To get a machine foundation right first time, build it to the final vendor drawing, cross-check civil, steel and equipment drawings, set anchor bolts with templates and record their positions, use the right concrete with proper compaction and curing, and grout only after the equipment is aligned. One team for foundation and erection avoids disputes.
1. Use the final vendor drawing
Foundations must be built to the final, approved drawing from the equipment vendor, not a preliminary one. Confirm the revision before work starts.
2. Check civil, steel and equipment drawings together
Bolt positions, pockets, levels and connected structures should be cross-checked before the pour.
3. Set anchor bolts with templates
Templates hold bolts in exact position and projection during concreting. Record co-ordinates and levels before and after the pour.
4. Concrete, compaction and curing
The right mix, proper compaction and enough curing time give the strength the machine needs, especially for vibrating equipment.
5. Align, then grout
Equipment is set, levelled and aligned, then grouted. Grouting before alignment is final causes problems.
6. One team from foundation to erection
When the same team builds the foundation and erects the equipment, there is no argument about whose mistake it is.
