– 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
![Page 13: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/13.jpg)
Cast in Place Shear Walls
• Transfer building lateral loads to footings
• Size dictates cast in place vs. precast
![Page 14: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/14.jpg)
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
![Page 15: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/15.jpg)
Precast Floor Beams and Hollowcore Decking
• Prestressed flooring
• Large open spans
• Reduced weight/ft2
vs solid slabs
![Page 16: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/16.jpg)
Precast Wall & Spandrel
• Rebar reinforced
• Prestressed wall panel
![Page 17: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/17.jpg)
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)
![Page 18: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/18.jpg)
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.
![Page 19: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/19.jpg)
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.

Precast Insulated Stair Tower Panels• Fire resistant, thermally
efficient stair well.
• Also used to provide lateral resistance for the structure.
![Page 22: Oldcastle Precast Spokane - Urban Modular Construction - The Grand Hotel](https://reader030.vdocument.in/reader030/viewer/2022020214/58819c911a28ab1a398b4643/html5/thumbnails/22.jpg)
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 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

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
