Provisions on the calculation of greening project cost?

The cost of greening and planting project consists of two parts: one is the direct cost of the project; The second is the indirect cost of the project. The following is an introduction to the main contents of the Provisions on Cost Calculation of Greening Projects brought by Zhong Da Consulting for your reference.

As the name implies, the direct cost of the project refers to the direct cost of completing the greening and planting project, which mainly includes three aspects.

1. Labor costs: including all labor costs such as lightering, digging holes, changing soil, planting, covering soil, water conservation, fencing and maintenance within one month after the seedlings are purchased to the construction site.

2. Material cost: including the cost of seedlings of different varieties and specifications, as well as the cost of auxiliary materials necessary for planting. Auxiliary materials include water for seedling irrigation, straw rope for trunk protection, lead wire, and various materials such as bamboo piles, wooden piles and cement piles.

3. Mechanical expenses: including the mechanical loss expenses caused by lifting, resetting and righting when large-sized seedlings cannot be manually lifted.

Labor, materials and machinery are all stipulated in the quota. In general, it is not allowed to change at will. However, the quota is based on normal construction methods to determine labor, materials and machinery costs. Due to the ever-changing conditions and climate of the construction project, the quota also stipulates that for the uncertain factors beyond the quota, Party A and Party B shall separately increase the project cost according to the actual situation of the construction site, but only after mutual consultation and agreement, and supplementary terms shall be clearly added in the construction contract, can the project cost be increased.

The indirect cost of the project refers to other expenses that the construction enterprise must charge after the greening planting project is completed, and it is an indispensable part of the greening project cost. Including: expenditure and management expenses of technical management personnel of construction enterprises, legitimate profits of enterprises and taxes paid to the state (or higher management departments).

How much the indirect cost of the project is charged is based on the scale of the greening planting project, which is uniformly and clearly stipulated by the municipal construction project quota management station and cannot be increased or decreased at will.

Calculation basis of greening planting project cost

First of all, there must be a complete green planting project construction design.

The design of construction design drawings shall be designed by Party A (the owner) with the qualification of greening design. According to the investor's specific environment, topography, ornamental and use requirements and investment amount, they will design construction drawings that are not only beneficial to the function of plant growth, ornamental and use, but also ensure the rational use of funds, and allocate the number of seedlings of different varieties and specifications to achieve the expected effect of the investor.

Secondly, there should be market price information of seedlings that matches the project construction period.

The price of seedlings changes according to the fluctuation of market price in different construction time, so the expected cost of the project must be calculated according to the current market supply price of seedlings before construction, that is, the box calculation scheme of how much it costs to complete a green planting project.

The market price information of seedlings shall be subject to the price information released by the municipal construction engineering quota management station. There are generally two ways.

1, release the project cost information in the first month of each quarter.

2. According to last year's seedling price, comprehensively determine the budget adjustment price of engineering seedling materials.

(4) Calculation method of budget cost of greening planting project.

The general procedure for calculating the budget cost of greening planting project is as follows:

First, according to the name, variety, specification, quantity of engineering seedlings on the construction design drawings and the corresponding unit price of seedlings in the market price information, multiply the quantity and unit price to calculate the complex price. Then add up all the complex prices and work out the total cost of seedlings needed for this project.

Second, according to the terrain elevation required by the construction design and the actual situation of the terrain and soil quality of the construction site, determine the construction scheme, calculate the excavated quantity, meet the design terrain elevation requirements and drainage requirements required for plant growth, and then calculate the cost of garbage soil and planting soil respectively according to the earthwork unit price specified in the document.

Three, according to the relevant provisions of the construction area and quota on the construction design drawings, calculate the labor costs required for earthwork leveling, scarifying and clearing the green space before seedling planting.

According to the name, variety, specification, quantity and corresponding base price of Buddhism in the construction design, the accumulated income of labor, materials, machinery and other expenses required for all seedling planting in this project is calculated, which is the total planting cost of this project.

