Tudor Submittal File 00730 Section 11257: Speed Increaser =============================== Voith did not submit speed increaser "shop drawings" and nearly all of the sub- mittals it did make were over a year late and were rejected by Tudor enmasse.
This is shown in one of Tudor's green "Contractor Transmittal" forms dated March 28, 1989, which shows most of the speed increaser submittals in the jobsite files (set out below) were received by Tudor on Feburary 15, 1989, and were returned marked "Revise and Resubmit" on the grounds that they "need English translation." There is no record Voith complied with the Engineer's directive to re-submit or that Tudor approved Voith's speed increaser submittals.
There are no due dates in Tudor's submittal log for the Voith contract. "Due" dates entered in this format (shown below) are taken from the Nov 3, 1987 meet- ing minutes which appear to be based on a Renk submittal schedule attached to those meeting minutes.
There are no indications in the record so far that Tudor directed Voith to com- ply with contract submittal and scheduling requirements. Failure to post "due" dates in the submittal log hid Voith's failure to perform until it was too late, resulting in the summary rejection of March 28, 1989 (discussed above).
There is not a one-for-one correlation with respect to submittal descriptions between the sources for the submittal information shown below, mainly with respect to "Due" dates, since Tudor did not post any.
The order shown below is that shown in Tudor's jobsite files.
Tudor Contractor Transmittal File No. Rv Date Drawing No. Title/Description Due Received Returned St -------- -- -------- ------------- ----------------------------- -------- -------- -------- -- 11254.59 00 02-18-88 None Renk AGMA/Life Cycles cale 11-23-87 02-19-88 03-04-88 A
This appears to be the item on Renk's Sep 8, 1987, submittal schedule titled "Final AGMA 218 and Lifetime calculations" which Voith seems to have scheduled in the Nov 3, 1987 meeting for Tudor to receive on Nov 23, 1987, but which was actually received on February 19, 1988.
This was about 90 days late.
This submittal is missing from Tudor's jobsite files.
There is also no Tudor green "Contractor Transmittal" for this item which should have been prepared on March 4, 1988. It is not in the file.
Conflicts with Tudor 11257.02 ----------------------------- Tudor notes in returning Renk's "Mass Scheme" submittal (11257.02 shown below) that Voith must submit specified AGMA information. Since the "Renk AGMA/Life Cycles cale" submittal (11254.59) was received on Feburary 19, 1988, then, if it adequately addressed all AGMA data issues there would have been no need to request AGMA data on transmittal 11257.02 just 3 days later.
Accordingly, it seems likely that this submittal for 11254.59 did not satisfy the request Tudor made for more AGMA data on submittal 11257.02. Since the submittal is missing from Tudor's jobsite files, the extent of Voith's compli- ance with AGMA standards is not known.

This drawing appears to be in Tudor's jobsite files with a received stamp on the back of Feb 4, 1988. It seems to be the Renk submittal identified on its Sep 8, 1987 message titled "Information of masses of inertia and flexible lengths" and appears to have been included in the single item on the Voith submittal list of Nov 3, 1988 titled "Foundation Loading Data" which was to have been received by Tudor on November 23, 1987.
It was approximately 70 days late.
AMGA Data Requested ------------------- It has another Tudor stamp on the back with respect to disposition that seems to show a date of 2/29/88, with a comment:
Submit design calculations in accordance with AGMA standards. There is a comment below this comment:
Rec'd submittal #16. This appears to be initialed beginning with "D" but the other initials are unclear.
It is also unclear whether the requested data was actually received. See also discussion above for 11254.59 under "Conflicts with Tudor 11257.02."
Tudor Contractor Transmittal File No. Rv Date Drawing No. Title/Description Due Received Returned St -------- -- -------- ------------- ----------------------------- -------- -------- -------- -- 11257.03 00 1-18-88 2693-0002 0 Renk Outline dwg (3200557/0) 11-15-87 02-19-88 03-04-88 D
This drawing appears to be in Tudor's jobsite files with a received stamp of Feb 19, 1988. It has another Tudor stamp on the extreme left side that seems to show a date of 2/1/88, but indicates "Revise and Resubmit."
The drawing has many notations showing it does not comply with Tudor specs. See below for possible re-submittal.
This appears to be the drawing on Renk's Sep 8, 1987, submittal schedule titled "Final outline drawing" which Voith appears to have scheduled in its Nov 3, 1987 meeting minutes to in Tudor's office on Nov 15, 1988.
Tudor shows this submittal to be "Revised and Resubmitted". There is no subsequent entry where this drawing was resubmitted and approved for construction.
Corrected Drawing ----------------- There is another drawing numbered 3200557/0 with Voith number 2693-0002 Rev 03. It shows a "Tudor-no: 11257-03.03" in the ID block, and is stamped "Received Feb 21, 1989" by Tudor in San Francisco. It is stamped received by Voith "5/24/88."
Tudor Submittal --------------- There is a separate green "Contractor Transmittal" document in Tudor's jobsite file #00730 which lists this submittal as "2693-0002 Renk Outline Drawing." It is marked as received by Tudor on Feb 15, 1989, rather than Feb 21, 1989, so it may correspond to this submittal even though the received dates do not exactly correspond. Tudor also marks this submittal by Voith as "Revise and Resubmit."
This drawing contains some of the corrections noted to be made on the submittal Tudor received on Feb 19, 1988. For example: Was Changed to ------------- ------------------------ Runaway speed n=232 RPM n=252 RPM High Pressure Oil inlet line showed for oil quantity _______ ~2.65 US galns. min. * Position of "dials" Not Viewable Moved somewhere Errors Not Corrected -------------------- Tudor notes 1 - 4 above on the original submittal do not appear to be reflected in this second submittal which was received by Tudor Feb 21, 1989, 3 months after the Speed Increaser was delivered to the job. As noted above Tudor has a Transmittal dated March 28, 1989, in which this submittal is marked "Revise and Resubmit." There is no record this was done.
