Engineering Firm Expands its EMI Group in Boston

Waltham, MA – Simpson Gumpertz & Heger’s (SGH) Engineering Mechanics & Infrastructure (EMI) group is making organizational changes to its Boston Division to support continued growth and encourage specialized expertise. SGH’s EMI Boston Division has split into two client-focused, market-facing groups: the Structural Mechanics & Materials (SMM) Division, led by SGH Associate Principal Robert A. MacNeill, P.E., and the Water & Industrial Infrastructure (WII) Division, led by SGH Associate Principal Peter D. Nardini, P.E., P.Eng.

“These changes reflect the incredible growth we have seen from our advanced analytical teams in Boston, and create exciting new leadership opportunities for our team members to deliver key insights for our clients,” said SGH Chief Technical Officer Niklas Vigener. “Rob and Peter are energetic team builders and bold innovators in their fields – I am eager to see where they will lead us.”

The SMM group focuses on four core service areas: nuclear structures, science and defense, materials engineering, and advanced analysis. They specialize in delivering engineering mechanics insights and specialized finite element analysis across a range of structural analysis applications, including composites, seismic assessments, soil-structure interaction, impact, fatigue, contact, and nonlinear response. They also test material properties to identify material defects and anomalies, validate analysis results through physical testing, and push materials to their limits of strength and endurance.

MacNeill has a background in mechanical engineering, with specialized interests and capabilities in the fields of engineering mechanics, nonlinear dynamic finite element analysis, failure investigation, and testing. He is active in the fields of transportation safety, rail infrastructure, and structures vulnerability and protection.

The WII group helps clients manage critical water and industrial infrastructure—including pipes, tanks, culverts, facilities, and offshore structures—for the water, wastewater, transportation, and power generation industries. They have expertise in performing condition assessments, advanced soil-structure interaction and fluid-structure interaction analyses, seismic and blast analyses, failure risk analyses, failure investigations, repairs, laboratory and field testing, and asset management for these complex structures.

Nardini specializes in condition assessment, failure risk analysis, failure investigation, and repair for pipelines. He has particular expertise consulting on concrete, metallic, and HDPE pipelines in the water, wastewater, and power generation industries across the U.S. and abroad.
