When wondering how to choose a building level, any person is aware of the consequences of a wrong decision.
A common type of bubble level is its rectangular modification, which is inexpensive.
After all, any, even the smallest deviation from a flat surface can lead to the most deplorable consequences, up to a complete rework of a just completed repair. Therefore, the question of how to choose a building level should be taken with all care, because this tool can be of several different types, the properties, purpose and price of which can vary significantly.
Currently, the market has a fairly wide range of these building tools. One of the most common measuring instruments of this type is the bubble level. It consists of a body and a flask filled with a liquid in which an air bubble floats. This level is very simple and at the same time quite accurate and reliable.
What are the types of levels
The principle of operation of the water level.
Bubble levels. The most common type of this level is its rectangular modification. Its length varies widely and can be 2.5 meters. The minimum size is 20 cm. However, occasionally you can find devices of a telescopic design, the length of which reaches 4 meters. Their flasks are made of impact resistant transparent material. Alcohol is used as a filler.
Some of these tools are equipped with magnets, which makes them much easier to use on steel surfaces. There is also a variety of levels that are used when working with pipes: such tools are usually small in size and have a semicircular recess running along the body. Thanks to it, the device is well kept on the surface of the pipe. These tools have a low price, but versatility is not their strong point, so it is better to choose a different type of level.
water levels. This type of measuring instrument, otherwise known as a hydraulic level, is well suited for measuring the deviations of large horizontal surfaces. It consists of two containers filled with liquid, which are connected by a hose. The main feature of these levels is that their length ranges from 5 to 25 meters, which makes them indispensable when working with extended surfaces and at the same time absolutely useless for use in an apartment.
The principle of operation of the laser level.
They are sensitive to heat, so keep them away from heat sources. You also need to ensure that no air bubbles enter the water when filling the containers, as this significantly affects the readings of this measuring device.
laser levels. Measuring devices of this type are among the most accurate and at the same time the most expensive. Their main advantages are small size and large range, which can reach several tens of meters. They are also best suited for measuring large and extended surfaces, as laser ray, emitted by this tool, can unfold into a plane. In addition, they show themselves perfectly when laying directions. For ease of use, such measuring instruments are equipped with tripods and magnetic suction cups.
Top tools have not one laser beam, but several. They can intersect with each other, facilitating and refining measurements.
This device can definitely be called the best among all levels. It is versatile, accurate, compact and practical. It has only one drawback: its high price.
Choosing a level in the store: what to look for
The type of measuring device largely depends on how large-scale tasks will be solved with it. After all, it is one thing when the level is chosen for frequent use in large-scale construction work, and quite another when it is needed only to level the floor in the apartment.
There is no need to fall under the influence of products of well-known brands and choose the most famous brand, because the main thing in any thing is its quality, and this indicator often has nothing to do with a big name.
How to choose a bubble type building level
Diagram of a bubble level.
First of all, you need to decide for which tasks you need this measuring tool. If you are going to level the walls with it, then you need to choose the maximum length level, but if the question is posed much more modestly and you just need to attach a bookshelf, then the tool, accordingly, should also be smaller.
The air bubble itself should be clearly visible, and the marks on the level flask should be black and there should be several of them. These marks should be very close to each other, forming a kind of scale.
After this verification step, you can proceed to the next one and test the accuracy of the device. If the purchase is made in a specialized store, then for sure he has special stands that are specifically designed to test such measuring instruments.
For the test, the device should be placed horizontally and accurately remember the location of the air bubble on the flask scale, then turn the level 180 degrees. If everything is in order with the device, then the bubble will not change its position relative to the scale.
After that, you need to check its work in vertical plane. For this, an appropriate stand is selected, to which the device is applied. Further, everything happens, as in the previous case: the location of the bubble is remembered, then a 180-degree turn follows. If the bubble remains in its place in this case, it means that the level is made with high quality and you can safely buy it.
In the absence of such a stand in the store, upon arrival home, you need to invite a person who has a level or a laser level and use these tools to check the correct operation of the purchased one. If something does not suit you, then there is always the opportunity to return the purchased device back to the store.
What to look for when buying a laser level?
If you have made a choice in favor of a laser measuring device, then when buying, first of all, you should pay attention to its technical characteristics, the main of which are measurement error and range. The accuracy of the laser level must be at least 3 mm for every 10 meters, and the range must be at least 20 meters.
