Foundation Bolt Template and Setting-Out Checklist
Quick Summary
A correct foundation bolt is not enough if it is set out incorrectly. Check approved coordinates, template fit, projection, embedment and associated hardware before dispatch and placement.
Table of Contents
The foundation bolt can meet its steel specification and still miss the base-plate holes. Setting-out is a coordination problem between civil drawings, equipment drawings and fabrication.
Use one approved drawing set
Confirm equipment tag, base-plate revision, foundation revision, anchor coordinates and elevation. When drawings disagree, resolve the interface before the bolts or template are made. Mark the approved revision on the RFQ so a previous layout cannot silently enter production.
Check the template as a manufactured part
A template should position the anchors at the intended spacing and orientation while the concrete is placed. Verify hole pattern, bolt fit, datum marks and how the template will be held. Ask who supplies the template and whether it is included in the same packing set as nuts and washers.
Projection and embedment are linked
The thread available above the finished concrete has to work with grout thickness, base plate, washers and nuts. The required embedment below is part of the structural design. Do not shorten a bolt in the field or alter bend geometry without project approval; capacity cannot be inferred from steel grade alone.
Inspect before dispatch and placement
Check overall length, thread length, material identification, anchor spacing in the template and label each set by equipment tag. At site, recheck orientation and elevation before concrete placement. Record deviations and obtain designer disposition instead of forcing the base plate to fit.
A practical example
An EPC team can receive anchors made to the correct drawing but still face installation delay when the setting template is based on an older base-plate revision. Before fabrication, reconcile the equipment tag, bolt coordinates, plate holes and concrete datum on one controlled issue. Mark that revision on the template and packing list so the site team can verify the set before placement.
Before you send the enquiry
Use this short check before you ask for price or delivery. It keeps the quotation tied to your actual engineering requirement.
- Approved foundation and base-plate drawings
- J, L, straight or custom anchor pattern
- Diameter, pitch, length and projection
- Material grade and coating
- Nut, washer, sleeve and template
- Anchor coordinates and tolerances
- Quantity, tags, documents and destination

Frequently Asked Questions
Who approves foundation bolt embedment?+
The project structural or civil engineer must design and approve the complete anchor system.
Should the template be ordered with the bolts?+
If required by the installation plan, include its approved drawing and quantity in the same RFQ.
