How to estimate fire protection engineering by point, and how to calculate the amount of work for he

What is a fire engineering point?

1. Labor cost = (working day consumption daily wage unit price).

2. Material cost (material consumption, material base price) + inspection and test fee.

Labor cost is also known as "basic salary of construction and installation workers" or "fixed labor cost". It refers to the basic salary, additional wages and wage allowances (such as coal stickers, grain allowances, non-staple food allowances, etc.) of workers directly engaged in the construction of construction and installation projects (including auxiliary workers such as horizontal and vertical transportation on site) and auxiliary production workers.

However, it does not include the wages of administrative and technical personnel, personnel who procure, store and drive various machinery and vehicles, handling and unloading workers before materials arrive at the site warehouse, full-time trade union personnel, medical personnel and other personnel who are paid by construction management fees or non-operating expenses.

The practice of fire engineering budget is: pay attention to the calculation of engineering quantity, and the pipeline avoids the beam position, air duct, water supply and drainage pipe, etc. The pipe Song Zheng diversion bracket is a pipeline above DN32 to be calculated separately, and DN32 is included in the quota.

Fire alarm: The pipeline calculation needs to avoid the increased workload of beam positions, air ducts, water supply and drainage pipes, etc. The number of weak current cables needs to be increased according to the regulations.

The ** of the equipment is based on the field judgment.

Commonly used list: fire sprinkler galvanized steel pipe 25-150, fire hydrant galvanized steel pipe DN65, DN100, DN150 water flow indicator, signal butterfly valve, pressure reducing orifice plate, wet alarm valve, sprinkler head, automatic exhaust valve, end water test valve, fire hydrant, dry powder fire extinguisher, clamp butterfly valve.

Generally speaking, it is to count the number of varieties of fire-fighting equipment and equipment that need to be done, and then according to the local price level, the total price of these equipment and equipment is counted and summarized, so that you can know the total number of fire-fighting equipment and equipment, which is the fire budget.

First of all, read the drawings carefully and read the design instructions, and then list the items, in the calculation, the quota to make up the main material, and there is not to set the difference, to see if there is any need to debug.

Look at the drawings, calculate the materials, and set the quota.

Mainly understand the professional knowledge of fire protection first.

What software do you use or what does it mean, landlord, you ask so vaguely.

Budgeting method for fire engineering contractors.

1. Calculation of sprinkler system contractor.

1.Calculated according to the construction area: 1) 10 11 yuan m2 per square meter 2) The difficult thing to do is 14 17 yuan per square meter m2.

2.Calculated by meter: one meter by 21 25 yuan m.

More than 10,000 square meters are calculated by meters: 25 yuan m.

10,000 square meters by meter: 28 yuan m.

2. Calculation of fire hydrant system contractor.

1.Calculated according to the construction area: 5 yuan m2 per square meter.

2.The fire box is calculated by one: 30 yuan, 50 yuan (with self-rescue plate).

3. Automatic alarm system.

1.Calculated according to the construction area: 30 50 yuan m2 per square meter.

2.Calculated by point: 55 yuan.

Fourth, the pump room contractor calculation.

Each pump below kilowatt is installed at 1200 1300 yuan.

1,500 yuan per pump below kilowatts.

3.According to the cabinet according to the point of calculation, each point: 1200 1500 yuan point.

Wet alarm valves and so on are connected to the host through the coding module, and only the module is counted as points.

The fire point is generally understood to refer to the point of the fire alarm, that is, the smoke detector with the address, the hand report, the input module (the pressure switch, the water flow indicator, the fan and other mechanical equipment play a contact function), and the control module are all within the scope of the point calculation.

Junction boxes do not fall under the category of points. Above, please refer to.

The dots in all alarm drawings are the same**; 70 yuan.

**This machine and the module are counted as one point each. It doesn't count as points.

The fire quota should first be counted according to the drawings, input into the pricing software, and then enter the main material cost, take the measure fee, the regulation fee, the rate, and other measure fees, etc., and calculate it can be obtained.

It is necessary to be clear what kind of equipment is installed, what type of equipment is used, and similar quotas should be applied. The pipeline should find out the high, medium and low pressure, wall thickness, and pressure level; The cable should be clarified as the specific cross-section of the flame-retardant shielded cable of the copper core cable, and the quota should be applied. Bracket fabrication and installation of piping systems.

In addition, commissioning costs will be added. There are also pressure tests, strength tests, etc. for different fire protection systems.

Find out the actual installation situation, apply a similar quota, and then get the installation budget you need, use it for bidding, or negotiate the price with the next package.

Available at specialized architecture bookstores! It needs to be used in conjunction with the province's bill of quantities or other valuation methods!!

Which province do you have???

It's different in every province!!

Water: 8 firefighting sets, 7 useless sets, 7 sprinkler sets, 8 useless sets, 8 sets;

Electricity: Set of 7 volumes, 7 volumes of useless sets of 2 volumes.