Often, this device comes with special glasses that allow you to better see the laser beam.
In addition, these devices are equipped with two types of lasers, which differ in the color of the beam they emit. Red emitters are the most common, but if possible, it is better to choose an instrument with a green beam, since this color is more visible and contrasting to the human eye. However, levels with a green laser are somewhat more expensive than their "red" counterparts.
It is worth taking a closer look at what is included in the package of the device.
Often it is very diverse and includes both many useful items and those that you can do without.
If, along with the purchase of a laser level, you are going to purchase some kind of addition to it, then be sure to consult on this with sellers or friends who understand such things so that it does not happen that the purchased accessory does not fit your type of device.
Buying a level is a very important step, on which the quality of the upcoming repair directly depends.

How to choose a building level? And which one is better?
The final result of the work of a number of industrial specialists depends on the accuracy of measuring instruments: a builder, a bricklayer, a carpenter, etc. The building level of various modifications is a simple but indispensable tool for any serious team or individual craftsman, which allows you to determine the accuracy of the location of horizontal and vertical surfaces. The history of the appearance of the first spirit level dates back to the second half of the 17th century, and the vertical plumb line is a well-known primitive prototype of later inventions.
The generally accepted classification for building levels:
- Bubble (water level) - with flasks installed in a rigid case filled with liquid, and the presence of a floating air bubble in each flask;
- Laser level - with fast and clear marking by a point of a laser beam of working surfaces;
- Water level (hydrolevel) - the principle of operation is based on Pascal's hydrostatic law and checks the compliance of the planes of horizontal surfaces.
Despite all the clear innovative advantages of the same laser level, skilled craftsmen never refuse to use a quality bubble level - this versatile tool that has stood the test of time.
The main characteristics of the building level
- Measurement accuracy (from 0.3 mm / m, the longer the building level and the heavier it is, the higher the accuracy of its readings);
- Impact resistance. As a rule, levels have a hollow body, but with walls of sufficient thickness;
- Wide resistance to the slightest bending and torsion;
- Measuring flasks with a high degree of transparency and resistance to discoloration, haze, cracking and leakage when exposed to low and high temperatures, as well as ultraviolet rays.
Device
A rigid monolithic, most often rectangular case with a milled bottom edge is made of light and durable materials (aluminum, polystyrene, plastic, wood) with an anti-corrosion coating. In the case, depending on the required accuracy, a certain number of transparent sealed glass flasks (level eyes) are securely fixed with an air bubble floating in a colored alcohol-containing liquid:
- one flask - only for a horizontal guide (180 degrees);
- two - for horizontal (180 degrees) and vertical guides (90 degrees);
- three - for more complex work, with an additional third camera that controls the measurement of the angle of inclination (rigidly fixed at 45 degrees, or swivel - to measure any angle of the controlled surface).
In order to minimize errors in angular vision, limiting lines - risks - are applied on the surface of the measuring flasks. Eyes for checking the position of surfaces of the vertical plane and the angle of inclination have built-in mirror reflectors for simultaneous control of the position of the bubbles.
Plastic plugs at the ends of the level protect the structure in case of accidental drops.
Some level manufacturers provide and additional amenities: for example, a built-in magnifying lens for more comfortable eye control of the bubble, magnetic systems or fluorescent flask liquid for the possibility of continuing work even in the dark.
The principle of operation of the bubble building level is simple: measuring and adjusting surfaces relative to the horizontal and vertical planes occurs by moving the bubble inside a certain level eye. The result of the correct adjustment will be the presence of the bubble exactly in the middle between the measuring marks of the flask.
Building level. Which is better?
Having decided to purchase a building level, it will not be superfluous to familiarize yourself with some recommendations for choosing it:
- Flask - must be securely fastened in the body. When buying, it is worth abandoning the level at which the flask is screwed with screws, because of which it can become loose over time. Flasks made of polyacrylic should be chosen, which is stronger than glass and more transparent than plastic.
- Level length - it is necessary to take into account the type of work to be done, since the larger the working area, the longer the level should be chosen;
- Defects - the building level is a measuring device, so when buying a tool, you must make sure that there are no factory defects, as well as errors in the readings.
