Re: THE WORLD TRADE CENTERi-, Dey Street Underpass

Dear Mr. Novotny;

All the revisions you-drequested in your October 8, 1981 letter to me have been incorporated into l^lity Agreement Drawing Nos. WTC-Cl through WTC-C7-81, except as follows.

Generally, specific d'eteails of sewer manholes, cradles, casings and subsoil conditions as well as sjBnilar elements of construction for participating utility companies have been omitied since the above drawings are only required to establish the lanes for eachedf-the relocated utilities. Upon receipt of your approval, we will complete detailed Contract Drawings and submit them to you for approval. Note #1 of tHe'General Notes on Drawing No. WTC-C3-81 con firms this procedure.

I understand that wherSii^er Con Edison 'Steam lines affect the sewer system they also will submit Conslwract Drawings for your review and approval.

The following are speoifrc references to the comments in your October 8th letter using the saraenhitem numbers.

1. Drawing No. C-4 has begii revised to show 4'-2" clear between the building and the steampi^pe casing. Class 56 ductile iron pipe on a Class "35" concrete (Siradle. Additional detail as noted alsove will be included in thejrfinal Contract Drawings.

2. A complete profile of jlth.e rerouted 18" sewer is provided on a new drawing, WTC-C7-81.

3. As you suggested, we attfeempted to redesign Manhole #3 as an "L"- shaped manhole but concaluded that adjacent construction rendered that method impracticakr We therefore returned to the original design with entrance t.certhe sewer at the existing manhole. In a previous submission, you did not object to this method.
