3.1

FIELD QUALITY CONTROL

A. Hydrostatic Tests:

1. Piping to be Tested: The purpose of this section is to define the required testing

procedure for the dedicated fire protection underground piping. The dedicated fire

protection underground piping shall be defined as all fire protection underground piping:


12/22




a. Downstream of the terminal flanged joint of the double check valve backflow

prevention assembly gate valve in the hot box (see drawing and APPENDIX B),

and

b. Upstream of the wall Post Indicating Valve in the Base Building Fire Pump Room

(see attached drawing and APPENDIX B), and

c. Upstream of the hydrant main valve (see drawing and APPENDIX B).

2. The hydrostatic test shall be conducted during non-freezing weather periods.

3.

The test pressure shall be gradually increased in a controlled manner until the minimum

acceptable test pressure is achieved. The initial pressure increase shall be to not more

than 50 psi. The subsequent pressure increase shall be to not more than 100 psi.Thereafter, incremental pressure increases of not more than 20 psi each shall be applied

to the system. Each pressure increase shall be held for a minimum of ten (10) minutes,

and the system shall be observed over its entire length for any signs of leakage before the

next incremental increase in pressure. If significant leakage and associated pressure drop

is identified at any time during the test, the test will be terminated. Final test pressureshall be 200 psi minimum. Test pressure nominally in excess of 200 psi will be

acceptable. Test pressure shall not exceed 220 psi. The expected duration of the

hydrostatic test process is eight (8) hours.

4.

Test Process

Refer to APPENDIX A, RECOMMENDED SEQUENCE OF EVENTS Day of Test,

for recommended step by step instructions for conducting the hydrostatic test. The

Contractor shall review the instructions and provide constructive modifications, if any,

for FAA review and approval. The Contractor shall prepare a detailed Test Procedure for

review and approval by the FAA. The detailed Test Procedure shall be signed by the

Contractors license holder or officer of the company, and by the NICET III certified

technician (one signature will be acceptable if the individual is the license holder/officer

and is NICET certified). The detailed Test Procedure shall incorporate the following, at a

minimum:

a.

IDENTIFICATION OF SYSTEMS TO BE IMPAIRED: All impaired systems

shall be identified by implementing proper lock out-tag out procedures for each im-

paired system. The following fire protection systems will be impaired due to the

hydrostatic test of the fire protection underground piping:

i.

Fire Detection and Alarm system. The system will be placed in test mode,

such that signals automatically transmitted to the Remote Supervising Station

will not be processed until notification is provided that system test status is

concluded. Note that local fire detection and alarm functions will operate nor-

mally; only off-site communications will be affected by the hydrostatic test.

ii. Fire Pump/jockey pump system. This system will be impaired during the hy-drostatic test, and remain impaired until the test is completed and all systems

restored to normal operating condition.

iii.

Automatic sprinkler and standpipe systems. Although the recommended se-

quence of operations will provide for pressurized water to remain in the sys-


13/22




tems, these systems will be impaired during the hydrostatic test, and remain

impaired until the test is completed and all systems restored to normal operat-

ing condition, or until alternate water supply is provided for the systems.

iv.

Stairwell pressurization system. As this system is controlled by the fire detec-

tion and alarm system, it will be impaired during the hydrostatic test to the

same extent as the fire alarm system, and remain impaired until the test is com-pleted and all systems restored to normal operating condition. Manual actua-

tion of the stairwell pressurization system will be possible at the fire alarm con-trol panel during the hydrostatic test.

v.

Fire Protection Underground Piping. This system will be impaired due to

valve closures and joint disconnections at the hot box and at the Base Building

Fire Pump Room, and remain impaired until the test is completed and all sys-

tems restored to normal operating condition.

b.

INTERIM LIFE SAFETY MEASURES: During hydrostatic testing activities, it is

likely temporary hazards may be posed due to the work being conducted at the fa-

cility. Interim Life Safety Measures (ILSM) are actions that must be taken to com-

pensate for the temporary hazards. Implementation and enforcement of ILSM is theresponsibility of all occupants within the building, including employees and con-struction/testing personnel. However, primary identification of hazards and the ac-

tions taken to compensate for temporary hazards are the responsibility of the Con-

tractor. All ILSM are subject to approval by the FAA.

i. Prior to commencement of testing, conduct a meeting, to be coordinated viaCOTR, during normal working hours to inform all Tower and Base Build-

ing occupants (employees and construction personnel) of the project scope

and duration. This should include, at a minimum, the following:

1.

An overview of the testing project.

