Keywords bidding and tendering equipment installation characteristics practice
The bidding and tendering activities of construction engineering equipment installation project is an important part of the bidding and tendering activities of construction engineering projects, it is accompanied by the development of the development of the bidding and tendering of construction engineering projects. Especially in recent years, the continuous development and improvement of engineering equipment technology, new technologies, new functions continue to appear, the investment in construction engineering equipment installation project investment ratio in engineering construction increases year by year, the number of equipment installation project bidding in the construction project is also increased year by year, the author combined with the recent years in the construction engineering equipment installation project bidding work of the practical experience of the bidding work on the construction engineering equipment installation project bidding The development of activities and characteristics of the following discussion:
I, the development of construction equipment installation project bidding
From the founding of the country until the end of the seventy years, our country has been copied from the Soviet Union's highly planned economic system, the various departments and units of the construction project and construction installation projects, are issued by the competent government departments in accordance with the plan directives, the equipment is a unified plan, the fixed-point production, the installation enterprise production, operation activities are all the same, and the installation of equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment, equipment and equipment. Installation enterprise production, business activities are arranged by the government authorities through administrative means.
In 1980, the State Council issued the "Provisional Provisions on the Development and Protection of Socialist Competition", for the first time, some of the production and construction projects suitable for contracting and business projects, can be a trial bidding method.
In 1983, the State Ministry of Urban and Rural Construction and Environmental Protection issued the "Trial Measures for Bidding and Tendering of Construction and Installation Projects", which laid the foundation for the implementation of the bidding and tendering system for China's construction and installation projects, and also opened up China's construction and equipment installation projects to implement the prelude to the bidding and tendering system.
In 1984, the State Planning Commission, the Ministry of Urban and Rural Construction and Environmental Protection jointly issued the "Interim Provisions on Tender Bidding for Construction Projects" (Planning Shi [1984] No. 2410), from the trial approach to the Interim Provisions, marking China's construction project bidding on the institutionalized track.
In 1992, the state promulgated the "Chinese People's **** and the State Bidding Law", which determines the legal status of bidding activities, marking China's construction project bidding into the legal system, procedural era.
Second, the characteristics of the construction project equipment installation project bidding
Construction project equipment installation project has the following characteristics:
1, equipment installation project variety
Housing construction project in the equipment installation project variety, the more common are: elevators, escalators, central air conditioning system, building intelligence system, water supply and drainage equipment, Fire fighting equipment, high and low voltage power distribution equipment.
2, the technical development of construction equipment projects fast
The development of housing projects is mainly reflected in the development of equipment. In the past, most of the housing projects are only three or four stories high, mostly brick structure, equipment installation only simple water supply and drainage system and civil power supply system, accounting for a small proportion of housing investment. With the development of the economy, people's material living standards continue to improve, the requirements of residential and office space also continue to improve, housing construction projects are not only higher and higher, advanced equipment and facilities have entered the housing project. Such as: elevators, escalators have become the main supporting projects of high-rise housing projects; central air-conditioning systems, building intelligence systems have become the main equipment for office and commercial buildings and gradually enter the ordinary residential building projects, it can be imagined that the new equipment will be with the continuous development of new technologies and the emergence of equipment bidding projects will continue to expand.
3, equipment installation project implementation program
Each equipment installation project due to the continuous development of technology, different technologies coexist in the situation, so that the equipment installation project implementation program.
For example: central air-conditioning system has a water-cooled centrifugal air-conditioning system, water-cooled screw machine central air-conditioning system, air-cooled heat pump central air-conditioning system, variable refrigerant flow air-conditioning system, ice-cooled central air-conditioning system.
Elevator equipment from the building is divided into a machine room and no machine room, which can be divided into a machine room with gears and no gears, no machine room can be divided into the upper host and the lower host; from the control is divided into the VVVF (voltage, frequency, speed) control, AC speed control, AC two-speed control. And new technologies and products are emerging again.
