Project costing $14 million, comprising of 4 viaducts 280 to 320 feet long, 2 frames and 7 to 9 spans with middle hinges.  They are built as 20-foot widening to existing roadway with complicated horizontal and vertical curves.  They consist of 20-inch reinforced slabs on grade supported by 24-inch CIDH piles. Service Date – April 2021 to Sep  2021.  As Assistant Structure Representative and Roadway Inspector.

Responsibilities include:

  1. Computing finish grades for abutments, hinges, top and bottom of slabs, pile cutoff and top of pin.
  2. Computing and verifying on site the rebar cage lengths of CIDH piles.
  3. Witnessing testing of rebar couplers for deck slabs and concrete barriers.
  4. Measuring and recording in as-built plans the types and locations of all rebar couplers in deck slabs and concrete barriers.
  5. Maintaining the CIDH pile logs, recording start, finish and progress of installation in addition to installation problems including depths of water intrusion, location and depth of caving, slurry backfill and re-drill, grout leakage into river, signs of insufficient dewatering causing contamination of concrete with mud sludge.
  6. Measuring and agreeing with contractor field measured quantities immediately after the completion of the item work, and this is accomplished with signed agreement with contractor and documentation in diaries.
  7. Writing diaries, maintaining concrete pour records and documentation for material release tags, and preparing as-built plans.
  8.
