1.0 GENERAL

1.1 PROJECT DESCRIPTION

The Request for Proposal (RFP) provides parameters for a design-build project for construction of an Entry Control Facility (ECF) in Graf Ignatievo Military Base, Bulgaria; Latitude 42°16'53.5"N, Longitude 24°43'47.0"E (Refer to the attached Location Map.)

Layout of the new ECF is based on the “Stop Control AVB Safety Scheme” as per SDDCTEA Pamphlet 55-15 providing one rated active vehicle barrier as final denial barrier. This will allow for safe deployment of the barrier by guard response within 5 seconds in case a vehicle is trying to intrude the base (see Att. # 3).

The new ECF shall only serve for POV processing. A separate truck gate is located elsewhere on the base. However, the approach and the access control zone of the ECF shall accommodate larger vehicles to allow for turning of vehicles rejected at the ID-Check including trucks that may have entered the ECF by mistake. Besides Passenger cars, the ECF shall accommodate emergency vehicles, vans, and small buses.

The new ECF shall consist of an Approach Zone including an entry gate provided by a cable reinforced double swing gate, passive vehicle barriers, asphalt road alignment and walkway connection up to the ID Check area.

The following Access Control Zone shall consist of a raised paved traffic island, a barrier wall for protection of the guards, an optional guard booth, a drop arm, and passive barriers.

Proposed Asphalt pavement shall accommodate ID-check lane, outbound lane, and vehicle rejection.

The proposed response zone shall consist of passive vehicle barriers, asphalt road alignment up to the connection with the existing road system, and the final denial active vehicle barrier.

A second ID-Check Lane providing vehicle search capability is proposed for optional expansion.

24-Jul-23 Page 3 of 34

Foundations to expand the ECF with an optional canopy for the ID Check area shall already be constructed in the scope of this project.

Command and control features as well as visitor control center functions shall be provided in the existing gatehouse.

The existing gravel parking in front of the existing gate shall remain to provide visitor parking.

The ECF shall be provided with lighting and with electric power & telecommunication systems as necessary for the implementation of the “Stop Control AVB Safety Scheme” as per SDDCTEA Pamphlet 55-15.

Sufficient space shall be retained for future extension which may include a new visitor parking and a new building of 12.5 m x 8.0 m footprint provided with aprons and accommodating and combining gatehouse & visitor control center functions.

Design Demand for the ECF is calculated to be 600 vehicles per hour based on traffic data provided by the customer. Provision of 1 ID-Check Lane and the optional 2nd lane is expected to prevent vehicles from cueing into the access road at Force Protection Conditions that match US DoD FPCON Bravo.

An additional Limited Use Gate shall be provided in location of the exiting gate that is controlling access of military trucks to the road south of the new ECF connecting to the existing fuel farm in the west.

The Limited Use Gate shall consist of a cueing area provided by existing pavement, new cable reinforced fencing to separate the gate from the Base by perimeter protection, and a cable reinforced swing gate serving for access control. The Limited Use Gate shall be protected by operational procedures only.