- Case material - the tool can be made of plastic, metal or wood. The most reliable and durable is, of course, the metal level, inside which there are stiffeners
- Markup - the best option is to place control strips inside the bubble itself. The divisions applied to the surface of the flask should be clear and located close to each other.
The run-up in the cost of building levels is quite diverse. At the same time, it is not worth asking for a choice of more economic models, especially if you need to use the tool repeatedly. If you have to carry out a thorough repair, then experts strongly recommend purchasing a professional tool. For him, a characteristic difference is the presence of a shock-resistant case with special rubber pads, which, during operation, are able to soften the blows from falls, etc.
In operation, it is better than others, the construction level of the famous German brand "Stabila" has proven itself. For such a tool, on average, you will have to pay from 700 to 1800 rubles. This measuring device is famous for such advantages as:
- high-quality and stable reading of indications (high degree of measurement accuracy);
- good ergonomic characteristics;
- precision in the geometry of the aluminum profile housing.
In addition, this brand also produces magnetic building levels, which make it possible to work with electricity, and are equipped with special slots for marking switches and sockets.
In addition to "Stabila", another good option could be the building level of the company "Shark". The levels of this brand are good because they are not afraid of falls and bumps. Also, good models are produced by Ermak, Bosch or Kapro. For example, the Kapro company constantly updates its models and often introduces the latest innovative solutions, releasing tools for household and professional type. The models of the German company Bosch are distinguished by high quality. A similar tool with Bosch models is also produced by the Russian company Condtrol, which is more affordable.
In the middle category of such instruments, it is worth highlighting the levels produced by Matrix, Brigadier and Stayer, which are distinguished by their high measurement accuracy and optimal cost-to-quality ratio.
However, when buying a building level, a well-known brand should not be a decisive aspect. The main thing is to decide on the type of future work and the frequency of using the tool.
180 degree method
You can check the accuracy of the level in the simplest way, called the 180 degree method:
- It is necessary to put the building level tightly, without gaps, on a flat horizontal surface and remember the position of the bubble relative to the marks.
- In the horizontal plane, turn the level 180 degrees and place it clearly on the same area.
- In a qualitative and accurate level, the position of the bubble should remain the same.
In the same way, you can check the accuracy of the vertical readings.
Round bubble level
This kind of building levels is designed to control only horizontal surfaces and differs somewhat from the usual levels in the design of the body with the same principle of operation. The round level is a sealed hemispherical capsule made of impact-resistant glass with a fixed flask, inside which the position of the bubble is determined by a bounding round line.
The scope of the round bubble level is not only construction work and control of the degree of shrinkage of already rebuilt buildings. Such levels are widely used in photo and video shooting for strict adjustment of the horizontal position of the equipment tripod. The use of round levels is also very common when installing trade or control scales, as well as for constantly monitoring the stable horizontal position of stationary machines, industrial tools and even jewelry surfaces - for example, polishing wheels.
A round bubble level often has the possibility of local attachment to a controlled surface and a very low cost with high measurement accuracy. A knowledgeable person will appreciate this simple and essential tool.
The ubiquity of levels
Whatever work you have to do (check the vertical and horizontal alignment of the surface of the walls, floor and ceiling; install the washing machine without distortions, hang bookshelf or a picture) - the simplicity and ease of use of the bubble building level will help you do it quickly and with the highest quality. Even in the presence of a laser level or a plane builder that is more complex in execution and principle of operation, the building level, unchanged in the arsenal of any master, will not remain idle.
proinstrumentinfo.ru
The bubble level is an indispensable tool in construction. With it, you can check the slope and angles, create perfectly straight lines in any plane. Levels are also used when laying pipes, when installing household appliances, vibrating during operation and demanding on the evenness of the base. Such devices should be in the arsenal of any home master, we will talk about their design and selection rules in this article.
Design - features of modern building levels
Bubble level construction is a structurally simple tool. It is a plank of solid material, which contains several ampoules filled with liquid and some air. Measuring marks are applied on the surface of the ampoules, which make it possible to determine the evenness of the measured surface by the position of the bubble. To measure tilted surfaces, you can use the indicators of air deflection relative to the central marks on the ampoules.
Ampoules with air are the most important parts of any level, if the integrity of the ampoule is broken, the device cannot be used. Technical alcohol is usually used to fill ampoules. To increase the functionality of the instruments, some manufacturers add other details to the bar, such as lenses, which allow you to better see the bubble. To ensure the ability to operate the level in conditions of insufficient lighting, fluorescent components are added to technical alcohol, thanks to which the liquid ampoules will be clearly visible even at night.
