Excavation project timeline on a Bozeman building site

A Week by Week Look at a Bozeman Excavation Timeline

July 1, 2026

Most people picture excavation as one loud, dusty week of machines tearing up dirt. On a real Gallatin County project it is more like a relay, where each phase hands off to the next on a set schedule. Here is how a typical Bozeman dig moves from a raw parcel to a build-ready pad, and where the delays usually hide.

Week One: Locates, Staking, and the Plan

Nothing gets dug until the 811 Call Before You Dig locate is filed and the utilities mark their lines, which takes about two business days. While those marks go down, we stake the site to the grading plan and confirm elevations. Skipping or rushing this week is how projects hit a buried gas line off Rouse Avenue, so we never start the machines early to save a day.

Week Two: Clearing and Rough Grade

Now the dirt moves. We strip and stockpile topsoil, clear any brush or stumps, and balance cut and fill across the lot to rough grade. This is the loud week neighbors notice. A wet stretch can slow compaction here, which is why we build float into the calendar rather than promising a bone-dry schedule in a Montana spring.

Week Three: Trenching and Utilities

With rough grade set, we open trenches for water, sewer, and electrical. This is the phase where an open cut cannot sit exposed, so we bed, lay, inspect, and backfill inside the same week. If your project needs a full utility run, our trenching and utility excavation work is scheduled tight against the inspection so nothing waits near Baxter Lane.

Week Four: Finish Grade and Handoff

The last phase is finish grading to tolerance and compacting the pad to 95 percent so the foundation crew inherits stable, level ground. Clean site preparation and grading is what lets the concrete pour happen on the date we circled back in week one. Then we pull silt fence, restore the edges, and hand off.

Where Timelines Slip

The two most common delays are a late 811 locate and a surprise in the soil, like rock or a high water table. Both are manageable when they are planned for and expensive when they are not. That is the whole case for a scheduled dig over a book-it-and-hope one.

  • A schedule you can seeYou get a week by week plan from the 811 locate to final grade, not a vague someday promise you have to chase.
  • One crew, one siteEach excavator finishes your milestone before moving on, so a trench near Willson Avenue never sits open for days.
  • Owners vouch for our datesBozeman builders come back because the foundation pour date we set in week one is still standing in week three.
  • OSHA competent person on siteEvery cut 5 feet or deeper is inspected before entry, which keeps your project both safe and on time.

    • Pmcsmith provides land excavation in Bozeman, MT, handling site preparation and grading, land clearing and grubbing, foundation and basement excavation, trenching and utility runs, drainage and erosion control, and driveway and road base prep. We run hydraulic excavators, crawler dozers, and skid steer loaders on projects that move dirt in a planned sequence rather than all at once. Every job follows a calendar you can actually see, starting with the first 811 utility locate and ending at a graded, compacted pad. Builders and homeowners across Gallatin County, from Cooper Park to the University District off Kagy Boulevard, hire us because the schedule we hand over on day one still holds in week three.

    A dig looks like chaos from the curb, but it follows a predictable rhythm. The first week is usually locates and staking. The second is clearing, then mass cut and fill to rough grade. The third moves into trenching, backfill, and finish grade. Weather in the Gallatin Valley can shift that sequence, since a wet spring along Durston Road slows compaction far more than a dry stretch does. We build float into the timeline so a two day rain delay does not cascade into a missed foundation pour. What you get from us is a realistic finish date, not an optimistic one that quietly slips.

    Scheduling is the part most excavation contractors get wrong, and it is the part we obsess over. We do not book three jobs against the same excavator and hope it all works out. Each crew works one site through to its milestone before rolling to the next parcel, which is why a trench that opens on a Monday near Rouse Avenue is inspected, bedded, and backfilled inside that same week. Open trenches invite collapse, citations, and standing water, so we close them fast. Our competent person inspects every cut 5 feet or deeper under OSHA Subpart P before a single boot goes in, and that habit protects both your crew and your calendar.

