Description

Technical Field

[0001] The present invention belongs to the technical field of engineering control, and in particular relates to a method, medium and equipment for determining the responsibility for delayed construction period based on a double-code network plan. Background Art

[0002] During the construction process, there are many disputes over the construction period when multiple interference events occur at the same time. The existing technical solutions for judging the responsibility for delayed construction period are difficult to satisfy all parties involved. The reason is that the existing technical solutions for judging the responsibility for delayed construction period are often considered from a unilateral perspective, and the judgment is subjective, not unique, and lacks objectivity. The results caused by the responsible parties must be reflected by the jointly acting network status. It is inaccurate to reflect only by the unilateral network status, because the unilateral delay time cannot reflect the situation of mutual conditions in the total time difference. For example, the total time difference of work A in a double-code network is 3 days, and work A is delayed by a total of 4 days, of which the contractor is delayed by 2 days and the contractor is delayed by 2 days. From the analysis of the network plan of the contractor and the contractor alone, neither party caused the total construction period delay. From the analysis of the jointly acting network plan, the total construction period is delayed by 1 day. Obviously, the unilateral analysis result is wrong. 2 days + 2 days = 2 days in 4 days. Only when they are mutually conditional can they add up to 4 days, resulting in a delay of 1 day. Unilateral analysis loses the situation under mutual conditions. This is why unilateral analysis loses the construction period and causes "divergence phenomenon". Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a method, medium and device for determining the responsibility for delayed construction period based on a dual-code network plan.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] In a first aspect, the present invention provides a method for determining the responsibility for delayed construction period based on a dual-code network plan, comprising the following steps:

[0006] Step 1: Draw a double-code network plan diagram of the segmented construction plan, list the expressions of each line and its working duration, and find out the key lines and key tasks;

[0007] Step 2: Subtract the working duration of each non-critical line from the working duration of the critical line, and remove the critical work in the expression of each line to obtain the total time difference calculation formula of the section;

[0008] Step 3: Calculate the total time difference and equity time difference of each work according to the total time difference calculation formula of the road section, where the equity time difference of the work refers to the difference between the duration of the work in the network logic unit and the corresponding key road section time interval. The network logic unit is a network composed of two roads between any two key nodes. The work on one road section is all critical work, and there are non-critical work on the other road section.

[0009] Step 4: Divide the responsibility of each task for the total delay in the construction period based on the actual number of days of delay and the equity time difference of each task.

[0010] Optionally, in step 3, the total time difference of the work is calculated as follows:

[0011] Take the minimum value of the total time difference calculation formula for the section where the work is located as the total time difference of the work.

[0012] Optionally, in step 4, the division of responsibilities of each task for delaying the total construction period is specifically as follows:

[0013] Substitute the actual delay days of each work into the total time difference calculation formula of each road section, determine whether the work in the total time difference calculation formula of each road section delays the total construction period, and obtain the road section associated with the delayed total construction period;

[0014] For the road sections associated with the delayed total construction period, the number of delayed days of each work in the road section is subtracted from its equity time difference, and the responsibility of each work for the delayed total construction period is divided according to the difference.

[0015] Optionally, in step 4, the determination of whether each task in the total time difference calculation formula for each road section delays the total construction period is specifically as follows:

[0016] Substitute the actual number of days of delay t1 of each work into the total time difference calculation formula for each section and compare the value obtained with the total time difference t2 of the total time difference calculation formula for the section. If t1≤t2, it means that the total construction period of the section is normal; if t1>t2, it means that the section is a section associated with the total delayed construction period, and the difference t1-t2 is the total number of days of delay in the construction period of the section.

[0017] Optionally, in step 4, the responsibility of each task for the total delay in the construction period is divided according to the difference, specifically:

[0018] For each work involved in the total time difference calculation formula for each road section, the equity time difference t3 is subtracted from the actual delay days t1: if t1-t3=0, it means that the work is not responsible for the total delay in the construction period; if t1-t3>0, it means that the work is responsible for the total delay in the construction period; if t1-t3<0, it means that the work is not responsible for the total delay in the construction period, and the work has a time difference donation of |t1-t3| days.

[0019] Optionally, in step 4, for the total time difference calculation formula for each road section, first remove the work that is not responsible for the total delay in the construction period. For the remaining work that is responsible for the total delay in the construction period, subtract the time difference donation from the sum of the number of days their actual delay exceeds their equity time difference, which is the number of days t4 that need to be responsible. The work is responsible for t4 in proportion to the number of days their actual delay exceeds their equity time difference.

[0020] In a second aspect, the present invention provides a computer-readable storage medium storing a computer program, wherein the computer program enables a computer to execute the method for determining the responsibility for delayed construction period based on a dual-code network plan as described in the first aspect.

