ANNEXURE-1

1. Introduction: Ensuring the quality of road/bridge works is the responsibility of the Government of Andhra Pradesh who are implementing various programmes/projects, a two tier quality control mechanism is envisaged. The first tier is in-house quality control by the executive agencies (PIU, PRI, PR) and the contractor as per the agreement conditions and its primary function is to ensure quality control through enforcement of technical standards. Under the second tier of the quality control mechanism, periodic inspections are required to be carried out by the EEs/ DyEEs of V&QC wing and its main function is to monitor the quality and effectiveness of the enforcement process. In view of ensuring further uniformity in reporting and better monitoring of the performance of second tier of quality monitoring, it has now been decided to prescribe detailed guidelines and reporting formats for this tier. The functions of Second Tier Quality Control Mechanism: Checks to ensure that the first tier is properly

operational. Independent quality tests to verify that the quality

control system is achieving its intended objectives. Detection of systemic flaws in the quality control

process and action to improve the process. Independent supervision of deterrent and punitive

measures in respect of the First Tier and the contractor.

For the time being, these guidelines are being restricted to the works of value Rs. 50.00 Lakhs and above. These guidelines are not applicable for PMGSY works.

4 Grading of Works:

a) Upon inspection of Road/bridge work, the quality of every item and sub item of work would be evaluated by the EE/Dy.EE(V&QC) on the basis of methods of observations prescribed. The grading of work would be done with an intention to quantify the observations showing level of satisfaction in relation to prescribed specifications of the work/item under observation. The grading would be recorded in every item and abstracted at appropriate space provided in Part II of Annexure I.

b) The objective of the grading is to indicate to the PIU/PRI/PR that whether the material or workmanship is acceptable, or unacceptable. If the item is unacceptable, the improvement could be done by either replacement of the entire material/portion of work or by rectification in workmanship or material. Therefore, based on the type of item and method of observation, each item/ sub-item of work would be graded in any of the categories indicated as ‘Satisfactory (S)’,

4

‘satisfactory but requires improvement (SRI) or ‘Unsatisfactory(U)’ as prescribed.

c) Based on grading, the PIU/PRI/PR shall take action for rectification of defect by replacement ,therefore, it is very important to record the defect as well as the suggestive method by which the rectification could be done. The EE/Dy.EE (V&QC) shall record, in the space provided in Part II observation sheet, the grade as well as clear and express reasons for grading the item of work as ‘SRI’ or ‘U’ along with his suggestions for improvement. The reasons and suggestions shall be recorded clearly in such a way that there are no ambiguities or contradictions with observations in other items.

5. Observations by EE/Dy.EE(V&QC) : The detailed method of making observations and grading of item/sub-item of works is given in paragraphs below.

If the above items have been carried out partially, ‘SRI’ grade would be awarded, otherwise, if the above items have not been properly executed, ‘U’ grade would be awarded.

III) Quality Control Arrangements and Attention to Quality: As per the contract, the contractor is required to establish the field laboratory for conducting mandatory quality control tests for material and workmanship. The EE/DyEE

6

(V&QC) is expected to check whether the requisite equipments for the testing of various item(s) of works ongoing at the time of inspection are there in the laboratory or not. This is also required to be seen that whether equipments are being used to actually testing material and workmanship and clear observations on this aspect are to be recorded. EE/DyEE(V&QC) is required to list out various items of works and quantities executed. Based on the prescription about mandatory tests, the EE/DyEE (V&QC) shall also list out various tests and their numbers for each item of work executed by the PIU/PRI/PR. It is mandatory to maintain the Quality Control Register Part-I & II. In case of ongoing works the EE/DyEE(V&QC) is expected to see, as to whether, appropriate entries in the abstract of Quality Control Register have been made, whether, test results for all the items of work executed upto the time of inspection are available in the Quality Control Register (Part-I). In Quality Control Register (Part-II) it is required to be seen that whether record of non-conformance is being maintained and whether appropriate non-conformance report have been issued.

Frequency: At all stages of inspection, the EE/DyEE(V&QC)shall check the above aspects and record his observations.

Grading: If field laboratory with sufficient equipments has been established and equipments are being used, record of tests is properly maintained and monitored through Quality Control Register Part I and II, all the tests as per prescribed frequency have been carried out ‘S’ grade would be awarded. If, any of the above items have been partly attended ‘SRI’ grade would be awarded and if, any of these items have not been attended by PIU/PRI/PR ‘U’ grade would be awarded.

IV) Geometrics: Under this item, the observations about road land width, road way width, carriage way width are required to be made and reported at various stages of construction at selected Reaches. Geometrical features such as camber, super elevation, horizontal curves, requisite transition curves and extra widening are required to be provided right from the levels of the sub-grade up to construction of bituminous layer. However, the observations about these geometric elements shall be recorded by the EE/DyEE(V&QC) in each stage of

7

inspection. If, it is felt that the provisions about camber, super-elevation, extra widening etc. has not been made in DPR/Estimate but are required as per field conditions, in such cases, clear observations should be made in the space provided under ‘General Observations’ at the end of reporting format.

