How to prepare and determine the tender price of engineering construction projects

According to China's national conditions and the status quo of the construction market, in a certain period of time, China's engineering construction project bidding activities in the preparation and determination of the bidding is still an important content and task. Set the bottom of the bidding, is still an effective measure to control the cost of the project, to prevent improper means of bidding price is too low to grab the bid. Engineering construction project tender is the bidder of the tender project "internal control" budget, that is, in the market under competitive conditions for the implementation of the project cost prediction, is the bidder for bidding needs to grasp the important price information, is the correct judgment and evaluation of the reasonableness of the bidder's tender offer and the reliability of the important reference basis. Need according to the bidding documents, drawings, relevant regulations, bidding for the specific circumstances of the project to prepare and determine the tender. First, the preparation and determination of the principle of engineering construction project bidding According to set the purpose and role of the bidding, the preparation and determination of the bidding for engineering construction projects should follow the "abide by the rules, scientific and fair, according to the local conditions, the survival of the fittest" principle. Specifically can be explained as follows: comply with the rules: the preparation and determination of engineering construction project bidding first of all should comply with the provisions of the tender documents, because the tender documents is the preparation and determination of the legal basis of the bidding documents, tender documents in the provisions of the bidder needs to be considered, the bidding should be embodied in the base. Secondly, it should comply with the provisions of the relevant national cost management, the preparation of the bidding shall not exceed the approved design estimate or the bidder to prepare the implementation of the estimated budget. Further, the specific regulations issued by the competent authorities on the preparation of the tender base and the relevant regulations on the management of the construction market shall be complied with. Science and fairness: It should carefully analyze and study, ensure the use of reasonable labor, materials, machinery quotas and basic prices and unit prices of works, so that the preparation of the tender fully reflects the science, authenticity, reasonableness and completeness. Tender preparation should be from the overall concept, fully reflect, take into account the interests of the state and the bidder and the bidder, reflecting both the reasonable cost of construction, but also reflect the bidder's management costs and reasonable profits, as well as national taxes, prices and other policy factors. Adapt to local conditions: in the socialist market economy, the same product in different conditions, different geographical areas will have different prices, and the preparation of the tender should be combined with the objective reality of the construction site of the construction project and the project level, characteristics, types and other specific circumstances, and careful understanding and study of the construction site of the engineering and construction content, construction organization and design, geological conditions, transportation conditions, materials and water and electricity supply related situations The company shall carefully understand and study the construction content, construction organization design, geological conditions, transportation conditions, materials, water and electricity supply, local policies and regulations, price levels and other constraints. Fully study the relevant technical and commercial terms of bidding documents, design drawings and relevant technical specifications. Make the preparation of the tender can be realistic and objective to reflect the specific construction project, specific construction environment, specific timely price and other relevant specific circumstances, and strive to be realistic. The best and the worst: the preparation of the tender should follow and implement the "control volume, guide price, competition fee" of the cost management reform guiding ideology. Preparation of the bidding used in the use of artificial, materials, machinery quota and the relevant rate standards, fees, prices, etc. should reflect the average level of society, reflecting the amount of social labor necessary, that is, the bidding is a construction product of the average social price (or average price of the construction market), only lower than the amount of social labor necessary for bidding can be accepted by the community (construction market) or the bidder. Preparation of the tender should also fully grasp the pulse of the market, master market information, adapt to market conditions, under the premise of ensuring the quality of the project, and strive to create a benign and fair competition, the survival of the fittest bidding environment. Second, the engineering construction project bidding method 1. Estimates decomposition method: the approved preliminary design estimates in accordance with the content of the bidding project is divided into corresponding decomposition, and then measured the appropriate percentage of the reduction is determined. Commonly used in single, simple construction projects. 