Four, the above three costs together, constitute all the direct costs of greening and planting projects. On the basis of this data, according to the rate standard and calculation program stipulated in the quota, all indirect costs of greening planting project are calculated.

To sum up, the total cost of a green planting project should be calculated as follows.

Total cost of greening and planting project: direct cost 1 seedling cost; 2. Earthwork cost; 3 planting costs (including green space consolidation costs) indirect costs (including management fees, corporate profits, taxes and other costs).

(5) How to determine the unit price of engineering seedlings?

In the greening and planting project, the cost of engineering seedlings is the main material, which accounts for a considerable proportion in the whole budget. Determine the name, variety, specification and quantity of seedlings according to the construction design drawings, and determine the unit price of seedlings corresponding to their names, varieties and specifications in the following order:

(a) there is a corresponding unit price in the guidance price, and the unit price of seedlings is determined according to the unit price in the project cost information.

(two) there is no guidance price, according to the last year's "engineering seedling materials budget adjustment price" data unit price to determine the seedling unit price.

(3) When there is no corresponding seedling unit price in the guidance price and budget adjustment price of engineering seedling materials, there are generally two possible situations.

The first possibility: with the development of landscape construction, the improvement and popularization of gardening level, the introduction of garden plants at home and abroad, and the emergence of local hybrid new varieties, more and more new varieties are planted in the process of greening, which is a good thing. However, as an engineering seedling market price data collection unit, it cannot be released in time.

Mainly based on the following reasons:

(1) Whether the new garden plant varieties are suitable for the climate and environmental characteristics of Shanghai is under observation.

(2) The market price information of new varieties of garden plants is still being collected, the information is not complete enough, and the release conditions are not mature. The second possibility: Garden plants generally have an optimal seedling age transplant period. The seedling size of the project is too small-it can't achieve the expected greening design effect; The scale of seedlings in the project is too large-as the saying goes, "people move to live, and trees move to die." Therefore, in general, large-scale engineering seedling transplantation should be treated with caution. If necessary, corresponding technical protection measures should be taken (including: cutting roots in advance, packing mud balls, hoisting and transporting by large-tonnage vehicles, etc.). ), it will cost a lot of money

For the above two cases, if the corresponding price information of seedlings cannot be found, Party A and Party B can generally negotiate the unit price in advance, and the contract is clear, and settlement (credible information such as invoices and market quotations) can be adopted.

(6) How to calculate the earthwork quantity of greening planting project?

In order to ensure the normal growth of garden plants, according to the quality standard of garden planting soil, the earthwork of greening planting project should meet the requirements of water, fertilizer, gas, heat and various physical and chemical indexes. Therefore, it is obviously different from the general concept of earthwork in construction engineering and cannot be generalized.

When preparing the budget of greening and planting project, we must check the soil quality of the site in advance to see if it can meet the design requirements, and then reasonably calculate the earthwork quantity of the project according to the actual situation. The cost of earthwork has a great influence on the project investment cost and the later cost of seedlings. For greening and planting projects, earthworks usually have the following situations;

1. The original terrain elevation and soil quality meet the requirements of design and garden plant growth, and there is no need to increase earthwork cost.

2. The original terrain elevation meets the design requirements and does not need to be buried or unearthed, but the soil quality is too poor, so it needs to be buried in situ for deep excavation.

3. The original terrain elevation is too low, so it is necessary to plant earthwork outside the site.

4. The original terrain elevation is too high (or basically consistent with the design elevation, but does not meet the requirements of planting soil), so it is necessary to transport the garbage soil outside, and then plant earthwork.

5. The earthwork volume of the original terrain does not need to be buried or unearthed, but the terrain needs to be stacked again according to the design elevation and terrain requirements.

The construction unit shall determine the construction scheme of planting earthwork according to the above analysis and the actual situation of the construction site. To determine the earthwork construction scheme, the opinions of the designer and the competent personnel of the investor should be solicited in advance, and the corresponding written records should be handled as the basis for calculating the earthwork cost of the greening planting project.

