4 THIS AGREEMENT is made by and between The City of Fort Worth, a Texas home rule municipality acting by
5 and through its duly authorized City Manager, ("City"), and HUMPHREY & MORTON CONSTRUCTION
6 COMPANY, INC., a corporation authorized to do business in Texas, acting by and through its duly authorized
7 representative ("Contractor'). City and Contractor, in consideration of the mutual covenants hereinafter set forth,
8 agree as follows:
9 Article 1.WORK
10 Contractor shall install vertical tiebacks and extra depth piers that would act as the foundation for a rock gabion
11 basket reinforced channel slope.
12 Article 2.PROJECT
13 The recent ranis of September and October 2018, have further eroded the bank of a portion of the Trinity River
14 compromising the integrity of the City's twin 90-inch sanitary sewer mains (M-280-13and M-338-B)which covey
15 sewage to the Village Creek Treatment Plant. The lines must be protected.
16 In the spring of 2016 two temporary sheet pile cutoff walls were installed to protect the mains while a permanent
17 solution was designed. The permanent solution was under construction until the recent rains destabilized the
18 temporary solution causing further erosion of the stream bank.
19 Article 3. CONTRACT TIME
20 3.1 Time is of the essence.
21 Contractor recognizes that time is of the essence, and the Contractor will be required to remain on the jobsite until
22 the work on repairing the cut off walls and procedures for bypass pumping is completed. The City expects the
23 Contractor to have a sense of urgency to complete the Work in a timely manner.
24 Article 4. CONTRACT PRICE
25 City agrees to pay Contractor for performance of the Work based on Contractor's invoice an amount up to Six
26 Hundred and Fifty Thousand Dollars ($650,000.00) This figure may be amended up or down as final invoices are
27 received.

INTEROFFICE MEMO
HATE: OCTOBER 17, 2018
TO: JESUS CHAPA, ASSISTANT CITY MANAGER
DOUG BLACK, SR. ASSISTANT CITY ATTORNEY 4
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 wlule 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
cutoff wall is now unstable and needs to be reinforced immediately (see attached pictures). On
October 13, 201 S, 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 13'x' 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 90'' 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 given 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.
