1) bill of quantities valuation is an equal competition platform provided by the government for construction enterprises, which enables different enterprises to bid independently on the basis of their own strength and the same engineering quantity, fully embodies the advantages of enterprises, standardizes the competition order, ensures the construction quality, and is an effective way for the government to strengthen macro management and change its work functions.
2) It can meet the needs of competition under the condition of market economy, effectively avoid the double calculation of tenderers and bidders in engineering quantities, and standardize the pricing behavior of all parties in engineering construction. At the same time, it promotes the formulation of bidders' enterprise quota and the accumulation of market basic data, which is conducive to improving the efficiency of engineering measurement, enhancing the management ability of enterprises and promoting the perfection and development of the construction market information system. 3) In the global market environment of the construction industry, only by constantly improving the bill of quantities pricing system, reasonably sharing risks, injecting scientific pricing management mode, giving full play to the subjective initiative of all parties in the construction industry, controlling the process, reducing waste and disputes, can we constantly adapt to the increasingly fierce domestic and international competition and create good conditions for China's construction market to be in line with international standards.
2 at this stage of China's implementation of the bill of quantities valuation problems
1)20 13 has solved the current EPC (design-procurement-construction) contract mode well, but with the increase of BT (financing-design-procurement-construction-transfer), BOT (construction-operation-transfer), TOT and other contract modes, the current 20650. 2) The project cost information is distorted. It is difficult to collect, release information seriously lags behind, can't keep up with market changes, prices are distorted, and the law of value "fails", which can't meet the actual needs of engineering management; The inconsistency between the fixed labor price and the actual wage in the market is likely to lead to disputes and disputes in engineering measurement payment.
3) At present, China's credit system is lacking, the project guarantee system and the project insurance system cannot be effectively implemented, and there are unequal contracts. The confirmation, adjustment, payment and claim for change of the project price cannot be solved in time and effectively. However, the construction projects in China's construction market have the characteristics of large investment, long cycle and complex technical requirements. The parties involved in the construction are not aware of risk prevention, and they cannot properly solve risk measures, so contract disputes often occur.
4) The development level of construction enterprises is uneven, and only a few enterprises have enterprise quotas that reflect their own strength. The list lacks the basis of group pricing, and the adopted regional or industry budget quotas are not supplemented and revised in time, which brings great difficulties to the tender offer, making the implementation of the bill of quantities specious and unable to fully reflect the advantages of the bill of quantities pricing. 5) China's cost management institutions started late, the foundation is poor, the relevant cost consulting policies and regulations are not completely matched, and the engineering cost consulting industry has not been understood and accepted in society. There is a serious shortage of engineering cost practitioners who know engineering technology, economy, management and law, and have rich practical experience and good professional ethics. The strength of engineering cost practitioners and engineering cost consulting enterprises is far from the requirements of globalization of the construction market, and the overall strength needs to be improved.
3 Development direction of bill of quantities valuation
1) bill of quantities valuation fully reflects the fair, open and just competition in the construction industry under the market economy system, and is the core content of the construction market operation. Combining the international and domestic EPC mode, DB mode, DBO mode, turn-key mode, parallel contracting mode, consortium contracting mode, cooperation mode, CM mode, Partnering mode, BOT mode, PPP mode, TOT mode and PFI mode, we will vigorously develop the bill of quantities pricing mode to adapt to the ever-changing contract management system and create favorable conditions for the construction industry to avoid corruption and change, sunshine management and connect with the international construction market.
2) Establish and improve the project guarantee and insurance system, adopt the form of performance guarantee and bank guarantee, and introduce a third-party guarantor. In the construction project, through the contractor's bid guarantee, performance guarantee, material and mobilization advance payment guarantee, migrant workers' wage payment guarantee, quality retention guarantee, defect warranty guarantee, owner's payment guarantee, etc., the supervision function is fulfilled, and in order to avoid taking responsibility for breach of contract, the construction parties are urged to keep their promises. Participate in market competition with quality and integrity, avoid disorderly and vicious competition, fully prevent and decompose some risks of all parties involved in the project, and ensure that all stages of the project can be carried out normally.
3) In order to promote the smooth development of bill of quantities valuation, we should constantly strengthen and improve information management, establish and improve the database, give full play to the principle of "standardized, effective, timely and efficient processing" of engineering cost information, and implement dynamic management. Prepare fixed assets investment plan, investment estimate, preliminary design estimate, construction drawing budget and various quotas, determine the tender control price and tender quotation, conduct production capacity analysis, cost analysis and technical and economic analysis on the construction unit, determine the price adjustment coefficient, and study the law of project cost change.
4) Vigorously advocate powerful construction enterprises, and formulate enterprise quotas that can reflect their own strength, adapt to the management mode of bill of quantities valuation, and dare to participate in international and domestic market competition. Strengthen the management of the practice access system for engineering cost institutions and employees, and vigorously cultivate employees with engineering technology, economy, humanistic skills, management legal knowledge and rich practical experience, as well as healthy psychology and physique, law-abiding, honest and self-disciplined, honest and trustworthy; Vigorously advocate the establishment of cost consulting institutions with independent practice ability, exquisite business and good professional ethics in accordance with the principle of "fairness, justice and integrity". In a word, with the internationalization of construction project management, bill of quantities valuation method is the most effective bridge to connect with international engineering practice. Only by constantly improving the valuation standard of bill of quantities can we control the whole process of project bidding, bidding quotation, contract agreement, price payment and final accounts, and promote the healthy and rapid development of China's construction market.
