10 FIN NOS: & WORK ITEMS 4.1 Field Inspection Field inspections must be conducted in accordance with the publications listed in Section II. The Professional Engineer or Certified Bridge Inspector on site shall be responsible for the detection of all deficiencies and the determination and recording of the structure's condition which must include the personal inspection of all significant deficiencies. This individual is responsible for assuring the accuracy and completeness of all data and records compiled as a result of the Consultant's field activity. This individual is also responsible for ensuring that bridge and bent numbers are in place and legible on each bridge. The consultant shall have the responsibility of supplying materials necessary for labeling bridges appropriately to the satisfaction of the Department s Project Manager Every visible surface of all members of each bridge must be examined. Members that cannot be examined because of debris, vegetation, etc. should be cleaned if the effort involved is not excessive. Excessive effort is that which would require more than two hours for the inspection team to perform. The Department Project Manager should be consulted prior to any major cleaning operation. Bridge members and elements that cannot be inspected prior to report publication must be documented in the report as such, along with the reason for not inspecting Where deficiency dimensions are documented, the actual width, length and location on the member should be recorded in feet and inches noting any increase/decrease numerically since the last inspection. In cases where dimensioning every deficiency is impractical, the standard Department Table of Deficiency Dimension Classes, must be used in lieu of undefined general terms, such as narrow, fine, etc The Consultant shall not allow any lead bridge inspector to perform consecutive routine inspections on the same bridge. If this occurs, the Consultant shall re-inspect the bridge using another inspector at no charge to the Department If by field observation, deficiencies are sufficiently critical to warrant immediate and substantial traffic restriction or closing of the bridge, the Department Project Manager or designated representative must be immediately verbally notified. The District 3 policies have been attached to this scope. See Attachment B for the District 3 Bridge Posting Local Government-Owned Bridges Memo. See Attachment C for the District 3 Bridge Closure-Local Government Bridges Memo. See Attachment D for the District 3 Scour Critical Letter-Local Government Bridges Memo.

The Department Project Manager or representative will accompany the Consultant when meeting with the bridge owner. These meetings may be held prior to beginning actual field inspections and/or may be held subsequent to inspections in order to present bridge reports to the owner The meetings should include a brief discussion of bridge inspection program regulations and objectives, an outline of the bridge owner s specific responsibilities, particularly the bridge owner s responsibility to close and/or post bridges with recommended weight restrictions and to correct deficiencies that endanger the traveling public. The discussion of the bridge inspection program should cover as a minimum the Department Rules, Chapter 14-48, F.A.C., and Bridge Inspection Standards. The discussion should include the importance of notifying the Department when structures that are structurally or critically deficient are either repaired or replaced and when recommended weight restriction postings have been accomplished The general format and content of a typical bridge report, bridge location map, the report for monitoring follow-up action on critical bridge deficiencies, summary of various posting/deficiency/scour letters and a summary of the condition of each structurally deficient bridge shall be explained by the Consultant in order to familiarize bridge owners with the records they are to receive. After the bridge inspection reports are presented to the owner, the Consultant must be available to answer a reasonable number of questions by telephone. 4.7 Bridge Location/DetourMaps The Department must maintain, for every public bridge in Florida, a Location/Detour Map. The Consultant shall create a Location/Detour Map for every bridge during a routine inspection or verify that an existing Location/Detour map exists and is applicable. If the existing Location/Detour map is not accurate or no longer applicable, an updated map must be created. The consultant can choose whichever software deemed appropriate to create the Location/Detour map if the Department Project Manager approves of the format. The detour which is established shall utilize comparable roadways with comparable bridge load ratings to the bridge which is being detoured. The Consultant shall scan the Bridge Location/Detour Map into EDMS file upon completion as a standalone document A-13 STAGE III (07/31/2017)

