Controlled demolition requires careful planning based on thoughtful engineering. Our professionals develop highly accurate models of structural behavior to assess and reduce vulnerability and risk during implosion, deconstruction or dismantlement.
We help demolition contractors by providing engineering reviews, calculating debris footprints, analyzing stresses and vibrations, and helping to develop safe and efficient demolition scenarios and logistics plans.
The Four Ds: Demolition, Deconstruction, Dismantling . . . and Design
Understanding how every part of a structure will behave is the key to safe, successful deconstruction. Our design experience – in buildings and bridges of every type and size – has yielded a deep understanding of the properties of and interactions among building elements. This knowledge provides useful insights into the demolition process, especially when a structure has unusual geometries, materials or loads.
More than Just Buildings: Bridge Demolition Engineering
Our specialists in Transportation and Infrastructure design provide support for the deconstruction of concrete and steel bridges. We evaluate planned demolition sequences to confirm stability during superstructure removal. Our engineers perform detailed inspections and build models that account for in situ conditions. Using these models, we develop cutting and removal sequences that factor in calculated loads at every step of the way to avoid unplanned movement or collapses – and protect nearby structures from collateral damage.
We offer a range of other specialized deconstruction services for bridges.
- Design for containment structures that limit the impact of blasts used for pier removal
- Development procedures for temporary sheeting or cofferdam removal
- Stress and deformation analysis for portions of bridges retained after demolition
- Planning for site-condition and groundwater level restoration