Frequency: At all stages of inspection, the EE/Dy.EE(V&QC)shall check the above aspect at a frequency of 2 per km except for super-elevation and extra widening at curves, which would be checked on at least 1 curve in each km and record his observations.

Grading: If the all the items of geometrics have been executed properly asprovided in DPR/estimate, ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded.

V) Earthwork: The road may be in either cutting (or) in embankment (or) there may be a combination of cutting and embankment in the same road. The observations about the quality are to be made for all the above types of works.

(a) Earthwork in Embankment and Sub-grade: For embankments and sub-grade, the following parameters are critical to quality of material and workmanship:

• Quality of Soil used in embankment or sub-grade (Soil Classification,)• Compaction of embankment or sub-grade.• Side slopes and profile upon completion. The EE/DyEE(V&QC) would be required to ascertain conformance of above parameters with the specifications. Appropriate hand-feel test for soil classification and test for field density at various levels of embankment are expected while the work is ongoing. These observations can also be made by digging appropriate pit in cases where embankment has been completed and the work of sub-base and base-course is ongoing. The EE/DyEE(V&QC) is expected to make the above observations while the work in this item is ongoing. If, execution of this item has been completed and somehow the sufficient observations had not been made during the execution of this item, the EE/DyEE(V&QC) shall make observations about this item by digging pit after completion of embankment.

8

Frequency: The EE/DyEE(V&QC) shall perform the tests as given below:

TYPE FREQUENCYVisual Classification of Soil at Sub-grade

In stage-I, minimum (1) test for earthwork in each half km (irrespective of the executed quantity)

Degree of Compaction of sub-grade

In stage-I, minimum (1) test for each half km length or part thereof (irrespective of the executed quantity)

Side Slopes Profile Minimum (1)per half km in stage –III/IV Grading: Material – If suitable soil has been used, ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded. Compaction – If degree of compaction is within the prescribed limits ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded. Side Slopes – In case work is nearing completion or has been completed and if side slopes and profile is as per provisions ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded.

(b) Earthwork in Cutting: The roads in hilly areas and rolling terrain may have earthwork in cutting. The following parameters are Critical to quality of earthwork in cutting:• Longitudinal gradient and• Slopes of cutting and stability.• Adequacy of slope protection• In case of only formation cutting, dressing and traffic worthiness of completed formation. The EE/DyEE(V&QC) is expected to make clear observations on the basis of actual recording of levels in the stretches fairly representative of the overall quality.

TYPE FREQUENCYStability and workmanship of Slope of Cuttings

At all stages of inspection in case of work of formation cutting- Minimum two critical locations with maximum height in each KM stretch of road (irrespective of the executed

9

quantity).In case of hill road having formation cutting and pavement work, the above observation would be made at those stages of inspection when formation cutting work is ongoing.

Adequacy of slope protection If formation cutting is complete, dressing and traffic worthiness of formation

At stage –III and stage IV - minimum two critical locations with maximum height in each KM stretch of road (irrespective of the executed quantity).

Recording of Longitudinal Levels

At all stages of inspection in case of work of formation cutting-In a critical and fairly representative stretch of 200 meters in each KM (irrespective of the executed quantity).In case of hill road having formation cutting and pavement work, the above observation would be made at those stages of inspection when formation cutting work is ongoing.

Grading: If the longitudinal gradient and slope of cutting is as per provisions having adequate stability, ‘S’ grade would be awarded, if improvement is possible with respect to slope and stability of cuts, ‘SRI’ grade would be awarded, otherwise ‘U’ grade would be awarded.

VI) Sub-Base Course and Shoulders: Specifications provide for course gradedgranular sub-base for rural roads. Recently, gravel sub-base has also been allowed. For monitoring the quality of GSB, the following quality parameters are critical:• The conformance of the material to grading requirements and also to ensure that soil fraction passing through 75 micron sieve is not more than the prescribed percentage.• Plasticity characteristics of the fraction passing through 425 micron sieve are well within the prescribed limits.• Compaction.• Thickness of compacted layer.

10

The EE/DyEE (V&QC) is expected to carry out actual field tests for all the above items for samples fairly representative of overall quality of the item.

TEST FREQUENCYGradation Test for GSB and Shoulder material.

In stage-I, minimum 1 test for every half KM (irrespective of the executed quantity).

Test for Liquid Limit and Plasticity Index

In stage-I, minimum 1 test for every half KM (irrespective of the executed quantity).

Degree of Compaction

In stage-II, minimum 1 test for every half KM length or part thereof (irrespective of the executed quantity).

Thickness of compacted layer

In stage-II, minimum 1 test for every half KM length or part thereof (irrespective of the executed quantity).

