INTEROFFICE MEMO
DATE: OCTOBER 17,2018
TO: JESUS CHAPA,ASSISTANT CITY MANAGER I
DOUG BLACK,SR.ASSISTANT CITY ATTORNEY io��I rfg
FROM: CHRIS HARDER,WATER DIRECTOR
SUBJECT: TRINITY RIVER STREAMBANK EROSION AFFECTING TWO 90"
SANITARY SEWER LINES—EMERGENCY RESPONSE
Two 90"diameter sanitary sewer lines (West Fork sewer'lines) were installed in the 1960's and
1970's that initially connected the old Riverside Plant with the Village Creek Plant, They are
generally aligned parallel to and offset from the Trinity River. These two pipelines currently
convey the majority of the wastewater generated in Fort Worth to the Village Creek Plant, with
flow capacity of upwards of 200 million gallons per day.
In the spring of 2016,Trinity River streambank erosion was discovered that threatened to expose
and potentially undermine the West Fork sewer lines. An emergency contract was authorized in
June of 2016 (CS No. 47913, see also,June 7, 2016 Emergency Memo) for the installation of
two sheet pile cutoff walls, a temporary solution designed to help protect the pipelines while a
permanent solution was designed and permitted by the U.S: Army Corps of Engineers. The
emergency work was completed in July 2016.
The City engaged James Deotte Engineering,Inc. (M&C C-27950)to develop,design and permit
a permanent solution to the erosion problem. The approved design is to install a reinforced
concrete wall supported by drilled shaft piers that would act as the foundation for a rock gabion
basket reinforced channel slope. The drilled piers would be extended into bedrock to provide
permanent stability. The rock gabion basket would be extended from the concrete foundation up
the channel bank side slope to prevent erosion.
The Corps of Engineers permit for this permanent solution was obtained in the summer of 2017.
Bids for the construction of the permanent solution were obtained in late July of that year and on
September 26, 2017 (M&C C-28407) council authorized execution of a construction contract
with Humphrey and Morton in the amount of$1,867,535 to construct the permanent solution.
Construction of the drilled piers was delayed almost a year, however, in part due to final
easement acquisition and the discovery of artifacts in the work zone that required mitigation.
Once the drilled.pier construction began in late summer of 2018,it was discovered that the rock
layer encountered at several locations was deeper than what was logged in the geotechnical bores
taken as part of the design.Unfortunately,the engineering design needed to be revised to provide
additional depth to the drilled piers to strengthen the foundation and additional vertical tie-back
reinforcing of the proposed protective wall. That redesign has just recently been completed and
provided to the contractor for a cost assessment.
On September 22,2018,Fort Worth was hit by a severe storm which eroded significant portions
of the Trinity River and resulted in the failure of one of the sheet.pile cutoff walls. The second
ti cutoff wall is now unstable and needs to be reinforced immediately (see attached pictures). On
October 13, 2018, another storm increased the Trinity River water surface elevation at least 13'
in*the impacted area,resulting in additional erosion of the streambank. Rain has occurred every
day from October 131h up to the date of this memo and significant rain is forecast for the next
several weeks.
With the construction of the permanent solution gabion wall project expected to take six months,
preparation and placement of materials and equipment necessary to perform bypass pumping
should the transmission pipes be compromised is necessary to protect public health.
Under this emergency memorandum the Water Department intends to do the following:
1. Reinforce and repair the existing sheet pile cutoff walls and prevent further failure
(installation of driven piles with tieback rods to support). It is anticipated work will be
performed by Shin and Gregory and Circle C Construction, the construction team that
performed the original emergency work,at an estimated cost of$200,000.
2. Expose the West Fork sewer lines at points upstream and downstream of the
compromised area in order to allow expedited bypass pumping. It is anticipated this
work will be performed by Circle C Construction at an estimated cost of$50,000.
3. Install approximately 3,000 linear feet of 24" HDPE piping, to be in place should
emergency bypass pumping be required.Work is anticipated to be performed by Circle C
Construction. Estimated cost of$250,000.
4. Purchase two 40"sewer plugs and position them at the site for the duration of the project.
These plugs will be' needed in the event of damage to the existing pipes that requires
bypass pumping. It is anticipated that these plugs will be purchased from Sunbelt Rentals
at a cost of approximately$60,000.
