Tilt-Up FeasibilityFeasibility 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
companies with concrete tilt-wall experience?
X

COST $376,200 $438,900
MATERIAL Affordable in TN Early delivery charge
ERECTION Fewer panels More panels, More time
LEAD TIME Cast on-site, possible weather impacts
5-8 Weeks
TRANSPORTATION Cast on site, no cost Delivery from plant to site
CONSTRUCTABILITY Extra planning Very Similar
QUALITY Potential Repairs Better, due mainly to the controlled environment

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
