GENERAL DESCRIPTION 1.1 The Consultant shall perform Routine, Initial and Emergency inspection including reporting and minor remedial actions of Traffic Signal Mast Arms (TSMA) & High Mast Light Poles (HMLP) on State Highway System in Miami- Dade County. 1.2 This is a structural inspection of the traffic signal mast arms and high mast light, they will not include items related to functioning of the traffic signal. Mast Arm is a Structure that cantilevers over traffic with a single mast arm. The primary components are the foundation, the base plate, anchor rods, pole to base plate connection, pole, mast arm to pole connection and mast arm. High Mast is a structure supporting light. The primary components are the foundation, base plate, anchor rods, pole to base plate connection, pole and luminaries. High mast poles also have a luminary raising devise and generally a slip joint (or more) in the post. The foundation, electrical ground, anchor rods, base plate, pole, moment connection, splice plates, shall receive hands on inspection. The mast arm horizontal member (arm) and the high light, pole top and the luminaries may be inspected using binoculars, with on hand on inspection if problem areas are detected. 1.3 The consultant will develop all the inspection report using the Department s Bridge Management System BrM 1.4 All Mast Arms in each intersection have one structural alpha numeric DOT number (6 characters plus one consecutive digit) the Attachment A shows how to do it. Also, each intersection has the corresponding Dade County ID #. Each High Mast Light Poles have one structural alpha numeric DOT number (6 characters). If the structural number is not clear legible; it will be repainted. The photo of each structural number should be added to report. The TSMA Dade Page 2 of 15

3 County ID # is going to be printed in the Inspection Report, not painted in the field. 1.5 The TSMA and HMLP inspection frequency is 60 months (5 years). The Department intends to spread evenly the total amount of inspections in 60 months (5 years). The Department has the option to have a Mast Arm Structure inspected more frequently based on the condition of the Mast Arm or High Mast Light Pole. 1.6 The consultant will perform (1) one full inspection cycle. 2. PERSONNEL REQUIREMENTS 2.1 An inspection team will consist of a Team Leader and an Assistant. Due to the extent of welded members found in most ancillary structures, it desirable for at least one team member to have experience in visual weld inspection as well as training in locating and recognizing fatigue cracking. The Team Leader should be confirmed officially by the Department as a Certified Bridge Inspector. Qualifications for Certification as a Bridge Inspector as stated in the Rules of the Florida Department of Transportation, Chapter A qualified inspector must be in the field to supervise inspection activities at all times. To be qualified, an individual should be CBI or must be registered as a Professional Engineer in Florida and experienced in the inspection of Bridge Structures according to the National Bridge Inspection Standard. 2.2 Each final Traffic Signal Mast Arm and High Mast Light Pole inspection report shall be signed by the field bridge inspector and signed and sealed in accordance with the Florida Statue b y the Professional Engineer, which confirms the accuracy and completeness of all the report contents. 2.3 An organizational chart shall be submitted to the Department for approval prior to starting work. The organization chart shall include the number and names of key personnel, team size, and which individuals are assigned to the various work tasks. Any changes from the original organization chart must be submitted to the Department's Project Manager for approval. The notification must be in writing within seven (7) calendar days of the change. 2.4 Each final inspection report shall be sealed in accordance with Florida Statute by the Professional Engineer, which confirms the accuracy and completeness of all the report contents. 2.5 Due to the nature and scope of the require services, it may be desire for the consultant to subcontract portions of the work (i.e. scanning). The consultant shall be authorized to subcontract these services under the provision of this document. 2.6 Subcontracting firms and the work they will perform shall be identified in the original proposal. The subcontracting firm must be approved in writing and Page 3 of 15

Any changes in the subcontracting firms or the work they will perform as indicated in the consultant s proposal shall be subject to review and approval by the Department. 3.1 Field inspection must be conducted in accordance with the publications listed in this scope. 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 conditions which must include the personal inspection of all significant deficiencies. This individual is also responsible for assuring the accuracy and completeness of all data records compiled as a result of the Consultant s field activity. This individual as also responsible for insuring that mast arm numbers are in place and legible on each Traffic Signal Mast Arm and High Mast Light Pole. 3.2 Every visible surface of all members of each Traffic Signal Mast Arm and High Mast Light Pole structure 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 the one that would require more than two (2) hours for the inspection team to perform. The Department Project Manager should be consulted prior to any major cleaning operation. 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. 3.3 Where deficiency dimensions are documented, the actual width, length and location on the member should be recorded. In cases where dimensioning every deficiency is impractical, the standards Department Table of Deficiency Dimension Classes, must be used in lieu of undefined general term, such as narrow, fine, etc. 3.4 If by field observation, deficiencies are sufficiently critical to warrant immediate and substantial traffic restrictions, or present an imminent hazard to the public; the Department Project Manager or designated representative must be immediately verbally notified. Verbal notification must be confirmed with written notification within 24 hours. 3.5 As a safety precaution the Department recommends that all inspection personnel utilize a personal non-contact AC voltage detector to check for the presence of errant current in TSMAs during inspections. 3.6 Traffic control procedures must be in accordance with the FHWA/USDOT Manual on Uniform Traffic Control Devices, the Department s Roadway and Traffic Design Standards. All LCR must be requested 14 working days prior to the closure date. Page 4 of 15

