15.  On the requirement of Integration of existing Radars, please confirm that PAGASA’s respective vendors will be responsible for the timely calibration of their respective existing radars and quality control of all the data from these existing radars. Un-calibrated radars will produce distorted and inaccurate results, thereby affecting the output/results when integrated.

(This Answer addresses Query Nos. 15-17 of this SBB)

The End-user Unit will closely coordinate with the respective vendors of the Agency’s existing radars for the timely calibration and quality control of the radar data as well as securing the needed Certificate of Calibration.

16.  Please confirm that PAGASA shall provide or secure from its respective suppliers the Certificate of Calibration before Integration.

17.  For purposes of Integration, please confirm that PAGASA shall be responsible of getting the data from these existing radars and then push/dump all the data to a certain server. Otherwise, PAGASA may also require all existing radar vendors to push/dump the raw data to an available server of PAGASA.

18.  Since communication cost to the cellular operator and internet service provider, and VSAT subscription will be scoped by PAGASA, please confirm that PAGASA shall be responsible for the data transmission and its failure in any event that transmission of data is down.

The requirement is self-explanatory.

19.  Please provide the list and numbers of radars to be integrated.

The list of the Agency’s existing radar systems is indicated under Annex “A”, of this SBB.

20.  What is PAGASA’s existing SCADA System?

PAGASA’s existing SCADA is capable of monitoring camera, DEG, airconditioning units, doors, power supply. This is a separate channel, in addition to Radar monitoring function, Radar products, BITE (Built-in Test Equipment), alerts, and others.

21.  For purposes of Integration, what will be the scope/responsibility of PAGASA and of the bidder when it comes to integration of the existing radars?

For integration aspect, bidder shall be responsible for the provision of a composite image of all existing PAGASA weather radar systems including the new six (6) sets of Radar Rain Gauges. (Please refer to Section G, No. 9.0, page 15 onwards).

PAGASA, on the other hand, shall be responsible for the timely calibration of existing radars, maintenance of a smooth communication system through monthly subscription of VSAT and leased line or LTE/3G.

33.  This is limiting the tender to specific Solid State Technology whilst there are several who can comply by not being specific to solid state. Can we generalize the same and include or amend “The Manufacturer should have 5 years’ experience in Weather Radar or X-Band Weather Radar” and not be specific to the Solid State Technology.

(This Answer addresses Query Nos. 33-41 of this SBB)

PAGASA maintains its requirement for X-Band Dual Polarization Radar Rain Gauge using a Solid State Technology.

It must be clarified that, while PAGASA’s choice of a solid state transmitter will somehow limit this tender to a specific technology, such requirement is not alluding to only one (1) type of brand as claimed by the prospective bidder.

PAGASA’s preference of this type of technology was already substantiated in the Terms of Reference (TOR) of the Project.

34.  Meaning the same X Band Weather Radar project or any Radar Weather project?

35.  X-Band Weather Radar using Solid State Technology is a fairly new technology. Our proposal is to open it to just the Weather X- Band technology and not be specific on the dual polarization Solid State X-Band Weather Radar which maybe alluding to one Japanese brand; if we are to consider the number of years it has been supplying it.

36.  Based on the 3 cited, we would like to ask why PAGASA decided to specify Dual Polarimetric Solid State X-Band Radar, where Solid State Radar have:

a.     A longer Duty Cycle which involves longer periods of current draw specifically for remote areas where there is perceived to have a significant amount of rainfall detection.

b.    The average Duty Cycle of the Solid State X Band is 0.05% or 5% with a Pulse length of 50Micro Sec and a PRF of 1000Hz whilst the Magnetron Based X Band Radar is 0.0004 or 0.04% with a shorter pulse length of 0.8Micro sec at a PRF of 500Hz. This then translates to an average reading of 5watts which is lower than the solid state X Band Radar at 6W or more. All radar engineers know that the average power is the most important as it is the actual operating power.

c.     Also, the power draw increases during extreme weather events which may overload and incapacitate that Radar considering, it’s remotely installed, which negates the objective of “lower power consumption”.

37.    Magnetron Based X-Band Radars have more precise rainfall measurements because the sensitivity is greater than the Solid State Type.

38.    Magnetron Based X Band Radars have higher sensitivity, like 5.4 dBZ @ 25Km (0.024 mm/h) 18.1 dBZ @ 108 Km (0.23 mm/h) or even higher; against a sensitivity of 1 mm/h at 80Km as written in the TOR.

39.    The difference in sensitivity is more than 75%!!! This negates the first objective of accurately and timely forecast.

40.  Longer Reach

If the present specs on sensitivity is required, some magnetron based X-Band Weather Radar can reach more than 200km.

41.  Lesser Maintenance cost in long term for magnetron versus SST

42.  Our proposal is to relax the provisions in the experience of the technical personnel. An ECE or an Engineer with a 1 year Communications background can actually address the maintenance requirements if that is the concern. This is considering that the base technology is Radars and Communications. Most of the components are replaceable component based systems. Notwithstanding the fact that the X-Band radar is just a subset of the technology. Considering the above, the maintenance requirements of our X-band Magnetron Radar will not take 1 hour to replace and keep it running again. Also, the early provisions is appraised to limit the qualification to only 1 bidder specifically citing the fact that the required experience is a minimum of 5 years in the installation and maintenance of Weather Radars.

PAGASA’s minimum requirement shall be maintained.

Normally, projects of this nature have a longer lead time in the maintenance, development, delivery and installation. It would take 12 to 36 months to supply and deliver this project from the time the NTP is released. During the initial stages, the actual installer will be coming from the Manufacturer stationed in a foreign country. The experience then to the local engineer is supplemented with the actual installation within the project cycle.

43.  Our proposal is during the commissioning, the supplier would provide the necessary Philippine staff which would install the same and provide the necessary after sales support. The same Engineers/Technicians must hold office in PAGASA during the warranty period to provide a focused maintenance support arrangement and lessen the downtime of the radar system if and when problems arise in the warranty period. This then addresses the requirement of availability of the engineering services majoring in communications.

This matter will be thoroughly discussed by the PMC with the winning bidder prior to the implementation of the Project and shall form part of the Contract.

44.  If we install the Hydrological software, do you have a “Oracle License for the databases? Or do we need to include the Oracle license in the proposal?

Section F (Scope of Works) of TOR only mentions Hydrological Products (Part 8.5). Please refer to minimum requirements mentioned in the TOR.

 

 

 

 

45.  It is not clear whether the Web server is a public one or PAGASA internal?

The web server for this project will be INTERNAL. PAGASA will determine the products that will be posted and will be made available in the public server.
