**Rating: 2.6/5** (low confidence) — from 2 reviews across 6 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.

## The honest read

Delphi Construction is a commercial construction manager and general contractor working from two Massachusetts offices — one in Waltham and one at 17 Cape Drive in Mashpee. The company traces itself to 1992, when a healthcare client it had served as owner's representative asked it to take on construction management for a hospital project, and it names Jake Simmons as owner and executive chairman with Keith Shaw as president.

The work is institutional rather than residential. Its stated markets are healthcare, assisted living, affordable housing, multi-family residential, banking, religious, corporate, education and modular construction, and the projects that show up publicly match: it was the general contractor on the Brewster Fire Headquarters, whose January 2017 groundbreaking brought out town officials, the fire station building committee and residents, and it has built Harborwalk at Plymouth Station. A homeowner looking for a kitchen or an addition is not this firm's customer.

The customer-review trail is short and dated. Google shows 2.5 stars from 2 ratings, and both written accounts are old: a 2017 reviewer wrote "Great builders. Beautiful homes, great work.", while a 2021 reviewer left a flat "dishonest and inferior." with nothing about what happened. Two opposed one-liners, five and nine years back, is a thin basis either way — the specific, checkable record here is in the buildings, not the reviews.

On safety the picture is mixed and worth raising directly. The company advertises ABC STEP safety awards at Gold, Platinum and Diamond levels, and a federal safety record lists three OSHA citations across three standards carrying $2,900 in proposed penalties, from an inspection opened in 2017. Those are small penalties by construction standards, but they sit against a strongly safety-forward self-presentation, so ask how the citations were resolved.

A couple of the numbers also disagree. The company dates itself to 1992 and claims 34 years in business; its Better Business Bureau profile records a 2001 incorporation and 24 years, with 81 employees, an A+ grade, no accreditation and nothing filed against it. A Procore listing tags its only trade as "Earthwork", which matches nothing else on file.

For a town, school, healthcare operator or housing developer on the Cape or in Greater Boston, this is an established construction manager with municipal and institutional work you can go look at, including a fire station in Brewster. Before signing, ask which office would run your job, ask for references on a project of your type and size, and ask about the 2017 OSHA citations.

**Strengths:**
- Municipal buildings — general contractor on Brewster's fire headquarters
- Institutional construction — schools, healthcare and assisted-living work across Massachusetts
- Passive-house capability — states PHIUS, LEED and Net-Zero certified construction
- Clean BBB file — A+ grade with nothing filed against it

**Concerns:**
- OSHA citations — three citations, $2,900 proposed penalties, 2017 inspection
- Harsh 2021 review — called them dishonest and inferior, no detail given
- Commercial focus — stated markets are institutional, not home improvement
- Dated feedback — the two written reviews date from 2017 and 2021

**Where sources disagree:**
- The company advertises ABC STEP safety awards at Gold, Platinum and Diamond levels, while a federal safety record lists three OSHA citations and $2,900 in proposed penalties from an inspection opened in 2017.
- The company dates its founding to 1992 and states 34 years in business, while its Better Business Bureau profile records a 2001 incorporation and 24 years in business.
- A Procore Network listing tags the firm's only trade as "Earthwork", which conflicts with the commercial construction-management and general-contracting work described on its own site and by the Better Business Bureau.
