Inspection
Publisher: Prof. Dr.-Ing. Stein & Partner GmbH (2016)
The construction of sewers is often carried out using the open construction method. Depending on the design, this results in pipe-soil systems with different external loads on the sewer. To understand these relationships, the soil mechanical and hydrogeological principles for characterizing the subsoil are explained.
After completing this module, you will have a sound knowledge of how:
- To differentiate between soil types;
- To identify the influences of grain shape and grain size distribution on the practical construction properties of the subsoil and
- To name the different appearances of water in the subsoil;
- To determine the water permeability of the soil for a constructional assessment of the soil.
The documentation of damages, defects, other peculiarities (findings) in sewers and pipes within the scope of CCTV inspection is not possible without a uniform nomenclature. In Europe, EN 13508 Part 2: "Coding system for visual inspection" provides the normative basis for documenting and describing various findings, which later serve the engineer as a basis for assessment.
This module provides the basic knowledge required for the structure and application of the coding system.
LEARNING OUTCOMES
- coding system according to EN 13508-2;
- differentiation between basic information and findings;
- differences in the coding system between sewers and manholes;
- codes for route finding, tightness indication, location on the circumference and
- procedure of inspection in an object.

This lesson builds on the module "Application of coding systems using the example of EN 13508-2" and introduces the coding of damage (findings) for sewers and drains. In more detail, the causes and consequences of damage are explained for the damage and, in some cases, the damage mechanisms are presented as well.
LEARNING OUTCOMES
- apply the coding system according to EN 13508-2
- classify damage
- name causes and consequences of damage

This module teaches the basics of geotechnical investigations for civil engineering purposes. The described subsoil investigation by indirect (e.g., drilling methods) and direct exploration methods (e.g., dynamic sounding) form the basis for an understanding of a civil engineering description and evaluation of soil and rock.
LEARNING OUTCOMES
- The objective of a geotechnical investigation;
- The purpose of structural and subsoil investigation by means of excavations;
- Differentiation between direct and indirect excavation methods, such as drilling methods and indirect excavation methods, such as dynamic sounding.

Large profiles and wastewater structures were manufactured on site in the past. Various methods and construction materials were used for this purpose. Professional maintenance of these structures requires a detailed understanding of the construction materials used and the manufacturing processes applied. This module provides the necessary basic knowledge for this understanding. Learning objectives:
After completing this module, you will have a sound knowledge of:
• Construction methods for large masonry profiles; • Typical damage to large profiles; • Special aspects of condition assessment for structures and large profiles; • Design and implementation of an extended investigation programme for condition assessment, classification and evaluation; • Design of an extended structural stability assessment.
This module teaches the basics of geophysical soil investigation and is to be understood as a supplement to the module "Geotechnical Investigation". Geophysical measurement methods belong to the indirect exploration methods and allow statements regarding local inhomogeneities in the pipeline zone (e.g. bedding defects, cavities, disruptions, concrete encasements) or, in the case of investigations of existing sewers and pipelines, statements regarding the condition and load-bearing capacity of the embedment. In addition to ground or georadar (EMR - electromagnetic reflection), which is well-known in pipeline construction and rehabilitation, the measurement methods seismic, seismic tomography, air gun seismic, magnetics, electromagnetics and geoelectrics are also introduced.
LEARNING OUTCOMES
- Procedural principles and
- Assignment of application areas to procedures of geophysical ground investigation.
