General Technical Approach As per our understanding sensors to be installed at one station will be connected to data logger and data will be transmitted to data center through GPRS. Please confirm for which all stations, bidder has to combine data and which technology is to be used for the same. Please clarify
Normally, clubbing is done
with a spread spectrum
wireless link. You can think
of the wireless link just being
an extension of a wire to the
sensor, except there is no
wire, and instead the radios
is used to provide
connectivity over the
distance of 1km or so (line of
sight).This, or any wireless
link, must conform to laws
for wireless communication
in India. Each data point is
separate. Not that many

14 Under the sub section of 5.1 Real time Hydrologic Data Collection Network 5.1.2.2 ADCP River Discharge Measurement
The WRD Bihar requires two ADCPs (Acoustic Doppler Current Profiler). These ADCPs will be down looking system that shall be used for manual stream gauge measurement The ADCP will be provided with all accessories to make measurements from a bridge, boat, tag line and from a **cableway*. This includes a floating platform. This equipment will be used by the bidder and serviced by the bidder for repair due to malfunction or other equipment breakdown. This equipment will be used by the Purchaser during the maintenance transition period and stay in the possession of Purchaser at the end of the operation and maintenance contract Points of clarification: 1. How a bidder can supply the ADCP with Bridge?* 2.More ever if Cable way is used then it should be specified as Boat is now a day‟s not preferred due to safety reasons and Cable way is only solution if bridge is not available at the site.
i)The no. of ADCP (down looking) to be supplied will now be 3 nos. instead of 2 nos. stated earlier ii) Consequently no. of current meters to be supplied will be 3 nos. instead of 2 nos. ADCP will be provided with
all accessories to make
measurements from a
bridge, boat, tag line OR
from a **cableway*.
This is left to bidder to decide best approach.
15 5.8 Operation and Maintenance
The other requirements for maintenance will be as under.5. It is expected that the average downtime of an item will be less than half of the maximum downtime (ie defined as number of days for which an item of equipment is not usable because of inability of the Bidder to repair it). The maximum downtime for any item is taken as 90 days. In case an item is not usable beyond the stipulated maximum downtime the Bidder will be required to replace equipment *and infrastructure such as cableways and instrument shelters The Cable way is permanent structure which works to carry the equipments with shelters and only traveller box may need repairing / replacement of the system.*
In all probabilities the bidder has to ensure that the whole system is in working condition beyond the stipulated maximum downtime by suitable replacement of accessories or its parts as mentioned in bid document
16 Bidder assumes that for the Water Level Gauging sites does not need Rain fall Sensor. The Rainfall gauging is exclusively from 20 Stations
Yes. Both rainfall and river gauge sites are different.
17 Consortium may be granted to bidder instead of JV
The bidder may submit bid as a single entity or as a joint venture.
18 We have seen the technical specifications of the above referenced tender and have the following observations: 1. Side Looking ADCP
a. Velocity resolution 0.2cm/s maximum;
resolution could be higher so it should be either deleted or word minimum should be substituted b. Channel width not specified; you have said it should be inspected but given that only one number is required, maximum channel width available should be given. Bidders may choose or fail to give the correct type of ADCP.
The specification stands as deleted
Badlaghat site is changed to RADAR Level type. Refer Sl. No 2
19 2. ADCP River Discharge Measurement a. The type of floating platform has not
been specified. It is suggested that a Trimran be specified as this would provide stability in high flow conditions.
b. Profiling distance is given as 0.3 –10m and depth range is given as 0.3 – 30m; if the depth range is 30m it would be best to profile the water column to 30m. Please clarify.
c. The specifications call for computation – all performed internally. We do not see any reason or advantage for this function; infact it can be a disadvantage.
First, a computer (e.g., a note book PC) must be used in the field to operate an ADCP. The computer runs the ADCP operation software that will set up an ADCP, collect and display the data for velocity, depth, track, etc. The software will also calculate discharge using the data collected. The data collection and display, and the discharge calculation are done by the
Yes, The Bidder
should use maximum
high water point.
As already stated in Sl.No. 6
computer in real-time so that the operator can monitor the discharge measurement. This has been and still is the standard operation and quality assurance procedure for ADCP discharge measurement used by many hydrology survey authorities all around the world.
Second, if no data come in and display on the software/computer during a transect of discharge measurement, there might be one of the two causes: (1) the communication between the ADCP and the computer drops, or (2) the ADCP somehow stops working. In this event, the operator may have to stop the transect, check the ADCP or communication, then redo the transect. It is not a good practice that the operator still continues the transect in the event and relies on the internal discharge calculation feature. This is because the operator cannot be sure the velocity/depth data will be collected and discharge will be calculated unless he/she sees the data and discharge calculation in real-time on the computer. In addition, redo a transect is not a big deal and the current international standard is to conduct at least four (4) transects at each site.
