Six trial pits and 12 probe holes showed what the building sits on.
Foundations exposed
The structural engineer had the findings a week after site work.
Report in a week
01
The uncertainty
The structural engineer needed reliable, site-specific information on existing foundations to plan the redevelopment.
02
What we established
Foundation geometry and condition were captured at every location, including defects, construction joints and historic repairs.
03
What changed
The factual report was delivered within one week of completing the works, giving the structural engineer reliable data for the design.
04
How we got there
- Scanned all exploratory locations with CAT and Genny
- 6 manually dug trial pits to 1.30 m below ground level
- 12 probe holes to 0.80 m below ground level
- Recorded foundation type, depth, dimensions and condition, plus drainage runs, ducts and buried structures
- Sketched each pit and tagged locations on plan for the structural model
