The High of all doors is 280 cm. The high is not standard. During site visit I have noticed that the high of all doors is approximately 200 cm and the part above 200 cm, is fixed, as non-movable part of doorframe. Please for Clarifications!

Answer:

Yes, all doors shall be with passable standard high of min. 200 sm. Please read the doors/windows schedule in graphic file. Upper section is fixed as non-movable panel.

Highs of construction opening is according to dimensions on site, and we find that will be difficult to construct secure wall above door, so adjustments on doors shall be done as in drawings. In any case, existing openings shall be closed with tight, secure fire barrier (doors + frames)

Please to clarify: DVR should be 16 - channel ore 4 – channel, because this can have significant impact in the pricing!

Answer:

DVD recorder shall be for 16 cameras: 3 or 4 inputs from rooms who are in our scope of works, and rest are for existing cameras on site (existing system can’t be upgraded, so this is replacement for old one).

Next line in bill of quantities is an error (line with 4 inputs) and has been replaced with E.51.
