The RFI That Kills Commercial Steel Projects — And How to Prevent It

Most RFIs are noise. A clarification on a dimension, a material substitution question, a spec interpretation that takes an afternoon to resolve. Annoying, but manageable. Then there's the other kind — the RFI that stops your project cold. The one where the anchor bolt pattern embedded in the foundation doesn't match the column base plate. Where the EOR's connection calculations use a standard that conflicts with what the detailer designed. Where the joist bearing seat depth doesn't work with the beam flange width at a non-standard framing condition that nobody caught until steel was on the truck. These aren't communication problems. They're coordination failures that originated in the detailing phase — and they're almost entirely preventable if the detailer is doing the right work in the first two weeks of a project. Here's what that work looks like, and why most detailers — especially offshore shops without a single project owner — aren't doing it.

What Makes a Routine RFI Turn Fatal

Every project has RFIs. The ones that matter aren't the ones with the highest question count — they're the ones that hit the critical path at the worst possible moment.

A fatal RFI has a specific anatomy. It involves a conflict between two design decisions made independently by two parties who assumed the other was handling coordination. By the time it surfaces as an RFI, something downstream has already been committed: concrete has been poured, material has been cut, or an erection sequence has been locked. The RFI isn't a question anymore. It's damage control.

The common thread across every project-stopping steel RFI is the same: the detailing phase failed to surface the conflict while it was still cheap to resolve. That's not always the detailer's fault — incomplete IFC documents, missing civil coordination, late EOR calc packages — but it's always the detailer's job to flag it before it becomes someone else's emergency.

The Three RFI Types That Stop Commercial Steel Projects

1. Connection Standard Conflicts

This is the most technically complex fatal RFI, and the one that most often gets blamed on the wrong party. The EOR produces a connection design in their structural calculations — moment connections, shear tab standards, HSS brace connections — based on AISC 360, their own firm's standard details, or a project-specific connection design package. The detailer works from those same documents but interprets the design intent differently, or fills gaps using their own standard assumptions.

The conflict usually lives in the details: weld size on a moment end plate, bolt gauge on a shear tab to an HSS column, cope geometry at a coped beam bearing. In Tekla, the model looks clean. The connection resolves. It's only when the fabricator submits and the EOR reviews that the discrepancy surfaces — and by then the shop may already be two weeks into fabrication.

The fix isn't a better RFI process. It's a pre-submittal connection design review where the detailer cross-references their modeled connections against the EOR's calc package before the first IFC submittal goes out. Not after comments come back. Before.

2. Anchor Bolt Plan / Foundation Coordination Gaps

This is the one that actually stops projects cold. Anchor bolts are set in concrete. Once they're poured, they're permanent. If the anchor bolt plan the detailer worked from doesn't match the foundation drawings the civil engineer produced — or if the civil drawings were revised after the anchor bolt plan was issued and no one updated the steel model — you're looking at field corrections, sleeve additions, or structural repairs that can run weeks and tens of thousands of dollars.

The failure mode is almost always the same: the structural detailer and the civil/foundation engineer are working from different document revisions, with no formal cross-check between disciplines before concrete is placed. On projects where the steel detailer has no direct line to the EOR or the civil, this gap can go undetected through multiple submittals.

Column base plate geometry — bolt circle diameter, anchor bolt projection, sleeve sizing for seismic SDC requirements — has to be verified against the current foundation drawing revision before any field work touches that foundation. This is a two-hour coordination task in the first week of detailing. It's a two-week schedule event if it's discovered after the pour.

3. Joist and Deck Interface at Non-Standard Framing Conditions

SJI standard joist end conditions assume a standard bearing seat depth. Standard deck profiles assume standard joist spacing and framing geometry. Commercial projects routinely have neither. Sloped roof framing, variable joist spacing, beams with large top flange variations, or girders with non-standard flange widths create conditions that the standard details don't cover — and those are exactly the conditions where the joist bearing seat, the deck attachment, and the structural framing have to be coordinated explicitly.

When they're not, you get an RFI at steel erection. The joist seat depth doesn't give adequate bearing on the flange. The deck can't span the modified panel width. A horizontal bridging conflict forces a field modification. At best, you're losing a day on the erection schedule. At worst, you're waiting on an EOR revision while the crew stands by.

Why These Coordination Failures Keep Happening

The root cause isn't complexity — these are solvable problems. The root cause is how most detailing engagements are structured.

