Precast, one of the most popular products in building materials in recent times, offers various advantages for both construction companies and users. Precast can be seen in every building. However, there is a point to be noted here, which, if overlooked, can affect the aesthetic appearance promised by precast. The mentioned precast measurement calculation can yield different results for each project.
In measurements, a complete building can be taken as a basis, or precast can be used in a specific part of the structure. There is generally a situation that many people do not take into account. It is the cheek parts where precast facade panels come into contact with each other. When making measurement calculations, including these points can result in the most accurate measurement. There are step-by-step points to be followed in the part of how to calculate precast measurements.
What is Precast Measurement Calculation?
Measurement calculation is used to ensure the production and construction of all building elements in construction. This means measuring each point of the structure individually. It is calculated line by line to ensure that there is no shortage or excess.
Based on this measurement, building materials are prepared, and the amount of work is determined. All arrangements are made based on the result obtained almost immediately. Measurement calculation also varies in different processes such as formwork, concrete, and wall.
- Weight measurements are made with measurement scales,
- Lengths are measured in meters,
- Areas are measured in square meters along with width x length,
- Volume measurements are calculated by multiplying width x length x height, measured in meters.
Precast panels can have flat surfaces as well as indentations and protrusions. These are also included in the calculation.
Methods for Precast Measurement Calculation
The value taken for precast measurement calculation is the square meter calculation. Cross-sections are taken in precast facade elements such as precast cornices, floorings, columns, and corbels, and multiplied by the meter length calculation. In addition to square meters, meter lengths, and total cross-sectional information are also obtained.
For example, if the perimeter of a roof is 60 m and the roof trimming section is 2 mm, the total roof trimming around will be found as 120 square meters. However, as we mentioned earlier, it can vary depending on the desired design. Generally, it is included in the projects as a ready-made draft. The total figure obtained may vary depending on the designs requested by the customers.
In precasts made in buildings, window openings are not included in the measurement calculation. The reason for this is that including the precast void with 15 cm on the walls where the edges of the window meet and with 25 cm from the window, in the meters, would be the same.
Posing Precast Elements
In the processes carried out for precast exterior facade design, posing is performed according to the 3D visuals prepared by the employer or the company according to the designs. Using incorrect units of measurement will show the project as faulty and incomplete. Posing must be done to show all parts of the structure without missing any. According to the designs in 3D, each pose is given separately in the measurements with posing. Therefore, separate pricing can be done for square meters and meter lengths in posing.
