What Acceleration Actually Means for Detailing
Accelerated detailing means either more resources on the same scope (additional modelers, extended hours) or phased releases that allow fabrication to begin on early packages while later packages are still being detailed. Both strategies work — but both have costs. Additional resources increase the fee; phased releases require precise coordination to ensure connection compatibility between packages.
The Limits of Schedule Compression
Detailing has irreducible minimums. The model must be built before drawings can be extracted. QA/QC must be performed before submittal. The EOR review cycle is outside the detailer's control entirely. The compressible phases are: model build time (with more resources), internal QA (with more reviewers), and the time between completion and submittal (essentially zero). What cannot be compressed: EOR review and approval, which typically floors at 5 business days and practically runs 10–14.
How Tectonix Supports Accelerated Schedules
Tectonix's two-shift production model is specifically designed to support accelerated timelines. When U.S. business hours end, organized work packages move into the next production cycle. The following morning, the U.S. project manager reviews output, confirms quality, and identifies the next day's priorities. On a standard commercial project, this model compresses the detailing phase by 25–40% compared to single-shift production. Phased releases can be planned as early as the kickoff call.
Phased Release Planning for Fast-Track Projects
The most effective acceleration tool for fabricators with a firm erection start date is a phased release plan agreed at kickoff — not improvised two weeks before the crane arrives. The plan should define: which members are in Phase 1 (typically anchor bolts, base plates, and early-erection-zone primary columns), what drawings are required for that release, and the specific date by which Phase 1 must be available to the shop. When the detailer knows the Phase 1 release date before modeling starts, they sequence their work to reach that milestone even if later phases are still incomplete. This requires the fabricator to communicate the erection plan, not just the project end date.
- Phase 1: Anchor bolt plans — issue within 1–2 weeks of model start
- Phase 2: Primary columns and base plates — issue before mill order deadline for heavy sections
- Phase 3: Primary framing by erection zone — timed to shop production capacity for first erection zone
- Phase 4: Secondary framing — released as primary framing is cleared from the shop floor
- Phase 5: Miscellaneous steel — stairs, handrails, embeds — released on parallel track
Connection Design on an Accelerated Schedule
The most significant schedule risk on fast-track projects is unresolved connection design. If the EOR has not provided connection loads or has not confirmed delegated design responsibility before modeling starts, the detailer will RFI every non-standard connection — and those RFIs are not acceleratable. The solution is to resolve connection design responsibility on day one. For projects with delegated design, engage a connection PE before kickoff, not after the first connection question arises. A PE who is on call during the modeling phase can turn connection calculations in 24–48 hours; one engaged mid-project may take 2–3 weeks to mobilize and review the accumulated backlog.
Managing EOR Review on an Accelerated Schedule
The EOR's review cycle is the most consistent schedule constraint on any accelerated project — and the one most often underestimated in fabricator schedules. The EOR's contract typically allows 10–14 business days per review cycle, and that timeline is independent of the fabricator's urgency. On fast-track projects, engage the EOR early about schedule: request a pre-submittal coordination call to resolve the highest-risk items before the formal submittal, which can reduce the number of comments and shorten the review cycle. Some EORs will agree to a staged review — reviewing anchor bolt drawings in 5 days before the full structural package is complete — when the request is made early and the value is clear.
Cost of Acceleration and How to Price It
Schedule acceleration costs money — and that cost should be built into the detailing contract, not discovered through change orders. Acceleration costs include: premium for additional modelers added to the team, overtime or extended production hours, expedited QA turnaround with additional reviewers, and the project management overhead of coordinating phased releases and multiple simultaneous work streams. When requesting an accelerated schedule from a detailing firm, ask specifically: 'What is the premium for delivering Phase 1 in two weeks instead of four?' A firm that cannot price this is not operationally equipped to deliver it.
