From our president
“I started out drilling mines around the world where the ground doesn't forgive shortcuts. Since then I've drilled across Greater Boston and become a specialist in its bedrock. That discipline is why Boston brings us its hardest jobs — airport work, one of the largest excavation-and-drilling jobs the city has run, the transit-line extension. We do the buried work right, keep the GC on schedule, and stand behind every foot of it.”

How we work
Inspection to start, without the guesswork.
01
Inspection
We visit the site, review the geotech and the constraints, and scope the support-of-excavation or foundation work with you.
02
Quote within 3 days
You get a detailed, line-item quote — technique, sequence, and assumptions spelled out — within 3 days of the inspection.
03
Start
On award, we mobilize to the agreed window and drive, drill, or shore — sequenced to keep your dig on the critical path.

How we’d build it.
Composite sites, worked through the way we would work through yours. Illustrative examples — not completed ESC projects.
Soldier pile & lagging · Cantilever wall · Slope where there's room
Shoring an infill basement with the neighbor four feet away
A new four-storey building with a full basement on a double-width lot, an old masonry neighbor four feet past the line and open ground elsewhere. How we'd put a wall only where one is needed — drilled, cantilevered, nothing under the neighbor — and lay the rest of the cut back.
How we’d approach itUnderpinning · Groundwater overlay · Party walls
Lowering a rowhouse cellar over timber piles, inside the groundwater overlay
A mid-row brick rowhouse on filled land, its walls on granite over timber piles, with the groundwater about a foot above the pile tops. How we'd take the cellar floor down about two feet without moving the water, or the piles.
How we’d approach itSoldier pile & lagging · Tiebacks · Street permissions
Holding a garage excavation along a city street, with tiebacks under the public way
A mid-rise building over a one-level garage that runs to the sidewalk. How we'd hold the street side with soldier piles and one row of tiebacks, once the City agrees they can go under the street, and brace the neighbor's side from inside the hole.
How we’d approach it
Engineering & construction data services
We build the data we estimate from — and we build it for clients.
Every price we quote, every ground assumption we make, comes out of datasets we assembled ourselves from public records, because the ones we could buy were not good enough. Those datasets are now a service in their own right. Each one is observed record only — nothing modelled, nothing estimated, blank where the record is blank, and every row traceable to the document it came from.
Insurance
Contractor renewal intelligence
1,082 New England contractors with a general-liability policy in force — carrier, renewal date, incumbent agency and a way to reach the business. Built from certificates filed on public permits.

From the field
Where we work
Greater Boston ground, neighborhood by neighborhood.
We engineer to the Boston Basin: urban fill, Boston Blue Clay, glacial till, and argillite. Each area has its own subsurface story.
See projects near youOutside Boston? Look up any New England town in Ground Truth — depth to bedrock, bridges and dams.
Back Bay & South End
Nineteenth-century fill over tidal mud and thick marine clay, with rock at a median depth of 123 ft in public logs. Buildings stand on wood piles, and nearly all of the land is inside the GCOD.
Beacon Hill
Dense glacial till under the hill and nineteenth-century fill over the river flats below it; rock is deep under both, and the flat is inside the GCOD.
South Boston & Seaport
Glacial drumlins and shoreline fill inland; the Seaport is made land on the harbor flats over soft clay, with rock at a median depth of 82 ft in public logs.
Cambridge & Somerville
Filled river flats, marine clay and glacial sand in Cambridge; thin till over shallow argillite across much of Somerville. Median depth to rock in public logs: 57 ft in Cambridge, 27 ft in Somerville.
Jamaica Plain & Roslindale
Thin till over Roxbury Conglomerate (puddingstone) on the hills and glacial sand and gravel in the valleys; the middle half of public logs found rock between 15 ft and 101 ft.
Allston-Brighton
Filled river flats over clay and sand in Allston; thin glacial till over Roxbury Conglomerate on Brighton's hills, with outcrops in places.
