Two, you can find a good set of budget, print out, and then one by one to see the author's thinking - why so set? Why can this set? What are the benefits and drawbacks of such a set? How do you think you can set (in line with the provisions of the quota and the description of the case, often a budget item can have several budget quotas to set), and then the price will be different in where you can choose how to set according to their own position (party A or party B units)!
First of all, according to the unit project construction drawings to calculate the list of items of each sub-part of the project contains subheads of the amount of work; and then the subheads contained in the group price (you can set the quota), labor, materials, machinery, fee, the formation of subheads of the comprehensive unit price, the subheads of the price of items of the amount of work multiplied by the price of the comprehensive unit price, resulting in the integrated price, the subheads of the integrated price of the list of integrated prices, and the list of integrated prices of the sum of integrated prices, the list of integrated prices, the list of integrated prices. List of comprehensive price divided by the list of works to list the comprehensive unit price of the item.
And then the list of sub-projects will be multiplied by its corresponding comprehensive unit price, the product is the full cost of the sub-projects required; cumulative product and summarized, it comes to the unit of work of all the sub-projects of all the sub-projects fee. This preparation method is suitable for the work, materials due to price changes occurring in the market economy needs.
2.1 determine the comprehensive unit price should pay attention to the following matters:
(1) based on the project description. When there is a list of project features description and design drawings do not match, the list of project features description should prevail, to determine the bidding price of the comprehensive unit price. To the construction, hair, the contracting parties and then according to the actual construction of the project characteristics, based on the contract to re-establish the comprehensive unit price.
(2) the handling of materials provisional estimate. Bidding documents in the list of other items provided in the tentative price of materials, should be based on its tentative unit price into the comprehensive unit price.
2.2 Measures for the preparation of the list of items pricing table
Measures for the list of items pricing should be based on the construction organization design of the bidding project, can calculate the amount of measures for the project is appropriate to use the list of items of work by parts of the way to adopt a comprehensive unit price; the rest of the measures for the project can be 'item' as the unit of the way Pricing, should include all costs other than fees and taxes.
The list pricing specification stipulates that the safety and civilization construction fee in the list of measure items should be priced in accordance with the prescribed fee standard of the national or provincial and industry construction authorities, and this fee cannot participate in the market competition.
2.3 Preparation of other items and list pricing list
Other items include provisional amount, provisional estimate, day labor and general contracting service fee, and the bidding price should follow the following principles: the provisional amount should be filled out in accordance with the amount listed in the list of other items, and shall not be changed; the provisional estimate shall not be changed and altered; the day labor shall be determined independently in accordance with the list of items and estimated quantities of the items. Estimated quantities, the comprehensive unit price of each item shall be determined and calculated independently; the general contracting service fee shall be determined independently according to the contents of subcontracted professional works and the supply of materials and equipments listed by the bidders in the bidding documents, and in accordance with the requirements for coordination, cooperation and service and the needs for management of the construction site put forward by the bidders.
2.4 Fees and taxes are based on the relevant laws, regulations and policies, and are mandatory, and must be calculated in accordance with the relevant provisions of the national or provincial and industry construction authorities at the time of bidding.
(1) Bidding documents, bill of quantities and its supplementary notices, and minutes of Q&A.
(2) Construction engineering design documents and related information.
(3) Construction site conditions, project characteristics and the proposed bidding construction organization design or construction program.
(4) Standards, specifications and other technical information related to the construction project.
(5) The construction cost information or market price information issued by the local construction cost management organization.
(6) Engineering site investigation information such as natural conditions and construction conditions in the construction site.
(7) Other relevant information.
Taking frame structure as an example:
1. Earthwork
Site leveling, excavation (manual, excavator), earth transportation (in-situ, transportation), earth backfill (excavation, transportation, backfill). Pile foundation, take vibratory grouting pile as an example: pile driving (pay attention to the empty part), pile tip burying, reinforcing cage, chiseling pile head.
2, bedding
Bedding, waterproofing. Foundation, structure: beams, slabs, columns (whether there are arcs, starting slope, etc.). This part of the main structure should be no problem.
3, masonry
What brick, mortar type, a brick or half a brick or more than one brick. Some places in the basement meet certain conditions also add lighting fees, note that some foundations have a brick tire membrane underneath.
