Open Cut Method
This course includes tutorial services and a final examination.
The installation of water pipes, in particular, drains and sewers is worldwide in large part performed using the open cut method. This at first glance “simple” construction method is actually highly complex when used in urban areas and at large depths. The numerous boundary conditions, shoring-, and installation systems require extensive technical knowledge in order to ensure a high quality workmanship.
The course consists of 5 modules on the following topics:
- Geotechnical and hydrogeological Principles
- Utility Trench Construction
- Embedment of Piping
- Installation of Pipes
- Occupational Health and Safety around Excavations
LEARNING OUTCOMES
- Identify and apply the main rules and regulations;
- Differentiate between soil types, to identify the effects of particle shape and particle size distribution on the soil properties, to assess the ground state with respect to its bulk density and soil consistency;
- Identify the different manifestations of water in the subsurface, understand the effect of free moving underground water as a form of water permeability of the soil, and determine the water permeability of soil;
- Determine the requirements for planning, tendering and construction of the utility trench along with the required shoring components and materials;
- Identify various ways of constructing unlined trenches safely and within regulation;
- Identify the various shoring/lining systems along with their limits;
- Describe the open cut method of pipe installation;
- Identify and assess construction errors;
- Implement occupational health and safety measures for the open cut method.

The embedment consists of bedding, side filling and initial and main cover. The quality of the embedment is significantly influenced by the installation conditions of the pipes. Other topics of this module include flowable fill for trench backfill, optimized installation methods and compaction tests.
LEARNING OUTCOMES
- Rules and regulations;
- Requirements for the embedment zone and compaction of the trench backfill;
- Process sequences of the open cut method;
- Influencing factors to ensure high execution quality on the construction site;
- Recognizing and assessing errors in construction.

The construction of sewers is still often carried out in the form of open cut construction. Depending on the design, this results in different pipe-soil systems with different external loads on the sewer.
LEARNING OUTCOMES
- Rules and regulations;
- Requirements for planning, tendering and construction of the pipeline zone, the shoring and the components and building materials;
- Procedures for dewatering and
- Process sequences of the open construction method.
