The Lime Street project is located in the center of Dublin, close to the River Liffey. The entire project involves the construction of two blocks(East Block and West Block) with 217 residential apartments, recreational rooms on the ground floor and a commercial space on the street level.

Our office was responsible for the preparation of the model, assembly and production drawings for the prefabricated part of both blocks. Originally, the building was designed as a masonry structure combined with concrete poured on the site. The contractor finally decided to use prefabricated elements as the main structure of the buildings, therefore the blocks had to be adapted to this type of solution. This posed quite a challenge for the entire project team involved in the project, and finally resulted in the use of mixed construction on the lower levels. Some of the walls and slabs had to be made of concrete poured at the construction site to provide support for prefabricated walls and columns. On the upper floors, due to the limitations in the usable floor space of the apartments, the external walls were made of a light steel structure in combination with prefabricated elements where it was required for construction reasons.

The prefabricated walls are made as full panels with a thickness of 200 mm and 150 mm, while the ceiling slab consists of full prestressed slabs with a thickness of 100 mm and 150 mm of concrete topping.

Thanks to the use of BIM technology, we were able to efficiently solve design problems by participating in coordination meetings and sharing our 3d model with other industries. In addition, we were able to quickly provide accurate bill of materials and quantity lists.
