12 Tr. 1841. In fact, the subcontractor, R. H. Fulton, did not commence laying operations (66'' pipe) until September 2, 1964 (Tr. 1841 ; Inspectors Dally Report, dated August 27, 1964). By September 21, 1964, the supply of 66-inch pipe had been exhausted and R. H. Fulton skipped a section of the line and commenced laying 54-inch and 60-inch pipe (Tr. 1842).

14 Letter, dated October 30, 1964, Exh. 9. These statements are attributed to Mr. S. R. "Duke" Hubbard, vice president and general manager of Cen-Vi-Ro (Tr. 1095). The Board finds that the letter accurately reflects events at the meeting (Tr. 563, 677, 1844).

15 Mr. Franklin testified that the gyro spinner was essentially out of production from September 1, 1964, to January 1, 1965, for modifications and machining of forms which were sent to Fort Worth and Los Angeles (Tr. 559). A total of 760 pipes had been produced on this spinner by November 16, 1964

(Tr. 1862). While the gyro spinner had previously been used for the manufacture of 32 miles of 87-inch X 40-foot pipe for the East Bay Municipal Utility District (Oakland, California), this was not RCP pipe (Tr. 565, 566, 595). Mr. Franklin expressed the opinion that the machine was capable of producing good quality pipe under proper supervision, i.e., skilled operators (Tr. 614).

16 Mr. Franklin stated that production during this period was sometimes curtailed awaiting additional forms (Tr. 562). This testimony is confirmed by a memorandum from the resident engineer dated October 22, 1964 (Exh. S) and Inspectors Daily Reports, dated August 3, September 11, 21 and 26, and October 16, 19, and 20, 1964.

23 "Substantially less than the pipe length" does not appear to have been clearly defined until the chief plant inspector's memorandum of March 31, 1966 (Exh. 5N, pp. 32, 33) which appears to be limited to reclaims and which after referring to Cen-Vi-Ro's contention that pipes which dripped on the test stand would heal within seven days and to an amendment to Subparagraph 67.j.

Engineer's letter of January 20, 1965, provides in pertinent part as follows:
