RFI No. Request for Information: VA/(A/E Watson Engineer) -provided Response:

Question - 1.

Please specify What type and size of coax cable will be installed to the antennas in build 1 & 37.

1- All coaxial cable for the radio system shall be in accordance with spec section 27 32 41.D.1 and manufacturer requirements, whichever are more stringent.

Question -2.

How will the dispatch console slated for the firehouse get its connectivity to building 37 IT Room?

2- No wiring will be required in this location the network will be there and coordination with the VA OIT department to ensure network is available will be coordinated by COR.

Questions: 3.

In building 37 can the cable be installed in free air after the attic. Can we use the existing cable tray

3- Yes, once the cable leaves the attic area, the existing cable tray may be used. All cabling within the attic shall be installed in conduit.

Question - 4.

Will there be a staging area for construction materials?

4- Yes, This is an item for after award to indicate the staging area location.

Questions: 5.

Will the awarded contractor be responsible for the disposal of all the demo material? Will the contractor be able to dispose using a VA dumpster or by other means on the property?

5- Yes, The contractor responsible to dispose all equipment being removed that has not been indicated on the plans for VA to keep. The contractor responsible to provide dumpster.

Questions: 6.

The Construction drawings call out ¾ in conduit for the coax cable in building 1 &37. Conduit size will be contingent on coax cable size. Can the VA suggest a conduit size? The existing conduit in building 37 attic looked to be 1 ½.

6- Replace conduit in B37 attic "in kind" with 1-1/2" conduit.

Questions:7.

Does the VA have a spec for the four-post rack referenced on E-101 – Key note 4?

7- Please clarify request - keyed note #4 on E-101 calls for a NEMA L5-30P receptacle. Note that stand alone open equipment racks are specified in spec section 27 11 00.2.1.D.

Questions:8. Section 27 and E-601 Section 27 32 41 (page 418) Expansion Capability Section 2.1.C - We mention possibilities to expand as our system is easily expandable. However, there is wording here that the system has to be capable of expanding by 50% without additional internal or external components or main antenna or trunk cable conductors. That is impossible. Should expansion be necessary, additional radio equipment will be required.

8- No additional equipment is required for this project beyond what is shown on the E-601 diagram and equipment list.

1. General Questions/Comments

Pre-Proposal - Request for Information 1 AE Works Ltd.

Questions:9. Section 27 and E-601 There are a lot of statements about Telephony. We have only included the recording of 3 (non-VOIP based) phone lines into our logger. Can we get the VA to explain what their expectation is around all of the telephony statements? Are they looking for a single headset to control both radio and telephony? I ask because the system we proposed cannot do that. ?

9- There is no expectation to control both radio and telephony with a single headset.

Questions:10. Section 27 and E-601 Also, there are a lot of statements around paging technology. We do not have any paging integration with the radio system.

10- No paging integration is required.

Questions:11. Section 27 and E-601 Diagram E-601 - States there are 3 dispatch consoles in building 37 and 1 dispatch console in building 16. Assuming building 16 is more than 300ft away for an ethernet connection, will the GC be responsible for running/trenching fiber from 37 to 16?

11- No wiring will be required in this location the network will be there and coordination with the VA OIT department to ensure network is available will be coordinated by COR.

Questions:12. Section 27 and E-601 Diagram E-601 - States there are only a total of 4 dispatch consoles in 2 different rooms (Security Service Control Room and Fire Dispatch Room), however in Section 27 32 41 (page

428) Section 2.5 Remote Control Equipment Paragraph C, it states that each console should be provided in the Security Service Control Room, Engineering Service Room, MAS Room and location(s) show on the drawings. Are there more dispatch consoles required? If so, how many? Also, if so, is the GC responsible for connectivity between the core equipment in Building 37 IT Room to each of these rooms?

12- No additional dispatch consoles are required, beyond those identified on the diagram on E-601.

Questions:13. Section 27 and E-601 Diagram E-601 - Offers one APX8500 Base Station to Fire to replace their existing Base Station.

Is this separate from the newly required Dispatch Console listed in Diagram E-601? Or are we to use the base station as another interop channel solely for VA Fire? We are trying to understand if VA Fire wishes to dispatch from a console like VA Police or an APX8500 Base Station.

13- A new dispatch console shall be provided at Building 16. This console will require connectivity to building 37 IT room. No wiring will be required in this location the network will be there and coordination with the VA OIT department to ensure network is available and in compliane with manufacturer requirements, to be coordinated by COR.
