  Further, the transport vehicle management number information is different data for each concrete mixer truck in order to identify the concrete mixer truck that transports the concrete from the raw plant to the construction site in the corresponding construction work (in this embodiment, numerical value). Data).

  The acceptance inspection information is information indicating the quality of the inspection result regarding the quality at the time of acceptance of the concrete transported by the corresponding concrete mixer truck, and the finish inspection information is the corresponding concrete mixer truck. It is the information which shows the quality of the test result regarding the finishing state of the concrete conveyed by. As shown in the figure, in this embodiment, the acceptance inspection information and the finished inspection information are used as information indicating a good state, character information “OK” is used as information indicating a good state, and information indicating a bad state is used. Although character information of NG ′ is applied to each, it goes without saying that numerical information corresponding to each state can be applied instead of the character information.

  On the other hand, as shown in FIG. 4C, the elapsed time management information database DB3 according to the present embodiment includes construction management number information, placement location information, transport vehicle management number information, transport start time information, and site arrival time. Each information of information, placement start time information, and placement end time information is stored.

  The construction management number information, the placement location information, and the transport vehicle management number information are the same as the construction management number information, the placement location information, and the transport vehicle management number information in the above-described quality management information database DB2, respectively. It is.

  Further, the transport start time information is information indicating a time when the corresponding concrete mixer truck starts transporting from the concrete concrete plant, and the on-site arrival time information is the corresponding concrete mixer truck arrived at the construction site. It is information indicating the time, the placing start time information is information indicating the time when placing by the concrete transported by the corresponding concrete mixer truck is started, and the placing end time information further corresponds. It is the information which shows the time when placement by the concrete conveyed by the concrete mixer truck was completed.

  On the other hand, as shown in FIG. 4D, each information of construction management number information, placement location information, and placement start time information is stored in the overlapping placement interval management information database DB4 according to the present embodiment. It is configured as follows.

  The construction management number information and placement location information are the same as the construction management number information and placement location information in the above-described quality management information database DB2.

  The placement start time information is information indicating the concrete placement start time for each section when the corresponding placement place is divided into a plurality of sections in a plan view.

  When placing concrete, usually, one place to be placed is viewed in plan and divided into a plurality of sections in a mesh shape, and the concrete is overlaid in multiple sections for each section. This is due to various problems such as the need to make the formwork stronger as the height of the poured concrete increases, and the possibility that the concrete will be separated as the distance to which the concrete is dropped increases. This is done to avoid the point.

  Therefore, as shown in the figure, the overstrike interval management information database DB4 according to the present embodiment has a plurality of (two in the present embodiment) strikes for each section as the placement start time information. The configuration start time is stored. In addition, in the overlap-pitch-interval management information database DB4, the transport vehicle management number information of the mixer truck that transports the concrete that has been placed in the corresponding placement time for the corresponding section in association with the placement start time information ( The information shown in parentheses in the placement start time column in the figure is stored.

  In addition to the above database, the database area DB of the hard disk 20D indicates required quality information indicating the quality required for the concrete to be placed in the building under construction and the amount of concrete required.

Various databases, such as the stored charge information database (not shown) for each field office are stored.

  Next, with reference to FIG. 5, the effect | action of the concrete construction management assistance system 10 which concerns on this Embodiment is demonstrated. FIG. 5 shows a program for supporting the quality control of concrete at the time of placing the concrete registered on the building registered in the database. The CPU 20A of the server device 20 responds to an instruction input from the user to the server device 20. Is a flowchart showing the flow of processing of the concrete construction management support program executed in the above, and the program is stored in advance in the program area PG of the hard disk 20D. Here, in order to avoid complications, the quality control of concrete is supported for one building (hereinafter referred to as “managed building”) designated in advance by the user among a plurality of registered buildings. The case will be described.

  First, in step 100, all the information stored in the plant information database DB1 is read out, and all the information related to the management target building stored in the requirement condition information database (required quality information, necessary amount information, construction site). Information, partition state information).

  In the next step 102, based on the information read in the step 100, a concrete hitting design image for the management target building is drawn up.

  In addition, here, the concrete having the quality indicated by the read required quality information can be supplied in the amount indicated by the read necessary amount information, and the place closest to the construction site indicated by the read construction site information. The raw plant located in is selected as the concrete supplier.

