Normally a job like this falls apart into pieces: an engineer for the calculation, a builder for the sawing, a plasterer for the wall, and you directing traffic in between. In a language you may not speak. We turned that around. At De Draagmuurkoning the engineer and the builder sit at the same table, and you have one point of contact.

Contractor and specialist in concrete sawing and drilling, running his own company in the Betuwe since 2019. Jordy and his people prop, saw, set the steel and finish up to and including the plastering. What he promises about the schedule, he delivers on site.

Structural engineer, graduated from Eindhoven University of Technology. Simon calculates every opening to the Eurocode and signs the report that goes to the municipality. The same report the work is literally built on.
When the engineer and the builder do not know each other, time is lost in the handover: the builder waits for the calculation, the engineer has never seen the site, and every question from the municipality puts everyone back around the table. We talk before anything is quoted. That is why the quote matches what actually happens, and why the steel that goes in is the right steel.
We do this work through two companies you can also find separately: MAREE Aanneming for wider building work and Cox Constructieadvies for structural calculations. De Draagmuurkoning is where those two come together for one job: opening up a wall.
MAREE Aanneming B.V. is registered with the Dutch Chamber of Commerce under number 74031937, Cox Constructieadvies under number 86134191. For the complete package MAREE Aanneming is your contracting party and main contractor; Cox Constructieadvies provides the drawings and the structural design.
