General Remarks General RemarksThe following QC lapses have been observed during the inspection of the work as follows:General1As per agreement Date of handing over site is 13.9.2010 and the date for completion is 12.3.2011. As on date of inspection the value of work done is 98.80 lakhs & the work is completed. The Executive Engineer is requested to verify the progress of work in accordance with mile stones both Physical and Financial specified in the agreement and take appropriate measures as per agreement conditions.2Some of the KM & HM stones are missing. The field officers have to fix up the same duly painting and numbering at correct chainage location.3As per clause 1.11 of IRC SP-11 Quality Control for construction of roads and runways. Out of total tests, preferably 70% to be carried out by AEE/AE, 20% by DEE & 10% by E.E. The test result record register shall be presented to the QC staff during there inspection. This is not followed.4The longitudinal undulations and camber are exceeding the specified tolerant limits specified by the MORTH.5As per para 2 (viii) of G.O.Ms.No: 84 of I&CAD (PWQC&IWS) Dept. dt: 8-8-2000, Check measurement is to be done by higher officers at 1/3rd, 2/3rd stage of work and should cover not less than 30% of the total expenditure incurred each time. As verified from the M-Books, it is noticed that this is not followed.6The Government vide G.O. Ms. No. 80 of T R&B (RI) Department, dated 25.04.2005 have issued certain guidelines on road safety along with certain road safety interventions to be taken up duly making provision in the estimate and to execute the same without omission, so as to avoid / minimize the road accidents but the field officers did not put forth any efforts to execute the road safety measures and its amounts to violation of government orders.4) BM & SDBC7The field officers have not conducted the tests as specified in MORTH to confirm the bitumen used on the work is 60/70 grade for for SDBC.8The density of SDBC observed is 2.102 grm/cc. The Field Engineers are requested to conduct the density tests of SDBC at closer interval and ensure the density of SDBC with specified density as per the job mix formula, and shall take appropriate measures as per agreement conditions.9As per agreement, laying of SDBC is with bituminous binder of with 60/70 grade from refinery at 5.00 % by total weight of mix. The field officers have not produced copy of bitumen bills during inspection. The Executive Engineer (R&B) is requested to insist upon the field officers to furnish the copy of bitumen bills noting name of work details duly counter signed to this office for verification.10Newly laid SDBC rough, not sealed properly at some places and is likely to get damaged prematurely due to infiltration of rain water. Segregation of chips observed on top surface at some places.. The field officers should be more careful during execution of works.11It is observed that the Longitudinal joints for BT surface are not made as specified at some locations. The Field Officers has to follow clause 501.7 of MoRTH specifications, while laying longitudinal joints.12It is observed in some of the sample pits that cleaning was not done properly before laying SDBC.13As per the observations of the Q.C wing and as per the QC tests conducted at our QC labs, on the SDBC sample extracted at the above mentioned locations the recovery amount works out to be as follows in respect of GSB, WMM, BM and SDBC items only.Recovery AbstractRecovery towards less bitumen content in SDBC67455.0014The Executive Engineer (R&B) is requested to effect the recovery of Rs 67 455 /- from the contractor bills towards less bitumen content in SDBC observed by the QC wing for the items of works inspected, tested and intimate the recovery particulars such as MB No. and CB voucher No along with the compliance report on all the lapses pointed out in the above General Remarks.NOTE: -1The Q.C report furnished above are not basis for making payment on the work as it does not purport to be covering all the aspects of the work and field Engineers are requested to check up the work at closer intervals during process control and also requested to conduct necessary QC tests on finished item of works and satisfy themselves before making payment. If any deficiency is observed other than shown in this QCR, the recovery shall be effected as per Engineer in Chief (R&B) (Admn & Roads) circular Memo No: 12582/Vig-I/1/2005-1, Dt: 17-10-2006.2The field officers are requested to check the recovery calculations as per agreement conditions before effecting the recovery, keeping in view Engineer in Chief (R&B) (Admn & Roads) circular Memo No: 12582/Vig-I/1/2005-1, Dt: 17-10-2006.3The Q.C report furnished above is not valid for any evidence in any court of law.4The test results given in the Q.C report are valid for the samples extracted at the above-specified locations as the same were tested in our Q.C laboratory only.5The recovery amount proposed in QCR does not include for the items of work which requires rectification as pointed out in General Remarks. The QCRs issued based on the observations made on the day of inspections and if any unraveling or damages occurs / took place subsequently should be watched carefully and prompt action shall be taken for rectification. After rectification only payment shall be made but not solely based on these QCRs.Assist.Exe..Engineer(R&B)Dy.Exe.Engineer(R&B)QC Sub Division, KadapaQC Sub Division, Kadapa
