Dd Form 1206 PDF Details

In the realm of geotechnical engineering and construction, the DD Form 1206 plays a critical role. This form, dedicated to Grain-Size Analysis through the Sieve Method, encompasses a comprehensive approach to evaluating soil samples. It begins by cataloging basic information such as the project name, date, job number, and excavation details, then delves deeper into the specifics of the sample under examination, including its number, original and post-wash weights. The form meticulously records data on the sieve process itself—sieve sizes, weights before and after sieving, cumulative percentages, and the weight retained or passed through each sieve—yielding an accurate depiction of the sample's grain size distribution. Such analysis is essential not only in assessing the suitability of soil for construction projects but also in understanding its behavioral characteristics under various conditions. Additionally, the form accounts for potential errors and wash losses, ensuring a thorough and precise evaluation. The involvement of multiple technicians in the filling, computing, and checking of this form underscores the importance of precision and reliability in the field's foundational data gathering efforts.