Grading for GSB: Material – If suitable GSB material has been used, ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded. Compaction and Thickness of Layer – If degree of compaction is within the prescribed limits and thickness of the layer is as provided in DPR/estimate, ‘S’ grade would be awarded, otherwise ‘U’ grade would be awarded.

VII) Base Course: In rural roads, generally base course of Water Bound Macadam(WBM) or Wet Mix Macadam(WMM) is being constructed. In WBM/WMM layer, the following items are critical to quality:• Gradation of course aggregates.• Gradation of fine aggregates (filler material and binding material).• Quantity of fine aggregates.• Adequacy of compaction.• Surface evenness.• Thickness of compacted layer. To ensure the conformance of course or fine aggregate to gradation requirements, EE/DyEE (V&QC) is expected to carry out sieve analysis.

11

In case crushable aggregate has been used as filler material, the plasticity characteristics are critical; therefore, EE/DyEE (V&QC) is expected to test PI and LL. There is prescribed method under the specifications for spreading the course aggregate, dry rolling followed by application of fine aggregates and to be continued with dry rolling. This operation is further followed by wet rolling. However, it has been observed that in many cases course aggregates and fine aggregates are haphazardly mixed and spread without any control over the quantity of fine aggregates etc and rolled unsystematically. There is an urgent need to check this practice of substandard construction of WBM. While the work of WBM is ongoing, the EE/DyEE (V&QC) is expected to check the process of construction meticulously and report. In case WBM has been completed, it is still possible to fairly judge the levels of compaction. To ascertain that prescribed dry rolling and wet rolling has been carried out for achieving appropriate compaction, it is necessary to carry out volumetric analysis by excavating pit of specific size. The material in each layer of WBM is required to be carefully taken out of the pit and after necessary screening to separate out course and fine aggregates, the proportion of fine aggregates by volume of course aggregates should be calculated. If proper dry rolling and wet rolling is done, the WBM would appear solid compacted and the percentage of fine aggregates would generally not be more than 25% of volume of course aggregates. Appropriate allowance for crushing under the wheels of the roller may also be made depending on the aggregate impact value of the course aggregates. If volume of fine aggregate is more, it is obvious that specified rolling has not been carried out. To confirm the levels of compaction, the pit should be re-filled with only the course aggregates and it should be seen that sufficient loose course aggregate should still remain balance after filling up the pit. In case of WMM, the procedures adopted at para 406 of section 400 of MORD specifications shall apply.The most important factor is that during mixing, the water in the wet mix should not vary from the Optimum value after taking into consideration the evaporation losses at the time of compaction.The speed of the roller should not exceed 5 KM/hour. Rolling shall be continued till the density achieved is at least 100 percent of the maximum dry density for the

12

material as determined by the method outlined in IS:2720(Part 7). After completion, the surface of any finished layer shall be well-closed, free from movement under compaction equipment or any compaction planes, ridges, cracks and loose material.

Frequency: The EE/DyEE(V&QC) shall record observations as given below:

Test FrequencyGradation Test for each layer of WBM/WMM

In Stage-II or III, minimum (1) test for every half KM for gradation of course aggregate and fine aggregate separately (irrespective of the executed quantity).

Test for Liquid Limit and Plasticity Index in case fine aggregates are crushable type.(WBM/WMM)

In Stage-II or III, minimum (1) test for every half KM (irrespective of the executed quantity).

Aggregate Impact Value of course aggregate material.(WBM/WMM)

In Stage-II , minimum (1) test for every half KM (irrespective of the executed quantity)

Volumetric Analysis for assessment of compaction of (WBM/WMM)

In Stage- III, minimum (1) test per every half KM. (irrespective of the executed quantity)

Surface Evenness usingStraight edge (WBM/WMM)

In Stage-III , minimum (2) tests per every half KM. (irrespective of the executed quantity)

Thickness of compactedlayer

In Stage-III, minimum 1 test per every half KM. (Average of left, right and centre for each test)

Grading for WBM: Material – If material of course aggregate and fine aggregate confirms to grading requirements and in case of use of crushable aggregate, it confirms to plasticity requirements, ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded.

13

Compaction, Surface evenness and Thickness of Layer – If by volumetric analysis, the proportion of fine aggregates to course aggregates is within the prescribed limits, the compaction of WBM/WMM layer is proper, thickness of the layer is as provided in DPR/estimate and surface evenness is within the prescribed limits, ‘S’ grade would be awarded otherwise ‘U’ grade would be awarded. If during construction the process of construction of WBM with appropriate dry-rolling and wet-rolling is not being properly observed, the quality would be graded ‘U’ irrespective of any other observations or grading for this item.

