1 Tender Notice/ Minimum Eligibility Criteria. Clause no 4.1 on page 1of 62 of Main tender Document

Work Experience : The bidder should have satisfactorily completed ”in the last three previous financial years and the current financial year upto the date of opening of the tender, track bed survey of 5000 kms for addressing the issues of Ballast fouling and formation related issues, the speed of track bed survey must be above 80kmph”

Fugro suggests to reduce the ballast fouling related experience criteria to 3000km in last 5 calendar years. Fugro can provide experience proof for multichannel GPR survey for roads addressing formation related issues. Fugro is of opinion that there is very little difference between collecting multi-channel (3 or more channels) GPR data on a road or railway. The technical details of setting up the system are the critical elements not the location. The knowledge of how to make sure the antennas are configured correctly is the critical component. The collection on the roads is very similar in that the antennas are mounted underneath the vehicle travelling at 80 Kph, where you cannot easily stop and adjust something on a motorway so the mountings have to be suitable. Kindly confirm acceptance.

Not Agreed. Condition mentioned in Minimum Eligibility Criteria. Clause no 7.1 on page 2 of 62 of Tender Document shall be applicable.

ZETICA Sl. No. Tender reference Queries Remarks

1. Section 4.5 Page 10/67

As part of a consortium bid, we would request RDSO to allow for payment to Indian Consortium partners directly in Indian Rupees. As a foreign partner, we would not have any Indian Rupee account and therefore, we would humbly request RDSO to allow for all foreign currency payment to be made us our account and all Indian Rupee payment to be made to the account of the Indian consortium member. We therefore, request for minor modification in this clause.

Consortium are not allowed for this tender; however, the issue of foreign currency bidding is addressed in the Revised Tender Document.

2. Section 19.4 /67

There is a comment in which it is stated that the price can only be quoted in Indian Rupees. We would humbly request RDSO to allow for all foreign currency payment ($ or £ or є) to be made to foreign partner/Member of consortium and all Indian Rupee payment to be made to the account of the Indian consortium member. We therefore, requested for minor modification in this clause.

Addressed in the revised Tender Document.

Please confirm the average recording speed of the TRC during normal operation every month. Furthermore, how much recording is typically done each day and whether a schedule will be made available in advance of each recording month. This would help us plan for data collection. This is only a request for clarification.

Answered previously.

6. Section 5 (iii) Page 29/67 Section 7 (vi) Page 30/67

Please provide a schedule of reporting extents for the deep trackbed deliverables. Please confirm the acceptance criteria for the deliverables. Please confirm if data would be provided in one go or in a broken manner every month. We suggest not more than 200 km of data be provided in any one month for detailed analysis. We therefore, request for minor modification in this clause.


7. Section 6 Page 29/67

Please confirm that due to the likely range of fouling materials, a single calibration determined at the start of the project may not be sufficient for the survey as a whole. Please confirm that there would be interest in providing relevant calibration for different parts of the network, based on the actual needs of Indian Railways/RDSO. We therefore, request for minor modification in this clause.

A-1 System Hiring Cost. Currently period has been given as 14 months while this should be changed to 22 months (on line with clause 2.0- Time of work-SCC). We therefore, request for minor modification in this clause.

Addressed in the revised Tender Document. System hiring cost shall be paid only for the months when the system is working and shall not be paid for the months when the system is not working as described in the relevant paras of the tender document and system hiring cost shall also be not paid for the time required before the start of the GPR Survey work.

11. Form 6 Schedule of Rates E1-(4) Page 63 of 67

We recommend an achievable measure of repeatability of 85% and an achievable of reproducibility of 80%. It is not possible to achieve 95% and 90% respectively for GPR survey of track. The definitions of the EN code are acceptable but the requirements for achieving these are unpractical for GPR survey in the rail environment. Based on previous experience, we recommend 3 or more overlapping surveys of a minimum 5 km in extent carried out in similar environmental conditions and within a period of one month. We therefore, request for minor modification in this clause to read as: ‘’The accuracy of repeatability shall not be less than 85% and for reproducibility the accuracy shall not be less than 80%. Repeatability and reproducibility would be as defined in the EN codes but repeatability should be implemented according to the following procedure. Three or more overlapping

surveys of a minimum 5 km in extent should be carried out in similar environmental conditions and within a period of one month’’.

12. Form 6 Schedule of Rates E6-Payment of recurring activities Page 65 of 67

When the sample size is large, is normally distributed and does not include outliers (a so-called Gaussian distribution), the mean score usually provides a better measure of central tendency. However, when the sample size is small and included outliers (a non-gaussian distribution) the median is a better measure to describe the central tendency of a set of data. GPR-derived and sampling measures of fouling can be non-Gaussian having the potential for outliers. Sources of (Non-Gaussian) error that can cause outliers include:

• Heterogeneity over small scales- fouling levels in one crib ballast compared to another can vary by an order of magnitude. We have seen differences in BFI levels of +/- 10 between adjacent cribs.

• Co-location – some errors can be introduced when sampling cribs which do not exactly match the location of the GPR result.

• GPR errors – Anomalous conditions (changes of ballast material, fouling material type, subgrade material change, moisture level, vehicle bounce, EMI) can introduce some error to the outcome.

Each month RDSO expect to cover 3500 to 5000 kms of track and the data validation would be done by sampling at 10-15 locations. Any large outliers in a small population (10-15 samples) can strongly influence a mean value. A median value would be more appropriate as would a non-parametric measure of the coefficient of determination (R2). The median % error would be calculated based on the result of the calculation (GPR-sample)/sample) for each of the 10-15 sample locations. The non-parametric measure of the coefficient of determination (R2) would be calculated using the Theil-Sen estimator for fitting a line to sample points by choosing the median of the slopes of all lines through pairs of points. We therefore, request for minor modification in this clause to read as: “If the median % error in the GPR-derived fouling and clean ballast depth is <= 35% or if a non-parametric measure of the coefficient of determination (R2) >=70% then the remaining 50% of the payment shall be released. If the median % error in the GPR-derived fouling and clean ballast depth is < = 45% but >=35% or if a non-parametric measure of the coefficient of determination (R2) >=60% but <=70%, then only half the balance 50% payment to be done while forfeiting the remaining 25% payment for the work done in the corresponding month. If the median % error is >=45% or the non-parametric measure of the coefficient of determination (R2) < 60% then the whole month’s survey and analysis along with the submission of reports is to be repeated.


If the median % error is >=45% or the non-parametric measure of the coefficient of determination (R2) < 60% consecutively for more than 3 reporting months the calibration and validation shall be done again. If the median % error is >=45% or the non-parametric measure of the coefficient of determination (R2) < 60%, even after recalibration, the contract shall be terminated.”
