STATEMENT OF WORK/SPECIFICATIONS

DATE:

PROJECT:

Phase 1 & Phase 2, - Luanda, Angola

SERVICES:

Kitchen Hood Fire Suppression System

1. BACKGROUND AND PURPOSE

a. The U.S. EMBASSY Luanda , Angola and Overseas Buildings Operations (OBO) Fire Protection Division has a requirement to survey the existing hood system in Phase 1 and to fix and modify the current Ansul R-102 Fire Suppression System for the existing kitchen hood system in Phase 2. This requires a qualified technician by Ansul to perform the survey and then make modifications according to US standard mechanical industry practices and Ansul standards/requirements.

2. GENERAL REQUIREMENTS

a. The Contractor shall provide personnel, material, equipment, and supervision to complete the technical requirements in this Statement of Work. The Contractor shall be responsible for labor, equipment and shall follow security and safety directives as explained by the U.S. Embassy Contracting Office and RSO.

b. The Contractor shall have limited access into the structures and outside the areas designated for the project except with permission by the Embassy Contracting Officer and RSO. The Contractor shall address the impact of the consequent disruption and provide for a continuing level of operation of the Chancery functions caused by the proposed work.

c. Design and Application The restaurant/kitchen fire suppression system shall be designed to provide fire protection for restaurant/kitchen cooking appliances, hoods, and ducts. It shall be a pre-engineered group of mechanical and electrical components for installation by an authorized distributor. The basic system shall consist of an automan regulated release assembly, which includes a regulated release mechanism and a liquid agent storage tank housed within a single enclosure. Nozzles, detectors, cartridges, liquid agent, fusible links, pulley tees, and pulley elbows are supplied in separate packages in the quantities needed for each fire suppression system. If existing install is missing items noted in “C” it shall be noted upon survey report and priced.

The system shall provide automatic actuation; or it can be actuated manually through a remote manual pull station. The gas or electric supply to all protected appliances will be immediately shut off upon actuation of the system, using appropriate gas shut off or electric shut down devices. The unit shall also include electrical contacts, so the system can be monitored by the building main fire alarm panel upon activation of this unit showing an alarm condition. Upon activation it shall also show the location of the alarm condition on the fire alarm control panel (FACP). All FACP work will be done by OPS/FIR/FPS.

Additional equipment includes: remote manual pull station, mechanical and electrical gas valves, switches, and electrical switches for automatic equipment and gas line shut off. A set of contacts shall be supplied for fire alarm notification for current FACP panel. Once activated it shall indicate an alarm condition.

The system suppresses fire by spraying the plenum area; the filters, cooking surfaces, and the exhaust duct work system with a predetermined flow rate of low pH liquid fire suppressant. When the liquid agent is discharged onto a cooking appliance fire, it cools the grease surface, and reacts with the hot grease forming a layer of soap like foam on the surface of the fat. This layer acts as insulation between the hot grease and the atmosphere, thus helping to prevent the escape of combustible vapors.

Exhaust fans in the ventilating system should be left on. The forced draft of these fans assists the movement of the liquid agent through the ventilating system, thus aiding in the fire suppression process. These fans also provide a cooling effect in the plenum and duct after the fire suppression system has been discharged. The system shall be UL listed with or without fan operation. (Not part of this scope) It is also required that make up of supply air fans be shut down upon system actuation. Shutdown of fuel and power to all appliances located under protected ventilating equipment is required upon system actuation.

(Not part of this scope) It will also be required that the installing contractor furnish training and instruction to the local staff on proper operation and maintenance of all functions of the newly installed systems. The installing contractor will also be required to furnish all installation manuals and maintenance manuals upon completion of the modified units.
