Shopping center Puuvilla is founded on piles. The frame is built with reinforced concrete pillars, hollow-core and cast-in-place slabs and pre-stressed concrete beams, with interconnecting steel pillars and beams on the Kutomo end.
Structural design and precast detailing is done by modeling and steel roof structures and facade elements are modeled with Tekla.
Architectural, MEP, electricity, and sprinkler design is done by modeling and the existing structures are laser scanned and an inventory model is created.
Special feature in this project is the very tight element erection schedule and combining new and preserved structures.
The team experiences several challenges.
- Great number of project parties
- Large project
- Tight schedule
- Structural combining of new and old structures, nearness of the river Kokemäenjoki and ground circumstances.
- Phasing planning, design and modeling, delivery of initial information
- Large size of models
- Model upgrading frequency
The frame phase is nearing its end and the project has progressed according to plans. Element installations have progressed at record speed considering the size of the project and the planned schedule. This has been made possible by BIM, design by modeling and flawless design and detailing. Models by other disciplines have been utilized in design and MEP installations have started.
In regard to future projects and development it is certainly essential to plan the design phasing to better support BIM. This development is mainly focusing on the process and not necessarily on the technical tools. The current BIM tools make efficient process possible, but design by modeling needs more initial information than traditional design. This is exceptionally challenging in premises projects where essential decisions from design point of view may stay open until very late in the project.
