Description

  The present invention relates to a construction material delivery management system, a delivery method, and a recording medium for a management program that enable efficiency and cost reduction of construction material delivery work to a construction site.

For example, a construction company that orders and sells wooden custom houses performs ordering, design, and construction supervision according to the following procedure. First, when a building is ordered from the owner, it is designed. In addition, select a construction shop and material manufacturer in charge of the construction area. Deliver the design drawings to the construction shop and ask the construction to discuss the specifications and construction schedule. The construction shop orders various materials necessary for construction from the material manufacturer based on the construction schedule. And we will work in accordance with the detailed construction schedule. Construction companies inspect and inspect buildings as construction progresses. In such a system, various techniques have been introduced in order to automate and improve efficiency in order management and construction management of materials based on design data (see Patent Document 1).
JP 2001-306632 A

The known prior art as described above has the following problems to be solved.
In general, not much construction material can be stored at a construction site. Therefore, the construction shop orders the material and designates the delivery date so that the necessary construction materials are delivered at a predetermined timing according to the construction schedule. However, for that purpose, complicated management such as ordering procedures for various material manufacturers, management of notification of change of designated delivery date associated with change of construction schedule, etc., and receipt of materials are required. On the other hand, even if materials manufacturers receive orders for materials from many construction sites, they will deliver necessary materials individually according to the progress of each construction, which increases transportation costs and affects building prices. There was a problem. If the design and standards of the building are unified, it is possible to batch-produce materials and transport them in bulk according to the construction schedule. However, if each building is constructed with its own design, it is difficult to standardize construction materials. In addition, since the construction progresses with free construction schedules, it is difficult to transport the materials to each site at the same time.
The present invention solves the above-described problems, and enables a construction material delivery management system, a construction management method, and a recording program for recording the construction material, which enable the efficiency and cost reduction of the construction material delivery work to the construction site.

  Data including material names and quantities can be generated from design document data or the like. The order lead time can be calculated based on the material delivery results. When the construction manager inputs a desired delivery date to the site in accordance with the planned construction schedule, the order date is automatically calculated and a purchase order is generated. In this way, the order management of materials can be supported.

<Configuration 5>
In the construction material delivery management system according to any one of Configurations 1 to 3, the material delivery management means is configured so that the number of material delivery to the construction site is within a certain number according to the type of main construction.

  By limiting the number of times the material is carried in so as to be within a certain number of times according to the type of main construction, construction using the carried material efficiently becomes possible. In addition, the progress of the construction can be easily estimated from the material loading status. By adjusting the material delivery date so that it automatically goes back a certain number of days from the delivery date, the material can be delivered to the construction site in a minimum number of times, such as once for each major construction, or twice. Material order data can be automatically generated when a material delivery date is entered.

  In the present invention, the relay collection station is arranged at a location that is geographically convenient for carrying construction materials to a plurality of construction sites. Delivery of materials to the relay depot is the responsibility of the material manufacturer. A large number of materials made by the same material manufacturer used in a plurality of buildings are collectively loaded on, for example, one vehicle and transported to a relay collection station. The computer at the relay collection station transmits the material order data to the material manufacturer at a predetermined timing so that the material delivery process of the material manufacturer can be efficiently performed. Material manufacturers can reduce the transportation cost of materials because they can load materials from multiple buildings and deliver them to a specific place at the same time.

  The computer at the relay depot executes the processing for receiving the ordered material. Furthermore, a process for generating material carry-in management data and carry-in instruction data to all construction sites under its jurisdiction is executed. Moreover, the construction progress recording process of each construction site is executed. There is usually no space to stack a lot of materials on the construction site. In addition, if the timing of arrival of materials at the construction site is not appropriate, smooth construction is hindered. Therefore, the computer at the relay depot will make a plan so that the necessary materials can be delivered to the construction site without omission at the optimal timing, and output management data for material ordering, management, and material delivery management operations. To do.

  The material delivery plan data and the material delivery plan change data to the building construction site are created individually for each building. By setting conditions such as the number of times of loading, an efficient loading plan can be automatically generated. Then, based on these plans, for example, materials delivered by a plurality of material manufacturers can be collectively loaded onto one vehicle and carried into each construction site at a designated timing. Since the operation of the vehicle can be outsourced to a person who is familiar with the geography of the construction site, materials can be carried in efficiently. In accordance with the construction process, necessary materials can be loaded and loaded on one vehicle at a time, reducing traffic noise, acceptance checking, and carrying costs. In addition, since the timing of carrying materials to the construction site can be optimized, the construction can be carried out smoothly. Hereinafter, embodiments of the present invention will be described in detail for each example.

