Engineering Cost Guide in St. Louis
Straight answers on what engineering really costs.
MEP engineering
- Four-season MEP systems — St. Louis's continental climate demands heating and cooling systems designed for extreme temperature ranges
- Freeze protection design for piping, HVAC equipment, and domestic water systems in sub-zero winter conditions
- High-efficiency heating plant design with attention to natural gas utility infrastructure and backup heating capacity
- Humidity management for winter-dry conditions — building envelope and mechanical systems must address low RH in heating season
- Snow and ice load coordination between MEP rooftop equipment and structural engineering for heavy snow regions
Structural engineering
- Seismic Design Category B/C — St. Louis area seismicity requires lateral system design and structural detailing above minimum wind-only requirements
- Shear wall and braced frame design for commercial and institutional structures in moderate seismic zones
- Geotechnical coordination to confirm site class and refine seismic design values for site-specific conditions
- Non-structural component anchorage engineering per ASCE 7 for MEP systems and building contents
- Foundation design with attention to site-specific soil amplification in moderate seismic hazard zones
Civil engineering
- Stormwater management design per Missouri NPDES permit requirements and local stormwater authority standards
- Site development and grading plans for St. Louis's active commercial and mixed-use project pipeline
- Land development civil engineering from conceptual site plan through permit-ready construction documents
- Access and utility coordination with local public works, utility providers, and state DOT for site access permits
- Paving, curb, and drainage infrastructure design for commercial, industrial, and institutional site development
