Civil Estimating Services

Our civil estimating services address heavy infrastructure and site utility systems including storm drainage pipe networks, sanitary sewer systems, water distribution mains, catch basins, manholes, headwalls, concrete curb and gutter, sidewalks, erosion control measures, and roadway improvements. We quantify pipe by diameter, material type, and linear footage, structures by size and type, and surface improvements by area and linear measurements.

How We Estimate Civil Estimating Projects

Review civil utility plan/profile drawings, storm drainage calculations, and specifications

Quantify pipe by diameter, material, depth, and linear footage per run

Count structures (catch basins, manholes, junction boxes, headwalls) by size and type

Measure curb and gutter, sidewalk, and roadway paving quantities

Deliver comprehensive civil takeoff Excel with marked-up utility plans

Common Civil Estimating Project Types

Typical construction project types that require professional civil estimating services.

Municipal Infrastructure

Public storm sewer systems, water main extensions, and roadway reconstruction for city and county agencies.

Commercial Site Utilities

On-site storm drainage, fire protection water lines, and sanitary sewer connections for commercial developments.

Subdivision Infrastructure

Public street construction, utility installation, detention basin grading, and curb/gutter for residential subdivisions.

DOT & Highway Projects

Highway drainage systems, box culverts, guardrails, signage, pavement markings, and erosion control for transportation projects.

Civil Estimating Challenges We Solve

Pipe Depth Variations

We track pipe invert elevations from plan/profile drawings to calculate excavation depths at each point, which directly impacts trenching costs and potential rock excavation or dewatering requirements.

Structure Complexity

Manholes, catch basins, and junction boxes vary widely in size, depth, frame type, and internal piping connections. We identify each structure individually with all specified components.

Erosion Control Compliance

We quantify all temporary and permanent erosion control measures (silt fence, inlet protection, stabilized construction entrances, riprap) as required by local SWPPP regulations and NPDES permits.

Civil Estimating Takeoff & Estimating FAQ

Do you estimate both storm drainage and sanitary sewer systems?expand_more

Yes. We provide separate takeoffs for storm drainage (catch basins, storm manholes, storm pipe) and sanitary sewer (sewer manholes, sewer main, laterals). Each system is independently quantified with its own pipe materials, structure types, and connection details.

Are roadway and pavement quantities included in civil estimates?expand_more

Yes. We measure roadway paving areas by surface type (asphalt, concrete), calculate sub-base thicknesses and aggregate tonnage, and quantify curb and gutter, sidewalks, ADA ramps, and pavement markings.

How do you handle dewatering and rock excavation allowances?expand_more

When geotechnical reports indicate shallow groundwater or rock encountered at trench depth, we identify affected pipe runs and flag them separately in the estimate so contractors can apply appropriate unit rate premiums for dewatering or rock removal.
