Designing ground gas protection systems following the guidance in BS8485 is more than just adopting a Characteristic Situation and adding up points. It requires a detailed justification for any gas membrane and calculations for any underfloor ventilation system that is specified. The points assigned to the floor construction should also be justified. The design should be summarised and explained in design report and shown on detailed site specific drawings for construction.
This training will explain in detail the factors to be considered and how to complete the appropriate venting calculations. It will explain the details to be included in a design report with reference to relevant clauses in BS8485. The standard also recommends that the design report should include the verification plan for the proposed system. The course will also explain when Detailed Quantitative Risk Assessment (DQRA) might be used in place of the simple empirical points system.