5. Rent bypass pumps and pump manifold. Costs vary based on duration of rental. Should
the rental last several months, total cost would be approximately $300,000. It is
anticipated that Sunbelt Rentals will be utilized for pump and manifold rentals.
6. Execute an emergency contract with Humphrey and Morton to immediately proceed with
installation of vertical-tiebacks and extra depth piers as required by the revised rock ledge
information described above. Estimated cost for this additional work is$650,000
Waiting to prepare a change order to the contract under which the permanent solution is being
constructed for the'additional piers and tie-back structures is not prudent givers the saturated
conditions and forecast for more heavy rain. The City is exempt from competitive bidding when
an emergency threatens the preservation of the city's property or the public health of the citizens.
Concurrently awarding emergency contracts to repair the failing cutoff walls and establish
procedures for bypass pumping, should there be a failure of the pipeline, furthers the interest of
protecting the public health and safety of the City as well as being necessary to protect the city's
property. Chapter 2, Article I, Section 2-9 at (9) of the City's Code of Ordinances and Section
252.022 of the Local Government Code exempts from normal bidding requirements expenditures
that are necessary to preserve or protect the city's property and the public health or safety of the
municipality's residents.
This memo is submitted to request authorization for emergency procurement of services outlined
above, at a total cost of approximately $1,510,000. While this cost is extremely high, the
consequences of one or both of the 90"pipes failing and allowing raw wastewater to flow into
the Trinity River are dire and this must be prevented.
A confirming M&C will be circulated to ratify the above activities after the work has been
performed.

INTEROFFICE MEMO I
DATE: APRIL 25,2019
TO: JESUS CHAPA,ASSISTANT CITY MANAGER
DOUG BLACK, SR.ASSISTANT CITY ATTORNEY
FROM: CHRIS HARDER,WATER DIRECTOR
SUBJECT: EMERGENCY REPAIRS—UPPER CLEAR FORK SEWER LINE(M-
439*)
On April 24th, Water Field Operations was called to investigate a 5 ft. diameter sinkhole,
approximately 8 ft. deep, located south of the W. 7a' St./Harrold St. intersection, in Trinity Park.
The sinkhole is located over the existing 36-inch siphon on M-439* which crosses under the
existing 72-inch raw water main to North Holly Water Treatment Plant.
It is estimated that up to 40 LF of the existing 36-inch ductile iron pipe will be replaced with new
36-inch ductile iron pipe as part of the emergency response. Bypass pumping of the wastewater
flow shall be performed in order to replace the existing pipe.
The repair locations are shown in detail on the attached plans.
It is beyond the capacity of Water Department staff to perform repairs of this size and length.
Therefore, the Water Department has contracted Conatser Construction TX, L.P. to perform the
pipe replacement and related bypass pumping.
Waiting to bid and award a-.ontract to replace the damaged sewer line is not in the best interest
of the health and safety of the citizens of the City of Fort Worth. Chapter 2,Article I, Section 2-9
of the (ity's Code of Ordinances and Section 252.022 of the Local Government Code exempt
from normal bidding requirements expenditures that are necessary to preserve or protect public
health or safety of the rmut cipxliiy's residents; and procurements necessary because of
unforeseen damage to public machinery,equipment, ui t rupeily.
This memo is submitted to request authorization for emergency procur:,ment of :orstruction
services provided by Conatser Construction TX, L.P.. The total cost associated with this
emergency is estimated to be$400,000.
An M&C will be circulated to ratify the emergency contract after the work has been performed.

RE: SUPPLEMENT TO APRIL 25,2019 MEMORANDUM AND CITY SECRETARY
CONTRACT NO. 52264 RE: EMERGENCY REPAIRS—UPPER CLEAR FORK
SEWER M-439*
This memorandum is to supplement the April 25, 2019 emergency memorandum — resulting in City
Secretary Contract No. 52264 with Conatser Construction TX,LP("Conatser")for emergency services to
reroute the cracked leaking segment of sewer main M-238 from an inaccessible location at the bottom of a
tributary creek of the Trinity River to a location further away from the creek edge. The existing alignment
of the 30-inch main at the edge of the creek has been continuously eroded over the years and is now exposed
which possibly caused a hole to form in the pipe.
