Dear Mr. Sauleda:
In a000rdance with your request, EDM Engineering Solutions is pleased to provide this fee proposal •
for subsurface utility locating services between Morrie Engineering, lac.(CONSULTAN`1), and EDM
Engineering Solutions Inc. (SUBCONSULTANT).
• I. PURPOSE OHS AGREE$ + .TV Mar.Mar= DEpcnirtioN
CONSULTANT is requesting SUBCONSULTANT provide services to locate existing underground
utility iitcilities in the area of proposed' mast ann locations at Biscayne Soulevar4 and 90 to 1 I ss
Streets. The scope of work is limited to the public rights -of -way. The services on 'this project will
include vacuum excavation test holes to confirm the utility, record vertical measurements and mark
the horizontal Location. Survey services are not included Plans showing the proposedi improvements,
the existing facilities and the requested test hole locations were not proiided. To date
CONSULTANT has identified 20 potential test hold locations. ft is anticipated the utilities to be located
will include water mates, gas males buried electric and buried communications. Individual utility
services, storm drainage pipe gravity sewer systems and other utilities are not included.
. 11, SCOPE OF SERVICES
RECORDS RESEARCH -- NOT INCLUDED
HORIZONTAL DESIGNATIONS NOT INCLUDED
VACUUM EXCAVATION TEST HOLES — SUBCONSULTANT SHALL:
1. Obtain from CONSULTANT a current set of plans depicting the existing, utilities and the
proposed test hole locations, and all utility asbuilts, record drawings, utility. atlas maps and
any other information provided by the Utility Owners that depict those existing facilities.
2. Coordinate fieldwork with CONSULTANT.

3. Notify the Sunshine One -Call Network in accordance with State law.
4. Provide approved traffic cones at the test hole location for maintenance of traffic.
3. At the proposed test hole location a) scan the area to confirm the horizontfai location of the
buried facility, b) neatly cut and remove any sod, asphalt or concrete at the meat hole location,
c) use vacuum activation techniques to safely expose the facility, d) measure and record the
depth to the top of the agility, and for a single pipe, the approximate pipe diameter, fbr
multiple duct fhcclllttes record the width, depth and approximate contt+guratibn (Atha facility,
e) backflll the test holes with native soil, compact in lifts and f) provide a restoration of the
surface disturbed by the vacuum excavation. Compaction will be performed with a hand held
tamper, density tests will not be taken. Read the Technical Lbnitalions secdcrrf drat fellaws far
more information corrarning the process. capabilities and limitations of these services.
6. Install an above ground marker at the test hole location. Mark with aptly-1al fat on the ground,
or provide survey lath to identlfy.the test hole number and description. Survey services are
not included.
7. Prepare and provide a report of the test hole results and findings.
TECHNICAL LIMITATIONS; Services will be provided with due diligence and in a manioc coaaistcot with
standards of the subsurfhce utility locating Monty. Every reasonable effort will be made to locale tad utility systems
esf interest whether. indicated on record -plans availebh to us or not. However, no guartmtee cnnn be made that all
existing utility systems can be detected, located or exposed. It may not be possible 10 detect utlllties without prior
knowledge, such as systems that are not depicted on record prints available to us. The horizontalaoastioa effort wilt
include electromagnetic Induction, power source detection, and around penetrating rater. Elecumnagnetic induction
is It method in which a transmitted signal is applied to a metallic target. As long as the twat Is metallic and
unbroken, the argot can be traced and a teceiver at the surface is used to detect the transmitted signal. If** signal
venom be applied directly to the target, induction may be produced Brom the mace. In this scene° bleed -off of the
milit tted signal to an adjacent facility b possible, sometimes resulting in erroneous iafonnabon. PVC, HDPE,
concrete pipe and other non-metallic fhhellities cannot be located by electromagnetic methods. Pouter soxmce detection

(electric, telephone, CAN for example). Ground peaetrating radar (OPR) is available to usi0 is locating non-.
metallic utilities and other tteilities that tyre unidentifiable using traditional electromagnetic tedtnitues. The accuracy
of these techniques Is subject to the limitation of the available technology and certain actors abd meld conditions
beyond our control, such as the size, depth and conductivity of the target, site conditions end amiss, soil conditions,
depth o water able and the existence of adjacent burled materials and debris. The targeting of nitbeitribee utilities,
although highly reliable, is expressly understood to represent an approximate location of the ferny marked on the
ground surface. Facilities located from the surface are usually found within one foot of the surtceamark. Once a
possible facility has been located from the audio, vacuum excavation services should be toed to , ly verify and
to provide the accurate horizontal location and vortical measurements (a test hole). Vacuum excavation to dmiques
are used to provide a cost-effbettve service tltst causes minimal disturbance to the site, the utility, yehlcle traffic, and
is acceptable to the permitting agencies. The size of the test hole excavation is kept to a minimum; in most cases the
nominal size of a test hole is 11" x tl". Visual verification in the test hole below the water able is not possible. An air
lance probe can be used in these instances to a reasonable depth of approximately 6 feet, although results to greater
depths may be possible. The bottom of the utility pipe and conduit 11 sometimes not directly available and In most
cues can be derived from the crown of the pipe and the pipe diameter. Pipes with a diameter less than 16" can
usually be determined by exposing a potion or the entire pipe as needed. If pipe diameter is critical on pipe lhcllitics
greater than 16", additional test holes may be required to obtain both edges. The bottom depth or multple conduit
and encased duct barks is determined by excavating down ono edge of the utility. Additional test ha'Ies are needed to
accurately document both edges, configuration and top and bottom depths. Condltiom under multiple or encased