According to the Technical Specification for Planting Garden Plants, soil containing construction waste, saline-alkali soil, heavy clay, sandy soil and soil containing other harmful components should be replaced with planting soil in whole or in part according to the design requirements. General requirements for quota: the thickness of soil for lawn planting should be not less than 30cm, that for trees should be not less than 1.0m ... that for shrubs should be not less than 0.8m..

The calculation of earthwork volume should be based on various construction methods, such as in-situ burial of garbage soil, truck transportation of garbage soil into planting soil, artificial lighterage of planting soil field, artificial stacking of terrain, green space layout, etc.

(7) How to calculate the earthwork cost of greening planting project?

Earthwork cost should be calculated item by item according to different construction methods, and then combined with the corresponding earthwork unit price, and the cumulative sum is called the total earthwork cost of greening planting project.

The general calculation method is as follows:

1. When the original terrain elevation and soil quality meet the requirements of greening design and plant growth, and there is no need to increase earthwork separately, the content of a green space consolidation project can be calculated. Green space layout is an essential construction technology before planting garden plants. Calculated by square meters, the basic earthwork price of the corresponding subtitle can be applied to the "93" garden quota.

2. When the original terrain elevation meets the design requirements, but the quality of a small amount of earthwork does not meet the requirements of plant growth, the construction method of turning the good soil deep to the surface and burying the garbage deep underground can generally be adopted. Earthwork quantity can be calculated according to the actual excavation quantity (length × width× depth), and the unit price can be selected with reference to the base price of related subheadings in Chapter 2 of Garden Quota Earthwork of Jiu San Society.

3. When the original terrain elevation is too low and the soil is obviously lacking, planting soil (car) is generally used to solve it.

4. When the original terrain elevation is too high, and there is surplus soil to be transported abroad (or the garbage soil is not buried deeply), the unit price of planting earthwork specified in the document can be calculated according to the actual earthwork quantity transported abroad and the corresponding unit price.

5. When the terrain piled up in the construction site fluctuates greatly due to the design requirements, the amount of soil piled up can be calculated according to the different stacking heights with reference to the base price of the garden quota subtitle, and the terrain cost of earthwork piled up can be calculated according to the base price of the corresponding subtitle.

In actual construction, there is not only one situation because of the complexity, so we should distinguish different situations and calculate the earthwork cost item by item according to the different earthwork cost calculation methods introduced above.

(eight) how to calculate the cost of planting seedlings in greening projects?

Seedling planting is an essential construction process in greening projects. The calculation of seedling planting cost is to multiply the number of seedlings on the construction design by the corresponding base price of fixed planting cost, and calculate the composite price of this variety of seedlings. The cumulative sum of the composite prices is the fixed planting cost of this project.

The base price of fixed planting cost is determined according to various internal quality specifications of seedlings. The so-called internal quality specifications of seedlings are not the usual external dimensions such as height and crown diameter of seedlings, but the size indicators such as mud ball size, breast height and ground diameter of seedlings, which are essentially different.

According to the garden quota and the classification of seedlings, the internal quality specifications of seedlings are also different. Usually, when calculating, evergreen trees and shrubs are the size of mud balls; Deciduous trees and bamboo are based on DBH; Shrubs and hedges shall be subject to seedling height; Lawn planting methods are different; Climbing plants are based on different standards, such as the size of the ground diameter. , take a fixed planting cost.

So we are calculating whether the quality specifications and standards of seedlings are complete (generally, units with green design qualifications have the ability and should complete the above design requirements). Only when the quantity is correct and the quality specifications are complete can the base price of planting subtitle specified in the quota be correctly applied to ensure the correctness of planting cost calculation.

