Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
83 This Appendix contains examples of 24 forms that may be useful in documenting the various stages of forensic investigations. Use of the forms and the level of detail captured will depend on the specific investigation, the level of detail required, and the level of information needed for implementing the findings. These forms can be modified to suit specific agency requirements (Microsoft Word® fillable forms and instructions on how to modify them are included in the attached CD at the end of the report). The forms and the section in the guide in which they are referred to are: Form #1: Forensic Investigation Request (Section 3.1) Form #2: Preliminary Investigation (Sections 3.5.1 and 3.5.2) Form #3: Decision to Proceed (Section 3.5.3) Form #4: Preliminary Investigation Report (Section 3.6) Form #5: Forensic Investigation Team (Section 4.1) Form #6: Pre-Investigation Site Visit (Section 4.2) Form #7: Photograph Record (Section 4.2) Form #8: Visual Assessment Form (Asphalt/Surface Treatment) (Section 4.2.1) Form #9: Visual Assessment Form (Portland Cement Concrete) (Section 4.2.1) Form #10: Initial Non-Destructive Testing Plan (Section 4.2.4.4) Form #11: Initial Forensic Investigation Plan (Section 4.4) Form #12: Interim Report Cover Sheet (Section 5.3) Form #13: Final Non-Destructive Testing Plan (Section 6.1) Form #14: Destructive Testing Plan (Section 6.1) Form #15: Final Forensic Investigation Plan (Section 6.1) Form #16: Forensic Investigation Site Report (Section 7.2.1) Form #17a: Core Log (Single Core) (Section 7.3.1.2) Form #17b: Core Log (Multi Core) (Section 7.3.1.2) Form #18: Test Pit Profile (Sections 7.3.2.2 and 7.3.2.3) Form #19a: Asphalt Concrete/Asphalt Surface Treatment Layer Log (Section 7.3.2.2) Form #19b: Portland Cement Concrete Layer Log (Section 7.3.2.2) Form #20: Gravel and Stabilized Layer Log (Section 7.3.2.2) Form #21: Sample Log (Section 7.3.2.4) Form #22: Density and Moisture Content (Section 7.3.2.4) Form #23: Dynamic Cone Penetrometer (Section 7.3.2.6) Form #24: Final Report Cover Sheet (Section 8.2) Examples of selected forms are provided for Case #2 in Appendix B.