2. Quota calculation method: that is, according to the bidding documents given the bill of quantities, according to the current provisions of the relevant industry to complete the unit of product man, machine, material quotas and analyzed the corresponding base price determined by the study and calculated the base price. Applicable to all types of projects. 3. Process analysis method: that is, according to the bidding documents given a project volume, analysis to determine the completion of the project processes required for labor, construction equipment, working hours and the corresponding base price and calculate the base price. Applicable to mechanical equipment construction projects. 4. Empirical estimation method: the bidding staff according to their own accumulated experience and a large number of similar projects cost data, with simple analogies, analysis and estimation methods to determine the project unit price directly. Commonly used in the price of the bidding does not have much impact on minor construction projects. 5. Combination of methods: the above methods are used jointly in the same engineering construction project bidding. Third, the rational preparation of engineering construction project bidding a few key issues 1. effectively focus on the project site investigation and research. Should take the initiative to collect, master a large amount of first-hand relevant information, analyze and determine the appropriate, realistic price and unit price of a variety of basic engineering to ensure that the compilation of a reasonable tender. 2. Pay attention to the selection of construction machinery and equipment. According to the characteristics of the project and construction conditions should be carefully analyzed, a reasonable choice, and strive to be economical and practical, advanced and efficient, do not copy, detached from the actual, otherwise it will directly lead to the selection of the quota and unit price analysis of the deviation. 3. Pay attention to the construction organization design. Should be through a detailed technical and economic comparison and then determine the relevant construction program, the construction of the general layout, progress control network diagrams, transportation programs, etc., in order to facilitate the selection of the construction organization design is safe, reliable, scientific and reasonable, which is the premise of the preparation of a scientifically sound bidding. 4. Effectively focus on the calculation of the lump sum price of the entries. The bill of quantities often have some items do not give the amount of work, require cost staff to fill in a lump sum price, such as temporary works. Should be based on the bidding documents and construction requirements and other specific circumstances, in-depth study of its project composition and work content, in order to avoid omissions under the premise of reasonable pricing. Fourth, to determine the engineering construction project bid evaluation methods At present, China's construction market bidding activities often used to determine the engineering construction project bid evaluation methods are mainly the following: 1. Preparation of the bidding method. That is, the bidder's organization to prepare the bid as the evaluation of the bid. 2. Quotation average method. That is, all or part of the bidder's bidding price as the average of the evaluation of the tender base. 3. Combined plus, weighting method. That is, the bidder's organization to prepare the bidding value and the bidder's bidding price of the average weighted average as the evaluation of the bidding price. Usually the bidder's organization to prepare the bidding value of the weight of 50% - 70%. 4. Shortlisting average method. That is, the bidder's organization to delineate the value of the bidder's preparation of the bidding value of the upper and lower range of effective bidding to enter the effective bidding range of the average bidder's tender price as the evaluation of the bidding price. V. Determine the engineering construction project bid evaluation should pay attention to the dam 1. Determine the engineering construction project bid evaluation, first of all, should ensure that the bidding can be set to maximize the quality of construction and construction period to meet the requirements of the bidding, that is, the bidding should be set with the bidding documents related to the quality of construction and construction period of the technical terms and conditions of the technical specifications to adapt to the specific requirements. Because the quality, duration, cost is the construction of three complementary, mutually complementary, mutual constraints, the main control factors, the three-legged state of the loss of any one party's control, will lead to the other two parties to produce deviation. 2. Regardless of the method to determine the bidding evaluation of engineering construction projects, bidders should be in accordance with the laws and rules of the market economy, the reasonable cost of engineering construction projects for the necessary analysis and prediction, to do a good job, know your enemy and know yourself, and must not fight unprepared for the battle. Both to avoid the set bidding too much higher than the reasonable cost, resulting in unnecessary economic losses, damage to the state, the interests of the bidder, but also to avoid the set bidding lower than the reasonable cost, resulting in unhealthy competition, damage to the interests of the bidders, and ultimately affect the normal, orderly and healthy implementation of the construction project.
