Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidding method used when a primary contractor who has made a successful bid for a public works or private works ordered by a country, a prefecture or a municipal government or a material used for the same is further outsourced to a subcontractor. And a recording medium used for the same,
It is about the program.

[0002]

2. Description of the Related Art Conventionally, in public works of the national and prefectural governments, for example, one or more major civil engineering contractors (general contractors) authorized by the national or prefectural government make bids by bidding and bidding sponsored by the national and prefectural governments. It is often difficult for the main contractor who has won the public works to carry out all the public works in-house.For example, the revetment concrete works, slope greening works, bridge works, etc. were also approved by the government or prefecture. Outsource to multiple subcontractors. or,
General materials, such as concrete secondary products such as U-shaped grooves, gravel, trees, etc., required for each construction work have a business relationship with the main contractor, and can be ordered from a material distributor that is also licensed by the country or prefecture. Many.

[0003] However, public works that have been bidding by the prime contractor are generally constructed without bidding between the prime contractor and the subcontractor. Since the so-called convoy system that exists in the construction industry is adopted, despite the intense price competition in the state of the economic recession in recent years, we ignore the cost and order it to a contractor, a contractor It is inevitable that cost reduction is difficult. Even if a foreign-affiliated contractor makes a successful bid, it is difficult to carry out construction work because of the convoy system, and the criticism that foreign-affiliated companies have narrow doors after all is not solved. In some cases, a subcontractor must take orders at a low cost, ignoring profits at the will of the prime contractor. Furthermore, despite the fact that the stock of the material is large and that it is desired to dispose of it as soon as possible, it often happens that orders cannot be received. Therefore, it is necessary for the salesperson to spend a long time promoting sales in order to sell the material. Cannot be reduced.

[0004] The above problem can be solved by the prime contractor making a general auction to the subcontractor, for example, as performed in the perishables market.

[0005]

However, since the auction bidding requires that the bidding staff of the subcontractor be seconded to the main contractor, the first problem is that it takes a long time and labor costs are high. is there.

[0006] In addition, a trader who is qualified to participate in a bid is selected from traders previously approved by public institutions such as the government or a prefecture, and the winning bidder is determined based on the bid price of the designated trader. Had become. For this reason, only the bidding price is emphasized, and a successful bid is made without reflecting the rating evaluation, the ability of the engineer in charge, the past construction results, the safety level, the new technology, etc. that differ for each contractor. There is a second problem that it is difficult to select an appropriate trader according to the type of the contractor.

At the auction site, the main contractor and the subcontractor face each other, and the third problem is that it is difficult to set an appropriate bid price and order construction work because of the relationship between the contractors and the human relationship. is there.

It is conceivable to set up a bidding intermediary for mediating the bidding client and the bidding participants. However, since the intermediary must come and go at the auction site, the labor cost is further increased. Further, since the bid requester and the bid participant can still be specified, there is a problem in setting an appropriate bid price, and the third problem described above is not solved.

Further, there is a fourth problem that even if the subcontractor wins the auction and wins the construction, the former contractor may be required to change the contract price at a later date and may be sometimes canceled.

[0010] In the civil engineering and construction business, which is not a public business, the primary contractor is divided into a plurality of subcontractors and places an order or an estimate is obtained from the subcontractor. The third problem described above occurs.

It is an object of the present invention to provide a bidding method capable of appropriately setting an order and setting a bid price in consideration of factors other than the bid price.

[0012] A second object of the present invention is to solve the third problem in addition to the first object, to provide a connection between the prime contractor and the subcontractor, and to prevent the public relations from being affected by the human relationship between the persons in charge. Another object of the present invention is to provide a bidding method capable of appropriately ordering a private business and materials used therein and setting a bid price.

A third object of the present invention is to solve the fourth problem of the prior art in addition to the first object, and to request a subcontractor to change a contract price from a main contractor, An object of the present invention is to provide a bidding method that can eliminate the possibility of being canceled.

At step S371 in FIG. 3, the bid price of each bidder is read, and
At 372, the engineer code number is read. Table 1 shows the bid price and the engineer code number of each designated participant.

[0065]

[Table 1] Next, in step S373, an evaluation coefficient k by which the bid price is multiplied is calculated. This calculation method will be described below.

The evaluation coefficient k is calculated based on the rating evaluation points of the auction participants, the engineer in charge, the performance evaluation points, the safety evaluation points, and the new technology evaluation points. That is, the evaluation coefficient k is obtained by dividing the actual evaluation points into E1x, E2x, E3x,
E4x and E5x, a reference point E1 serving as a reference for each evaluation point
Assuming that a total reference point obtained by integrating c, E2c, E3c, E4c, and E5c is Et, and a constant is R, it can be obtained by the following equation.

