H.B. Fleming was founded in 1955 by Howard B. Fleming and Ray Erickson with a focus on pile driving and marine work. In 1993, Dean Sciaraffa and John Linscott III purchased the company, expanding the scope of services to include design-build solutions for excavation support systems, cofferdams, ground improvement, subaqueous pipelines, retaining walls, and drilled shafts. In 2015, Dean and John sold the business to John “Scotty” Linscott IV and David Gifford who have continued expanding in size and scope. Dean Sciaraffa continues to serve as corporate director and maintains an active role in the company’s daily activities.

H.B. Fleming has earned a reputation for quality, cost-effective geotechnical design-build solutions. Our ability to rapidly mobilize equipment and problem-solve has led to many long-term client and partner relationships. 

We would be nowhere without our skilled workforce, which has grown to approximately 50 AWS-certified welders, NCCCO-licensed crane operators, and experienced pile driving foremen. Most of our field leadership began their careers here as welders or laborers. That kind of longevity is like gold.

The majority of our work involves cranes. We currently have nine crawler cranes with capacities ranging from 30 to 110 tons, and a wide range of support equipment, including:

  • Nine diesel impact hammers, with rated energies ranging from 30,000 ft-lb to 90,000 ft-lb
  • Drop-hammer and air-operated impact hammers
  • Seven vibratory drivers/extractors with driving forces ranging from 50 to 100 tons
  • Numerous sets of fixed and swinging box-style hammer leads

We have three excavators than can be fitted with high-torque drive motors for installing helical piles and soil anchors.

We own eight hydraulic drive motors with varying torque ratings to accommodate a broad range of pile/anchor sizes and configurations.

Our drilling equipment currently consists of a Soilmec SR-30 and a REVDrill 34HD. We have several pieces of drill tooling and casing, along with an array of drilling support equipment.

Our ground improvement work is centered around our Bauer/RTG RG 19T pile driver with telescopic leader. The RG 19T is outfitted with a powerful, high-frequency variable moment vibratory hammer and a patented, VIPAC mandrel system that can be configured for use with stone columns or rigid inclusions. This machine can also be used to install sheet piles or H-piles in an extremely productive manner.

We keep our people and our equipment moving with a small army of trucks and trailers. We own two heavy truck/tractors, two lowbed trailers, several flat deck trailers, and numerous service trucks, rack trucks, and pickup trucks. We also maintain a large inventory of sheet piles, casing, H-pile, and pipe pile.

Safety First

We work hard to maintain a workplace environment that fosters the health and well-being of our employees. And we trust our employees to make good decisions on the job to keep themselves and their coworkers safe.

Our field crews have weekly toolbox talks to discuss potential jobsite hazards and how to prevent them. We rely heavily on the technical experience and expertise of our field leadership. Many of our supervisors began their careers as welders or operators at H.B. Fleming and carry the lessons learned into their current roles. This level of seniority and preceptorship translates to a safer jobsite and more safety-conscious employees.

All of our employees have completed OSHA 10 training as well as certified rigger/signalperson training, and many have completed 40-hour HAZWOPER training. Our crane operators are NCCCO-certified, and most have Massachusetts hoisting engineer licenses.
