Bridge Name: WSF High Level Bridge File No.: 131M Inspector: Ainalem Molla Co-Inspector: Pablo Zuleta Equip. Used: Flashlight, crack gauge, marking chalk, UBIT Hours on Site: 3.0 Weather: Clear Date: 05/20/2015 . Scope of Inspection: An Inspection of the segmentally cast in place, post tensioned, box girder from the interior. . Findings, Location of Defects, and Recommendations . General - This inspection was scheduled to check if 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 are reflected in the interior. They were not last year and are visible on the inside this year. Access was provided through the manhole located in the westbound center lane shoulder at Pier 16. Confined Space procedures were used. Non-Permit Required. Fall Protection procedures were used for entry. . All six sections of the box girder have shear cracking in the soffit of the deck at the ends of each section. Continue to observe. . 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) . 3. 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 promenant 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 promenant leak is at the west most fire hydrant wye and at a pipe joint 50 linear feet to the east.