  Here, the concrete placement order for each section is determined based on the section state at each placement location indicated by the read section state information.

  In the next step 104, ordering instruction information indicating a concrete ordering instruction is output via the network 12 to the client device 30 installed in the raw plant selected in the striking design image planned in the above step 102. . The ordering instruction information includes required quality information, necessary amount information and construction site information read in step 100, placement order information indicating the concrete placement order determined in step 102, and placement date and time. And the placement date and time information indicating.

  In the raw plant where the client device 30 that has input the ordering instruction information as described above is installed, the concrete of the quality indicated by the ordering instruction information at a time corresponding to the placement date and time indicated by the ordering instruction information, After the concrete is manufactured so that the required amount indicated by the ordering instruction information can be transported to the construction site (construction site) indicated by the ordering instruction information and loaded on a plurality of concrete mixer trucks, the construction site Start transporting to

  At this time, each concrete mixer truck stores transport vehicle management number information for identifying itself, transport start time information indicating the transport start time, and quality information indicating the quality of the loaded concrete. A possible non-volatile storage device (in this embodiment, an IC tag) is installed at a predetermined position (in this embodiment, the door surface of the driver's seat) of the concrete mixer truck.

  And in the said raw concrete plant, whenever the conveyance by each concrete mixer truck is started, the conveyance start information including the conveyance vehicle management number information for specifying the said concrete mixer truck is sent to the server device 20 as a client. The data is output via the device 30 and the network 12.

  Therefore, in the next step 106, it is determined whether or not the conveyance start information has been input from any of the client devices 30. If the determination is affirmative, the process proceeds to step 108.

  In step 108, the transport vehicle management number information included in the input transport start information and the time at this point correspond to the construction management number information indicating the management target building in the elapsed time management information database DB3, and It is stored as transport vehicle management number information corresponding to the placement location information indicating the planned placement location of the concrete transported by the concrete mixer truck indicated by the transport vehicle management number information, and transport start time information. In Step 108, the transport vehicle management number information included in the input transport start information corresponds to the construction management number information indicating the management target building in the quality management information database DB2, and is indicated by the transport vehicle management number information. It is stored as transport vehicle management number information corresponding to the placement location information indicating the planned placement location of the concrete transported by the concrete mixer truck.

  In the next step 110, a placement allowable time indicating a permissible period until the concrete placement end is started from the conveyance start time stored in the step 108, and stored in a predetermined area of the hard disk 20D in the step 108. The transported vehicle management number information is stored in association with it, and then the process proceeds to step 112.

  That is, the upper limit period (hereinafter referred to as “the pouring end upper limit period”) from the end of mixing of the concrete to the end of pouring when the concrete is placed is predetermined as a standard specification. Specifically, the casting end upper limit period when the temperature is 25 ° C. or higher is 90 minutes, and the casting end upper limit period when the temperature is less than 25 ° C. is 120 minutes. Note that, in the concrete construction management support system 10 according to the present embodiment, the concrete conveyance start time is used instead as the substantially equal time when the concrete mixing ends.

  On the other hand, the period required for placing concrete is highly accurate based on the order of placing concrete determined in step 102, the necessary amount information read out in step 100, past concrete placement information, and the like. Can be predicted.

  From the above, in the concrete construction management support system 10 according to the present embodiment, the time when the estimated time required for placing is traced from the time when the casting finish upper limit period has elapsed from the transfer start time is the above-described placement permission. Calculated as time. In other words, the placement allowable time calculated here represents the time when the placement is started after the time is exceeded and the period until the placement is completed cannot satisfy the predetermined standard specifications. ing.

  As described above, the placement end upper limit period is defined by the air temperature, and therefore the air temperature at the construction site is appropriately input to the server device 20 according to the present embodiment.

  On the other hand, if a negative determination is made in step 106, the process proceeds to step 112 without executing the processing of step 108 and step 110.

  In step 112, it is determined whether any of the permissible placement times stored in the hard disk 20D by the processing in step 110 has elapsed so far. If the determination is affirmative, the process proceeds to step 114.

  In step 114, the client device 40 installed in the site office provided at the construction site of the building to be managed may not be able to satisfy the predetermined standard specifications for the period until the placement is completed. Notification information for notifying that high concrete is present is output, and then the process proceeds to step 116.

