The Real Cost of Getting Steel Detailing Wrong

The Real Cost of Getting Steel Detailing Wrong

All fabrication projects have zero tolerance for shop drawings errors. Even a minute mistake in your structural steel fabrication drawing, as minute as a missed weld symbol or an incorrect hole location or a mismatched connection-load needs, can sometimes bring the entire shop floor to a standstill.

Skills gap in your team, incomplete or discrepancies in engineering drawings, coordination failures are some challenges daunting fabrication shops. And the shop ends up spending more time in rework than in fabrication, reducing profit margins and missed deadlines.

In Enphy’s 12+ years of experience as a trusted steel detailing company, we have seen these problems repetitively for fabricators across the USA, Canada, UK, Australia, and New Zealand.

Our steel detailing solutions help overcome these challenges by working as an extension of your in-house team or independently – tailored to your setup. We study your drawings, raise RFIs for missing information before beginning detailing, and deliver shop drawings for structural steel to leave no room for guesswork for your foreman on the floor.

What Our Clients Say

★★★★★

"We engaged Enphy to support detailing on a 900-ton commercial project during a peak workload period. Their team integrated smoothly with our project managers, raised RFIs early, and delivered coordinated shop drawings that our shop could release directly to production. The NC files were clean, and we did not experience fabrication stoppages related to detailing. We continue to use them as an extension of our in-house team."

Frequently Asked Questions

What is the difference between a structural steel shop drawing and a fabrication drawing?

Structural steel shop drawings communicate how the structure is built piece by piece. These are essentially a set of erection drawings, anchor bolt plans and assembly drawings. On the other hand, fabrication drawings are slightly more detailed – a detail drawing of every single member depicting dimensions, hole locations, weld specs and cutting instructions. This why fabrication drawings are sometimes also called piece drawings. Enphy delivers both under one coordinated package, so nothing falls through the gap between design intent and the shop floor.

Which international standards does Enphy work to?

Enphy teams are qualified and equipped to deliver steel detailing drawings that are compliant with region specific standards such as AISC in the US, CISC in Canada, BS EN 1993 / Eurocode 3 across the UK and Europe, AS 4100 in Australia, and NZS 3404 in New Zealand. If you need anything apart from these, our team is willing to go extra mile and deliver your needs.

How long does it take to receive shop drawings for structural steel?

Turnaround depends on several factors such as the scope of work, types of steel connection and how precise and error-free are your inputs. Ideally, to prepare steel detailing drawings for standard structural frames that are free of any major coordination issues, we typically take 7-10 business days from the time you sign off the projects of standard structural frames.

How is pricing structured for steel detailing outsourcing?

We charge a lump-sum amount for all our projects based on the review of your contract drawings, giving you complete control and visibility into project costs across the lifecycle. Our customers have reported minimum 40% of cost savings and as high as 60%, compared in-house detailing.

Can Enphy work alongside our in-house detailing team?

Yes — and this is one of the most common ways in which we engage. As a trusted steel detailing firm with 12+ years of experience, we work hand-in-hand with your in-house detailers, taking on overflow work, specific trade packages, or full project scope. We loop in your project manager through whichever collaboration tools your team already runs on.

Do you handle complex or specialist steel structures?

Yes. We have successfully delivered several steel detailing projects for petrochemical refineries, power plants, bridges, trusses, high-rise buildings, industrial platforms, and water treatment plants. Our detailers’ domain-specific expertise empowers us to confidently deliver steel detailing for complex structures with custom connections and challenging geometry.
