Most of <br />the soffit <br />area has <br />surface <br />corrosion. <br />Refer <br />to <br />photo numbers <br />3 and 4. <br />, <br />170 <br />Railroad Car Frame <br />2 <br />34 m <br />0 <br />33 <br />1 <br />0 <br />1000 <br />Corrosion <br />2 <br />30 <br />0 <br />29 <br />1 <br />0 <br />1010 <br />Cracking <br />2 <br />4 <br />0 <br />4 <br />0 <br />0 <br />515 <br />Steel Coating -Paint <br />2 <br />152 sq.m <br />50 <br />0 <br />102 <br />0 <br />3450 Paint Sys Breakdown (Steel PC) <br />2 <br />102 <br />0 <br />0 <br />102 <br />0 <br />(170-1000) <br />The outside faces of the outer girders of the railroad cars are protected with green paint. The <br />remaining surfaces of the railroad cars have active corrosion, pitting, flakes, and are brownish <br />color. The bottom surfaces of the lower flanges of the main girders have the most pitting and the <br />paint system has almost completely flaked off. The longitudinal girders and their web stiffeners <br />have active corrosion and pitting. The transverse beams have active corrosion on their surfaces. <br />Section loss from active corrosion and pitting is less than 1 percent on both railroad cars. <br />(170-1010) <br />The following cracks have been noted in BIRs dating back to 12/03/2003 and there was work done to <br />weld over these cracks. The sizes of these cracks have not changed since they were first noted. The <br />following notes are retained for future reference to check crack propagation: <br />1. A 3.75 inch crack in the web of the main girder of the left railroad car in Bay 1 at midspan. <br />2. A 4.30 inch crack in the web of the main girder of the left railroad car in Bay 2 at midspan. <br />3. A 2.4 inch crack in the web of the main girder of the right railroad car in Bay 3 at midspan. <br />4. A 3.5 inch crack in the web of the main girder of the right railroad car in Bay 4 at midspan. <br />(170-515-3450) <br />The green paint on the outside faces of the outer girders of the railroad cars is chalking and faded. <br />The paint on the remaining surfaces of the railroad cars has failed. Refer to photo numbers 3 and 4. <br />215 Abutment -RC 2 12 m 12 0 0 0 <br />(215) <br />The top of footing is exposed up to 1 foot vertically along the entire length of the old Abutment 2. <br />There is undermining along an 8. foot section at the left side of Abutment 2. This finding is <br />structurally insignificant because the superstructure is seated on new abutments behind the old <br />abutment locations. <br />304 Joint -Open Expansion 2 12 m 12 0 0 0 <br />(304) <br />There were no significant defects noted. <br />311 Bearing -Moveable <br />1000 corrosion <br />(311-1000) <br />The bearing areas have pack rust. <br />313 Bearing -Fixed <br />1000 Corrosion <br />2 <br />4 each <br />0 <br />0 <br />4 <br />0 <br />2 <br />4 <br />0 <br />0 <br />4 <br />0 <br />2 <br />4 each <br />0 <br />0 <br />4 <br />0 <br />2 <br />4 <br />0 <br />0 <br />4 <br />0 <br />Printed on:Wednesday 03/04/2020 08:15 AM 29C0413 /AAAM/57893 <br />