5 3.7 As part of the inspection procedures all loose anchor bolt jam nuts, lock nuts and leveling nuts (when accessible) will be tightened in accordance with Department standards, documented in the inspection report 3.8 A hands-on inspection of the entire length of the vertical (surface area and welds) is required. A hands-on inspection of the upper connection(s) will include all welds, plates, and fasteners and that portion of the horizontal arm(s) that can be reached without extending over traffic lanes. The inspection of the remainder of the horizontal (arm/arms) will be performed on the entire perimeter of the horizontal arm with vision enhancing equipment (binoculars) of sufficient quality, resolution and magnification to detect small deficiencies in the mast arm sections. Special attention will be given to the slip joint (if present) for any indication of stress, cracking, galvanizing overlay or deterioration (missing fasteners, corrosion staining, movement, etc.). Deficient paint systems will also be reported. If significant deficiencies of any kind other than missing slip joint fasteners are suspected or detected, a hands-on inspection will be required. 3.9 MAINTENANCE ITEMS TO BE HANDLED DURING INSPECTIONS The Certified Bridge Inspector will be responsible to perform the following maintenance activities as part of the inspection Painting of Structural Components with Cold Galvanizing: The inspectors will clean and paint only primary structural elements if any corrosion is found on the structure. Electrical components will not be painted. The painting will be limited to a maximum of 2 square feet per sign or 4 separate areas (totaling less than 2 square feet per sign). Cold Galvanizing will be supplied by FDOT Missing or loose Anchor Bolt Nuts: Any loose or missing anchor nuts and/or jam nut discovered during inspection shall be provided and tightened using torque wrench fulfilling the FDOT standards. No work order will be issued for tightened nuts. Anchor bolt nuts will be supplied by FDOT U-Bolts: Any loose U-bolts discovered during inspection shall be tightened using torque wrench fulfilling the FDOT standards Miscellaneous Bolts (Excluding Anchor Bolts): Any loose, broken or missing bolts discovered by the inspection shall be replaced and/or tightened using torque wrench fulfilling the FDOT standards. When potential failure condition exist that could endanger the traffic bellow, the structure should be considered as critical. In the situation, the Department Project Manager must be notified immediately so that appropriate action can be taken Loose High Strength Bolts: Loose high strength bolts (at the moment connectors, box section connectors, and primary element connections) will be tightened to the extent possible by the inspector, but will not be tightened to a specified torque value. This information will be documented in the Page 5 of 15

6 element inspection notes in the report. See District Six Policies on page 13 of the scope Missing High Strength Bolts and Nuts: The inspectors will not replace missing high strength bolts and nuts, but the inspector will obtain the required size of the missing fasteners to be documented in the element inspection notes in the report. See District Six Policies on page 9 of the scope Missing and Loose Sign Panel and Sign Backing Connection Bolts: The inspector will tighten loose sign panel and sign backing bolts. Inspector will replace all missing sign fasteners if accessible and not an excessive effort. Fasteners will be supplied by FDOT. 4. INSPECTION REPORT 4.1 BrM Inspection Report The consultant will develop all inspection reports utilizing the latest version of BrM. The report will contain all documentation specified by this agreement and must meet the requirements of the Manual for Bridge and Other Structures Inspection and Reporting Procedures. Any addendum to the report shall be converted to a pdf file and stored in BrM. The Consultant must develop, publish and submit a report for each structure. The report must be sign and sealed by the registered Professional Engineer. The Bridge Management System database will be updated with the new inspection date within 30 days after the inspection is completed. The inspection report will be completed within 60 days of the completion of the field inspection. Inspection Date: (90) Should be opened in BrM the same calendar month that is due previous inspection. Database will be updated in 30 days... day 30 Final Revision, Sign & Seal in 5 days... day 35 Department approval or return error 10 days... day 45 Resubmitted fixed in 15 days... day Within sixty (60) days after completion of each inspection, the consultant shall furnish the Department with the original of each inspection report. All inspection reports must be uploaded to EDMS Each inspection report shall be a stand-alone document. Letter size paper shall not be used for reports. Page 6 of 15

