CITY COUNCIL REPORT
TO: Mayor and Members of the City Council
FROM: Lloyd V. Harrell, City Manager
SUBJECT: PURCHASE ORDF.1{ #559.99 - BOYD EXCAVATION
RECOMMENDATION: We recommend this purchase order be approved in the revised
amount of $124,650.00 for an increase of $79,150.00.
S~RY: This revised purchase order is for additional concrete rubble removai
over a collapsed 24" sanitary sewer line along Hickory Creek near Highway 377.
Council approved the expenditure amount of $45,500.00 on this rubble removal
project on June 20, 1995. At that time we were unaware of additional failed pipe that
would have to be replaced creating the requirement for additional rubble removal.
Also, as we moved down the pipe line the rubble depth increased from approximately
5 ft. to 24 ft. over the top of the line increasing the amount to be removed and the
amount of slope on the embankment required for safe access.
BACKGROUND: Purchase Order #55299 to Boyd Excavation, Memorandum to Council
dated June 20, 1995, Memorandum to Council dated July 26, 1995.
PROGRAMS, DEPARTMENTS OR GROUPS AFFECTF. D: Waste Water Field Services,
Citizens in the affected area, TNRCC and E.P.A.
FISCAL IMPACT: Funds will be paid from current Budget Revenue Funds. Part
of the funding for the Egan, Congress, and Panhandle CIP project will be pushed
into next fiscal year to compensate for the additional expenditure. The sliding of
this project enable the City to avoid using bond funds to finance the repair.

AGENDA ITEM
TO: MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: Lloyd V. Harrell, City Manager
DATE: June 20, 1995
SUBJECT: CONSIDER EMERGENCY PURCHASES FOR THE HICKORY CREEK 24"
SANITARY SEWER REPAIR
SUMMARY:
On May 24, 1995, a sanitary sewer was discovered running into
Hickory Creek near Highway 377. 150 to 200 gallons per minute
was discharged due to the collapse of a 24 inch sanitary sewer
line. The estimated costs to repair the collapsed line is as
follows:
· Excavation $56,000
· Material Purchase 13,463
· Bypass Pumping 6,537
$76,000
BACKGROUND:
On May 24, 1995, sanitary sewer was discovered running into
Hickory Creek near Highway 370. The 150 to 200 gallon per
minute discharge was due to the collapsing of the 24" sanitary
sewer line. The discharge was discovered due to
investigations of odor complaints in the area. The property
owner, Texas Natural Resource Conservation Commission and EPA
Region 6 were immediately notified upon discovery. Work began
to implement bypass pumping from the upstream manhole 883 feet
to the downstream manhole. The bypass pumping operation was
in place and running two days after discovery. The bypass
pumps must be watched 24 hours a day. The Wastewater Field
Services Division has set up 12 hour shifts to accomplish this
task.
Boyd Excavation was hired to look for the collapsed area on
Friday, May 26, 1995. On Monday, May 29, 1995, it was
discovered that only a small section had collapsed, but almost
378 feet of the pipe was damaged. A point repair could not be
made. 378 feet of the pipe would have to be replaced and a
new manhole installed.
Boyd Excavation has been working to prepare the site for
replacement. The estimated cost for excavation is $45,500.
To date $32,427 has been paid.
Once the site has been prepared, Jagoe Public will replace the
existing line. The City will supply materials. The estimated
cost is $13,463 for materials and $10,500 for the
installation. Installation of the replacement should begin on
June 14, 1995, and be completed by June 23, 1995.
PROGRAMS, DEPARTMENTS OR GROUPS AFFECTED:
The Citizens of Denton, Denton Municipal Utilities, TNRCC, EPA
Region 6, Boyd Excavation, Jagoe Public, BARCO, Rohan, and
Plank.
FISCAL IMPACT:
The total estimated repair cost should be approximately
$76,000. The money will be taken from current revenue. Part
of the funding for the Egan, Congress and Panhandle CIP
project will be pushed into the next fiscal year to compensate
for the extra expenditures. The sliding of this project
enables the City to avoid using bond funds to finance the
repair. (See Exhibit I for detailed expense report.)

TO: MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: Lloyd V. Harrell, City Manager
DATE: July 26, 1995
SUBJECT: CONSIDER EMERGENCY PURCHASES FOR THE HICKORY CREEK 24"
SANITARY SEWER REPAIR
SUMMARY:
This item was brought to the City Council on June 20, 1995
(See Exhibit I). At that time, the estimated cost to have
Boyd Excavation prepare this site was $45,000. The final cost
was $124,650. The estimated cost to have Jagoe Public replace
the line was $10,500. The final cost was $16,450.
BACKGROUND:
This item was originally approved by the City Council on June
20, 1995. The cost has increased since that time. The cost
for excavation increased due to the following reasons:
1. The concrete rubble was a lot harder to excavate
than expected.
2. It was necessary to slope the embankment more than
expected.
3. More line had to be replaced requiring more
excavation.
The cost to replace the line increased as well. The original
Purchase Order was for 300 feet. At the time, we took this to City
Council on June 20, 1995, is was expected that 378 feet would need
to be replaced. In fact, 470 feet was replaced.
PROGRAMS, DEPARTMENTS OR GROUPS AFFECTED:
The Citizens of Denton, Denton Municipal Utilities, TNRCC, EPA
Region 6, Boyd Excavation and Jagoe Public.
FISCAL IMPACT=
The $141,100 for these two items will be paid from current
revenue. Part of the funding for the Egan, Congress and
Panhandle CIP project will be pushed into the next fiscal year
to compensate for the extra expenditures. The sliding of this
project enables the City to avoid using bond funds to finance
the repair.
