Self-inspection under DS1140
Self-inspection (egenkontrol) is the check the contractor carries out throughout construction, based on the control points set out in the B2 control plan. It's the day-to-day, practical side of DS1140 - as opposed to independent control, which is carried out by a person who did not carry out the work being checked. We help set up self-inspection so it's documented correctly from day one, and the structural engineer can follow exactly what's been checked.
What self-inspection is
Self-inspection is the check you - as the contractor or the party carrying out the work - perform continuously on site as work progresses. It follows the control points, control types and control levels set out in the B2 control plan, and it forms the basis for the B3 control report.
Self-inspection isn't a formality - it's where most of the actual checking happens, because the people doing the work are best placed to catch an error while it's still cheap to fix.
Self-inspection vs. independent control
Self-inspection is carried out by you. Independent control is carried out by a person who did not carry out the work being checked โ in structural classes 2 and 3 this can be a colleague in the same company โ and the requirement for it increases with the structural class. The two complement each other - self-inspection catches errors as they happen, independent control spot-checks that the self-inspection is reliable.

The most common mistake is that self-inspection gets carried out, but never written down clearly enough to be used in the B3 report - date, who performed it, or the result is missing, or the control point isn't clearly matched to the B2 plan. We set up a simple documentation routine so self-inspection becomes part of the ongoing B3 report, rather than something to reconstruct afterwards.
How KS Danmark helps
We help set up self-inspection based on your B2 plan, train the people doing the work on what needs documenting and how, and make sure the documentation can be used directly in the B3 report without extra work afterwards.

Who carries out self-inspection?
The contractor or the party doing the work, continuously throughout construction.
Is self-inspection a legal requirement?
Yes, as part of the control required under DS1140 and BR18, regardless of structural class.
How does self-inspection connect to the B3 report?
The results of self-inspection are what get documented in the B3 control report.
What does it cost to set up self-inspection?
It depends on the scope of the project. Call us for a concrete quote.
