Re: Resaca LS & 48" Gravity line and Antelope Street and Salt Flats Are~ 36"/48"
WW Gravity Interceptor Projects
City Project # 7288/7302
Man-hours/Cast Breakdown for Additional Services
With this letter, Maverick Engineering, lnc is requesting for additional engineering fees for the
above mentioned projects.
Maverick Engineering, Inc. (MEI) was contracted to provide engineering services for design of
36"/48" gravity line and lift station, Project No. 7288 in April 2003. MEI was to prepare plans
and specifications for the said project and have the project bid and constructed in timely
manners. Midway thru the design phase, the City requested MEI to complete the design of the
lift station and bid it separately from the gravity sewer line. MEI complied and expeditiously
completed plans and specifications for the lift station, a portion of 48' gravity line and a new
mechanical bar screen. This was done within a period of two months and the project was bid
successfully within the budget. This requested package required that we worked long hours
which included a huge overtime effort and as such we exceeded our allocated fees for the
project design
Even though we had fast tracked the design of the lift station, additional man-hour efforts had
to be allocated once the Resaca LS was advertised for bid. At the City's request, a mechanical
bar screen and the security system were added to the project during the bid phase of the
project. Initially, during the Preliminary Phase, after several meetings with the City, it was
decided that the bar screen was not required on influent line to the lift station because of the
size of pumps and would be included as part of future plant design. During the bid phase, it
was decided that the mechanical bar screen would be required for the interim phase as the trash
would choke up mechanical equipment in the treatment plant if no screening was provided. As
such, the mechanical bar screen and trash conveyor/compactor were sized and designed along
with the concrete structure within two weeks and the design was completed in time to he

included as part of the bid proposal. Also, during the Preliminary Phase, all the estimates were
submitted for dual power source with two independent power lines to the lift station. Midway
through the Design Phase this was changed to a standby generator instead of providing a
second power line. Additional time was devoted to upgrade the building and redesign the
electrical system. Again, during the construction phase, a request was made to provide for
second power source as staff felt that a standby generator did not provide for enough backup
but after several meetings with the staff it was agreed upon to provide conduits and junction
box for a future power source.
Also, as part of the lift station design, a mechanized gate system with scan card reader
mechanism was added during the bid phase.
Moreover, by splitting the project into two projects, additional time was required for preparing
construction documents twice. Even though, this project was combined with Antelope St.
gravity line project, the engineering fee for the combined project of this magnitude was not
sufficient to cover the cost of designing the project and putting together the bid package. Given
below is a table showing the project construction cost estimates with allocated engineering
fees.

* Engineer's construction cost estimate
** Engineering Fees for 24" 0 Antelope St. Project.
It is important to note that initially, MEI was to provide inspection services for the project.
Keeping this in mind, the hours allocated for periodic visits by the engineer to the project site
were minimal. With this amendment, MEI is requesting additional fees to cover the following:
The costs to incorporate the mechanical bar screen
The costs to incorporate the changes related to the dual power especially the
redesign of the building.
The costs to incorporate the security system and mechanize the gate operation.
The cost to develop two design packages in lieu of one design package.
The costs to inspection services for both projects as the overall construction
time frame has almost doubled.

Additional engineering fee is also requested for the design of shoring as per Union Pacific
Railroad requirements for installation of 60' casing under the railroad at Sam Rankin and
Broadway Blvd. and allocating time for TxDOT permits.
With this letter we are requesting for an additional fee of $ 67,608.00. We have included a
detailed man-hours breakdown for your use/review.
