BACKGROUND:

On behalf of Defence Research Development Canada (DRDC), an Agency of DND, Public Works and Government Services Canada (PWGSC) is requesting proposals for the acquisition of goods and services to design, build, install and operate two communication sites in the Canadian High Arctic. One site will transmit data, the other will receive data. It is intended to issue one firm-priced contract per site and have both sites fully operational by April 2019. Each contract may extend the operational component by three one-year periods.

The contract work supports the All Domain Situational Awareness (ADSA) Science & Technology (S&T) Program of DRDC in its study of the feasibility of using sky-wave over-the-horizon radar technology in the polar cap region of the Canadian Arctic for detecting air targets, referred to as polar over-the-horizon radar. The requirement moves beyond sounding and involves putting together radar functional components at an Arctic Site. The goal is to determine the effect of the Aurora Borealis on target detection beyond line-of-sight.

Suppliers are to refer to the Request for Proposal (RFP) for full details on the requirement. Below is a summary of some key aspects.

VARIA

Bidders may apply for one or both locations through a separate and distinct bid for each Site.

Comprehensive Claims Land Agreement: The solicitation is subject to the Nunavut Land Claims Agreement (NLCA)

Canadian Content Policy: Proposals offering goods and services meeting the Canadian Content Policy may favoured.

Evaluation criteria and selection of proposals: Proposals must satisfy mandatory and point-rated criteria. Selection is based on the lowest priced proposals that satisfy the criteria and other requirements of the solicitation.

International Trade Agreements: The requirement predominantly falls under the Federal Supply Classification (FSC) code 58 and is therefore excluded from each of the North American Free Trade Agreement (NAFTA), the World Trade Organization - Agreement on Government Procurement (WTO-AGP) and the Canada-European Union Comprehensive Economic and Trade Agreement (CETA).

Domestic Trade Agreement: The requirement is subject to Canadian Free Trade Agreement (CFTA) 

Restriction on supply base: Due to the nature of the requirement, suppliers of the following countries are exclusively eligible to submit proposals: Canada, United States of America, United Kingdom, Australia, New Zealand.

Security: Also due to the nature of the requirement, certain information cannot be in the public domain. For this reason, security restrictions apply, as highlighted below. 

  • Resulting contractors must possess a Secret security clearance issued by the Canadian Industrial Security Directorate (CISD) of PWGSC.
  • Bidders must possess the clearance when submitting their proposal. 
  • Suppliers wishing to view Annex D of the solicitation must possess the clearance, must sign a non-disclosure agreement, must view the Annex on Canada’s site in the Ottawa, Ontario/Gatineau, Quebec region of Canada, and, cannot record the information in any form other than personal memory.

Suppliers are to submit viewing requests to the Contracting Authority.

QUESTIONS AND ANSWERS FROM THE SOLICITATION PROCESS:

Question 1:

We cannot find Appendix B. On what page is this appendix located? Is it not Annex D on page 72?

Answer 1:

Yes, this reference should lead the reader to the Annex D at page 72. We have amended this reference at page 32 of the RFP, as it should have indicated "Annex D" instead of "Annex B".

Question 2:

The contract is divided into two sites (location) – a Rx location and a Tx location. The RFP mentions that two separate bids needs to be submitted – one for each location. Broadly for each location, the requirement calls for a shelter and electronics. Is a bidder permitted to bid only for the electronics. In that case would that be considered compliant? By combining a shelter requirement in the polar region and electronics, small Canadian companies are at an inherent disadvantage as rarely would a Canadian electronics company have in-house capability or expertise for polar construction. For the transmit case, is it possible to bid without the power amps as these are COTS bought out items and can be provided by the government.

Answer 2:

No, all electronics including power amplifiers must be integrated into shelters. The Crown will move the shelter from Southern Canada to the final location in Northern Canada. The Contractor need only connect the shelter to Crown-provided antenna cables and power cables. Canadian Contractors are at an advantage because of a Canadian Content requirement (RFP 1.6, 4.1(d) and 5.1.2.1).

Question 3:

D-TA Systems is currently in the process of getting secret clearance (org number: 38481). Is there anything that can be done to expedite the clearance process so that we can ask for Annex B. Your help would be appreciated.