VIII). Bituminous Construction: Generally under BT, the work of 20 mm pre-mix carpet followed by pre-mix/liquid seal coat is taken up over primed and tack coated WBM base-course. In some cases, construction of bituminous macadam or modified penetration macadam is also taken up. Mix-seal surfacing is also being constructed in some parts of the country. The requirements of quality monitoring for various components of the bituminous construction are given below:

(a) Preparation of Surface for Bituminous Construction: It is extremely important to properly brush off loose material and fine aggregates generally available on the surface of WBM/WMM, however, it has been observed that cleaning of WBM/WMM surfaces does not receive proper attention of the staff of PIU/PRI/PR. The PIU/PRI/PR. is expected to check this aspect meticulously. Even in cases where the bituminous construction has been completed, it is possible to fairly assess this aspect by carefully removing the bituminous layer and observing the availability of loose material between the WBM/WMM layer and bituminous layer.

(b) Priming Coat and Tack Coat: Application of priming coat over the non-bituminous base-course by slow setting emulsion is prescribed in the Specifications. Application of tack coat by rapid setting emulsion or even by viscosity grade straight-run bitumen is also prescribed. Application of adequate quantities of bituminous material is to be ensured for both of these items and can be checked by conducting simple tests of the rate of spread. In addition, a uniform unbroken spread of emulsion/straight-run bitumen has to be ensured for both the above items and can only be ensured through its application by

14

mechanical spraying rather than spray by a perforated cane. Quality of emulsion with respect to proportion of water and bituminous material is critical in application of prime coat. The temperature at the time of application of straight-run bitumen is critical to the quality of tack coat. The PIU/PRI/PR staff is expected to make clear observations about these aspects. The EE/Dy.EE VQC shall conduct random inspections and make their observations on these aspects.

Frequency: If the work of prime coat and tack coat is ongoing the EE/Dy.EE(V&QC) shall carry out one test for rate of spread of binder. If the work in bituminous surface has been completed, the EE/Dy.EE(V&QC) shall carry out assessment of level of cleaning by removing bituminous layer at least at one spot in every 500 meters of the road.Grading: If the inspection is carried out during the execution of the above items, the quality grading of ‘S’ would be given if surface of base course has been properly cleaned and priming coat or tack coat using prescribed emulsion/ viscosity grade bitumen in prescribed quality and quantity has been laid. Otherwise ‘U’ grade would be given., In case, when the work is complete and upon removal of the bituminous layer if loose material is observed between the WBM layer and bituminous layer, ‘U’ grade would be given.

(c) 20 mm Thick Pre-mix Carpet/BM/MSS and Seal Coat: The following are critical to quality of bituminous layers:• Gradation of aggregate• Quantity of Binder• Mixing and laying temperature• Compacted thickness• Surface EvennessThe above aspects can be easily monitored when the work in this item is ongoing. While the work is ongoing, the assessment of quantity of binder may be made easily. The PIU/PRI/PR staff is expected to make clear observations about these aspects. However, when the work is complete, the EE/Dy/EE(V&QC) shall carry out bitumen extraction test and while interpreting the results, possible presence of binder used for tack coat should be appropriately accounted for.

Test Frequency

IX). Shoulders: For shoulders, appropriate material, as provided in the DPR, is to be used and construction of the shoulder has to take place simultaneously with construction of other layers of pavements. For monitoring the quality of shoulders the following quality parameters are critical:• Quality of material.• Compaction.• Thickness of compacted layer.• Simultaneous construction and compaction of shoulder with other layers of pavement. The EE/Dy.EE(V&QC) is expected to carry out actual field tests for all the above items for samples fairly representative of overall quality of the item.

Test FrequencyQuality of Material In Stage-I,II and III minimum 1 test for

X) Cross Drainage Works: There are a variety of CD works, taken up under various roads. Quality monitoring requirements for some common types of CD works are given below:

(a) Hume Pipe Culverts and Vented Cause-way: The following aspects are critical for quality of hume pipe culverts:• Adequacy of provision for face/main walls, wings and return walls has been made as per site conditions (whether these walls provided with appropriate design in appropriate length etc).• Quality of material and workmanship of face/main walls, wing and return walls.• Quality of hume-pipes• Adequacy of cushion over hume-pipes.• In case of vented cause-ways, quality and workmanship of surfacing over vented cause-way (generally, CC Pavement is constructed and quality monitoring as covered under CC Pavement would apply to this item also).

17

While the work is ongoing the EE/Dy.EE(V&QC) shall check all the above aspects and report. In case of completed hume-pipe culverts also the above aspects can be checked and reported. In case of cause-ways, it is important to check, as to whether; main walls have been appropriately keyed on the banks of the drain taking them well beyond HFL to avoid out-flanking in high floods. The EE/Dy.EE(V&QC) shall make observations on all the above aspects during his inspection and report.

(b) Simply Supported Slab Culvert or Cement Concrete Box Culverts: Quality monitoring aspects for such works would be decided on case-to-case basis.

Grading: If quality of material and workmanship is as per provisions grade ‘S’ would be given. Otherwise ‘U’ would be given.

