Laboratory Testing. Any laboratory testing necessary to conduct soils surface and subsurface characterization applicable to the needs of the project which are identified in the COUNTY approved Scope of Work or as otherwise approved by the COUNTY, will be performed by the A-E in accordance with County of Orange DocuSign Envelope ID: 96880C1C-5BFF-4A8F-84ED-12ECBD488EFAStandards and Procedures using California Test Methods (CTM) and/or American Society for Testing and Materials (ASTM) standards. Caltrans certified technicians and Caltrans laboratory certification may be required to satisfy the needs of the investigation and/or construction monitoring for all projects. All test results shall be provided as an attachment to the report.
Laboratory Testing. All drug testing will be completed in a laboratory certified by the Department of Health and Human Services (DHHS). Pace has contracted with Phamatech, Inc. (15175 Innovation Dr. San Diego, CA 92128) to conduct all drug testing administered on its behalf under this policy. As of the revised date of this policy, the Federal Register has identified Phamatech, Inc. as DHHS-certified. An immunoassay test will be performed initially on the specimen. If any prohibited drug registers above the cutoff level on the immunoassay screen, an aliquot of the same urine specimen will be confirmed by using gas chromatography/mass spectrometry (GC,MS). All FTA and Pace mandated tests will undergo validity testing which is designed to deter and detect attempts to adulterate or substitute specimens. Testing must conform with 49 CFR Part 40 as amended and effective January 18, 2001. All FTA-mandated drug testing will be performed to detect for the presence of the following five (5) substances: Marijuana; Cocaine; Opioids; Phencyclidine; and Amphetamines. The following initial cutoff levels will be used when screening specimens to determine whether they are negative for the identified drugs: 1 For grouped analytes (i.e., two or more analytes that are in the same drug class and have the same initial test cutoff):Immunoassay: The test must be calibrated with one analyte from the group identified as the target analyte. The cross-reactivity of the immunoassay to the other analyte(s) within the group must be 80 percent or greater; if not, separate immunoassays must be used for the analytes within the group.Alternate technology: Either one analyte or all analytes from the group must be used for calibration, depending on the technology. At least one analyte within the group must have a concentration equal to or greater than the initial test cutoff or, alternatively, the sum of the analytes present (i.e., equal to or greater than the laboratory’s validated limit of quantification) must be equal to or greater than the initial test cutoff.2 An immunoassay must be calibrated with the target analyte, Δ-9-tetrahydrocannabinol-9-carboxylic acid (THCA).
Laboratory Testing. Laboratory tests will be assigned corresponding to the types of soils encountered, with the objective of classifying the soils physical and index properties, moisture contents, unconfined compressive strength, undrained unconsolidated compressive strength, Atterberg limits, percent finer than No. 200 sieve, and total unit weight tests. For detention pond, ATL require advanced testing for slope stability analysis such as Consolidated-undrained Triaxial test, and soil dispersiveness tests (double hydrometer Test, Crumb Tests). All laboratory tests will be performed in accordance with appropriate ASTM standards. ATL will keep the samples for 30 days after the final report is presented. ATL will discard the samples after that time, unless instructed otherwise.
Laboratory Testing. Upon request from USGC, NMC will consider performing laboratory flotation testing to further investigate application of the NMC Flotation Technology for implementation at the Tonkin Springs Property. NMC shall have no obligation to perform such testing. But if NMC does agree to perform such testing, then USGC shall pay for such testing based on personnel, laboratory facility and other charges to be provided by NMC. NMC will provide USGC only with factual data concerning test conditions and results of the tests. USGC assumes all responsibility for interpretation of such factual data.
Laboratory Testing. All testing will be performed according to ASTM standards, where applicable, or with other well-established procedures. Laboratory testing will include classification tests such as moisture content, sample description, material diameters and color values (for sands), unit weight, Atterberg Limits, specific gravity, and sieve analysis. Strength testing will include unconfined compression, unconsolidated-undrained triaxial compression, and multi-stage consolidated undrained triaxial compression. Consolidation testing by the oedometer test method will be performed to provide data to estimate levee settlement.
Laboratory Testing. CONSULTANT will conduct laboratory tests to identify and provide data on the physical characteristics of the underlying materials, including the existing pavement section. The laboratory testing will include visual and laboratory testing to identify USCS soil classifications, natural water content, and unit weight. Additional laboratory tests will be performed on representative bulk samples that provide an accurate representation of subgrade materials to be encountered in the project site. Additional testing will include: Laboratory TestNumber of TestsParticle Size Analysis (ASTM D422)*One CBR test will include an aggregate base and asphalt concrete blend.
