Call crew to use the green fall protection system. * Pier 15 is west end of 131M. Pier 18 is east end of 131M. There are 35 segments in the main span, including the pier tables. * At Pier 15 and 16, the fence around the pier is damaged from truck trailers. Continue to observe (CTO). . Falcon nest on pier 15. The falcons were hovering over during the 2019 inspection to protect their next. It probably shows there were babies in the next.. . * See 131WA and WR for west approaches and ramps. * See 131EA and ER for east approaches and ramps. 3 11/14/19 - Interim Inspection by MD & AM The scope of this interim inspection was mainly focused on checking recently epoxy injected cracks for any signs of re-racking. Box girder segments 37 and 38 were the main area for this inspection. UBIT was used for access starting in the west bound direction for the north box and eastbound direction for the south box. Tools for inspection included flash light, camera, magnifying glass, tape and crayon. See also pictures in the O drive for this inspection. * All injected cracks on both boxes were checked and no apparent recracking was found. * There was a smudged surface with epoxy that looked to have leaked through the sealed cracks at a small area of the east side of north box. The area covers about 3' long 10"+/- wide. The epoxy felt tacky to touch. No apparent cause except to assume the mixer was not working right. It is marked with a crayon to be checked later in the next inspection. * The spacing of the crack injection ports varied along one line of injected crack. Perhaps the crews hit rebar and had to relocate the port position. This may indicate that at some locations injected epoxy was limited to a shallow depth. * At the bottom of the north face of the south box at about the mid line of the navigation canal, there is a long but narrow stretch of rock pocket that is filled with loose sand. It is about 5 feet long and about 1"+/- wide. See work order # 788109 * There are also few smaller, less significant cracks that were not epoxy injected. ________________________________________________________________ Special Inspection Notes from 2019 inspection . Bridge Name: WSF High Level Bridge File No.: 131M Inspector: Ainalem Molla along with equipment operation Co-Inspector: Kit Loo Used: Flashlight, marking chalk, UBIT Hours on Site: 5.0 Weather: Clear Date: 05/30/2019 . Scope of Inspection: An Inspection of the segmentally cast in place, post tensioned, box girder from the exterior side. Findings, Location of Defects, and Recommendations General - This inspection was scheduled to check and monitor the transverse cracks on the outside of the bottom of the main span at the 11th and 12th panels East of Pier 16 and the 11th panel West of Pier 17 in both south and north boxes. The cracks at the west side of the north span were sealed along with injection ports and ready for crack injection. The cracks are not getting wider but the number has increased. The cracks are remotely monitored in real time and there is no big change in the size except for a small fluctuations. The cracks that are greater than 0.005" were marked for epoxy injection in the south box at both west and east sides of the span. The fire suppression system supply pipe has vertical hangars and horizontal brace rods with turnbuckles. Typical in all box sections: The vertical hangars do not appear to be vertical. The horizontal braces are mostly bent and there is at least one that is broken. See Work Order #160505. . South Box, West End . 1. Pier 16, west diaphragm, there are four longitudinal cracks with efflorescence visible in the top deck soffit. Continue to Observe (CTO) . 2. Pier 15, end diaphragm, the earthquake restrainers indicated approximately 3 ½ inch of movement between anchor rod and restrainer plate. This is visible by looking at the rods for evidence of movement. (CTO) . BRIDGE INSPECTION REPORT Status: Released Printed On: 3/24/2020 CD Guid: 85f9992d-48a3-421e-a293-20769ad4b300 Br.

Minor Transverse Leaching Cracks in box top soffit, located approx. 40 feet east of the end diaphragm. . 4. Nine longitudinal cracks approximately 80 feet east of the west end diaphragm. Each crack is approx. 3 feet long. They are located in the box top deck soffit and within a closure pour. (CTO) . 5. Typical throughout, small cold joint crack like openings occurred during construction and were filled by epoxy injection. These areas did not show any signs of recent cracking. (CTO) . The watermain pipe hangers and supports have been damaged through out the box girder. The damage is most prominent at pipe hangers and supports near the wye fittings, which feed the fire hydrant runs. The vertical pipe hangers (Type I on plan sheet 20 of 100) are bent and show signs of stress, while the horizontal pipe hangers (Type II on plan sheet 20 of 100) show signs of stress and some have buckled. This has resulted in several water leaks at the victaulic groove joint fittings. The most prominent leak is at the west most fire hydrant wye and at a pipe joint 50 linear feet to the east. . South Box, Main Span 6. Typical, there is an intermittent crack or cold fissure located in the re-entrant corner between the box web and box top deck. It appears to be construction related. (CTO) . At all tendon anchorage steps there are hair line cracks from the box girder walls toward the center of the box at approximately a 45° angle. The cracks vary in width from 1/64" to 1/8".