XI) Side Drains and Catch Water Drains: For ensuring appropriate surface drainage, provision of side drains and if required, catch water drains followed by integration of these drains to across drain is critical. In case of hill roads, provision of side drains along with catch-pits of appropriate size at appropriate locations followed by provision of appropriate cross drainage work is critical. The EE/Dy.EE(V&QC) at all stages of inspection is expected to make clear observations about the aspects given above. He should clearly mention the adequacy of the size of the side drain and shall observe clearly, whether, the longitudinal gradient of the side drains is adequate for ensuring disposal of water.

Grading: If quality of material and workmanship is as per provisions grade‘S’ would be given. Otherwise ‘U’ would be given.

XII) Cement Concrete/ Semi Rigid Pavement and Associated Pucca Side Drains: In case of cement concrete and other semi rigid pavements, the following are critical to quality:• Quality of cement concrete. • Workmanship of cement concrete• Joints• Thickness

18

• Size and Shape of associated pucca side drains and their adequacy• Quality and Workmanship of material used in pucca side drains• Longitudinal levels of pucca side drains, their integration to cross drains or appropriateness of the provisions for disposal.• Cross drainage works While the work is ongoing, the EE/Dy.EE(V&QC) is expected to verify all the above items, however, while the work is complete, measurements about the thickness of CC Pavement, Surface conditions such as cracking etc may visually be seen, the register of cube test may be verified and based on visual observations, comments on quality of material and workmanship may be made. The aspects of size and shape of associated pucca side drains and their adequacy, Quality and Workmanship of material used in pucca side drains and Longitudinal levels of pucca side drains, their integration to cross drains or appropriateness of the provisions for disposal may be observed and recorded even if the work is complete. The EE/Dy.EE (V&QC) shall make observations about the above aspects during his inspection and report.

Grading: If quality of material and workmanship is as per provisions grade ‘S’ would be given. Otherwise ‘U’ would be given.

XIII) Road Furniture and Markings: Some funding agencies insist that every work is to be provided with Citizen Information Board and main board even before the actual grounding of the work. Logo boards and other road furniture are to be provided at appropriate time. The EE/Dy.EE(V&QC) shall check, as to whether, all Informatory Boards, as prescribed under the programme have been provided on the site and report. The EE/Dy.EE(V&QC) shall also check and report the quality of material and workmanship of road furniture and markings.

6) Observations on action regarding issues mentioned in earlier inspection reports of EE/DyEE(V&QC) or Third party Quality Monitors :

If the work being inspected by the EE/DyEE(V&QC) was earlier inspected by other EE/DyEE(V&QC)/others, the EE/DyEE(V&QC) shall make item and sub-item wise observations on the action by the PIU/PRI/PR regarding issues mentioned in reports of earlier inspections by EE/DyEE(V&QC) (or) any third party Quality Monitor and record these observations in the relevant item of work. In case, the EE/DyEE(V&QC) is verifying the Action Taken Report of PIU/PRI/PR on the observations of other EE/Dy.EE(V&QC) (or) any third party Quality Monitor, the EE/Dy.EE (V&QC) shall make his observations about verification in the separate sheet.

7) Sub-item/Item wise Grading and Overall Grading of Work: The sub-item wise grading of every item of work would be entered in the table at para 16 of Reporting Format 1 Part II and the item grading would be the lowest of the grading of sub-items within that item. The overall Item Grading would be calculated in the following manner.If, any of the items in item no. 5, 6, 7 and 8 are graded as ‘U’, overall grading of the work shall be ‘U’ i.e. ‘Unsatisfactory’.If, all the items given in above four items are ‘S’ but grading in any of other items is ‘U’ or ‘RI’, the overall grading of work shall be ‘S-RI’ i.e. Satisfactory but Requiring Improvement.If grading of all items is ‘S’, the overall grading of work shall be ‘S’ i.e. ‘Satisfactory’.Item No. Sub Item for Observation Awardable GradesItem No 1 Setting Out and Working Drawing (S –SRI--U)Item No 2 Site Clearance and Grubbing (S—SRI--U)Item No 3 Quality Arrangements (S—SRI--U)Item No 4 Geometrics (S—U)Item No 5 A Earth Work and Sub-grade in Embankment/ Cutting (S--U)Item No 5 B Earth Work in Cutting in Hilly/ Rolling Terrain (S--U)Item No 6 Sub-Base (S--U)Item No 7 Base Course – Water Bound Macadam (S—U)Item No 8 Bituminous Layer – Premix Carpet (PMC)/ Surface Dressing( S—U)

8) Submission of Hardcopy of Reports by EE/DyEE(V&QC): The EE/DyEE (V&QC) is expected to fill up the majority of observations in the prescribed formats during the inspection itself, however, in some items, in which the test results may take some time, the observations may be filled up latest by the next day. Immediately upon completion of the inspection but in all cases before the EE/DyEE(V&QC) leaves the district where he/she has performed inspection, he/she shall deliver the inspection report to the concerned PIU/PRI/PR and send a copy to CE V&QC.