According to the provisions of the garden quota, the calculated project seedling planting cost, except for the planting, transplanting and protection costs of ancient trees, should include the seedling planting and maintenance work one month after the completion and handover (65,438+00 days for simple flower bed planting). The survival rate of engineering seedlings is 100%. After the handover is completed, if there are any dead seedlings, they can be officially handed over to Party A (the owner) after all replanting by the construction unit, and Party A (the owner) will carry out the daily management of later greening and maintenance.

(9) How to calculate the indirect cost of greening project?

The indirect costs of greening projects are the legitimate profits of enterprises and taxes paid to the state, which constitute the cost of greening projects. Generally, it includes two parts, one is fixed and the other is fixed; The other part consists of fees that can fluctuate with the market price and information released by the quota management station.

Fixed expenses include: management expenses incurred in the construction process, enterprise profits, state taxes and management expenses paid to superior units. Their calculation is based on the labor cost in the sum of seedling cost and fixed planting cost, and is determined by percentage rate. The percentage rate is determined by the fixed management station.

The determination of the percentage rate of various expenses varies according to the scale of greening and planting projects. If the greening project is generally contracted, if the construction area exceeds 6,500 square meters according to the engineering quantity determined in the contract, it will be regarded as the second-class project, and the specified percentage rate is relatively large; If the construction area is less than 6500 square meters, the specified percentage rate is correspondingly small; If the earthwork quantity of greening project is contracted separately and exceeds 2000 cubic meters, it will be regarded as Class III project, and the specified percentage rate is small; If the earthwork volume is less than 2000 cubic meters, as four types of projects, the specified percentage rate is correspondingly small.

The expenses that can be calculated by floating method include: compensation expenses for labor, materials and machinery, and expenses that can be negotiated by Party A and Party B according to the actual differences of construction site conditions due to the complex construction conditions of various projects, which we call "organization expenses".

General quota management station will regularly publish the unit price of market price information, and each project can calculate its cost according to these unit prices and the actual engineering quantity of each project. The calculation of start-up expenses takes into account the external environment of each project.

(10) Calculation of Greening Maintenance Cost

The protection of garden plants can usually be divided into three stages. The first stage is called planting period maintenance, and the maintenance period cost has been included in the base price of the garden quota subtitle, so the maintenance period cost cannot be calculated again.

The second stage is called lifetime maintenance. According to the Technical Regulations for Planting Garden Plants, the curing time is calculated from the end of the first stage. Among them, the seedlings planted before June of that year are until September of that year; Seedlings planted after June of that year must be planted until September of the following year. The maintenance cost is calculated according to the variety and quantity of seedlings, multiplied by the unit price of the corresponding maintenance level, accumulated, and then multiplied by various coefficients specified in the quota.

The third stage is called daily property management and maintenance, and the maintenance time is counted from the end of the second stage. According to the maintenance quota, the maintenance cost should be calculated according to the base price of the corresponding maintenance registration quota subtitle, and it also needs to be multiplied by various coefficients specified in the quota. If the maintenance period is one year, the maintenance cost cannot be calculated by the coefficient method.

The so-called maintenance level means that when compiling the maintenance quota, it is divided into three levels according to the maintenance standards of various gardens in this city, namely: parks and tourist areas; Community, unit category, and define the corresponding scope of application for reference. However, in practice, it can be adjusted according to the owner's funds. For example, some key parks can calculate their maintenance costs according to the first standard, and some non-key parks can also calculate their maintenance costs according to the second and third standards, and vice versa. This can not only meet the different needs of the market supply and demand sides, but also reflect the economic principle of the reciprocal relationship between expenses and obligations.

(eleven) how to confirm the cost of green planting project?

The preparation of a greening project cost only represents the unilateral will. Only after Party A and Party B negotiate and make corresponding adjustments, can it be regarded as the project cost recognized by both parties, and then it will be determined in the form of contract.

