Quality Control Plans for Girder and Frame Bridges

Abstract

Infrastructure Managers works every day according to some kind of Quality Control Plan (QCP) in order to ensure a desired quality with minimum traffic interruption balancing cost, risks (implicit or explicit) and performance. These QCPs varies significantly among European countries, which urges the establishment of a common European guideline. COST TU1406 Working Group 3 has the aim of providing a detailed explanation of the steps towards the establishment of a QCP. The approach is generic and evaluates performance values with due attention to: 1) Structure and its constitutive element incl. background material such as birth certificates, 2) Time-dependent Performance Indicators (PI) from observations (e.g. spalling) with due reference to the underlying deterioration processes (e.g. alkali-silica reaction) and 3) Related Key Performance Indicators (KPI) based on the Dutch risk-driven maintenance concept RAMSSHE€P, ref. [1]. This paper outline QCP's for concrete girder and frame bridges.
