Sitework Estimating Services

Earthwork, Grading & Site Utility Takeoffs

Plane Estimates delivers thorough sitework estimating services covering the full scope of civil and site construction — from initial earthwork and cut/fill calculations through underground utilities, stormwater management, paving, curb and gutter, landscaping, and erosion control. Site costs are often underestimated because the work spans many disciplines and the quantities are driven by terrain, soil conditions, and civil engineering details that require careful reading of grading and utility plans.

Our earthwork estimates are based on careful analysis of existing and proposed grade contours, cross-sections, and grading plans. We calculate cut and fill volumes in cubic yards, identify mass haul requirements, and note where import or export material is indicated. Shrink and swell factors are applied based on soil classification references in the geotechnical report when it is provided, giving you a more reliable net earthwork quantity.

Underground utility scopes — sanitary sewer, storm drainage, water main, dry utilities, and site electrical — are estimated by pipe size, material, and depth of cover. We include trench quantities, bedding material, and backfill alongside the pipe and structure counts so your utility subcontractor has a complete quantity set. Stormwater management features including detention ponds, bioretention cells, and underground systems are quantified from the civil grading and drainage plans.

Sitework estimating is a paid professional service at Plane Estimates. You receive an organized Excel estimate covering earthwork volumes, utility pipe and structure quantities, paving areas by type, and landscaping quantities — everything your site contractor needs to build a competitive bid from a solid quantitative foundation.