[System overall configuration]
FIG. 1 is a conceptual diagram illustrating a construction material delivery management system according to the first embodiment.
This system is realized centering on the relay collection terminal 18. As shown in the figure, the material ordering / ordering system 12, the construction shop terminal 14, the material manufacturer terminal 16, the relay collection terminal 18, and the construction site terminal 20 are connected through a computer network. The material ordering / ordering system 12 is provided in a construction company. The construction shop terminal 14 is provided in a construction shop commissioned to construct a building. The number of construction shops is arbitrary. The material maker terminal 16 is in a material maker that supplies materials, and there may be an arbitrary number in any place in Japan. The relay depot station 18 is provided at the relay depot 5 installed at a certain distance or less from the construction site under management. The construction site terminal 20 is a mobile phone or the like possessed by a person in charge of construction at the construction site. For example, about one relay depot is provided in each prefecture or city. And, for example, dozens of jurisdiction over construction sites under construction. Some construction shops are entrusted with the construction of two or more buildings at the same time, but since the construction schedule and design are different, each construction site is managed independently. That is, materials are carried in according to their own schedules.

FIG. 2 is a specific functional block diagram of the relay collection terminal 18.
First, the configuration of the relay collection terminal 18 that plays the central role of the system will be described. As shown in the figure, the relay collection terminal 18 is connected to the material ordering system 12, the construction shop terminal 14, the material manufacturer terminal 16, and the construction site terminal 20 through a network. The relay collection station terminal 18 is provided with a storage device 22 and an arithmetic processing device 50. The storage device 22 stores material ordering data 24, delivery result data 26, material delivery management data 34, and the like for material delivery management to a material manufacturer. In addition, for carrying in materials to the construction site, material carry-in plan data 28, material carry-in plan change data 30, material carry-in record data 32, material carry-in instruction data 36, and material carry-in completion report 38 are stored. In addition, the storage device 22 stores construction progress status data 40 and transfer registration information 42. The arithmetic processing device 50 includes material delivery management means 52, material carry-in management means 54, and progress management means 56. These means are constituted by a computer program that gives a predetermined function to the computer of the relay collection terminal 18.

  Each construction site building is uniquely designed and constructed independently. The material ordering data 24 is created by using the building design data included in the management data 13 in the material ordering system 12. Used for printing purchase orders. The delivery record data 26 is data indicating the delivery record of the material from the material manufacturer to the relay collection station. The material carry-in plan data 28 is data indicating a material carry-in plan from the relay collection site to the construction site. The material carry-in plan change data 30 is data indicating a change in the material carry-in plan. It is generated only at the time of change, and then incorporated into the material carry-in plan data 28. The material carry-in record data 32 is data in which the actual material carry-in record from the relay collection point to each construction site is recorded. Compared with the material carry-in plan data 28, undelivered materials can be confirmed.

  The material delivery management means 52 has a function of comparing the material ordering data 24 and the delivery result data 26 for each building and generating material delivery management data 34 including an indication of the presence or absence of insufficient materials. The material delivery management data 34 also includes contact data for notifying the material maker of missing items or for exchanging defective items. Thereby, it can be determined whether or not all materials can be brought into the construction site in a batch as planned on the material carry-in date. In the case of a shortage, material carry-in plan change data 30 is generated and transmitted to the construction shop terminal 14 and the construction site terminal 20. Furthermore, the material carry-in plan data 28 is corrected. The material carry-in management means 54 has a function of correcting the material carry-in plan data 28 for each building based on the material carry-in plan change data 30 and generating at least the latest material carry-in instruction data 36. This carry-in instruction is printed and delivered to a person in charge of the transportation company that carries the material carrying-in work. When the material is safely delivered, the material delivery completion report 38 is accepted and the material delivery result data 32 is updated. The progress management unit 56 has a function of determining a completed process and a process that has not been completed based on the material carry-in result data 32 and generating construction progress status data 40.

  When materials are ordered using the system as described above, and materials are delivered collectively from a material manufacturer to a relay depot, the materials of a plurality of buildings are delivered together to the depot. Then, based on the material carry-in plan data 28 to the building construction site, a plurality of necessary materials are collected and carried to the construction site at an optimal timing. By separating the means of transportation at the relay collection point, the most efficient transportation system can be constructed for both the delivery of materials from the material manufacturer and the delivery to the construction site. As a result, the transportation cost and the carry-in management labor of materials are sufficiently reduced.

