What we do

Six core scopes. One accountable contractor.

We self-perform the technical scopes that drive a public-works schedule — and carry in-house survey, SWPPP/QSD and backflow certification — so agencies deal with one contractor and one set of answers.

Full project list
Self-performed · in-house

Our own survey crew. Our own drill rigs.

Most contractors our size rent this capability or sub it out. Zeco owns it — which means layout happens the day we mobilize and utilities go in without waiting on anyone.

Survey & layout

In-house survey & layout

Our own crew performs construction layout and as-built survey with Trimble robotic survey equipment — staking fields, courts, curbs and utilities straight from the CAD model. No waiting on a survey sub, no layout change orders.

  • Sports-field & court layout to the hundredth
  • Curb, walk & ADA grade staking
  • As-built topo for closeout
Trenchless

Directional boring

Our own Ditch Witch directional-boring equipment lets us install irrigation mainlines, electrical conduit, water and sewer laterals under existing turf, trees, walks and streets — without open trenching. Parks stay open and mature trees stay standing.

  • HDD bores for conduit, PVC & HDPE
  • Air / vacuum excavation for utility potholing
  • Crossings under walks, roads & root zones
Underground & earthwork

Wet utilities, storm drain & grading

Storm drain, water lines, sewer, irrigation mainlines and site electrical, plus the mass grading and fine grading that sports fields demand — performed by our own union operators and pipe crews.

  • Storm drain, catch basins & area drains
  • Water & sewer laterals, backflows, POCs
  • Laser / GPS-guided grading & import-export