You can also find shockproof models of measuring instruments on the market. During construction, devices are constantly exposed to adverse effects: they are strongly shaken, dropped, which ultimately leads to damage and failure. Long levels are most susceptible to adverse effects, during the fall of which the impact force is significantly greater than that of brands with a short frame. Anti-impact tools are much more expensive than others, but they are more reliable and usually last much longer than cheaper counterparts.
The durability and quality of the measuring device is also affected by its base - a frame consisting of aluminum, wooden or plastic strips. Levels with aluminum bases are the most common, they are made of hollow planks and are very light in weight. However, this is the main disadvantage of such tools. The heavier the device, the better its technical characteristics, the more convenient it is to work with it and the easier it is to obtain accurate measurement results.
There are quite specialized models of such devices. For example, to work with metal bases, it is easiest to use special levels equipped with magnets. They can be attached to the base and easily obtain information about the evenness of the surface. A ruler on the long side of the level can also be a useful addition, it will be needed when, in addition to the evenness of the base, other measurements need to be taken.
The simplest models are equipped with only one vial with an air bubble, but today they are considered very outdated and are rarely found in stores. It is much more convenient to use levels equipped with 2-3 containers. In such devices, one ampoule is located on the long, wide side of the bar; it is designed to measure horizontal planes. The second ampoule is placed on the narrow side of the level perpendicular to the first, it is needed for convenient measurement of vertical surfaces. The third flask is placed on a narrow reverse side strips at an angle of 45 degrees, its main purpose is to control the operation of the device.
Bubble levels can be of different lengths. The simplest modifications for home use have a length of 20 cm, while professional devices can reach a length of 300-400 cm. The functionality and efficiency of the level directly depend on the length. In a private house, a short level is sufficient for the installation of household equipment and simple installation work. For laying tiles, longer strips are required, within 40-100 cm. The longest levels are used when performing complex construction and installation work. IN household they are rarely needed.
Learning to choose measuring devices - what to look for?
The construction market presents spirit levels (levels) in the widest range. Such devices are perhaps the favorites of manufacturers of low-quality and fake products, because every owner wants to have such a device at hand, but not everyone knows how to choose among the assortment of a hardware store. The spirit level is quite simple to manufacture, but requires the highest precision and the use of only high-quality materials.
Fake and simply low-quality levels are produced in violation of all possible technologies, they are used to create unreliable materials that are not capable of providing decent resistance to external influences and durability for the device. If you are not familiar with measuring instruments, you should only buy products from reputable manufacturers. The following brands have proven themselves well:
- Bosch;
- Kapro;
- Gross Laser;
- Stabila;
- Shark;
- Leader;
- Yermak.
You should not choose equipment only by cost, keep in mind that devices from these manufacturers are not the cheapest on the market. If you see a Bosch spirit level at a ridiculous price, it’s most likely that you have a fake in front of you, and you shouldn’t buy it.
In addition, you need to choose devices that are fully consistent with the planned work. If you are planning to tile the floor or walls yourself, you need a good household level. No need to buy a very expensive professional spirit level, you will just waste your money. First you need to decide on the length the right tool. The more complex work you have to do, the longer the spirit level you need. The optimal size of the household level, which can be used to solve various problems, is 40-60 cm.
When choosing, carefully examine the device visually, paying attention Special attention glass elements. The flasks must be intact, without any signs of mechanical damage and impacts. Then you need to evaluate the strength of fixation of ampoules with bubbles on a long bar. The containers should be installed as tightly as possible, they should not stagger and fall off.
On the shelves of hardware stores you can find levels in which the flasks can be adjusted. This is an ambiguous function of measuring devices. On the one hand, due to the adjustment, you can reconfigure the damaged level, on the other hand, the device will be much more vulnerable to adverse mechanical effects, drops and shakes. We highly recommend purchasing spirit levels with a tight fixation of ampoules, they are the most reliable and durable.
After studying the integrity and reliability of the fixation of the ampoules, pay attention to the air in the containers and the marks applied to them. All marks on the flasks should be clearly visible and located in close proximity to each other.
