Re: Village of Key Biscayne: Underground Electric Distribution Facility Conversions -
Utility Data Gathering
Dear Mr. Abbott:
The Corradino Group, Inc. (CORRADINO) is pleased to submit this proposal to provide
Underground Electric Distribution Facility Conversions Data Gathering Services on the above -
referenced project. This proposal encompasses the effort defined below and includes the following
sections: Background, Scope of Work, Compensation, and Understandings.
BACKGROUND
The Village of Key Biscayne (Village) is embarking on an aggressive Utility Hardening Program
consisting of improvements within an area of the Village that serves 1,143 single- and multi-
family homes, plus government,
commercial, office, institutional, and
recreational facilities. The Program is to
include installation of subsurface Florida
Power & Light (FPL) electrical lines, as well
as other below -ground utilities such as
Comcast and AT&T lines (i.e., cable and
telephone) within the same trench.
SCOPE OF WORK
During a December 13, 2016, meeting with
Village personnel (Mr. Jud Kurlancheek, Ms.
Ana de Varona, Mr. Jose Lopez, Mr. Tony
Brown, and Ms. Mariana Dominguez -
Hardie) and its Consultant (Mr. Paul Abbott — HPF Associates), CORRADINO was requested to
provide a draft proposal for review to the attention of Mr. Abbott; This proposal covers:

■ Mobile Mapping Data Gathering of existing utility features to include:
✓ Manholes, valves, pump stations, fire hydrants, utility risers, sanitary drain and
storm water structures, utility poles, light poles, and edge of pavement.
• Preparing residential property electrical service location schematics by:
✓ Conducting an in -the field visit to all single-family and multi -family residences
within the proposed undergrounding area limits to visually identify the side of the
property in which the electrical service is located.
• Conducting above-ground/below-ground existing utility gathering analysis along the
rights -of -way within the undergrounding area limits:
✓ Above -ground utilities - Electric and communication lines.
✓ Below -ground utilities - water distribution, storm and sanitary sewers, electric and
communication lines, traffic and pedestrian signalization and control systems,
pumping and supply locations.
SCOPE OF WORK
The tasks to be conducted are:
Task 1 — Mobile Mapping Data Collection
This phase of the data gathering will be accomplished by collecting new mobile LiDAR imagery
of the existing project conditions and extracting point features from the collected point cloud and
imagery. The data captured will include visible utility features along and up to 100 -feet outside to
the right-of-way, limited only by line -of -sight obstructions. The features listed below in the
Feature Extraction section of the proposal, beginning on page 3, will be extracted in vector format
from the mobile LiDAR data and conform to CAD standards specified by the client.
■ Mobile Data Acquisition - CORRADINO will deploy the Optech M1 Mobile Mapping
System (MMS) to the project location and drive all lanes of the corridor to collect above-
ground features visible from the sensor position. CORRADINO will set 2 GPS base stations
within 5 km (16,400 feet) of the project site, one as a primary base and one as a secondary
fail-safe, to support the MMS acquisition. Following setting and confirming the control, data
acquisition will begin. LiDAR-collected data/imagery will be viewed using real-time
acquisition software to ensure the entire data collection area has been covered and to identify
and remedy data voids, if any.
MMS data collection will be conducted to ensure data redundancy. Each roadway will be
driven in both directions to complete feature capture. The data will be collected so that there
is a minimum side -overlap of 20% between adjacent scan passes. A minimum of 15 minutes
will be maintained between the end of one pass and the beginning of the next overlapping
pass to ensure that sufficient satellite constellation changes have occurred between passes,
reducing the opportunity for bias in the GPS measurements.
• Mobile LiDAR Processing - CORRADINO will use the local Virtual Reference Station (VRS)
network and/or established base stations to support the acquisition process. Acquired data will
be processed utilizing the onboard Positioning Orientation System (POS) data, local VRS
Page 2
network and GPS base stations set by CORRADINO. This method is sufficient for subsurface
utility location consistent with this scope. However, should increased accuracy levels be
desired at a later date, CORRADINO will use additional targeted ground control points in the
trajectory solution, which will be collected at an additional cost to be determined at the time
of data collection, based upon client specifications.
CORRADINO will use a simultaneous adjustment (least squares) of the raw navigation
trajectory with weighted (constrained) project control points to establish the best trajectory and
exterior orientation parameters for the LiDAR sensor (and any other sensors such as a camera).
• Feature Extraction - The first step in feature extraction will be converting the data into a point
cloud in LASer format. Because of the volume of data collected, CORRADINO will partition
(a.k.a. "tile") the project by a 250' x 250', or similar, grid. This will allow users to access,
view, and manipulate the deliverables without overwhelming existing computer processors.
CORRADINO will extract the required planimetric data from the processed point cloud data
along the MicroStation CAD environment. Imagery and LiDAR data per "tile" will be loaded
into TopoDOT software to classify individual LiDAR clusters through special algorithms.
Once the initial classification has been completed, desired features will be classified
individually. Within the graphical user interface (GUI), a form will be completed which will
include all attributes of the feature being identified. These `Element Tags' will be exported as
shape files to include attributes added during the feature -identification process. The location
of each feature, as close to the center of the feature as possible, will be validated. All data will
be compiled using three dimensional (3D) digital data collection procedures and will conform
to the standards defined by the client. Data will include GPS coordinates, digital images, and
metadata for each collected feature. Feature identification and attribution processes will
continue for all assigned areas, until each acquisition block is complete.
The shape files will be imported to a Master Feature Geodatabase. Upon its completion
CORRADINO will perform a final QAIQC of the data by applying custom scripts that will
flag errors, including missing attributions, misspellings, missing images, etc. The county right-
of-way (ROW) and centerline data will be utilized for reference and included in the deliverable.
• The following public ROW data will be extracted from the MMS:
• Manholes (identified with a point feature, with description)
• Valves (identified with a point feature, with description)
• Pump stations (identified as a point feature, with description)
• Fire hydrants (identified as a point feature, with description)
• Utility risers (identified as a point feature, with description)
• Storm structures (to include curb inlet locations, grates and other above ground
visible evidence
• Utility poles (identified with a point feature, with description)
• Light poles (identified with a point feature and a picture of the light fixture with
description)

