The decoration company's quotation is mainly based on the actual charges, so that the control of the budget has a relatively large fluctuation, we even heard about the hydropower construction can increase the budget 5000-10000 yuan painful experience Feeling why the cost of utilities is so much lower than the budget, today we look at what the tricks of hydropower are and how we can accurately calculate our actual costs. Hydropower is generally divided into two phases. Today, we communicate the first part of the project, the latter part of the installation project, the next exchange.
1Slotting fee
This is our common slotting pricing quote. Apart from distinguishing different wall charging standards, there is no mention of any billing standards. This brings about the possibility of the next generation of costs.
Counting tricks:ⶠactual number is slotted to open up the slot or in the calculation of the number of line pipe tank calculation, there is a big gap between the costs go, the normal situation is calculated according to the number of slots ray tube than the actual opening of the tank at least to Double the number.
How to calculate the installation cost of a twist box
Whether the budget for this expense includes the slotting cost of the cassette, if it is not included, is how to calculate, after all, each household's switch panel is about 50.
Paid management fees
Line pipe includes water pipe and electric pipe
This is the conventional water-pipeline project that every one of us will do. The main problem in this area is the calculation method of the drainage pipe, which is calculated by pressing the outlet of the water or calculating by the area or by the number of meters. Big.
Line costs
                      
The gap between these is relatively large. The price of common items in the quotation of this project is the key to the unit price of the accessories. There is also the requirement that some decoration companies will wear out these percentages. In addition, the reservation line for each cassette must also be charged with the corresponding pipe wear, according to 50. A cassette calculation, the total length of all reserved lines is about 30 meters.
Reform of strong and weak electric box
Whether these expenses are complete, especially whether the installation of the air switch needs to be charged, this is also a hidden cost for many decoration companies.
5TV line embedded pipe
It is to hide some of the lines for the beauty of the background wall.
Slot cost
The cost of sealing the slot should be reduced for the users who partially remove the wall to the red brick. This is also a concern.
7Accounting quantity
For on-site confirmation of the quantity of water and electricity after acceptance, it is easier to calculate for the line box, but the number of lines, wires, and slots, in addition to the agreed counting method, we need to take a tape measure on site, but now the decoration company is mostly According to the number of delivery orders, the remaining quantity will be subtracted to obtain the actual quantity used, which will also have a large difference, for example, the workers will use wires to fix the pipelines, wrap the materials, etc., or some workers will opportunistically, resulting in The number of actual use is often not so many. The amount of these multiple calculations not only increases our material costs, but also accessories and labor costs.
The budget of hydropower is difficult to control. In addition to some tricks of the company’s billing fees, it will also be affected by the route of the line. The direction of the line will be different, resulting in a large number of differences, the normal 2 room 90 The square of the wire, if all the new row of lines, the approximate number should be around 800-900 meters. If the quantity on the quotation is too low, it is necessary to take care that the company is tempted to offer a low quotation, sign a decoration contract, and then use the actual settlement to increase the renovation budget in disguise. The most general result is that our budget and actual settlement will be So big difference. (This image is from the network)
