Each edition digs into one test or one design decision. Written by engineers for engineers, with a source for every figure quoted.
The technical bulletins bring together, in two pages, what Damasco Penna has learned in the field and in the laboratory about a specific test or a design decision. Each edition carries an objective data sheet, numbered sections, a technical note and the reference standards. When the topic has a matching service, the bulletin is also offered on that service's page.
The first editions cover undisturbed sampling, the limits of the piezocone, multifunction rigs and the Marchetti dilatometer test.
