Construction Engineering

GZA’s construction engineers design the temporary works, demolition procedures, erection plans, and lift plans that contractors use to build, rehabilitate, and remove bridges, buildings, and other complex structures. With Siefert Associates now part of GZA, our team brings decades of contractor-focused construction engineering to projects across the Northeast and beyond.

GZA’s construction engineers know how structures go together, how to support them temporarily, how to put them up, and how to take them down in a practical, economical way. We work on heavy civil, transportation, industrial, commercial, waterfront, and building projects, on new construction and on structures that have been in service for decades.

Many of our engineers came from the contractor side, and our work reflects it. We prepare demolition and erection procedures, staged construction analyses, temporary supports and bracing, engineered lift plans, and rigging designs based on the equipment, access, sequence, and schedule the contractor plans to use. We pair structural modeling with hand calculations and field judgment, and we prepare drawings that crews can build from and that owners and agencies can review.

Our support continues after the drawings are issued. Our engineers visit the site, respond to questions from the field, and work with the contractor to adapt the design when field conditions change. When a project calls for it, we bring in GZA’s geotechnical, instrumentation, and vibration specialists, so contractors can address structural, geotechnical, and site-condition questions with one team.

Groundwater Control

Dewatering systems are often an essential component of a project's design, especially in congested urban areas which could have a significant impact on the soil condition at adjacent properties.

Pre- and Post-Construction Structural Condition Surveys

Surveys are a powerful tool to limit risk and liability when performed prior to construction activities. GZA's condition survey services combine engineering expertise with advanced reality capture technologies to document existing conditions before, during, and after construction. Using...

Pre-Bid & Value Engineering

GZA assists contractors with creative approaches to construction, strengthening your bid by providing economical and constructible solutions.

Deep Foundation Testing

GZA has been in performing non-destructive testing on both large and small deep foundations projects, both on land and offshore, since the 1960’s.

Environmental Monitoring

During construction, observation of air quality, noise, and vibration can reduce the risk of 'cease and desist' orders, support worker health and safety programs, and reduce the risk of damage to adjacent structures.