4, equipment tenders need to consider a number of factors, and different equipment need to consider different factors
Different types of construction equipment, its main technical parameters, the scope of the tender, manufacturing and acceptance standards, acceptance, after-sales service requirements are not the same.
such as water pumps, transformers and other equipment bidding, only need to consider the main technical parameters, selection of materials, supporting the requirements of the pieces, while the elevator bidding, in addition to consider the main technical parameters, selection of materials, supporting the pieces of factors to be considered in addition to the elevator's use of the function of the decorative, the civil construction of the supporting nature of the installation, the elevator's comfort parameter requirements, the failure rate, the commitment to after-sales service and other conditions.
5, equipment installation project bidding is different from the civil engineering bidding
Because of the formation process of equipment and construction products objectively there is a big difference in the process of formation, so the decision of the construction project equipment bidding and construction bidding is different, construction bidding requirements for the construction of building projects according to the construction design drawings of the construction of the bidding unit, according to the unified volume of quotations. And equipment bidding process, the design can only provide basic specifications, technical parameters, layout plans, the manufacturers in order to achieve the basic requirements set out in the bidding documents, its processing and manufacturing drawings, processing equipment, processing technology is different, processing of construction equipment completed the specific functions of construction engineering, performance configuration, quality, service life is also different, which results in the price of different brands of manufacturers of products Difference is huge, because the basic design requirements of the construction engineering equipment to meet the project there are different grades, high grade manufacturers of its materials, processing accuracy, processing technology, assembly level, the quality of purchased parts, the control system of the advanced, the stability of the performance of the equipment is relatively good, the future use of the process of quality and stability, high efficiency, low rate of repair. The only advantage of low-grade manufacturers, often cheap, high-end products and low-end product price difference.
Three, the practice of bidding and tendering activities for construction equipment installation projects
According to the characteristics of construction equipment installation projects, in the practice of bidding and tendering activities, should also be based on its particularity and construction projects are different.
1, in the process of preparation of bidding documents, the technical requirements of the bidding equipment, specifications parameters, functional requirements, after-sales service requirements, the main terms of the contract should be as clear as possible, so that the bidding products of various manufacturers as close as possible to the technical performance, so as to evaluate the bid.
2, taking into account the construction equipment bidding units from all over the country, the local bidding procedures and practices do not understand the local bidding, in the provisions of the bidding documents, try to avoid non-substantive reasons for the abolition of the bidding, and improve the efficiency of bidding.
3, construction equipment installation project bidding the most special is the evaluation method
Construction equipment installation project bidding using the low price winning method for some simple technology, mature technology equipment is more appropriate, but there is a certain technical content, the processing process requires certain requirements for the installation of equipment is not very suitable, because of the advanced technology and configuration, quality and performance of the stable, comprehensive function of the equipment Installation companies may not be able to win the bid because of the high price, and low-priced equipment can not fully achieve the desired technical qualifications.
The author believes that the use of comprehensive bid evaluation method is more reasonable, the key is to scientifically and rationally prepare the technical requirements of the tender documents. Reasonable setting of the technical bid and offer bid weight, because different types of equipment, the price gap between different manufacturers is not fixed, in setting the weight, that is, taking into account the reasonable competition between different manufacturers, but also to consider the technical advancement and the stability of the use.
4, construction equipment installation project bidding examples
The following is a commercial bank office building intelligent security system bidding documents and evaluation methods for some examples:
Intelligent security system is an important banking office equipment system, the requirements of the equipment has a very high degree of stability and good operation, so the project is bidding using a percentage of comprehensive scoring system, the commercial and technical bidding points. In the business bid and the technical bid on the distribution of the weight of the points focusing on technology, taking into account the business, the technical bid accounted for 60%, the business bid accounted for 40%. In the bidding documents require the bidder's bidding documents to provide the bidding price list and bidding list of goods, the system network to build the connection design program, construction program (installation and construction organization design), personnel training program, and require the bidder in the quality of the product's origin, product quality, service life, system delivery and use of the warranty time to make a commitment to the bidder on the arrival time of the equipment, installation and commissioning time, failure to arrive at the time of installation and commissioning, the time of arrival at the time of failure, the time of arrival at the time of installation and commissioning, In terms of service, the bidder is required to make a commitment to the arrival time of the equipment, installation and commissioning time, the shortest time to arrive at the site in case of failure, and the service after the expiration of the warranty period.
