Abstract
This research work attempts to approach the measuring of the working equipment necessary to make floating caissons for maritime work and their performances. With this objective, an empirical study has been carried out based on the construction of five floating caissons with a rectangular layout of 34.00 meters in length, 17.00 meters in width, and 19.00 meters in depth, lightened with 32 vertical cells. This work was carried out in the port of Granadilla, Tenerife (Spain). The updated scientific literature related to the execution of this type of floating structure refers to the importance of the calculation hypotheses, the actions to be taken into account, the service states or the importance of the choice of materials (concrete and steel). However, scientific research does not seem to face the problem of how to size the working team necessary to execute this type of structure. The work force is approached from the point of view of the adequate sizing of working groups. The important contribution of the article to the project and construction management literature is the development and capability of an easy-to-use optimization model for planning the labour and labour days required in floating caisson construction. The optimization model proposed in this research allows the project managers of a construction company to estimate the labour costs and teams necessary in the execution of the construction. This gives it a competitive advantage both in the construction phase and in the bidding phase for the award of the work. Doi: 10.28991/CEJ-2022-08-02-01 Full Text: PDF

Summary
Seaports are nodes that are integrated into commercial, logistical, and transportation networks. Their main function is the safe and efficient transfer of goods and passengers between maritime and land transport nodes, such as roads, railroads, and shipping routes. The service area of ports has infrastructure related to the following: (a) control of sea oscillations (breakwaters and maritime structures); (b) maritime safety and operability of the area (berthing and mooring areas); (c) land use and exploitation of the area; and (d) land transportation access modes [1]. The technology of vertical concrete walls was introduced 2,000 years ago by Roman port engineers, in contrast to the Greek tradition of rubble mound breakwaters. The first vertical wall breakwater was built with a low rubble base in Naples in 1900. Caisson breakwaters become the most suitable option [4]