It is best if the control bands on the ampoules are located inside the flasks, and not outside, because due to active use devices from the outer surface of the tag can simply be erased.
Regardless of what material the spirit level itself is made of, the device must be heavy, durable and stable. It is best to choose devices equipped with additional stiffeners. You can also choose from among famous models, which you like visually, but external attractiveness does not affect the accuracy of measurements.
It is highly advisable to pre-check the performance of the level before buying. In large construction stores for this purpose there are special stands with a perfectly flat surface. If there is no such stand, you can simply place the level in a horizontal plane and remember the position of the air bubble. After that, the device is rotated 180 degrees and placed on the same surface, in both cases the vial in the ampoule should be in the same position. If there are no deviations in the measurements, the device is working properly and you can buy it.
By the way, even if you do not check the accuracy of measuring flat surfaces with a spirit level in the store, you can do it at home. But be sure to keep the receipt from the purchase, so that in case of problems with the level, it can be replaced with another one. However, experts do not recommend buying measuring equipment, whether it be a bubble spirit level, or a level without preliminary checks. Even the most expensive devices from well-known manufacturers need to be checked quality equipment may have a marriage and fail during transportation from the manufacturer to the place of sale.
Setting up unfixed spirit level containers
If you purchase a model of the measuring device with loose ampoules, it can be adjusted and reconfigured if readings go astray. Setting up the device is quite simple, you can easily cope with such a task yourself. To do this, you need to determine the most even wall in the room. If you have not previously checked surfaces with an accurate spirit level, you can choose the visually most even wall.
Step back from the left corner of the wall about 4 cm and drive a nail into the surface at eye level (you can screw in a self-tapping screw) so that the fastener protrudes on the surface at a distance of 20-30 mm. From above, the spirit level is positioned in such a way that with one side it rests on a screw or nail, and with the long side it lies against the surface of the wall. Adjust the instrument so that the air in the container indicates flat surface. Draw a line along the edge of the level on the wall.
Then turn the device over and repeat the procedure again. If the drawn lines completely coincide, then the device is adjusted normally and can be operated. If the marks diverge, then you will have to additionally configure the device. To do this, on the right side of the wall, where the marks end, a central point is marked between them. The level is laid on the nail so that with one of its edges it is adjacent to the marked point. In this position, the device must be fixed and the ampoule adjusted so that the vial shows an even base.
A good tool is a great help in any job, and a good building level is necessary in any household (hang a mirror or a locker), when repairing. And for the construction of a bath you will need at least two or three different levels. There are quite a few types of this tool and each has its own characteristics.
Bubble levels are the most popular. Most likely, this is due to their not very high price and sufficient measurement accuracy. These instruments come in very different lengths - from a few tens of centimeters to 3 meters. During construction or repair, levels of several sizes are usually needed: short ones are convenient if you need to check the compliance of small areas, and long ones are indispensable, for example, when plastering works, when installing the crate for lining in the bath, etc.
Bubble levels have one, two or three transparent chambers with a scale filled with liquid with a bubble. The position of the bubble relative to the applied divisions determines the deviation from the vertical and horizontal. If the tool has only one camera, only horizontal surfaces can be controlled, if there are two cameras, vertical and horizontal. There are levels with three flasks. The third, if fixed, serves to determine the deviation from an angle of 45 degrees. But there are models with movable flasks that allow you to determine the deviation from the selected angle of inclination. These will be needed during the construction truss system and some other works.
There are several modifications of bubble levels: some of them have built-in magnets and it is convenient to fix them on metal surfaces. Such levels are also called magnetic levels. There are special tools for masons and tilers: there are places where you can hit with a hammer, which is very convenient.
How to choose a bubble level
The range of prices for these tools is quite large. Definitely, it is hardly worth buying the cheapest ones, unless you need them for one-time work. If you have construction or major repairs coming up, you should choose one of the professional levels. Although they cost several times more, they will also serve much longer: they have thick-walled cases for which bumps and falls are not so terrible, some are equipped with rubber pads that soften the blows. The building level stabila proved to be the best. Not bad is the Kapro tool (the manufacturer gives a lifetime warranty on flasks) and Kraftool. These are probably the best building levels available on the market today. If we talk about the middle price category, then Zubr, Stayer and Matrix have proven themselves well.