[0021] In a third aspect, the present invention provides an electronic device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the method for determining the responsibility for delayed construction period based on a dual-code network plan as described in the first aspect is implemented.

[0022] The beneficial effects of the present invention are as follows: based on the total time difference generation mechanism in the dual-code network plan, the present invention utilizes the sharing characteristics of the total time difference, extracts the common essence of the total time difference as the basis for judging the responsibility for delayed construction period, and can overcome the shortcomings of unfairness and subjectivity in judging the responsibility for construction period. For multiple interference events in the dual-code network plan during the same period, a reasonable scheme for judging the responsibility for delayed construction period is effectively proposed, which embodies the principles of fairness and objectivity, can effectively reduce disputes over construction period, and is conducive to the joint completion of engineering tasks.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] The present invention generates a time difference mechanism from the logic unit. According to the properties and functions of the total time difference, it is known that the total time difference of the work is the smallest total time difference of the section. When the section with the smallest total time difference has only one work, it is the total time difference of the work, which is the difference between the continuous working time of the logical key section and the work; when the section with the smallest total time difference has two or more works, the essential meaning of the total time difference of the work is the difference between the continuous working time of the key section in the logic unit and the sum of the duration of all the works in the section. For example Figure 1 The total time difference of work A is 5 (days), which is C-+DAB, i.e., the difference in duration of work. The total time difference of work B is 1 (day), i.e., DB, the difference in duration of work. Obviously, the total time difference of 5 days, i.e., C+DAB, includes the total time difference of work B, i.e., DB, which is 1 day. In this way, there is an inclusion relationship between the total time differences of work A and B.

[0031] In order to compare under the same conditions, a concept, equity time difference, is introduced. In the logical unit, the sum of the duration of each job in the critical section and the sum of the duration of each job in the corresponding non-critical section, the difference between the two sums is called the equity time difference of the non-critical section. If there is only one job on the non-critical section, the difference between the two sums is the equity time difference of the job. 4 days out of 5 days of the total time difference of job A, that is, CA is the direct total time difference of job A, which is the equity time difference of job A. 1 day of the total time difference of job A is the direct total time difference of job B. From the perspective of job A, it belongs to the non-direct total time difference. The total time difference of job A includes the equity time difference of job A and the equity time difference of B, which is the sum of the two. The total time difference of job A includes the total time difference of job B. There is an inclusion relationship between the total time differences of jobs A and B. The total time difference of jobs A and B has no comparative significance. Jobs A and B each exclude the non-direct total time difference and only use the direct total time difference for comparison, which has comparative significance. The total time difference generated by each work is the equity time difference, which is the mechanism of the equity time difference and the real meaning of the equity time difference. Using the equity time difference of the work to judge the delay plan time obviously has an objective standard. Taking the time of the critical line as the coordinate axis, the duration of each work in the network has a one-to-one correspondence with the corresponding interval of the time axis of the critical line. The time difference between the corresponding intervals is the equity time difference of the work. The equity time difference is the only objective existence on the time axis. The equity time difference of the critical work is zero. The equity time difference of the line is equal to the total time difference of the line, which is also equal to the total free time difference of the line. The equity time difference of the line is equal to the sum of the equity time differences of each work on the line. It should be noted that in the network diagram, starting from the starting node, passing through a series of arrows and nodes in sequence along the direction of the arrow, and finally reaching the end point is called a line. In the line, the working path between any two nodes along the direction of the arrow is called a section. There are two sections of road between any two critical nodes. All the work on one section is critical work, which is called a critical section. There is non-critical work on the other section, which is called a non-critical section. The network composed of these two sections is called a network logic unit, which is the basic unit of a complex network.

[0032] In the logical unit, the total time difference of a job is always the smallest among the total time differences of many sections. There are two types of total time differences. The first type is that if there is only one job in the smallest section, the total time difference of the job reflects the corresponding relationship between the duration of the job and the time interval of the corresponding key section. The total time difference of the job is the difference between the two times. The total time difference in this case is called the parent total time difference; the other type is that if there is more than one job in the smallest section, but two or more jobs, the total time difference of a job reflects the corresponding relationship between the sum of the continuous work of the two or more jobs and the corresponding key section time interval. The difference between the key section time interval and the sum of the duration is the total time difference of the job. The total time difference in this case is called the total time difference of all beings. Although they are both the total time differences of a job, there is a clear difference between the parent total time difference and the total time difference of all beings. The total time difference of all beings includes the parent total time difference and the total time difference that is not caused by the duration of the job itself. The total time difference that is not caused by the duration of the job itself is called the non-parent total time difference. The total time difference between parents and children is the common part of the total time difference. The total time difference between parents and children is directly related to the duration of work. The delay of the schedule is actually the change of the duration of work. The total time difference between parents and children is directly related to the delay of the schedule. It is scientific to use the total time difference between parents and children to judge the responsibility of the delay of the schedule. It is actually a judgment of rights and interests. Defining the total time difference between parents and children as the time difference of rights and interests has more direct social significance and is easier for people to accept.