K = ｛Et− (E1x + E2x + E3x +
... ENx)｝ ÷ R｝ ÷ Et The constant R is set in the range of 2 to Et so that the evaluation coefficient k is in the range of 0.5 to 1.0.

By the way, the bid price and each reference point E1
The respective ratios of c, E2c, E3c, E4c, and E5c are input and set in advance on the evaluation rate input form 18 as shown in FIG. This evaluation rate input form 18
Is provided with an industry selection field 181, and one of the various types of industries shown in FIG. 6 is selectively displayed. For the selected specific industry, the bid price evaluation rate 182, the rating evaluation rate 183, the performance evaluation rate 184,
The assigned engineer evaluation rate 185, the safety evaluation rate 186, and the new technology evaluation rate 187 are individually input and set. In this embodiment, each of the reference points E1c, E2c, E3c,

14 is read from the data recorded in the information file. That is, the rating evaluation points of the bid participants are created based on a method of calculating the score (Y) of the business examination (management matter examination). According to the example of the judging process, when the items and numerical values which are the basis of the management content calculation are determined as shown in Table 2, the score (Y) regarding the management is calculated as shown in Table 3.

[0070]

[Table 2]

[0071]

[Table 3] Assuming that the above score (Y) is 835 and the highest score of the current score (Y) is 1600, the rating score E1X = Ｘ835 ×
200｝ ÷ 1600 = 104. Therefore, it is recorded as a rating evaluation point E1x @ 104/200.

In the technician evaluation information file, each technician is converted into a code number, and the evaluation points of each technician are recorded, for example, as 350/500. Interviewers evaluate the evaluation points by interviewing the person in charge of the ordering party (general contractor) after construction and inspecting the workmanship of the construction site. ing.

In the performance evaluation information file, the successful bid price of the construction contracted by the auction participant since the start of the operation of the present system is recorded as a score, for example, 400/500. In this scoring, the highest cumulative successful bid price of a single bidder is set to 500, and the cumulative successful bid prices of other bidders are calculated in proportion.

Further, the safety evaluation points are recorded in advance, such as 200/300, based on past personal injury or property damage accidents. In the new technology evaluation information file, for example, 25
0/300 is recorded in advance.

Therefore, in step S373 described above,
Based on the calculation formula of the evaluation coefficient k, each bidder designated participant P3
Are calculated respectively. The evaluation coefficient of each nominated participant is, for example, as shown in Table 4.

[0076]

[Table 4] Next, in step S374, the evaluation coefficients kc and k are added to the bid price.
A corrected bid price is calculated by multiplying b, kd, and ka. Table 5 shows the corrected bid prices.

[0077]

[Table 5] In the next step S375, the corrected bid prices are sorted in the order of the lowest price, as shown in Table 6.

[0078]

[Table 6] Next, the corrected bid prices sorted in step S376 are displayed on the screen as a corrected bid price display form 19 as shown in FIG. In this corrected bid price display form 19, in step S377, the designated participant of the lowest corrected bid price is designated by, for example, a cursor, and the successful bidder determination button 19 is set.
By clicking 1, the successful bidder can be determined. In conjunction with this, the anonymous state is released as shown in step S378. By this click, the auction result display form 20 shown in FIG. 16 appears (see step S379).

50 million yen "is read out and displayed as it is. Further, the successful bidder (successful bidder participant P3) 203 that has been anonymous is read from the storage device 114 and automatically displayed as a specific name.

As described above, the names such as the anonymous company names of the bid requester and the bid designated participant are stored in the bid broker server 11.
Will be released after the end of the auction and will be released to the parties concerned. For this cancellation, for example, a button (not shown) for canceling the bidder anonymity and a button (not shown) for canceling the bidder anonymity may be clicked on the corrected bid price display form 19 shown in FIG. 15, for example. .

In the bid ranking 204 shown in FIG. 16, for example, the bid prices and the corrected bid prices of all the bidders are sorted and displayed. Further, step S38 in FIG.
When the transmission button 206 shown in FIG. 16 is pressed, the bid result is transmitted to the bid client P2, the front server 14, and each designated participant P3 via the computer network NT. Here, the work of the auction intermediary P1 ends.

On the other hand, the bidding client P2 transmits the bidding result received in step S39 to the bidding result form 2 shown in FIG.
0 'is displayed to confirm the successful bidder (step S40), and the result of the auction is printed (step S41), and the operation of the client client 12 is terminated. In the case of a plurality of participant clients 13, each of them is received (step S4
2) The auction result is confirmed (step S43), and the auction result is printed (step S44). Front server 1
In step 4, the received auction result is confirmed (step S45), and the auction result is printed.

The front server 14 invites the bidder and the successful bidder to join them together, assists them in fulfilling the contract for construction, and ends a series of bids (step S46).
The bidding participant enters into a contract with the bidding client regarding the bid object that has been awarded in the presence of the bidding intermediary, and pays a penalty to the bidding intermediary in the event of violation.

