A 14-turbine onshore farm had weathered rock at three positions and soft alluvium at four. A single worst-case foundation design repeated 14 times would have added significant unnecessary concrete and cost.
Ground model built per position from the site investigation rather than a single site-wide characterisation
Geotechnical parameters derived position by position with the interpretation documented
Gravity base at nine positions, piled at five — each selection justified against the turbine stiffness requirement
Rotational stiffness checked against the supplier envelope at every position, which is where over-optimisation usually fails
Design basis table per position so the lender's engineer could audit each decision
A 7-storey 1970s office block had to stay occupied through a seismic retrofit. The original drawings were incomplete, concrete strength varied by 40% between cores, and the client could not vacate more than one floor at a time.
A die-cast aluminium pump housing was 22% over its mass target but the tool was already cut. A new tool would have cost the programme five months.
A 42 MWp plant's provisional connection offer carried a reactive capability condition the originally specified inverters could not meet across the full voltage range. The issue surfaced three weeks before financial close.
