GC Milestone Review That Gets a Voice Into the Design Process
Find issues at milestones, when there's still time for design revision. Not at IFC, when revisions cost real money.
GCs increasingly participate in design milestone reviews - sometimes formally as CMAR or DB partners, sometimes informally as preferred-bidder relationships. The earlier the GC voice enters the design process, the more impact it has. Helonic enables GCs to bring substantive feedback to milestone reviews without staffing a senior preconstruction engineer to read every set.
The economics of early GC voice
GC feedback at IFC has nearly zero impact on the design - the team can't redesign at that point without budget impact. GC feedback at 80% CD has medium impact - most decisions are made but adjustments are possible. GC feedback at 50% CD has high impact - major direction is still being set. Helonic supports thorough GC review at earlier milestones than would be possible with staff alone.
GC milestone review
Receive milestone documents
From design team at scheduled milestone.
Run GC-perspective review
Constructibility, cost, schedule, and trade interface focus.
Provide structured feedback
Findings exported in design team's preferred format.
Participate in design discussion
Use findings to anchor substantive milestone meeting discussions.
How Helonic helps
Milestone-appropriate feedback
Comments calibrated to what's reasonable at each LOD.
Constructibility-focused
Issues raised from the constructor's perspective - means, methods, sequencing, trade interfaces.
Cost-impact-aware
Each issue flagged with rough cost implication so the design team prioritizes effectively.
Schedule-impact-aware
Issues affecting construction sequencing flagged for early resolution.
Key features for this workflow
Milestone-appropriate check depth
Constructibility review overlay
Cost-impact estimation per finding
Schedule-impact identification
Trade interface clarification
Owner-decision-required item flagging
Example issues Helonic catches
Real-world issues detected by AI analysis, specific to general contractors running progress set review:
At 30% CD: lateral system change between SD and DD has not been reflected in foundation design
At 50% CD: mechanical room dimensions reduced from SD but equipment selections unchanged - fit conflict likely
At 80% CD: ceiling height reduced to 9'-0" at corridor but mechanical ductwork sized for 9'-6" plenum
At 95% CD: finish schedule introduces tile that wasn't in the early budget - owner decision required
Between 80% and 95% CD: door schedule has 27 more doors than at 80% - verify scope and budget
At IFC: equipment specified for design has 18-week lead time but project schedule shows 12 weeks to need date
What construction professionals told us
“The general contractors we talked with said the milestone reviews where they had the most impact were the ones where they came with specific, document-anchored feedback. Vague 'constructibility concerns' don't move designs; specific findings with citations do.”

FAQs
Does this only work for CMAR/DB?
It works most fully there, but increasingly GCs in design-bid-build also engage at milestones through preferred-bidder relationships. Helonic supports both.
What if the design team doesn't want GC feedback?
Helonic findings can also be used internally by the GC for bid risk assessment and post-award planning. Sharing with the design team is optional.
How often should we run milestone review?
Most GCs run at DD, 50% CD, 80% CD, and 95% CD. Each pass adds incremental value; the earliest passes have the highest impact.
