TECHNICAL QUESTIONS AND

With the revised price schedules both labeled as A.3, one is provided for a total lump sum number and another one requires us to break out each individual building. Are we required to fill out both the lump sum portion and the building break-down?

Please fill out the revised price schedule as specified in 36C77626R0008 Amendment 0005.

Is the revised CLIN Structure for accounting purposes only? Requesting break-downs by building is very atypical, as we have bid multiple EHRM projects which have multiple buildings without providing a building break-down cost. We are more accustomed to having a lump sum divisional breakdown than a per building break-down. Subcontractors are also reluctant to provide pricing in such a fashion. Please advise

Independent Building Readiness / Phasing EHRM activation often occurs on a building-by-building basis.

Breaking CLINs out by building allows the government to:

· track progress

· authorize payments for completed phases

· report status of each building separately

Question 365 states the existing structural drawings are provided, please confirm where these drawings are? They are not in the B21 drawing set provided when the solicitation was advertised and are not included in the addenda.

See 36C77626R0008 amendment 0007 – Attachment 2 for Building 21 as build drawings.

To confirm the current Fire Alarm System installed by Edwards and serviced by Everon is a Siemens Fire Alarm system and all existing equipment will be compatible with the new components installed within the new TR rooms.

The equipment installed in the TR Rooms must be compatible with the existing Fire Alarm System identified.

In the RFI answers sent last week, you answered the big question earlier that there is a BAS component to this job, which is helpful. And I found one note on a drawing that states the BAS is Tridium Niagara4. However, I do not know what manufacturer is specified, nor the scope of work (what units need to be tied to the BAS).

I attended the site visit and asked the COR to show me the BAS equipment. All he was able to find was the enterprise server that the Jaces connect to.

Is there any way for me to speak with someone in Fayetteville who has knowledge about the BAS and the EHRM project to answer my questions. I believe this would be of keen interest to you and the project.
