
analysis. Typical intersection mitigation measures include installation of a traffic signal,
addition of exclusive turn lanes, or movement restrictions such as prohibiting left turns.
Any 2017 mitigation will be analyzed on a planning basis, using "Rule of thumb" mitigation
beyond any previously identified mitigation needs. Additional mitigation beyond this level
would constitute additional work to this scope.

Task 6: Report
CH2M HILL will prepare five (5) copies of a draft report summarizing the findings of this
evaluation for distribution to the appropriate City staff. Upon receipt of comments from
City staff, CH2M HILL will prepare up to 10 final copies for the City. CH2M HILL
anticipates two meetings with City staff to discuss results during the course of the project.
Task 7: Quality ControV Quality Assurance
The analysis will be subject to internal review by qualified CH2M HILL staff.
Alternate 1: Traffic Signal Warrants
CH2M HILL will analyze traffic operations at the intersection identified under Task 1 to
identify if the intersection warrants a traffic signal under the alternative. This would
include the additional data needed to faalitate this effort.
1) Additional Data Collection:
• 24 hour approach counts summarized hourly
• 8 hour intersection TMC
• 12 month crash history
We will collect the appropriate volume data required fa perform the warrant analysis. We
assume the crash history data is available from the authorities. If data is not available, the
appropriate methods for determining warrant analysis will be used with no impacts to fee
or schedule.
2) Warrant Study:
• Stop sign delay study
• (2007) Existing Condition Signal Warrant
• (2007) Existing Condition + Background Signal Warrant
• {2017} Existing Condition + Background Signal Warrant
