Questions & Answers – 29 Jul 08

1) The PLC description on sheet E-21 under the heading, Supervisory Control Panel, states Allen Bradley’s Compact Logic controller. With this unit, modules cannot be removed under power. Specification page 44, 2.12.6 states ‘the digital I/O modules shall have the capability of removal and insertion under power’. This implies the use of Allen Bradley’s Control Logics controller which is quite a bit more expensive. Please provide direction.

Response: “Hot Swapping” of modules is not a mandatory requirement for this job, but the specifications still require it. If an amendment cannot be issued because of time constraints the Contractor will have to bid to the specifications. Amendment 0002 will be issued on 29 July 2008.

2) Per addendum #1, item 16, coordination meetings will be required to develop various features of the requirements. Where will these meetings take place? We assume at the area office in Kaukauna.

Response: The meetings will take place at the Corps’ Area Office in Kaukauna.

3) Rockwell’s product called Factory Talk can do every thing the specs call for, but the remote alarm-email-autodialer function is no longer part of their software. They use a third party software package called WIN911. This will work, but the specs call for a ‘package software suite’. Do you think this would this disqualify Factory talk as the HMI software?

Response: As long as all software furnished meets the functional requirements of the system this should not present a problem.

4. I have some questions regarding the video poles that I would like clarification on.

1) What are the poles to be constructed of – steel or aluminum?

Response: The poles and base are aluminum with powder coating. The design is based on a Video Alarm PV18N lowering pole.

2) What finish – galvanized, powder coated?

Response: Powder Coated.

5) I see reference to speakers, there are PA speakers to be mounted on the existing light poles – are there speakers on the video poles?

Response: No speakers on the camera poles just the camera and the LED infrared illuminators.

6) The weight of the equipment would determine a lot regarding the poles, that is not specified.

Response: Since the Contractor is providing the video equipment he will have to determine the pole loading requirements.

7) What is the transfer base to be constructed of, and what size is it?

Response: The transformer base is the same material as the camera pole powder coated aluminum.

8) Please clarify the type of cable for the cameras. The drawings show cat5, but the specs call for coax. Which is correct?

Response: Both cables are correct. It depends on how the contactor intends to wire the camera back to the video recorder. The cat5 and coax are used for camera control and video respectively. If he uses what's called a Balun then everything can be sent over the cat5 cable. If he furnishes an TCP/IP pan-tilt-zoom camera then Cat5 is used. If he uses a camera with "Up-the-coax" control then just a coax is required.
