PREFACE The “Field Inspection Guide” is a condensed version of the “Ontario Structure Inspection Manual (OSIM). It summarizes the major parts of the main manual including inspection procedures, material defects, condition states, maintenance needs and perform-ance deficiencies. References to the main manual are also made in this Field Guide so that the inspector can obtain more comprehensive information, if required.

1. STRUCTURAL INSPECTIONS 1.1 INSPECTION OBJECTIVES (Part 1, Sect. 1.2) The goal of the structural inspection is to ensure, within an economic framework, an acceptable standard for structures in terms of public safety, comfort and convenience. The main objectives are to:
• maintain structures in a safe condition • prolong the life of structures • identify maintenance & repair needs • provide the basis for structure
management 1.2 INSPECTION ACCURACY (Part 1, Sect. 1.3) In order to achieve the inspection objectives and adequate accuracy, the inspector should spend at least 2 hours at a typical bridge site to adequately assess the condition of all elements. The inspection should be a visual inspection per-formed “Close enough to determine the element condition”, and generally conducted “within arms length” of the element. In some cases it may be possible to inspect a por-tion of the bridge close-up and then estimating the condition of the remaining inaccessible parts by visually comparing them to the partial close-up in-spection. If this is done, periodic Enhanced OSIM inspections must be done to closely inspect all components as described in Part 1, Section 1.3.2 of the OSIM. Additional equipment should be used to facilitate inspection, when necessary (Bridgemaster, bucket truck, ladder, etc).
STRUCT

Additional specialized testing (NDT, etc) should be recommended for critical structures (fatigue prone, fracture critical, hangers, etc) 1.3 ADDITIONAL INVESTIGATIONS (Part 1– Clause 1.3.4) If during a detailed visual inspection, the inspector feels that more detailed information is needed, specialized inspections (within a certain timeframe*)can be requested. Some of these investigations are:
• Detailed Deck Condition Survey • Non-destructive Delamination Survey
of Asphalt Covered Decks • Substructure Condition Survey • Detailed Coating Condition Survey • Underwater investigation • Fatigue investigation • Seismic investigation • Structure evaluation • Monitoring, etc.
* Normal timeframe is within 2 years 1.4 SITE INSPECTION (Part 2-Clause 1.5.2) The inspector shall: • Arrange for special equipment/traffic
control and safety devices, as required for site.
• Complete an overview inspection of the site
to: ⇒ Assess the overall integrity of the
structure and identify areas where more detailed examination may be required
⇒ Observe the bridge under truck loading and identify any abnormal flexibility, deflections or noises (rattling or vibration

⇒ of members) ⇒ Look for abnormal deflections, settlements or
rotations by looking along the rail or barrier wall or other members
⇒ Identify obstacles that may either interfere with the inspection or indicate a need for additional special equipment.
• Determine the quantities in each condition state
based on the severity of material defects in the appropriate units (m2, each, etc.), for each element. Details of condition states and material defects are included in Appendix “A” and “C”. The element list is included in Appendix “B” and the OSIM form for recording information is included in Appendix “E”.
• Determine the performance deficiencies,
maintenance needs, recommended work and time frame for work for each element. Details of these are included in the Appendix “D” of this Guide
• Take photographs to adequately describe the
structure and the defects found including all areas of POOR.
• Update element quantities/dimensions if
required. • Correct missing/erroneous inventory data
STRUCT
8
1.5 POST INSPECTION PROCEDURES (Part 2 - Clause 1.5.3) The inspector shall: • Ensure that all inspection equipment and
temporary traffic control devices are removed from the site and the site is left in workmanlike order
• Ensure the appropriate follow-up action is taken (notify bridge owner immediately) for any critical structural defects or deficiencies (i.e. fatigue cracks in steel, imminent deck punch through, etc.) and all other unsafe conditions that are discovered in the field.
• Submit the Maintenance Needs list to the maintenance crew for action
• Ensure additional investigations are initiated in the timeframe recommended
• Write all necessary follow-up correspondence and reports

2. HELPFUL HINTS (Part 2, Section 4)
1. CONDITION • First look for areas of POOR
• Concrete ⇒ Spalls, delaminations, severe
scaling, wide cracks (4m=1 sq.m defect area)
• Steel ⇒ More than 10% section loss,
cracks and deformations • Actual inspection quantity (e.g. sq.m.)
should be used for elements in Poor condition—not percent.
• Next, look for areas of FAIR
• Concrete ⇒ Medium defects (medium scaling,
medium cracks, etc.) • Steel
⇒ 1% to 10% section loss • Each Area of Poor (except for very
large areas) should generally have an equal area of associated Fair sur-rounding it.
• Remainder of areas probably in Good or Excellent Condition. • Actual Good or Excellent depends
on visual inspection; however, age of structure can be used as a guide, depending on environmental expo-sure of element (see section 2.2 of this guide).
• Similar guidance based on age does not exist for the transition from Good to Fair Condition. ⇒ Fair is determined by visual iden-
tification of defects.

