Standard prefabricated stone structures of the Peter's the Great Docks

Standard stone structures of the Peter the Great Dock in Kronstadt is considered in this article. Stairs in the dock had been made from timber and subsequently there was a need for their reconstruction, which started in 1850s. This event became main catalyst searching optimal solution for a difficult task for those times. Standard stone structures were chosen as the most reliable and cost-effective option, under the conditions of complex logistics and the marine climate of the island. On the example of reinforced concrete patches, which were installed during the subsequent reconstruction of the dock, the theme of the advantages of the strength characteristics of stone materials compared with reinforced concrete is considered. This comparison shows that under modern conditions and more advanced technologies that reduce the cost of processing large blocks of stone and their installation with transportation, stone structures can compete in the market with traditional wood and concrete
