Sub-trades run their own submittal review before sending to the GC and design team. The review verifies the submittal against the contract documents - catching issues that would otherwise return Revise-and-Resubmit and delay procurement. Helonic enables systematic self-review at sub-trade affordability.

Sub-trade submittal economics

Sub-trades we work with described submittal cycles as a critical-path schedule risk. Each Revise-and-Resubmit cycle costs 14+ days. Sub-trades who self-review before submission avoid those cycles by catching issues at the source.

FAQs

Won't this duplicate the design team's review?

Both reviews check for compliance but at different stages. Self-review catches issues before they consume design-team time.

How long does typical self-review take?

Most submittals self-review in under 30 minutes - well worth the time vs. a 14-day Revise-and-Resubmit cycle.

What about for design-build sub-trades?

Particularly valuable for design-build because the sub-trade owns the design responsibility and submittals are higher-stakes.
