Project data

Location: Vila Real – Alijó, Portugal

Construction period: 2011 - 2016

Requirements

  • 108-m-high double curvature dam wall
  • 5-m-wide and 275-m-long dam crest with complex design due to integrated overflow mechanism
  • Tunnel formwork carriage for two 700-m-long pipes for the hydraulic circuit

Customer

Barragem de Foz Tua, ACE
Consortium of Mota-Engil S.A., Somague S.A. and MSF S.A

Customer's benefit

  • Precise construction of the dam wall, the complex dam crest, the intake and discharge facilities and the tunnel for the hydraulic circuit
  • Accelerated working through use of large climbing units with safe, convenient working platforms
  • Best architectural concrete results with the project-specific, modified, extremely flexible VARIO GT 24 Wall Formwork
  • Simplified site supervision thanks to continual coordination of all project participants and constant optimisation of material volumes on the construction site by the PERI Project Manager
  • Compliance with the construction schedule and cost plan due to smooth progress of all processes and work using the formwork and scaffolding technology

Site Manager

The support provided by the PERI design engineer directly on the jobsite along with the constant contact to his technical office ensured that all project members could work together in order to develop the best formwork solution for this complex project. Without this close collaboration, it would not have been possible to maintain the construction schedule. PERI ensured the best on-site formwork and project management through constantly adapted material quantities and schedules as well as close coordination with all construction crews for carrying out the wide range of formwork operations. This helped us to guarantee project profitability in terms of time and costs.

PERI solution

  • Project-specific modified complete solution of SCS 190 Climbing System and VARIO GT 24 Wall Formwork for the double curvature dam wall
  • Special solution of SB-0 Brace Frames, system components from the VARIOKIT Engineering Construction Kit and MULTIPROP Shoring Towers, and VARIO GT 24 Elements for the dam crest with overflow mechanism
  • TRIO Wall Formwork for less complex wall structures around the dam galleries
  • PERI UP Modular Scaffold for diverse falsework and working scaffolding and access solutions
  • Steel formwork carriage for the pipes of the hydraulic circuit
  • Supply and provision of enormous volumes of material
  • Elaborate concept, logistical and technical services from one source
  • Local PERI Project Manager for detailed coordination of all processes relating to planning, logistics and formwork assembly during each construction phase
