Chapter 1: Overview of installation budget work
I. Calculation Part (General)
1. When calculating the engineering quantity, it is necessary to classify the engineering quantity by specialty and calculate the engineering quantity of each division separately.
Such as lighting, power, lightning protection and grounding, telephone, television, network, security, alarm and so on. Calculate and summarize by division in 1 electrical specialty; Pump room, drainage, water supply, hot water, rainwater, pressure sewage, fire fighting, etc. Calculated and summarized by the water supply and drainage professional division; Note: Indoor fire hydrant works must be classified separately because of the need to record debugging fees, and cannot be mixed with water supply and drainage.
2. Pay attention to the items not reflected in the drawings.
1. Items that need to be listed separately include: bracket installation, electrical adjustment test, motor wiring and debugging, dry powder fire extinguisher and electric welding machine, etc.
2. Items that do not need to be listed separately but should be calculated according to the work content, such as casing, disinfection and flushing, hydraulic test, rust removal and oil brushing, heat preservation, terminal wiring, wall slotting, drilling, sporadic earthwork, pipe joints, etc.
3. Pay attention to the calculation of hand dryers, sanitary cartons, mirrors, soap boxes and other items that need to be coordinated in the decoration project.
4. The bill of quantities shall be filled in by division, sub-item, classification, stratification or subsection, and the superelevation, pipeline well and thermal insulation parts shall be listed separately, so as to make a list or set a quota;
5. When calculating the distribution box, write the terminals and cable heads in the box directly below the distribution box, which is convenient for calculating the number of terminals and additional quantities when assembling the price (it is best to use a spreadsheet to calculate automatically).
6. When pricing with the bill of quantities, be careful not to omit the adjustment coefficient of the main structure, the debugging fee of the fire hydrant pipeline, the ultra-high fee, the increase fee of the high-rise building, the scaffolding erection fee and the debugging fee of the station project.
Second, the electrical part:
1. When calculating piping, pay attention to the floor height to facilitate the calculation of vertical pipe length, and classify bright and dark wiring pipes according to specifications. Note: The laying quota of exposed pipes along the wall has included the laying of brackets, and the brackets for pipe distribution in the ceiling need to be calculated separately.
2. When the electrical equipment distribution box is attached to the equipment, only the installation fee and debugging fee (such as frequency conversion control debugging) are calculated, and the unit price of the main material of the equipment is included in the quotation of the corresponding equipment (water, electricity and heating drawings need to be compared).
3. When calculating the pipeline of radiant heat project, pay attention to increase the floor thickness of radiant heat.
4. When laying cables in the pipeline well, pay attention to whether the electric well is a vertical channel. When the cable is laid in the vertical bridge set in the floor well, the vertical channel cable should be adopted.
5. 10KV introduces the concepts of hills and mountains into overhead lines; Hilly land refers to the area with 30-50 meters of topographic relief within the range of 1 km. Generally, a mountainous area refers to an area with a relief height difference of 30-50m within 250m.
6. Quantity to be calculated when pricing the bill of quantities:
Distribution box (terminal wiring in the box, production and installation of floor-standing foundation channel steel);
Motor (check motor wiring and debugging) Note that motors with complete equipment configuration will not be debugged.
Lightning protection grounding (grounding of high-rise aluminum doors and windows, jumper, test, equalizing ring, equipotential debugging, etc.). ) Bus duct (bridge fittings, bracket installation, box installation and debugging) There is no need to debug cables (protective tube, cable head, multiplication factor, fire prevention measures, digging, sand laying and brick covering) when inserting bus duct.
Wiring (laying in pipes or bridges)
Third, the water supply and drainage part:
1. When pricing the pipeline list, the supporting waterproof casing shall be calculated according to the pipeline diameter, and the general steel casing shall be calculated according to the pipeline body size.
2. When calculating the engineering quantity of the water pump house, some drawings only indicate the position of the water pump, without detailed drawings, so it is necessary to refer to the standard atlas for calculation. For each water pump, 4 shock absorbers, 2 pump connectors, 2 flexible joints, 1 check valve, 2 block valves, 1 drain valve, 1 pressure gauge and pump foundation grouting are considered. The hot water pump has thermometer and water processor; The sewage pump has a liquid level controller. If there is no water pump foundation in the civil engineering drawing, the steel bearing should be calculated.
3. When calculating the heat exchanger or container, we should consider the matching thermometer, pressure gauge, exhaust and drain valve, heat preservation, support, disinfection and flushing, and pressure test, in which the thermometer should calculate the matching sleeve, and the pressure gauge should calculate the matching installation of the source accessories and the bending installation of the pressure gauge. Hydrostatic test, water flushing, heat preservation, etc.
4. When calculating the pipeline quantities, it should be noted that the indoor pipeline has included bracket installation, and the outdoor pipeline bracket shall be calculated separately.
5. Pay attention to the outer diameter of the water supply plastic pipe casing according to De, and the drawing design is generally DN (engineering diameter) inner diameter.