[0033] There are two types of total time difference: the total time difference of biological birth and the total time difference of all living beings. The total time difference of all living beings includes two parts: the total time difference of biological birth and the total time difference of non-biological birth. In order to distinguish the difference between these two kinds of biological birth total time difference, the biological birth total time difference in the total time difference of all living beings is called the self-biological birth total time difference.

[0034] For the work of the total time difference of the biological life, the total time difference of the work can be used by the time difference work of all living beings. The use is conditional. When the total time difference of the biological life is not used or not fully used, and there is a surplus time difference, the surplus time difference in the total time difference of the biological life can be donated to the time difference work of all living beings and used, so as to reduce the responsibility of the total time difference work for overtime. For the work of the total time difference of the biological life, if the delay plan exceeds the total time difference of the biological life, it is an overstepping of authority. The excess time is the total time delay responsibility time. If it is less than or equal to the total time difference of the biological life, it is not an overstepping of authority and there is no total time delay responsibility.

[0035] For the work of the total time difference of all living beings, if the delay plan is less than or equal to the total time difference of one's own life, there is no responsibility for the total construction period. Under the condition of delaying the total construction period, if the delay plan of the total time difference of all living beings is greater than the total time difference of one's own life, if there is no donated time difference to be transferred and accepted for the total time difference of all living beings, the time exceeding the total time difference of one's own life is the responsibility time for the total delay of the total time difference of all living beings; when there is a donated time difference to be accepted for the total time difference of all living beings, the time when the delay plan time exceeds the sum of the accepted time difference and the total time difference of one's own life of the total time difference of all living beings is the responsibility time for the total delay of the total time difference of all living beings.

[0036] According to the role of the node, the expression meaning of the road section is divided into: the road section is divided into the full time difference section, the free time difference section, the total time difference section, etc. Among them, there is a type of road section, which starts from the total time difference node and can neither express the total time difference nor the free time difference. For example Figure 2 The middle section ②-⑧ was once considered "meaningless". Using the concept of equity time difference, the comparison result of section ②-⑧ and the corresponding key section is the equity time difference of work B. Section ②-⑧ can express the equity time difference of work B, which is called the equity time difference section. The equity time difference section has been added to the classification of the meaning of logical sections in the network, which is a small step forward in the understanding of the network. For the case of negative equity time difference, use the virtual work judgment method, remove the virtual work, and allocate it proportionally. For example Figure 5 , the equity time difference of work A and B is 1 / 3 and 2 / 3 (days) respectively.

[0037] For example Figure 1 The equity time difference between jobs A and B is 4 and 1 (days) respectively. Figure 2 The equity time difference between jobs A and B is 4 and 1 (days) respectively. Figure 3 The equity time difference of work A and B is (6+4-2-3)×2÷(2+3)=2(days) and (6+4-2-3)×3÷(2+3)=3(days) respectively. The equity time difference of work A and B is allocated according to the proportion of work duration. The equity time difference of work A and B is allocated according to the proportion of work duration according to the definition and the part established by the network. Figure 4 The equity time difference between jobs A and B is 4 and 1 (days) respectively.

[0038] Equity time difference has many forms. Figure 1 , the equity time difference of work A is equal to the free time difference; the equity time difference of work B is equal to the total time difference, which is also equal to the free time difference. Figure 2 The equity time difference of work A is equal to the total time difference; the equity time difference of work B is equal to a part of the total time difference, that is, the time interval of the key section mapped by the continuous working time of work B and the difference between the continuous working time of work B, that is, DB = 4-3 = 1 (day), that is, the biological total time difference of work B. The equity time difference of a work is not greater than the total time difference of the work. The equity time difference has many forms, such as total time difference, free time difference, part of total time difference, part of free time difference, relative time difference, etc. In different network environments, work equity has different forms.

[0039] Although equity time difference has many forms, they all have a common attribute. The duration of the work is mapped to the corresponding critical path time interval. The difference between them is the equity time difference. This is the essence of the definition of equity time difference - the original total time difference. This definition is for when the work has a common total time difference, such as Figure 3For tasks A and B, the time difference is determined by the logical relationship in the network, for example Figure 1 , Figure 2 , Figure 4 The time difference between the rights and interests of tasks A and B reflects the objectivity of the time difference between rights and interests.