Trite 01" 41-1 rA-�vi i�•iv vR%UP
• Includes the "most -representative" photograph of the light fixture as identified in
the imagery collected during the mobile mapping collection
• Edge of pavement (identified with a line feature, with description)
Data may be collected any time after notice to proceed as vertical "control" information will
consist of manhole rim elevations recently collected by MDWASD. Horizontal positioning of the
dataset will be accomplished through the use of real-time kinematic GPS observations in
conjunction with the Mobile Mapping vehicle's on -board GPS and IMU (Inertial Measurement
Unit) positioning system. A GPS base station may be established to collect static observations to
support post -processing of vehicle trajectories, as needed to support project accuracy expectations.
Final data processing will commence upon receipt of vertical control information.
The principal product of Task 1 will be electronic files of extracted data.
Task 2 — Existing Utility Records Data Gathering
An analysis of existing above -ground and below -ground utilities will be performed within the area
bounded for the future electrical distribution undergrounding. Utility records will be researched
to identify utility owners that may have facilities on or be impacted by the project utilizing the
one -call notification center (Sunshine 811), visual inspections and available utility owner records
(GIS databases, prior construction plans in the area, direct -buried cable records, distribution maps,
transmission maps, service record cards, "As-builts" and Record Drawings, field notes).
Electronic and paper communications will be sent to the contacts listed for each utility, with in -
person follow-up to facilitate transfer of the available "as-builts", GIS databases and/or shapefiles.
The following summarizes the utility stakeholders to be involved in this effort:
• America Traffic Solutions - traffic control ("red-light" cameras) at the following
intersections: Crandon Boulevard at Harbor Drive, Crandon Boulevard at Key Colony, and
Crandon Boulevard at Galen Drive.
• AmeriGas DBA Siegel Gas -a propane gas service provider typically not found within
public rights -of -way with limited impacts to the proposed underground conversions.
• AT&T Florida - communications services provider to private, public and institutional
customers with much of the existing facilities being aerial (majority of the residential
service provided from rear lot lines).
• Comcast Cable - communications services provider to private, public and institutional
customers with much of the existing facilities being aerial (majority of the residential
services provided from rear lot lines).
• Miami -Dade County Public Works and Traffic - traffic control facilities that include buried
and above -ground cable connecting to traffic signals.
• Florida Power and Light (Distribution) - primary and secondary power services provider
to private, public and institutional customers with much of the existing facilities being
above -ground, with the majority of the residential properties connected from the rear of the
lot.
• Florida Power and Light (Transmission) — high -voltage power provider to the substation at
the north end of the Village of Key Biscayne (not impacted by the proposed underground
conversions).

• Hotwire Communications - communication services provider to The Sands within the
Village of Key Biscayne with subsurface facilities within public rights -of -way.
• Miami -Dade Water and Sewer - water and sewer service provider to private, public and
institutional customers with facilities placed within public right-of-way providing essential
services requiring the protection of its existing below -ground facilities for uninterrupted
service.
• Village of Key Biscayne — the Village plans, installs and maintains the storm water
infrastructure placed within the public right-of-way providing storm water management
along all Village -owned right-of-way. This infrastructure requires consideration and
protection during proposed undergrounding.
• Atlantic Broadband — communication services provider in the Village, but to be determined
if service provided in the project area.
All communication with utility owners will be tracked and logged in a Utility Communication
Tracking Log to identify the timeframes for requests for information and responses from utility
owners. All data gathered during this effort will be cataloged and delivered electronically.
The principal product of Task 2 will be the Utility Communication Tracking Log, cataloged
electronic vector data and electronic pdf construction as-built/record plans.
Task 3 — Existing Residential Property Electrical Service Schematics
In -field visits to 1,143 properties will be made in an attempt to determine the electric meter location
and the telephones service connection, focusing on the side of the structure each service is
connected to. This information will be used in the subsequent design by FPL to determine the
location for electrical handholes for individual services.
To determine the approximate location of the service, each property will be observed from the
street and, where necessary, by using existing aerial photography, and location trends of
surrounding properties. The following information will be documented for each property:
• Property address;
• Folio number;
• North arrow;
• Sketch depicting the side of the property where the electric and telephone services are
located.
The principal product of Task 3 will be an electronic pdf of containing the sketches noted above.
