This effort will be issued based on the number of site forms required for the evaluation as identified by the Government in the Task Order. The Government will identify those properties that can be grouped together on site forms in order to facilitate survey and evaluation. Prior to Task Order award, the Government shall identify these groupings and determine the maximum number of site forms required on the basis of factors such as construction dates; function, size; architecture; potential eligibility, and common recordation practices within a given State. In developing the maximum number of site forms required for a Task Order, the Government will also take into consideration the number of resources to be grouped on a single site form and the level of effort required to survey and record individual properties, if they are not of duplicative types.

A. Field surveys and resource recordation. The Contractor shall conduct field surveys that include locating, inspecting, and photographing each property identified in the Task Order as part of the survey and evaluation. The Contractor shall completely and accurately record all data required for each site form as specified for each State(s) referenced in Annex 2, Spec Item 2.5.2.1 where the work will be performed. The inventory data, at a minimum, shall include the building/facility number; year built; year altered or improved; dimensions; historic function(s), and current function.

The Contractor shall also record relevant observations on each resource’s potential integrity and property type. The Contractor’s inspection and photographic effort shall also consider the potential for interior features to be considered as characteristics that qualify a historic property for listing in the NRHP. Photographs and descriptive data are to be recorded for all interior features identified as character defining. The Government will provide available iNFADS real property inventory data to facilitate fieldwork.

B. Historical Research. The Contractor shall conduct historical research to develop a thorough and accurate historical context statement, relevant historical theme(s) and period(s) of significance, a discussion of property types, resource descriptions, descriptions of historic function(s), and the evaluation of eligibility. As appropriate for each project, the Contractor shall gather and analyze data from or conduct research at appropriately relevant repositories, such as the installation’s Public Works Office or Public Affairs Offices, local libraries and/or archives, the Naval History and Heritage Command, US Navy Seabee Museum at Naval Base Ventura County, and/or the relevant National Archives regional branch.

The Contractor shall develop a historical context utilizing relevant previous investigations, context studies, secondary sources, and available archival repositories with primary sources, such as maps, drawings, command histories, newspapers, and other relevant sources. The historical context and subsequent evaluations must utilize information about historical trends and properties grouped by an important theme in the history of a community, state, or the nation during a particular period of time.

C. Site Forms and updates. The Contractor shall prepare new and/or updated site forms in accordance with the State guidance and requirements referenced in Annex 2, Spec Item 2.5.2.1 and as they apply to recording historic resources.

Areas of multi-loci sites between loci with surface-only deposits, or accountable as transported materials, may be augered at up to eight meter (8 m) intervals (on a 16 m grid) until discrete sub-surface deposits are again encountered at which point the interval returns to that prescribed for the associated locus’s size.

4. Test Units. As specified in the individual Task Order, the contractor shall conduct excavation testing of project sites to assess site integrity, quantify archaeological data sets appropriate to the criteria for National Register eligibility, and recover carbon-source samples for 14C dating. Determination of whether and where to test excavate a site's deposit shall be based in an assessment of observed surface and/or auger data for the locations of concentrated subsurface cultural materials.

5. The test unit dimensions are 1 m x 1 m, but can be specified in the individual Task Order as 0.5 m x 1 m units in a number equivalent to the cumulative areas of the 1 m x 1 m units required for a particular site/locus size category. Test units shall be excavated to the sterile substrata beneath the archaeological deposit. In each unit, soils shall be excavated in 10 cm controlled levels from an established unit datum. All excavated soils from each unit shall be screened through 1/8-inch wire mesh screen. Artifacts and ecofacts shall be collected from the screen. A unit notebook shall be maintained for each unit. This notebook shall include a level form for each excavated level in the unit. The level form shall be used to record data and observations including descriptions of soils, any observed disturbance; types and kinds of materials collected; and feature and artifact provenience. The notebook shall also include level maps where any encountered features are mapped and recorded. Sidewall profiles shall be completed for at least one representative sidewall for each unit and include observed stratigraphy, any disturbance, and soil descriptions and Munsell soil color codes for each strata. All test units shall be backfilled when excavation is complete, after photographs are taken, and sidewall profiles are complete.

