The quality inspector must check the quality in question, and can't flow on the surface. Experienced quality inspectors have some key points in their hearts, which will get twice the result with half the effort.

A, construction engineering

1. The plastering of basement, fire stairs and pipeline wells is rough;

2. The floor drain is improperly installed, and some are not in the center of the floor tile or block; Some are located at the joint of two floor tiles or blocks;

3. Mixed wall tile flat joint and concave joint; Due to improper brick arrangement, some main facades appear broken bricks;

4. The basement concrete floor or outdoor aproll has too wide cracks or uneven edges;

5. The edge of the door window frame (or curtain wall) is roughly glued, the glue joint is too wide, or the edge is uneven;

6. The notch of the wooden door hardware installation is too large or too deep, and the edge is not neat. Some notches are inconsistent with hinges, and some door lock boxes are not aligned with door edges;

7. The painting process is not in place, the feel is poor, some parts are obviously drooping, and the upper part of the door leaf leaks;

8. The color difference of granite (marble) ground is obvious, and some have been polished twice at the joints;

9. The ceiling is slightly cracked;

10. Two-color materials (especially paint) on the wall are not well intersected, and some painted walls are cross-polluted;

1 1. The indoor footstool is cracked, damaged or lost (this situation is mostly caused after delivery);

12. The top of the skirting line is not straight, the wall thickness varies, and the top is polluted;

13. The arc line of the external wall is a broken line;

14. The slab joint between the floor block and the skirting block does not correspond;

15. The joints of bathroom tiles are not in place, and some non-integral bricks with a width less than 1/2 are used;

16. The facing layer of the roof parapet is rough, cracked and empty.

Second, the pipeline and equipment installation project

1. Pipeline medium and flow direction are not marked, and valve switch direction is not marked;

2. The screw hole of the pipeline bracket is opened by gas welding, and the periphery is rough;

3. The turnbuckles of the exposed anchor bolts of the equipment installation nuts are too long, some of which are as long as 70 mm.

4. The pipes on the walls and floors are also blocked or blocked loosely; Some even don't directly bury the pipe into the wall, and some have wall sleeves, but the diameter is too large or too small; Some sleeves across the floor are too long or too short;

5. The tuyere of the ventilation pipe is not installed straight;

6. Install power equipment without flexible joints, damping pads and other sound insulation devices;

7. The installation position of sanitary ware is not accurate, the urinals on the same wall have different heights, and some sanitary ware steel frames are not painted with top paint;

8. The manufacturing and installation of insulation protective shell of ventilation pipeline is rough, and the surface is uneven and not straight;

9. The flexible joint of air duct is uneven;

10. The pipeline identification in the pipeline well is unclear;

1 1. Pipe support is not vertical;

12. Imperfect anticorrosion construction, etc.

Three, electrical facilities installation project

1. The length of the metal hose configured in the ceiling is too long, some of which exceed 1.2m, and some even exceed 2.0m.

2. The grounding trunk line is not marked with two colors (green and yellow);

3. The bridge is not grounded;

4. The zero line of the socket is wrongly connected, and the gap between the socket box and the wall is large;

5. The cable tray is grounded at one point, and the fire seal between the inner layers is lax;

6. The grounding branch line in the switchboard is not connected with the grounding main line;

7. The color code of the electric grounding wire does not conform to the specifications;

8. The installation of electrical exposed piping is not straight, and the spacing of fixed points is not in conformity with the specifications;

9. Incomplete identification of cables in the computer room;

10. Hose laying along the wall in the electrical shaft:

1 1. Inconsistent installation elevation of switch sockets, etc.
