Exploration work for the Lensky bridge began in Yakutia
The concessionaire began survey work in Yakutia for the construction of a bridge across the Lena River. Four drilling rigs were relocated to the site of the future construction site to start prospecting work “from the ice”.
Specialists received the first samples of frozen soil, they were transferred for analysis to the laboratory of the Yakutsk State Research Institute of Construction. According to the press service of the VIS company, the analysis of space stereo images has begun to determine the optimal trace and location of the bridge supports. Prior to the ice drift, thermometric columns will be installed to determine the temperature characteristics of the soil under the base of the bridge supports.
Design surveys will be held in several stages. In the summer, archaeological research is planned to discover and preserve possible cultural heritage sites in the construction zone. All work at the stage of research and design will be financed by the concessionaire.