Each feature encountered in a site shall be given a feature designation. Feature forms shall also be maintained for recording data, observations, and mapping for each feature.

10. Radiocarbon Samples. Samples of material suitable for radiocarbon (14C) shall be collected from features or other in situ contexts. These samples shall be handled as described in Annex 18, Spec Item 4.3, Paragraph E.

11. Pollen Samples. Soil samples shall be collected for pollen analysis from up to three of the most representational units. Immediately prior to sampling, the sidewalls are to be scrapped to remove the accumulation of modern pollen.

12. Samples shall be collected in five centimeter (5 cm) increments starting with the bottom of the unit and ending at the top of the unit. Each sample shall be approximately 200 cc or one cup (1 c). Each sample shall be placed in clear, zipper closure, polyethylene bag (Whirl-pak or Zip-lock type bags are acceptable). Each sample shall be placed in another Zip-lock or paper bag marked with the site number, unit number, level, date, and contents. Samples sizes are to be increased by 50% if soil is very sandy. All tools to be used in samples are to be wiped clean of soil. Distilled water shall be used to clean tools and wiped with a paper towel before the first sample is taken and between each sample collected to prevent contamination. Samples are to be removed and quickly secured after exposure (between 10 to 30 minutes). Each sample area is to be two centimeters (2 cm) high, rectangular and extended to the side until the volume requirement is met. Several control samples shall also be taken within a 30 m diameter around the site. Control samples are to be taken prior to any vegetation removal and before excavation. Control samples’ locations are to be indicated on the site map. The location of the pollens samples shall be noted on the sidewall profile.

13. Field Collected Materials. Artifacts and ecofacts shall be saved in plastic bags marked with indelible ink indicating site number, provenience, level, date, and contents. The collected materials shall be sorted and bagged by artifact/ecofact type (e.g. lithic debitage, bone, shell, etc.). Any fragile or perishable materials shall be handled to prevent damage and contamination as described in Annex 2, Spec Item 2.5.9.

14. Samples Collected for Special Analysis. Samples collected for special analyses including charcoal, pollen, bone or bone tools, shell, obsidian, projectile points, flaked tools, ground stone tools, etc. These samples shall be taken from an in situ subsurface deposit when possible. The items shall be handled in a manner that will prevent damage and/or contamination as described in Annex 2, Spec Item 2.5.9.

15. Protein Residue Samples. Artifacts suitable for protein residue analysis include flaked lithic artifacts, ground stone and pecked stone, ceramics, and soils. Samples chosen for protein residue analysis shall be immediately placed in clear, zipper closure, polyethylene bag (Whirl-pak or Zip-loc type bag). These samples shall be handled as little as possible and care should be taken not to introduce human protein on the artifacts. Control samples of soil from the location where each artifact is collected shall be collected. Each control sample shall be one gram (1g) in size. Stratified sites shall also require the collection of control soil samples from each level excavated and at least offsite control sample. Each control sample shall be placed in clean film canisters and marked with the provenience. Surface sites shall have one (1) to two (2) control samples from the site area and one (1) control sample from offsite. Each control sample shall be placed in clean film canisters and marked with the provenience.

16. Surface Collection. Collection of all surface artifacts shall only be required when specifically stated in the Task Order. Otherwise only temporally diagnostic artifacts shall be collected as described in Annex 2, Spec Item 2.5.9.

17. Site Mapping. A site map shall be generated for each site evaluated using survey equipment from an established site datum. Maps shall indicate locations for each surface collected artifact, STPs/Auger hole, test unit datum, and identifying geographical features near the site area. Global Positioning System (GPS) will be used at the site datum so the mapped site data can be plotted on a base map for the study area.

E. Laboratory Methods and Data Analysis. The collected material shall be handled and analyzed as prescribed in Annex 2, Spec Item 2.5.9. The Contractor shall select samples for special analysis from contexts with minimum amount of post depositional disturbance. The Contractor shall ensure that the maximum amount of data is obtained by coordinating sampling strategy between each type of analysis.
