Generally speaking, the hidden cost is intangible, but it has a vital impact on the whole result. The construction technology is not up to standard, and the details are not done well. There will be many problems in the later use, and serious ones will be "reworked" again. The hidden cost here is really a bit high, direct dry goods arrangement! ! !
1, hydropower (for short-term design)
(1) Grooving should be straight, and the thickness of protective mortar layer for later line pipe should be >; Five millimeters.
(2) When the strong and weak branch lines pass through the pipeline, the intersection should be treated to prevent signal interference.
(3) There should be no joint in the conduit, the conduit should not be at right angles at the corner, and the curvature should be large.
2. Waterproof material
(1) carbon slag backfill.
(2) Toilets, open balconies and kitchens need to be waterproof. Conventional kitchens need to be waterproof up to 30cm, moistureproof up to 50cm, and bathrooms need to be 180cm.
(3) Waterproof coating is generally coated with 2-3 layers, and each layer must be thoroughly dried (not sticky) before construction can continue.
(4) After waterproofing, plug the sewer pipe for waterproofing, and do a 48-hour closed water test. No water penetrated into the next room and downstairs, thus completing the closed water test.
3, the ground
(1) Before laying the floor, the floor must be leveled first. When laying floor tiles on uneven ground, there will be empty drums, which will make a crunching sound when stepping on them.
(2) The floor tiles shall be flat, with clear texture and uniform color. The crosshairs shall be horizontal and vertical, the ground shall be paved flat, the flat-fell seam shall be even and straight, and the paint color shall be consistent without scratches.
4. Ceiling (there is no construction drawing for the time being, but a recent design drawing is required)
(1) The bottom of gypsum board ceiling supports the side, and L-shaped corner technology is adopted at the corner to stagger the stress points, thus effectively avoiding cracks in gypsum board joints caused by the gravity of ceiling.
(2) For suspended ceilings with keel spacing less than 35cm, steel expansion screws must be installed for the main keel (light steel keel).
(3) pay attention to the ceiling can't be all wooden keel without deputy keel, wooden keel should be coated with fire retardant coating.
(4) There are many ceiling pipes in the kitchen and bathroom. If gypsum board suspended ceiling is used, it is necessary to reserve a manhole.
5, cabinets
① The quality of cabinets mainly depends on the edge sealing of hardware and plates. Pay attention to the brand, series and model of hardware, and pay attention to the sealing of the edge of the plate.
② Pay attention to protecting the countertop when installing the cabinet.
6. The junction of the interface wall with the ground and the sky is the place that best reflects the quality of the house. The interface shall be smooth and free of burrs.
"Renovation rework" affects the mood, wastes time and energy, and can also be understood as "supervision and guidance" of the owner's friends. You must spend some time on some key nodes ~
