The U.S. Army, 411th Contracting Support Brigade, RCO Daegu is issuing this sources sought synopsis as a means of conducting market research to identify parties having an interest in and the resources to support the requirement for the annual maintenance services for firefighting aerial ladder in South Korea.

PROGRAM BACKGROUND

The U.S. Government desires to procure of the annual inspection, maintainance, and test for the aerial ladder trucks.

- Descretion of Services o Scope of Work

The Contractor shall provide all personnel, equipment, tools, materials, supervision, and other items and services necessary to perform operational tests and inspections on Aerial devices.

The Contractor shall provide services for testing and inspection on the aerial ladders. The contractor shall develop a four-part integral phase testing and inspection regiment to ensure that the aerial firefighting equipment being used by the Government (Fire and Emergency Services, Fire Station, Yongsan, Humphreys, Daegu, Camp Carroll) is safe and reliable while responding to emergency situations. The Contractor shall perform required services in strict compliance with the National Fire Protection Association (NFPA) 1911 Section 22 and all other terms and conditions contained herein

Tasks Visual Inspection o The contractor shall examine each aerial device for compliance with the manufacturer’s guidelines along with the National Fire Protection Association standards. Visual inspection of the equipment is intended to detect visible defects, damage, or improperly secured parts. The visual inspection shall be conducted prior to any operational or load testing and shall be carried out in a systematic sequence with proper attention to detail.

STD: Compliance with the manufacturer’s guidelines along with the National Fire Protection Association standards.

AQL: 100% Compliant Non-Destructive Tests o The contractor shall use non-destructive testing methods to detect defects that are sub-surface in nature and not detectable in the visual inspection. All test procedures shall be consistent with ASTM E 1316, Standard Terminology for Nondestructive Examinations. The non-destructive tests will consist of:

(1) Magnetic Particle Inspection

(2) Eddy Current Inspection

(3) Ultrasonic Inspection

(4) Thickness Tests.

o STD: Consisent with ASTM-E-1316, Standard Terminology for Nondestructive Examinations ASNT CP-189 o AQL: 100% Compliant Operational Tests o The contractor shall perform operational tests to determine whether the hydraulic system, safety systems, and structural mechanisms are operating in a normal manner. Placed on a hard level surface, the aerial apparatus is taken through a sequence of operational cycles. Any abnormal condition will be noted.

IAW NFPA 1911, 22.8.2 - 22.8.11. Some Areas of Inspection are as follows:

- Turntables and Controls

- Torque Box (when applicable)

- Suspension

- Tractor – Drawn Components (when applicable)

- Platforms and Controls

- Ladder Section Components

- Boom Components

- Complete Hydraulic Systems

- Interlock and Safety Systems o (a) STD: National Fire Protection Association standards 1911

AQL: 100% Compliant Functional Tests o The contractor shall check the controls, bearings, pins, bushings, cylinders, holding valves, ladder extension cables, platform leveling mechanisms, outriggers, and waterways. The contractor shall inspect for worn swing bearings/gear boxes, worn pins/bushings, and loose bolts that are critical to the operation of the aerial device.

o Tests and Measurements Include:

- Alignment

- Cylinder and Winch Drift

- Level Measurements

- Thickness and Corrosion

- Timing Test

- Rotation Bearing Tolerance

- Hydraulic System Analysis

- Hydraulic Oil Analysis

- Engine Oil Analysis (if needed)

(a) STD: National Fire Protection Association standards 1911

AQL: 100%

- Contractor Qualification o The Contractor shall be able to meet ten (10) listed standards and codes used in manufacturing and testing of Aerial Device Equipment.
