## 1.03 SYSTEM DESCRIPTION

A.  Design

1\. The designer of the fire protection systems shall meet one of the
requirements below.

a\. A registered Professional Fire Protection Engineer in the State of
New Mexico.

b\. Minimum National Institute for Certification in Engineering
Technologies (NICET) Level III for wet-pipe or dry-pipe, Ordinary
Hazard, Group II Sprinkler Systems, regardless of size.

c\. Minimum NICET Level IV for all other types of systems, including
special hazard protection.

d\. Where NICET design is used, copies of the designer\'s certificates
from NICET shall be submitted along with the drawings for approval. The
registered Professional Engineer shall stamp all other plans.

e.  The contractor is responsible for the design and installation of the
    fire protection system, including seismic supports, in accordance
    with these specifications and the contract drawings. The contractor
    shall coordinate with architectural, civil, mechanical, and
    electrical, design and construction documents, to ascertain the
    required information, to effect a properly designed fire protection
    system for the building construction and occupancy classification.

2\. The design of fire protection systems shall be complete with all
necessary accessories for proper operation. System design and
installation shall reflect high quality professional work that properly
accounts for practical maintenance concerns and aesthetic concerns, as
well as meets the design density requirements. Departures from this
standard of professionals including inefficient designs, unnecessary
materials, and special system modifications to meet design density
(e.g., reduced spacing the hydraulically remote areas) shall be avoided.

3\. The fire protection water supply lines, controlling devices,
protective devices, alarm systems, supervisory devices, and related
equipment shall be compatible so that all equipment will function
together as specified.

4\. The design shall comply with all mandatory, advisory
interpretations, and recommended applicable rules of the latest editions
of the referenced codes and standards in Part 1.02, \"References,\"
except where otherwise noted on the drawings or specified herein.

5\. The contractor shall produce design drawings (design files) that
indicate the extent and arrangement of the fire protection systems.

6\. Unless indicated in the contract, drawing(s) refers to the plotted
hard copy document or print and the electronic computer aided drafting
design (CADD) file.

B. Design Criteria

Entire building shall have fire protection, based on the following
design criteria:

1.  Light hazard occupancy rules shall only be implemented at the
    discretion of the designated representative of SANDIA/NM Fire
    Protection Engineering.

2\. Pipe schedule method shall be permitted only for additions or
modifications (less than 3000 -feet² (278.71-m²) to existing Ordinary
Hazard Pipe Schedule systems. All other designs shall be hydraulically
calculated.

2.  Hydraulic calculation methods shall be used as a minimum for
    Ordinary Hazard, Group 2, wet-pipe systems, unless otherwise
    specified. The minimum operating area allowed shall be either 1,500
    feet² or the entire area for smaller systems.

3.  All systems requiring the installation of a backflow prevention
    device shall be hydraulically calculated as a reduced pressure
    backflow preventer regardless of what backflow device is specified
    on the contract drawings.

The following table indicates the required sprinkler designs for various
occupancies at Sandia/NM. These shall be used unless otherwise specified
on the Bid Drawings.

1\. Place calcium hypochlorite in pipe sections when installing pipe or
inject liquid chlorine into the system via the injection port. Pipe is
filled with water and chlorine concentration shall remain at 10 mg/l for
a minimum of 24 hours. During this time, all valves in new section will
be cycled open and closed to allow for adequate disinfection. Valves
connecting the new or repaired line with mains in active service shall
remain closed to prevent chlorine pollution.

2\. Samples shall be drawn at 1-, 4-, 8-, 12-, 16-, 20-, and 24-hour
marks to determine the chlorine concentration. Acceptable tests are the
N-diethyl-p-phenylenediamine (DPD) drop dilution method (AWWA C651,
Appendix A) or the High Range Test Kit. The tests shall be done by the
contractor and witnessed by the SDR. The results shall be recorded for
auditing purposes.

C. Slug Method:

1\. Similar to the continuous feed method. Follow AWWA C651. Chlorine
concentration to be 100 mg/l for a minimum of 3 hours. During this time,
all valves shall be cycled open and closed to allow for adequate
disinfection. Valves connecting new or repaired lines with mains in
active service shall remain closed to prevent chlorine pollution.

2\. Samples shall be drawn every 15 minutes to determine concentration.
Acceptable tests are the DPD drop dilution method or the High Range Test
Kit. The tests shall be conducted by the contractor and witnessed by the
SDR. The results shall be recorded for auditing purposes.

D. Repairing or Cutting into Existing Mains:

1\. New interior piping surfaces shall be swabbed with a one- percent
hypochlorite solution. The section being modified shall be subjected to
a high chlorine disinfection process per AWWA C651. The concentration
shall be a minimum of 300 mg/l for 15 minutes.

2\. Samples shall be drawn before the chlorine is injected and every 5
minutes thereafter. Chlorine concentration shall be tested by the
contractor or SDR designee using the High Range Test Kit. SDR shall
witness the test and results shall be recorded.

E. Flushing:

1\. After the lines have been chlorinated using one of the above
methods, it becomes necessary to flush the lines with water until test
sample indicates that the water is suitable for drinking. The residual
chlorine concentration in the water is to be between 0.2 and 2.0 mg/l,
as measured using a Low Range Test Kit. The test shall be witnessed by
SDR or other SDR designee and the results recorded.

2\. Heavily contaminated water shall be disposed of or neutralized under
the direction of SANDIA/NM Pollution Prevention and Environmental
Monitoring Department.

F. Bacteriological Testing:

1\. All new and modified water lines require testing for coliform
organisms per AWWA C651. The testing shall occur after successful
chlorination and flushing of the lines. Samples shall be taken from the
new line in sodium thiosulfate treated sterile bottles and analyzed as
specified by APHA's Standard Methods for the Examination of Water and
Wastewater. Analysis, at the discretion of the SDR representative shall
be performed by SANDIA/NM Industrial Hygiene or an independent
laboratory.

2\. Results shall be recorded with the original documentation of results
attached. These will be used for auditing purposes.

3\. Fire protection lines will not be accepted until a negative
bacteriological test is performed. Lines will be chlorinated and flushed
repeatedly, at no additional cost to SANDIA/NM, until such a negative
test is accomplished.
