Finally something is happening on site! This project might actually get built.
Great! Look who showed up on site. This guy’s wife was noticed spawning 75’ up stream. Job was shut down immediately per Fish and Games request. The evaluation process took 2+ weeks until environmental agencies were satisfied that eggs would not be harmed.
Not such a great idea anymore. Even if they had used a bond breaker behind the steel this would be difficult to remove. This was not repeated on the second abutment. They used plywood for the next template.
INITIALLY WANTED TO DO 1 CONRETE POUR PLACE ABUTMENTS ATTACH WING WALLS SET GIRDERS POUR CONCRETE
DECIDED THAT 2 CONCRETE POURS WOULD BE EASIER TO CONSTRUCT PLACE ABUTMENTS POUR CONCRETE CLOSURES AROUND PILES IN ABUTMENT ATTACH WING WALLS SET GIRDERS POUR CONCRETE DIAPHGRAMS AND WING WALL CLOSURES
Even with predrilling it’s not easy. These 10” piles need to fit in a 24” CMP.
PBES DID LOWER THE ENVIRONMENTAL RISK ON SITE DO NOT USE STEEL PLATE FOR REBAR TEMPLATES WHEN PRE-CASTING WHEN TAPERED INSERTS ARE ALLOWED THEY SHOULD BE PROTECTED IT’S NOT EASY TO CHANGE CURRENT INDUSTRY PRACTICE
PBES REDUCES THE POTENTIAL FOR MISTAKES IN THE FIELD AND REQUIRES CONCRETE PLANT CERTIFICATION— CONTRACTORS IN THE FIELD DO NOT REQUIRE CERTIFICATION PILE DRIVING MAY BE A FOCUS AREA WITH PBES ESPECIALLY WHERE DIFFICULT PILE DRIVING IS EXPECTED MORE DETAIL IN CONSTRUCTION SPECIFICATIONS MAY BE NECESSARY TO CONTROL ITEMS SUCH AS WHEN BACK FILL OPERATIONS SHOULD OCCUR
