Installation of High Spec Automatic Sliding Gates and Control System Upgrade, Embassy Vehicle Access CAC A & CAC D

Introduction

The U.S. Embassy requires the design, supply, fabrication, removal of existing equipment (where applicable), installation, testing, and commissioning of automatic sliding gate systems at two Embassy vehicle access points: CAC A and CAC D, both used for vehicle security checks.

For CAC D: The work includes replacement of the existing gate leaves, rails, wheel assemblies, motors, and replacement of the control system within the security booth, along with perimeter fence height modifications and security enhancements.

For CAC A: The work includes refurbishment of existing gate leaves, installation of new maintainable guide wheels and equipment, replacement of gate motors and controls (similar to CAC D specifications), proper disconnection of gates from the existing hydraulic system while preserving the hydraulic system for continued Delta barrier operation, and installation of a new control system. Critical requirement: The existing hydraulic system must remain fully functional for Delta barrier operation and must not be damaged or compromised in any way during gate system modifications.

Both systems must be suitable for frequent daily operation, provide enhanced perimeter security, and be designed for long-term maintainability with locally serviceable components. Both locations shall include fiber optic connections to Post 1 for secondary remote control capability.

Background

CAC D: The existing vehicle access gates are in urgent need of replacement and are no longer fit for proper and safe operation. The current gates rely on a single hydraulic system that is beyond its working life span, resulting in increasing failures, reduced reliability, and elevated operational risk during security screening operations. The existing gate leaves and guiding mechanisms are aged, heavy, and difficult to maintain. These conditions increase the likelihood of unplanned downtime and create safety concerns for operators, pedestrians, and vehicles using the checkpoint.

CAC A: The existing vehicle access gates consist of one interior and one exterior sliding gate that require comprehensive refurbishment and system upgrades. While the gate leaves may be retained and refurbished, the current hydraulic operating system for the gates, guide wheels, and control equipment are outdated and require replacement to improve reliability, maintainability, and operational safety. The existing hydraulic system at CAC A serves dual purposes: operating the sliding gates and operating the Delta barrier. The hydraulic system must remain in place and fully operational for the Delta barrier. The Contractor must carefully disconnect only the gate-related hydraulic connections while ensuring the Delta barrier hydraulic system remains completely intact and functional. This is a critical security requirement as the Delta barrier provides essential vehicle access control at this checkpoint.

Current Environment

CAC D: The vehicle access point is a high use security location where vehicles are stopped and screened prior to entry. The current gates are heavy and the existing mechanical and hydraulic arrangement limits effective maintenance and timely part replacement. Existing rails, guides, support steelwork, and interface points to the surrounding fence line exhibit age related wear and corrosion and are not aligned with the requirements of a modern high cycle gate system. The surrounding infrastructure in the gate area requires modification and refurbishment to remove weak points, address corrosion, and support the installation of new top and bottom rail guidance and independent industrial duty motors.

CAC A: The vehicle access point features one interior and one exterior sliding gate serving as a critical security checkpoint. The current hydraulic system operates both the sliding gates and the Delta barrier. The gate-related hydraulic components and guide mechanisms are outdated and difficult to maintain. The existing control system requires replacement. The hydraulic infrastructure serving the Delta barrier must remain fully operational and undamaged throughout the project. Supporting structures require refurbishment or replacement to ensure long-term reliability and proper integration with new motorized gate systems. The Contractor must exercise extreme care to identify, isolate, and preserve all Delta barrier hydraulic components, lines, controls, and connections.

Objectives

Overview

The objective of this SOW is to acquire high quality automatic sliding gate systems at both CAC A and CAC D that improve reliability, safety, maintainability, and perimeter security at Embassy vehicle access checkpoints. The Contractor is expected to deliver robust solutions that support high frequency operation, integrate into the existing fence structures without vulnerabilities, and include new control systems compatible with current operational procedures and remote-control requirements from Post One via fiber optic connections.

The scope of work includes site verification, engineering design, fabrication, refurbishment and modification of surrounding support infrastructure, removal and decommissioning of existing gate equipment, installation of new sliding gate leaves, replacement of all surrounding fence and structure to 2.2-meter height, installation of security spikes on gates and fence, installation of new top and bottom rail and wheel systems, installation of independent industrial-duty motors, replacement of the control system in the security booth, fiber optic installation from CAC D to Post 1, completion of all required electrical works, testing and commissioning, training of Government personnel (Facilities, Marine Security Guards, and FAC staff), and submission of complete handover documentation.

