FAQ
Questions Rebar Estimator owners ask.
- 01
What structural elements are supported?
The server supports standard elements including beams, columns, slabs, and footings via the get_element_type_details capability.
- 02
How is the total weight calculated?
Total weight is calculated by determining the effective length of bars (subtracting concrete cover), adding required lap lengths, and applying the steel density constant.
- 03
Can I include a waste factor in my estimate?
Yes, all calculation capabilities allow for an optional wasteFactor to account for cutting losses and site handling.
