Pro'ect Desc�iption and Purpase, . iF�e pro�ect consists of the inskal�ation of 72-inch and 9p-inc� diarneter, 23,OQ0 foat long sanitary sewet' plpeEine. The sanitary sewer main alignment is generafly Iocated from the Village Creek 1NWTP sout� ko I-iighway 80. The project Enc�udes abovt 33 maC�hole structures and �6 ta 20 ot�er major structures including siphons and special �oxes. Five lo�g sewer bores are presentEy planned at tF�e tolfowing lacatiot�s: Along Meadowbroak Bkyd and across Vilfage CraeK, I-30, Dotkie Lynn Parkway a�c# Highway 180. Ti�e purposa vt the �roposed investigation will be to evaluate su�surface canditions alo�g the alignmer�t; pro�ide recommendations regarding pipe embedment and destgn of the structures; and evaluate tne carras�on pot�ntial on cone�'ete strt�ctures and pipes. Geot�chnica! Fie1d Envestiqatio�, Based on TM1's site vicinity experience th� sit�: is lacaked 1n the 1Noadbine Farmatian. Thas farmation is highly variable with soi! materi�ls varying from sands ta clays. Tk�e rock forrr�ation consists of cemented sands and shale typicaify at de,�ths of 20 feek or more. Very hard sandstvne can be encountered a�ove the shale. In accardance �viti� y�ur �equest, a iotal af �6 �orings are planned. Roring depths rar�ge from about 2a tv 55 feet below existing grade. The general boring locations and depths have bee�� selected �y TranSystems. The bvring depihs have been sefected ta provide a depth of exploratian to a m�nimum depth of 5 iest be�aw t�e bottom of tt�e pipe andlor structure. 2400 Gr9v$t Drlva, Bldg. 25� �ort Worth� Texaa 7611 B phone: B97-Z8d-9383 I�ax: 817-284.9430 , �. ��.�.�-�� . iMl Proposal Na.
