History With Owner

• Ecova building

• Rock Pointe

• RiverView

– 5 Week install

• Davenport Series:

– Hall of Doges

– Tower

– Grand

Owner’s Goals• Large open area spaces

• High efficiency:

– Sound reduction between rooms

– Thermal envelope

• Reduced project schedule

• Reduced overall project cost

Accelerated Building Construction• Trusted partner with local support

• Repeatable prefabricated components

• Schedule driven project

• Weather/Temperature controlled environment

• Quality control

• Just in time shipping

Who Else Uses This Approach?

• Bridge builders

• Ship builders

• Airplane manufacturers

Project Approach:• Cast in place:

– Footings

– Shear walls

– Topping slabs

• Modular precast construction:

– Custom column and girder design for base floors

– Elevator and stair towers

– Hollow core decking

– Solid panel demising walls

– Insulated CarbonCast® wall panels

Cast in Place Footings• Transfer structural loads to the earth

• Anchored to rock for increased capacity

Cast in Place Shear Walls

• Transfer building lateral loads to footings

• Size dictates cast in place vs. precast

Precast Columns

• Structural columns to transfer loads from main floor to footings

• All columns cast and installed as single piece multistory members

• No splices required between pieces

Precast Floor Beams and Hollowcore Decking

• Prestressed flooring

• Large open spans

• Reduced weight/ft2

vs solid slabs

Precast Wall & Spandrel

• Rebar reinforced

• Prestressed wall panel

Precast Double-T Beams

• High capacity design – support HVAC and backup generator

• Allowed for open areas in ballroom (>100ft clear span) and kitchen (>60ft clear span)

Precast 3rd Floor Transfer Beams

• Transfer building vertical loads from hotel floors above to columns allowing large open areas in lower 2 floors.

• Utilized standard forms normally used for highway bridges.

3rd Floor Hollowcore and Topping

• Precast & prestressed deck

• Cast in place topping provides “composite” strength.

• Served as diaphragm to transfer lateral loads to shear walls for building stability.

3rd Floor Hollowcore and Topping

Precast Insulated Stair Tower Panels• Fire resistant, thermally

efficient stair well.

• Also used to provide lateral resistance for the structure.

Insulated Stair Wall Panels

• High thermal efficiency

• Carbon cast provides high strength composite design

Precast Demising Walls• Provided high level of sound dampening

between rooms and structural support of room levels

• Accommodated HVAC ductwork

• Doweled together for floor to floor continuity

Precast Demising Walls

Precast Exterior Wall Panels

• Pre-glazed

• Pre-painted

Precast Exterior Wall Panels

Precast Floor Slabs• (3) panels required to cover (2) rooms +

hallway

• Sized to reduce vibrations from walking (tested in the plant)

• Included shower pans and plumbing holes

• Welded to demising walls to provide instant diaphragm reducing bracing and increasing installation safety

Precast Floor Slabs

What to Watch For:

• Standardize panels to maximum extent

• Ensure detailed engineering is complete prior to production

• Solid communication between erector and production

• Plan for MEP upfront to allow for plant installed block outs and sleeves