9) Action on EE/DyEE(V&QC) Observations and Grade Improvement: Upon receipt of the inspection reports and observations of EE/DyEE(V&QC), the PIU/PRI/PR shall initiate action (if required) for rectification of defects (if any) pointed out in the observations. This shall be ensured by the PIU/PRI/PR that an Action Taken Report (ATR) on the unsatisfactory ‘U’ grade awarded, is furnished to the CE V&QC within 30 days of inspection. The CE V&QC shall scrutinize the ATRs with reference to the observations of EE/DyEE (V&QC) in the inspection report. The CE V&QC shall make his observations on the ATRs and communicate them to PIU/PRI/PR for necessary action. The process of verification of Action Taken Reports in the second tier would be carried out in the following manner:

(a) Every work is to be inspected minimum of 4 stages ( depending upon No. of items) during its execution, therefore, if there are any adverse observations ‘unsatisfactory’ about quality, the PIU/PRI/PR is required to rectify and report to SE concerned. The SE should satisfy himself about rectification of work, before forwarding to CE V&QC, however, the physical verification of the action taken should be done by EE/DyEE(VQC) or CE V&QC in their next inspection.

21

(b) Quality grading of work in the last inspection of EE/DyEE(V&QC) would be considered and effect of earlier quality grading would not be taken into account subject to condition that if in earlier inspections, the work has been graded as ‘SRI’ and the action for rectification is taken by the PIU/PRI/PR followed by verification of action taken report by the EE/DyEE(V&QC).

(c) If work is observed ‘Unsatisfactory’ upon completion, the work would be treated as non-rectifiable and difficult to re-grade the work as ‘Satisfactory’, unless detailed justification by SE concerned is furnished supported by test reports and reasons for such defective work, would not be able to accept the work and the PIU/PRI/PR would be required to carry out rectification and get the work re-inspected. In view of the above, the improvement in quality grades awarded under second tier of quality mechanism would not be required.10) Monetary Limit and No. of inspections by EE/Dy.EE V&QC:

In partial fulfilment of the instructions laid down in the Circular Memos No. QC9/DEE3/V&QC/Circulars/08, Dt. 25/04/2008 & 20/01/2009,

A) The EE V&QC has to follow the procedure as under :

i) Invariably at least one time inspection of the works costing Rs. 50.00 Lakhs and above.

ii) Random verification of the inspection reports given by the Dy.EE, V&QC as and when necessary, for works costing Rs. 50.00 Lakhs and above excepting BT Layer(which should be inspected by the EE VQC only) for which the inspection report given by the Dy.EE, V&QC previously and to report as per his observations and to follow the Government circular regarding the variation between two inspection reports

iii) Mandatory Inspection of BT surface work costing Rs.50.00 Lakhs and above.

22

B) The DyEE (V&QC) has to inspect & finalise all the works costing Rs. 50.00 Lakhs and above, compulsorily in four stages (except BT work),if CC/semi-rigid road work are also included in the estimate. 11) Selection and Performance Evaluation of EE/DyEE(V&QC): It is important to structure second tier quality monitoring in such a way that actual field realities are brought out, however, it is more important to ensure that the monitoring of EE/DyEE(V&QC) is correct and they carry out inspections properly and report truthfully. Therefore, it has been decided to evaluate the performance of EE/DyEE(V&QC) by adopting a scoring mechanism half yearly. About 5-10% of the inspection reports (or) 10 Inspection Reports whichever is higher will be evaluated by the evaluation committee members who may be the retired Engineer-in-Chiefs/Chief Engineers or Professors/Deputies of Osmania, JNTU, NIT Warangal etc., or both. The procedure regarding evaluation of EE/Dy.EE VQC is enclosed at Annexure

12) Tolerance limits/Rejections: The Engineer-in-Chief, PR Hyderabad (Sri D. Bhaskara Rao) vide U.O Note No.C.IV(1)/4084/2000 Dated 03/10/2000, has issued certain instructions to follow the guidelines in respect of Limits, Tolerances and Rejections as under:

a) Govt. Memo. No. 42243/Estt.1(1)/99-2 Dt. 9.2.2000 of PR & RD Dept.b) Cir. Memo. No. 7440/TEC/TA.15/AE.4/96-97 Dt. 24/01/2000 of ENC

R&Bc) Cir. Memo. No. 711/QC/D2/99, Dt. 15/04/99 of ENC R&B.

Further, the Govt. vide Memo No:15320/Vig-1/2005-1 dt:12/05/2006 of Panchayati Raj and Rural Development (VIG.1) department, issued guidelines/recommendations on rejections/tolerance limits stating that volumetric evaluation is inevitable in view of the huge number of works taken up at different levels and different magnitudes (Gram Panchayats, Mandals, Zillaparishads, Marketing, M.P Lads, Constituency development funds,) besides grants under FFWP,EAS, Employment generative schemes, Implementation of Government and Government of India schemes etc., The guidelines/recommendations issued in the reference cited will apply. The EE/DyEE(VQC) shall take action accordingly and propose recoveries/rejections as per procedure.