    We have shaped building pads out in Valley West, cut long utility trenches along Baxter Lane, and prepped gravel driveways toward Four Corners and Belgrade. Every parcel carries its own soil, slope, and drainage story, and reading it correctly is what keeps a dig on time. A lot near Sundance Springs might need a French drain and silt fence to pass its stormwater plan, while a flat pad in the 59718 ZIP just needs clean cut and fill compacted to 95 percent. We study the site before we commit to a date, because a date set on a guess is a date you break. That order, site first then calendar, is the whole difference.

    Scheduling and Duration Questions

    How long does site prep and grading take?
    Most residential pads run one to two weeks from the first locate to final grade, weather permitting. Clearing a wooded lot or moving large volumes of cut and fill adds days on the front end. We hand you a week by week schedule up front so you can line up your foundation crew and concrete pour with confidence.
    Do I need to call 811 before you dig?
    Yes, and we file the 811 Call Before You Dig locate on every job. It takes about two business days for the utilities to mark their lines. We schedule the dig to begin the day those marks are down, so the locate step never becomes the thing that stalls your project near Oak Street or anywhere else.
    How deep can a trench be before OSHA requires protection?
    Any trench 5 feet or deeper needs a protective system, whether sloping, benching, or a trench box, under OSHA Subpart P. Our competent person inspects every cut daily before entry. That discipline is exactly why our trenches open and backfill inside the same week instead of sitting exposed.
    What does 95 percent compaction actually mean?
    It means the fill is packed to 95 percent of its maximum dry density from a standard Proctor test, which is the common spec for a load bearing pad. We place fill in controlled lifts and compact each one, and we can provide density testing so your slab or footing sits on ground that will not settle.
    Do I need a permit or a grading plan to excavate?
    Most projects in Gallatin County that disturb soil need a grading permit, and anything disturbing one acre or more needs a SWPPP for stormwater discharge. We work directly from your engineer's grading plan and keep the silt fence and erosion control in line with the permit through the whole dig.
    How much does it cost to clear an acre near Bozeman?
    Light brush and grass sit at the low end and heavy tree cover with stump grubbing and haul off runs higher, roughly $1,400 to $6,200 per acre. We walk the parcel, whether it is off Baxter Lane or out toward Belgrade, and give you a firm written number before any dozer starts.
    Can you dig a foundation in rocky or wet soil?
    Yes, though rock and a high water table both slow the dig and raise the cost. We plan for dewatering and, where the soil calls for it, import structural fill to build a stable base. A wet spring along Durston Road is exactly the kind of condition we build schedule float around so your pour date holds.

    The Phases Every Excavation Moves Through

    Every project runs through the same core phases, and we treat each one as its own scheduled step on your dig calendar. Here is the work that fills the weeks, from the first dozer pass to the final compaction test.

    Site Preparation and Grading

    Topsoil stripping, cut and fill, and rough to finish grading that shapes a raw parcel to the engineer's plan, setting pad elevations, drainage slopes, and a compacted subgrade ready to build on.

    Land Clearing and Grubbing

    Removing trees, brush, and undergrowth, then grubbing stumps and roots below grade, with haul off or on-site mulching to open a wooded Gallatin Valley lot for construction.

    Foundation and Basement Excavation

    Digging footings, crawl spaces, and full basements to plan depth, with over-dig for forms, spoil management, and a level, compacted bearing surface for concrete footings.

    Trenching and Utility Excavation

    Water, sewer, gas, and electrical trenches with proper bedding and backfill, using a trench box or benching for any cut 5 feet and deeper as OSHA requires.

    Drainage and Erosion Control

    Positive slopes away from structures, swales and French drains, plus silt fence and inlet protection to meet the stormwater SWPPP on any site disturbing one acre or more.

    Driveway and Road Base Prep

    Subgrade compaction, geotextile separation fabric, and placement of crushed aggregate base for a stable, well draining gravel driveway or private road ready to pave.

    Budgeting Each Phase of the Dig

    Excavation cost tracks the phase, the soil, and how much dirt actually moves. Trenching is priced by the linear foot, grading by the square foot, and a bare excavator with an operator by the hour. Rock, a high water table, or poor access all raise the number. The ranges below are typical for the Bozeman area, and we put a firm figure in writing after we walk your site.
