The T5 Terminal – 80% of land reclamation works completed

At the construction site of the T5 terminal in the Baltic Hub, the land reclamation works have entered the most important stage of implementation. Modern equipment is used, including Van Oord suction dredgers and self-propelled hopper barges. At the current stage, the progress of these works is 80%, and the work is being carried out in parallel on many jobsites, with high intensity and full control over each stage.

Within the planned storage and manoeuvring yard (with a total area of approximately 21 hectares), works related to the preliminary assembly of individual wind farm components will be carried out.

The project includes the construction of two transhipment quays, as well as a Ro-Ro (loading and unloading) station with mooring and fender dolphins. The remaining part of the storage yard will house storage areas and provide space for amenity and administrative buildings that will serve to support logistics processes and those related to the assembly of wind farms.

Dredging works and the main part of the pile-driving works have been completed at the construction site, and the land reclamation works are in the key phase of implementation. – Every day, we deliver 20,000 to 30,000 m³ of backfill material from marine, land and inland sources to the investment site. We use the most modern equipment to carry out the work. At the current stage, the progress of the land reclamation works is 80%, which requires precise planning and coordination of the works, says Zuzanna Matuszewska, Hydraulic Engineering Works Manager at NDI Group.

In the coming weeks, the remaining sheet pile wall profiles of the temporary quay are planned to be driven into the ground, which will result in the closure of the terminal perimeter and will prevent navigation inside it. The final stage of the land reclamation process will involve backfilling the terminal from land sources and land reclamation from behind the sheet pile wall, from the outside, which will mark the completion of the entire process.

The installation of all toggle anchors has also been completed, and in parallel, the installation of ground anchors at the temporary quay has begun. The purpose of both toggle and ground anchors is to ensure the stability of the sheet pile wall.

As for soil reinforcement, work has begun on the construction of CFA piles, i.e. continuous flight auger piles. The works are being carried out simultaneously on two jobsites, i.e. at the outbound quay and at the inbound quay. In these locations, working platforms were prepared with lengths of 180 and 130 linear meters, respectively.

The pace of work is high, and implementation is progressing according to schedule. – Work on the construction of CFA piles is progressing very quickly, and we are also intensively preparing to begin reinforced concrete works. We are delivering reinforcing steel and prefabricated elements that will constitute the permanent formwork for the reinforced concrete monolithic cap – adds Aleksandra Smyk-Sidorowicz, Hydraulic Engineering Works Manager at NDI Group. The prefabricated elements will serve as a form for pouring the concrete that will form the upper part of the quay structure. Once the concrete has set, they will remain permanently embedded in its structure, strengthening and stabilizing the cap, which will connect all the elements of the structure into one whole.

The construction facilities have also expanded. Storage areas for reinforcement cages for CFA piles, steel warehouses, warehouses for prefabricated formwork elements and other materials were organized.

The construction of the T5 terminal is being carried out on behalf of Istrana and co-financed from European funds under the KPO programme and by the Polish Development Fund.
