Dear Applicant:

Please be advised that we have made a general review of the drawings, calculations, and equipment data for the proposed Fire Suppression System, based on the submittal package received for the above referenced project.  This review is governed by the Official Manual of the Office of State Fire Marshal, which contains the adopted laws, codes, rules, and regulations of this office.  This review, in no way, shall permit and/or authorize any omissions or deviations from the specific requirements of the Official Manual.  Requirements cited in this review do not relieve the licensed fire suppression system designer and the Professional Of Record, when required by LA RS 37, from complying with all the requirements contained in the Official Manual.  Subsequent to our general review of the submittal package, we have determined that the drawings, calculations, and equipment data appear to satisfactorily comply with the adopted laws, codes, rules and regulations of the State Fire Marshal, subject to the following requirements and review qualifications:

NOTE:  THE 2003 EDITION OF THE NFPA 101 LIFE SAFETY CODE APPLIES FOR THIS REVIEW. (DISREGARD THE 2006 REFERENCE ABOVE.)

NOTE:  THE COMMENTS LISTED BELOW IDENTIFY APPARENT DEFICIENCIES DETECTED IN OUR REVIEW OF THE DOCUMENTS SUBMITTED.

1.	13R: 6.6.7.2.1  Sprinklers outside of the dwelling units shall be quick response and selection shall be based on the requirements of  NFPA 13, Standard for the Installation of Sprinkler Systems, except where permitted by  6.6.7.2.2.

	a)  13: 8.4.2 Sidewall Spray Sprinklers. Sidewall sprinklers shall only be installed as follows:
(1) 	Light hazard occupancies with smooth, horizontal or sloped, flat ceilings 
(2) 	Ordinary hazard occupancies with smooth, flat ceilings where specifically listed for such use
(3) 	To protect areas below overhead doors

The deficiency is that the DS-1 dry sidewall sprinkler indicated in the Storage Room needs to protect a room width exceeding 10 ft, but is not listed for ordinary hazard.  A change to the DS-3 or other sprinkler may be needed. 

2.	ANSI A17.1 Sprinkler protection in Elevator Hoistways, Machine Room s, or Machinery Spaces shall comply with the following: 

c)	Rule 102.2(c)(3)  Means shall be provided to automatically disconnect the main line power supply to the affected elevator upon or prior to the application of water from sprinklers located in the machine room or in the hoistway.  This means shall be independent of the elevator control and shall not be self-resetting. 

-  The deficiency is that neither is a pre-action valve is indicated in the supply to the sprinklers in the Elevator Equipment Room nor is a  high temperature sprinkler indicated which can be coordinated with low temperature heat detectors.  (See also Rule 102.2(c)(4)  Sprinkler activation in elevator machine rooms and hoistways by smoke detectors is prohibited.)  ( 13: A.8.14.5.4  Sprinklers within 2 ft. of the bottom of the pit are exempted. ) 

______________________________________________________________________________________

NOTE:  THE FOLLOWING COMMENTS IDENTIFY ISSUES FOR INFORMATIONAL AND CAUTIONARY PURPOSES OR ISSUES THAT COULD NOT BE VERIFIED IN THE SUBMITTED DOCUMENTS.

3.	This letter voids and replaces our review of April 29, 2008, Project Number P0337993. 

4.	This fire protection system review is limited to the original plan review scope as per State Fire Marshal letter P0324475.  

5.	This review applies to the automatic residential sprinkler system, for compliance with NFPA 13R, 2002 edition, as shown on the drawings for the above referenced project. 

6.	This review is based on a project supplied by a city water supply of 70 psi static and 56 psi residual pressure, flowing 1245 g.p.m. through an 8 inch circulating city main; test indicated as performed by Firetrol (only on the calculation summary sheet), on 10-23 (or 24)-07. 