Answer 3:

No. PSPC cannot influence the timeline for processing security clearances, however, you are encouraged to communicate and follow-up with the Canadian Industrial Security Directorate (CISSD) client service centre.

Question 4:

Section 2 Rx (pg 44 of 72 to 45 of 72): Is the phrase “front-end” used to refer to a gain & filtering stage only (i.e., the analog-to-digital converter is excluded from the front-end)?

Answer 4:

Yes.

Question 5:

Section 2.2.3 Rx (Noise Figure): In the description provided, does this mean that the noise figure is measured/specified at a suitable gain so that the input power at the front-end input is -20 dBm (and this is the full scale level for the cascaded system)?

Answer 5:

Yes.

Question 6:

SFDR Rx (Section 2.2.4): Is this spec for the broad-band of the ADC or after narrowband DDC? A 100 dBFS spec (even if the wording suggests that this is at -10dBFS input power level) is an extremely difficult spec and will likely drive up the cost. Request that this be relaxed to 90 dBFS or thereabouts. Also, in the “complicated example” of the general information each of the two tones of the dual tone example is assumed to be 3 dB less than the single tone example. Conventionally ADC vendors specify that each of the two tones are 6 dB lower than the single tone case (adding in voltage as opposed to power). For example see a sample ADC data sheet (http://cds.linear.com/docs/en/datasheet/218543f.pdf page 11, for example).

Answer 6:

The spurious free dynamic range (SFDR) is measured after the analog-to-digital converter (ADC) and before the digital down-converter. As an example, the LTC2217 ADC is compliant with the SFDR requirement. The SFDR requirement includes both the front-end and the ADC. The “complicated example” is to illustrate the front-end.

Question 7:

Rx Operational Modes (Rx 1.3). The Mode 4 defines that the full rate ADC data (without any decimation) is sent to the remote recorder. This means that the data rate per channel is 200 MBytes/sec (100 MHz sampling, 16-bits ADC sample). For 1024 channels this translates to 204.8 GBytes/sec – A massive data rate. Assuming that each 10 Gbps link handles 800 MBytes/sec sustained (i.e., 4 channels raw ADC data), this means that 256 fibers are needed. Also, is the requirement to record this data at the remote recorder (Mode 4)? In section 2.4 the max data recording rate is defined to be 256 MBytes/sec. Thus there is a conflict. Is the intent that the raw ADC data from only a small number of channels will be transferred? Is there a requirement to record the raw ADC data (for these small number of channels)?

Answer 7:

In Mode 4, the 204.8-Gbyte/sec recorder is a future Government-furnished piece of equipment. The 256-Mbyte/sec recorder is Contractor-furnished and only used for Modes 1, 2, and 3. Mode 4 is intended for a future non-radar application.

Question 8: 

Transmit Op Mode (Tx Section 1.3). Same issue as in item 6 above (Rx op mode). The full DAC data rate will be much higher. Does the requirement call for transmitting raw DAC values from the player device? Again, assuming that 4 full rate channels per fiber the number of fibers needed for 256 channels is 64 fibers.

Answer 8:

In Mode 4, the 51.2 Gbyte/sec waveform generator is a future Government-furnished piece of equipment. The 64-Mbyte/sec waveform generator is Contractor-furnished and only used for Modes 1, 2, and 3. Mode 4 is intended for a future non-radar application.

Question 9:

For the remote modes of operation (Tx & Rx), is the assumption that the actual ADC / DAC devices are near the antenna (i.e., in the shelter).

Answer 9:

Yes.

Question 10: 

Clock & Trigger (Rx & Tx): Is the user going to provide sampling clock and trigger or are these signals considered internal to the system?

Answer 10:

These signals are Contractor-furnished (Statement of Requirement 1.1.6).

Question 11:

Phase Noise & SFDR for the Tx: Are these specs for the entire Tx chain (including power amps). If so these are extremely difficult specs to meet at 1kW power levels. Also, the harmonic spec for the power amp is specified to be -60 dBc. This is in conflict with the 90 dB SFDR (close in) & 70 dB (outside of the 100 kHz close in region).

Answer 11:

These are measured prior to power amplification.

Question 12: 

Inter-channel skew (Tx): Is this with the power amp. Can this is met via calibration?

Answer 12:

This is measured prior to power amplification and calibration is not acceptable.

