Dear Mr. Hirschey:
We must take exception to Mr. Durbin's letter of April 4, 1989
regarding the grout between the carrier and encasement pipes on
the 36" influent line. The detail on Sheet SD17 is quite
specific on the need for and location of grout inside the casing.
The placement of grout on this project is not per our direction,
it is per the requirements of the Contract Documents signed by
Cajun Contractors, Inc. for this project.
As for the welding of joints at certain bends on the influent
line, we strongly encourage you to investigate this possibility.
Adjacent utility conflicts and the location of the waterline may
not allow sufficient room for the thrust blocks to be contained
within the easement as required. Your vendor, United Concrete
Pipe Corporation, can provide the necessary description,
technical guidance, and quantity of welds required to restrain
thrust at any bend along the pipeline.
Please feel free to contact us if you have any questions.
Sincerely,
Sanford W. Case,
Project Manager
