Unlike conventional construction where on-site tolerances can be somewhat accommodated, PEB structures are factory-fabricated to exact dimensions.

The column base plates, girts, and purlins are all manufactured to match specific anchor bolt positions.

If the anchor bolts are even 5–10mm off position, the PEB erection team cannot bolt the structure down correctly — leading to delays, rework, and potentially structural compromise.

Capital Surveyors uses robotic Total Stations with sub-millimetre accuracy to set out PEB foundations to manufacturers’ specifications, and conducts independent verification surveys after bolt casting to confirm positions before the structure arrives on site.