7.	13R: 6.7.2.2  The system demand in the area outside the dwelling units, in the 3rd Floor Supplies room is  indicated as follows:

	a)  55 psi and 88 gpm at the base of riser (backflow preventer outlet) and 57 psi and 88 gpm at the source; allowing 13 psi "margin"; corrected only to delete outside hose allowance, which is not required by NFPA 13R.

	b)  The system demand was based on a density of 0.20 gpm/ft2 over the discharge area of four sprinklers.

	c)  The calculations include 2.5 psi residual pressure loss, based on installation of the following backflow preventer: Manufacturer: Ames, Type: Double Check, Model Number: 2000SS, Size:  3 inch, at the base of riser. 
	
8.	13R: 5.3.2  Piping in areas  that can not be maintained reliably above 40 deg. F. shall be protected by use of one of the following methods:  (1) Antifreeze system, (2) Dry pipe system,  (3) Preaction system,  (4) Listed standard dry-pendent, dry-upright, or dry-sidewall sprinklers extended from pipe in heated areas.

	a)  13R: A.5.3.2  Piping covered by insulation, as shown in  Figure A.5.3.2(a) through  Figure A.5.3.2(e), is considered part of the area below the ceiling and not part of the unheated attic area.

	b)  13R: 5.3.2  Where insulation is used to define the piping, which is located in attic spaces, as being part of the area below the ceiling, verify that piping is installed directly on top of joists or truss bottom chords and batt insulation having a sufficient "R" factor is secured over the piping so as to thoroughly isolate the pipe from the cold area, that insulation is not placed between the pipe and the heated space, and that the space below the pipe is maintained heated at all times during freezing conditions. 
	
9.	Although written response, describing resolution to the comments regarding the sprinkler system in this review letter, which do not affect the hydraulic design as submitted, are not required to be submitted back to this office, the Professional of Record, (when required by LA R.S. 37:155) otherwise the Owner, shall not be relieved of the requirement to comply with all citations indicated in this letter, as well as all requirements of the Official Manual of the Office of State Fire Marshal, Code Enforcement and Building Safety.

For example, if the letter requires that sprinklers, materials, or devices be changed, added or relocated in certain areas which would not affect the hydraulic design, installation of the sprinklers or devices needed to conform with the requirements of the referenced section of the Code or Standard is adequate.  Correspondence and acknowledgement would not be needed.  If, however, the additions or relocations cause revisions to the system calculations or result in significant changes to the sprinkler or piping sizes or layout which can not be communicated on a simple sketch or which require replacement of the reviewed drawings, a re-submittal, with fee, would be required.

10.	Two sets of drawings and two sets of calculations were received for review, and were returned in the following manner:

	a)  One set of drawings and one set of calculations were marked by review as "set 1 of 2", and, bearing the State Fire Marshal Review stamp on the drawings, were returned to the applicant.

	b)  One set of drawings and one set of calculations were marked by review as "set 2 of 2", and, bearing the "Copy... Not Be Used For Compliance Verification" stamp, were returned to the fire suppression system sub-contractor. 

Changes to construction in the field which are not consistent with the reviewed documents are not authorized unless reviewed by this office for compliance with Code.  Modifications to reviewed plans must be submitted to this office by the Architect/Civil Engineer for review prior to final inspection.  If an Architect or Civil Engineer is not required by RS 37:155, revisions shall be submitted by the Owner.  Submittals shall include plans, completed application, a minimum $55.00 review fee, and a copy of the most current plan review letter.

Occupancy of the project is permitted only upon the receipt of the applicable Contractor's Material & Test Certificate as per NFPA 13, Fire Alarm System Certificate and Description as per NFPA 72, or other certification as required by the applicable codes and a satisfactory inspection of the completed construction had been made by this office.

To arrange for inspection of the project, please contact the District Office at the phone number below two (2) to three (3) weeks in advance.  The plans stamped reviewed by this office must be available on job site at time of inspection.  Certificate of completion must be provided to the inspecting Deputy for final inspection.

This review is valid for 180 days from the date of this letter.  Construction permits must be issued and/or construction must commence within this time period.
