Laboratory and R&D center building project. It’s a complete architectural package for a multi-story facility, including the ‘Experiment Building’ and ‘Research Center’ blocks. You’ve got floor plans from the ground level up to the roof, showing room layouts, stairwells, and elevtaor cores. There are four main sections (1-1 thru 4-4) showing vertical spans and ceiling heights. It covers drainage specs like DN75 and DN100 pipes plus staircase details for multiple exits. The drawing features curtain walls and fire doors throughout the floor plates. Good reference for institutional or large-scale research projects. 实验楼及研发中心全套建筑施工图。包含平面图、剖面图、立面图、楼梯大样及排水详图。
