Engineering in Lewiston

Services in Lewiston

MEP engineering

• Four-season MEP systems — Lewiston'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

• Wind-governed lateral design — Lewiston's low seismicity means wind loads control lateral structural system design
• Steel moment frames, wood shear walls, and masonry structural systems designed to the IBC and ASCE 7 for the local wind exposure category
• Foundation design for local soil conditions — expansive clays, sandy soils, and clay shrink-swell issues vary across the region
• Roof structural design with attention to local wind uplift and, where applicable, snow accumulation requirements
• Load path continuity engineering for commercial and institutional structures under governing gravity and wind demands

Civil engineering

• Stormwater management design per Maine NPDES permit requirements and local stormwater authority standards
• Site development and grading plans for Lewiston'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
