In 2005, CLC carried out archaeological excavations at Les Bassins du Nouveau Havre (1500 Ottawa Street) in order to locate the remains of the walls around Basin 4. The area around Basin 4 is made of masonry, except for the entry of the basin, which is made of concrete. Excavations revealed subsequent layers of the walls that include 4 to 6 different components. The composition of these layers corresponds to different time periods in the basin's construction.