  The material ordering / ordering system 12, the construction shop terminal 14, the material manufacturer terminal 16, the relay collection terminal 18, and the construction site terminal 20 can all be configured by adding a network connection function to a known personal computer. . In other words, the following processing can be executed as long as the processing device, the storage device, and the network interface are provided. Data necessary for arithmetic processing by each computer can be stored using not only a built-in storage device but also an external storage device or a storage device of another computer on a network. In addition, a terminal that is used exclusively for sending and receiving forms such as purchase orders and instructions can be replaced with a facsimile machine.

[Ordering materials]
As shown in FIG. 1, the computer that manages the material ordering system 12 stores management data 13 that is created when an order for a building is received from a client. The management data 13 includes building design drawing data and a material manufacturer list. The computer that manages the material ordering / ordering system 12 automatically generates the material ordering data 24 and transmits it to the construction shop terminal 14. That is, the construction shop terminal 14 stores design drawing data 23 and material ordering data 24 transferred from the material ordering / ordering system 12. The construction company and the construction shop will discuss the specifications of the building and the construction schedule. Based on the construction schedule, specify the various materials required for construction and the delivery date and place an order with the material manufacturer. The material delivery date is determined according to the material delivery plan to the construction site. Material order management is performed by the material ordering system 12 or the relay collection terminal 18. In the following embodiment, an example is shown in which the relay depot station 18 performs. As shown in FIG. 1, the material ordering data 24 with the delivery date added is transferred to the relay collection terminal 18. Then, the material order data 24 is transmitted from the relay collection terminal 18 to the material manufacturer terminal 16.

FIG. 3 is an explanatory diagram of the contents of the material order related data.
The relay collection terminal 18 creates material ordering data 24 as shown in the figure and transmits it to the material manufacturer terminal 16. The material order data 24 includes a purchase order 60 for each material manufacturer. The purchase order 60 for each material manufacturer includes data such as a material name 62, an order quantity 63, a material delivery destination 64, a delivery date 65, etc. in a template 61 of the purchase order. The material delivery destination is a relay depot. The designated delivery date indicates the delivery date to the relay collection station. Based on the material order data 24, the delivery record data 26, the material delivery management data 34, and the transfer registration information 42 are sequentially updated. As shown in the figure, the delivery result data 26 includes the name of the material manufacturer, the name of the ordered material, the order date and the delivery date. As shown in the figure, the material delivery management data 34 includes the name of the material manufacturer, the name of the ordered material, the missing item report, the defect report, and the like. The transfer registration information 42 includes the transfer date when the management responsibility is transferred from the material manufacturer to the construction shop as shown in the figure. This transfer date is the date of delivery of the material. As will be described later, the material ordering data 24 is generated with reference to the material carry-in plan data 32. The material carry-in plan data 32 includes the construction site, the carry-in material, the carry-in date, etc., as shown in the figure. Note that the entire material ordering data 24 as shown in the figure may be created on the material ordering system 12 side and transmitted to the material manufacturer terminal 16.

[Change management responsibility]
In the past, material manufacturers were responsible for bringing materials to the construction site. Therefore, it was requested to carry in at the designated date and time. Because it cannot be advanced, it may not be possible to mix with other materials. In addition, when transported from a remote location, drivers who are not guided by the geography need road guidance by telephone or the like, which puts a burden on the driver and on the receiving side. Furthermore, if there is no person in charge of receiving at the construction site, waiting time or take-away occurs. This led to an increase in transportation costs. This problem can be solved by accepting all materials at the relay collection point and controlling the timing of ordering to enable mixed loading and advance delivery.

  Here, even after receiving the material at the relay collection point, if the material is carried into the construction site on the responsibility of the material manufacturer, it is no different from the system of the conventional distribution / collection center. In this system, after receiving materials at the relay collection point, the responsibility for managing the materials is automatically transferred to the construction company or the construction shop side. That is, when the material delivery record data 26 of each building is updated by the delivery data input of a new material, the material delivery management means 52 stores transfer registration information to the construction side responsible for managing the material in the delivery record data 26. 42 is included. As a result, the end point of the material management responsibility of the material maker can be automatically recorded, and this system can be properly operated.