  In the present embodiment, the notification information is specified by the transport vehicle management number information stored in the hard disk 20D in association with the placement allowable time that has been the object of affirmative determination in step 112. The concrete that is transported by the concrete mixer truck is highly likely not to satisfy the standard specifications, and screen information that can display the transport start time of the concrete mixer truck on the display is output. In addition, the said conveyance start time can be obtained by reading the conveyance start time information corresponding to the said concrete mixer truck from elapsed time management information database DB3. As a result, a screen as shown in FIG. 12 is displayed on the display of the client device 40 as an example. When such a screen is displayed, one of the members of the site office takes action according to the notification content such as instructing the concrete mixer truck in question to shorten the transport time. Do.

  If the determination in step 112 is negative, the process proceeds to step 116 without performing the process in step 114.

  By the way, at the construction site of the building to be managed, the IC tag reader 42 (see FIG. 4) is located at a position where the stored contents of the IC tag installed in the concrete mixer truck can be read when the concrete mixer truck passes. 1 is also provided, and the IC tag reader 42 is connected to a client device 40 installed at a site office provided at the construction site.

  Therefore, the client device 40 can detect the passage of the gate of the concrete mixer truck and can read out the stored contents of the IC tag installed in the passing concrete mixer truck.

  Then, when the information stored in the IC tag provided in any of the concrete mixer trucks (the transport vehicle management number information, the transport start time information, the quality information) is read out, the client device 40 Arrival information indicating that the concrete mixer truck has arrived is output to the server device 20. In the concrete construction management support system 10 according to the present embodiment, the vehicle management number information read from the IC tag is included in the arrival information.

  Accordingly, in step 116, it is determined whether or not the arrival information has been input from any of the client devices 40. If the determination is affirmative, the process proceeds to step 118. If the determination is negative, the process proceeds to step 122 described later. Transition.

  In step 118, the time at this point is stored in the elapsed time management information database DB3 as on-site arrival time information corresponding to the transport vehicle management number information included in the input arrival information. In the next step 120, the arrival time determination The processing routine program is executed. Here, the arrival time determination processing routine program will be described with reference to FIG. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 200, it is determined whether or not the arrival time of the concrete mixer truck that has arrived at the construction site satisfies a predetermined standard specification.

  That is, the upper limit period (hereinafter referred to as “arrival upper limit period”) from when the concrete is mixed to the arrival at the construction site when the concrete is placed is predetermined as a standard specification. Specifically, the arrival upper limit period when the temperature is 25 ° C. or higher is 90 minutes, and the arrival upper limit period when the temperature is less than 25 ° C. is 120 minutes. In the concrete construction management support system 10 according to the present embodiment, as described above, the concrete transfer start time is used instead of the substantially equal time at the end of the concrete mixing.

  Therefore, in the above step 200, the conveyance period indicated by the difference between the arrival time of the concrete mixer truck that has arrived at the construction site and the conveyance start time stored in the elapsed time management information database DB3 corresponding to the concrete mixer truck. However, by determining whether or not the upper limit of arrival period corresponding to the temperature at this time has been exceeded, it was determined whether or not the predetermined standard specification could not be satisfied, and an affirmative determination was made. If so, go to Step 202.

  In step 202, access information corresponding to the person in charge of managing the arrival time of the concrete mixer truck is read from the person-in-charge information database. In the next step 204, the arrival information is received with respect to the PDA 60 possessed by the person in charge. The notification information for notifying that the arrival time of the concrete mixer truck that has been satisfied could not satisfy the predetermined standard specification is output, and then the process proceeds to step 206. As a result, a screen as shown in FIG. 13 is displayed on the display of the PDA 60 as an example. Note that the “elapsed time” in the figure is the same as the transport period. When such a screen is displayed, the owner of the PDA 60, after taking measures such as stopping the use of the concrete transported by the arrived concrete mixer truck, The data is output to the server device 20 via the PDA 60 and the network 12 that the user possesses.

  Therefore, in step 206, input of the arrival time handling information is awaited. In the next step 208, the input arrival time handling information is stored in a predetermined area of the hard disk 20D, and then this arrival time determination processing routine program is terminated. Then, the process proceeds to step 122 of the concrete construction management support program.

