<br />any of the resource categories. If additional manpower is required and not <br />available, a policy should be developed to establish priorities for the <br />inspection of culverts with openings under twenty feet long. When data is <br />available, prioritization could be according to condition, opening length, <br />rise, or other factors. Specialized equipment and personnel may also be <br />needed on occasion for problems that are beyond the scope of an SI&A <br />inspection. Specialists in hydraulics, soils, materials, or structua1 <br />analysis may be needed to support the inspection program by investigating <br />unusual or potentially hazardous situations. <br /> <br />c. Scheduling Requirements--Inspection schedules are generally prepared at <br />several levels including organizational, supervisory, and working levels. The <br />organizational schedule is prepared to insure that all structures are <br />inspected at the appropriate intervals. The supervisory schedule is prepared <br />to coordinate the use of manpower and equipment. The level of detail is <br />greatest at the working level. The detailed working schedule is very specific <br />in terms of the date, structure to be inspected, and personnel to conduct the <br />inspection. The working schedules for culvert inspections may require that <br />special consideration be given to seasonal stream levels and weather. Brush <br />clearing may be required before culverts can be inspected. Ideally structures <br />should be inspected during periods of lowest flow. However, it is often <br />advantageous to check the hydraulic operating characteristics of culverts <br />during ar immediately after heavy rainstorms. Because of the special <br />scheduling considerations previously mentioned, culvert inspection schedules <br />must contain flexibility. <br /> <br />4-2.5 Recording the Inspection. <br /> <br />When inspecting culverts, information will usually be recorded by a variety of <br />methods including standard forms, standard prepared sketches, narrative <br />descriptions, and photographs. Collection methods include the following: <br /> <br />a. Inventory Data--A standard inventory card or form should <br />record basic information such as location and structure type. <br />inventory form was shown in exhibit 32. <br /> <br />be used to <br />A sample <br /> <br />b. Standard Inspection Report Forms--Standard inspection report forms are <br />usually the most convenient method for recording specific items of information <br />such as numerical data and brief descriptions or remarks. Properly designed <br />forms can provide assistance in field data collection by providing a list of <br />the items that must be evaluated or measured and can also organize data, <br />making it more accessible for review. Because very few of the items on bridge <br />inspection forms apply to culverts, it is highly recommended that forms <br />developed specifically for culverts be used to record culvert inspection <br />results. A sample culvert inspection report form is shown in exhibit 33. <br /> <br />The form shown is basically an adaption and expansion of the SI&A condition <br />rating items that apply to culverts. Numerical ratings are used to record the <br />condition of each item and rating systems are described in section 3 of this <br />chapter. The expanded SI&A items provide information that identify the <br /> <br />51 <br />
