Officials and builders, who finished the frame construction of hundreds of dwelling houses and production buildings and their exterior plastering in the first half of this year, promote the interior plastering and roof-tiling, true to the important tasks set forth at the 8th Congress of the Workers' Party of Korea and plenary meetings of the Party Central Committee.

They produced a large amount of building materials by themselves through a movement of collecting idle materials.

They also saved a large quantity of building materials by recycling waste materials and increased the production of building materials with locally available raw materials.

Putting every work process on a mechanized and specialized basis and introducing advanced construction methods, they bring about collective innovations to complete the project ahead of schedule.
