What Happens Between Site Work and Final Occupancy

Your project starts with site preparation, which includes clearing, grading, and installing temporary utilities in Spring Valley. Once the site is ready, the foundation is poured and allowed to cure before framing begins. Structural work progresses floor by floor or section by section, with rough-ins for plumbing, electrical, and HVAC completed before walls are closed up.

When construction is finished, you walk into a building that is ready for furniture, equipment, and staff. The HVAC system heats and cools as specified, electrical panels are labeled and functional, and doors and windows seal properly against weather.

Material selection is locked in early based on your budget and the building's intended use. Steel framing may be used for larger spans, while wood framing works for smaller structures. Roofing, siding, and interior finishes are chosen for durability and code compliance, not just appearance. Weather delays are managed by adjusting the schedule for trades that can work indoors while exterior work waits for dry conditions.

We know building from scratch brings up a lot of questions

Owners planning new construction usually want to understand the timeline, how site conditions affect the project, and what decisions need to be made before breaking ground.

How long does it take to complete a commercial building from start to finish?
A typical commercial building in Spring Valley takes six to twelve months depending on size, complexity, and weather. Smaller retail or office buildings finish faster, while larger structures with custom systems take longer due to permitting, inspections, and material lead times.
What site conditions can delay construction or increase costs?
Poor soil that requires additional compaction, high water tables that need drainage systems, or buried debris from previous structures can all add time and cost. A geotechnical survey identifies these issues before construction begins so they can be planned for in the budget.
When do I need to finalize interior layouts and finishes?
Interior layouts should be finalized before framing starts, and finishes like flooring, paint, and fixtures need to be selected before rough-ins are complete. Late changes can delay the schedule and increase costs if materials need to be reordered or work needs to be redone.
What inspections are required during construction?
You will have inspections for the foundation, framing, electrical rough-in, plumbing rough-in, HVAC installation, fire safety systems, and final occupancy. Each must pass before the next phase of work can begin, so scheduling is built around inspection availability.
How do you handle material price increases during a long project?
Contracts include terms that address material cost changes, either by locking in prices at the start or allowing adjustments if market conditions shift significantly. You are informed of any changes before they are applied to the project budget.