2.

A preliminary schedule for the construction.3.

Discussion of affected fire protection and life safety systems in-

cluding active and passive features.

4.

Discussion of the effect on daily and emergency operations.

5.

Demonstration of signs, messages, etc. to be used to identify haz-

ardous conditions and the corresponding ILSM.

6. List of contacts for reporting hazardous conditions.

ii. The Contractor shall provide appropriate signage, in a location(s) approved

by the FAA, to notify occupants of current activities and ILSM in effect at

the facility. The signage shall be verified prior to each construction shift

and employee shift. The signage shall indicate the present hazards and the

safety measure(s) provided to compensate for the hazards.

iii.

The facility fire alarm system will not be fully operational during this test-

ing, due to other fire protection system impairments. The Contractor shall

provide, at a minimum, the following additional ILSM:

1. Inform the fire department of the impairment of the facility firealarm system and inform them of the ILSM being taken to com-

pensate for the impairment.

2.

Fire Watch. The contractor shall notify the COTR and ensure a

plan is in place to notify the occupants of the ATCT and the Base


14/22




Building, and the Chicago Fire Department in the event of a fire

during the impairment. In order to achieve occupant and fire de-

partment notification in these instances, a fire watch is necessary.

The Fire Watch service, plan and personnel shall be approved by

the FAA prior to the hydrostatic test.

iv.

If the testing activities result in the use of temporary ignition sources (hotwork), i.e. welding, cutting, plumbers torch etc., the Contractor shall com-

ply with OSHA 29 CFR 1910.251-252 and provide, at a minimum, the fol-lowing ILSM:

1.

Inform the COTR of hazardous operations.

2.

Keep a log of all hot works activities.

3.

Provide the appropriate type fire extinguisher to the personnel per-

forming the work (all construction personnel shall be trained in the

proper use of fire extinguishers prior to the commencement of

work).

B. Determination of Pass / Fail

1. Primary Criteria: The primary criteria for passing the hydrostatic test are to pressurize the

portion of the system to be tested to a pressure not less than 200 psi (13.8 bar), and to

maintain that pressure without loss for a period of not less than 2 hours.

2. Alternate Criteria: the hydrostatic test can be considered to have passed by comparison to

the maximum allowable leakage identified in the referenced standards. See NFPA 13

10.10.2.2.4 and NFPA 24 10.10.2.2.4. Except for the potential termination of the test

as directed by the COTR due to the observation of significant leakage and associated

pressure drop, this alternative test procedure is intended to be conducted concurrently

with the primary test procedure, and the process of determining the volume of water

required to restore the initial test pressure shall immediately follow the 2 hour test period

of the primary test procedure. This alternative test procedure will be pursued only if thebasic criteria identified in item 1, above is not achieved

Allowable leakage is identified as a function of the number of joints in the tested piping,

at a maximum rate of 2 quarts/hr (1.89 L/hr) per 100 gaskets or joints, irrespective of pipe

diameter. Given that the length of pipe run is approximately 740 feet and 70 joints are

estimated, 2 quarts/hr (1.89 L/hr) for two hours, or a total of 4 quarts (3.78 L) will be

considered the maximum allowable leakage. If 1 gallon or less is required to restore the

system to the initial test pressure, the test will have passed. If more than 1 gallon is

required to restore the initial test pressure, the test will have failed.

The amount of leakage in buried piping shall be measured at the specified test pressure

by pumping from a calibrated container (i. e., the two hour test duration will begin whenthe test pressure is 200 psi or higher. If the pressure drops during the test, at the end of

the two hour test period the system will be re-pressurized to the initial test pressure by

pumping water from a calibrated container so that the volume of water required to restore

the initial test pressure can be determined).

C. Prepare reports of testing activities.

Times and associated test pressures shall be recorded as follows:


15/22




1.

System static pressure before test.

2.

Time and pressure for each incremental increase until minimum test pressure (200 psi) is

achieved (start time).

3.

Time and pressure at 15 minute intervals during the minimum 2 hour test period.

4.

Time and pressure at end of 2 hour test period (end time).

5.

System static pressure after testing is concluded, and all systems are fully restored.

6.

(If alternative test is performed, only):

a.

Time and pressure for each incremental increase until minimum test pressure (200 psi)

is achieved (start time).

b.

Time and pressure at end of 2 hour test period (end time).

c. Time and quantity of water required to restore test pressure to start time pressure.

D.

Restoration of the system to the before test condition, removal, of any impairments, and

confirmation that the fire protection systems are fully operations.