14 FIN NOS: & Electronic Bridge File The Consultant shall perform a review of the official electronic bridge file to ensure all required documentation is stored and attributed. If there is data missing the Consultant is required to update and bring the official electronic bridge file into compliance. 4.9 Bridge Scour Evaluations Provisions for Work The Department recognizes the necessity of maintaining qualified expertise in the dynamic field of Bridge Scour Evaluation. A multi-disciplined Team of Engineers is required to ensure proper evaluation. Experts in Bridge Hydraulics/Hydrology, Structures, Geotechnical, Coastal Engineering and underwater inspection are required to come to a consensus on potential bridge scour associated problems and possible corrective actions. The key individuals within the team having direct oversight of this work must demonstrate by formal education and or experience the ability to meet the qualifications described below. An individual may qualify in more than one discipline. Should any key individual terminate their employment relationship with the contracted firm, the Department must review and approve the replacement before continuation of any work requiring that expertise. Failure to maintain the required expertise makes the contract null and void at the option of the Department. It will be required that engineering analyses, calculations, etc. be signed and sealed by the appropriate overseeing Professional Engineer. The Consultant is required to perform a scour evaluation as requested by the Project Manager. The evaluation will be performed in three (4) Phases: (1) Data Collection and Qualitative Analysis (2) Hydrologic and Hydraulic Assessment, (3) Geotechnical and Structural Scour Assessment, and (4) Recommend Plan of Action. The following provisions govern services: 1. A review shall be made at the completion of each phase to coordinate what course of action is needed and what should be included in the next phase. The Consultant shall not proceed with the next phase until authorization has been issued. 2. The Consultant shall review available survey data to determine if there is a need for an additional survey. If required, the Department may authorize the additional survey to be secured by the Consultant. 3. The Consultant shall coordinate and attend technical review meetings with the Department personnel during the course of this study. 4. The Consultant is required to submit to the Department a scour evaluation report for the structure evaluated. This report shall contain all office and field data and all information relevant to the evaluation. This report shall be A-14 STAGE III (07/31/2017)

15 FIN NOS: & Services recorded on 8 ½ x 11 sheets, fully titled, numbered, dated, indexed, and signed and sealed by the engineer of record according to Florida Statutes. Computer output forms and other oversized sheets shall be folded to 8½ x11 size. The data shall be stapled and punched for insertion in the Departments Bridge Inspection Report, and any computer files produced for this report, shall become the property of the Department. At the end of the project, all written data will be submitted on compact disks, in a suitable format for downloading to the EDMS. This scope provides the information to be developed, and the methods and procedures to be followed in performing Scour Evaluations for existing waterway bridges in District 3. This scope document is not all-inclusive; the Consulting Engineer must use good judgment in its application to ensure that the evaluation is complete and appropriate for the site. Ingenuity in applying concepts and procedures is encouraged. However, approval from the Department must be obtained to vary from the general methodology and specific requirements presented in these guidelines. The Federal Highway Administration (FHWA) Technical Advisory is referenced for policy guidelines in scour evaluation. The FHWA HEC-18 is referenced for detailed scour analysis process for riverine situations. The FEWA HEC-20 is also referenced for stream stability analysis. HEC-18 Methodology should not be applied to analyze tidal hydraulics. The intent of this scope document is to describe a phase process for bridge scour evaluation, with each phase being the completion of a logical step in the site evaluation. The findings of each step will provide guidance to the requirements and direction of evaluation for the next phase. A documentation and executive summary report, for each completed phase, will be provided to the Department's interdisciplinary team for approval before proceeding. This report will include plans of action for the next phase. It is possible that a conclusion could be reached at any phase in the process eliminating the need to proceed further. The following is a summary description of the steps to be performed in each phase. Each site has its particular characteristics and levels of risk. The evaluation detail must be commensurate to these site-specific factors. A form titled "Scour Evaluation Report" (provided by the Department) shall be used as summary documentation of the completed findings and recommendations unless a different format in writing is approved by the Department's reviewing engineer. The report is to be appropriately completed for each phase. Stream stability and scour evaluation for this bridge shall be developed using a multidisciplinary approach involving the hydraulics engineer, geotechnical engineer, coastal engineer and the structures engineer. Each phase will involve the expertise of the A-15 STAGE III (07/31/2017)

