Lijnbaan Rotterdam

Lijnbaan 101–111, originally designed by Krijgsman and Van Duin Architects and completed in 1967, has been renovated several times over the years. In 1998, D&T van Manen Architects carried out a renovation in which two large Octatube curtain-wall facades were added.

Boltt asked Octatube to investigate whether the single glazing in these facades could be replaced with more sustainable alternatives. For Octatube, which is increasingly involved in this kind of sustainability challenge, this formed a relevant part of the project. Octatube subsequently contributed to the engineering. The facade of the left-hand section, designed by Mei architects and planners, was completed in the summer of 2023.

Together with project manager Bouwplot, Boltt developed an action plan to improve the sustainability of the two buildings and merge them into a single retail environment. In a series of short, focused sprints, the existing condition, the documents for the environmental permit application and the construction drawings were worked out in parallel.

Using archival drawings, Boltt incorporated the existing condition into a BIM model, which also formed the basis for the environmental permit application. This integrated model also included Nike’s requirements. The partition walls between the two buildings were removed, a new customer staircase and elevator shaft were introduced, a new storage area was added, and the entrance was moved from Lijnbaan 111 to Lijnbaan 105.

Boltt also prepared the construction drawings for contractor J.P. van Eesteren. PelserHartman first produced a point cloud of the existing condition, which Boltt then processed and integrated into the BIM model together with the suppliers’ models. Boltt also coordinated the process as a whole.
