The Smithland hydroelectric power plant is equipped with 3 turbines; due to the extremely tight construction schedule, all three tubes with their constantly changing cross-sections are being realized at the same time.

Project Information

Requirements

Extremely tight construction schedule of 18 months, resulting in simultaneous realization of the three turbine tubes and other components Massive components with long utilization period of formwork and scaffolding resulting in high material requirements (provision for some areas 100 %) Very complex forms, in particular for the turbine tubes as well as the intake structure with varying cross-sections Very strict guidelines regarding the dimensional accuracy

Solutions

Development of a comprehensive concept for the formwork and scaffolding technology while taking into account all project requirements as well as budget and schedule considerations 3D planning of multi-curved formwork units for the complex forming of the tubes for the turbines Dimensionally accurate realization and delivery of the 3D formwork units Delivery of the elements in pre-assembled units Continuous coordination of all formwork and scaffolding processes through a PERI project manager on site
