Manning Design+Construction is experienced in residential, multi-family, and commercial seismic upgrades, at any scale. We retrofit existing structures and/or engineer seismic solutions for new development. We also modernize unreinforced masonry, upgrade rooftop structural support for green roofs (ecoroofs) and other rooftop development, and repair and replace foundations throughout the Portland, Oregon metro region.

Pacific Northwest building codes have been updated to reflect the increasing threat of seismic activity that is predicted for our region. Manning Design+Construction can help you navigate the latest building codes and permit procedures as well as the design, engineering and building process to ensure your Portland business or residence is ready when anticipated earthquake activity occurs.

Damage to buildings throughout Portland during an earthquake is expected to include walls cracking, toppling chimneys and masonry, and buildings shifting off of their foundations. Older buildings and homes are especially vulnerable to these forces as they often lack seismic anchoring to their foundations and were not engineered to resist the shaking and movement that is anticipated from a major earthquake. We can help you identify potential hazards ahead of time and engineer and implement solutions to help mitigate damages and the danger of serious injury or losses from a seismic event in the Portland, Oregon region.

If you have concerns about the seismic readiness of your home or business in the Portland area, including Multnomah, Clackamas and Washington Counties and beyond, contact us to discover how we can help you fortify and ready the safety and livability of your building in light of our uncertain seismic future.
