Contractor:

(A) Scour screening assessment indicates stable rating and the extent of foundation exposure has not increased since the previous inspection, therefore, presently it is only recommended to monitor the extent of scour and footing exposure during future inspections.

(B) Consider removal of the accumulated timber debris around the piers during routine bridge maintenance.

(C) Reinspect the submerged substructure units at the normal maximum recommended (NBIS) interval of sixty (60) months.

REPORT SUMMARY

UNDERWATER INSPECTION

The substructure units inspected at Bridge No. 73540, Piers 2, 3, 4 and 5, were found to be in good condition with no defects of structural significance observed. Minor deficiencies observed included, random areas of poor consolidation with ¼ inch maximum penetration. Footing exposure was observed at the upstream end of Piers 4 and 5. The extent of footing exposure was comparable to what was reported during the previous underwater inspection. A light to moderate accumulation of timber debris was observed around the entire perimeter of Piers 2 and 4, and at the upstream end of Pier 3. The channel bottom appeared stable with minor localized scour observed, with no appreciable changes since the previous inspection.

(A) The channel bottom material generally consisted of sandy gravel and random cobbles allowing a maximum probe rod penetration of 6 inches.

(B) The channel bottom material consisted of silt allowing a maximum probe rod penetration of 2 feet at the upstream end of Pier 5.

(C) Footing exposure was observed at the upstream end of Pier 4, extending approximately 8 feet downstream on the east and west sides of the pier with a maximum vertical face exposure of 2.5 feet at the upstream nose.

(D) Footing exposure was observed at the upstream end of Pier 5, extending approximately 15 feet downstream on both sides of the pier, with a maximum vertical face exposure of 3 feet at the upstream nose.

(E) A light accumulation of 8-inch-diameter and smaller timber debris was observed around the entire perimeter of Piers 2 and 4 extending from the channel bottom up 6 feet and up to 3 feet off the pier noses and faces.

(F) Minor scour depressions, typically 5 feet in radius and 2 to 3 feet deep, were observed around the upstream ends of Piers 3, 4, and 5, resulting in footing exposure at Piers 4 and 5.

(G) The submerged concrete of the piers and exposed footings was in sound condition with minor random areas of poor consolidation with 1/4 inch maximum penetration.

(H) A light accumulation of timber debris, consisting of up to 8-inch-diameter branches, was observed at the upstream nose of Pier 3 from the channel bottom up 2 feet. The debris was approximately 8 feet long (E/W) by 3 feet wide (N/S).

The superstructure consists of seven spans of multiple prestressed concrete beams. The superstructure is supported by two reinforced concrete abutments and six reinforced concrete piers. The piers are numbered 1 through 6 starting from the west end of the bridge. The footings of all the substructure units are supported on steel H-piles.

The routine underwater inspection of Bridge 73540 (10th Street Bridge (MSAS No. 101) over the Mississippi River) was completed on September 30, 2016. The underwater inspection was conducted from a 21 foot boat. 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 four reinforced concrete piers each with of two flared columns extending down to form a single oblong rectangular shaft. According to the bridge inventory, Piers 2 through 5 were supported on rectangular concrete footings founded on steel H-piles. 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 a maximum of 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.
