At the beginning of April, we started to work inside the shelter R 514. The basic goal for this year was the wall with the entrance defense shooting range in the vestibule of the shelter. Post-war detonations of artillery ammunition damaged the wall, ventilation installations sunk in concrete and completely destroyed the fragment of the wall holding the door frame of explosion-proof bipartite doors. The frame with the bipartite door was torn to shreds and the sluice pushed into the room damaging successive internal walls. The mutilated wall was crushed by a shock wave and pushed on the reinforcement by 5-10 cm into the observer's room. The first works consisted in forging damaged, bent sections of frames, then we systematically proceeded to forge the wall from both sides to a depth of 20 cm. We unveiled the spatial grid of arms, removed, damaged, cracked concrete and salinity. Then in May we proceeded to fit and assemble and a new frame of two-way doors and frames for gas-tight doors. Work with matching the frames and shoeling of damaged walls lasted until August - the hanging frames partly in the air were leveled and welded to the channel for reinforcing the lintel. After the August event, we started to reinforce the defects in the walls and to reinforce the fastenings and floors in their surroundings. In October, we started formwork and concrete works from a small wall near the door of the explosion-proof door from the side of the outer wall and the door hinge. The wall gained solid reinforcement - fixing a new cast to the outer wall of the shelter - it was not originally armed, so the explosion along with the door frame pushed it into the gas lock. Shuttering, buoyancy and flooding were completed on one weekend. The main internal wall of the 514 was already the main purpose of the reinforcement and shuttering works. We started with the installation of the channel bar above the firing range and the repair of the pipe dropping the used air from the object to the vestibule. Due to the large amount of concrete, we decided to reconstruct the concrete wall in stages. The first stage to the lower edge of the firing range, the second to the C-section of the new elevation obtained a strong anchorage to the original wall core. Concrete works absorbed over 2 cubic meters of concrete and took us November and December. The final stage of work in December was the "Offset" of the wall rebuilt from the outside, minor concrete alterations. The culmination of this year's work was the assembly of explosion-proof two-way doors type 434p01 together with gaskets meticulously reconstructed for several years with the frame by Domel. From January we are starting concrete works on the inside of the wall with a firing range in the observer's room together with the reconstruction of the fasteners under the heavy 360kg 422p01 board, and concluding the corner of the walls and the frame separating the crew's room from the observer's room.

The last days of December and in our work the time has come for an observer's room. We made additional strain anchors for the new concrete and formwork to pour the first layer to the height of 0.95m. Earlier, we put the door frames of the gas-tight doors to the crew's room. The next task was to make the graft anchors and formwork on the fragment from the door frame of gas-tight doors and the entire corner, it was necessary to make a slat for wooden paneling with a trapezoidal cross-section and its assembly. The work completed the foundation of the corner formwork and displaced it. We also completed the assembly and fitting works at the 434p01 duplex door.

Further work at the observer's house. We put in the prosthesis of the 422p01 board, we made the formwork and we concreted the wall up to the ceiling, now two weeks of pause while waiting for the concrete to be squeezed.
