Gus Solomon Federal Courthouse Fire Alarm Design and Replacement

Scope of Work May 28 2013

The objective of this system replacement scope of work is to describe all the performance criteria expected at project completion in order to design and replace the current fire control panel(s), conductors and associated devices at the Solomon Federal Courthouse. The current fire panel that serves the Courthouse has reached the end of its useful life and needs to be replaced. The manufacturer of the current fire alarm panel and hardware is Simplex 2001 Life-Alarm.

This scope of work shall include the design and replacement of the fire panel, and all other fire life safety devices which upon completion will comprise a fully operational and code compliant system. In order to mitigate costs GSA will consider the reuse of some components such as tamper switches and flow switches, etc. depending on their operational condition, compatibility with installed system and current code compliance. If allowed, Contractor will be completely responsible for all reused system devices and they will be covered by same warranty as newly installed equipment. Project will consist of the replacement of complete fire alarm system to include all control panels, devices, wiring, and addition of new conduits and/or risers where necessary to ensure a fully functional, code compliant class “A” system when complete. Recent tests have been performed to determine current system wiring configuration. Test results attached.

The Gus Solomon is currently listed on the Secretary of Interiors historical register and therefore all work will be in compliance with the Secretary of the Interior standards for the treatment of historic properties, requirements of the Gus Solomon U.S. courthouse preservation plan and U.S. General Services Administration’s technical guidelines and contract documents.

No assumption of current systems code compliance should be made. Contractor will be responsible for complete design and installation which conforms to all current codes and standards.

The replacement of the fire alarm system will be accomplished while facility is fully occupied. The D/B Team will be required to ensure minimal disruption to tenants and their mission, keep a fully functional fire alarm system in operation, the facility and tenant’s safe and fully protected until such time as the new system is fully operational and ready to bring on line for facility protection. Phased installation of new system with facility being protected by more than one fire alarm system during project will be considered by GSA.

1. GSA envisions a highly collaborative D/B delivery approach for this project. The expectation is that the D/B Team will work closely with all the stakeholders to deliver a project that meets the expectations and needs of all stakeholders and GSA’s requirements for a fully functional, code compliant fire alarm system. Further, since this is a design/build retrofit project, there are existing fire alarm materials and/or equipment installed in the building. The Design Build Contractor shall include any missing materials and/or equipment in their project costs to ensure a fully operational, code compliant, Class ‘”A”, addressable fire alarm system.

2. Project documentation shall be provided by D/B contractor in the Meridian systems ePM format. Training and operating manuals for ePM system will be provided by GSA at no cost to successful contractor. D/B contractor will set aside time and assign individuals to take advantage of training at no additional cost to GSA within 30 days of NTP. The training is expected to take about 2 ½ business days to complete.

TESTING

Constructor shall be responsible for all quality control related to all phases of project. Contractor will provide quality control plan to GSA for review before any design or on-site work begins. Any and all work deemed unsatisfactory by GSA and/or AHJ shall be replaced or repaired at the discretion of GSA.

Manufacturer's Field Service: Engage a factory-authorized service representative to inspect field-assembled components and connections and to supervise pretesting, testing, and adjustment of the system. Report results in writing.

The completed system shall be subjected to two required tests. The initial test shall be a preliminary test which will be witnessed by the GSA Property Manager’s representatives. Should the results not be satisfactory to the GSA Contracting Officers Representative, then corrections will be made and a re-test will be required at the contractor's expense. A contractor's representative and contractor supplied fire alarm technician shall be present for all tests. The fire alarm technician shall conduct the tests.

The preliminary test shall be in accordance with a written Acceptance Test Procedure (ATP) to demonstrate and certify proper system operation. The ATP shall be prepared by the contractor and submitted to GSA for approval six (6) weeks or more prior to the performance of the ATP. As a minimum, the ATP shall provide a detailed method of testing the following to demonstrate to the GSA that the systems function as intended by the design:

A point-to-point test for each alarm initiating and indicating device, the operation of the elevators recall system and the operation of door holder releasing mechanisms. A test of the batteries shall be completed at the end of the point-to-point test.

Interface with smoke control system, Smoke evacuation system, fire pumps and associated ATS(s), and any door locks affected by fire alarm system shall be tested and correct operation confirmed.

