The Government is seeking to identify qualified sources either singularly or as part of an assembled team under North American Industry Classification System (NAICS) code 237990, Other Heavy and Civil Engineering Construction, which has a small business size standard of $36,500,000.00.Project Description: In accordance with FAR 36.204, and DFARS 236.204, the estimated construction price range for each project is between $100,000,000 and $250,000,000.00.

The estimated total contract performance period is 1096 calendar days. Location of this work is Camp Pendleton, San Diego County, CAThe original levee was constructed in response to the 1993 flood that caused disastrous damages to infrastructure, aircraft, support equipment and suspended crucial national security Marine Corps aviation operations. The existing SMR Levee system was constructed between 1998 to 2001 as an emergency response after the 1998 flood event.

Since construction completion of the levee system, maintenance of the levee and its appurtenances have been minimal. As a result, the waterside and some sections of the landside of the levee system exists with heavy vegetation and tree overgrowth that appears to impact the levee. The SMR levee system is approximately 3 miles long with 3 segments, i.e., West Segment, Air Station Segment, and East Segment, and two project features, i.e., Floodwall and the Pump Station.

The SMR levee system was constructed with 1:1 (Horizontal: Vertical) gradient embankment slopes comprised of either all soil-cement or a combination of geogrid reinforced earth and a soil cement shell on the riverside of the levee and crown. The Flood Wall project feature is a reinforced-concrete cantilevered retaining wall, approximately 21 feet high, and approximately 0.5 miles long.

At the riverside of the levee, a stone revetment was placed at the toe of the embankment and flood wall to protect against erosion and scour. At the landside of the embankment, a toe berm was constructed and a subdrain system was installed at the toe. The levee is owned, operated, and maintained by MCAS Camp Pendleton. Proposed anticipated repairs to the Santa Margarita River System include the following:

a) A levee raise to increase height about 2.5-4.5 feet vertical in the levee profile downstream of the Basilone Bridge and at the East Levee segment with soils Cement, this includes a stability berm approximately 3 feet vertical by 10 feet along at the east levee for about ~1100 feet long. A borrow site is identified about a mile away for soils cement use. It is anticipated that approximate 50K cubic yards of materials will be used for soil cement and general fill materials. An onsite soils cement batch plant will be required.

b) Installation of several relief wells on the Air Station Segment.

c) Replace and install a new toe drain and or abandoned existing toe drain along the interior of the levee system.

d) Construct a graded gravel filter ditch at the landside of the Air Station Segment and Floodwall.

e) Scour and erosion mitigation measures for armoring the riverside of the entire levee system with Launch Stone with approximate 36-inch diameter graded stone. The launch stone would vary with approximately 5-8 feet high located at the riverside of the levee.

f) The existing Floodwall Structural would be strengthened and improved by adding addition rebar and concrete.

g) Existing cracks will be filled in with a cement grout mix with an expandable sealant to prevent future cracks.

h) Project Maintenance Paths and Access. Several 10-12 feet wide maintenance paths and ramps will be constructed for access to the riverside and landside of the levee.

i) A 15-foot-wide vegetation clearance pathway would be required from the proposed project features.

j) Vegetation restoration within the temporary impact areas.

k) NEPA and Environmental Compliance.

l) Air Station Camp Pendleton Compliance and criteria. Prior Government contract work is not required for submitting a response to this sources sought notice.