The auction intermediary P1 is assigned to all the nominated participants P
If the difference between the average bid price of No. 3 and the successful bid price is large, an offer is made to correct the average price and make a successful bid. In addition,
The probability of a conflict occurring in the auction operation described above is extremely low. If this occurs, the nominated participant with the lower bid price will be the successful bidder.

According to the bidding method of the above embodiment, the following features can be obtained. (1) In the above embodiment, the corrected bid price is calculated by multiplying each bid price by the evaluation coefficient k, and the successful bidder is determined from the lowest price. For this reason, an appropriate successful bidder can be selected as compared with determining the successful bidder based only on the bid price.

(2) Prior to the bidding process, a bidder who can participate in the bid is selected from a regional viewpoint and a trader who has a track record suitable for the desired price. For this reason, it is possible to prevent an inappropriate trader from participating in the auction.

(3) A front server 14 is provided separately from the intermediary server 11, so that contract work is performed independently. For this reason, it is possible to prevent adverse effects due to adhesion due to the connection between the client P2 and the designated bidder P3.

(4) In the above embodiment, the bidder P2
Is kept anonymous so that the designated participant P3 is not aware of it, and the designated participant P3 is kept anonymous so as not to be known to the bid client P2 and other designated participants P3, and the bid designated participant P3 Made a bid. For this reason, it is possible to set an appropriate order for construction and set a bid price without being affected by the human relationship between the persons in charge, because of the relationship between the main contractor and the subcontractor and between the subcontractors.

(5) In the above-mentioned embodiment, since the bidding is performed via the computer network NT, labor costs are reduced, and closed information such as public works is disclosed to companies other than the nominated company. be able to.

(6) In the above-described embodiment, the auction intermediary server 11 preliminarily swears to the auction client or the auction participant about sanctions when the auction client or the auction participant fails to fulfill the promise with respect to the auction result. After transmitting the data in the form of a letter and receiving both the pledge confirmation data, the bidding operation is executed. For this reason, it is possible to reduce the possibility that the subcontractor is requested or changed by the main contractor to change the contract price.

The above embodiment may be modified as follows. A file that only the designated trader (member) can access the bid broker server 11 may be provided exclusively for the bid broker server 11 to prevent entry from an unspecified number of traders. In this case, the bid intermediary server 11
It is conceivable to prepare a special keyword for accessing this file and give it to a designated bidder in advance.

[0092] In the case where the result of the auction of the membership system may be disclosed to a large number of unspecified traders, the home page on which the result of the auction is recorded is disclosed on the auction intermediary server 11 together with the address (URL) on, for example, a newspaper. I do.

In the above embodiment, the specific names of the bid requester and the designated bidder are made public after the auction ends. However, even before the end of the auction, the auction bidding information D2 is transmitted to the auction agent server. After transmission to No. 11, all the designated participants P3 may not be able to correct the bid information D2, for example, after the auction bid deadline time.

Therefore, when the bidding operation time zone is set after the elapse of the bidding reception time zone, when the bidding operation time is set, the mediator P1 inputs the specific names of the client P2 and the designated participant P3 in the bidding mediator server 11. It may be made public.

The bid designated participants P3 may make a bid without anonymizing each other even during the bid reception time zone. In addition, the client P2 determines that the intermediary P1 can know the specific name of the designated participant P3.
2 may be transmitted.

In the above embodiment, the public works are embodied. However, the private works are carried out by setting a designated bidder in advance, or in a form in which an unspecified number of people are allowed to participate in the bid. Is also good.

In the above-described embodiment, the auctions of various constructions are embodied. However, the auction method may be embodied for various materials such as civil engineering and construction used for them. In this case, using the material name, material number and required quantity as the material information created by the bid client, and using the material name and material number that the designated bidder can sell to the bid client as bid auction information, Auction will be conducted in the same way as the construction for the price and delivery quantity of the materials.

In step S24 of FIG. 2, if the participant P1 does not appear to the end even if the intermediary P1 sends an e-mail to the participant client 13 and sends the e-mail to the participant client 13, the agent P1 informs each participant that this is the case. The notification may be made to the person via the computer network NT to urge the person to bid again.

In the case of using the Internet, even if the bidding information D2 is transmitted before the closing time (reception time zone), it may not reach the bidding agent server 11 of the bidding agent P1 due to some factors. By providing a form that allows the bidding participant to confirm the transmission contents, the bidding participant can transmit the bidding contents to the bidding agent server 1
It is desirable to arrive at the deadline time of 1.

○ Target information D1 (public construction information D1a)
4 and 5, a button is provided on the screen of FIGS. 4 and 5, and by clicking the button, another screen of the browser is displayed so that the target information D1 can be output to a plotter, a printer, a CAD (CAD) system, or the like. Good.
