SF-1449 This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. FARGO-MOORHEAD METRO FLOOD RISK MANAGEMENT PROJECT SCOPE OF WORK DESIGN SOIL EXPLORATION PHASE 2 UNDISTURBED LABORATORY SOIL TESTING General Description of Work: The US Army Corps of Engineers (USACE) will be conducting soil borings in the Fargo-Moorhead metro area for the Fargo-Moorhead Metro Flood Risk Management (FMMFRM) Project. During the exploration, the USACE will collect undisturbed samples (5-inch or 3-inch tube samples) which require laboratory tests to be completed on them. In addition, the USACE will be collecting bag samples on material that will be used for construction. The Contractor shall perform the following laboratory soil tests indicated in the table below. The table lists the type of tests, the American Society for Testing and Materials (ASTM) procedure associated with each test, and the number of tests. Triaxial and/or Direct Shear Tests: The Contractor shall assume that all triaxial and direct shear tests consist of three (3) specimens per test. The Contractor shall determine the initial moisture content and dry density for each triaxial specimen along with the moisture content and dry density before shearing of the specimen starts. Consolidation Tests: Consolidation tests will include determination of an initial moisture content and dry density. The consolidation test shall include an unloading and reloading schedule (where the pressure on the soil is halved) occurring 1 to 2 load increments after the preconsolidation pressure has been exceeded. At the completion of the loading schedule, the sample shall be unloaded (each successive load can be 1/4th of the preceding load). Other Tests: Any other index testing associated with triaxial or consolidation testing, such as Atterberg limits, grain size analysis, or specific gravity, will be considered not included and requested separately. Compacted Specimens: The Contractor shall assume the Standard Proctor tests are conducted on bags samples of silty clay, clay-like materials. The Contractor shall complete the standard proctor test to determine the optimum water content and maximum dry density of the soil sample. The Contractor shall use the same sample material when preparing the compacted triaxial specimens. The compacted specimens shall be prepared such that they are compacted to 95 percent maximum dry density and at a water content 3 percentage points above the optimum moisture content as obtained by the Standard proctor test. The Contractor shall assume that all compacted triaxial tests shall consist of three (3) compacted specimens per test. Laboratory Requirements: The laboratory shall be USACE validated for the tests that are required. The laboratory must be capable of running triaxial compression tests on samples up to 4-inch diameter and have at least 5 years of experience in performing triaxial testing. To minimize the disturbance of the samples, the US Army Corps of Engineers (USACE) will deliver the samples to the laboratory and the testing must be performed locally at the laboratory the samples are delivered to; samples shall not be shipped to another office. For this reason, the laboratory shall be located within the Fargo-Moorhead metropolitan area or within 25 miles of the St. Paul District Office, 180 5th St. East, Suite 700, St. Paul, MN 55101. The undisturbed samples submitted for testing will be either 5-inch diameter or 3-inch diameter thin-walled tubes and the laboratory must be capable of extruding these samples. The government reserves the right to be present at the laboratory when samples are being extruded. The laboratory shall retain the remaining portion of the samples not tested and preserve them in a temperature and humidity controlled environment that would allow for retesting of the sample at a later date. The laboratory shall retain these samples through the life of the contract and may dispose of them when contract is officially closed out. All testing must be performed at the USACE validated laboratory and be completed within 2 months from the receipt of the samples. Execution: The USACE will begin the soil exploration program in September 2014 and it will go through August 2015. The Contractor shall expect to receive samples periodically throughout this period, the majority of the samples between October 2014 and March 2015. The Contractor must be capable of completing the testing and providing results within 2 months from the date a sample is received. Upon receipt of the samples, the Contractor shall provide the USACE a schedule for when samples will be prepared, tested, and completed. The Contractor shall provide an update to the schedule bi-weekly. The Contractor shall provide the testing results to the USACE electronically, via email, when the tests are completed and reviewed by the Contractor. The Contractor shall sign the reports to indicate that the reports have been reviewed. The electronic files shall be PDFs of the testing reports. The reports shall only report the sample results associated with a single sample. Multiple sample results shall not be documented together. The USACE reserve the right to require the Contractor to revise the reports if errors and omissions are found and resubmit them. In addition to providing PDFs of the reports, the Contractor shall also provide the results of the Atterberg and particle size tests in a format such that the results can be imported into a gINT project. The format maybe a gINT project file or a formatted Microsoft Excel file. The required format of the Microsoft Excel file is attached. The Contractor shall coordinate with the USACE technical point-of-contact on the format and delivery of the test results. Report Requirements: The Contractor's test reports shall at a minimum include the information as required by the associated ASTM standards. In addition, the USACE requires the following additions and/or format to the test reports: Photo of the specimen after extrusion and photos of the triaxial specimens after shearing is completed (the photos of the sheared specimens can take the place of the sketch or can be in addition to the sketch). Pressures associated with triaxial tests reported in tons per square foot (tsf). The readings taken throughout the test (i.e. stain, deviator stress, and pore pressure (when applicable), dial readings, deflections, etc) and the reduced data shall be provided in tabulated form. Payment: The Contractor must quote a unit price for each type of test or service listed above, along with the total price per test type (unit price x number of tests. The Contractor will be paid based on the quantity of tests completed. The Contractor can will be paid for all testing that has been completed and for which laboratory test results have been received. When submitting the bill, the Contractor shall provide a list that indicates what samples and what tests have been completed and reported to the USACE Technical Points of Contact: The US Army Corps of Engineers technical Points-of-Contacts are: Kurt Heckendorf at (651) 290-5411, kurt.a.heckendorf@usace.army.mil Grant Riddick at (651) 290-5599, (651) 769-3499/cell, grant.a.riddick@usace.army.mil