Upon the successful completion of the preliminary test, the final acceptance test can be arranged. It shall be witnessed by the representative of the GSA Regional Safety and Environmental Section (AHJ). The test shall prove the Class A features of each device, which will include the removal of each alarm initiating device from its mounted position and placing it in an alarm condition, open circuit condition & ground fault condition for both positive and negative sides, alarm condition while in the open circuit condition and alarm condition while in a ground fault condition. The alarm indicating devices shall have the class A features tested, which will include the removal of up to 100% of the devices as chosen by GSA and placing the device in an open circuit condition, ground fault condition for both positive and negative sides and sending an alarm signal while the device is in an open and ground fault condition. Each auxiliary system that is affected by the fire alarm system shall be tested to ensure the proper operation and supervision (i.e. elevator recall system, closure of door hold open devices, etc.).

The following items shall be required beside the requirements as a minimum for the preliminary resting of the system.

Perform a mega ohm meter test for each circuit prior to connecting the devices and record the results of the test. A copy of the test shall be forwarded to GSA via ePM for their records. Copies of the mega ohm meter tests shall be received by the contracting officer prior to starting the acceptance test.

All detectors shall be removed from their mounting boxes. A wire shall be lifted from each detector, one at a time, to verify proper supervision of the devices.

Up to 100% of all audible alarm devices shall be removed from their mounting boxes. A wire shall be lifted from each device, one at a time, to verify proper supervision of the devices.

All bypass and control switches shall be operated to indicate proper supervision of the switch.

All valve and sprinkler supervision switches shall be operated to verify proper response.

All valve and supervision switches shall have one wire removed to verify proper supervision.

Each alarm output, detection and supervision zone will be tested for proper response to ground conditions.

The supervisory transmitter shall be tested for proper operation.

All zone enunciator transmitters shall be tested for proper operation.

All critical fuses shall be removed to check for proper supervision.

All detectors shall be tested for alarm operation.

All flashing light units shall be tested for class ‘A” wiring supervision by removing a wire from the device. The device shall also be tested for proper alarm operation.

All alarm sounding devices shall be tested for proper operation.

Audibility tests shall be conducted to determine compliance with the audibility requirements of this specification. A copy of the space layout drawings for each level of the building shall be used to record the audible levels through-out the building. The audible test shall be done using a sound level meter and performed in the presence of the GSA Construction Management Team. The results shall be forwarded to the GSA Regional Fire Protection Engineer for review to determine if any additional speakers are required prior to the beginning of the final acceptance test.

All elevator, door holder control functions and circuits shall be tested for proper supervision and operation.

Test each initiating and indicating device and circuit for proper operation and response at the control unit.

Test the system for all specified functions in accordance with the contract drawings and specifications and the manufacturer's operating and maintenance manual.

Test both primary power and secondary power. Verify, by test, the secondary power system is capable of operating the system for the time period and in the manner specified.

Determine that the system is operable under the trouble conditions as specified.

Visually inspect all wiring.

Verify that all software control and data files have been entered or programmed into the FACP. Hard copy records of the software shall be provided to the contracting officer.

Verify that as-built drawings are accurate.

Measure the current in circuits to assure there is 25% spare capacity for the circuits.

Measure the current in circuits to assure that voltage drop is not excessive.

Disconnect the verification feature for smoke detectors during testis to minimize the amount of smoke or test gas needed to activate the detector.

The requirements for final testing shall be as requested by GSA via Contracting officer and GSA Fire protection engineer (Authority Having Jurisdiction) AHJ. Should the results not be satisfactory to the GSA Contracting Officers Representative, then corrections will be made and a re-test will be required at the contractor's expense to include all costs for GSA AHJ.

In addition to all aforementioned testing, there will be a requirement for a 10% test of entire system at 24 months. The same process as previously mentioned in this section will apply.

CLEANING AND ADJUSTING

Cleaning: Remove paint splatters and other spots, dirt, and debris. All debris must be cleaned up daily to ensure occupied spaces are ready for tenant occupancy. Touch up scratches and marred finish to match original finish. Clean unit internally using methods and materials recommended by manufacturer. All damage to existing finishes will be repaired before project is accepted. Any and all repairs to historical finishes will require acceptance by SHPO and “no adverse effect” concurrence will be required before repairs will be accepted by GSA.

TRAINING

The contractor, within two weeks after final acceptance test and system has been accepted by GSA shall conduct a training session during which all maintenance and operational of the system will be described and demonstrated to personnel selected by the government. The time of the sessions shall be agreed upon by all parties and shall be conducted by the manufacturer's representative that is thoroughly familiar with the characteristics of the installed system, preferably the individual who accomplished original system programming.