Question 13:

Is there a mechanism in place that would allow us to contact interested tenderers to this project to offer our transmitter equipment? 

Answer 13:

There is no mechanism in place to contact interested tenderers to this project to offer your transmitter equipment to.

Question 14

  • 5.1.2.1 Canadian Content Certification - The Bidder certifies that: ( ) a minimum of 80 percent of the total bid price consist of Canadian goods and Canadian services as defined in paragraph 5 of clause A3050T.
  • Question 1 – if a bid is submitted with less than 80% of the total bid price consisting of Canadian goods and Canadian services, will it be evaluated regardless?
  • Question 2 – if all submitted bids have less than 80% of their total bid price consisting of Canadian goods and Canadian services, will they be evaluated?
  • Question 3 - if all submitted bids have less than 80% of their total bid price consisting of Canadian goods and Canadian services, and they are evaluated, are the bids with the greater percentage of their total bid price consisting of Canadian goods and Canadian services (albeit less than 80%) evaluated/scored higher?
  • Example 1 – Bid A and Bid B are evaluated relatively equal in all respects except that Bid A has 70% of its total bid price consisting of Canadian goods and Canadian services while Bid B has 50% of its total bid price consisting of Canadian goods and Canadian services. Is Bid A evaluated/awarded more points for having more percentage of its bid price consisting of Canadian goods and Canadian services than Bid B and is therefore selected as the preferred Bidder and recommended for award of a contract?

Example 2 – Bid A and Bid B are evaluated relatively equal except that: one, Bid A has 70% of its total bid price consisting of Canadian goods and Canadian services while Bid B has 50% of its total bid price consisting of Canadian goods and Canadian services and, two, Bid A has a higher evaluated price than Bid B. As a result of having the lowest evaluated price, is Bid B therefore selected as the preferred Bidder and recommended for award of a contract?

Answer 14:

Canadian Content is explained in Part 5 under article 5.1.2.1 “Conditionally Limited” and the Evaluation procedure is explained in Part 4, article 4.1(d). Generally speaking, these provisions, in conjunction with Part 4, article 4.2.1 “Basis of Selection” enable award of contract to a bidder whose proposal meets the Canadian Content (CC) requirement when two or more proposals each meet the requirement. The provisions also enable award of contract to a bidder whose proposal does not meet the CC requirement when less than two proposals each meet the requirement. Canada is not required to evaluate proposals not meeting the CC requirement when two or more proposals each include it. The CC Policy dictates that Canada prefer proposals meeting the CC requirement which includes award of contract.

Note that the RFP has requirements, apart from the Canadian Content, that must also be met for evaluation and selection purposes.

Question 15:

Request for bid extension – in order to effectively address the Canadian goods and Canadian services requirement to submit such a bid, we respectfully request an extension of 60 days to the current solicitation closing date of 26 Apr 2018.

Answer 15:

The RFP closing date has been changed from 26 April 2018 to May 28, 2018.

Question 16

We request confirmation from CANADA as to what artifacts need to be provided to demonstrate possession of a valid security clearance in order to receive the contents of Annex D. 

Answer 16:

To demonstrate a valid security clearance, Canada requires:

  •  the company legal name and security the clearance certificate identification number;
  • the name of the company’s representative(s) that will be accessing Annex ‘D’ along with their security clearance certificate and their date of birth; and
  • a photo ID will be required at time of viewing.

Question 17:

Due to the complexity and scale of Polar Over-the-Horizon Radar (W7714-186492/A) is there any possibility of extending the quote submission date?

Answer 17:

The RFP closing date has been changed from 26 April 2018 to May 28, 2018.

Question 18:

In reviewing Amendment 1 I noticed some minor errors as follows:

Page 32, 3.2 Appendix B should read Annex D.

Page 32, 4.1.1 it refers to Appendix B but I cannot find it unless it should read Annex D.

Page 36, 6.3.3 it should read Annex D.

Page 40, 8.1.1 Appendix B should read Annex D

Page 40, 8.2.1 Appendix B should read Annex D

Page 41, 8.3.1 Appendix B should read Annex D

Page 41, 9.7 Appendix B should read Annex D

Page 41, 11.2 Appendix B should read Annex D

Page 41, 12 Appendix B should read Annex D

Page 47, 3.2 Appendix B should read Annex D

Page 52, 3.2 Appendix B should read Annex D

Page 52, 4.1.1 it refers to Appendix B but I cannot find it unless it should read Annex D.