Fourth, the HVAC part:
1. The length of various components (various control valves, silencers, static pressure boxes and fans) shall be deducted from the calculation of air duct system.
2. The bracket quota of the air duct has been included, but the derusting and oil brushing of the bracket should be calculated, and the air duct is designed to be oil brushed.
3. When calculating the fan coil unit, 1 automatic exhaust valve, two control valves, 1 electric two-way valve, 1 filter and a thermostat should be considered.
4. Two automatic exhaust valves, two pressure gauges and thermometers, two control valves, 1 electric control valve, two soft connectors, 1 filter, a temperature controller and bracket installation are considered in the calculation of air conditioning unit.
5. Two water supply and return control valves, electric valve, supply valve, drain valve and ball valve are considered in the calculation of cooling tower.
6. Pay attention to the fan shock absorber, canvas soft connection, equipment bracket installation, rust removal and oil brushing when installing the fan or air conditioning unit.
7. The cabinet fan box is designated as centrifugal fan box.
8. Plate smoke outlet, positive pressure air supply outlet and electrical device shall be equipped with fire dampers. If there is no manual operation, there must be a control valve installation project. (Note that this kind of tuyere is generally combined)
9. When the side length of rectangular air duct is longer than (horizontal side length) "$2", guide vanes must be set.
10. Multi-connected air conditioner is suitable for outdoor installation of one outdoor unit and multiple indoor units, and the indoor units are equipped with fan coil units (wall-mounted); Refrigerant using non-aqueous medium needs to be calculated separately according to actual needs.
1 1. air defense closed casing: type I closed casing: suitable for direct pouring of sampling pipes, piezometers, compressed air pipes and iron air pipes into concrete walls; Type ⅱ closed sleeve: it is suitable for iron air ducts that are not directly poured into concrete walls; Three types of closed casing: the air duct passes through the brick wall; The hole plugging cost is not included in the quota, and the civil engineering quota is implemented.
12. The installation of split air conditioner includes the installation of indoor unit and outdoor unit.
Verb (abbreviation for verb) municipal installation:
1. Attention should be paid to the earthwork excavation of lamp foundation, lamp foundation, lamp pole, lamp cap, light source, down lead, terminal board, terminal board wiring, grounding electrode, grounding price crossing and grounding electrode debugging.
2. The lamp height is greater than10m, and the labor cost is * 1.4 coefficient. Pay attention to adjust the floor material according to the current market price.

Chapter II: Annual Work Summary of Installation Budget Officer 20xx
Installation cost of sales department of Xx Engineering Co., Ltd.: xx
20xx passed the recruitment in July and became the installation cost engineer of the business department of xx Engineering Co., Ltd. In a blink of an eye, we will wave goodbye to 20xx and usher in a brand-new 20xx year! Time flies, it has been half a year since I came to this big family.

(11) 65438+Late February: xx project change visa settlement, measurement and pricing. Summary of visa change requirements
Quantity and price.
Second, the ideological aspect.
Abide by rules and regulations, unite with colleagues, seek truth from facts, be optimistic, always maintain a rigorous and serious work attitude and meticulous work style, and work hard. Carry forward the fine tradition of being hard-working and ready to help others, always be an honest man, work hard, be hard-working and simple, and discipline yourself in strict accordance with the company management system of Sichuan Lida Electrical Engineering Co., Ltd.
Third, personal understanding.
Through the above work, I realized the importance of the business department's work, and at the same time made clear my job responsibilities, and got a deeper understanding of the pre-settlement and bidding work: I will carefully analyze every problem found in my work and get a reasonable answer, striving for the shortest time and the most reliable answer. I found my own shortcomings in time at work. Judging from my experience in auditing and budget settlement for more than two years, these have just begun. There are still many unknowns about the new construction technology and standards. In the future work, I will try to get in touch with reality, contact the construction site and learn more laws and regulations. For a cost engineer, it is not a simple drawing operation, but to be very familiar with every construction link, every construction technology and various construction organization measures, and to use them skillfully. Only by being well informed and constantly learning new technologies, new materials and more experience in construction measures can we make a more accurate and competitive quotation in combination with reality. Therefore, the comprehensive unit price of the bill of quantities should be determined according to the bid evaluation criteria, so as to reduce the bid price as much as possible. But it should not exceed its stop-loss price, and it should be reasonable to consider whether the settlement can keep the cost.
For budget work, accurate and fast quotation is needed. Familiar with the site, it is not enough to have construction technology and more construction measures. To meet the requirements of rapidity and accuracy, we should also pay attention to the accumulation of experience. So I make a request to myself: I will "try my best" to analyze every project I do, and "try my best" means to be as perfect and meticulous as possible. In the future work, careful calculation, careful thinking, careful summary and careful analysis of data will be of great help to improve your professional level.
The above is the summary of my work in 20xx, and the prospect and arrangement of my future work. The new year means a new starting point, new opportunities and new challenges. Our business department will certainly correct the shortcomings of the past in the new year and improve its ideology and knowledge and skills. Of course, in the new year, I will treat everything more attentively, work hard and make progress with the company!
