Construction and Demolition Engineering

GZA provides construction engineering services for contractors, owners, and project teams constructing, rehabilitating, or removing bridges, buildings, waterfront facilities, and other complex structures. Our services include temporary works, demolition engineering, erection planning, shoring design, scaffold design, rigging design, engineered lift plans, concrete formwork design, bridge falsework design, and structural load analysis. With Siefert Associates now part of GZA, our team brings decades of contractor-focused construction engineering experience to projects throughout the Northeast and other regions.

GZA’s construction engineers develop temporary works and construction procedures based on the structure, proposed equipment, site access, anticipated sequence, and project schedule. Our construction engineering services support heavy civil, transportation, industrial, commercial, waterfront, and building projects involving new construction, rehabilitation, staged construction, and demolition.

Our engineers prepare demolition plans, erection procedures, staged construction analyses, shoring design, temporary bracing during construction, engineered lift plans, rigging design, and lifting device design. Structural modeling, including finite element modeling, can be combined with engineering calculations and documented field information to evaluate temporary and permanent structural loading during construction.

Depending on the defined project scope, construction-phase services can include site visits, responses to contractor questions, and evaluation of design modifications associated with documented field conditions. GZA can also coordinate geotechnical engineering, instrumentation and monitoring services, vibration monitoring, groundwater management, and other related disciplines through an integrated project 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-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.
