Rahmenvertrag über Schweiß-und Montagearbeiten am Kesseldruckkörper

The contract starts on February 1, 2027, and initially ends on July 31, 2028. This represents an initial duration of 1.5 years. The contract includes an option for extension, where it automatically prolongs by one year if neither party expresses an intent not to continue at least six months prior to the contract's expiration. The maximum total duration of the contract, including extensions, is 3.5 years. Key milestones include the execution of work during three revisions per year at the Würzburg waste incineration plant, with revision times announced at the end of each calendar year for the subsequent year.

The core scope of work for this tender involves a framework agreement for welding and assembly work at the Würzburg waste incineration plant (MHKW Würzburg). The work primarily focuses on boiler pressure parts, high-pressure lines, and other ancillary facilities and pipelines. It is to be executed by qualified welders and fitters during three annual revision periods, as well as for on-call repair work due to breakdowns or planned modifications.

The contract is set for a period from February 1, 2027, to July 31, 2028, with the potential for two one-year extensions, totaling a maximum of 3.5 years.

Key deliverables and services explicitly stated include:

• Replacement of membrane walls.
• Replacement of various pipelines (water, steam, sewage sludge, compressed air, etc.).
• Welding tasks such as installing shut-off valves, flanges, and measuring nozzles.
• Dismantling of membrane walls and pipelines.
• Transport of components like pipelines and membrane walls within the power plant premises to the work site.
• Repairs of defective pipelines and fittings.
• Laying of pipelines.
• All necessary auxiliary work, from transporting materials from storage to the point of use, to final assembly for operational readiness, and subsequent site clearance.

Detailed tasks also include:

• Welding pipe fittings, which encompasses aligning the fitting, preparing the weld seam, and welding both connection seams.
• Welding pipes, involving aligning the pipe section, weld seam preparation, welding, and final inspection.
• Work on boiler pressure bodies, specifically weld seam preparation and welding of membrane walls, including various types of web seams and pipe-side joints, and the opening and closing of collector inspection nozzles.
