For fabricators

It is a fair objection and it is usually true. It is worth being precise about why, because the reason is not that the detailers were bad.

Rework is produced by unanswered questions, not by bad drafting

Almost every expensive detailing error starts as a decision the detailer had to make because nobody else would: a bolt grade nobody confirmed, a camber nobody specified, an edge distance at a skewed connection that the design drawings did not resolve. Someone a long way from the job takes that decision quietly, consistently, forty times, and it arrives in your shop as material that has already been cut.

The second source is the model nobody checked on arrival — wrong origin, wrong revision, properties missing that the next stage needed. That one is discovered late by definition, because everything built on top of it looks correct.

What we do differently about both

Questions are raised against the drawing rather than resolved silently, and the answer goes into the model so the same question cannot be answered two ways on two sheets. An incoming-model check covers origin, units, grid and level agreement, and whether the contents match the issue sheet; it is written down and sent back. Connection design and detailing run in the same model rather than across two parties, so a connection change is a model change rather than a markup.

That is the whole of it. It is process, not a trick, and it is published in full at how we work so you can hold us to it.

What we cannot show you

No rework rate. Seimora is a new brand with no completed projects published under its name, and a rework figure from a firm with no published portfolio is a number you would be right to ignore. We are not going to invent one.

What we can do instead is make the first scope small enough to check: one sequence, one lot, one connection type — priced and delivered before you commit the rest of the job to it. Your own checking is better evidence than our claim.

What we work in

Tekla Structures, SDS2 and Advance Steel, against AISC 360, AISC 303, AWS D1.1, EN 1090-2, Eurocode 3 and IS 800 depending on where the steel is erected. The full list is on standards. If your shop standard is a template, a marking convention and a set of drawing preferences, send them — working to yours is cheaper for both of us than teaching you ours.