Page 56, 6.3.3, appendix D should read Annex D

Page 60, 8.2.1 Appendix B should read Annex D

Page 60, 8.3.1 Appendix B should read Annex D

Page 61, 9.7 Appendix B should read Annex D

Page 61, 11.2 Appendix B should read Annex D

Page 61, 12 Appendix B should read Annex D

Page 67, 3.2 Appendix B should read Annex D

A simple amendment would be to replace all Appendix B with the words Annex D.

Answer 18:

See RFP amendment 002 changes.

Question 19

Page 38, 6.4.6.1 confirm that the data to be recorded to an external media is only that of the radar operation.

Answer 19:

Yes

Question 20

Page 58, 6.4.6.1 confirm that the data to be recorded to an external media is only that of the radar operation.

Answer 20:

Yes

Question 21:

Have polar bear been spotted near the site locations?

Answer 21:

Yes

Question 22:

The solicitation closing date leaves little time for proponents to come together with a solid proposal with high Canadian content. Would it be possible to extend the closing date by a few weeks?

Answer 22:

The RFP closing date has been changed from 26 April 2018 to May 28, 2018.

Question 23:

The 80% Canadian content requirement is strongly supported. Would you consider awarding additional points for exceeding 80%?

Answer 23:

No additional points will be awarded for exceeding 80% Canadian Content

Question 24:

The RFP provides a breakdown of points for Technical rated requirements but does not contain an overall scoring formula e.g. 60% Technical, 30% Price, 10% Value Proposition. What is the overall scoring breakdown for this project?

Answer 24:

Part 4 of the RFP outlines the evaluation procedures that includes mandatory and point rated technical criteria with article 4.2.1 specifically outlining the basis of selection.

Question 25:

In appendix A section3.2 talks of the shelter location. I am not able to access the Appendix B, but this does affect the size of the shelter, and thus the maximum size of the equipment to install in the shelter.

Is there a maximum size for the pad located within this land area? If so what is the size?

Answer 25:

See RFP amendment. No. The key size constraint is that “…system equipment must be transportable by C-130 Hercules aircraft” (see Receiver site Appendix A Paragraph 3.4.1 and Transmit site Appendix A Paragraph 3.4.1). For shelters in particular, that means no larger than 6.10 m (20 feet) long by 2.44 m (8 feet) wide by 2.59 m (8.5 feet) high.

Question 26:

Question regarding the Point Rated Technical Criteria – applies to both the receive and transmit sites

In sections 4.1.1.2 (Point rate Criteria for Rx site) & 4.1.1.4 (Point rate Criteria for Rx site), the Minimum point for P1: Bidder Corporate Experience is 0 (zero). Is this a typo? This also means that no emphasis is being given on the three major technical aspects of this RFP – RF receivers, ADC/DAC and recorder/player. Is that a correct interpretation? Also, the minimums in the table add up to 33. Does this mean that bids must score the minimum in each line item as well as score a minimum of 40 (in aggregate)?

Answer 26:

The zero is not a typo. The receive site Evaluation Criteria does contain an error that is corrected under RFP amendment #3.

The wording has been corrected so that for a Bidder to obtain a non-zero score for Corporate Experience, the Bidder would have to demonstrate one or more projects that contain all of radio receivers, analog-to-digital converters, and data recorders. Bidders must obtain the minimum score in each line item as well as a minimum score of 40 in aggregate. The minimum aggregate score of 40 is larger than the sum of the minimums for the individual line items

Question 27:

The RFT specifies receiver (Rx) and waveform generators (WG) applicable to a band of interest from 3 MHz to 30 MHz, however amplifiers are specified from 3 MHz - 20 MHz. Is this correct?

Answer 27

Yes, this is correct. The range 20-30 MHz is deleted from the amplifier specification to reduce cost, given the polar location and low sunspot activity.

Question 28:

The ability of the PAs to withstand reverse power at a level of 500W whilst generating 500W of forward power is requested. Can you advise if this is considered to be i) a transient event before the PA self-protects or ii) whether this is to be withstood indefinitely? Is the reverse power reflected or coupled? Is the 500W at the output of the amplifier or at the antenna?