[0040] For the established network, the equity time difference established according to the logical section in the logical unit has a one-to-one correspondence with the work, and is objective and unique. The objectivity and uniqueness of the equity time difference are also the reasons why the present invention establishes the equity time difference of the work as the criterion for judging the responsibility for delaying the total construction period. In a logical section, when there are multiple works that are delayed at the same time, the division of responsibilities for the delay results is based on the equity time difference. Whoever generates the time difference will benefit, whoever works more will get more, and the principle of mutual assistance in terms of interests, whoever exceeds the authority will be responsible, and the more the authority is exceeded, the more responsibilities will be, so the respective responsibilities can be clarified. For example Figure 1 Jobs A and B were delayed by 6 days and 1 day respectively, jobs A and B were delayed by 7 days and 0 days respectively, and A and B were delayed by 7 days and 2 days respectively. Figure 1 The key routes are ①-②-⑧, the key tasks are C and D, the total construction period is 10 (days), A (5, 4) days, B (1, 1) day. Labeling instructions: Work name (total time difference, equity time difference) days. Figure 1 The total time difference calculation formula for the logical section is: A+B=5 (days), B=1 (day).

[0041] The first case: because 6+1=7>5 (days), the total construction period will exceed 7-5=2 (days). Whoever has the equity time difference will enjoy it. Work A enjoys 4 days and Work B enjoys 1 day. Among them, Work A delays the total construction period: 6 (A delay plan)-4 (A equity time difference)=2 (days). Work B delays the total construction period: 1 (B's delay plan)-1 (B's equity time difference)=0, so Work B does not delay the total construction period. The responsibility for the 2-day delay in the total construction period is borne entirely by Work A, and Work B is not responsible. When two works are located on the same logical unit non-critical section, the two works have a shared interest in the total time difference of the section, and the shared basic interest is their respective equity time difference. Whoever exceeds the authority shall bear the responsibility. Work A exceeds the authority by 2 days, and Work A bears the responsibility for exceeding the authority of the section. The total construction period is delayed by 2 days, and Work A bears all the responsibility.

[0042] The second case: Since 7+0==7>5 (days), the total construction period is exceeded by 7-5=2 (days). Among them, the total construction period of work A is delayed by: 7 (A's delay plan)-4 (A's equity time difference)+1 (B's equity time difference)=2 (days). The total construction period of work B is delayed by: 0 (B's delay plan)-1 (B's equity time difference)=-1<0, so work B does not delay the total construction period. The responsibility for the 2-day delay in the total construction period is borne entirely by work A, and work B is not responsible. When two tasks are located on the same logical unit non-critical section, the two tasks have a shared interest in the total time difference of the section, and the basic shared interest is their respective equity time difference. However, when the equity time difference of a task is not fully or partially utilized, the task can carry forward the spirit of mutual assistance and friendship among "colleagues" and donate it to another task, so that the time difference can be fully utilized and the benefits of the time difference can be fully utilized, so that the "colleagues" can reduce the responsibility for delaying the total construction period. Job A enjoyed the 1-day time difference donated by "colleague" B and only exceeded the authority by 2 days. Job A bears full responsibility for the 2-day total construction delay caused by the network.

[0043] The third case: Since 7+2==9>5 (days), the total construction period is exceeded by 9-5==4 (days). Among them, the total construction period of work A is delayed by 7 (A's delay plan)-4 (A's equity time difference)=3 days, and the total construction period of work B is delayed by 2 (B's delay plan)-1 (B's equity time difference)=1 (day). The total construction period is delayed by 4 days, and work A and B are jointly responsible, among which work A is responsible for delaying the total construction period by 3 days, and work B is responsible for delaying the total construction period by 1 day. The total construction period is delayed together, and both parties bear the responsibility together, but each party bears its own share of responsibility.

[0044] Through this example, the total time difference is classified into the following categories: total time difference of all beings and total time difference of relatives according to the role of nodes, the classification significance of logical sections, the significance of virtual work and the existence conditions using the mechanism of logical unit time difference. The total time difference of all beings is divided into total time difference of relatives and total time difference of non-relatives. Using the common part of the total time difference: the total time difference of relatives, as the judgment standard equity time difference, consider the full utilization of the transfer of the total time difference of non-relatives, and divide the responsibilities and rights when multiple interference events occur. It reflects the principle that whoever generates the time difference will benefit, whoever works more will get more, mutual assistance in interest conditions, whoever exceeds the authority will be responsible, and the principle that the more the authority exceeds, the more the responsibility is, which is fair, just and objective. It is simple to understand and convenient to operate. By adopting this method, disputes over the responsibility of the construction period can be quickly settled, so that the parties can jointly fulfill their respective contractual responsibilities and complete the engineering tasks together.

