1. Channel reconstruction acceptance:

First of all, check whether the quality of the materials used meets the requirements of the current national standards. Secondly, check whether the hot and cold water are arranged in place as agreed. Try not to have joints in concealed water supply pipes. If there is a joint, there must be a maintainable inspection port. Water pipes should not be close to the power supply, and the distance between water pipes and gas pipes should not be less than 5 cm.

2. Acceptance of circuit modification:

First of all, check whether the quality of the materials used meets the requirements of the current national standards. The copper core wire with a cross section of not less than 2.5mm2 should be used for electrical wiring, the wiring for laying walls and floors should be concealed, and the conduit must be threaded. PVC conduit must be used in home decoration, and junction box must be equipped at the joint. Secondly, check whether the power supply, switch, telephone line, closed-circuit television line and communication line are arranged in place as agreed, and the wires and telephone lines, closed-circuit television lines and communication lines shall not be installed in the same pipeline.

Note: Three-color wires should be used for power sockets, in which the zero wire is blue and the ground wire is yellow-green, and the distance between wires, switches, sockets and gas pipes should not be less than 15cm.

3, waterproof acceptance:

Check that the turnover height around the waterproof layer in contact with the wall is not less than 30cm, and conduct 24-hour water storage experiment to prevent leakage.

4. Acceptance of wall tiles and floor tiles:

First of all, check whether there are empty drums, skewness, lack of edges and corners, cracks and other phenomena in wall tiles and floor tiles. Secondly, check whether the angle of Yin and Yang is vertical and horizontal-surface flatness is not more than 2mm, verticality is not more than 2mm, joint height is not more than 0.5mm, joint straightness is not more than 2mm, and joint width is not more than1mm..

Matters needing attention: Try to buy better quality wall and floor tiles for construction.

5, wood production part:

Before construction, it is necessary to check whether the on-site materials conform to the contract and meet the requirements of the current national standards. It is best to communicate with the construction party on site before the construction starts, and reconfirm the contents of the construction project to avoid rework and waste.

After the completion of the wooden production part, first check whether the manufactured objects are constructed according to the design requirements, whether the doors, windows, sets and cabinets are straight and firm, and whether the wooden decorative surface should be smooth, uniform in color and without gnawing;

The nail cap is about1mm lower than the plate surface; Windows and doors should be installed with straight openings, flexible switches and no warping, and the opening direction should meet the design requirements. Hardware installation should be complete, and wood screws should be tightened.

The wooden keel of ceiling and partition should be painted with fire retardant paint, and the keel should be straight without deformation; The clearance height between the door leaf and the ground should be controlled at 6 ~10 mm.

6. Coating part:

Before construction, it is necessary to check whether the on-site materials conform to the contract and whether the quality meets the requirements of the current national standards.

After completion, check the surface quality of the coating without peeling, brush leakage, undercoating and sagging, and clean the hardware and glass. Before coating latex paint, check that the plastering layer and the plastering layer and the matrix must be pasted firmly without delamination, hollowing and cracks.

The simplest acceptance method is at the distance of 1.5m from the wall surface, with even front spray points and smooth brush lines. The acceptance of wallpaper is also 1.5 meters away from the wall, with seamless front, seamless internal corner and seamless external corner.

7, mesa stone installation part:

The installation of stone countertops should be completed after the completion of wood work and before the production of paint parts (such as window sills). First, check whether the countertop is flat and firm, and whether the color is uniform. Secondly, check whether the table joints are firmly bonded and the flatness is not more than 200.