[Delivery of materials]

FIG. 4 is an explanatory diagram showing the relationship between the material and the delivery date of the material designated by the material manufacturer.
Material manufacturers receive orders for materials for multiple construction sites under the jurisdiction of a single relay depot. Assume that this material manufacturer produces six types of materials A-F. In the delivery of materials from the material manufacturer to the relay collection point, the materials to be shipped together with the date of shipment are selected so that the number of transportation (cost) of materials is minimized. The delivery date is displayed in the material order data 24. The material manufacturer terminal 16 creates a list of materials that can be delivered to the relay collection point among the materials displayed in the material ordering data 24 received at the present time. The material of the delivery date within the dashed-dotted line frame is included in the list. In this way, a plan for loading and transporting on one vehicle in order from the material of the latest delivery date is generated.

  For example, if today's day is 1 and the delivery date specified on the 3rd, 4th, and 5th is loaded with the materials A-F, it will be exactly one truck. It is good to decide the shipment amount so that it will arrive. Ship one by one, starting from the one with the closest delivery date. The delivery dates from the 3rd to the 7th may be bundled. This is because, unlike the construction site, the relay depot has a sufficient storage space for materials. By executing such calculation processing at the material manufacturer terminal, the material can be delivered to the relay collection station at the minimum cost. In addition, since the material manufacturer only has to take responsibility for delivering the material to the relay collection point, the cost calculation can be simplified. In addition, in order to deliver a material with a delivery date specified on the 5th to the 3rd, production will be advanced. They also need to have a significant amount of inventory. Expecting this on the ordering side does not lead to a reduction in selling price costs. Therefore, materials are ordered at the following timing.

FIG. 5 is an explanatory diagram of the transmission timing of the material ordering data.
In order to enable the above processing without difficulty, the material ordering data 24 is transmitted from the relay collection terminal 18 to the material manufacturer at a predetermined timing. The delivery date determined as follows is included in the material ordering data 24 to be transmitted. First, the material delivery date D1 to the construction site designated by the material delivery plan data 28 is referred to. Then, a date that is a predetermined number of preliminary days X from the carry-in date D1 is designated as the delivery date D2. The spare days X are set to the number of days that does not affect the delivery date even if the delivery of materials is delayed by several days. Further, a date that is retroactive from the delivery date D2 by adding the standard delivery date Y and the adjustment date Z is set as the transmission date (order date D3) of the material order data.

The standard delivery date Y is determined by the type of material and the circumstances specific to the material manufacturer. This is determined with reference to the material delivery result data 26 . For example, the average value of the latest actual delivery date, that is, the average value of the number of days from the order date to the delivery date of the same material may be obtained. Furthermore, it is preferable to add the adjustment days Z to the standard delivery date Y so that the material maker can easily perform batch delivery for a plurality of material ordering data. This eliminates the need to force production or increase inventory. If these calculation processes are automatically executed and the material ordering data is transmitted, the material manufacturer can automatically optimize the transportation cost. The spare days X may be a constant.

The number of days obtained by adding the standard delivery date Y obtained from the material delivery record data 26 and the adjustment days Z will be referred to as order lead time. The order lead time can be obtained by performing calculation processing with reference to the delivery record data 26 of the material manufacturer. The material delivery management means 52 (FIG. 1) generates the ordering data of the material, including the material name, quantity and delivery date, when the on-site delivery date of the building material is designated. Control is performed to transmit the material ordering data to the material manufacturer terminal 16 before the date traced by the lead time. The purchase order may be sent by e-mail or fax. Now you can place an order automatically at the optimal timing. It is up to the ordering side to add the spare days X and other margins to the ordering lead time. This should be determined in consideration of the material storage capacity of the relay depot. In this way, the order management of materials can be supported.

[Importing materials]
FIG. 6 is an explanatory diagram of a material carry-in plan.
The relay collection terminal 18 manages a material carry-in plan from the relay collection station to the construction site. In this system, the number of times the material is brought into the construction site is limited on the computer in advance so as to be within a certain number of times determined according to the type of main construction. In this embodiment, it is limited to a maximum of 9 times. In the example in the figure, once during the body construction, once during external woodwork and roof construction, twice during floor construction, once during opening frame construction, twice each during wall / ceiling construction and wood finishing construction It is set. Considering the site conditions, construction time, and building specifications, select the materials to be carried in each time and decide the date of delivery. When this carry-in date is input, a reverse calculation is automatically performed to determine a delivery date when the material is delivered from the material manufacturer to the relay collection station. If the number of carry-in dates exceeds the limit, input may be rejected. This delivery date is included in the material order data. The relay collection terminal 18 creates the material carry-in plan data 28 and transmits it to the construction shop terminal 14, the construction site terminal 20, and the like.

