Site work for a water / sewer project in Sacramento, California. Working plans call for site work for a water / sewer project.

This is the ANNUAL ON-RAMPING for the PREQUALIFICATION OF SOURCES LIST (PSL) announcement (previous notice W9123820S0001, W9123820S0022 & W9123821S0021), issued in accordance with DFARS 236.272 and the U.S. Army Corps of Engineers Acquisition Instruction (UAI) 5136.272. No reimbursement will be made for any costs associated with providing information in response to this announcement or any follow up information requests. Respondents will be notified of the results of the Prequalification of Sources Selection. If you are already pre-qualified for the features above you wish to perform, kindly confirm your continued interest. Please note in this PSL you may submit DMM qualifications however DMM is not included in the 95% submittal for contract 4. The U.S. Army Corps of Engineers (USACE), Sacramento District is seeking to expand the PSL for levee improvement cutoff wall construction within the Sacramento Valley. The objective of the Prequalification of Sources process is to identify and select responding firms that demonstrate the capacity and capability to successfully support critical USACE cutoff wall construction projects and thus establish a PSL. Identifying and selecting prequalified sources will be based solely on the responding firm's ability to meet the specific criteria that assess the firm's bonding capability, capability to concurrently complete large construction projects, previous experience completing a large cutoff wall construction project, financial accounting capabilities to support potential Government fixed-price contracts, and past performance. The selection process will be objective in that responding firms either meet or fail to meet the criteria. Failure to meet any one of the criteria may result in nonselection. The criteria were designed to ensure selection of clearly qualified contractors with experience and capability relevant to the anticipated requirements, provide competition, and minimize subjectivity in the Government's assessment. The PSL will be available for use while other acquisitions are underway for similar requirements. The PSL will be reviewed annually to ensure a legitimate need exists. Presently, the Government anticipates this to be the last contract issued off this PSL. The PSL will be used as a vehicle to solicit several stand-alone "C" type construction contracts where the high-end of any single contract is not expected to exceed $100M at this time. This, however, does not preclude the Government from soliciting and awarding a contract in excess of this amount if determined to be in the Government's best interest. After the PSL is established, the Government intends to proceed by issuing solicitations using FAR Part 14 procedures (i.e., Invitation for Bid (IFB)). However, the Government reserves the right to issue solicitations using FAR Part 15 (i.e., Contracting by Negotiation (i.e., Best Value using Lowest Price Technically Acceptable up to and potentially including Trade-Off)) when determined to be in the Government's best interest. The SPK projects that are likely to be constructed under stand-alone contracts that will be advertised to the firms on the PSL include cutoff walls using conventional, Deep Mix Method (DMM) / Deep Soil Mixing (DSM) / Cutter Soil Mixing (CSM) / One Pass Trenching (OPT) / or Trench Cutting ReMixing Deep Method (TRD) methods and conventional materials including soil bentonite and/or slag cement-cement bentonite. Projects will be located within the Sacramento Valley with a particular focus on levee improvements on the Sacramento and American Rivers. The North American Industry Classification System (NAICS) code for procurements offered to firms on the Prequalified Sources list is 237990, Other Heavy and Civil Construction, which has a small business size standard of $39.5M. Bonding Requirements: Pursuant to the Miller Act, Performance and Payment bonds shall be provided for each project awarded under the PSL. Notice to Proceed (NTP), will not be issued until after the successful bidder or offeror provides sufficient bonding to cover the work required as communicated under the project solicitation. To be considered qualified for the PSL, firms must meet the following minimum requirements: The Contractor's company, subcontractor, joint venture partner (JVP), or merged company (MC) must have experience in cutoff walls used for seepage control within the last ten (10) years from this announcement. Multiple headings on any one contract must be considered as one construction project experience. 1. Conventional slurry supported cutoff wall construction project experience must include using long-reach excavators or clamshells and include at least two (2) soil bentonite (SB) cutoff walls and two (2) slag cement-cement-bentonite (SCCB) completed cutoff wall projects. This may be submitted in four separate projects or as little as two projects if each project includes one SB and one SCCB wall within it. For each of the four (4) different experiences demonstrated the following cutoff wall standards must have been met to demonstrate sufficient capability: A minimum of 50 feet deep; o A minimum of 24-inches wide; o A minimum of 500 feet long; o A maximum permeability of 1x10-6 cm/sec for SB cutoff walls; A maximum permeability of 1x10-6 cm/sec for SCCB cutoff walls at the end of the curing time period specified in the project's contractual requirements; and o The SCCB cutoff wall must have had a minimum unconfined compressive strength of 50 psi at the end of the curing time period specified in the project's contractual requirements. Deep Mix Method (DMM) cutoff wall construction project experience must include at least one in-situ soil mixing methods classified as: 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 manual Deep Mixing for Embankment and Foundation Support. This experience must also include completed construction of at least one (1) DMM cutoff wall projects including, but not limited to, Deep Soil Mixing (DSM) / Cutter Soil Mixing (CSM) / One Pass Trenching (OPT)/Trench Cutting Re-Mixing Deep (TRD) method cutoff walls. This experience must include setting up and operating the batch plant and delivery system to the cutoff wall location, and all associated work with constructing the cutoff wall. The submission for the following cutoff wall standards must have been met to demonstrate sufficient capability: o A minimum of 75 feet deep; o A minimum of 24-inches wide; o A minimum of 500 feet long; o A maximum permeability of 1x10-6 cm/sec; and o A minimum unconfined compressive strength of 50 psi at the end of the curing time period specified in the project's contractual requirements. Earth Embankment Construction Project Experience must include construction of at least one (1) project that included placing at least 50,000 cubic yards of engineered fill for flood control levee, earth dam, or earthen embankment for water retention or conveyance, completed in the last five (5) years. 4. Jet Grout cutoff wall construction experience must include successful completion of a cutoff wall using jet grout elements (columns and panels). Experience using jet grout column and panels must be shown around/under utilities or structures sensitive to movement. Methods used may be either single fluid (grout) or triple fluid (water, air, grout). Single fluid, or no compressed air jet grouting, is defined as jet grouting where no compressed air is used during the drilling or injection stage. Triple fluid jet grouting is a system in which the jet grout rods are designed to simultaneously inject three different fluids through horizontally projecting nozzles, in which a cone of compressed air shrouds a high velocity water jet, with the third fluid being high speed cement grout jet. The rods are advanced into the ground, lifted at a constant speed while horizontally injecting grout, rotated 360 degrees for columns, and mono-directional or rotated about a fixed arc for panels. This experience must include setting up and operating a batch plant, pumps and delivery system, and jet grout drill rig at the cutoff wall location. Contractor must show capability to provide a soil cuttings containment system. One (1) project must be submitted showing jet grout column installation around/under utilities or structures sensitive to ground movement. The utility or structure must be at least 36 inches in diameter or width. The method used to monitor movement of the utility or structure must also be provided. Example projects with larger utilities or structures preferred. The method of contractor selection has not been determined at this time.
