Re: Cefe F. Valenzuela Landfill Compost Facility (MSW-2269) Design, Bidding and
Construction Services. Project 20288, Phase II, Amendment 2
Dear Ms. Weinberger:
Thank you for the opportunity to provide professional engineering services for the City of Corpus
Christi (City) Compost Facility (Compost Facility)
waste landfill (Landfill). The following outlines
proposal to complete this work, which will include design, bidding and construction phase services
(Phase II).
The proposed Compost Facility is approximately 106 acres in size and will be located on the
eastern portion of the Landfill permit boundary, north of the future disposal Unit 2. The Compost
Facility will include the following operation areas:
Lined active composting area
Screening, curing and final product area
Future bagging plant area
Feedstock storage area
Mixing/blending area
Crushing pad
Roadways and parking area, including covered storage for equipment
Fueling station (diesel storage tank)
Lined stormwater retention pond
This project will include lighting along with the necessary power requirements for the fueling
station and a pump associated with the crushing pad. Hanson will employ a sub-consultant (Bath
Group, Inc., Corpus Christi) for the electrical engineering design of these features.
Our staff is thoroughly familiar with the Landfill and
and construction procurement process. Based on this understanding of the work, we propose to
perform the following specific tasks:
Engineering Design and Assistance with Bidding
Engineering Letter Report (ELR)/30%
The ELR will be based upon the facility configuration as depicted in the Compost Facility
permit modification, previously prepared by Risa Weinberger & Associates, Inc. and Hanson,
Ms. Risa Weinberger, P.E.
Risa Weinberger & Associations, Inc.
January 16, 2024

and approved by TCEQ on September 1, 2023. The following is a brief description of each of
the operation areas.
The lined active composting area will include a 2-foot re-compacted clay liner with a
windrow operating
surface. It is anticipated that both the clay and protective cover soil will be available
on-site. The permitted site layout designates approximately 40 acres for the lined
composting area. Hanson will provide a design for the entire area, but it is our
understanding that the City is only planning to construct 25 acres in the initial
development, therefore the construction plans will reflect that configuration.
The screening, curing and final product area will be constructed with an operating
with a footprint of approximately 16 acres.
The future bagging plant area will consist of a footprint of approximately 2.25 acres,
be graded for future use, but otherwise left undeveloped.
The feedstock storage area will be graded and constructed with an operating surface
of compacted on-site soil with a footprint of approximately 9.4 acres.
The mixing and blending area will be graded and constructed with an operating
surface of compacted on-site soil with a footprint of approximately 0.75 acres.
The crushing pad will be a sloped concrete surface for crushing certain feedstocks to
release liquids that will flow to a trench drain where it will be collected in a buried
storage tank. The crushing pad will have a footprint of approximately 21,000 square
feet (s.f.). The storage tank will have an approximate capacity of 500 gallons. Liquid
from the tank can be pumped into transport equipment and applied to the windrowed
materials as needed.
Roadways and parking areas will be surfaced with flexible base material. The parking
area will also include approximately 40,000 s.f. of exposed surface and a 4000 s.f.
covered storage area for heavy equipment. The cover for the storage area will be
framed with structural steel, founded on concrete column footings, with steel sheet
metal roofing and will be unenclosed. There will be a brick entrance to the facility
entrance will have a rolling aluminum gate for access control, similar in design to the
existing operations area entrance.
The design will include an un-covered a fueling station with an above-ground double-
walled diesel tank. The fueling area will include a drip pad for containment of
incidental operational spills and will include pumping equipment for high-volume
diesel fuel delivery.
Stormwater runoff from the active composting area will be collected via surface sheet
flow across an existing pipeline easement to geomembrane-lined drainage channels
and then directed to a geomembrane-lined stormwater retention pond. The drainage
channels will consist of approximately 2,500 linear feet and the stormwater retention
pond will have a footprint of approximately 6 acres.
The design will include limited area lighting focusing on security (rather than
operations) for the covered heavy equipment storage structure, the fueling station
and the parking area.
No building structures other than the heavy equipment storage shed will be included. It is also
assumed that the City will be responsible for the extension of power to the composting facility

by Nueces Electric Co-op (NEC). If requested, Hanson can provide assistance in the form of
NEC easement preparation and surveying through an MSA task order.
Hanson will prepare the ELR/30% design submittal and host a design workshop with the City
to review the package. The package will include:
A plan view layout of the proposed construction, including the proposed compost facility
configuration as well as the components that will be a part of the project.
A technical memo outlining construction work items for the bid package, approximate
quantities and preliminary opinion of probable construction costs, and a description of
additional requirements (e.g., TCEQ mandated construction inspection/quality assurance
testing, regulatory submittals)
A proposed project schedule.
60% Construction Documents Package
Based on the comments received from the City on the ELR/30%, Hanson will prepare draft
construction documents representing approximately 60% design completion and will meet
with the City in a design review workshop. The package will include:
Construction drawings, including plans, sections, and details, for the construction
components identified in the ELR. Drawings will include the record drawing number as
provided by the City.
Construction specifications for construction components identified in the schematic
design.
Contract documents, including instructions to bidders, agreements, bonds, general
conditions and special conditions, using City standard forms with information required to
render those forms suitable for the project.

