Marysville Ring Levee Repair Phase 2C

Marysville Ring Levee (MRL) Phase 2C Construction Project
The government anticipates issuing an Invitation for Bid (IFB) with the intent of
awarding one Firm-Fixed Price construction contract for the Marysville Ring
Levee Phase 2C Construction Project.
PROJECT DESCRIPTION
The Marysville Ring Levee (MRL) Phase 2C project is located in Yuba County
CA, on the right bank of the Yuba River, in the city of Marysville. The project
consists of degrading a section of the levee, constructing an approximately 90
foot deep cutoff wall using the Deep Mix Method, and reconstructing the
degraded levee section.
Construction must be completed within one construction season (15 Apr 2020
to 31 Oct 2020). The cutoff wall will be constructed at the center line of the
levee. One end of the wall is adjacent to an active railroad and the other end
is adjacent to State Highway 70. Approximately 6 to 8 feet of levee section
material will be degraded (approx. 13,500 Cubic Yards (CY) to provide a
platform for construction of the cutoff wall. The levee will be reconstruction
using levee embankment (fill material) (approx. 17,000 CY) and levee
embankment (clay cap) approximately (2,000 CY). An existing shallow cutoff
wall, which is approximately 350 feet long (Station 237+00 to Station 240+50)
will also need to be degraded to the construction platform and the new cutoff
wall will be constructed parallel to the existing wall.
The cutoff wall must be soil-cement-bentonite (SCB) constructed using in-situ
soil mixing methods classified as either: Wet Rotary Shaft (WRS), Wet Rotary
End (WRE), Wet Rotary and Jet End (WJE), or Wet Vertical Panel (WVP); as
described in the Federal Highway Administration Design Manual: Deep Mixing
For Embankment and Foundation Support. Methods that do not use
mechanical soil cutting or mixing are NOT acceptable. The cutoff wall minimum width is 2 feet and the cutoff wall length is approximately 1,100 feet.
The cutoff wall will require a demonstration section to be constructed and approved before construction of the production wall can begin. The cutoff wall
depth will vary up to 90 feet and the construction equipment must be capable
of constructing the cutoff wall 20 feet deeper than the maximum depth shown
on the drawings. The total square footage of the cutoff wall is approximately
91,000 ft^2.
The in-situ soil mixing must produce an incompressible, relatively lowstrength,
low- permeability, continuous seepage cutoff wall with an
appropriate overlap between elements and/or headings to ensure continuity to
full depth. The cutoff wall must consist of either a series of overlapping SCB
elements formed underground, through and beneath the levee, or by a fulldepth
horizontal advancement. The permeability must be less than 5 x 10^-7
centimeters per second (cm/sec) with the strength of the cutoff wall between
50 and 300 pounds per square inch (psi).
The total amount of excavation for the levee degrade is approximately 13,500
CY, 17,000 CY will be used as levee fill material, and 2,000 CY will be used
as clay cap. The embankment will be reconstructed and erosion control
measures must be provided in disturbed areas.
As a matter of contractor responsibility per FAR 9.104-1, the apparent low
bidder will be required to provide evidence demonstrating that it possesses
experience in performing in-situ soil mixed cutoff wall construction projects
within the last 10 years (i.e., since July 2009). The qualifying experience must
consist of successful completion of a MINIMUM two soil-cement or soilcement-
bentonite cutoff wall projects using an in-situ soil mixing method as
described above. The cutoff wall projects must have a minimum depth of 70
feet and a minimum area of 100,000 ft2, with a minimum width of 36 inches.
The cutoff wall properties must have a maximum permeability of 1 x 10^-6
cm/sec. Multiple headings on one contract are considered as one construction
project and project experience claimed must have been performed by the
entity that will perform the work of this solicitation.
In submitting a bid, the contractor is asserting a promise to perform the
contract requirement as described by the plans, specifications, terms and
conditions contained in the solicitation. Additionally, the contractor is asserting
they will comply with the following requirements for the following key
personnel:
The Soil Mixing Equipment Operator(s) must have experience in using similar
equipment to be used for this solicitation in a minimum of two successfully
completed projects and a minimum of five years of experience similar to the
projects described in paragraph Contractor above. The projects listed in the
resume must be similar to the requirement described in this presolicitation
notice in the following three ways: comparable scope, complexity and physical
size completed; and
The Soil-Mixed Cutoff Wall Specialist(s) must be experienced in providing
supervision of mix design and field control composition and mixing of the soilcement
or soil-cement bentonite using in situ soil mixing equipment. The
projects listed in the resume must include a minimum of two successfully
completed projects and a minimum of five years of experience on projects
similar in scope, project type, physical size and complexity to this solicitation
and meeting the project criteria in paragraph Contractor above. The
experience must include to the following four criteria: (1) controlling
composition, mixing, placing, sampling, testing and maintaining
bentonite/cement slurry; (2) supervision of alignment, verticality, and depth of
soil mixing equipment; (3) controlling blending, mixing, sampling, and testing
in-situ material; and (4) a thorough knowledge of soil mixing and cutoff wall
construction equipment and material testing.
ADDITIONAL INFORMATION
- As stated in paragraph one of the Project Description above, the contractor
must finish within one construction season (15 Apr 2020 to 31 Oct 2020).
There are two active construction projects in the same vicinity and will need
coordination on all construction schedules and overlaps.
- Marysville Project is seeking the following specialized expertise for the 2C
Construction Contract for award by approximately 30 September 2019.
- Levee is within Union Pacific Railroad (UPRR) right-of-way and will require
contractors and employee to take UPRR training.
- Biz Johnson road will be closed during construction but contractor will still be
required to provide flaggers for Bridge Contractor (5th Street Bridge) to
enter/exit project for equipment.
In accordance with FAR 36.204(g), the estimated value of the resulting
contract is expected to be between $5,000,000 and $10,000,000.
The IFB is estimated to be issued in July of 2019 with bids due approximately
30 calendar days later. The IFB will be issued on FBO.gov.
The site visit date and location will be identified in the solicitation.