  In addition, when it becomes negative determination in the said step 200, without performing the process of the said step 202-step 208, this arrival time determination processing routine program is complete | finished and it transfers to step 122 of a concrete construction management assistance program. .

  By the way, in the concrete construction management support system 10 which concerns on this Embodiment, with respect to the concrete conveyed by the concrete mixer truck by the person in charge who performs the concrete acceptance inspection in a construction site, every concrete mixer truck is set. The PDA 60 that the person in charge possesses the inspection information on the workability, the slump inspection for every predetermined concrete amount, the entrained air amount inspection and the chloride amount inspection by the conventionally known technology, and the acceptance inspection result information indicating the result of the inspection Input to the server device 20 via the network 12. In the present embodiment, the acceptance inspection result information includes transport vehicle management number information indicating a concrete mixer truck that transports the concrete that has been inspected by the information.

  Accordingly, in step 122, it is determined whether or not the acceptance inspection result information has been input from the PDA 60 possessed by any person in charge belonging to the field office to be processed. If the result of the determination is negative, the process proceeds to step 130 described later.

  In step 124, the received acceptance inspection result information is stored in a predetermined area of the hard disk 20D, and information corresponding to whether or not the inspection result indicated by the acceptance inspection result information includes a condition that does not satisfy the predetermined allowable condition is included. Then, it is stored in the quality management information database DB2 as acceptance inspection information corresponding to the transport vehicle management number information included in the acceptance inspection result information, and in the next step 126, an acceptance inspection determination processing routine program is executed. Here, the acceptance inspection determination routine program will be described with reference to FIG. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 300, it is determined whether or not the inspection result indicated by the input acceptance inspection result information includes a result that does not satisfy the predetermined allowable condition. If the determination is affirmative, the process proceeds to step 302.

  In step 302, the access information corresponding to the person in charge who deals with the examination that is determined not to satisfy the predetermined permissible condition in step 300 is read from the person-in-charge information database. The notification information for correcting the inspection target that did not satisfy the predetermined permissible condition is output to the PDA 60 to be performed, and then the process proceeds to step 306. As a result, a screen as shown in FIG. 14 is displayed on the display of the PDA 60 as an example. When such a screen is displayed, the owner of the PDA 60 can deal with the concrete subject to the inspection according to the notified content (for example, using a fluidizing agent for the concrete. ), The acceptance inspection handling information indicating the contents of the handling is output to the server device 20 via the PDA 60 and the network 12 possessed.

  Therefore, in step 306, input of the acceptance inspection handling information is waited. In the next step 308, the input acceptance inspection handling information is stored in a predetermined area of the hard disk 20D, and then the acceptance inspection determination processing routine program is terminated. Then, the process proceeds to step 128 of the concrete construction management support program.

  In addition, when it becomes negative determination in the said step 300, this acceptance inspection determination processing routine program is complete | finished and it transfers to step 128 of a concrete construction management assistance program, without performing the process of the said step 302-step 308. .

  In step 128, placement start instruction information for instructing the start of placement using concrete that has passed the above acceptance inspection is output to the PDA 60 possessed by the concrete placement person. In response to this, the concrete placing person who owns the PDA 60 starts placing work for each section in the placing order determined in the above step 102 for each placing place by the concrete that has passed the acceptance inspection. In addition, every time placement is started for each section, placement start information indicating the start of the placement, section specifying information for identifying the section, and a transport vehicle indicating a concrete mixer truck that transports the concrete to be placed Along with the management number information, it is input to the server device 20 via the PDA 60 and the network 12 possessed.

  Therefore, in the next step 130, it is determined whether or not the placement start information is input from the PDA 60 possessed by any concrete placement person belonging to the site office to be processed. Shifts to step 132, and if a negative determination is made, the flow shifts to step 138 described later.

  In step 132, information indicating the time at this time is stored in the overstrike interval management information database DB4 as placement start time information corresponding to the section specified by the section specifying information input together with the placement start information. Here, when the placement start time information is not stored in the “first time” storage area of the section in the overstrike interval management information database DB4, the “first time” is stored in the “first time” storage area. When the placement start time information is already stored in the storage area, information indicating the time at this time is stored in the “second time” storage area. Further, the transport vehicle management number information input together with the placement start information is stored in the overlapping shot interval management information database DB4 in association with the placement start time information. Furthermore, only when the transport vehicle management number information is input for the first time in this step 132, information indicating the time at this time is used as the placement start time information corresponding to the transport vehicle management number information. Store in database DB3.

