5.2.2  SCI Calculation

5.2.2.1  SCImain in respect of a Road Section Length on the Strategic Route and [Main Distributor Network] is calculated in accordance with the following:

(a)  each Road Section Length shall be divided into 20m subsections;

(b)  where [DVI] is used each defect or patch identified in a subsection shall:

(i)  be assigned as either a "Minor Deterioration" or a "Major Deterioration" in accordance with Table 11.13;

(ii)  be assigned a "percentage defect area" as set out in the UKPMS extent code;

(iii)  no subsection shall have a percentage defect area greater than 100%; and

(iv)  allocate patch percentage;

(c)  each subsection shall be assigned the appropriate score from Table 11.7;

(d)  the score allocated in accordance with paragraph 5.2.2.1(c) will then be multiplied by the length of relevant surveyed subsection;

(e)  the result of the multiplication carried out in respect of each 20m subsection in accordance with paragraph 5.2.2.1(d) shall be added together in respect of all surveyed subsections in the [RSL] and this sum shall then be divided by the total length of that [RSL] as set out in the Network Model.

5.2.2.2  SCIsec in respect of a Road Section Length as the Secondary Distributor Network is calculated in accordance with the following:

(a)  each Road Section Length shall be divided into 20m subsections;

(b)  where [DVI] is used each defect or patch identified in a subsection shall:

(i)  be assigned as either a "Minor Deterioration" or a "Major Deterioration" in accordance with Table 11.13;

(ii)  be assigned a "percentage defect area" as set out in the UKPMS extent code;

(iii)  no subsection shall have a percentage defect area greater than 100%; and

(iv)  allocate a patch percentage;

(c)  each subsection shall be assigned the appropriate score from Table 11.8;

(d)  the score allocated in accordance with paragraph 5.2.2.2(c) will then be multiplied by the length of relevant surveyed 20m subsection;

(e)  the result of the multiplication carried out in respect of each 20m subsection in accordance with paragraph 5.2.2.2(d) shall be added together in respect of all surveyed subsections in the [RSL] and this sum shall then be divided by the total length of that [RSL] as set out in the Network Model.

5.2.2.3  SCIlink in respect of a Road Section Length as the Link Road Network is calculated in accordance with the following:

(a)  each Road Section Length shall be divided into 20m subsections;

(b)  where [DVI] is used each defect or patch identified in a subsection shall:

(i)  be assigned as either a "Minor Deterioration" or a "Major Deterioration" in accordance with Table 11.13;

(ii)  be assigned a "percentage defect area" as set out in the UKPMS extent code;

(iii)  no subsection shall have a percentage defect area greater than 100%; and

(iv)  allocate a patch percentage;

(c)  each subsection shall be assigned the appropriate score from Table 11.9;

(d)  the score allocated in accordance with paragraph 5.2.2.3(c) will then be multiplied by the length of relevant surveyed subsection;

(e)  the result of the multiplication carried out in respect of each 20m subsection in accordance with paragraph 5.2.2.3(d) shall be added together in respect of all surveyed subsections in the [RSL] and this sum shall then be divided by the total length of that [RSL] as set out in the Network Model.

5.2.2.4  SCIlocal in respect of a Road Section Length as the [Local Access Road Network] is calculated in accordance with the following:

(a)  each Road Section Length shall be divided into 20m subsections;

(b)  where [DVI] is used each defect or patch identified in a subsection shall:

(i)  be assigned as either a "Minor Deterioration" or a "Major Deterioration" in accordance with Table 11.13;

(ii)  be assigned a "percentage defect area" as set out in the UKPMS extent code;

(iii)  no subsection shall have a percentage defect area greater than 100%; and

(iv)  allocate a patch percentage;

(c)  each subsection shall be assigned the appropriate score from Table 11.10;

(d)  the score allocated in accordance with paragraph 5.2.2.4(c) will then be multiplied by the length of relevant surveyed subsection;

(e)  the result of the multiplication carried out in respect of each subsection in accordance with paragraph 5.2.2.4(d) shall be added together in respect of all surveyed subsections in the [RSL] and this sum shall then be divided by the total length of that [RSL] as set out in the Network Model.