According to the spirit of the Interim Provisions of the Ministry of Construction on the Contract Price Management of Construction Projects (No.1999) and the characteristics of Shanghai's greening project cost management, both parties should pay attention to the following provisions when confirming the project cost or having a cost dispute:

I. Project Cost Management Organization Shanghai Construction Project Quota Management Station is the competent department of project cost management in this Municipality, and is responsible for the project cost management within this Municipality; Various engineering cost consulting institutions in the society are responsible for the valuation and evaluation of engineering price consulting; Shanghai construction engineering quota management station has the functions of supervision, inspection and management for engineering cost consulting institutions.

Second, the expression of project cost

1, fixed cost. Refers to the project cost that will not be adjusted due to market price changes during the project implementation. When determining the fixed fee, the price risk factor should be considered in advance, and the scope of the fixed fee should be clearly stipulated in the contract.

2. Adjustable cost. Refers to the project cost that can be adjusted with the price change in the process of project implementation. The adjustment scope and calculation method should be agreed in the terms of the contract in advance.

3. Project cost plus expense cost. This means that the current budget quota cannot be directly applied to the project. When calculating the project cost, we can refer to the current project valuation basis and method to calculate the project cost, and the remuneration will be determined by both parties through consultation (or bidding) based on the project cost.

Three. Confirmation method of project cost According to the provisions of the bidding management department of this Municipality, the project cost shall be confirmed in the following ways for greening planting projects:

1, 1 10,000 yuan greening project, the owner shall go through the filing formalities at the bidding management department of this municipality, and determine the project cost and contractor through bidding.

2, 50 ~ 1 10,000 yuan of greening projects, the owner should go through the registration formalities in the landscaping sub-center of the Municipal Construction Engineering Trading Center to determine the project cost and contractors.

3. The greening project of less than 500,000 yuan can be negotiated by the owner and the contractor, and the project cost can be negotiated with the contractor.

(twelve) the problems that should be paid attention to when the greening project is completed.

A greening construction project from budget preparation, negotiation, cost confirmation to contract signing is only the preparatory work of the project. After the project is completed, it will go through a difficult implementation and operation stage before the final cost of the project can be formally prepared. After the audit, as the basis for both parties to settle the project cost, the following issues should be paid attention to when preparing the final settlement of the greening project.

(a) the preparation of the project completion settlement, in the case of the same personnel, should be completed by the original construction drawing budget of the construction unit.

(2) Although the compilation of project completion settlement is carried out after the completion of the project, its data collection should run through the whole construction process without interruption.

(3) Data collection shall be carried out on the basis of strictly fulfilling the terms of the construction contract.

1. For fixed-cost contracts, in addition to saving normal expenses, attention should also be paid to project costs and data collection outside the scope of fixed costs.

2. For adjustable cost contracts, we should pay attention to the changes of adjustable price range and market conditions, and collect reliable original data and price basis in time so as to make reasonable adjustments during settlement.

3. For the cost plus fee contract, whether the cost expenditure conforms to the terms of the contract, and paying attention to the collection of the rationality and reliability basis of the cost expenditure is conducive to the smooth settlement of the project.

4. In addition, if there are construction measures, safety measures, claims, etc. in the contract, information should be collected and signed in time to ensure the smooth progress of construction and the conditions for reasonable recovery of project expenditure funds.

(four) the preparation of completion settlement, there are generally two methods:

1. For projects that have not changed much during the project implementation, based on the original construction drawing contract cost, according to the pricing method stipulated in the contract, and compared with the original data, make corresponding account increase or decrease, make appropriate adjustments, and finally use it as the cost settlement method for completion settlement. This method is widely used in greening and planting projects.

2. In the process of project implementation, the projects that have changed greatly must be redrawn according to the design change data. On the basis of the as-built drawings approved by both parties, the project is recalculated according to relevant data, and the settlement book of the project completion cost is compiled. This method has high accuracy, but it is time-consuming and labor-intensive, which often affects the timely recovery of project funds. For greening planting projects, this kind of situation is relatively rare, and this method is rarely used.
