*This project is currently on a stop work notice with 5 days remaining.
1. Per the original scope of work,Cardno Inc.performed a thorough Bridge inspection Report(SIR)for Structure No.030184.
Findings in the Consultant's BIR indicated that the depth measured from the left bridge rail at Pier 13 during the 2017 Bridge
Inspection may have exceeded the scour critical depth by 1.3 feet.The concern was that the original revetment system,which
was installed to protect the pier against scour,may have been moved by Hurricane Irma. •
On Change Order No.1,the Consultant was asked to prepare an assessment detailing the findings of the inspection and the
condition of this scour countermeasure system for a not-to-exceed fee of$18,049.16 and 72 calendar days.Per the rationale of
Change Order No.1,Change Order No.2 would be processed once the results of the proposed assesment were known.
Per the attached Exhibit A-Scope of Services for Change Order No.2,the Consultant will design scour countermeasures,as
well as provide permitting services required for said scour measures,for a not-to-exceed amount of$67,973,32 and an
additional 365 days.
2. The scope described above was not included In the original contract as the potential conditions descxbed above were not
known prior to the SIR performed by the Consultant.
3. Scour is one of the main causes of bridge failure,and not processing this change order could leave the aforementioned
potential issues untreated

Change Order No. 2
Bridge Number: 030184
1 PURPOSE
The principle intent of this Change Order is to provide design a permitting for Stan
Gober Memorial Bridge (No. 030184) Scour Countermeasures.
2 PROJECT DESCRIPTION
After data from the FDOT Bridge Inspection Report (BIR) was reviewed in concert
with the Phase IV Scour Analysis and 2008 Scour Countermeasure Plans, it was
determined that the depth measured from the left bridge rail at Pier 13 during the
2017 Bridge Inspection exceeded the scour critical depth by 1.3 feet. Due to concerns
with the scour countermeasure system including potential shifting due to Hurricane
Irma, the CONSULTANT provided further investigation and evaluation of the Scour
Countermeasures at Piers 6, 7, 8, 9, 12, 13, 14, 15, 16.
Based on recommendations from the investigation and evaluation, this scope
includes the design of scour countermeasures as well as the additional permitting
services required for the scour countermeasures into the CONSULTANT's "Stan
Gober Memorial Bridge Repair Assessment Report".

INTERA PROPOSAL
Local Scour Countermeasure Design for the Stan Cober(Goodland) Bridge(CR-92 over Marco
Channel)(Bridge No.030184)
Collier County
INTERA Incorporated
January 2019
Problem Understanding
Collier County has requested the design of local scour countermeasures for the existing Stan Clober
(Goodland) Bridge over Marco Channel (Bridge No. 030184). Cardno, Inc. requested preparation of this
Scope of Services from 1N1'ERA Incorporated. The purpose of this Scope of Services is to provide
recommendations regarding the existing scour protection and to develop to design scour countermeasures
for several of the interior bents.
Assumptions
We based our scope of services on the following assumptions:
I. Cardno will provide INTERA with survey data (bathymetric and topographic) from the bridge
location.
2. Cardno will provide INTERA with plans of the existing bridge.
3. Design will rely upon existing hydraulic modeling of the area contained in the Phase 2 Scour
Evaluation Report for the bridge.
Scope of Services
Task I Data Collection
INTERA will collect information and data necessary to perform the study including bathymetric data,
topographic maps, bridge inspection reports, scour evaluation reports, and bridge plans. Also during this
task, INTERA will compile the design hydraulic conditions at the site from the existing modeling. This
task will not include a site visit.
Task 2 Recommendations Regarding Existing Protection
As part of the rehabilitation project,Cardno indicated that an underwater inspection will occur to evaluate
the condition of the existing scour protection. Based on the results of this inspection, INTERA will
develop recommendations regarding rehabilitation,augmentation,or removal of the existing protection.
Task 3 Scour Countermeasure Design
INTERA will develop the conceptual design for the scour protection. This includes defining the
horizontal and vertical extents, specifying the type of material (e.g. sizing rubble riprap), and
incorporating any design constraints. INTERA will document all methods, procedures, and results in a
letter report. Additionally, as part of this task, INTERA will review the construction plans and
specifications developed by Cardno to ensure that the final drawings reflect the conceptual design as well
as to address any variances as they arise.
Task 4 Quality Control Review
INTERA will conduct a complete internal review before submission to the Cardno for its review and
comment.
Task 5 Project Coordination/Meetings
1N'I'IRA will participate in teleconferences, as necessary, with the Cardno during the length of
INTERA's involvement with the project.
Budget
The cost to perform these services is$14,257.32.This cost reflects 91 hours of fully burdened labor.
