Letter No M&U-13-0062 dated 28 November 2013 shows 3 conclusive comments from KAUST on the 90pc DD package. Our responses are given below:

1.	Access to last section of island is not included in the original scope of work as approved by KAUST. Project Change Request (PCR) is required by KAUST for change order to be executed.
2.	Intrusion detection systems under the Wadies are not included in the scope of work as approved by KAUST. Nevertheless the necessary security measures were discussed during the technical review meeting and the following was agreed and shall be implemented.
a.	Security grills shall be added to culvert cells on the upstream side in coordination with flood control project.
b.	Crash rated bollards shall be installed on the wadi bed on the upstream side in coordination with the flood control project.
c.	The location of guard houses (currently at top of the culvert) shall be relocated to the downstream side of the wadi, so that a direct observation/view on the cells of the culvert is available.
3.	The arrangement of the layers follows the HCIS standard where the anti-vehicle layer is provided before the intrusion detection layer. HCIS mentions that the two layers cannot be overlapped and shall be contiguous. The project designer has considered all options, all relevant standards and available space limitations and chosen the current arrangement. Any changes to the proposed arrangement shall require KAUST to provide more land on the North and South side of the perimeter. KAUST has not provided a technical reason within the relevant standards to prove that the designers preference is wrong and thus any changes to the arrangement are not possible not only due to the standards but also due to lack of space. IFC based on the approved project proposal shall be due on December 01, 2013 and key drawings shall be provided to KAUST. Any changes required after the issuance of IFC shall require a change order request.
