November 3rd, 2023 | 2 min. read By [Legacy Engineering](https://legacyengineering.com/blog/author/legacy-engineering) ![proctor](https://legacyengineering.com/hubfs/proctor-2.jpg "proctor") If you're planning a construction project that requires soil compaction testing, yes, we need a proctor sample from your site to ensure that the soil at your site meets the necessary density and compaction specifications. Here’s how it works at Legacy Engineering: **Collecting a Proctor Sample**: As soon as soil arrives at your site, it's essential to collect a proctor sample. This sample is a representation of the material you're working with and is key to determining if your soil meets the job site requirements. ![compaction](https://legacyengineering.com/hs-fs/hubfs/compaction.jpg?width=592&height=423&name=compaction.jpg "compaction") Legacy Engineering's lab, featuring our compaction machine  1. **Collecting a Proctor Sample**: As soon as soil arrives at your site, it's essential to collect a proctor sample. This sample is a representation of the material you're working with and is key to determining if your soil meets the job site requirements. 2. **Timing and Processing:** After collecting the proctor sample, it takes us a minimum of 48 hours to process it due to lab backlog. Prompt collection of the sample allows us to provide rapid compaction test results. 3. **Importance of a Proctor:** The proctor sample is vital for the validity of your final density report. Without it, our field technicians cannot accurately determine if your soil meets the necessary standards. The proctor test is integral in providing: Valid compaction test results. Quick delivery of your final report. Confirmation of whether your soil has passed or failed the requirements. An accurate assessment of the bearing capacity of your foundation. Assurance that your soil is strong enough to avoid future settlement and maintenance issues. 4. **Legacy Engineering’s Testing Methods: **At Legacy Engineering, we utilize a low radiation level nuclear density gauge for soil density testing. This advanced method efficiently tests the wet and dry densities, along with the moisture content of the soil, through a quick test. For an example of how we conduct these tests, you can view a [video](https://www.youtube.com/watch?v=HSGcLH4p9Cs) of one of our field technicians performing a density test at a Circle K in St. Augustine, Florida. 5. **Process and Final Report:** While it’s possible to perform the proctor and density tests simultaneously, this might delay your final report. Our lab first runs the proctor to compare field densities to the proctor numbers, ensuring that the tested locations meet your job site specifications. Without a proctor, it’s impossible to ascertain if your site's soil meets the necessary requirements. In summary, the proctor test is an essential part of ensuring the success of your construction project by confirming the quality and suitability of the soil at your site. At Legacy Engineering, we prioritize accurate and efficient testing to help keep your project on track and up to standards. Ready to ensure the quality and safety of your project?
