This report summarizes our threshold inspection services performed during the inspection period of July 27, 2020 through July 31, 2020. Inspections took place on July 28, for a pre-final inspection for threshold related items. Our inspections were performed in accordance with the structural documents, signed, and sealed by the Engineer of Record, Luca DelVerme PE (AVCON INC), and the project specifications. Our special inspector and his duly authorized representative(s) reported their observations as noted on the attached Daily Threshold Reports with all structural non‐compliance items noted within the attached Special Inspection Log (SIL). All non‐compliance items, or SIL’s, previously reported as non‐compliant with regard to the plans or specifications, will be reevaluated by our Special Inspector after corrective action is taken by the General Contractor or the deficient conditions have been approved through written approval by the Engineer of Record. During the inspection period of July 27, 2020 through July 31, 2020, and to the best of our knowledge and belief, the construction of all structural load‐bearing components described in the threshold inspection plan complies with permitted documents, with revisions as approved by the Engineer of Record, except as noted on the SIL. Should you have any questions or concerns regarding these reports, or desire any additional information, please contact us. Sincerely, AVCON, Inc. Certificate of Authorization No. 5057 Rick V.

This has been corrected, however, corrosion at the upper beams, as well as sand that is still packed into the steel, will close this entry and create a new entry, see SIL Log #8. See Exhibit "A". Steel columns still have gaps under the base plates. Grout has been placed in several of the problem areas. See SIL log, #5. This issue has not been corrected, and mud and other debris has entered into these areas. See Exhibit "B". Some bolts were not secured in place, even by hand tightening. SIL log entry, #6 is still ongoing. - THIS ITEM HAS BEEN CORRECTED IN SEVERAL AREAS, AND THE LOG ENTRY WILL REMAIN, BASED ON OBSERVATIONS - See Exhibit "G" and notes below. Observed standing water in the hangar door track. Rail drainage is not currently tied into any system, and does not drain. See SIL log for new entry, #9, for potential salt water corrosion. See Exhibit "D". Roofing installation is still ongoing and still in process. Southern connection was not installed. Some areas needed to be corrected, by having fasteners/screws re-installed. The gutter system is not part of the inspection, but can affect the building, and was observed to have numerous bent connections at the "gutter support". See Exhibit "E". The beam connections have many "daylighting" areas within them. This will be a new entry, unless the engineer or shop drawings can be shown as to where this is acceptable, see SIL Log #10. See Exhibit "F". Several bolts were too short. This happened often where more than one piece of steel was connected. See SIL Log #6 will remain, and Exhibit "G". Expansion joints to the north of the hangar door have been damaged, and will need to be repaired prior to completion. See Exhibit "D". Plastic shrink cracking has occurred at the tracks for the hanger door. See SIL Log #12, and Exhibit "H".
