Professional Storm Drainage Estimating

Professional Storm Drainage Estimating for Contractors, Municipalities & Infrastructure Developers

Storm drainage systems are among the most critical infrastructure components on any commercial, municipal, or residential development project. Every pipe run, manhole, catch basin, culvert, and inlet carries material cost, excavation depth, and installation complexity that directly impact your bid accuracy. An incomplete drainage takeoff or missed manhole structure can expose a contractor to significant change orders and project delays before the first pipe is laid.

The Virtual Estimation provides professional storm drainage estimating services for general contractors, civil contractors, utility contractors, municipalities, site work contractors, and infrastructure developers across all 50 US states. Our estimators measure every pipe run, count every manhole, catch basin, inlet, and structure from the civil drawings and deliver a complete bid-ready estimate within 24 to 48 hours.

We use PlanSwift and Bluebeam Revu for digital takeoffs, RSMeans for regional pricing by zip code, and civil engineering specifications for pipe sizing, material selection, and structure details specific to your project drainage requirements. All estimates are delivered in Excel organized by specification section ready for bid submission.

Who We Serve

  • General Contractors: GCs use our storm drainage estimates to evaluate subcontractor bids and carry accurate allowances for storm sewer, culvert, and drainage installation scopes on commercial and residential projects.
  • Civil Contractors: Civil contractors use our takeoffs to price storm sewer systems, detention facilities, and drainage improvements for site development and infrastructure projects.
  • Utility Contractors: Utility contractors use our estimates to price storm sewer installation, manhole and catch basin structures, and drainage pipe networks for municipal and private development work.
  • Municipalities: Municipal project managers use our storm drainage takeoffs to budget for street storm sewers, subdivision drainage systems, regional detention facilities, and public infrastructure improvements.
  • Site Work Contractors: Site work contractors use our drainage estimates to price grading, storm sewer, retention and detention, and erosion control packages for land development projects.
  • Infrastructure Developers: Infrastructure developers use our storm drainage takeoffs to price large-scale drainage networks, regional stormwater management systems, and public utility extensions for master-planned communities and commercial developments.

What Our Storm Drainage Takeoff Covers

A complete storm drainage takeoff measures every pipe run, counts every manhole, catch basin, inlet, and structure shown on the drainage plans and utility profiles. Estimators who count only the mainline pipes and omit structures, bedding, excavation, backfill, and compaction consistently underbid storm drainage scopes by 15 to 25 percent. Our takeoffs are complete by design.