  For example, in the example of FIG. 6, the first site delivery date is December 20th. Accordingly, the date when the corresponding material is delivered from the material manufacturer to the relay collection station is automatically set to December 17. When the material carry-in plan is changed due to circumstances at the construction site, the material carry-in plan change data 30 is created and processed. Even if the material is brought in but not accepted at the construction site, or if the material is defective and returned, it can be processed by managing the relay depot 18 so that it does not significantly affect the transportation cost and management cost. . In other words, it is possible to respond freely and finely.

  Ideally, materials should be brought from the relay collection site to the construction site in accordance with the circumstances specific to the construction site. In the past, materials were sent directly from material manufacturers, so the material delivery plan to the site also considered the circumstances of the material manufacturers. However, in the system of the present invention, necessary materials are accumulated at the relay depot, and all can be managed at the relay depot, so it is only necessary to carry in materials at an optimal timing according to the progress of the construction. For this, for example, it is most preferable that materials necessary for the day are carried in on the previous day. However, too fine delivery increases transportation costs and makes reception management complicated. Therefore, the optimum number of on-site delivery was set in line with the standard main construction as described above.

  For example, the number of times is set to 9 and is set to the maximum value. That is, for example, if a carrying-in plan is made based on an approximation that one wooden house can be constructed with materials for nine trucks, the carrying-in cost can be optimized. After that, fine adjustments may be made according to circumstances such as construction progress and delays in delivery of materials. For example, at the time of floor construction in FIG. 6, there was a shortage of the underfloor inspection port at the third and fourth on-site delivery. On the other hand, the pit used in the wood finishing work was delivered early, so it was transported at the third import. In this way, necessary materials can be transported within a limited delivery date range.

FIG. 7 is an explanatory diagram showing the relationship between the progress of the construction and the material delivery results.
The storage device 22 shown in FIG. 2 stores construction progress status data 40 indicating the relationship between the imported material, the date of delivery, and the completed construction, as shown. The progress management means 56 has a function of generating construction progress status data 40 by referring to the material carry-in result data 32 shown in FIG. The construction progress status data 40 is checked by the manager of the construction shop or the management department of the construction company. When a new construction material is carried into the construction site, the process using the material carried in last time is almost completed. Therefore, when the material carry-in record data 32 is updated, it is possible to manage the progress of the construction, assuming that the process using the material delivered last time has been completed. Thereby, even if there is no sequential report of the construction progress from the contractor, the construction progress can be predicted and managed almost accurately. In general, reports of construction progress are often delayed or forgotten. Therefore, it is extremely effective in terms of management to be able to automatically monitor the progress of construction with this system.

FIG. 8 is a processing operation flowchart of the material ordering system.
This process is executed by the material ordering system 12 of the construction company. First, in step S11, the management data in the material ordering system 12 is read. In step S12, the material order data 24 is automatically generated. This material ordering data 24 is transferred to the relay collection terminal 18. Depending on the case, the data is transferred to the construction shop terminal 14 or the material manufacturer terminal 16. When the relay collection terminal 18 performs all order management, the material order data 24 may be directly transferred from the material ordering system 12 to the relay collection terminal 18. In addition, the material ordering / order receiving system 12 may receive material ordering data 24 from the construction shop terminal 14 to the construction site and transfer the material ordering data 24 to the material maker terminal 16. Since management after ordering is performed at the relay collection station terminal 18, the relay collection station terminal 18 always receives the transfer of the material order data 24.

FIG. 9 is a flowchart of the processing operation of the relay depot station.
Here, an example will be described in which the relay collection terminal 18 adds data such as a delivery date to the material ordering data 24 and transmits it to the material manufacturer terminal 16. In step S21, material ordering data is received from the material ordering system 12. In step S22, information on the construction shop terminal 14 and the like is acquired, and material carry-in plan data 28 is generated. In step S23, the number of spare days described in FIG. 5 is acquired. This may be arbitrarily determined according to the circumstances of the construction shop or the construction site. In step S24, a delivery date is calculated and determined.

In step S25, the standard delivery date and the number of adjustment days are acquired with reference to the material carry-in result data 26 and the like. In step S26, the order date is calculated and determined in the manner described in FIG. In step S27, the result of step S23 and the result of step S26 are added to the material order data 24 and updated. Thus, the material ordering data 24 can be transmitted to the material manufacturer terminal 16 at any time.

