 As was stated at an earlier date. We are unable to complete our take off work on the bridge widening for the Northeast Connector due to the lack of deck elevations being shown on the drawings.

Q:06/19/03
    R:06/25/03
Plan Sheet / Specification Reference=75 2.1 m CIDH Concrete Piling.

The response to Question 7 states that no construction joint will
be allowed.  It will be impossible to place both the pile and column
reinforcement and concrete the pile within a single 24-hour period.  Will
the requirement to place concrete within 24-hours of rebar placement be
relaxed in light of the response to Question 7? 

  • The response to Question 7 is "No construction joint is allowed below the plane of pile cut-off that is 305 mm below O.G."  A construction joint is allowed at the plane of pile cut-off.  Please provide further clarification including a reference (page and paragraph numbers) for the noted phrase  "place concrete within 24-hours of rebar placement" so that we can respond to your question.