CAC A Scope:

The scope of work includes site verification, engineering design, refurbishment of existing interior and exterior gate leaves, refurbishment or replacement of all gate supporting structures (posts, rails, foundations, fence interfaces), installation of new maintainable guide wheels and equipment, careful disconnection of sliding gates from the existing hydraulic system with absolute preservation of hydraulic system integrity for Delta barrier operation, installation of new independent industrial-duty motors (same or similar to CAC D specification), installation of new control system in CAC A security booth with preservation of Delta barrier control functionality, fiber optic installation from CAC A to Post 1, completion of all required electrical works, testing and commissioning including verification of Delta barrier functionality, training of Government personnel (Facilities, Marine Security Guards, and FAC staff), and submission of complete handover documentation.

CRITICAL CAC A REQUIREMENT: The existing hydraulic system serves both the sliding gates and the Delta barrier. The Contractor must:

· Identify and map all hydraulic components, lines, valves, actuators, and controls serving the Delta barrier versus those serving only the gates

· Disconnect only the gate-related hydraulic connections, components, and controls

· Leave the Delta barrier hydraulic system completely intact and operational

· Ensure no damage occurs to any Delta barrier hydraulic components, lines, seals, fittings, or controls

· Cap, plug, or properly terminate any hydraulic lines that served the gates to prevent contamination or leakage

· Verify Delta barrier functionality before, during, and after all gate modification work

· Coordinate all work with the COR and demonstrate Delta barrier operation at key project milestones

Failure to maintain Delta barrier functionality is considered a critical project failure and may result in contract termination and liability for all damages.

Common Requirements for Both Locations:

The Contractor shall design and install the gate systems to meet all operational, safety, and security requirements, including mandatory measures for fall-over prevention, run-out prevention, and entrapment prevention.

Gate leaves shall be designed to prevent fall-over in the event of disconnection, component failure, or maintenance activities. Each gate leaf shall incorporate posts, stanchions, bollards, or a self-supporting structural design that prevents the gate from tipping more than 45 degrees when disconnected from supporting hardware. For opposing sliding gates that close at the center (CAC D), the Contractor may satisfy this requirement through a self-supporting box-frame design, typically with a frame depth of not less than 300 millimeters, such that each gate leaf is capable of standing independently without reliance on a center post.

Sliding gates shall be provided with run-out prevention measures to prevent uncontrolled travel beyond fully open or fully closed positions. This shall include positive mechanical stops at both the fully open and fully closed positions designed to withstand the maximum forces imparted by the gate during normal and fault conditions. All sliding gates shall also be equipped with limit switches that prevent travel beyond programmed operating distances. Existing run-out prevention components shall be inspected and replaced or upgraded as necessary to meet these requirements.

Entrapment prevention shall be incorporated throughout the entire gate travel path. Each gate shall be equipped with a minimum of two independent safety devices. One safety device may be integrated into the gate motor or operator to sense resistance or abnormal slowdown. A second independent safety device shall be installed on the interior side of the gate and shall consist of a photo eye, infrared sensor, light curtain, edge guard, or an approved equivalent. Any space between the moving gate and a fixed surface along the entire length of gate travel that is less than 410 millimeters shall be treated as an entrapment zone and shall be protected by appropriate sensing devices. Where gate run-out areas are accessible to personnel or the public, including interior compound-side areas, the Contractor shall provide physical barriers, fencing, or walls with a minimum height of 1.2 meters to restrict access.

All surrounding infrastructure, including foundations, plinths, fence interfaces, and support steelwork, shall be refurbished or modified as required to remove corrosion, eliminate weak points, and ensure the new installations do not introduce security vulnerabilities. The new gates shall integrate seamlessly with the existing perimeter fence, providing continuous security coverage with no gaps, footholds, or climbable features.

The completed systems shall be designed for ease of maintenance and long-term serviceability. Wheel assemblies, wear components, motors, and safety devices shall be accessible for inspection and replacement with minimal disassembly. All components shall be corrosion resistant and suitable for continuous outdoor operation. Component standardization between CAC A and CAC D installations is strongly preferred to simplify maintenance and spare parts inventory.

The expected result is fully commissioned, high-cycle automatic sliding gate systems at both CAC A and CAC D that operate smoothly, safely, and reliably, support Embassy security operations without interruption, and meet all FAC, OBO, and Embassy operational requirements. At CAC A, the Delta barrier must remain fully functional throughout and after all project work.
