New Construction in Tarzana, Sequenced From the Ground Up
New Construction in Tarzana sequenced from clearing and tested fill through pad certification and under-slab inspections, each signed before the next.
Clearing, earthwork and a certified pad come before any concrete on a new Tarzana house. The old structure and its debris leave first. Rough grading then brings the pad to the heights on the civil plan while the soils engineer tests each layer of fill. If the lot slopes and a retaining wall holds the pad, that wall is built and backfilled before footing trenches open, since the pad relies on it.
Fill, density tests and the pad certificate
Fill goes down in thin layers, each moistened and rolled until a technician from the soils engineer's office reads the density it needs. A layer that misses is reworked before the next one starts. At the end of grading, the engineer issues a compaction report and the surveyor checks pad heights against the plan. LADBS asks for that paperwork before it will pass the footing inspection. Erosion control stays in place throughout, with fiber rolls along exposed edges and a gravel pad at the drive so trucks do not carry mud onto the street.
What goes under the slab, and when
Footing trenches are dug and inspected next. The sewer, water, gas and electrical lines that cross beneath the house are then laid in their own trenches and tested, drains with water and supply lines under pressure. Only after the inspector signs for that work do gravel, the vapor retarder and the reinforcing go in. Pouring early would bury untested pipe, and fixing it would mean breaking a new slab. The schedule therefore treats every inspection as a hold point, and the concrete order is placed only when the card is signed.

New Construction in Tarzana: questions
Grading waits on a boundary and topographic survey, a soils report that sets the compaction standard and a civil grading plan that fixes pad heights and drainage. Any structure still standing needs a demolition permit and a hazardous materials survey, covering asbestos and lead, before the first machine arrives.
Earthwork is where it shows most. Importing fill or exporting cut means truck trips, and each truck needs a place to load. When only small loaders fit on the lot, soil moves more slowly and machine hours climb. The trips are counted from the grading quantities, so haul and equipment time appear as lines that can be checked.
Yes, and the price follows the building order, starting with earthwork and ending with finishes. A grading plan with calculated cut and fill lets the site work be priced firmly. If those quantities are not yet available, earthwork is carried as an allowance and replaced once the civil engineer supplies them.