Answer 28

The 500 W of reverse power is for indefinite duration. It consists of both reverse power from each channel’s own antenna and coupled power from other channels’ antennas. The 500 W is measured at the amplifier.

Question 29:

In amplifier self-protection mode, if transient, is switching the antenna to a dummy load (open circuit) acceptable?

Answer 29

No, the reverse power is not transient.

Question 30:

There is no requirement on phase noise for the amplifier. Is this to be advised?

Answer 30

Although phase noise is specified before the amplifier, the out-of-band emissions after the amplifier need to be below -60 decibels-center (Transmit Site Appendix A Paragraph 2.4.5).

Question 31:

On the Transmit (Tx) site are connectors other than N-type able to be considered?

Answer 31

No, the cables are provided as type N.

Question 32:

The inter-channel time skew requirement is problematic. Notwithstanding time domain reflectometry techniques etc. the ability to phase match cables (ie: electrical length equivalence) is constrained by, for example: cable length measurement and cutting accuracy as well as practical connector termination. It is also influenced by handling, thermal (eg: -50 to +20 C) and bending characteristics that require phase matching with any accuracy to be adjusted by calibration. However in a previous clarification response calibration was not preferred. Can you advise a preferred method of phase matching on cables? Cable manufacturers we have worked with previously have suggested that their practical precision for supply of long length, phase matched cable, is in the region of 20 - 40 ns.

Answer 32

The time skew of 1 ns is specified at the input of the power amplifiers, and this specification is expected to be achieved without using calibration methods. After the signals go through the amplifiers/filters/cables of the various channels, it is expected that the time skew of 1 ns will be exceeded and that calibration will be required. The intent of the calibration is to produce a lookup table that can be used to adjust the programming of the signals going into the amplifier/filter/cables in order to achieve signals at the output of the amplifiers/filters/cables that also have a time skew of less than 1 ns.

Question 33:

At 1kW transmitted power, with a typically available 40% efficiency into a 50 Ohm load, with an A/B type amplifier, the available site power is exceeded even without consideration for other power load requirements (eg: heating, lighting etc). Alternative amplifier classes (eg: B) may allow for better efficiency, however signal linearity and performance will be significantly compromised. Are other power sources available?

Answer 33

No. Electricity is very expensive at site. There are no explicit specifications for linearity in the amplifier, so some gain compression can be tolerated to increase efficiency.

Question 34:

A transition zone is characteristic of both low and high pass filters. These have been requested for the Rx band of interest 3 MHz - 30 MHz. What is the extent of the transition zone for a model filter that is acceptable to allow for the whole band of interest to be covered?

Answer 34

While there are no hard specifications on the filters, the intent is to prevent entry of amplitude-modulation broadcast radio on the low frequency end (i.e. frequencies less than 1.7 megahertz) and frequency-modulation broadcast radio on the high frequency end (i.e. frequencies greater than 88 megahertz).

Question 35:

Can shelters be guyed (anchored) as required to meet wind loading requirements?

Answer 35

The Crown is not providing anchors and guys. Anchors cannot easily be put in the ground due to permafrost. If guys must be used, the Contractor needs to provide ground level concrete blocks and Styrofoam insulation to sit under the blocks.

Question 36:

Is the power cable from power source to shelter(s) supplied as Government Furnished?

Answer 36

Yes

Question 37:

Government furnished equipment does not mention fibre cables for mode 4 operations. Are these fibres provided?

Answer 37

Yes

Question 38:

Power is to be supplied as 3 phase. What is the construction of the cables? Are the individual phases broken out as separate cables or clustered together with neutral and earth as applicable?

Answer 38

At the receive site, the individual phases will likely be contained in a single armoured cable. At the transmit site, the individual phases will likely be broken out as separate armoured cables.

Question 39:

The air transport requirement, whilst only a contingency, would normally require an air transport certification. Is air transport certification required?

Answer 39

No. The air carrier only requires a declaration of Dangerous Goods (for example, lithium batteries).

Question 40:

For S-parameter measurement and matrix generation is it acceptable to measure element pairs serially whilst remaining elements are switched to a terminating load?

Answer 40

Yes.