When a fabricator hires an offshore detailing shop, or a domestic shop running multiple concurrent projects, there's often no single person who owns the design intent of that project from kickoff to submittal. The model gets built from whatever documents are in the package on day one. Pre-submittal coordination calls with the EOR don't happen because nobody's explicitly responsible for scheduling them. The civil foundation drawings aren't cross-checked against the anchor bolt plan because the detailer assumed the GC was handling that coordination.

Offshore shops compound this problem structurally. A question that surfaces at 3 PM on a Friday in NC doesn't get answered until Monday — if the question gets asked at all. Without a single named contact who has read the project spec, reviewed the EOR's calc package, and can get the EOR on the phone, these conflicts don't get surfaced. They get buried in the model.

Early Detection: What the First Two Weeks Should Look Like

A detailer doing this right isn't waiting for the IFC submittal to find conflicts. The first two weeks of a structural steel detailing engagement are the highest-leverage period of the entire project.

Here's what that work looks like in practice:

3D model clash detection against structural and architectural documents. Running the Tekla model against the current architectural and MEP backgrounds early identifies physical conflicts before they propagate through the fabrication package. A beam elevation conflict that's caught in week two is a model revision. Caught after fabrication, it's a field cut.

Connection design review against the EOR's calc package. Every connection type in the model — moment frames, brace connections, shear tabs to HSS, base plates — gets cross-referenced against the EOR's stated design intent. Discrepancies get logged and sent to the EOR for clarification before submittal, not after.

Anchor bolt plan cross-check against civil foundation drawings. Current revision of both documents. Every column location. Bolt circle, projection, sleeve spec, base plate dimensions. If there's a discrepancy, it goes to the EOR and civil engineer immediately — while the foundation schedule still has room to respond.

Non-standard framing condition documentation. Every joist bearing condition that deviates from SJI standard. Every deck panel with non-standard geometry. These get flagged and resolved against the structural drawings before the joist and deck package goes out for pricing.

This is coordination work, not modeling work. It requires someone who can read the EOR's calc package, understand what questions need to be asked, and has a direct line to the people who can answer them.

The Cost of Late Detection

Put concrete numbers to what these RFIs actually cost when they're caught late.

An anchor bolt pattern mismatch discovered after foundation pour: field correction with sleeve-and-epoxy anchoring runs $8,000–$25,000 in direct cost depending on column load, plus two to four weeks of schedule impact on the steel erection sequence.

A connection standard conflict caught at EOR final review: redetailing and refabricating the affected connections — shear tabs, end plates, column stiffeners — at the fabricator's shop can represent 10–15% of the original fabrication cost on the affected framing, plus submittal re-review delay.

A joist bearing conflict caught at erection: crew standby while the EOR issues a revised detail runs $15,000–$30,000 per day in combined erection and general contractor overhead. A two-day delay on a commercial project is a conservative estimate.

None of these costs show up on the detailer's invoice. They show up on yours.

Three Questions to Ask Your Detailer About RFI Prevention

Before you award a steel detailing package, ask these:

1. "What's your process for coordinating with the EOR before the first IFC submittal?" A detailer without a clear answer to this question is planning to find problems through the submittal review cycle — on your schedule.

2. "Who cross-checks the anchor bolt plan against civil foundation drawings, and when does that happen?" If the answer is "we work from whatever's in the package," that coordination isn't happening.

3. "How do you handle non-standard joist bearing conditions?" A senior detailer should be able to describe their process for flagging and resolving SJI deviations before the joist package is priced.

The answers tell you whether you're hiring a detailer who's building the model, or a detailer who's managing the coordination.

NRSteel's Pre-Submittal Process Is Built Around This Problem

NRSteel works exclusively with steel fabricators on commercial and institutional structural projects. Our pre-submittal coordination process is specifically designed to surface the three conflict types described above — connection standard gaps, anchor bolt plan discrepancies, and non-standard framing conditions — before they reach the field, the EOR's review comments, or your schedule.

Every project has one named contact, NC-based, same timezone, reachable by phone. When a question needs to go to the EOR on a Friday afternoon, it gets asked on Friday afternoon.

If you're evaluating detailing partners for your next commercial steel project, contact NRSteel for a scope review. We'll walk through your project documents and identify the coordination gaps before detailing starts.