23

13) Responsibility for Lapses :

As per para -3(B)(d) of Memo No:15320/Vig-1/2005-1 dt:12/05/2006, the Panchayati Raj and Rural Development (VIG.1) department, the EE/DyEE/AEE/AE(VQC) are to be held responsible, if the average deficiencies pointed by them as per the quality control checks conducted are 50% higher than the deficiencies pointed out by other inspecting agencies like Vigilance and Enforcement department etc., in the works which were already inspected and passed by EE/Dy.EE(V&QC). The recommendations in respect of responsibility for lapses given in the above reference will apply.

ANNEXURE--2

Guidelines for Performance Evaluation of the EE/Dy.EE VQC

73

1. Background: Ensuring that the quality of the road works is the responsibility of the State Government, who is implementing the Programme, a two-tier Quality Control mechanism is stipulated. At the Second tier of the Quality Control structure, periodic inspections of works should be carried out by EEs/ Dy. EEs, V&QC. These officers are expected to carry out regular inspections and also get samples of material used tested in laboratories of the State Government as well as, in certain cases, independent laboratories, say established/ renowned engineering colleges or any laboratories notified by the State Government.

The main function of the 2nd tier of independent quality management is to improve the quality and effectiveness of the enforcement process. This includes

i) Checks to ensure that the 1st tier is properly functional

(ii) Independent quality tests to verify that the quality control system is achieving its intended objective

(iii) Detection of systemic flaws in the quality control process and action to improve the process

(iv) Independent supervision of deterrent and punitive measures in respect of the 1st tier and the Contractor.

Further, in order to be able to take an independent, impartial and dispassionate view of quality control, it is essential that the 2nd tier should have no stake in the outcome. In other words it should have nothing to do with the day-to–day or supervisory management or administration of contracts so that issues of legal action against the contractor, disciplinary proceeding against PIU officials, accountability to audit etc. do not colour its judgment or actions. Under the second tier of quality mechanism, detailed guidelines for monitoring of quality of the road works have also been prescribed. The method of inspection of works, making observations and reporting has been standardized with a view to minimize subjectivity in reporting. As per the guidelines, the EE/DY EE V&QC also has to upload the abstracts of the quality grading for each item of work along with requisite number of digital photographs in web site.

74

2. Performance Review: As above, the Second tier of quality mechanism is an important aspect of the State Government projects/Schemes and the performance of EEs/ Dy. EEs V&QC is critical for the programme, therefore, the performance of EEs/ Dy.EEs V&QC needs to be evaluated by the State on regular basis. Assessment in respect of the following aspects is required to be covered during the performance evaluation:

a. Whether the EE/DY. EE V&QC has carried out inspection as per the guidelines prescribed under the 2nd tier;

b. Whether there is any lack of application of mind by EE/DY EE V&QC in recording observations;

c. Whether there is a tendency to avoid desirable technical observations;

d. Whether the EE/DY. EE V&QC has left inspection format incomplete without any reason;

e. Whether the EE/DY. EE V&QC has filled up formats mechanically without appropriate testing or observations in a professional manner.

f. Whether the EE/DY. EE V&QC has uploaded the quality grading abstracts and the requisite number of photographs in web site.

3. Independent Committee: The review of reports of EE/DY. EE V&QCs shall be carried out by an independent Performance Evaluation Committee constituted by the department. The Evaluation Committee may consist of the following:

a. One Professor/ Deputy from any University in A.P – Member

b. One Retired Engineer not below the level of CE – Member

c. CE V&QC - Convener

The performance evaluation of EE/DY EE V&QC shall be based on review of 5-10% of the inspection reports or number, say 10, whichever is more, for inspection conducted in last one year/ six months just preceding the month of review.

4. System for Performance Evaluation of the EE/Dy.EE VQC:

75

The evaluation of every item and sub-item of inspection shall be carried out and the observations of the performance evaluator shall be quantified in terms of marks. Item and sub-item wise maximum marks shall be as per enclosed marking format (Evaluation Sheet). The marks obtained shall be filled up by the evaluator in the prescribed column. Based on the provision of specific item or sub-item of work, total maximum marks will not remain same in all cases and will vary depending upon the stage of the road work at which EE/DY EE V&QC has visited. Therefore, instead of absolute totals, a percentage will be taken for the evaluation.

Marking Methodology for Performance Evaluation of EE/DY. EE V&QCs:

Marking shall be done in the following manner given below. For easy understanding, guidelines for Quality Monitoring under Second Tier of Quality Mechanism including formats are attached for ready reference.