Question 41:

With regard to phase coherence, at the start of waveform generation the NCOs for all channels must start from the same state to ensure phase coherence for all channels. However, timing pulse/trigger distribution systems and variations in analog paths contribute to phase inaccuracies. How is it proposed that phase coherence will be obtained, noting in answer to an earlier clarification question that calibration is not acceptable?

Answer 41

The time skew of 1 ns is specified at the input of the power amplifiers, and this specification is expected to be achieved without using calibration methods. After the signals go through the amplifiers/filters/cables of the various channels, it is expected that the time skew of 1 ns will be exceeded and that calibration will be required. The intent of the calibration is to produce a lookup table that can be used to adjust the programming of the signals going into the amplifier/filter/cables in order to achieve signals at the output of the amplifiers/filters/cables that also have a time skew of less than 1 ns.

Question 42:

Has modelling been done with regard Tx array radiation patterns that would inform placement of shelters and related equipment such that Radiation Hazard compliance is able to be achieved?

Answer 42

Yes. The Crown intends to keep the radiation level under 2 watts per square meter at the location of the transmit shelter(s).

Question 43:

What lengths of phase matched cable will be provided from both Tx and Rx array elements of connection to contractor supplied equipment?

Answer 43

The transmit site will use fixed 250 m lengths of LMR-900 cable for all antennas. The receive site will use varying lengths (up to 610 m) of LMR-400 cable for all antennas.

Question 44:

With submission of RFT responses (end April 2018) the indicated schedule suggests up to 90 days until award (ie: end July 2018). Factory acceptance test (FAT) is indicated as 12 months after contract award (ie: end July 2019) with site acceptance test (SAT) 16 months after contract award (ie: end November 2019) and with operations subsequent to that. Is this schedule considered feasible given the need to transport material to site, post FAT, with install to occur ahead of SAT given transport and seasonal restrictions? Is this schedule fixed?

Answer 44

The schedule is fixed. Increased transportation resources may be used if necessary to mitigate seasonal challenges.

Question 45:

For acceptance testing, is DRDC in possession of and able to provide representative transmit and receive antennae arrays in the Ottawa region suitable for Contractor integration and testing?

Answer 45

Comparable prototype arrays are available in the Ottawa area and the Crown would be open to providing them if there is no impact on contract schedule, there is no impact on Crown operations, and suitable frequency authorization can be obtained.

Question 46:

What artifacts need to be provided to demonstrate possession of a valid security clearance in order to receive the contents of Annex D beyond a signed Non-disclosure Agreement?

Answer 46

See RFP amendment #2

Question 47:

We asked for a 60 day extension, we meant 60 days beyond the original deadline of 26 Apr 2018, vice a 60 day bid period from the original RFP release date of 28 Mar 2018. In other words we were seeking an extension to 28 Jun 2018 vice 28 May 2018.

Answer 47:

Canada has considered all requests to extend the closing date of the RFP and have granted an extension to May 28, 2018.

Question 48

In our preliminary calculations for the Transmitter site power consumption, it appears that the power usage will be greater than the 600kVA. Is it possible to increase this limit to 850kVA?

Answer 48

No. Electricity is very expensive at site. As an illustrative example, if electricity is effectively 2 dollars per kilovolt-ampere-hour, then an increase of 250 kilovolt-amperes would represent an operating cost increase of 500 dollars per hour, which is costly for the eventual goal of an operational system running continuously.

Question 49

This is the power calculation that we were going with:

Power Available at 95% Power Factor: 570kW

Waveform Generation: 10kW

PA (based on current RFP spec @ 50% efficiency): 515 kW (256 * 2kW, rounded up)

Environmental control / Room etc: 45 kW

If you need the base PAs to operate at 1.4kW to account for the filter/combining losses (which is required) then at 50% efficiency the calculation is:

Waveform Generation: 10kW

PA (based on current RFP spec @ 50% efficiency): 720 kW (256 * 2.8kW, rounded up)

Environmental control / Room etc: 45 kW (* This may not be enough)

Total: 775kW = 820 kVA

Alternatively,

The clause:

2.4.1 Maximum output power

Each of the 256 channels in the power amplifier must have a maximum output power of no less than 1 kilowatt continuous wave.

General information: The maximum power output of the system is therefore 256 kilowatts, disregarding losses and mismatches in the antenna array.

