IC is urged to understand that the subject project is a security related project and it is IC responsibility that project is delivered in accordance with all requirements of the contract. Responses to your letter are given below;

a. SAPMT letter L-315 clearly mentions whats written in the specifications.i.e. ACI for design and and K-ratings for performance. ICC can not deny the fact that K-rating is explicitly mentioned in the specifications. It is IC responsibility to meet the K-ratings mentioned in the specifications. K-ratings are driven from a certian standard which requires testing to be done and does not rely on design only.//b. Also ICC can not deny the fact that HCIS standards are mentioned in the specifications which refer to the relevant ASTM standards. //c. Please study SAES-O-21, Application of Security Directives, which relies completely on HCIS.//d. Appendix D in scope of work, refers to ACI for design standards but also requires K-ratings to be met. IC has to prove how the walls are K-rated. Appendix D also requires grade beams to be constructed under K-rated walls, which IC has neglected and will be considered a negative change order. According to SCH-B, 3.1.1 absence of comments from SAPMT does not relieve IC from performing its obligations under the scope of work. Additionally, K-ratings are related to crash testing are not just about vehicle loads only. K-ratings are based on the maximum penetrating distance measured from the front-most edge of a vehicle’s truck bed to the backside face of the barrier after impact. The shorter the truck bed’s penetrating distance, the higher the barrier’s performance level will be to stop vehicular intrusions and the longer the blast "stand-off distance". No design standard can prove K-rating unless a crash testing standard is used to prove it. Appendix D also refers to all ASTM standards for testing materials and also Saudi Arabian standards like HCIS.// Any claims related to neglecting the proof of K-rating of the Walls can not ignored and hence IC claim for not testing the walls is rejected.