FIG. 10 is a flowchart of the order management operation of the relay depot station.
In this embodiment, the order processing is performed from the relay collection point, and the subsequent delivery management is advanced. The following processing is mainly executed by the material delivery management means 52. In step S31, it is determined whether or not the order date has been reached with reference to calendar data or the like. If the result of this determination is yes, the process proceeds to step S32. If the result is no, the process ends. In step S 32, the material ordering data material ordering data 24 is transmitted to the material manufacturer terminal 16. In step S33, it is determined whether or not material delivery data has been input. If the result of this determination is yes, the process proceeds to step S34, and if no, the process proceeds to step S38. In step S34, transfer registration information is generated for each delivered material, and the ownership is transferred to, for example, a corresponding construction shop. The subject of management responsibility may be substantially switched, and the data format is arbitrary.

  In step S35, the delivery record data described in FIG. 3 is generated. In step S36, it is determined whether or not a delivery date delay has occurred. When the result of this determination is yes, the process proceeds to step S37, and when no, the process proceeds to step S38. In step S37, material delivery plan change data is generated to change the delivery date for materials that have been delayed in delivery. In addition, if it is in the range of the reserve day demonstrated in FIG. 5, there will be no change in a delivery date. Accordingly, the determination in step S37 may be controlled such that if the delivery delay occurs more than the preliminary date, the process proceeds to step S38. In step S38, the material delivery management data 34 described with reference to FIG. 3 is generated. Such management is executed for all materials.

FIG. 11 is a flowchart of the carry-in management operation of the relay collection terminal.
In step S41, material carry-in plan data is generated. This is the same as the process in step S22 of FIG. I wrote it at the top of this flowchart just in case. In step S42, the material carry-in management means 54 determines whether or not the material carry-in plan change data is input. The input of the material carry-in plan change data is executed at any time from the construction shop terminal 14 or the construction site terminal 20. When the result of this determination is yes, the process proceeds to step S43, and when no, the process proceeds to step S44. In step S43, the material carry-in plan data is updated. In step S44, it is determined whether or not the carry-in date has been reached with reference to calendar data or the like. If the result of this determination is yes, the process proceeds to step S45, and if no, the process ends.

  In step S45, material carry-in instruction data is generated. In step S46, the material carry-in instruction data is transmitted to the material transporter. This data may be printed and passed to the carrier. After that, we wait for the material delivery report. In step S47, it is determined whether a material carry-in completion report has been input. If the result of this determination is yes, the process proceeds to step S48, and if no, the process waits as it is. In step S48, the delivery of the corresponding material is confirmed, and the material delivery result data is generated. In step S49, construction progress status data is generated in the manner described in FIG. This data is transferred to the material ordering system 12 or the like as necessary. This process is executed by the progress management means 56.

  According to the above system, the material manufacturer can collectively deliver materials for a plurality of construction sites to the relay collection point, so that it is possible to reduce transportation costs and material delivery management costs. In addition, since necessary materials can be carried in from the relay collection site to the construction site at a specified timing, the transportation cost can be reduced and the number of receiving operations can be reduced. For example, when materials are individually delivered from a material manufacturer, a number of vehicles arrive at the site for delivery on the same day. This increases the traffic volume at the site and makes the reception work complicated. For example, if there is no person in charge at the construction site, transportation costs will be increased due to repatriation. On the other hand, among the materials delivered to the relay collection station, if the materials necessary for the day are brought into the corresponding construction site in a lump, the number of times of carrying in can be minimized and the number of receiving operations can be minimized.

  Each time a material is transported from a distant material manufacturer, the person in charge of the transport will inquire about the location of the construction site. The work corresponding to this also becomes complicated. These inquiries are drastically reduced when transporters who know the area from a relay depot bring in materials. Furthermore, according to a transport person accustomed to carrying materials from the relay collection point, damage accidents during transportation of materials are reduced. Since the ownership of the material can be transferred from the material maker to the contractor by delivering the material to the relay collection point, the scope of responsibility can be clarified and the management cost can be reduced on both sides.

  In addition, the material delivery timing can be freely and finely adjusted according to the progress of the construction, contributing to smooth construction work. Since the relay depot can notify the construction site of material delivery time and the like relatively accurately, the work efficiency at the site is also improved. Since material delivery management from material manufacturers and material delivery management to construction sites can be unified, management optimization is easy. In fact, by implementing this method, it was possible to simultaneously reduce the number of times of transportation from the material manufacturer and the number of times of material transportation to the construction site. Compared to the case where the material manufacturer directly brought the material to the construction site, it was found that the carbon dioxide emission could be reduced by 35% and the effect of preventing global warming was great.