16 FIN NOS: & appropriate technical specialists. It is the Consultant's responsibility to ensure the appropriate expertise and a coordinated approach is used in each phase. The Consultant based on need and negotiations with the Department may provide additional services. These services may include: 1. Soil survey 2. Hydrographic survey 3. Dive services 4. Pile Testing A. Phase I: DATA COLLECTION AND QUALITATIVE ANALYSIS The site and data analysis for this phase is qualitative and of the simplest form. It involves preliminary conclusions and findings based on the application of simple geomorphic concepts and the engineers evaluation of data and site conditions. There may be some instances where sufficient information is found and conditions are such that a scour assessment and bridge stability recommendation can be made at this level. Note: these steps are similar to those found in FHWA HEC-20. Step 1- Perform an office data search and collection of information pertinent to the structure. When available, this data shall include: Construction Plans Bridge Inspection Reports Hydraulic and hydrologic data Foundation reports, test boring data, site geology, and subsurface information Other Agency Studies such as the Corps of Engineers (COE, Federal Emergency Management Agency (FEMA), Soil Conservation Service (SCS), United States Geological Survey (USGS), Water Management Districts (WMD), etc. Mapping Aerial Photography Gauge data Step 2 Conduct a field investigation (not a formal survey) to supplement existing data found during the office investigation. Collect information such as: Sufficient topographic and elevation data to develop or supplement plan profile drawings of site The current typical channel and flood plain cross-section beyond the area affected by the bridge crossing in accordance with bridge inspection standards Probe where practicable to obtain or confirm structure foundation elevations Observe and record channel and floodplain characteristics as well as up and down stream of the crossing, in accordance with bridge inspection standards Describe the observed geological conditions at the site including their A-16 STAGE III (07/31/2017)

The report shall include: Drawings and photos of the site Summary of important site data Definition of the stream geomorphic characteristics according to the most current/version edition of FHWA HEC-20 Definition of overall stream stability (lateral, vertical, potential responses) Conclusions and recommendations Proposed General Outline of direction and study procedures will be submitted for the next phase B. Phase II: HYDROLOGIC & HYDRAULIC ASSESSMENT FOR SCOUR ANALYSIS This phase involves the basic engineering analysis and development of quantitative information for bridge scour assessment Guidance in specific areas of evaluations and levels of detailing will be provided in the findings of Phase I. It is very probable that the Phase I findings will identify some steps that can be eliminated in Phase II as well as some that need to be expanded. Step 1 Evaluate flood history of the site and develop runoff relations. Non-Tidally Influenced Flow: Hydrologic data for freshwater flow conditions used for the design of cross drains shall be based on one of the following methods as appropriate for the particular site: A frequency analysis of observed (gage) data should be used when available. If insufficient or if no observed data is available, A-17 STAGE III (07/31/2017)

However, the procedures below shall be calibrated to the extent practical with available observed data for the drainage basin or nearby similar drainage basins. - Regional or local regression equation provided in Chapter 5, Volume 2-A of the Department's Drainage Manual for areas greater than 243 hectares (600 acres). - Rational equation for drainage areas up to 243 hectares (600 acres) where real rainfall methods are not readily available. - For regulated or controlled canals, hydrologic data shall be requested from the controlling entity. Prior to use for design, this data shall be verified to the extent practical. Tidal Flow: Coastal Engineering analysis as typified by the US Army Corps of Engineers and consistent with current Coastal Engineering practice should be used in the analysis of Astronomical Tides and Hurricane Storm Surges. Step 2- Hydraulic analysis will be made to determine basic hydraulic conditions at the site, such as velocity and flow distribution. In some cases this information may be available from previous studies or existing design calculations. Tabular summary of the findings of the hydraulic analysis is to be prepared including finding of Step Five. Analysis of scour potential shall follow the same guidelines used in design regarding frequency and conditions in FHWA HEC-18 & HEC-20. RIVERINE CROSSINGS Bridges: The hydraulic performance of bridges over riverine waterways shall be analyzed using the FHWA WSPRO computer program. The detailing of the WSPRO study should be commensurate to the site conditions and performed with an understanding of the sensitivity of the finding when applied in scour predictions methods. A tabular summary of the findings of the hydraulic analysis is to be prepared. Bridge-Culverts: The hydraulic performance of bridge-culverts at riverine waterways shall be analyzed based on the techniques provided in the most recent version/edition FHWA Hydraulic Design Series (HDS) 5. Design charts based on HDS-5 are A-18 STAGE III (07/31/2017)

