MEP Subcontractor — Healthcare Facility
Representative scenario based on typical Helonic usage patterns
412 MEP coordination issues
$180K avoided field conflicts
Above-ceiling & medical gas
The Challenge
An MEP subcontractor was awarded the mechanical and plumbing scope on a 180,000 SF hospital expansion. Healthcare construction demands extreme coordination precision — above-ceiling spaces are packed with ductwork, piping, cable trays, medical gas lines, and pneumatic tube systems, all competing for the same 18-inch plenum space.
The design team's drawings showed medical gas routing that crossed through the planned HVAC trunk duct paths in multiple patient room corridors. The plumbing riser diagram didn't account for the structural transfer beams added in the latest revision. And several isolation room exhaust systems referenced a duct size on the mechanical plans that conflicted with the infection control narrative in the specifications.
The subcontractor's estimating team flagged these as risks during bid review, but needed a systematic way to quantify the full scope of coordination issues before locking their price.
How They Used Helonic
The team uploaded the full MEP drawing set along with the architectural reflected ceiling plans and structural framing plans to Helonic. The analysis focused on above-ceiling coordination, medical gas routing, and infection control compliance — the three areas that drive the majority of healthcare MEP change orders.
Helonic's analysis identified 412 coordination issues, with the highest-severity findings concentrated in three areas: 87 above-ceiling conflicts where ductwork, piping, and cable trays occupied the same physical space; 43 medical gas routing conflicts where lines crossed through structural members or ductwork; and 29 infection control compliance gaps where exhaust systems didn't match the pressure relationship requirements.
The remaining issues included plumbing stack conflicts, electrical panel clearance violations, and fire damper locations that were inaccessible for required maintenance access.
Results
The subcontractor used Helonic's issue report to build a detailed coordination log that was presented to the general contractor and design team at the next OAC meeting. Rather than raising issues one at a time during construction, they delivered a comprehensive report that forced resolution during design — when changes cost 10x less.
The team estimated $180,000 in avoided field conflicts, primarily from medical gas rerouting that would have required structural core drilling and above-ceiling rework that would have triggered re-inspection of completed infection control barriers.
The coordination report also strengthened the subcontractor's position during contract negotiations. By demonstrating a thorough understanding of the drawing conflicts, they were able to negotiate appropriate contingency and ensure that resolution of design coordination issues was clearly the responsibility of the design team — not a field-fix burden on the subcontractor.
“Healthcare MEP coordination is where careers go to die. Helonic caught 87 above-ceiling conflicts and 43 medical gas routing issues that would have been nightmare change orders. We presented them all before breaking ground.”
Frequently Asked Questions
Does Helonic understand healthcare-specific requirements like infection control?
Helonic's analysis includes checks for pressure relationships in isolation rooms, medical gas routing clearances, and other healthcare-specific coordination requirements. It cross-references mechanical system layouts against infection control narratives to flag discrepancies.
Can MEP subcontractors use Helonic during the bidding phase?
Yes. Many subcontractors use Helonic during preconstruction to quantify coordination risk before locking their price. The analysis provides a defensible basis for contingency and clarifies which coordination issues should be resolved by the design team.
How does Helonic handle above-ceiling coordination specifically?
Helonic cross-references reflected ceiling plans, structural framing plans, and MEP layouts to identify spatial conflicts in above-ceiling zones. It flags ductwork that intersects structural members, piping that conflicts with cable trays, and equipment that violates required maintenance clearances.
What happens when issues are found across multiple MEP disciplines?
Issues are categorized by type and discipline, so you can sort by mechanical-plumbing conflicts, electrical-structural conflicts, or any other cross-discipline combination. Each issue includes the specific sheet references for both sides of the conflict.
