No matter how small or large the steel structure project we received, initially we had to make the budget first, and the price of this project could be determined most often after several consultations. But how is this budget price calculated, and what is the calculation to have the most total budget price? The owners are actually very ignorant of these and very confused. Qingdao Yili Steel Structure will share with you the quotations made by professional budgeters mainly from those parts.
To put it simply or how many people have knowledge of steel structure, people make steel structure budget mainly from the following aspects:
The main components of the steel structure mainly include: steel columns, steel beams, crane beams and other large main components
The steel structure secondary components mainly include: purlins, inter-column supports, horizontal supports, tie bars, braces, casings, etc.
Plus some stiffening plates, connecting plates, anchors, high-strength/ordinary bolts. All the components are basically complete.
After the construction volume is calculated, the labor cost, transportation cost, etc. are calculated through the volume.
But if you want to calculate the quantity, you must have a set of drawings of the steel structure factory. Looking at the drawings, looking at the structure of the project, and then disassembling the drawings, the final budget is not a problem. Let's step by step in detail.
By clearing the drawings, we can find out how many roommates in a steel structure workshop are made of door-type steel frames. Then according to the length, material and quantity of the steel column, calculate the weight of the steel column. In turn, steel beams, crane beams, roof purlins, and then horizontal support, tie rods, tie rods, casings and the like can be calculated, all of which belong to the roof system. Then the following are the components on the wall surface such as wall purlins, inter-column supports, door columns, window columns, ponchos and the like. There is no requirement to count the order first, but the missing items are not allowed.
In addition, when calculating the main component, it is best to bring stiffeners, connecting plates and the like, such as a steel column with a column bottom plate, the column bottom plate also has stiffening, the column body may also have a corbel, purlin support plate, and a cover Plate, and the connecting plate with the beam. These things are best counted as accessory steel. This will make it more detailed.
Finally, the anchor bolts and bolts are counted. From the drawings, we can easily see that each column foot requires several sets of anchor bolts, and each connection point requires several sets of high-definition bolts and ordinary bolts. Then multiply the number of pedestals and the number of connected nodes to easily calculate the number.
Of course, sometimes the roof color plate and wall color plate are also counted. Plus the cost of paint, accessories, labor, transportation, accessories, management fees, water fees, etc.