7 4.1.3 Deficiencies described in previous inspection reports must be addressed again in the current report. Terminology not commonly understood by noninspection personnel should be minimized and undefined values or rating shall not be used. An inspection report must provide a comprehensive description of all deficiencies and state probable causes of the deficiencies, specific required correction action and contain an evaluation of any previous corrective action. Any deficiency that cannot be described in BrM should be addressed in an addendum and will be attached to the report Reports must have a close numbering system, with the total number of pages in the report shown on each page, for example, Page 10 of Comprehensive Report of Deficiencies Deficiencies shall be reported in the same numerical order as they appear in the inspection report and shall be indexed by the element number. Under each element subheading all deficiencies and their causes shall be reported referencing ant attached sketches and photograph by number This section shall contain a brief but comprehensive description of the deficiencies. The probable cause of deficiencies should also be identified. Identifying the probable cause of the deficiencies serves two purposes; first, the most effective repair can only be determined if the source of the deficiency has been identified; second, when the same cause for a specific deficiency is documented repeatedly, a body of evidence becomes available to justify its elimination through a change in design Deficiencies shall be described in enough detail to allow rates of change to be monitor over consecutive inspections. This requires liberal use of size and location dimensions, sketches and photographs. A sketch illustrates only the essential features of a deficiency without distracting detail and whenever it is more effective, a sketch shall be used in lieu of a photograph Photograph shall be used only when a sketch is not practical or to illustrate one typical example of a severe and/or common type of deficiencies, photographs illustrating a typical example must be taken. When photograph is taken, an object that provides a sense of scale such as a ruler should always be included in the photograph. The date the photograph was taken and the mast arm number shall always be marked on the front. Photograph shall be taken in color. Color frequently adds significantly to the effective description of a deficiency. When photographs are included in the report, each copy of the report submitted to the Department shall include a color print of each photograph. All photographs should be part of the inspection report. Page 7 of 15

8 5.2.5 The consultant shall research documentation for recording mast arms identification data, the date erected, date manufactured erector and manufacturer. 4.3 Evaluation of Previous Corrective Action The purpose of this section is to evaluate the effectiveness of repairs that were performed since the previous inspection. Repairs recommended in previous inspection but not completed shall be addressed in the Recommended Corrective Action Section. Each repair should be inspected carefully to determine if the repair effectively corrected the deficiency. The written evaluation of each repair should be presented in this section. 4.4 Recommended Corrective Action This section shall contain all deficiencies requiring maintenance, repairs, or rehabilitation with recommended corrective action for each deficiency without addressing methods, quantities, or cost of such action. All deficiencies identified shall be included in this section if only to note that no corrective action is required Deficiencies serious enough to cause a current or imminent traffic safety hazard must be flagged in the left margin with the word CRITICAL in capital letters adjacent to the element number. The following items are considered critical deficiencies: Cracks or fatigue related deficiencies in fracture critical structural members Deficiencies that require immediate attention and are deemed critical must be signed by the register Professional Engineer When reporting missing, loose or corroded nuts and bolts always provide the deficient quantity, size and the total quantity (Example: 2-inch leveling nut on anchor bolt #3 is loose). 4.5 Photograph Inventory Certain mast arm features can best be determined by examining a photograph. The photographic views shall be provided by the consultant for each mast arm to insure adequate reference: the entire mast arm elevation on both faces (on several photographs, if required) including foundations, anchor bolts, typical splice moment connection, structure number, columns and arms. All photographs should be labeled with the structure number, view, and feature, date taken and attached to Mast Arm Report. A general profile intersection photo in the direction Page 8 of 15

9 of the inventory should be incorporated in the inspection report. The photographer should avoid the backlighting 4.6 Location Map The consultant will provide each inspection report with the structure location maps for the purpose to illustrate the physical location of each structure. 4.7 Electronic Document Management System (EDMS) The consultant shall provide personnel proficient in the use of computers and scanner operation to input related inspection documents into an Electronic Document Management System (EDMS) within fifteen (15) calendar days of the final report submittal. This will require familiarity with the Structures Management Documents guidelines for EDMS posted on the FDOT Infonet and the District 6 EDMS Naming Conventions and Attribution document. Duties will include scanning and attributing documents in the Department's Electronic Document Management System. Documents imported into the EDMS will be in PDF format. Documents such as inspection reports and photo inventories that are created in BrM will be downloaded from BrM. This effort should be included into the cost of scheduled inspections and payment will not occur until this is completed to the Department PM's satisfaction. 5. QUALITY CONTROL The consultant shall institute quality assurance procedures, which shall be provided in writing to the Department for review and approval before work begins. Quality assurance procedures are an integral part of this contract and are not a separate pay item. The Department may perform additional quality assurance by inspecting mast arms that have been previously inspected by the consultant and reviewing the inspection records for conformity with the Department s finding. 5.1 Quality Reviews The consultant shall conduct quality reviews to make certain his own organization is in compliance with the requirements cited in the scope of services. Quality reviews shall evaluate the adequacy of materials, documentation, processes, procedures, training, guidance, and staffing included in the execution of this contract The Quality Assurance Program should also have a second, peer review level. The peer review can be conducted internally by the consultant s organization or by subcontracting the review to another consulting firm Page 9 of 15
