REPORT SUMMARY
UNDERWATER INSPECTION
The substructure units inspected at Bridge No. 57518, Piers 1 and 2, were found to be in good condition with no defects of structural significance observed. The channel bottom consisted of sand which was well established and appeared stable with no evidence of scour.
(A) The 16 inch diameter pile encasements of Piers 1 and 2 were coated from top of pile to the channel bottom. The piles typically have no loss of coating from top of piles down 5 feet. From 5 feet below the top of the pile to the channel bottom, the piles have loss of coating over up to 50% of total surface area. In the areas of coating loss, the piles have random areas of minor surface corrosion with no appreciable section loss.(B) Pier 1, Pile B (second pile from the south) has hollow sounds at west face, 3 feet high, starting 6 feet below cap.(C) Pier 1, Pile E (second pile from the north) has hollow sounds at west face, 4 feet high, starting 5 feet below cap.(D) Pier 1, Pile F (northern most pile) has hollow sounds at west face, from 6 feet below cap to ground line.(E) Light to moderate accumulations of timber debris and organic material were observed around Piles C through F of Pier 1.

The superstructure consists of three spans of multiple precast concrete beams supporting a reinforced concrete deck. The superstructure is supported by two reinforced concrete abutments and two concrete filled steel pipe pile piers. The piers are numbered 1 and 2 starting from the west end of the bridge. No design drawings were available.

The routine underwater inspection of Bridge 57518 (CSAH No. 3 over the Red Lake River) was completed on September 27, 2016. The underwater inspection was conducted from shore. The inspection was conducted by a team consisting of a PE-Diver with a valid MnDOT Team leader certification, a backup diver and a dive tender. The inspection utilized commercial dive equipment and techniques (SSA and/or SCUBA) in accordance with OSHA regulations. Profiles were taken along the upstream and downstream faces of the bridge and around the periphery of substructure units to determine the presence, location and area of scour.
The bridge elements inspected consisted of two piers each consisting of a single row of six concrete filled steel pipe piles. According to the bridge inventory or design drawings, the piles support a rectangular reinforced concrete pile cap with rounded ends. Inspection procedures followed FHWA guidance and the MnDOT Bridge and Structure Inspection Program Manual with channel bottom probing to search for foundations. The routine underwater inspection frequency is recommended to remain at 60 months based on those findings and risk factors. Also, inspection procedures should continue to follow the above approach and standard guidance with 100% Level I and 10% Level II intensity efforts.
