System Layout Flashcards
Fire Protection Drawings
- Specifications
- Details
- Layout
- Quantities
- Sprinklers
- Fire extinguishers
- Hydraulic data
Specifications
- The written instructions for a construction project
- Legal and insurance requirements.
- Types of material
- Who supplies equipment or material – lifts, extinguishers, pumps
- Who performs specific work – coring, fire stopping
- Quality of workmanship. – inspections, warranties
- Methods of installation – ladder usage, lifts
- When shop drawings are supplied – fire pump, extinguisher cabinets
- Test requirements – per NFPA
- Environmental conditions maintained during construction - LEEDS
- Allowances for future needs – pipe sized/installed for additions
Specifications are Legal Documents in writing
• Take precedence over blueprints
• Only deviate with written permission from owner
• Ensure you understand the specifications
• Specifications can be 100’s of pages or notes on the
blueprints
• Valuable info: often summarized as Notes: on the drawings, read them thoroughly
CSI – Construction Specifications Institute Format (Started in 1963)
- Introductory information, is an overview of the information
that will be covered by the project specifications
• table of contents, Schedules, certifications, - Bidding requirements include information about:
• who is qualified to bid
• bidding instructions
• conditions for awarding the bid
• bid scopes
• Tender/bid (basically the same meaning) deposits
• pre-bid meeting schedules - Contracting Requirements
• Agreement form
• bonds, insurance
• Safety
• Changes
• all the requirements - General Requirements
• Payments
• Administration
• Quality
• Facilities and Spaces/Systems and Assemblies
• Items specific to the job - Construction Products and Activities
• Numbered 1 though 16
• The numbers cover the phases/disciplines of the project
• This category contains the project specifications
Mechanical
- 15 is typically Mechanical
- The 300 section could be further broken down
- General – scope of work
- Materials – pipe schd’s, sprinkler styles…
- Execution – coring, fire stopping…
- Great in theory doesn’t always happen
Specifications can come in different formats
• 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
• Added more divisions
• when the sprinkler contractor isn’t ‘subbed’ under mechanical it
would often be in Division 21
Alberta Construction Tendering System
• Helps owners, consultants and contractors to develop a unified
system
• Projects are listed within the association
• Protects all parties involved
• Used for larger projects and municipal/government jobs
Bidding Process
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
The Estimator
• Read and interpret specifications properly it requires
training and experience
• Read all the specs
• Know the scope of work
• Underground, alarms, pumps, water supplies…
• Clarify any questions
• 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
Once awarded
• 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
Blueprint Reading
• 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
General Notes
• 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
Divisions of Blueprints
- 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
Site Plans
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.
Foundation plan, Floor plan, Elevations, Section Drawings
• 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’