In summary, the internal discharge calculation feature has no practical value for ADCP discharge measurement. Its use, in fact, will add an uncertainty for data quality control and assurance.
TRDI ADCP have a 16 MB internal recorder that records all data all of the time, even in the event that the communication between the computer and the ADCP drops. These data can be displayed and discharge can be calculated in the post processing. That is, although our RiverRay ADCP does not calculate discharge internally, it records all of the original data that the discharge can be calculated from it
20 In the specifications for the precipitation gauge it is stated that the resolution for the rain gauge shall be 1mm. We have rain gauges that offer a better resolution of 0.2mm and 0.5mm. Please confirm if the rain gauges with resolution specification better than 1mm will be acceptable.
The specification is clear.
21 On page 107 of the tender document second para it is stated that:
The bidders estimate for warranty and maintenance shall consider that payment will be made on a quarterly basis. Maintenance will be performed as quickly as possible considering the technical staff limitations. Sensors not working for more than 24 hours shall incur a deduction of Rs 500 per day per station beyond the first 24 hours. Failed data communication in real-time shall incur a deduction of Rs 500 per day per station beyond the first 24 hours. A station failure shall incur a deduction of Rs 500 per day per station beyond the first 24 hours. Only one deduction will be made at a given station for a given day, limiting the maximum deduction to Rs 500 per day for each station. Deduction in payment towards sensor not working or station (failure of sensor and datalogger together for any reason) is acceptable. But deduction the failure of data communication in realtime through GSM/GPRS link seems unreasonable. This is because availability of the GSM/GPRS link not totally in bidders control. There will be issues with network service provider (such as Airtel or BSNL) in the remote areas where voice traffic could be their priority and data may not be. While we can make all attempts to restore the communication link in follow-up with the service provider, deductions in payment due to non-availability of the realtime link seem unreasonable. We therefore request to please consider removing the penalty clause on account of “failed data communication in real-time” or at least give it a grace period of 7 days instead of 24 Hrs.
It is absolutely
unacceptable to allow for
missing data, especially
during exceptional events
(floods).
22 Rating Curve for the river gauging sites:
In the tender document it is stated that the bidders are to develop and update the rating curve for the duration of the contract (warrantee and post warrantee AMC period). Developing the rating curve for the sites will require the historic data input to come-up with the preliminary rating that can be further fine tuned with time as the water level variation and the corresponding discharge values are captured by the proposed system (river gauge and ADCP). We hope that the client understands the developing and updating of the rating curve will be an ongoing thing exercise at least for the first full year to arrive at a stable reading.
It is extremely important that over the first year that as many measurements as possible are made during rising and falling river levels. An initial rating curve can be developed over the course of one significant river rise.
23 Please provide the max and minimum width of the cross-section (monsoon and non-monsoon) and the max and minimum water level (monsoon and non-monsoon) at the site where side looking Doppler instrument is to be installed for monitoring of flow/discharge in the project
As stated in Sl.No.2
Station is changed to
Radar Level type.
The width of rivers
during peak flow and
dry season at the sites is
however given in the
Table 1.1
24 In the Bidders Evaluation Criteria it is mentioned that :
The bidder should be a manufacturer who must have manufactured, tested and supplied the equipment (s) similar to the offered type specified in the „schedule of requirements‟ up to at least 50 sensors coupled with a datalogger in any one of the last 3 years. The equipment offered should strictly conform to or exceed the product specification and be in satisfactory operation for 6 months as on date of bid opening. Further, bidder should be in continuous business of manufacturing products similar to that specified in the schedule of requirements during the last three years prior to bid opening. Similarly if the bidder is bidding on behalf of the manufacturer one of the criteria is: (ii) The bidder, as authorized representative, of the manufacturer, has supplied, installed and
Provided at least one of each sensor be included in this criteria.
commissioned satisfactorily at least 15 of the quantity similar to the type specified in the Schedule of Requirements in any one of the last three years which must be in satisfactory operation for at least 6 months on the date of bid opening. The bidder must provide evidence of providing maintenance services for the above type of sensors coupled with data logger installations in at least ONE centre in the Country for over one year. In case the bidder is unable to provide evidence for maintaining such systems the bidder should provide a plan for provision of after sales service and annual comprehensive maintenance for the next five years along with the evidence of maintaining instruments using similar technology (a sensor coupled with the data logger) with similar coverage and amounting to at least 70% of the total cost of the offered bid in any one of the last three years. Since the current project requires four different types of sensors viz. bubbler type water level monitoring sensor, rain gauges and side looking Doppler instrument and down looking Doppler profilers – we understand that the quantity requirement of 50 numbers for sensors in case of manufacturer and 15 number of sensors in case of bidders bidding with a manufacture’s authorization from qualified manufacturer can be any combination of these sensors as long as they meet the 50 or 15 sensors criteria. Please confirm.
