Shaft Konrad no. 1 – Shaft rehabilitation Works
The construction work described is part of the construction project for the establishment of the Konrad repository. Shafts 1 and 2 of the former Konrad iron ore mine are to be prepared for the service of a repository mine. The former ore-hoisting shaft Konrad 1 is to be used as an extraction, a men-material and a cable shaft. The Konrad 2 shaft will be used for hoisting of containers with radioactive waste.
As part of the complete redesign of the Konrad 1 shaft hoisting system, the project involves the replacement of the existing wooden shaft guides with steel guides for the future operation of a skip and a large cage hoisting system. At the same time, the pipelines and cables systems in the shaft are to be renewed or extended. In addition, the shaft stations on the 3rd, 4th and 5th levels location as well as the concrete bricks lining in damaged areas of the shaft is to be repaired. Furthermore, the surface and underground construction site facilities required for the execution of work, as well as the necessary material handling equipment, such as mobile platforms, transport and auxiliary equipment has to be designed, supplied and installed.
The contracted services essentially comprise:
- Preparation of approval planning and manufacturer-specific production planning for all facilities required for the provision of services, which are to be erected for the installation of the necessary equipment;
- Planning, delivery and assembly of the surface and underground construction site equipment, as well as all equipment required for the execution of the work, including the temporary materials handling equipment such as platform system, emergency driving system, etc.
- Preparation of the approval planning for the implementation of the construction work;
- Removal of shaft furniture from the shaft installations such as guides and buntons, power and signal cables and pipelines that are no longer required including their brackets;
- Refurbishment of the shaft lining mainly by cleaning and re-grouting the shaft masonry and backfilling niches and chambers that are no longer required;
- Assembly of the new shaft installations, pipelines and their relocation;
- Assistance with the installation of the power and signal cables;
- Installation of the shaft station steelwork, the shaft sump installations and the shaft fire doors;
- Supply of assembly and inventory documentation.
