Installing Storm Drain Pipe

A field guide to storm drain pipe installation: trench width and bedding classes, invert grade and minimum slope, jointing, haunch compaction, backfill, and deflection testing.

Removing an Underground Storage Tank

A step-by-step guide to underground storage tank removal: closure rules, notification, emptying and purging, excavation and lifting, soil sampling, and the closure file that protects the property.

Excavation Takeoff Methods

A practical guide to excavation takeoffs: grid, average end area, prismoidal, and surface-to-surface volume methods, plus the swell, strip, and compaction adjustments that keep a bid honest.

Trench Collapse Rescue

A trench collapse rewards planning and punishes instinct: the first-minutes response, why would-be rescuers die, and the plan OSHA expects before the dig.

Concrete Washout on a Construction Site

Concrete washout is a regulated discharge, not housekeeping: how to size, site, line and maintain a washout that holds up through a pour day.

Traffic Control for Excavation Work

Roadway excavation needs a work zone built from the MUTCD: advance warning, calculated tapers, buffer space, flaggers, plates, and a documented closeout.