  In the next step 134, it is determined whether or not the storage area of the overstrike interval management information database DB 4 storing the information indicating the time in the above step 132 is a “second” storage area. Shifting to step 136, the overstrike period determination processing routine program is executed. Here, with reference to FIG. 8, the overstrike period determination processing routine program will be described. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 400, the first placement start time information corresponding to the section in which the second placement start time information is stored by the processing in the preceding step 132 is read from the overstrike interval management information database DB4. In step 402, the difference between the placement start time indicated by the second placement start time information and the placement start time indicated by the first placement start time information is calculated as an elapsed period.

  In the next step 404, it is determined whether or not the calculated elapsed time satisfies a predetermined reference specification.

  In other words, the upper limit of the time interval for overstrike of concrete (hereinafter referred to as “overlap upper limit period”) is set in advance as a standard specification. Specifically, the overstrike upper limit period when the temperature is 25 ° C. or higher is 120 minutes, and the overstrike upper limit period when the temperature is less than 25 ° C. is 150 minutes.

  Therefore, in step 400 and step 402, the actual overlap interval is calculated as an elapsed period, and in this step 404, whether or not the calculated elapsed period falls within the upper limit upper limit period corresponding to the temperature at the construction site. By determining, it is determined whether or not the actual overstrike interval satisfies a predetermined standard specification. If the determination in step 404 is negative, the process proceeds to step 406.

  In step 406, the access information corresponding to the person in charge when the concrete overlap interval does not satisfy the predetermined standard specifications is read out from the person information database, and in step 408, the person in charge is in charge. The notification information for notifying that the reference specification is not satisfied is output to the PDA 60 possessed by, and then the process proceeds to step 410. As a result, a screen as shown in FIG. 15 is displayed on the display of the PDA 60 as an example. When such a screen is displayed, the owner of the PDA 60 can deal with the concrete subject to the determination according to the notified content (for example, the fluidizing agent for the concrete in the section). ), The overstrike information indicating the content of the countermeasure is output to the server device 20 via the PDA 60 and the network 12 possessed.

  Therefore, in step 410, input of the overstrike handling information is awaited, and in the next step 412, the input overstrike handling information is stored in a predetermined area of the hard disk 20D, and then this overstrike period determination processing routine program is executed. Then, the process proceeds to step 138 of the concrete construction management support program.

  In addition, when it becomes affirmation determination in the said step 404, without performing the process of the said step 406-step 412, this overstrike period determination process routine program is complete | finished and it transfers to step 138 of a concrete construction management assistance program. To do. If the determination in step 134 is negative, the process proceeds to step 138 without executing the above-described overstrike period determination processing routine program.

  In step 138, an overstrike period warning process routine program is executed. Here, the overstrike period warning process routine program will be described with reference to FIG. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 500, the first placement start time information for any one section of the sections in which the first placement start time information of the overlapping shot interval management information database DB4 has been stored so far. In the next step 502, the difference between the time at this point and the placement start time indicated by the first placement start time information is calculated as an elapsed period.

  In the next step 504, it is determined whether or not the calculated elapsed period is equal to or shorter than a predetermined allowable period that is a period shorter than the above-described upper limit upper limit period by a predetermined period (10 minutes in the present embodiment), When a negative determination is made, the process proceeds to step 506, where the access information corresponding to the concrete placing person is read out from the person-in-charge information database, and the section to be processed for the PDA 60 possessed by the concrete placing person The notification information for notifying the period (in this case, 10 minutes) until the overstrike interval does not satisfy the standard specification is output, and then the process proceeds to step 508. As a result, a screen as shown in FIG. 16 is displayed on the display of the PDA 60 as an example. When such a screen is displayed, the owner (concrete placement person) of the PDA 60 performs a countermeasure (an example of a countermeasure for increasing the concrete placement speed) according to the notified content.

  If the determination in step 504 is affirmative, the process proceeds to step 508 without performing the process in step 506.

