Solicitation / RFP / RFQ

This solicitation is for the excavation of a historically significant debris site (1941-42) uncovered during KC46 Beddown operations at the Two Bay Hangar Waste Pile Site. The work involves evaluating the site's National Register of Historic Places (NRHP) eligibility, cataloging items, and defining the deposit.

• Task 1: Pre-Field Preparation and Surface Survey: Collect relevant background data, documents, maps, and reports. The March ARB Cultural Resources Manager will provide available installation records.

• Task 2: Fieldwork: Sort through existing debris piles, perform excavations in a trench (approximately 150 ft long, 10 ft wide, 10 ft deep), and analyze stratigraphic layers. The excavated area may contain up to 6000 cubic yards of removed soil. Artifacts of interest will be collected, cleaned, analyzed, and photographed. Documentation includes detailed mapping, profile drawing, and photography.

• Task 3: Reporting: Prepare a brief technical report detailing the project, activities, findings, methods, and an NRHP eligibility recommendation.

• Period of Performance: June 8, 2026, to June 26, 2026.

Statement of Work (SOW)

To conduct Section 106 studies in support of the KC-46 Beddown Project at March Air Reserve Base (ARB) to assess potential adverse effects on historic properties due to the discovery of an archeological site during construction.

• Site Assessment: Evaluate a newly discovered debris deposit, potentially a WWII era trash burn pit, dating between 1941-1942. The excavation area is approximately 150 feet long, 10 feet wide, and 10 feet deep.
• Hazardous Materials: Laboratory tests confirm the debris exceeds California toxic hazardous waste thresholds for lead and cadmium, but not federal thresholds. Approximately 6,000 cubic yards of soil were removed prior to testing.
• Safety Requirements: All personnel must be HAZWOPER certified. A remediation plan addressing protocols for identifying and evaluating historical archaeological deposits within contaminated areas must be incorporated.
• Tasks:
  • Pre-Field Preparation: Collect relevant background data, documents, maps, and reports.
  • Fieldwork: Determine spatial distribution of archaeological interest, analyze stratigraphic layers, and gather data from excavated soil piles (up to 6000 cubic yards). Artifacts of interest will be collected, cleaned, analyzed, and photographed. Detailed documentation (mapping, profile drawing, photography) of the site and artifacts is required.
  • Reporting: Prepare a technical report detailing the project, findings, methods, historical significance, and NRHP eligibility recommendation. Include an appendix with California DPR 523 forms and obtain necessary "P-numbers" and trinomials.
• Geospatial Data: Digitize excavation units for the March ARB GIS Excavation Units layer and submit all other GPS/GIS data according to March ARB Spatial Data Submittal Standards.

Not explicitly stated, but the project is for March Air Reserve Base, Riverside County, California.

• HAZWOPER certification for all personnel working in the excavation area and with removed soil materials.

• Deliverables must be property of March ARB and not distributed without written permission.

• Electronic deliverables must be in Microsoft Word and Adobe Acrobat (unsecured) formats.

• All GPS/GIS data must adhere to March ARB Spatial Data Submittal Standards.

• Draft Report (2 hard copies, 1 unlocked e-copy)

• Final Report (3 hard copies, 2 e-copies, one unlocked)

• Final Geospatial Data (1 e-copy)

• DPR Forms (2 hard copies, 1 e-copy)
