Supervision and bidding of water conservancy construction projects?

Bidding is a transaction method adopted in the contracting of engineering construction projects under the condition of market economy. Water conservancy project supervision refers to water conservancy projects, and the units that need construction projects entrust corresponding water conservancy project supervision enterprises, according to relevant laws, regulations and standards, water conservancy project entrusted supervision contracts, construction documents approved by relevant construction contracts and project management activities. The premise of water conservancy project implementation supervision is the entrustment of the construction unit. The main actor of water conservancy project management is the water conservancy project supervision enterprise, and the main participants of water conservancy project supervision activities are social supervision units, construction units and contractors.

Under the condition of socialist market economy, most water conservancy projects are invested by the state, and the construction of water conservancy projects is related to the safety of life and property of the country and people, and to the smooth progress of reform, development and modernization. On June 5438+1 October1day, 2002, in order to ensure the project quality and promote the realization of the investment benefit goal, the Regulations on the Management of Bidding for Water Conservancy Construction Projects was implemented. Through years of practical experience, we should pay attention to the following points in the bidding process.

1, familiar with the laws and regulations of the project subject to tender.

If you want to win the bid, you must first understand the bidding procedure. Generally speaking, bidding needs to go through the procedures of bidding, tendering, bid opening, bid evaluation and calibration. Existing bidders should also be familiar with the Bidding Law, the Regulations on Bidding Management of Water Conservancy Construction Projects and the relevant regulations of the Ministry of Water Resources and Tianjin. It is a necessary condition for bidding to clarify the illegal behavior of bidders and their legal responsibilities.

2, familiar with the tender documents

The tender documents stipulate the responsibilities and rights of the contractor, which is the key to do a good job in bidding. After purchasing the tender, we must attach great importance to it, take the time to carefully read and study the tender documents, and pay special attention to the substantive requirements and conditions in the tender documents. According to the law, the bidder fails to respond to one of the substantive requirements and conditions in the tender documents, such as the price of the project subject to tender, the technical specifications of the project, the main terms of the contract, etc. , which will lead to the rejection of the bid. Therefore, it is necessary to analyze and judge the bidding documents one by one, find out all the substantive requirements and conditions, and study them one by one.

3. Conduct field research.

In order to be familiar with the general situation of the project, it is necessary to conduct on-site investigation. The investigation of the project location should understand the natural conditions, construction conditions, public security situation, social service facilities and conditions. In particular, the scope of land use, topography, landform, elevation, site, roads, passages, machines and tools, material stacking, electricity consumption, water use, construction drainage and other aspects of the project site are the basis for doing a good job in construction organization.

4. Attend the pre-bid meeting

The pre-bid meeting is an opportunity for all bidders to answer questions, which is conducive to deepening the understanding of the bidding documents. Before attending the pre-bid meeting, the bidding documents should be thoroughly studied in advance, and all kinds of problems found in the research process should be sorted into written documents and submitted to the bidding unit. When attending the pre-bid meeting, special attention should be paid to: (1) If there are doubts or ambiguities about the project content, contract terms, technical terms, drawings, etc., explanations should be given, but no modification or change scheme is allowed. (2) The tenderee's or consulting engineer's answers to all questions at the pre-bid meeting should be sent in written form and become an integral part of the tender documents. Bidders can't just rely on oral replies to prepare their bidding documents.

5, the preparation of construction organization design

Construction organization design is a technical measure to meet the design intent. Technical measures have economic guarantee, and the economy of construction projects is engineering investment. It can be seen that the construction organization design covers organizational measures, technical measures and economic measures. The construction organization design mainly includes: the personnel organization of the project management department, the project construction plan, the construction progress plan, the quality assurance measures, the safety production measures, etc. Project construction scheme is the key. According to the characteristics of the construction stage, it is the stage with the largest capital investment. The construction period of the special open channel protection project for Luanhe River diversion is generally 20 days, and the longest is not more than 30 days. The construction period is short and the task is heavy, and the project capital investment exceeds one million. Therefore, how to work out the construction organization design and make it scientific, reasonable and feasible is particularly important. Therefore, we must grasp the most prominent characteristics of the construction stage and work out the construction organization design. Please note the following points:

5. 1 Familiar with the general situation of the project

Because all kinds of projects have their own characteristics, each construction project has a specific purpose, so there are different structures, shapes and decorations, different volumes, areas, technologies and materials. Even for construction projects with the same purpose, there are differences in technical level, building grade and building standard. And influenced by natural conditions such as climate, geology, earthquake and hydrology, we must be familiar with the general situation of the project and make full preparations.

