The Short Answer
- Site work schedules range from a few weeks for a small commercial pad to a year or more for large industrial or subdivision projects.
- Earthwork volume, rock, underground utilities, weather and permits are the biggest schedule drivers.
- The fastest jobs have complete plans and permits before mobilization and one contractor self-performing the whole site scope.
How long does site work usually take?
There is no single answer, because site work scales with the project. A small commercial pad with balanced dirt might take a few weeks. A large industrial site or a multi-phase subdivision moving a million cubic yards or more can run many months, often in phases that overlap with vertical construction.
Hillock Farms is one real example: grading started in February 2025 and the job went on to move 1.2 million cubic yards before finishing with topsoil, slope matting and stabilization.
What affects the site work schedule most?
These are the factors that move the timeline more than anything else:
- Earthwork volume and haul distance: more dirt, and dirt that has to leave the site, takes longer
- Rock: ripping, hammering or blasting is slower than moving soil
- Underground utilities: deep sewer and storm runs set the pace on many sites
- Weather and soil moisture: wet clay cannot be placed and compacted until it dries
- Permits and design changes: work cannot start or continue without approvals
- Crew and equipment capacity: how many spreads of equipment the contractor can put on the job
How does weather affect site work in the Southeast?
Rain is the biggest variable in Tennessee and North Georgia. Clay soils hold water, and fill placed too wet will not meet compaction specs. Contractors plan around it by sequencing work so crews can shift to rock, utilities or drier areas, and by keeping erosion controls ready for storms.
How can an owner speed up site work?
Clear the pre-construction checklist before mobilization: approved plans, a geotechnical report, permits and utility locates. Settle the dirt balance in design. And hire a contractor with enough equipment to run multiple crews at once.
Brown Bros. self-performs clearing, excavation, grading, utilities and paving with a 100+ machine fleet, so it can run earthwork and utility crews on the same site at the same time rather than waiting on handoffs between subcontractors.
