While maintaining optimum security measures for the subject project, there are some areas where certain elements of the perimeter security system can be eliminated to save time and money, some of which are given below;// 1. The ditch construction in the shared security corridor between the Naval base and Kaust can be eliminated, as both sides are considered high security zones and no intrusion from either side is anticipated. The length of the proposed ditch elimination is approximately 0.55 kilometers starting from 0+000 to 0+300// 2. The ditch construction along the flood control channel can be eliminated for a distance of 1.2 kms starting from 9+200 to 9+750. The perimeter security system runs adjacent to the flood control channel and the channel serves as an oversized ditch. // 3. Because of continuous presence of security staff at the main gates and also to avoid the view of the 5m wide ditch from the public entering the gates, it is proposed that atlast 200m of ditch on both sides of the two main gates be eliminated. This will eliminate 800m of ditch construction (excluding access to gatehouses) from 6+800 to 7+300, 7+850 to 8+300.// Removal of LPRS (License plate recognistion system) at gates 2 and 3, since it merely captures the number but is not capable of triggering alerts.//Removal of UVIS since its manyually viewed and operated and does not provide a comparison between the underside of a clean and a tampered vehicle.
