Standby Generator Pads & Conduit
Standby Generator Pads & Conduit in Southern Oregon
Level concrete and composite generator pads, electrical and gas conduit trenching, and full site prep across the Rogue Valley, ready for your electrician and plumber to make final connections.
Overview
The excavation and pad partner that gets your generator ready to connect
Installing a standby generator involves more trades than most people expect. Before your electrician and plumber can make the final connections, the site has to be ready: a level, properly sized pad, conduit runs in the ground, drainage around the unit, and the area restored. That groundwork is where Pacific Earthworks comes in.
We handle pad excavation and base prep, pour or set the concrete or composite generator pad, trench for electrical conduit from the generator location to your transfer switch or panel, and trench for gas line conduit. We coordinate with your licensed electrician and plumber so the conduit runs terminate in the right location and the site is clean and ready when they arrive to make final connections.
For rural Rogue Valley properties where power outages are a real consideration, getting the site work done right the first time means your generator install goes smoothly from pad to power.

Generator Site Prep FAQs
What does generator site prep include?
Pacific Earthworks handles pad excavation and base prep, the concrete or composite generator pad, electrical conduit trenching from the generator to your transfer switch or panel, gas line conduit trenching, drainage around the pad, backfill, compaction, and site restoration. Final electrical and gas hookups are completed by your licensed electrician and plumber. We coordinate with them so the site is ready for those connections.
How much does a generator pad cost?
Generator pad cost depends on the pad size, the material (concrete versus composite), the amount of excavation and base prep required, and how much conduit trenching is needed. Properties with longer runs or difficult ground conditions cost more than straightforward installs. The best way to get an accurate number is a free on-site quote, call (541) 512-5280.
Do you do the electrical and gas hookup?
No, and we are upfront about that. Pacific Earthworks handles the pad, excavation and base prep, electrical conduit trenching, gas line conduit trenching, and all site prep work. Final electrical connections and gas connections are completed by your licensed electrician and licensed plumber. We coordinate with those trades so the conduit runs are in place and ready when they arrive.
What size pad does a standby generator need?
Pad size depends on the generator unit. Most residential standby generators are placed on pads ranging from roughly 3 by 5 feet to 4 by 7 feet or larger for higher-output units. We size the pad to your specific generator model and manufacturer requirements, with adequate margin around the unit for service access.
How far can the generator be from the house?
Placement is influenced by manufacturer clearance requirements, local code, fuel source proximity, and noise considerations. Generators typically need to be several feet from the structure and away from windows and doors. The conduit runs for electrical and gas can accommodate a range of placement distances. We help you think through placement before any digging starts.
Do you serve rural properties around the Rogue Valley?
Yes. Pacific Earthworks is based in Williams and regularly works on rural properties throughout the Rogue Valley and Southern Oregon. Rural properties with long conduit runs or challenging site access are well within our scope, and a reliable backup generator is a practical necessity for many properties in this region.