4.1 Setting out and Working Drawing: The EE/DY. EE V&QC is required to make observations on the basis of establishment of bench mark and center line and availability of drawings. Maximum marks would be 4 as detailed in performance evaluation sheet.

4.2 Site Clearance and grubbing: The EE/DY. EE V&QC is required to make observations on the basis of site clearance and use of salvageable martial. Maximum marks would be 2 as detailed in performance evaluation sheet.

4.3 Observations on Quality Arrangements: The observations of EE/DY EE V&QC on establishment of field laboratory, availability of equipments and use of equipments may be evaluated. For these items 3 marks are prescribed. The observation regarding mandatory tests, QC Register may be evaluated for these items 2 marks are prescribed. The results are required to be compared with the test results by the PIU in QC Register. It should be seen whether the EE/DY.EE V&QC has made efforts to verify these results and 1 mark is prescribed for this item.

4.4 Observations on Geometrics: In case of ongoing/ completed works, the EE/DY EE V&QC is supposed to measure the width of road way and carriage way, super elevation and extra widening at curves at a defined chainage and is

76

required to offer the comments about the adequacy for which 6 marks are prescribed.

4.5 Observation on Quality of Items of Work: The EE/DY EE V&QC is required to make observations on the basis of detailed test in respect of all the items of construction. He is required to get test pits dug to facilitate observations. Sub-item wise marking will be done in the following manner:

(i) Earth work: Maximum marks 10. The marking will depend on the quality of observations made by EE/DY.EE V&QC in case of three sub-items detailed in performance evaluation sheet for item 5A or four sub-items for item 5B.

(ii) Sub-Base: Maximum marks 10. The marking will depend on the quality of observations made by EE/DY.EE V&QC in case of four sub-items detailed in performance evaluation sheet.

(iii) Base Course: Maximum marks 10. The marking will depend on the quality of observations made by EE/DY.EE V&QC in case of five sub-items detailed in performance evaluation sheet.

(iv) Bituminous Course: Maximum marks 10 for Bituminous Courses.. In case of on-going works, grading of aggregate, binder and temperatures are to be observed by EE/DY.EE V&QC. In case of completed work, the thickness and surface evenness is to be observed by EE/DY.EE V&QC.

(v) The marking will depend on the quality of observations made by EE/DY EE V&QC as detailed in performance evaluation sheet.

(vi) Shoulders: Maximum marks 5. The marking will depend on the quality of observations made by EE/DY.EE V&QC in case of three sub-items detailed in performance evaluation sheet.

(vii) Causeways/Bridges of all spans/CD Works: Maximum marks 21. The EE/DY EE V&QC has to see adequacy of CDs and its quality. The marking will depend on the quality of observations by EE/Dy.EE V&QC with respect to location, type and quality of CDs.

(viii) Side Drains and Catch Water Drains: Maximum marks 4. The EE/DY.EE V&QC has to see adequacy of drains and its quality. The marking will depend on the quality of observations made by EE/DY.EE V&QC.

77

(ix) CC Pavement and Drains: Maximum marks 10. The EE/DY.EE V&QC has to see the quality of CC pavement / semi-rigid pavements etc. and drains including their integration with CDs. The marking will depend on the quality of observations by EE/DY EE V&QC as detailed in performance evaluation sheet.

(x) Road Furniture and Markings: Maximum mark 4. The EE/DY EE V&QC has to see the fixing of furniture and the quality. The marking will depend on the quality of observations by EE/DY.EE V&QC.

4.6 Inspection of roads under Maintenance: The State may also depute EE/DY.EE V&QCs to access maintenance activities being carried out in the completed road works. The EE/DY.EE V&QC is expected to clearly point out the defects noticed in road during his inspection and shall also report the current Pavement Condition Index (PCI) of the road.

4.7 Special Conditions:

a. Marking in case of Contradictory Remarks: If EE/Dy.EE V&QC has made such a remark in any item which is contradictory to remarks made in earlier part of the report, zero mark will be awarded in the item or sub-item where this remark has been given. Zero mark will also be awarded for that item or sub- item for which the earlier observations have been later contradicted.

b. Marks for not recording any observations: If the EE/DY.EE V&QC has not recorded any observations without giving reasons, Zero mark shall be awarded in that particular item/sub-item.

c. Marks in case of Incorrect Grading: If observations made for any item does not commensurate to the grading awarded to that item, zero mark would be awarded to the corresponding item.

d. Marking in case of wrong Overall grading: If the calculation of overall grading in the hard copy of the EE/DY.EE V&QC report is not as per guidelines, it would be a fair indicator of the care and sincerity of EE/DY.EE V&QC. No marking would be done in such a case and word “wrong overall grading” would be written on evaluation sheet.

4.8 Performance Ratings and Summarization:

78

Performance rating of the EE/DY.EE V&QC would depend on the average of marks obtained in all the evaluated reports. The summary sheet shall be filled up by the evaluator on the basis of average of observations in all the evaluated reports.