5.2 When compiling the construction organization design, the division of labor should be clear, so that the whole process of compiling standards can proceed as planned.

In the process of compiling the construction organization design, we should grasp the key points, highlight the word "organization", and make careful arrangements for manpower, material resources and methods, stages and the whole process, before and after. In the construction, make the work substantial and concrete, which is not only conducive to improving the construction period and quality of the project, but also conducive to reducing the project cost. Only by compiling the construction organization design can we ensure the optimal allocation of resources, reasonable construction progress and suitable construction technology, eliminate all kinds of interference and enhance the competitiveness of bidding.

6, tender offer

Determining the best quotation is one of the keys to improve the bidding ability. Under the optimal quotation conditions, the construction contractor not only has the opportunity to win the bid, but also can obtain considerable profits. When bidding, consider the following aspects.

6. 1 Choose the quota carefully

When quoting a project, the correctness of quota analysis and selection is one of the key factors that affect the quotation level and the success or failure of bidding, so we should be very cautious. Bidders should choose the quota according to the relevant information in the bidding documents, especially the technical specifications, and also consider the actual situation at that time, such as engineering conditions, natural climate conditions, workers' quality, mechanical level, engineering technical regulations, engineering supervision and other factors.

6.2 Understand the situation of competitors

Theoretically, the quotations of all bidders should be basically similar, and the differences mainly lie in the expected surplus, construction plan, management expenses and local advantages. Therefore, when there are many competitors and the competitiveness is strong, the tender offer should be reduced appropriately.

6.3 Pay attention to the description of bid evaluation standards and methods in the bidding documents.

Generally speaking, the quotation of a project evaluated by comprehensive evaluation method should not be too low, and the closer it is to the pre-tender estimate, the better. For the project evaluated by the lowest tender price method, the quotation should be as low as possible on the premise that it is not lower than the cost price. However, it should be noted that the comprehensive unit price of each single project should be balanced to avoid losing the chance of winning the bid because the unit price of the project is too low and the quotation is adjusted after evaluation.

6.4 Pay attention to the difficulty of engineering construction.

In addition, attention should be paid to the binding and typesetting of tenders. Some bidders think this is a small problem and have not paid enough attention to it. In fact, it is often these details that affect the overall situation and lead to a total loss.

The bidding documents shall be encapsulated according to the requirements of the bidding documents, and the external seal shall not have any seal or trace showing the bidder, indicating that it shall not be opened before the bid opening on a certain day of a certain year; The bidding documents shall meet the requirements of the bidding documents, and the cover shall be stamped with the seals of "original" and "copy"; "Original" conforms to the requirements of the tender documents. If it needs to be signed and sealed, it shall be signed and sealed by the legal agent or entrusted agent. Copies can be used; The tenders shall be numbered in sequence, and each page of the bill of quantities shall be stamped with the official seal and signed by the legal representative or entrusted agent; The signature of the power of attorney in the tender shall be signed by the legal representative or entrusted agent, and shall be signed by the legal representative or entrusted agent; The tender shall be carefully filled in according to the format and requirements provided in the tender documents, and shall not be omitted or altered; The bid documents shall be protected from being altered. If there is any amendment, the entrusted agent shall sign the amendment. The pre-tender estimate preparation sequence shall be prepared according to the requirements of the tender documents.

In a word, the norms and systems of engineering construction bidding in China have been relatively perfect. Although supervision bidding has been launched, it is still much less than flag bidding, and there is no supervision bidding model. Supervision bidding's methods and evaluation criteria need to be further improved. In the future work, how to standardize and program the bidding activities of engineering supervision, build a more complete bidding decision-making system of engineering supervision, and make qualitative analysis and quantitative calculation of the problems encountered in practical work, so as to make the bidding decision more scientific remains to be studied.