[0045] Commonly used double-code network diagram logic unit models such as Figure 1 , 2 , 3, 4, most networks are a combination of these network logic unit models.

[0046] Figure 1In the above table, suppose the total time difference of work A is m (days), m>0, the total time difference of work B is n (days), n>0, mn>0, then the equity time difference of work A is mn, the equity time difference of work B is n, and the division of responsibility for delayed work is shown in Table 1.

[0047] Table 1 Delayed work responsibility division model 1

[0048]

[0049] Figure 2 In , suppose the total time difference of work A is m (days), m>0, the total time difference of work B is n (days), n>0, nm>0, then the equity time difference of work A is m, the equity time difference of work B is nm, and the division of responsibility for delayed work is shown in Table 2.

[0050] Table 2 Delayed work responsibility division model 2

[0051]

[0052] Figure 3 In the above table, suppose the total time difference of work A is m (days), m>0, and the working durations of work A and B are a and b (days) respectively. Then, the total time difference of work B is m (days). Then, the equity time difference of work A is ma / (a+b) (days), and the equity time difference of work B is mb / (a+b). The division of responsibility for delayed work is shown in Table 3.

[0054]

[0055]

[0056] Figure 4 In , suppose the total time difference of work A is m (days), m>0, and the total time difference of work B is n (days), n>0, then the equity time difference of work A is m (days), and the equity time difference of work B is n (days). The division of responsibility for delayed work is shown in Table 4.

[0057] Table 4 Delayed work responsibility division model 4

[0058]

[0059] The above model can be used to quickly answer the problem of determining the responsibility for delay in construction period based on network planning when multiple events occur at the same time. This method can be applied to claims for construction period in a double-code network.

[0060] In one embodiment, the present invention proposes a method for determining the responsibility for delayed construction period based on a double-code network plan, which is applied to claims for construction period. For example, at a certain building construction site, the independent foundation segmented construction process is foundation excavation A, steel bar binding B, formwork C, and concrete pouring D; it is divided into four sections for sequential construction, and the duration of each section is shown in Table 5; based on this condition requirement, a double-code network construction plan was formulated. One day, the construction plan was checked and it was found that work A2 was delayed for 2 days due to drawing changes, work A3 was delayed for 2 days due to geological exploration reasons, work B4 was delayed for 1 day due to unqualified steel bar binding quality, work C2 was delayed for 1 day due to inadequate construction organization personnel, work D2 was delayed for 3 days due to typhoons, and work D3 was delayed for 2 days due to the epidemic. According to the above conditions, the total delay responsibility is determined, and the contractor can calculate the claimable construction period.

[0063]

[0064] The steps to apply this method to time claims are as follows:

[0065] 1. Draw a double-code network plan, calculate the working duration of each line, find out the key lines and key tasks, and mark the key lines with thick lines, such as Figure 6 shown.

[0083] A1+B1+C1+C2+C3+D3+D4=4+5+3+4+5+3+4=28 (days); (18)

[0084] A1+B1+C1+C2+D2+D3+D4=4+5+3+4+3+3+4=26 (days); (19)

[0085] A1+B1+C1+D1+D2+D3+D4=4+5+3+5+3+3+4=27 (days). (20)

[0086] Because work (12) lasts the longest, the critical path is: A1+B1+B2+B3+C3+C4+D4, and the critical tasks are: A1, B1, B2, B3, C3, C4, D4. The total time difference and free time difference of the critical tasks are zero. Use a bold line to mark the critical path.

[0087] 2. Subtract the working duration of each non-critical working line from the working duration of the critical working line, and remove the critical work in each formula to obtain the following total time difference calculation formula for the section.

[0088] A2+A3+A4+B4=5(days); (1-1)

[0089] A2+A3+B4=4(days); (2-1)

[0090] A2+A3=3(days); (3-1)

[0091] A2+A3+D3=4(days); (4-1)

[0092] A2+B4=3(days); (5-1)

[0093] A2=2(days); (6-1)

[0102] C2+D2+D3=4(days); (16-1)

[0103] C1+C2=2(days); (17-1)

[0104] C1+C2+D3=3(days); (18-1)

[0105] C1+C2+D2+D3=5(days); (19-1)

[0106] C1+D1+D2+D3=4 (days). (20-1)

[0107] 3. Find the total time difference of each task.

[0108] In the calculation formula for the sections from (1-1) to ξ11-1), (13-1) to (20-1) or the combined sections, the total time difference of each work takes the minimum value, and the total time differences of works A2, A3, A4, B4, C1, C2, D1, D2, and D3 are 2, 3, 5, 1, 2, 1, 4, 4, and 1 (days) respectively.