be archived from AutoCAD Civil 3D as Adobe Acrobat Portable Document Format (.pdf) set
up as
Contract documents and specifications will
be prepared in Microsoft Word and will be archived as .pdf.
90% Construction Documents Package
Based on the comments received from the City on the 60% Construction Documents Package,
Hanson will prepare a 90% design submittal package of construction documents and will meet
with the City in a design review workshop to review the package. The package will include
updated versions of the documents furnished for the 60% submittal along with an opinion of
probable construction cost.

Support Services
Pre-Construction Topographic Surveying
Hanson will perform a limited pre-construction topographic survey of the proposed Compost
Facility construction area to obtain information on existing conditions necessary for design,
including estimation of excavation and/or fill volumes. This will include the area where the
lined retention pond will be located. This survey will be performed using conventional
surveying equipment, based on the survey datum provided in the TCEQ permit documents.
There will be no separate deliverable of the pre-construction topographic survey; the results
will be incorporated into the design and construction documents.

purpose of checking for general conformance with the design concept expressed in the
contract documents. Hanson shall not be responsible for any deviations between the
shop drawings, the contract documents, and field conditions.
Provide interpretations and clarifications of the plans and specifications for the contractor
the construction contract and are not contrary to the general interest of the City under
the contract.
Review and evaluate up to three (3) change order proposals that may be necessary
during the progress of the work including a recommendation to accept or reject.
Consult with the City and exchange oral status reports on a weekly basis during
construction.
Make weekly visits to the project site to observe the general progress and quality of the
work, and determine, in general, if the work is being done in accordance with the
contract documents and in accordance with the quantities of work represented in current
contractor requests for payment. The site visits will include a duration of up to four (4)
hours per week and will be conducted through the six (6) month construction schedule.
Weekly site visits will not constitute or be confused with resident project representative
services or continuous monitoring of the progress of construction. Hanson sub-
consultants may also make up to three (3) site visits during construction. Additional on-
site observation will be provided by our subcontractor, Modern Technology/Modern
Environment (MTME) of Corpus Christi, Texas as a portion of the Geotechnical Quality
Assurance (QA) services as described below.
Conduct an inspection in anticipation of substantial completion and prepare a punch list
of items for correction, repair or installation by the contractor prior to final inspection.
Conduct a final inspection with the City and contractor, to include an orientation by the
contractor to familiarize City personnel with the mechanical and control systems.
-, field observations,
approved change orders, and documented changes reported by the City inspector(s),
Hanson will prepare a set of record drawings to be provided in both electronic format (as
described for the 60% submittal) and in one (1) hard copy.
Post-Construction Topographic Surveying
Hanson will perform post-construction topographic surveys to document the horizontal and
vertical placement of construction elements required by TCEQ regulations,
and the construction QA documents. These will include surveys of the subgrade, the
compacted clay liner, protective cover layer over the liner, and the geomembrane liner panel
seams at the retention pond. We will also coordinate to confirm
existing survey control system. This proposal is
based on no more than two (2) separate mobilizations of one (1) day each to complete these
post-construction topographic surveys.
Geotechnical QA Services (SLER & GLER)
TCEQ regulations and the facility permit require that during the liner construction, the City
provides geotechnical QA services to confirm that the composting area liner materials (clay
and protective soil) meet the required material properties and that the construction and
installation procedures comply with the requirements identified in the permit and QA
documents. Additionally, it is required that a qualified technician or engineer be present on
site at all times when clay liner construction or pond and ditch liner installation is occurring.
This on-site observation will be supplemented with the field and laboratory testing program
Ms. Risa Weinberger, P.E.
Risa Weinberger & Associations, Inc.
January 16, 2024

outlined in the permit and QA documents. Properly credentialed personnel and analytical
laboratories will be used for all testing, as outlined in the permit and the QA documents. The
results of all field and laboratory testing will be included in the appropriate reports submitted
to the TCEQ.
MTME will provide construction Quality Assurance (QA) services and preparation of the
documentation for TCEQ submittal. MTME staff will be on site to observe and document
construction, as well as coordinate sampling and field and laboratory testing of construction
materials. As the professional of record, MTME will prepare the Soil Liner Evaluation Report
(SLER), and the Geomembrane Liner Evaluation Report (GLER) for submittal to TCEQ.
Because the QA effort is greatly influenced by the schedule and productivity of the contractor,
the fee for geotechnical QA services is recognized as an estimate and billing will be on a time
and materials (T&M) basis for actual hours worked plus reimbursable costs (materials testing,
shipping, vehicle and equipment usage, etc.). The fee estimate for the QA services is based
on a construction contract term of six (6) months from Notice to Proceed to substantial
completion, working twelve (12) hours per day, seven (7) days per week.