2. EXCELLENT AND GOOD
• All materials must begin in the Excellent condition state
• Once any defect is visible, it drops to the Good condition state
• The defects may not be visible from a distance, but are from close-up.
• Guidance is provided below for the age of compo-nent when transition* from Excellent to Good is expected:
• Concrete, ACR Steel, Coated Steel, Coating: • Severe—5 years • Moderate—15 years • Benign—25 years
* Transition can be spread over a few inspections.
• Defects in Good condition state include (see Tables in Appendix C for complete list):
• ACR Steel
• First signs of patina flaking
• Coated Steel • First signs of surface rust • First signs of coating lifting from
steel • Re-coated steel that had rust previ-
ously • Coating
• First signs of adhesion or coating related defects
• Concrete
• Hairline and Narrow cracks • Surface carbonization • Light scaling • Other light defects

3. RECOMMENDED WORK (Part 2, Sect. 7)
Work on Element Recommended work
- Must be consistent with condition of element. - Must be used for elements that cause a bridge to
be placed on a capital construction program, typi-cally the 5 main elements listed below.
- Can be used for other elements as required. - Must not be used for work that is carried out as
maintenance. - Must not be used for additional investigations or
functional deficiencies. Recommended work on an element can be either:
- “Rehabilitation” - “Replacement”
The timeframe for the work is either:
- “1 to 5 years”, - ”6 to 10 years”
Typically, the 5 main elements require repair in 1 to 5 years when: Deck Top 10% to 20% Poor Deck Soffit 5% to 15% Poor Barrier Wall 15% to 30% Poor Expansion Joint 15% to 25% Poor Girders 5% to 10% Poor
o Sometimes, a lower percentage of Poor may also trigger a rehab for critical ele-ments.
o If there are immediate safety concerns with some elements, a Structural Mainte-nance item should be recorded.
HINTS
14
Work on Structure Work on structure is only required when there is enough to warrant placing the bridge on the capital construction program. Recommended work on the structure can be either:
- “Minor Rehabilitation” that include work on ele-ments other than the deck (i.e. barriers, bear-ings, etc.)
- “Major Rehabilitation” that include work to the deck (i.e. patch-waterproof-pave, overlay, etc.) plus possibly other elements.
- “Replacement” of entire structure. The timeframe for the work is either:
- “1 to 5 years”, - ”6 to 10 years”

4. PERFORMANCE DEFICIENCIES (Part 2, Section 6)
A Performance Deficiency should be recorded if an element’s ability to perform its intended function is in question.
• “Suspected” Performance Deficiencies are re-corded for each element
• Potential Deficiencies categorized as “Suspected” since often difficult to ascertain the significance of defect at the time of the inspec-tion
• “Suspected” Performance Deficiencies usually indicate some follow-up action is required (strength evaluation, specialized inspection, monitoring, etc.)
• Standard List of possible deficiencies are shown on the inspection form (see Appendix D and Appendix E).
• Follow-up action can be addressed under “Additional Investigations” or “Special Notes” for the bridge.
Example: A severely corroded girder at the midspan
• Can the girder safely carry traffic loading? • Inspector cannot determine this in the field • Inspector can only indicate “Suspected” Per-
formance Deficiency for a follow-up strength evaluation
• Only then can decision be made whether bridge needs strengthening or posting
HINTS

5. MAINTENANCE (Part 2, Section 6) There are two types of maintenance work that are performed: Structural Maintenance Work - Is work to improve the structural capacity of a
specific element and not part of a larger con-struction contract
- Is generally only done to one element - Include emergency repairs and holding strat-
egy repairs - Is work that requires engineering drawings to
complete the work. Routine Maintenance Work - Is for preventative maintenance and minor re-
pair work that can be performed without engi-neering direction.
- Is usually carried out by bridge crews or road maintenance contractors
For all Maintenance work a standard list of mainte-nance needs are shown on the inspection form (see Appendix D, or Appendix E). The mainte-nance needs list should be forwarded to mainte-nance crews for action, with urgent items flagged for immediate attention.

ASPHALT (Part 1, Sect. 2.7)
• Distinction made between rating the as-phalt wearing surface and the deck top be-neath the asphalt
• Asphalt defects are put into two major cate-
gories: • Top-Down Defects (defect originates in
asphalt and includes:) • Bond Defects (loss of bond and
rippling) • Surface Defects (ravelling, slippery
surface and flushing) • Surface Distortions (wheel track
rutting) • Isolated Cracks (Light and medium
isolated cracks)
• Bottom-Up Defects (defect probably originated in concrete deck and reflected in asphalt surface) • Pattern cracking (map, alligator,
radial, edge cracking) • Wide isolated cracks (transverse,
longitudinal) • Local Underlying Defects (local
potholes and protrusions)

DEFECTS

COATING
• Used to protect the underlying steel • Not as much an immediate concern, but a
durability concern • Three main categories of defects:
1. Coating related defect—related to the composition of the coating
2. Adhesion related defect—related to
the bond between the steel and coat-ing
3. Application related defect—poor ap-
pearance due to improper application

APPENDIX C: MATERIAL CONDITION STATE TABLES (Part 2, Section 4) Four Condition States have been defined for bridge elements, namely, Excellent, Good, Fair and Poor. The condition of bridge elements is defined to be in any one or more of these Condition States. The “severity and extent” philosophy is used where, for each bridge element, the inspector assesses and records the amount (area, length or unit as appropri-ate) of the element in each of the four Condition States.

Notes: 1 – For “All”, place the entire component (100%) in one condition state. 2 – For “Each”, give the number of occurrences of the component in each state. 3 – For cracks in concrete, estimate repair area (4m of crack = 1 sq. m of repair). 4 – For cracks in steel, estimate required repair area. 5 – Tables given are typical for element. Use appropriate table for applicable material. (See Section 4). 6 – Sub-elements (End/Middle) to be used for the following elements at expansion joint locations: Deck Top, Girders, Inside Boxes Sub-elements (End/Intermediate) to be used for the following elements at
expansion joint locations:: Floor Beams, Stringers, Bracing and Dia-phragms
Sub-elements (End/Interior/Exterior) to be used for Soffits Sub-elements (Interior/Exterior) to be used for Barrier/Parapet Walls 7 – For an explanation of which bridge components are included in each element, see Table 3.1. 8 – Similar element types should be grouped together (e.g. I-girders, x-frames, etc.) 9 – Optional element. Not required for MTO use 10 – For these elements that are inspected by linear metre, a defect in the post shall be assumed to affect the tributary area for that post.
