The Institute of Engineering has participated as an advisor agency for the construction of the viaducts of the new and first high speed railway project in Mexico. In this paper we present different tasks that we have carried out for the Ministry of Communication and Transportation in order to validate some structural design and environmental assumptions. The activities comprised the review of the seismic spectra, instrumentation and load testing of large foundation piles, quality assurance for the construction of a box steel superstructure, ambient vibration of piers and the evaluation of noise vibration related problems. Each one of these tasks will be described as well as a general presentation of the project.
