The most common strengthening solutions, triggering certain seismic protection levels, imply high costs. Taking into account the large number of churches for which rehabilitation is necessary and the relatively low financial availability, the cost optimization of the rehabilitation process is being emphasized. This paper presents a case study consisting of a decayed old church built in the XIXth century, for which, different levels of structural rehabilitation are analysed, leading to a gradual increase of the seismic protection level. Also, the execution costs are appraised for each seismic protection level. Based on the provi...

This procedure consists in applying the results provided by the rebound hammer (RH) and the ultrasonic pulse velocity (UPV) methods, in specific analytical models. Generally, the results provided by the combined method are more accurate than those given by either UPV or RH methods. The analytical models that are used for the SonReb are developed empirically and consist in regression mathematical principles. This paper is structured in two parts: the first one presents the general principles and the main advantages of the SonReb method, while the second part focuses on checking the accuracy of the existing analytical models. For this reason, 11 empirical mathematical equations frequently used in the estimation of the compressive strength values of concrete elements, have been selected. The variables of the mathematical equations are only referring to t...

Lack of management principle and inadequate quality (Koskela, 1993). For company ISO certification, one aspect is caused of fault the quality management standard usage from all level management (Speech of Prof. Puti Farida Marzuki, ITB) explained that construction managementis needed toensure the efficiencyandproductivity ofa construction projectto meetthe expectationsandrequirements established. For fulfill those aspect the leader of company need to give consideration to all level management. Some literature and data analysis found that there are many correlation between Organizational Structure performance and Quality Management System which impact some quality problem. This studies based on perspective of Romanian Law for construction quality (LAW NO 10/1995-On Quality in Construction), UU RI No 18/1999 Indonesian construction company and theirs relationship with the ISO 9001-2008 practices.
