A. 
Preparation.
(1) 
Perform trench excavation and associated work as specified in Article VII.
(2) 
Provide pipe bedding (Type III or IV) as specified in Article VII. Place aggregate so that the pipe can be laid to the required tolerances.
B. 
Laying pipe in trenches.
(1) 
Give ample notice to the municipality in advance of pipe-laying operations, minimum 24 hours.
(2) 
Lower pipe into trench using handling equipment designed for the purpose to assure safety of personnel and to avoid damage to pipe. Do not drop pipe.
(3) 
Lay pipe proceeding upgrade with the bell or groove pointing upstream.
(4) 
Lay pipe to a true uniform line with the barrel of the pipe resting solidly in bedding material throughout its length. Excavate recesses in bedding material to accommodate joints, fittings and appurtenances. Do not subject pipe to a blow or shock to achieve solid bearing or grade.
(5) 
Lay each section of pipe in such a manner as to form a close concentric joint with the adjoining section and to avoid offsets in the flow line.
(6) 
Clean and inspect each pipe and fitting before joining. Align pipe with previously laid sections. Assemble to provide tight, flexible joints that permit movement caused by expansion, contraction, and ground movement. Assemble joints in accordance with the pipe manufacturer's instructions.
(7) 
Check each pipe installed as to line and grade in place. Correct deviation from line and grade immediately. A deviation from the designed line or grade as shown on the drawings will be cause for rejection.
(8) 
Place and compact sufficient backfill to hold each section of pipe firmly in place as the pipe is laid.
C. 
Backfilling trenches.
(1) 
Backfill pipeline trenches only after examination of pipe by the municipality.
(2) 
Backfill and compact trenches as specified in Article VII.
D. 
Pavement base drains and pipe underdrains. Construct drains of the size and type indicated on the drawings in accordance with the requirements set forth in Section 610, Publication 408, Specifications, and as shown on Standard Drawing RC-30, Publication 72M.
E. 
Surface restoration.
(1) 
Restore unpaved areas in accordance with Article VII.
(2) 
Restore other areas in accordance with Article XIII.
