0320 - Rosena Ranch Fire Station

Background
The Rosena Ranch Fire Station and Small Sheriff’s Station Annex project is located in an unincorporated area of San Bernardino County, California. The project aims to provide essential emergency services and infrastructure to the community.

The geotechnical investigation and water percolation test report was prepared by Converse Consultants to assist with the design and construction of the facilities, ensuring that the site is suitable for the proposed structures.

Work Details
The scope of work includes a comprehensive geotechnical investigation involving subsurface exploration, percolation testing, laboratory testing, and engineering analyses. Specific tasks include:
- Project set-up including site reconnaissance and marking exploration locations.
- Subsurface exploration through exploratory borings (BH-01) and test pits (TP-01 to TP-08) to assess soil conditions.
- Percolation testing conducted in three test pits (PT-01 to PT-03) to evaluate water infiltration rates.
- Laboratory tests performed on soil samples for expansion index, R-value, grain size distribution, maximum dry density, optimum moisture content, and direct shear strength.
- Recommendations for earthwork including overexcavation depths for foundations and slabs-on-grade based on soil conditions encountered.

Period of Performance
The geotechnical investigation was completed with fieldwork conducted in December 2023. The report was finalized on February 26, 2024.

Place of Performance
The contract will be performed at the Rosena Ranch Fire Station site located at Lytle DC APN-023905415 in San Bernardino County, California.