Does the 1kW continuous wave refer specifically refer to the fundamental frequency or does it include the harmonics as well?

Does this mean that the losses after the power amplifier can be ignored? These losses would include the filter loss, loss of harmonic content, cable and connector loss, antenna array losses etc.

Answer 49

The 1 kW specification refers to forward power at the fundamental frequency. This power is measured after harmonic filtering, but before the coaxial cable runs to the antennas. A typical harmonic filter may have losses of 0.25 decibels, which means a forward power of 1060 watts at the input to the filter. This is within the range of single high-power transistor-pair amplifier pallets when gain compression is used, so there does not appear to be a need for power combining. A modular power amplifier unit with this capability is expected to have a current draw of less than 10 amperes at 208 volts alternating current. This would imply a total power draw of less than 533 kilovolt-amperes for all 256 amplifier modules. The remaining 67 kilovolt-amperes is expected to be adequate for the other equipment. In particular, no air conditioner is needed, because cool outside air is always available in the Arctic for cooling purposes.

Question 50

Is it possible to get a clearer copy of the SRCL as we wish to be certain of the requirements?

Answer 50

See Annex ‘A’ attached.

Question 51

Is the individual security clearance required mostly for the knowledge of the location of the site and to also gain access to the site?

Answer 51

The security clearance is needed for knowledge of the site locations. The Crown will not discuss specific site access requirements here because it may reveal site locations in an unclassified forum.

Question 52

Do individuals involved in the manufacturing of the equipment and shelters require the SECRET clearance if they are not made aware of the location of the site?

Answer 52

No

Question 53

Section 1.1, it now states the viewing location will be the NCR. However, I still feel it’s ambiguous in that the first paragraph in this section says [Canada will release the contents…] and the cover sheet of the latest Q&A from 10 Apr 2018 says the Classified Annex can “only be distributed upon request to Bidders who meet the security requirements”.
To properly review, understand and respond to the RFP, we need to do more than just look at the Classified Annex for a short period of time. We are not located in the NCR so visiting the office frequently to review the Classified portion is not realistic.

Are you able to re-review the requirements and make a determination as to if you can send us the Classified material via secure mail (e.g., double wrapped, labelled, etc. - in accord with ISM procedures)? Please advise asap.

Answer 53

The viewing of Annex D will be in the NCR. Canada does not anticipate a requirement for multiple visits to the NCR to view the document.

Question 54

6.4.5 Conduct site operations

6.4.5.1 The Contractor must provide resources to operate all functional components of the system, and maintain the system in an operational state, for 14 consecutive days at up to 12 hours per day.

How many 14 consecutive day operational sessions will there be in each year? Will there be a minimum amount of time between successive 14 day operational periods? Can you provide us with a notional schedule and timing of the 14 day operational periods please?

Answer 54

There is one operation per quarter (3 months).

Question 55

  1. Data storage capacity

The system must have a data storage capacity of at least 120 terabytes in addition to any space needed for software applications used by the system.

Note: Past experience with personnel endurance at remote sites has shown that operations generally run up to 12 hours per day for about 10 days, which requires about 120 terabytes of storage for data acquisition at a rate of 1 terabyte per hour.

It appears that requirements 6.4.5.1 and 2.4.2 have conflicting requirements as to the number of operational days. Is it 14 or 10 consecutive days?

Answer 55

Paragraph 6.4.5.1 is the requirement. Paragraph 2.4.2 contains an illustrative example of previous projects.

Question 56

Subject: Weight of the shelter

Requirements 3.4.1 Moving and 3.4.2 Lifting mention weight and lifting restrictions, but are not specific on the actual weight value.

For each site, what is the maximum weight capacity of the various equipment (sled, flatbed truck, forklift, crane etc.) that will be used to transport and lift the shelters?

Answer 56

There is a lift limit of 10,000 pounds (4,535 kilograms) for a single object. If necessary, the shelter can be shipped empty and the electronics shipped separately in boxes.

Question 57

Subject: On-site accommodations

For each site, how many contractor personnel do you have accommodations for?

Answer 57

Up to four.

Question 58

Bidder Team Definition

Question: Is the “Bidder” a single legal entity (either legal company or legal joint venture) and that the single legal entity must have all the experience, etc. on which the bid is scored within its own legal entity.

Answer 58

No.