[0109] 4. Calculate the equity time difference for each job.

[0110] The equity time difference of key tasks A1, B1, B2, B3, C3, C4, and D4 is zero.

[0111] In the logical unit ②-③-⑤+②-④-⑤, the time interval of the key task B1 corresponding to task A2 is 5 days, so the equity time difference of task A2 is 5-3=2 (days);

[0112] In the logic unit ②-③-⑤-⑦-⑩+②-④-⑨-⑩, after the equity time difference of work A2 is established, the time interval between work A3 and key work B2 is 4 days, and the equity time difference of work A3 is 4-3=1 (day);

[0113] In the logic unit In the example, the time interval of the key task C3 corresponding to task B4 is 5 days, and the equity time difference of task B4 is 5-4=1 (day);

[0114] In the logic unit In the example, after tasks A2, A3, and B4 are established, the time interval of key task B3 corresponding to task A4 is 5 days, so the equity time difference of task A4 is 5-4=1 (day);

[0115] In the logic unit In the example, the time interval of the key task C4 corresponding to task D3 is 4 days, so the equity time difference of task D3 is 4-3=1 (day);

[0116] In the logic unit In the example, the time interval of the key task B3 corresponding to task C2 is 5 days, so the equity time difference of task C2 is 5-4=1 (day);

[0117] In the logic unit In the example, after the equity time difference of work C2 is established, the time interval of key work B2 corresponding to work C1 is 4 days, so the equity time difference of work C1 is 4-3=1 (day);

[0118] In the logic unit In the example, after tasks C2 and D3 are established, the time interval of key task C3 corresponding to task D2 is 5 days, so the equity time difference of task D2 is 5-3=2 (days);

[0119] In the logic unit In the example, after tasks C1, D2, and D3 are established, the time interval of key task B3 corresponding to task D1 is 5 days, so the equity time difference of task D1 is 5-5=0 (days).

[0120] The equity time difference of jobs A1, A2, A3, A4, B1, B2, B3, B4, C1, C2, C3, C4, D1, D2, D3, and D4 are A1(0), A2(2), A3(1), A4(1), B1(0), B2(0), B3(0), B4(1), C1(1), C2(1), C3(0), C4(0), D1(0), D2(2), D3(1), and D4(0) (days). Note: Job name (equity time difference).

[0121] 5. The list shows the total time difference and equity time difference of each job.

[0122] The total time difference and equity time difference of each job are: A1(0,0), A2(2,2), A3(3,1), A4(5,1), B1(0,0), B2(0,0), B3(0,0), B4(1,1), C1(2,1), C2(1,1), C3(0,0), C4(0,0), D1(4,0), D2(4,2), D3(1,1), D4(0,0) (days). Note: Job name (total time difference, equity time difference) (days).

[0123] 6. Use the calculation results of the dual-code network plan to determine the impact and responsibility of work delays on the total construction period.

[0124] The calculation results of the dual-code network plan should include:

[0125] (1) The key route is: A1+B1+B2+B3+C3+C4+D4.

[0126] (2) Key tasks are: A1, B1, B2, B3, C3, C4, D4.

[0127] (3) Calculation formula for total time difference of logical section:

[0128] A2+A3+A4+B4=5(days); (1-1)

[0129] A2+A3+B4=4(days); (2-1)

[0130] A2+A3==3(days); (3-1)

[0131] A2+A3+D3=4(days); (4-1)

[0132] A2+B4=3(days); (5-1)

[0133] A2=2(days); (6-1)

[0134] A2+D3=3(days); (7-1)

[0135] A2+C2=3(days); (8-1)

[0136] A2+C2+D3=4(days); (9-1)

[0137] A2+C2+D2+D3=6(days); (10-1)

[0138] B4=1(day); (11-1)

[0139] D3=1(day); (13-1)

[0140] C2=1(day); (14-1)

[0141] C2+D3=2(days); (15-1)

[0142] C2+D2+D3=4(days); (16-1)

[0143] C1+C2=2(days); (17-1)

[0144] C1+C2+D3=3(days); (18-1)

[0145] C1+C2+D2+D3=5(days); (19-1)

[0146] C1+D1+D2+D3=4 (days). (20-1)

[0147] (4) The total time difference and equity time difference of each job are: A1(0,0), A2(2,2), A3(3,1), A4(5,1), B1(0,0), B2(0,0), B3(0,0), B4(1,1), C1(2,1), C2(1,1), C3(0,0), C4(0,0), D1(4,0), D2(4,2), D3(1,1), D4(0,0) (days).

