Nationwide Civil Engineering Services
Plump Engineering, Inc provides comprehensive civil engineering services tailored to the needs of each project, designed to earn approvals and hold up in the field.
Our Integrated Civil Engineering Services
Civil engineering carries a project through some of its most scrutinized reviews: city plan checks, water quality requirements, utility agencies, and public works standards. Our team designs with those hurdles in mind from the start, producing grading, drainage, and utility plans that agencies can approve and contractors can build without a stack of clarifications.
Through continuous coordination across all site and building disciplines, our team aligns civil design directly with architectural and structural parameters. From grading and earthwork to utility infrastructure, we deliver well-integrated site plans that move projects steadily from permitting to construction.
Construction and Grading Plans
Precise grading and construction documents that balance earthwork, manage slopes, and set the pads, drives, and drainage patterns your project is built on.
Hydrology and Hydraulic Analysis
Runoff modeling and hydraulic calculations that quantify how water moves through your site, forming the engineering basis for drainage design and agency approval.
Detention and Retention Basins Design
Basin design that manages peak flows and water quality requirements, sized to protect downstream properties and satisfy the reviewing agency.
Stormwater Pollution Prevention Plans
SWPPP preparation that keeps your project compliant with construction stormwater permits, protecting water quality and keeping inspections uneventful.
Domestic Water and Sewer Plans
Water and sanitary sewer design from point of connection through the site, coordinated with serving agencies and engineered for reliable long-term service.
Dry Utility Coordination
Coordination of power, gas, and communications providers, aligning trenches, easements, and schedules so dry utilities arrive when the project needs them.
Street, Traffic Control, and Lighting Plans
Street improvement, traffic control, and lighting design to public works standards, covering the frontage and offsite work your conditions of approval require.
Permit Processing
We shepherd plans through the agencies ourselves, responding to plan check comments and tracking approvals so permits arrive on schedule instead of on the critical path.
Site & Structure, Aligned from Day One
Successful development relies on seamless interaction between the site and the building. At PEI, civil engineers collaborate directly with our structural and architectural teams throughout the design process.
From grading and earthwork that match foundation requirements to precisely routed utilities, early cross-discipline coordination helps prevent field adjustments and delivers unified drawings ready for agency approval.
