Current through Reg. 50, No. 138; July 16, 2024
(1)
				Plumbing Systems are those systems within or adjacent to a building that convey
				fluids and gases in connection with sanitary drainage, storm drainage,
				specialty drainage, venting, water supply, water heating, vacuum, and
				compressed gases for medical and non-medical applications. Items to be
				considered in the design and analysis of plumbing systems are, as applicable to
				the particular project: load characteristics and capacities; distribution of
				fluids; pressure drop; instrumentation and control; performance requirements;
				and installation requirements.
(2)
				The Plumbing System(s) shall be based on and shall reference the Florida
				Building Code, the Florida Fire Prevention Code, applicable standards (such as
				ASHRAE, ASME, ASPE, ASSE, ANSI, NFPA, etc.); or on if no other such standards
				are available alternative engineering sources and good engineering
				practice.
(3) For Mechanical
				Engineering Documents pertaining to Plumbing Systems exempted by the threshold
				requirements for mandatory use of professional engineering services established
				by Section 471.003(2)(h),
				F.S., the Engineer of Record shall determine the level of detail shown on plans
				for a plumbing system. All such plans shall include a disclaimer stating the
				Plumbing systems are exempt from professional engineering services and shall
				provide a clear understanding of the minimum system requirements expected to be
				installed by the contractor and permitted by the authority having jurisdiction
				(AHJ). In the event the Engineer of Record provides more information and
				direction than its minimally required, he or she shall be held responsible for
				the technical accuracy of the work in accordance with applicable codes,
				standards, and sound engineering principles.
(4) Mechanical Engineering Documents
				pertaining to Plumbing Systems that exceed the threshold requirements for
				mandatory use of professional engineers services must include the following
				information, if applicable to the particular project:
(a) Demonstrate and provide adequate
				information for the AHJ to determine compliance with codes and ordinances.
				These may include test methods and results or data and tabulations that are
				results of the design.
(b)
				Equipment selection schedules for each piece of plumbing equipment. All
				equipment must include the following information, if applicable to the
				particular equipment:
1. Equipment
				efficiencies.
2. Electrical
				requirements based on voltage and phase.
3. Fuel requirements.
4. Fixture flow or flushing rates.
5. Fluid flow and pressure head
				quantities.
6. Heat transfer
				capacities.
7. Motor sizes and
				quantities.
8. Tank capacities for
				storage, expansion, or compression.
9. Interceptor and separator
				capacities.
(c) Floor
				plans, site plans, and building and plumbing system sections or elevations as
				appropriate to provide the minimum system requirements expected to be installed
				by the contractor.
(d) Isometric or
				riser diagram with pipe sizes as follows:
1.
				Potable water.
2. Sanitary and
				vent.
3. Storm water.
4. Other fluids and
				gases.
(e) Piping layouts
				and sizing; and insulation requirements.
(f) Total or cumulative plumbing capacities
				as follows, either listed on the isometric or riser diagrams or in table form
				on the plans.
1. Total water supply fixture
				units and coincidental flow rate in gallons per minute.
2. Total drainage fixture units.
3. Cumulative area in square feet and
				coincidental flow rate in gallons per minute for each roof drain or storm
				drain. Total flow rate in gallons per minute for each storm water conductor
				discharging from the building.
(g) Design data for septic tank drain field
				sizing, when applicable.
(h)
				Portable water system design for minimizing bacteria growth (Legionella), based
				on heat, chemicals, or other means.
(i) Domestic hot water system design to
				prevent scalding, when applicable. Designs shall include, but not be limited
				to:
1. Design temperatures.
2. Temperature monitoring points necessary to
				confirm temperatures throughout the system.
3. Mixing valves or temperature-limiting
				devices.
(j) Design shall
				be in accordance with requirements for accessibility by individuals with
				disabilities adopted by the authority having jurisdiction.
(k) Unless included on HVAC system plans,
				design for fuel gas system, including piping layout and sizes; isometric or
				riser diagram with pipe sizes; and fuel gas capacity and pressure for each pipe
				section.
(l) Instrumentation and
				Control requirements, unless included on either Electrical or on
				Instrumentation and Control.
(m)
				Identify and locate plumbing fixtures, valves, pumps, tanks, accessories,
				specialties, enclosures, and such equipment.
(n) Materials for all plumbing systems shall
				be specified.
(o) All data needed
				to complete the calculations for compliance with Florida Building Code, Energy
				Conservation as applicable.
(p) A
				list, description, or details of through-penetration firestop systems as
				applicable.
(q) System
				commissioning requirements for demonstrating compliance with the Florida
				Building Code, Energy Conservation.
