City Council Agenda Item Report
BACKGROUND:
On April 9, 2007, the City Council awarded a construction contract to DLSB, Inc. for
the Combined Sewer Improvement Project consisting of Eveward Road, Drakewood
Avenue, Whitburn Avenue, Flaxton Street, Blackwelder Street, Smiley Drive,
Northgate Street, Cranks Road, Commonwealth Alley, and Carson Street, Sewer
Improvement Projects, P-839, 840, 841, 842, 854, 855, 773, & 860 (Combined
Sewer Improvement Project).
The scope of work consists of the replacement of the existing 6”, 8”, 10”, and 12”
vitrified clay pipe (VCP) with new 8”, 10”, and 12” Polyvinyl Chloride (PVC) sewer
mains and the replacement of sewer laterals between the sewer main and curb line.
On September 24, 2007, the City Council awarded a construction contract to DLSB,
Inc. for the Alley Drain Improvement Project, (P-295) located south of Washington
Boulevard between Elenda Street and Midway Avenue. Project P-295 consisted of
constructing 600 linear feet of 12-inch Polyvinyl Chloride (PVC) storm drain mainline,
four (4) 24-inch by 24-inch catch basin inlets, and 590 linear feet of a 48-inch wide
longitudinal gutter. The new storm drain was connected directly to an existing 30-
inch Reinforced Concrete Pipe (RCP) storm drain mainline located on Elenda Street.

DLSB, Inc. completed the work required in the original contract with four change
orders. The total amount of the change orders was $377,240.80. The change
orders were for the extension of the sewer lateral from the curb face to the property
line and unforeseen conditions, such as concrete encased sewer main lines that
required removal, buried concrete along the sewer alignments, unmarked and
abandoned utilities and oil pipelines, and quantity adjustments that added to the
current construction cost and schedule.
During the course of construction it was observed by video tape inspection that most
of the sewer laterals along Carson Street, Northgate Street, Flaxton Street, and
Whitburn Street had extensive damage caused by street tree root intrusion that
resulted in significant blockage of the pipe diameter. Due to this extensive street
tree root intrusion in the sewer laterals, staff approved a change order to extend the
sewer lateral replacement to the property line instead of the curb line as originally
planned All the sewer laterals along Carson Street and thirty-seven (37) sewer
laterals along Northgate Street, Flaxton Street, and Whitburn Street were replaced
between the sewer main and the property line.
Property owners whose sewer laterals were observed to have extensive root
intrusion on their private properties were informed of the condition.
Alley Drain Improvement Project, P-295
The project for a new storm drain line in the alley between Elenda Street and
Midway Avenue was successfully completed by DLSB, Inc. Two change orders
were issued due to an unknown utility conflict and for an additional storm drain
lateral. The total amount of these changes orders is $6,100. The new storm drain
performed its function during the recent rains this winter.
