**Geotechnical Soil Sampling Report** **Project Name:** Dvdatum **Location:** Texas **1. Executive Summary** This report presents a thorough geotechnical analysis of soil samples retrieved from the Dvdatum project site located in Texas. The primary aim of the investigation was to understand the subsurface soil conditions and its suitability for construction. The soil profile comprises two distinct layers of gravel and clay, each displaying different characteristics. **2. Project Information** * **Project Name:** Dvdatum * **Location:** Texas * **Start Date:** October 28, 2025 * **Description:** A comprehensive soil sampling project to determine the underlying soil characteristics at the project site. **3. Sampling Methodology** The sampling was performed using the Standard Penetration Test (SPT) in accordance with ASTM D1586. The process involved driving a split spoon sampler into the soil at specified intervals to retrieve samples. The samples were then sealed, labeled, and transported to the laboratory for further analysis. **4. Detailed Soil Profile** * **Sample 1:** * **Depth:** 0.00 - 12.00 feet * **Soil Type:** Gravel * **Color:** Gray * **Moisture Content:** 20% * **Sampled By:** Sugam * **Sampled At:** October 28, 2025, 04:19 * **Sample 2:** * **Depth:** 12.00 - 18.00 feet * **Soil Type:** Clay * **Color:** Dark brown * **Moisture Content:** Dry * **Consistency:** Soft * **Sampled By:** Sugam * **Sampled At:** October 28, 2025, 06:15 **5. Soil Classification and Characteristics** * **Sample 1:** The upper layer of the soil comprises gray gravel with a moisture content of 20%. As per the Unified Soil Classification System (USCS), this soil type is categorized as well-graded gravel (GW). * **Sample 2:** The lower layer of the soil is dark brown clay. It is dry and has a soft consistency. According to the USCS, this soil type is classified as lean clay (CL). **6. Observations and Findings** The soil profile at the Dvdatum project site is heterogeneous and consists of two distinct layers. The upper layer of gravel suggests good load-bearing capacity. The lower layer of clay may pose challenges due to its shrink-swell properties and low shear strength. **7. Recommendations** Based on the soil profile, it is recommended to consider the following: * Incorporate soil improvement techniques like vibro-compaction or stone columns for the clay layer to improve its load-bearing capacity. * Conduct further tests like Atterberg limits and shear strength for the clay layer to understand its behavior under different conditions. * Ensure appropriate drainage measures are in place to manage the moisture content in the gravel layer. This report provides a preliminary understanding of the soil conditions at the Dvdatum project site. Detailed geotechnical investigation and analysis are necessary for comprehensive site characterization and design recommendations.
