Tilt-up vs. Precast Existing Wall Systems Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Background – Stages of Tilt-up 1 2 3 Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Tilt-up Activity Sequencing 1. Mass excavation 2. Subgrade Preparation 3. Install footings and foundations 4. Install any underslab MEP work 5. Form, reinforce, pour, & cure floor slabs 6. Form & pour tilt-up walls 7. Insert leveling pads on perimeter footings 8. Set tilt-up walls with bracing 9. Grout in-between panels and footings 10. Steel erection 11. Erect insulated metal wall panels 12. Install Roofing and sheet metal 13. Remove wall bracing Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Tilt-Wall Composition Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Heat Transfer R-Value Concrete Walls 10 5” Metal Insulated 40 Panels Equation: q x = (T ∞ 1 - T ∞ 2 ) * A / Total R-Value Determination = Concentrate mainly on: Cost � Schedule � Constructability � Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Tilt-Up Feasibility Feasibility Questionnaire for Tilt-up Wall Panels Yes No Are the exterior panel surfaces basically flat? X Is the site relatively flat or is there sufficient floor area available as a casting surface? X Will the majority of the panels be under 30ft. in height? X Will these walls represent over 50% of the total building wall surface? X Are these tilt-up wall panels going to rest on the foundation? X Will the weight of the panels fall within the crane capacity limits? X Will the panels be designed with a basically repeatable pattern? X Is this a common construction method in the local area and are there any construction X companies with concrete tilt-wall experience?

FDA / Special Considerations � Finishes : ~Floors ~Walls ~Pipes ~Trench Drains High Traffic Areas Doors Cold Climate Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
Conclusions � Utilize Long Distance Procurement Tools � Tilt-up Walls vs. Precast Walls ~Close Call ~Tilt-up is a good alternative ~Precast has better quality & Less Repairs Associated ~I would Pick Precast Importance of FDA / Special Considerations � Todd McCaskey Spring 2006 Senior Thesis Construction Management Penn State University