[0148] First, use the logical section total time difference calculation formula to determine the impact of delays of 2 days, 2 days, 1 day, 1 day, 3 days, and 2 days on the total construction period for work A2, A3, B4, C2, D2, and D3.

[0149] Tasks A2, A3, B4, C2, D2, and D3 are delayed by 2 days, 2 days, 1 day, 1 day, 3 days, and 2 days, respectively, which can be expressed as A2=2, A3=2, B4=1, C2=1, D2=3, and D3=2.

[0150] The non-critical tasks without delay plan are A4, C1, and D1, which are represented by A4=0, C1=0, and D1=0.

[0151] Substitute the work without delay plan A4=0, C1=0, D1=0 and the work with delay plan A2=2, A3=2, B4=1, C2=1, D2=3, D3=2 into the left side of the total time difference calculation formula of the logical section, compare the calculation result with the number on the right side, and judge whether the total construction period is delayed or not:

[0152] A2+A3+A4+B4=2+2+0+1=5=5 (days), the total construction period is normal; (1-2)

[0153] A2+A3+B4=2+2+0=4=4 (days), the total construction period is normal; (2-2)

[0154] A2+A3=2+2=4>3(days), the total construction period is delayed by 1 day; (3-2)

[0155] A2+A3+D3=2+2+2=6>4(days), the total construction period is delayed by 2 days; (4-2)

[0156] A2+B4=2+1=3=3 (days), the total construction period is normal; (5-2)

[0157] A2=2=2(days), the total construction period is normal; (6-2)

[0158] A2+D3=2+2=4>3(days), the total construction period is delayed by 1 day; (7-2)

[0159] A2+C2=2+1=3=3 (days), the total construction period is normal; (8-2)

[0160] A2+C2+D3=2+1+2=5>4(days), the total construction period is delayed by 1 day; (9-2)

[0161] A2+C2+D2+D3=2+1+3+2=8>6(days), the total construction period is delayed by 2 days; (10-2)

[0162] B4=1=1(day), the total construction period is normal; (11-2)

[0163] D3=2>1(day), the total construction period is delayed by 1 day; (13-2)

[0164] C2=1=1(day), the total construction period is normal; (14-2)

[0165] C2+D3=1+2=3>2(days), the total construction period is delayed by 1 day; (15-2)

[0166] C2+D2+D3=1+3+2=6>4(days), the total construction period is delayed by 2 days; (16-2)

[0167] C1+C2=0+1=1<2(days), the total construction period is normal; (17-2)

[0168] C1+C2+D3=0+1+2=3=3(days), the total construction period is normal; (18-2)

[0169] C1+C2+D2+D3=0+1+3+2=6>5(days), the total construction period is delayed by 1 day; (19-2)

[0170] C1+D1+D2+D3=0+0+3+2=5>4(days), the total construction period is delayed by 1 day. ξ20-2)

[0171] The relationship between the total construction period delay is (3-2), (4-2), (7-2), (9-2), (10-2), (13-2), (15-2), (16-2), (19-2), (20-2); the related tasks are: A2, A3, C1, C2, D1, D2, D3, among which tasks C1 and D1 are known conditions and have no delay plan, so they are discarded. The tasks that delay the total construction period are: A2, A3, C2, D2, D3.

[0172] Secondly, use the equity time difference to determine the responsibility for delaying the total construction period.

[0173] From (3-2), we can see that work A2 and A3 jointly delay the total construction period by 1 day. Since the equity time difference of A2 and A3 is 2 and 1 (days) respectively, 2-2==0 (days), 2-1=1 (days), work A2 is not responsible for the delay of the total construction period by 1 day, and work A3 bears the full responsibility for the delay of the total construction period by 1 day.

[0174] From (4-2), we can see that tasks A2, A3, and D3 jointly delay the total construction period by 2 days. Since the equity time differences of A2, A3, and D3 are 2, 1, and 1 (days) respectively, 2-2=0 (days), 2-1=1 (days), and 2-1=1 (days), task A2 is not responsible for the 2-day delay in the total construction period, and tasks A3 and D3 are each responsible for 1 day of the 2-day delay in the total construction period.

[0175] From (7-2), we can see that work A2 and D3 jointly delay the total construction period by 1 day. Since the equity time difference of A2 and D3 is 2 and 1 (days) respectively, 2-2=0 (days), 2-1=1 (day), work A2 is not responsible for the delay of the total construction period by 1 day, and work D3 bears full responsibility for the delay of the total construction period by 1 day.

[0176] From (9-2), we can see that work A2, C2, and D3 jointly delay the total construction period by 1 day; since the equity time difference of A2, C2, and D3 is 2, 1, and 1 (days) respectively, 2-2=0 (days), 1-1=0 (days), and 2-1=1 (day), work A2 and C2 are not responsible for the delay of the total construction period by 1 day, and work D3 bears full responsibility for the delay of the total construction period by 1 day.

