RE: FDEP Contract Number CN 229, Change Order 1 for Task Assignment Number 21 Trail Connect – Toms Harbor Channel to Toms Harbor Cut and Toms Harbor Cut to Long Key Unforeseen Additional Services – Subsurface Utility Exploration

Dear Mr. Sandel, WGI, Inc. (WGI) is pleased to provide this additional services proposal to the Florida Department of Environmental Protection (FDEP, CLIENT) for subsurface utility exploration services due to unforeseen conditions on the above referenced project. Tasks being requested by the Department are outlined in the attached Scope of Work, along with corresponding fees. In addition, it is agreed that WGI’s services will be performed pursuant to the contract terms and conditions included in Agreement Number CN229, executed on May 11th, 2016, Amendment Number 1 dated February 4, 2021.

The project consists of the design of proposed trail improvements to the Florida Keys Overseas Heritage Trail in Monroe County, Florida. New portions of the trail will be constructed from Toms Harbor Channel to Toms Harbor Cut (an approximate length of 0.65 miles) and from Toms Harbor Cut to Long Key (an approximate length of 1.2 miles). The missing sections of the trail have mangroves along the shoulder and a shoulder that slopes towards the water.

The scope of services included in this proposal are the installation of an asphalt walkway to connect the existing trails from Long Key to Toms Harbor Channel for a total trail length of 1.85-miles. Our understanding is that the new trail will consist of a 10-foot-wide asphalt paved path with the potential use of retaining walls to support the trail.

Please let me know if you have any questions regarding the attached information.

Sincerely, WGI, Inc.

Subtask and A: Utility Designating (ASCE 38-22 Quality Level B) and Utility Test holes (ASCE 38-22 Quality Level A) Description: WGI will perform Subsurface Utility Engineering (SUE) of the areas depicted in figure 1 below. A detailed scope of the SUE services is provided below:

Utility Designating (ASCE 38-22 Quality Level B) w/ Survey & CADD

WGI will perform an ASCE 38-22 Quality Level B (QLB) utility investigation (designates) on existing utilities for verification and horizontal alignment confirmation for QLA Investigation within project limits as shown in Exhibit A.

This QLB investigation includes direct induction of toneable subsurface utility facilities from surface accessible features, and Ground Penetrating Radar sweep for non-toneable facilities. Detected facilities will be marked with American Public Works Association (APWA) compliant colors; flags and water based paint on soft ground and washable chalk on hard surfaces.

WGI will perform survey and location of utility designates using network corrected GNSS surveying methods tied to project control – includes offsite NGS control point verification.

Utility Test holes (ASCE 38-22 Quality Level A) w/ Survey

WGI will provide an ASCE 38-22 Quality Level A (QLA) field investigation (vacuum excavation test holes) within the project limits at the proposed locations as directed by EOR, as needed for utility verification, horizontal / vertical confirmation and in support of civil design services and conflict analysis.

WGI will perform survey and location of utility test holes using network corrected GNSS surveying methods tied to project control.

Any additional QLB and/or QLA days exceeding the proposed amount can be added with written CLIENT authorization, while WGI crews are on-site during initial mobilization.

This proposal is based on two (2) test holes requested.

BASIS OF SCOPE

1. WGI proposes to provide an ASCE 38-22 QLB utility investigation (designates) in order to determine the horizontal alignment of the existing utilities within the project limits (Exhibit A).

2. Geophysical designating techniques, although highly reliable, are subject to outside interference, which are beyond the control of WGI, and may impede the effectiveness of subsurface utility investigations. Soil conditions, utility materials, size, depth, salt water and conductivity may prevent the location of some subsurface utilities. WGI utilizes state of the art equipment and methodology during all phases of utility investigations, but no guarantee is hereby expressed that all facilities will be detected.

3. Survey services are included.

4. Horizontal control will be referenced to NAD83/2011 Adjustment and vertical control referenced to NAVD88.

5. Drafting and/or other CADD services are included.

6. CLIENT shall facilitate access for WGI field staff.

7. CLIENT shall provide a list of known utilities and any drawings, as-builts or other source of information that may help in the location of said utilities.

Trail Connect Toms Harbor Channel to Toms Harbor Cut and Toms Harbor Cut to Long Key

8. Basic work zone safety includes safety road signs and traffic cones.

9. Traffic control, lane closures, if needed are included.

10. Per Diems / Hotels per 2024 GSA rates.

EXCLUSIONS

1. ASCE 38-22 Quality Level A Investigation (test holes) is limited to two (2) test holes.

2. Traffic control conduit investigation is not included.

3. Permits and permit fees, if needed, are not included and are the responsibility of the

CLIENT.

4. Mapping of irrigation lines and sprinkler heads is not included.

5. Invert elevations of storm drainage manholes, culverts, catch basins, and outfalls including pipe sizes and types are not included in the SUE scope.

6. Sanitary sewer (gravity), service laterals and secondary services (private) are excluded.

7. Off duty police not included.

DELIVERABLES

1. WGI will provide a CADD deliverable with the QLB investigations drafted in plan view.

WGI will provide a Utility Report of Subsurface Utility Investigation in PDF format.

LIMITS OF WORK

FIG 1: Toms Harbour Channel

Performance Measure: Deliverables will be reviewed by the Department to confirm they are complete, accurate, and timely.
