Alterations Historic Building
Oldbury Place was a complex project converting an existing Victorian industrial building into 3 modern townhouses and incorporating a new two-storey basement. We were required to combine the temporary and permanent works design for the basement and superstructure.
Sequencing
The construction sequence was particularly tight and, to achieve the programme, it was not possible to construct the basement and then the upper floors: they had to be undertaken at the same time. To achieve this Croft designed a top down construction. This is a technique that is used on larger new build office developments. Croft took the technique and developed it to an existing property.
Cost implications
Piles were drilled and into the wet concrete steel plunge columns were inserted. From the plunge columns the ground floor deck was constructed. This allowed the superstructure works to continue while the basement works continued in sequence. This significantly reduced the construction time.