When choosing a tool, pay attention to the fastening of the flasks: they shouldn't wobble. It is better if they are mounted tightly, without screws. At first glance, the flasks reinforced with screws are good because they can be adjusted independently, but in practice such tools go astray very quickly, and you have to repeat the entire setup procedure again and again. In order to work with the level it was convenient, you must clearly see the flask, the divisions on it and the position of the bubble. The farther apart the stripes on the flask are, the more difficult it is to determine how displaced the bubble is.
Important! Even after a slight drop, the bubble level may begin to "lie", especially for cheap models. For this reason, check the level for accuracy right in the store.
How to check the bubble level
To check the accuracy of the level, you need to put it on any horizontal surface (for example, on a shop window), note the place where it lies, and remember the position of the bubble. Rotate the tool 180 degrees (the part that was on the right should be on the left), set it in the same place and look at the position of the bubble again. If the readings match, the horizontal bulb is set correctly. Repeat the same test on a vertical plane (for example, on a wall). If the readings match there, you can buy this level. If there are deviations somewhere, ask for another one.
For details on checking the bubble level, see the video.
Laser building level
Laser building levels are the most modern and accurate, but also the most expensive. The most budget options cost the same (or more) as professional bubble levels. But it's a compact device that attaches to any surface and has a range of up to 100 meters. Laser levels allow you to perfectly set a straight line, some models have the function of scanning the direction in a plane, there are cross models with 2 or more (up to 10) lines, with which you can perform any work. Their only drawback is their high price.
The world leader in the production of laser levels is the German company Bosch - it produces a huge line of laser levels. Compact models include the Bosch PPL5 model.
This device is quite compact, as you can see by watching the video.
The laser level can be mounted on the wall, and along the guide to glue the tiles on the walls in the bath or sauna.
If you are not a professional builder, there is no need to buy expensive levels, which include Bosch products. If you need laser level only for the construction of a single bath, it is quite possible to buy a laser level in China. The price of this level on eBay is only 8-9 dollars, and delivery to Russia is free.

The laser requires three coin-cell batteries to operate. Water or hydro level
This tool is suitable for determining the presence of deviations of horizontal surfaces. Neither verticals nor planes located at an angle can be checked by them. The water level is a set of a hose (from 5 to 25 meters long) and two glass flasks with a scale printed on them.
Water is poured into this design (be sure to fill in water at room temperature and make sure that bubbles do not form). You can draw a horizontal line by setting the same water levels in both flasks.
Water levels are useful when working with large surfaces (for example, when laying foundations or piles), but they are inconvenient when working in small spaces. Their main drawback: sensitivity to temperature changes: it is impossible to check surfaces located at a distance of less than 1.5 meters from heaters or other heat sources.
The great advantage of water levels is that when correct use, you can ideally die out the horizontal on large planes. For this reason, for marking, it is advisable to use the water level, and not the bubble level.
When buying a hydraulic level, check that there are no cracks on the plastic flasks.
Pipe levels
They work on the principle of bubble ones, but they are small and most often made in the form of a rectangle. Some models are foldable.
They are useful when working with pipes or when laying profiles (some have appropriate holes and / or magnets to make them easier to attach).
There are many types of levels and their various modifications. The main thing is to determine for what purposes you will use them, and choose the most suitable option for them.
Level on Android
What progress has come to ... This is what I want to say when you find out that now you can download and install the building level program on a device running the Android operating system (Android).
The building level program in a smartphone A fairly large number of such programs have already been created, but there are not as many high-quality ones as you would like. One of the most popular levels for a smartphone is the program bubble level, which can be installed by following this link https://play.google.com/store/apps/details?id=net.androgames.level&hl=en .
The Bubble level program allows you to switch the level view.
The Bubble level program allows you to switch the level view The smartphone is oriented in space with the built-in camera. After installing the program, you need to calibrate the device by placing it on a flat surface.
As you understand, the level for android cannot be considered as a full-fledged tool in the construction of a bath. Although using this level it will be quite possible to hang pictures evenly in the rest room.
conclusions
During the construction of a bath, as in any other construction, one cannot do without a building level. Since our site is designed for amateur builders, we dare to offer the following gentleman's set:
- Hydraulic level (required);
- Bubble level (required);
- Chinese laser level (you can do without).
This whole set can be bought for only 1000 rubles and it will be enough for all types of work, from pouring the foundation to laying tiles.
