Essential Design Programs
with Accurate Sizing Calculations
help to “Streamline Your Design”
HVAC DESIGN SOLUTIONS
ENGINEERING SOFTWARE

 “Plumbing Design” from HVAC Design
Solutions is a package of software programs for
most of the Plumbing Designer’s sizing tasks:
 Fixture Unit/GPM Calcs
 Water System Sizing
 Waste & Vent System Sizing
 Roof Drain System Sizing
 Natural Gas System Sizing
 Water Heater Sizing
 Extensive Help Files, and “Extras”

 Reduce your dependence on Reference Books,
Charts, Graphs, and “Rules of Thumb”.
 Eliminate many of the usual Plumbing
Design Tasks
 Reduce common errors and mistakes
 Create an easy-to-follow, step-by-step
“Procedure for Plumbing Design” for all
projects.
Software Package contains most of
the sizing calculations and
procedures for typical projects

E Mechanical Coordination
F Plumbing Coordination
G Civil Engineering Coordination
H Electrical Coordination
1 Quickly review all Drawings in the Construction Document set, including Architectural,
Structural, Civil, Landscaping, Mechanical, Plumbing, Fire Protection, Electrical, Food
Service, and any other discipline. Spend not more than one minute per sheet, average.
2 Make a list of any apparent discrepancies or questions while reviewing the set, and add
‘flags’ to sheets where there are significant questions.
3 Quickly review the Specifications by reading through the Table of Contents for
Mechanical and Plumbing work. Check the Table of Contents against the actual
Specification sections to verify all sections have been included. Make a list of questions
that may come up during the cursory review.
4 Review Architectural Title Sheet, or first sheet in the set, and make a list of the Project
Square Footage, Building Occupancy Type, Building Construction Type, Governing
Codes, Index of Drawings, and any other information that relates to Mechanical or
Plumbing work.
5 Check for consistent appearance of Title Blocks, Drawing Scales, North Arrows,
Professional Stamps, Company Logos, Sheet Numbers, Sheet Titles, Issue Dates, and
Issue Revisions on all sheets.
B Demolition Plans
1 Verify that Demolition Symbols (cross-hatching, etc.) are clear and complete, and are
coordinated with other disciplines.
2 Verify there are notes regarding potential hazardous materials (asbestos, lead paint,
etc.), and coordinate with Architect or other Prime Consultant and Owner.

L Plumbing Detail Drawings
C Plumbing Underground Floor Plan Return to Table of Contents
1 Read all Sheet Notes and verify they are clear and appropriate.
2 Verify all References are correct. Follow references to indicated sheets.
3 Coordinate Plumbing Underground Plan with Structural Grade Plan. Verify that
below-slab Footings and Grade Beams have been shown on the Plumbing
Underground Floor Plan, for underground pipe coordination. (If Footings and Grade
Beams are not on Plumbing Underground Plan, they should be added to the
‘background’).
4 Verify that any pipes passing over, under, or through Footings or Grade Beams have
been coordinated with Structural Plans. Check on provisions for sleeving beams, etc.
Verify depth of Footings and Grade Beams below floor slab, to check for any
potential conflicts.
5 Verify that Footings and Grade Beams are not directly below Plumbing Fixture
outlets, Floor Drains, Floor Sinks, Plumbing Chases, or pipe drops, such as Storm
Drains and Overflow Drains. Verify coordination with pipes at Columns, such as
Sanitary Vents and Trap Primer water pipes, to avoid conflicts with Footings at
Columns.
6 Check for locations of building expansion joints or seismic joints, and verify that pipes
have been designed to accommodate expansion joints.
7 Follow all Waste Pipe risers up to floors above. Place a pencil check-mark on each
riser as it is verified to continue on the floor above (or roof). Check for coordinated
locations from floor to floor on each pipe riser.
8 After following each Waste pipe riser to the top, follow horizontally to the most remote
fixture or drain connection point. Pencil in Fixture Units (FU) for all Fixtures and
Drains served by each Waste riser. Sum the flow rates (FU) from the remote fixtures
or drains, back to the risers. Pencil in the accumulated FU on the plans adjacent to
the pipes. Verify that Fixture Units are listed for all fixtures or drains and that
Schedules for each fixture are complete.
9 If the Floor Plan has references to larger scale plans (such as Enlarged Toilet Room
Partial Plans), follow to the referenced Enlarged Plan. Verify all pipe sizes are
coordinated from Floor Plan to Enlarged Partial Plan. Verify the Floor Plan and
Enlarged Plan have the same background and are current with the latest
Architectural plans. Pencil in the Fixture Unit value for each Fixture or Drain on the
Enlarged Plan, and sum the FU to the extent of the Enlarged Scale Plan. Transfer
the total flow rates back to the original Floor Plan, for continuation.