4, concrete works
Generally calculated by volume, stairs, balconies by projected area (straight, curved). Some areas of the room plate is counted to the edge of the beam, some areas are beams merged into the plate calculation. Columns count the height of the floor. It should be noted that the over-beam, structural columns (horse tooth hewers), sill plate, decorative lines, balcony terrace anti-beam, roof and other small components, staircase counting the boundaries should be noted, basically according to the square calculation. Template: bedding, foundation, foundation beams, beams, boards, columns, beams, structural columns, small components, stairs, balconies, balustrades and so on.
5, reinforcing steel
Pile cage (general atlas, do not forget to fix the bar, spiral hoop bar calculation), each member of the reinforcement bar, hanging bar (main and secondary beams junction), hole reinforcement bar, shear wall with end columns, wing columns, etc., when the tie bar, wall tie bar (generally 600 * 600), bench bar, column tie bar, plate distribution bar, plate surface negative bar, partial Reinforcement, balcony and other protective layer will generally be equipped with reinforcing mesh, over the beam, sill plate, small components such as internal reinforcement, masonry reinforcement.
6, roof
protection layer, leveling layer, waterproof layer, grass-roots level, surface layer. Look at it against the detailed drawings, pay attention to the flooding, drainage: water bucket, downspout, grate, water fall pipe, elbow.
7, scaffolding
Some places are in accordance with the external walls, internal walls are counted separately, some are in accordance with the floor area. Some areas also have single beams, columns, pick scaffolding, mile scaffolding and so on. Floor height of more than 3.6m to calculate the full hall scaffolding, pay attention to the super-high transportation increase fee. Basement using non-pumping to calculate the scaffolding.
8, vertical transportation costs
Generally in accordance with the floor area, some areas in accordance with the fixed labor as the basis for calculation, this is better.
9, high increase fee
Fixed height. Look at two kinds of: one, layer height of more than 3.6m (or 6m), two, eave height of more than a clear calculation of the base is good.
10, windows and doors
General installation hole area calculation, special according to the gage. It should be noted that the door is a wooden door, aluminum alloy, plastic steel or security doors, casement door or sliding door, rectangular door or curved door, the thickness of the door frame, flat or flat or standing in the gage; window with the door, but the window there are upward-swinging windows, downward-swinging windows, casement windows, sliding windows, fixed windows, etc., respectively. Doors and windows should also pay attention to windows and doors, hardware installation (generally does not contain locks), wooden doors generally have a brush varnish (according to design requirements), windows should pay attention to the sill plate, curtain box, rail installation.
11, railing handrails
Note that the railing and handrails are generally counted separately, generally in accordance with the extension of meters, slope section * 1.15, note that the joints are also counted length. If the railing is metal, generally have to brush red Dan anti-rust paint, wooden handrail brush polyurethane paint (according to design requirements). General quota will be these paints in accordance with the quality of calculation (t), depending on how you grasp the data, I generally in accordance with the 10kg/m-12kg/m calculation, metal handrails are generally 4.8kg/m, note that you need to multiply by the coefficient, generally 1.71. cast iron railings, fences depends on the data, this is a little heavier.
12, ground works
Ground painting is generally calculated in accordance with the net area between the main wall, wall stomp, column stomp is not deducted, the door, the empty circle openings are not increased. Block material surface layer to increase the opening area. Bathroom and waterproofing, slope (average thickness). Stairwell's general side, roof included. Pay attention to the practice.
13, wall decoration
Interior walls, painted cement mortar or mixed mortar, thickness, waterproofing, insulation, surface putty, latex paint or tiles, brick specifications, door and window sidewalls to increase the attention to the wainscoting; exterior walls: painting, insulation, surface (paint, granite, marble). Generally speaking, now also in the brick, concrete surface junction hanging network, brush interfacial agent. Skirting is generally calculated according to the extension meter, without deducting the length of the hole. Canopy: painting, surface, ceiling, pay attention to whether there is a drop, the type of ceiling keel, the surface has a folded part to unfold the calculation. When painting the side of the beam is generally incorporated into the ceiling calculation.
14, peripheral
Steps, platforms, decorative vignettes, steps, painting, surfacing, whether the steps on both sides of the handrail, green, open ditch (cover), manholes, septic tanks, etc. There are standardized practices, directly set the quota on the line.
