In this particular location, engineered foundations were deemed necessary, specifically utilizing mini-piles with a ring beam. This choice was made to accommodate the soil type and mitigate the effects of ground heave, necessitating the use of permanent formwork. It is important to note that such engineered foundations can be significantly more costly, often three times the price of a standard strip foundation.
The design of the new support steels was carefully considered, taking into account the interior design of the space. The columns were strategically positioned to create visual interest from the opening glazing line or to be discreetly integrated within cabinet positions as cased columns.
The steel design was thoughtfully fabricated, ensuring that bolt heads were sometimes recessed to accommodate the interior finishes and appropriate finishing widths.
To enhance structural stability, a “sleeper beam” was incorporated within the concrete at foundation level. Throughout the construction process, periodic inspections were conducted, taking into account key stages of the build, such as achieving wind and watertight status and progressing to the 1st/2nd fix of activities. These inspections ensured the project progressed smoothly and in accordance with the planned phases.