25 We propose that INSAT systems
should be used because in disaster the
first things to be affected are
GSM/GPRS network, so we propose
use of INSAT.
At present FMISC is
planning for GSM/GPRS
network and in future may
go for satellite based
communication system.
26 Do all the sites have GPRS
connectivity?
GSM/GPRS coverage is
available.

GoB will provide rating table (based on historical data) for discharge calculations at bubbler sites till a complete rating table generation by ADCP is completed.
Kindly confirm.

Both, Data polling by server and
Data Reception by server, are
mentioned in tender document. In
GPRS mode data polling from
GRS is not possible as SIM with
static IP is not provided by cellular
service provider. Polling can be
done by using Circuit Switch Data
(Dial Up) connection which will
not be GPRS and CSD connection
happens one by one and not
simultaneously.
Kindly confirm whether GRS will
receive or poll the data.
GRS will generally receive data but some mechanism has to be worked out to poll the stations when data transmission is erratic or missing
57 Line 14 Page 103 Internet connection
It is mentioned that primary internet connection to use will be
It will be provided by FMISC
provided by GoB. The internet
connection at GRS should have
static IP as it is required by
remote station SIM to sent data
to.
Kindly confirm.
58 Line 31 Page 103 Times Series Software
The tender document mentions 3
time series software. Can we
provide software of other brand
other than mentioned in tender
documents ? Kindly confirm.
It can be from other brand also as long as functionality remains the same
59 UPS Page 104 In Bill of quantity only 1 UPS is
mentioned, for the 3 servers, which
will provide 60 minutes back up. It
is our view that it is better to have
separate UPS for each server so
that fault in one UPS does not shut
down the whole system
FMISC shall have alternate UPS connectivity also.
60 Telemetry Category II Page 112
In the table, Telemetry is not mentioned. We assume that it is GPRS.
Kindly confirm.
yes
61 Precipitation GaugeAir Temperaturer (Page no. 83)
Bucket Capacity: 1mm Can we offer with 0.2mm which has better resolution? Please confirm.
The specification is clear.
62 Bubbler System (Page no. 84)
i. Continuous bubbler (line under pressure
continuously) utilizing supply tank OTT Bubbler works on advanced static method in which the measuring (Orifice) tube is directly connected with piston pump to release bubble in to the water as per water level. In this way, it minimises the maintenance, power consumption, moisture etc. as the unit produces bubbles only when a measurement is initiated. Thus OTT Bubbler does not require air tank. OTT Bubbler is USGS HIF certified. CWC is already using more than 150 nos. Of OTT Bubbler Sensor. Hence, request you to allow us to offer OTT Bubbler which is not only meets
i)The Bidder should meet the technical specification requirement. ii) Please also note that only 2 nos of “Bubbler Type” are now to be installed at Sonakhan and Karachin sites where there are no bridges. iii) At the remaining 5 sites where there are bridges viz. Dhengbridge, Dubadhar, Chandauli and Goabari “Bubbler Type” is now replaced
your requirement but also offer better features like energy saving & maintenance free technology. Please confirm.
ii. Bubble rate adjustable from 30 – 120 bubbles per minute
By means of an intelligent pump strategy, the pumping time in the OTT CBS, or the number of pump strokes, is dynamically adjusted to the changes in level. This makes OTT Bubbler more accurate and you do do not have to set bubbler rate as it is not required. It
saves your visit to site to change bubble rate. Allow us to offer OTT Bubbler with better measurement technology for better accuracy? Please confirm.
iii. Manual purge with supply tank OTT Bubbler has manual purge without supply tank that makes it low maintenance sensor. Please confirm. iv. Range of bubbler and pressure
transducer shall be 30 psi. In the case the range of water levels is greater than 20m, an orifice manifold system with 5m of orifice line overlap will be used to cover the entire range of water level with a single sensor. The manifold system need not be automated. OTT Bubbler sensor has 30m range, hence you will not need orifice manifold. Please confirm.
