Sociedad Portuaria Caldera Granelero (SPGC) contracted Royal HaskoningDHV for the detailed design and site supervision assistance for the construction of a new multi-purpose jetty, mostly for the importation of dry bulk cargo. This project in Puntarenas, Costa Rica, was at a total cost of $35 million USD, with $556,000 USD in consultancy fees for RHDHV’s element, which was carried out from 2012 to 2015. The jetty is suitable for receiving large Handymax ships (with a dredged depth of MLWS-13.0 m) and is designed to support mobile harbour cranes for handling of containers, grain and other cargo. 

The tasks that Royal HaskoningDHV executed were:

  • Supervision and interpretation of soil investigations;
  • Layout and sizing of the jetty, based on functional requirements;
  • Detailed design of the jetty, including piles and concrete deck;
  • Preparation of Tender Documents and tender evaluation
  • Supervision of pile tests, to establish detailed pile driving criteria;
  • Adaptation of the structural design in corporation with The Engineer on site and Contractor;
  • Final inspection of the works.

One of the major challenges on the project was the geotechnical and foundation design, as Caldera is located in an area with a high seismic risk which had to be taken into account for the design. In this case we used a combination of our local experience in a seismic region and our worldwide expertise to find the best and most practical solution for the engineering challenge.

Royal HaskoningDHV was constantly in close contact with the Client during the project, with the project eventually being executed within budget and on time. Of this project, Jan-Willem Jongbloed, Regional Manager in Latin America, said “The client has said we did an excellent job on this project as they and the local authorities were very satisfied with our design and the end-product that was built on the back of that design.”