  In Step 508, it is determined whether or not the processing of Step 500 to Step 506 has been completed for all sections where the first placement of concrete has been completed. When the determination is made, the overstrike period warning routine program is terminated and the process proceeds to step 140 of the concrete construction management support program.

  By the way, when the concrete placement person finishes placing concrete for each concrete mixer truck, the placement completion information indicating the completion of the placement is used as a transport vehicle management number for identifying the concrete mixer truck. Along with the information, the information is input to the server device 20 via the PDA 60 and the network 12 that the user has.

  Therefore, in the next step 140, it is determined whether or not the placement completion information is input from the PDA 60 possessed by any concrete placement person belonging to the site office to be processed, and the determination is affirmative. Shifts to step 142, and if a negative determination is made, the flow shifts to step 146 described later.

  In step 142, information indicating the time at this time is stored in the elapsed time management information database DB3 as placement end time information corresponding to the transport vehicle management number information input together with the placement end information, and in the next step 144. Then, a placement end time determination processing routine program is executed. Here, with reference to FIG. 10, the placement end time determination processing routine program will be described. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 600, the conveyance start time information corresponding to the conveyance vehicle management number information in which the placement end time information is stored by the processing in the previous step 142 is read from the elapsed time management information database DB3. In the next step 602, The difference between the transfer start time indicated by the transfer start time information and the time at this time is calculated as the elapsed period.

  In the next step 604, it is determined whether or not the calculated elapsed period satisfies the reference specification (the above-described placement end upper limit period). If the determination is negative, the process proceeds to step 606.

  In step 606, the access information corresponding to the person in charge who takes action when the elapsed time from the person-in-charge information database to the end of placement does not satisfy the standard specification is read, and in the next step 608, the person in charge possesses it. Notification information for notifying that the reference specification is not satisfied is output to the PDA 60 to be performed, and then the process proceeds to step 610. As a result, a screen as shown in FIG. 17 is displayed on the display of the PDA 60 as an example. When such a screen is displayed, the owner of the PDA 60 can deal with the concrete that does not satisfy the standard specifications according to the informed content (for example, a fluidizing agent is applied to the concrete. After performing the countermeasure to be used.), The placement period countermeasure information indicating the countermeasure contents is output to the server device 20 via the PDA 60 and the network 12 possessed.

  Therefore, in step 610, input of the placement period handling information is awaited, and in the next step 612, the inputted placement period handling information is stored in a predetermined area of the hard disk 20D, and then this placement end time determination process is performed. The routine program ends and the process proceeds to step 146 of the concrete construction management support program.

  In addition, when it becomes affirmation determination in the said step 604, without performing the process of the said step 606-step 612, this placement completion time determination processing routine program is complete | finished and it goes to step 146 of a concrete construction management assistance program. Transition.

  By the way, in the concrete construction management support system 10 according to the present embodiment, in the construction site, the defect investigator belonging to the site office, by the defect state of the concrete that has been placed and has not solidified (in this embodiment, The presence / absence of occurrence of a jumper is investigated by a conventionally known technique, and finished inspection result information indicating the result of the investigation is input to the server device 20 via the PDA 60 and the network 12 possessed by the person in charge. In the present embodiment, the finished inspection result information includes transport vehicle management number information indicating the concrete mixer truck that transported the concrete that has been inspected by the information.

  Therefore, in step 146, it is determined whether or not the finished inspection result information has been input from the PDA 60 possessed by any defect investigator belonging to the field office to be processed. If the determination is affirmative, step 148 is performed. If the determination is negative, the process proceeds to step 152 described later.

  In step 148, the input finishing inspection result information is stored in a predetermined area of the hard disk 20D, and information corresponding to whether or not the occurrence of a jumper is indicated by the finishing inspection result information is included in the finishing inspection result information. Stored in the quality management information database DB2 as finish inspection information corresponding to the transport vehicle management number information, and in the next step 150, a finish inspection determination processing routine program is executed. Here, the finished inspection determination processing routine program will be described with reference to FIG. The program is also stored in advance in the program area PG of the hard disk 20D.

  First, in step 700, it is determined whether or not the occurrence of a jumper is indicated by the input finish inspection result information. If the determination is affirmative, the process proceeds to step 702.