[0177] From (10-2), we can see that work A2, C2, D2, and D3 jointly delay the total construction period by 2 days; since the equity time difference of A2, C2, and D3 are 2, 1, 2, and 1 (days) respectively, 2-2=0 (days), 1-1=0 (days), 3-2=1 (days), and 2-1=1 (days), work A2 and C2 are not responsible for the 2-day delay in the total construction period, and work D2 and D3 are responsible for 1 day of the 2-day delay in the total construction period respectively.

[0178] From (13-2), we can see that work D3 delays the total construction period by 1 day, and work D3 bears full responsibility for the delay of 1 day in the total construction period.

[0179] From (15-2), we can see that work C2 and D3 jointly delay the total construction period by 1 day; because the equity time difference of C2 and D3 is 1 and 1 (days) respectively, 1-1=0 (days), 2-1=1 (days), work C2 is not responsible for the delay of the total construction period by 1 day, and work D3 bears full responsibility for the delay of the total construction period by 1 day.

[0180] From (16-2), we can see that tasks C2, D2, and D3 jointly delay the total construction period by 2 days; since the equity time differences of C2, D2, and D3 are 1, 2, and 1 (days) respectively, 1-1=0 (days), 3-2=1 (days), and 2-1=1 (days), task C2 is not responsible for the 2-day delay in the total construction period, and tasks D2 and D3 are each responsible for 1 day of the 2-day delay in the total construction period.

[0181] From (19-2), we can see that tasks C1, C2, D2, and D3 together delay the total construction period by 1 day. Since the equity time differences of tasks C1, C2, D2, and D3 are 1, 1, 2, and 1 (days) respectively, 0-1=-1<0 (task C1 has no delay plan and has 1 day of equity time difference to donate), 1-1=0 (day), 3-2=1 (day), and 2-1=1 (day). Work C1 is not responsible for the one-day delay in the total construction period, because there is no delay plan, and is not responsible for the one-day delay in the total construction period; although work C2 is delayed, it is not responsible for the one-day delay in the total construction period because it does not exceed the equity time difference; work D2 and D3 are delayed by one day each exceeding the equity time difference, because work C1 has one day of equity time difference donation, the responsibilities of work D2 and D3 can offset one day, so they are jointly responsible for the one-day delay in the total construction period, and the responsibilities they bear are shared in proportion to the amount of their own equity time difference, following the principle of exceeding the authority and making more mistakes, and bearing more responsibilities. 1÷(1+1)=0.5(days), so work D2 and D3 are each responsible for 0.5 days of the one-day delay in the total construction period.

[0182] From (20-2), we can see that work C1, D1, D2, and D3 jointly delay the total construction period by 1 day. Since work C1 and D1 have no delay plan, they are not responsible for the 1-day delay of the total construction period. The equity time difference of work C1, D1, D2, and D3 is 1, 0, 2, and 1 (days) respectively. Since 0-1=-1<0 (days), work C1 has no delay plan and has 1 day of equity time difference to donate. ) 0-0=0(days), 3-2=1(days), 2-1=1(days). Work C1 is not responsible for the one-day delay in the total construction period, because there is no delay plan, so it is not responsible for the one-day delay in the total construction period; Work D1 has no delay plan, and it has not exceeded the equity time difference, so it is not responsible for the one-day delay in the total construction period; Works D2 and D3 have delay plans that exceed the equity time difference by one day, and because Work C1 has one day of equity time difference donation, the responsibilities of Works D2 and D3 can offset one day, so they are jointly responsible for the one-day delay in the total construction period, and the responsibilities they bear are proportionally shared according to the amount of their own equity time difference, following the principle of exceeding the authority and making more mistakes, and bearing more responsibilities. 1÷(1+1)=0.5(days), so Works D2 and D3 are each responsible for 0.5 days of the one-day delay in the total construction period.

[0183] To sum up, tasks A3, D2, and D3 are each responsible for delaying the total construction period by 1 day, and together delay the total construction period by 2 days.

[0184] 7. Calculate the contractor’s claim period based on the contractor’s responsibility for the total delay in the construction period.

[0185] Work A3, D2, and D3 are each responsible for delaying the total construction period by 1 day, which together delays the total construction period by 2 days; and work A3 is delayed by 2 days due to geological exploration reasons, which is the contractor's fault and the construction period can be claimed; work D2 is delayed by 3 days due to typhoons and work D3 is delayed by 2 days due to the epidemic, which are force majeure reasons and the construction period can be claimed; comprehensively speaking, the contractor can claim for 2 days of construction period.
