  • Materials – pipe schd’s, sprinkler styles…
  • Execution – coring, fire stopping…
  • Great in theory doesn’t always happen

Q

Specifications can come in different formats

A

• CSI Format to Notes on drawings
• Large projects/contractors may have their own specifications
• There have been modifications to the CSI format
• Master Format 95TM
• An upgrade to the CSI format
• Master Format 2004TM

Q

Bidding Process

A 
There’s different possibilities:
1. The contractor bids based on specs and plans prepared by
the architect or engineer
• Building Information Modelling (BIM)
• Typically will require a FP engineer/designer to make the FP drawings
• conceptual
• Based on the building code review
• SFP drawings
2. The contractor prepares their own drawings
• Require lots of information
• Water supplies
• Occupancy
• Hazard classification

Q

The Estimator

A

• Read and interpret specifications properly it requires
training and experience
• Read all the specs
• Know the scope of work

• Any ABC allowances due to sprinklers
• Insurance/owner requirements
• Open or closed – substitutions allowed?
• Any addendum
• Ensure you know type of building and occupancy
• ABC review tells lots
• Who is the AHJ

Q

Once awarded

A

• The parties enter into a contract, (typically signed) – It’s a legal document
• prepare design drawings
• Working plans are developed from preliminary drawings and
specifications
• Submit to AHJ for approval
• ABC requirements and drawings Division C 2.2.3.1, 2.4.2.3
• NFPA working drawings requirements chapter 27
• Have water information, including hydraulic calcs
• Designers must refer to other trades drawings
• HVAC, plumbing, electrical, structural
• Go to typical specifications pg 12 – great for review

Q

Blueprint Reading

A

• Blueprints, including sprinkler plan, elevation, cross section and
detail drawings, are an important source of information when
planning a sprinkler system installation
• As a sprinkler system installer, you need to develop the skill to
extract information from these different drawings
• Develop the skills to determine
• what you need
• where to find it
• Dimensioning is important
• Dimension off known points

Q

General Notes

A

• Notes are used to convey information that can not be
illustrated.
• Be sure to read and understand all the notes to avoid costly
mistakes!
• Notes are used to convey the specifications
• Symbols are used in order to simplify/de clutter the
drawing.
• The meaning of the symbols can be put in a legend that can be
referred to.
• Note: the symbols are not always the same from drawing to
drawing
• Familiarize yourself with the other trades relevant symbols

Q

Divisions of Blueprints

A
  1. Architectural Blueprints – designated by the ‘A’
    • Usually, first in the package with a drawing list
    • Architectural prints provide information regarding the layout and
    construction of the building
    • Other than the Fire Protection drawings the Architectural drawings
    are probably the most important for the sprinkler installation
    • Ceiling heights
    • Ceiling types
    • Wall types
    • Light locations
    • Smoke and fire alarm locations
    • Finishes

Q

Site Plans

A

Site plans shows the entire area on which the building will
be built (the footprint)
• Location of the structure on the site.
• Larger scale than the Floor Plan shows entire area 1:500 or 1:200
• Elevations.
• Contour lines – may be important when installing underground.
• Direction of the drawing – where is north? to construction north.
• Existing underground piping such as water, hydrants, valves, gas, and electrical.

Q

Foundation plan, Floor plan, Elevations, Section Drawings

A

• Foundation Plan - shows the location of footings, pilings, and grade beams that will support the structure.
• Floor Plan - the building’s interior, as seen from above.
• locates the walls, doors, windows, plumbing fixtures, appliances,
electrical fixtures, switches, and more.
• Elevations - detail the building’s exterior, as seen from the outside. FDC
• Section Drawings - detail the building’s interior, shown as a cutaway
• Use the ‘cutting plane line’

Q

Detail drawings, interior elevations, window door and finish schedules

A

• Detail Drawings - show a close-up of information that can
not be adequately portrayed using the scale on the main
drawing.
• Interior Elevations - similar to exterior elevations, but
are used to show details such as kitchen cabinetry,
bathroom fixtures
• Window, Door, and Finish Schedules
• wall types
• Window and door types
• many items can be found within the schedules

17
Q
  1. Structural Blueprints
A

show how the building is put
together
• Gives details on columns, beams,
• often the gridlines are based on the structural

18
Q
  1. Mechanical Blueprints
A

include plumbing, HVAC, and fire protection systems
• The installer is required to ensure the installation meets all code requirements.
• examine these carefully as there will often be conflicts between the sprinkler piping, HVAC and plumbing piping
• Sometimes the mechanical will have sprinkler locations as per the mechanical engineer

19
Q
  1. Electrical Blueprints
A

• the control system, and the location of fixtures, switches, cable
trays, and etc. that may conflict with piping installations.
• the light locations and types will be found in the electrical
drawings and schedules. It’s important to know their locations to
avoid conflicts and obstructions.

20
Q
  1. Landscaping Blueprints
A

will detail fencing, finished
grade, trees to be planted, parking lots, etc.
• Refer to this drawing before installing hydrants, FDC, incoming
• Sometimes on the site plan, civil design

21
Q

Sprinkler system drawings

A
  • Sprinkler System Drawings
  • A sprinkler system is drawn according to building criteria and design requirements.
  • What criteria?
  • What design requirements?
  • Specs – legal documents
  • Take precedence
  • Only deviate with permission
  • Valuable info is summarized as notes
  • Know occupancy and type of building ABC review
  • Know water supply info
22
Q

Symbols

A
  • Blueprints use symbols to illustrate the equipment used on sprinkler systems, such as valves and hangers, as well as the different types of sprinklers in a sprinkler system
  • NFPA 170 Standard for Fire and Emergency Safety Symbols has created standard symbols that are used most of the time.
  • Go to 170
  • 1.2
  • Chapter 4
  • Chapter 7
23
Q

Sprinkler Equipment – Plan view

A
  • A sprinkler drawing indicates the placement of parts used in the operation or control of the sprinkler system
  • Sprinkler plan view - an aerial view of the basic layout of the sprinkler system
  • This is an important drawing to examine to determine if there may be obstruction issues with lights, other piping and HVAC.
  • Knowing the height (elevation) and the location at which project material and piping will be located, is critical.
24
Q

Sprinkler Equipment – Star measurement

A

• The star measurement, or elevation dimension box, indicates the vertical distance between the bottom side of the roof and the center of a pipe

25
Q

Sprinkler Equipment – Section views

A

• The sprinkler elevation or section view shows the placement of the sprinkler equipment in relation to obstructions, structural
members (such as an I-beam), finished ceilings, or other objects that cannot be easily shown on the plan view

26
Q

Sprinkler Equipment - Details

A

Detail view drawings indicate how sprinkler systems components
should be arranged, as well as the location for each component within the sprinkler system installation..
Code requirements are often detailed; the installer should know these, but they are also for other trades and the general to refer
to.
• Provides explanatory pictures for the installation crew

27
Q

Sprinkler Equipment - Risers

A

• A riser is a vertical section in a sprinkler system’s piping
• A riser measurement is normally shown using a 45º angle from the
main and branch lines

28
Q

The hydraulic calculated area is a cross hatch on drawing

A

• Hydraulic calculation nodes refer to the hydraulic calculations that relate to the flow and pressure loss requirements at specific
system locations (points).
• this is where calculation adjustments in the system happen.
• The number on the node will refer to a calculation and can be found in the calculation sheets.
• The area will relate to the calculation data table
• Go to fire protection drawing

29
Q

Design notes

A
  • note the publication of NFPA the system is designed to.

* Note the hazard classification of each area to determine the maximum spacing of the heads to be used
