Buildings: EXPO02 Piazza Pinocchio

Case study: SOFO, ADAM System

Steel piles load monitoring
Thermal-induced strain compensation
Warnings and pre-warnings
Phone call advises on warnings threshold over passing

Project Description

Summary: Monitoring of the live loads from visitors on a steel-timber platform, automatic and remote operation, generation of warnings

Clients: EXPO02

Place: Neuch?el (Switzerland)

Period: 2000 - 2002

Installation: Smartec

Structure's short description: The ?Piazza Pinocchio? has been built together with other exposition buildings on one big artificial peninsula. The belly of the whale holds the exposition dedicated to robotic and the rest of the village has been developed on two floors with steel piles, beams structure, wood walls and floors.

Aim of monitoring: Real-time computer-screen picture-form results of the live loads during 18 hours a day Automatic thermal-induced strain compensation Rreal-time warnings and pre-warnings for each single pile Automatic phone call advises on warnings threshold over passing and remote monitoring for complete management of the monitoring system.

Number of sensor: 31

Main Results: The plaza has been equiped with 31 SOFO standard sensors and 31 thermocouples. On site, Security will receive a phone call from the Smartec system in case of overpassing of pre-warnings and warnings. From Smartec's office, our IT engineer is able to completely controle the plaza monitoring.
