Ventilation and Sewerage. As it is

This presentation was presented by me to 688 employees of the largest international developer at the corporate university,
as part of the training on ventilation and sanitation (35 training sessions, 8 hours each).
The presentation contains information on the main problems encountered in the service of residential complexes in the form of cases.
The purpose of the training is to prevent these problems by drawing the attention of designers, builders, engineers and management personnel to the main points.
The presentation contains both practical and theoretical material.
This material is suitable for both students and beginners, as well as experienced builders.
The presentation provides an opportunity to learn basic knowledge about ventilation and sanitation in residential complexes in a short time.
