1. The company leaders attach importance to it and give it financial, technical and management support.

2. Select the construction team according to the requirements of creating a cup, and require carpenters and masons to have experience in creating a standard.

In the early stage of the project, in order to highlight the characteristics and highlights of excellence, QC team discussed the issue of "improving the construction quality of concrete decorative lines on the fa? ade" many times, and the decorative lines on the exterior wall were made of PC components according to the requirements of design drawings.

The QC team of the project department proposed to change the original design and adopt the cast-in-place construction method in combination with many factors such as construction conditions, time limit requirements, construction difficulty and safety guarantee. Therefore, the project department compared the advantages and disadvantages of three schemes: assembly, structural optimization and secondary structure, and communicated with the technical leaders of the design unit and the construction unit.

According to the six terminal factors, the extended data QC team has worked out a timetable for confirming the main factors. According to the schedule, the QC team consults the construction records, technical documents and monitoring data. Investigate and analyze the terminal factors item by item to determine the main factors.

Design a method to control and recheck the verticality of the whole floor.

1. The engineering excellence measurement team participated in the preparation of the construction scheme of the facade decoration line, and systematically designed the measurement setting-out and the whole floor verticality control measures, which were recognized by the company.

2. Based on the main eight-story structure, through the eight-story axis control line, the decorative lines of 150 are located one by one according to the construction drawing, and the axis position of each decorative line is determined by repeatedly checking the axis of the surrounding structure.

3. Take the axis position of each decorative line on the eighth floor as the reference point, use long steel wire to pull off the line, and use line sag and infrared laser instrument to assist vertical positioning.

4, according to the way of line vertical positioning, passed to a floor, and then determine the axis position of a layer of 150 decorative line step by step, and then check according to the axis control line of a layer, in order to verify the accuracy of vertical positioning of external wall concrete decorative line.

5. After the main structure is completely completed, take the axial position of eight decorative lines as the reference point, pull the lines from bottom to top with long steel wires, and vertically position them with line sag.

6, according to the way of vertical positioning, transmitted to the roof, and then determine the axis position of 150 decorative line on the roof one by one, and then recheck it according to the axis control line of the roof to verify the accuracy of vertical positioning of external wall concrete decorative line.
