New Construction in San Fernando, Starting With the Service Design
New houses in San Fernando sequenced from the utility service design: temporary power, the trench and conduit, sleeves under the slab, then the pour.
Before a footing is dug on a new San Fernando house, the electric utility has to design the service, because that design fixes where the meter sits and how the line reaches it, overhead or in conduit under the yard. An application with the load calculation, including solar and any vehicle charging, starts it. While the utility works, a temporary power pole is set for the build, and the trench and conduit are planned to go in before the slab is formed.
Temporary power and the route to the meter
The temporary pole carries a meter and outlets for the trades, and it has to stand where the utility's crew can connect it and where it will not block the pad or the trench. The final service route runs from the utility's pole or vault to the meter location the utility approves, usually on the side of the house facing its equipment. Any transformer upgrade the load calls for is the utility's decision, and a pad for one may land on the lot. Gas, if the house has any, and water follow the same order: meter location first, then the trench.
Sleeves and stub-ups before the pour
Under-slab work comes next, and all of it goes in before concrete: electrical conduit from the meter to the panel, sleeves for future circuits, the sewer and water lines with their cleanouts, and the stub-ups for each fixture, held at the heights the plumbing plan sets. Drain lines under the slab are filled and held under test while the inspector looks. Underground work is signed off by the city inspector first, then the forms and steel, and after that the pour can be scheduled. A conduit forgotten now means cutting the slab later.

New Construction in San Fernando: questions
A service request to the electric utility, with the new house's load calculation, is filed at the start, since the utility's review sets the meter spot and any transformer work. Surveys, a soils report and a locate of existing lines on the lot are ordered alongside it, so old gas, water and sewer runs are capped where they actually lie.
Distance from the utility's pole or vault to the meter sets the trench, which is priced by its length and depth. A frontage with room to set the temporary pole and a bin keeps the early work simple. Where the service must pass under a driveway or patio that is staying, it is bored under, which costs more per foot than an open trench.
The architect's set rarely shows the utility's part of the work, because the utility draws it after the permit drawings are under way. So the service trench, conduit and any transformer pad are priced once the utility's layout arrives, as an allowance until then. The house itself is priced from the drawings, and demolition, if there is an old house, is scoped on a site visit.
