Benefits Relative Cost
  • CUSTOMER BENEFITS
  • All the benefits of precast
  • Up to 66 lighter
  • Less concrete
  • Larger pieces
  • Reduced shipping
  • Reduced erection time or crane size
  • Ideal for use with a tower crane where capacities
    are limited
  • Ideal for mid-and high-rise buildings or sites
    with poor soils
  • Non-corrosive face reinforcing
  • Ideal for salt-laden environments
  • High Thermal Efficiency
  • Composite R-values ranging from R-8 to R-12
  • Superior mold resistance
  • RELATIVE COST
  • Installed cost of panels is same as -- or less
    than conventional precast
  • Superstructure and foundation costs are usually
    less
  • Insulation and/or HVAC costs can also be reduced

Benefits Relative Cost
  • PRECASTER BENEFITS
  • Can cost less to provide
  • Less concrete
  • Larger pieces
  • Reduced shipping
  • Reduced erection time or crane size
  • Ideal for use with a tower crane where capacities
    are limited
  • Ideal for mid-and high-rise buildings or sites
    with poor soils
  • Unique, specifiable, proprietary
  • Something new to talk about
  • Gets you first and last look
  • Hard to displace once its designed in
  • Alternatives are less desirable
  • Brick leaks, EIFS has problems, GFRC is not
    readily available and SlenderWall-like systems do
    not offer the same appearance or insulation
  • Can be combined with conventional precast to
    value-engineer a job
  • Precast spandrels on lower-story parking
  • CarbonCast panels on upper stories

Full-Scale Load Test

49
Test Procedure
  • Loading Protocol
  • 50 of designed wind in each direction 300
    cycles
  • 85 of design wind load sustained for one hour in
    each direction
  • Incrementally loaded to failure

This type of testing has never been done on an
insulated sandwich wall before!
50
Test Results
Testing showed that the CarbonCast insulated wall
panel is 100 composite!
  • What does this mean?
  • AltusGroup can make thinner panels because both
    wythes work together
  • AltusGroup can span longer with thinner panels
  • Panels are thermally efficient
  • AltusGroup can supply panels with extremely high
    R-Values

Thermal Performance
  • 1. AltusGroup insulated wall panel is as
    thermally efficient as any wall system in the
    market place.
  • We use Expanded Polystyrene (EPS)
  • Extruded Polystyrene (XPS) can be used but costs
    more

54
R-Values
55
AltusGroup vs. Competition
Lets Use a Sample Project to Compare AltusGroup
Panels with the DOW or Owens Corning Systems
  • Case Study Project Parameters
  • Height of building is 32 ft with roof tie point
    at 2 ft. from top of panel
  • Load bearing for steel roof with bar joist span
    of 60 ft.
  • R- Value required for this project is 13 --
    steady state

56
AltusGroup vs. Competition
  • The AltusGroup Panel would be our Standard 8
    panel
  • The Dow or Owens Corning Panel as non-composite
    panel would have a 2 outside wythe, 2.5 of
    insulation, and depending on the engineer, a 5
    to 8 inside wythe

57
AltusGroup vs. Competition
  • Assume Costs
  • Concrete 0.30/inch/ sq. ft.
  • EPS insulation 0.12/in/sq.ft.
  • Shear grid 0.32/sq.ft. wall surface
  • Owens Corning system (w/ pins) 1.40/sq.ft. of
    wall surface
  • DOW System (w/ non-composite pins) 1.40/sq.ft.
    of wall surface

58
AltusGroup vs. Competition
  • AltusGroup Panel
  • Concrete cost 0.30 x 4.67 1.41
  • Insulation cost .12 x 3.33 0.40
  • Shear Grid cost 0.32
  • Total cost of material 2.13

59
AltusGroup vs. Competition
DOW Panel Concrete cost 0.30 x 7
2.10 Insulation cost 0.12 x 3.33

AltusGroup vs. Competition
Comparison of Panel Weights AltusGroup panel
weighs 59 psf (22,700 lbs for a 12 wide x 32
tall panel) DOW or Owens Corning panel weighs
87.5 psf (33,600 lbs for a 12 wide x 32 tall
panel)

Conclusions
  • High R-values for less cost
  • 2 hour design
  • Lighter weight panels
  • 100 composite action leads to thinner panels,
    reduced construction costs, and more net rentable
    or usable floor area
  • Horizontally-spanning hardwall panels can
    eliminate column-to-column foundations on
    pre-engineered buildings
