This condition is not a problem <br />at this time and is noted for future reference. The timber columns were probed with an ice pick and sounded to access their condition. <br />The bottom timber lagging at Abutment 7 between Piles 1 and 2 is starting to decay. <br />Defect is meant to capture the gap in the timber lagging at Abutment7 between Piles 1 and 2. The gap is 2 inches high and 5 feet in <br />length and is between the lowest and second lowest row of timber lagging. Refer to Photo 5. <br />There were no significant defects noted. <br />There are horizontal checks up to 9 feet long by 0.25 inch wide along the timber cap at Bents 2, 3 and 6. This condition is not a <br />problem at this time. Refer to 2018 BIR photo number 4. The location and size of these defects has not changed since that photo <br />was taken. The timber bent caps were probed with an ice pick and sounded to access their condition. <br />The following girders were replaced in 2019 with 3 inch x 15.25 inch timber beams: <br />Girder 1 (left exterior) in Spans 3, 6 and 7. <br />Girder 1 (right exterior) in Spans 1 through 4 (all the way from Abutment 1 to Bent 5) and in Span 7. <br />Girder 4 of Span 7 is supplemented by a 4 inch x 15.5 inch stringer. <br />The previously noted water infiltration through the AC on the deck has begun to cause decay in the timber planks and some timber <br />blockings. The AC has been repaired and the planking will continue to be monitored.
