Proven by achivements from around the world, systemic formworks allow us rapid contruction of reinforced concrete structures. We selected formwork systems from Doka's range for walls, columns and slabs in the manual. We collected and presented different methods for determining value of the maximum fresh concrete pressure on formwork. We demonstrated a procedure with diagrams for determination of the maximum fresh concrete pressure on formwork. An approach for dimensioning systemic formworks based on previously calculated fresh concrete pressures was presented. A software plug-in for calculation of maximum fresh concrete pressure was designed within the assignment. Plug-in enables its user an automatic calculation of maximum fresh concrete pressure value. It is based on two different methods of pressure calculation for horizontal pressures and one method for vertical pressures on slab formwork. With this manual we gathered informations for systemic formwork design in one place.
