The course of construction of a new home will be far less mysterious to the home buyer if they understand how a home is actually built. The principles of building a home or any other structure are fairly simple. Basically, walls and floors must be plumb and level. However, simple doesn't necessarily translate into easy.
The person who's having a house built should not only expect to pay more money than they think they will, but they should expect a mess and a mess that's going to last for some months. Dozens of people, delivery trucks, cement trucks and other sorts of vehicles are going to be in and out. The space that the home buyer envisioned as a gorgeous lawn or garden is going to be muddy and filled with junk. Things are going to get lost and things are going to arrive in a damaged state and need to be replaced. Some aspect of the home won't pass inspection and will have to be started over. One of the contractors is going to be surly and uncooperative, at least for a time.
Here is the basic course of construction.
After the house has been planned and a blueprint has been made and the municipality has approved it and every other thing that needs to be approved, after contracts have been signed and a site has been chosen, graded and prepared, construction can begin.
First the foundation is built. This is what the home will sit on and can be the basement, or a crawl space. Sometimes a building can be built on slab of concrete. After this the framing is installed. The first part of the framing is the floor. Then, the walls are built. Walls are usually built on the floor, then hoisted into place. The places for windows and doors are roughed out. Then, the roof is built on top of the structure. The roof can be quite complicated, with trusses, joists and beams. The roof is covered with roofing paper, then covered with shingles. After this the siding is placed on the home to provide for more insulation. Siding can be anything from wood to aluminum to polyvinyl chloride.
After this the house is roughly wired for electricity and plumbing. Though building codes can be complicated, plumbing and electricity codes are probably more complicated than usual, largely due to safety issues. Bathtubs are usually brought in before any other plumbing fixture, as they're so big that it would be hard to get them in through finished doorways or windows. Then, the heating, ventilation and air condition systems, if they're central HVAC, are roughed in. After this insulation is installed behind the walls and between the floors, to be covered with drywall. Some insulation is sprayed or fluffy insulation is tucked between the studs in the walls or the eaves in the roof. Insulation can be made of anything from soybeans to recycled glass. Some of the best insulation was asbestos, but since it proved to be hazardous it's no longer used.
After this the underlayment, or subflooring, is installed and the house is painted. The electrical system is finished and the cabinets and countertops in the bathroom and kitchen are installed.
The plumbing and the flooring, whether hardwood, resilient or carpeting, is installed in the rooms. The HVAC system is finished and the water is hooked up, either to the house's private well or to the municipal water supply. Then, the house's plumbing ฝากขายอาคารพาณิชย์ is connected to the septic system or to a municipal sewer system.
Usually, when one phase of the construction is completed a professional inspector will come in and inspect the work to make sure that it conforms to building codes. If it doesn't it will need to be redone until it's in compliance. The next phase of the construction of the home can't proceed unless the previous phase has passed inspection.
After everything seems to be finished, the contractor will go around the house with a punch list and note down any problems. If there are problems any subcontractors will need to return to fix them before the inspector does the final inspection and deems the house fit to move into.