To expedite the reroute, staff recommends that City Secretary Contract No. 52264 be revised to allow
Conatser to do the work.It is anticipated that the additional work may cost up to$700,000.00
A change order will be processed to the existing contract with Conatser and actual costs will be reconciled
at the end of the project. y

Mayor and Council Communication
DATE: 09/24/19 MSC FILE NUMBER: M&C 19-0212
LOG NAME: 60EMER52264&51521 FUNDING
SUBJECT
Adopt Appropriation Ordinance in the Amount of$1,442,119.00 for Increased Project Costs for the Emergency Sewer Work Performed in Trinity
Park,at a Tributary Creek of the Trinity River and Trinity River Stream Bank Erosion Affecting Two 90-inch Sanitary Sewer Mains(COUNCIL
DISTRICTS 4,5 and 9)
RECOMMENDATION:
It is recommended that the City Council adopt the attached appropriation ordinance increasing estimated receipts and appropriations in the Water
and Sewer Capital Projects Fund in the amount of$1,442,119.00 from available funds for the purpose of funding emergency sewer work
performed in Trinity Park and at a tributary creek of the Trinity River for$442,119.00 and Trinity River Stream Bank erosion affecting two 90-inch
sanitary sewer mains for$1,000,000.00(City Project Nos. 102295 and 102346).
DISCUSSION:
Funding is necessary for the following emergency sewer work that was conducted by two contractors at three locations in the City.
Trinily Park and Tributary Creek Work.Conatser Construction TX,LP was engaged under an emergency memorandum for the replacement of a
40-foot collapsed segment of Main 439 in Trinity Park and,subsequently,the reroute of a segment of cracked Main 208 from its inaccessible
location at the bottom of a tributary creek of the Trinity River to a location further away from the creek edge near 9065 John T.White Road.The
attached City Manager memo dated April 25,2019 creating City Secretary Contract No.52264,and supplemental Memorandum dated June 20,
2019,approved the emergency work collectively up to$1,100,000.00.The amount invoiced to date is$367,118.65 with an anticipated remaining
cost of$75,000.00 to finalize the repair(CPN 102295).
Trinity River Bank Erosion Work. In the Spring of 2016,significant erosion to the Trinity River bank began to place the two 90"sanitary sewer
mains running parallel and adjacent to the river which convey nearly all of the sewer system's flow to Village Creek Wastewater Treatment Facility
in jeopardy.An emergency construction contract was issued and temporary sheet pile cutoff walls were installed to protect the mains while a
permanent solution was designed.The permanent solution consisting of permanent bank stabilization was designed,permitted and competitively
procured in 2017 and was under construction by the contractor,Humphrey and Morton Construction Company, Inc.("HMCCI")when the heavy rains
of Fall 2018 caused additional erosion of the stream bank and further jeopardized the integrity of the sewer mains. HMCCI was engaged under an
emergency memorandum and contract to construct additional,enhanced,shoring improvements along the Trinity River streambank(vertical
tiebacks and extra depth piers)to protect the mains.See the attached City Manager memo dated October 17,2018 and City Secretary Contract
No.51521. However,due to additional significant erosion of the riverbank caused by heavy rainfall in Spring of 2019, HMCCI has not been able to
safely access the project site to install the designed slope stabilization to permanently protect the two sewer mains.Alternative construction
options are being evaluated and it is expected that there will be additional construction costs,estimated at$350,000,needed under the original
$650,000 emergency authority. (CPN 102346)
This action will have no effect on the Water Department's operating budget when complete.
The project is located in COUNCIL DISTRICTS 4,5 and 9.
A Form 1295 is not required because: This M&C does not request approval of a contract with a business entity.
FISCAL INFORMATION/CERTIFICATION:
The Director of Finance certifies that upon approval of the above recommendation and adoption of the attached appropriation ordinance,funds will
be available in the FY2019 capital budget,as appropriated,of the Water and Sewer Capital Projects Fund.The Fiscal Year 2019 Water Operating
Budget includes appropriations of$35,856,873.00 for the purpose of providing Pay-As-You-Go funding for Sewer Capital Projects.After this
transfer for Fiscal Year 2019,the balance will be$6,600,616.00.Prior to any expenditure being incurred,the Water and Sewer Department has the
responsibility to validate the availability of funds.
