Basalt Excavation & Concrete

For builders, GCs & developers

The iron, the tonnage, and the bid.

Everything an estimator normally has to phone in and ask for: what we run, what scale we handle, how a bid gets built, and the standards we hold ourselves to.

No rental calendar, no waiting on a dealer to free up a dozer. If a machine goes down mid-job we swap it out of our own yard the same day.

02 Project types & scale

What a job this size actually looks like.

Real ranges from our last three years of work — so you can sanity-check a budget before you ever pick up the phone.

  • Single-family lot

    01

    600 – 2,400

    yd³ moved

    Strip, cut the pad, dig footings, set the lateral, backfill and finish grade. Usually one crew and two machines start to finish.

    3 – 8 working days
    • Pad to ±0.10 ft
    • Lateral + storm
    • Driveway subgrade

  • Multi-lot subdivision

    02

    8,000 – 30,000

    yd³ moved

    Mass balance across the plat, road prism and rock, joint utility trench, and pads released to the builder in phases so framing never waits.

    6 – 16 weeks
    • GPS machine control
    • Phased release
    • Third-party density

  • Commercial pad & parking

    03

    4,000 – 18,000

    yd³ moved

    • Fiber or #4 mesh
    • Cure & seal

  • Driveway replacement

    05

    600 – 2,000

    3 – 6 working days
    • Old slab recycled
    • 5" pour
    • 10–12 ft joints

  • Demolition & clearing

    06

    1 – 12

    structures / acres

    Disconnects, permits, structure down, foundations out, loads sorted for recycling, lot left rough-graded and seeded if you want it.

    2 days – 3 weeks
    • Permit pulled
    • Loads sorted
    • Rough-grade out
03 How we bid

Five days, five steps, one number.

Written the way we run it, not the way it sounds good in a brochure. If any step is going to slip, you hear about it before the deadline, not after.

  1. 01 You

    Send documents

    Civil sheets, geotech, plat or plot plan, and any schedule constraints. PDFs are fine. If it's a residential job, three photos and a tape measurement will do.

    Turnaround

    Acknowledged same day

  2. 02 Basalt

    Site walk & takeoff

    An estimator walks it — grades shot, soil checked, access measured, spoil and import assumptions written down instead of guessed at.

    Turnaround

    Within 2 business days

  3. 03 Basalt

    Line-item proposal

    Yardage, truckloads, rock tonnage, concrete yards, permits, testing and mobilizations — priced separately so you can see what moves when scope moves.

    Turnaround

    Day 5, in writing

  4. 04 Together

    Scope review call

    Twenty minutes to walk the exclusions and the assumptions. This is where the change orders get killed before they exist.

    Turnaround

    Before award

  5. 05 Basalt

    Schedule & mobilize

    Signed dates on your calendar, submittals and certs to your PM, machines on a lowboy. Daily photo log for the whole duration.

    Turnaround

    Dates held in writing

Prequal packet

Everything a GC's compliance desk asks for, already assembled. Ask and it's in your inbox the same day.

  • Certificate of insurance, additional-insured endorsement
  • Payment & performance bond capacity to $3M
  • EMR letter and OSHA 300 logs, three years
  • Written safety program & competent-person roster

Ground conditions

Willamette clay, river rock,
and the basalt shelf.

Seventeen years in this valley means we've already hit whatever is under your lot. Wet winter clay, cobble at four feet, a basalt shelf that eats a bid — we price for it up front, and the breaker is already on the trailer.
