New Construction on Your Culver City Lot
New house construction in Culver City that digs for old footings, buried slab and loose fill before the foundation is designed and the build is priced.
A lot that once held another house can hide pieces of it underground. On a Culver City parcel we look for old footings, a buried slab, abandoned pipes and pockets of loose fill before the new foundation is designed. Test pits at the old house lines and a soils engineer's borings show what is down there. If remnants turn up, the footing plan changes, and so does the price, so we find them before the plans are final.
What the test pits turn up
We dig where the old walls, porch and garage stood, using an earlier survey or aerial photos as a guide. Old concrete footings can sit right where a new one needs to go, and broken slab buried as fill leaves voids the soil cannot close. Abandoned sewer and water lines are traced and capped so they cannot leak into the new trench. Clay pipe, rusted steel and debris are logged with photos. The soils engineer then decides whether the loose material must be dug out and replaced with compacted soil.
How a finding changes the foundation
Remnants that sit clear of the new footprint can often stay where they are. Those under a new footing are broken out and hauled away, and the hole is backfilled in tested lifts. Where fill runs deep, the engineer may call for over-excavation across the whole pad or deeper footings at one corner. Each choice moves the concrete and labor in the estimate, which is why the test pits happen first. Culver City's building safety staff review the soils report with the plans, and the inspector checks the cleaned-out trenches before steel goes in.

New Construction in Culver City: questions
Anything about what was there before helps. Old permits, a prior survey or photos of the earlier house show where to dig test pits. Beyond that we need a current boundary survey, a soils report, the zoning limits and the utility connection points. Together they tell the designer what the lot can carry.
Plans and permits come first, under a price of their own. Once Culver City approves them, the build is quoted in the order it is built: demolition and site work, the foundation, framing, the roof, the trades inside the walls, then finishes. Removing any buried remnants is a separate line tied to what the test pits found.
We coordinate them. The surveyor maps the lot and the old house lines, the soils engineer uses that map to place borings and test pits, and the structural engineer designs from the soils report. We keep their documents consistent, hand them to your designer, and answer the city's comments through whichever consultant owns each one.