Tidal Crossings: Coastal Engineering analysis as typified by the practices of the US Army Corps of Engineers and consistent with current Coastal Engineering practice should be used in the analysis of Astronomical Tides and Hurricane Storm Surges. Step 3 Grain size analysis shall be made of the bed and bank materials if appropriate as directed by the Department (collected in Task I) and readily available. Particle size gradation curves will be developed. Information on depths of material and erodability characteristics should be described. Step 4 Evaluation of channel stability should be made through analysis of incipient motion parameters. Potential for development of a naturally occurring armor layer should be assessed using incipient motion analysis FHWA publications HEC-20 and Highways and the River Environment are referenced for detailed procedures in incipient motion and armoring analysis Step 5 Calculate scour depths for the foundation components at the bridge crossing at a minimum for the conditions described below. Where tip elevations of deep foundation elements are unknown, unless directed otherwise by the Department, calculate scour depths assuming the foundation tips extend beyond/below the maximum scour elevation. Worst case scour condition up through the 500-year frequency flood event (Check Scour Flood Event). Scour Components: Scour estimates for the above events shall consist of the total scour resulting from the following: Natural channel aggregation and degradation anticipated during the life of the structure; Channel migration anticipated during the life of the structure; Contraction scour; Local scour, including pier scour and abutment scour. Abutment scour estimates are not required when standard rubble riprap protection is provided and the design velocities near the abutment do not exceed 1.22 meters per second (4 feet per second). Procedures presented in FHWA HEC-18 (latest version/edition) shall be used in developing the scour depths, except that Sheppard s Pier scour equation and scour-resistant material approach should be used, where applicable, rather than the A-19 STAGE III (07/31/2017)

This report shall include: Plot of bridge foundation elements and computed scour depths. Where deep foundation tips are unknown, explicitly denote same on plot Proposal and detailing of additional information required for analytic assessment of structure scour stability (specifically geology and unknown foundation determination) Conclusions and recommendations Proposed general outline of direction and study procedures will be submitted for the next phase B. Phase III: GEOTECHNICAL & STRUCTURAL SCOUR ASESSMENT Step 1 Analyze potential scour depth and extent, including consideration of the foundation material's resistance to scour. Step 2 Analyze capacity of each foundation unit for loads and structural stability under scour conditions defined in Phase II, Step Five. Step 3 Evaluate live load capacities in accordance with the Department's current load rating guidelines. When appropriate, recommend reduced load rating and/or posting limits. Step 4 Prepare and present summary of this phase to the Department. This report shall include: Capacity of each foundation unit as defined in Step Two above Conclusions and recommendations Prepare and submit a general outline of direction and study procedures will be submitted for the next phase C. Phase IV: RECOMMENDED ACTION Develop a Plan of Action (POA) in accordance with HEC-l8 for scour critical bridges and those with unknown foundations. Provide a basic analysis of countermeasure alternatives and their estimated cost for presentation and consideration by the Department. For physical countermeasures, at least one alternative should be presented. For scour critical bridges, the POA should include: Specific instructions regarding the type and frequency of inspections to be made at the bridge, particularly in regard to monitoring the performance and closing the bridge, if necessary, during/after flood events A practical schedule for timely design and construction of scour countermeasures recommended for the protection of the bridge. That is, the time and cost involved should the Department determine this course of action at this point in time A-20 STAGE III (07/31/2017)

21 FIN NOS: & For bridges with unknown foundations, the POA should take into consideration the service life of the bridge, the volume and type of traffic, and the importance of the highway system. The POA should include: Description of foundation and scour condition Development and implementation of a scour monitoring and/or inspection program Development of a plan for closure of the bridge, if needed Approximate determination of cost, if feasible, of nondestructive testing to determine the foundation characteristics Feasible countermeasure(s) to reduce the risk from scour A practical schedule for timely design and construction of scour countermeasures to make the bridge safe from scour and stream instability.
