their replies are enumerated below.
The Representative of Science consultant wanted clarification on the following points
Q Do we have to use the same roads as they appear on SOI Maps or they have to be modified?
A If some roads are picked up from map and some from high resolution image, the roads will not sit exactly on image therefore roads should be drawn afresh from satellite image. A road up to black top has to be extracted. SOI maps can be used for annotation.
Q Up to what level drainage and canal system has to be picked up.
A As Punjab State is mostly plane and maps hardly indicate any contours therefore drainage pattern and canal system will define the lie of the ground also SRTM/any other 30m height data will help us to know about the low lying area in the district.
Q In case of built up area what details shall be picked up
A In case of built up area only the localities are to be marked and any detail inside locality if found vulnerable shall be picked up. Buildings like a Shopping Mall or a multistory building will fall in this category. Also core area of the city which is congested shall be considered as vulnerable.
Q In case of Roads, how categorization of roads shall be done.
A Roads shall be categorized as National, State, District and others.
Q In the tender transmission lines have been indicated, up to what level transmission lines shall be picked up.
A Pylons are to be considered as vulnerable, Mostly transmission lines on pylons are shown on SOI maps. Also in many cases pylons are seen on satellite image also, the transmission lines on pylons are to be picked up. Substation from where power is distributed also becomes critical hence should be picked up.
Q In the tender, Name of land holder also has been indicated to be picked up.
A No name of land holder need not be picked up. Tender shall be modified accordingly.
Q Whether details are to extracted in 2D or 3D mode
A Details are to be extracted in 2D mode only.

A Irrigation authorities of Jallandhar and Drainage authorities can be requested to provide data
Q In case of schools and colleges the number of rooms has been indicated, you are requested to confirm

A Yes
Q Whether time required for preparation of Composite Risk Atlas will be one year.
A It will be 8 months.
Q In the payment clauses it is mentioned that whenever a payment is made a Bank Guarantee of the same amount is to be submitted. It is suggested if the bank guarantee of 50% of the payment amount is asked in place of full amount. Also it should be indicated that how much shall be maximum time taken for final payment once the data or deliverable is submitted.
A After discussions it was agreed
that bank Guarantee against payment as indicated in the tender will be 50%. Max
time taken for clearance of data shall be 3 months and hence final payment
shall be cleared with in 3 months.
Q On
what format data shall be prepared
A Data
shall be prepared on ARC Geodatabase.
Q Whether
History of Atlas shall be prepared or not
A Yes
History of Atlas shall be prepared. Topics like, how it was executed, what form
of data was collected and from where it was collected. Also any further
suggestion would be indicated.

What is the meaning of
the note on Page 19? "Note: Since Satellite images are the license
product therefore no copy of the same to be taken out by the firm on any account
out of the premises.” Our understanding is that "Premises"
means the office premises of the vendor. Please clarify. |
|
Premises
means the site given to Vendor at District HQ for working. The soft copy of
the satellite image he has to keep at that site only. |
||
|
|
“DEM also should
be prepared using SRTM data.” The resulting DEM prepared will be 90 m
in horizontal resolution. Please clarify. |
|
SRTM
90m grid or better resolution
data from other open source should be used for creating DEM |
||
|
|
Are Earthquake, Flood,
Drought, Fire and Chemical hazards the only hazards to be looked
into? Please clarify. |
|
In
Punjab Mostly these hazards have the history but other hazards canalso be
looked into |
||
|
|
"Highest flood
level and calculating area of submergence and showing as layer." The
"area of submergence" has to be generated only for the highest flood level. Please
clarify. i. What help will be
provided by the Client in obtaining the historical |
|
The
provision for calculation of submergence by giving the flood level is
possible in certain S/W. But in this case Highest flood can be the layer. Historical
data has to be collected from Flood and irrigation Department of the State.
This information shall be available with Revenue Department also |
||
|
|
"Irrigation
network and the depth and flow of canals and rivers flowing in the district". i. Where will the data
regarding depth and flow of canals be available? ii. For how many years
and at what granularity (like quarterly, monthly, weekly, and
daily) will the flow data be available? iii. Will the canal
depth information be provided through AutoCAD drawings as digital
data or on paper drawings? |
|
The
data regarding Rivers and canals can be from SOI map. The data of depth Etc
shall be available with irrigation Department. The
above data is being maintained mostly on paper drawings |
||
|
|
"Types of chemical
plants and their locations to be picked up." Is this information to be
collected through survey or is this data available and can be obtained from some
Agency? |
|
This
information should be available with Department of industries but if not then
it has to be collected by Survey |
||
|
|
"Population data
to be collected from latest census." Since the study is at village level,
population information would also be required at the village level. But Census data
does not provide population by villages. In that case, Is this information
available somewhere else? |
|
The
population data can be shown as available in Census can be in the form of
density. There are District planning maps available with SOI/NATMO, some help
can be taken from them also |
||
|
|
"Drainage and
canal system" Does this refer to open drains or underground sewage pipelines also? |
|
Paper
drawings of drainage system are mostly available with Sewage and drainage departments in the towns where
as in case of open area SOI maps can be referred to. Under ground Pipe lines need not be surveyed |
||
|
|
Our understanding is
that risk assessment has to be based on visible and collected information only
and no risk modeling is expected. Please clarify. |
|
Yes |
||
|
|
|
|
No |

|
|
We would like to get
further details on the Selection Criteria |
