-Window lintels are generally arched, but there may be straight lintels over windows with URM. National Development Council has provided their final report to the City on URM retrofit funding. -Bricks are not uniformly laid, or the mortar running between them is white and/or easy to peel away with your fingers. Unreinforced masonry walls are a thing of the past. This in-depth analysis is beyond the scope of what the City could do in our validation efforts. It is more difficult to tell if a concrete or concrete block building includes reinforcing steel. Requiring retrofits for URMs means that more of these “character buildings” may be preserved after an earthquake. You can also consult with a licensed engineer or masonry expert to determine if your home is unreinforced or not. On August 3, 2017, we released the URM Policy Committee's final recommendations. In previous earthquakes, unreinforced buildings have fallen apart within only seconds of ground movement. We would like to encourage owners to go beyond minimum code for seismic retrofit. In 2016, the Seattle Times ran a story, “Buildings that kill: The earthquake danger lawmakers have ignored for decades”. The Office of Emergency Management led this effort, and arranged meetings with community leaders, banking institutions, developers, real estate professionals, and historic preservation groups. -Walls falling or buckling, resulting in structural damage as well as damage to surrounding structures or even people. Earthquakes are the greatest risk to unreinforced buildings, and earthquakes do occur in the Toronto area. The National Development Council has provided their final report to the City on URM retrofit funding. Most of the time, the mortar used to hold bricks together is not strong enough to withstand much impact or ground movement without additional masonry elements. Dennis Pradere, P.E., S.E. Unreinforced masonry buildings are more likely to crumble and collapse in an earthquake. The Seattle Department of Construction & Inspections issues land use, construction, and trade permits, conducts construction- and housing-related inspections, ensures compliance with our codes, and regulates rental rules. If you cannot tell by looking at the outside of your building, go to the electrical outlet box. Parts of the building may also collapse onto nearby people or structures. With the completion of this report, along with the recommendations of the URM Policy Committee, the City will begin developing high-level policy recommendations for the Mayor's Office to review An unreinforced masonry building has load bearing walls and non-load bearing walls, but reinforcing material, such as concrete, cinderblock or rebar, supports neither.

FEMA P-774: Unreinforced Masonry Buildings and Earthquakes 1 1 Introduction This document provides guidance on how to develop programs to reduce the earthquake risks of existing unreinforced masonry buildings. 700 5th Ave, Suite 2000, Seattle, WA, 98104
We have posted the updated list of URMs on the Project Documents page. If every row of bricks looks the same, the building may be reinforced. Or are they? As a result, your home becomes stronger, more valuable and better able to withstand earthquakes. Contact Turnbull Masonry to discuss your options for reinforcing masonry homes, offices or other structures. (See the Project Documents page for the full report.). We updated the list quarterly to reflect the results of appeals and demolitions. The City WILL NOT INSPECT any site that does not follow these requirements. Help prevent the spread of COVID-19 in King County. Oftentimes, the walls on the second floor or other part of the building collapse, leading to complete collapse of the entire building. Simply looking at the exterior of your home or building can often tell you if it’s reinforced or not. An unreinforced masonry building has load bearing walls and non-load bearing walls, but reinforcing material, such as concrete, cinderblock or rebar, supports neither. If a building remains unreinforced, it’s at risk for collapsing walls and “peeling” of masonry elements. However, there are also concerns about maintaining important buildings that are the heart of the historic and cultural character of many neighborhoods. The City of Seattle has issued requirements for construction projects seeking inspections. It may also result in less building demolition or vacancy. King County has approval from the State Department of Health to allow all private construction activities that are low-risk and adhere to strict COVID 19 Job site Requirements. All building owners have the right to appeal the determination of URM building status. We anticipate that the program will have tools and incentives to help building owners. Make sure the power is turned off before removing the cover plate. Senior Structural Plans Engineer(206) firstname.lastname@example.org, Address:
As a result, URM is not as sturdy and remains at greater risk for partial or complete collapse in an earthquake. Renovation beyond the code requirements increases the potential for buildings to be quickly occupied after an earthquake. If the structure was built prior to 1940, there’s a much greater risk that it is not reinforced. Solutions to reinforcing masonry include adding a steel frame that is bolted to the wall or tying the walls to the floor and roof. These rows of bricks turned endways every 5-6 rows provide added stability to unreinforced masonry. While it’s not cheap to add reinforcement, it’s even more expensive to fix a home with damaged walls. Phone Alt: Violation Complaint Line: (206) 615-0808. Tuck Pointing, Brick and Chimney Repair Toronto | Turnbull Masonry Ltd. Earthquakes are the greatest risk to unreinforced buildings, and earthquakes do occur in the Toronto area. Take a look at your building and see if you have “header courses” of bricks. Unreinforced masonry walls, also known as URMs, are lacking steel reinforcing bars embedded inside, which add a lot of strength to the structure of a building. With the completion of this report, along with the recommendations of the URM Policy Committee, the City will begin developing high-level policy recommendations for the Mayor's Office to review. In the Fall of 2018, a group of interested private and non-profit sector organizations convened a separate effort to develop recommendations to implement a URM retrofit policy. As the fol-lowing chapters will show, this building type is typically the most seismically They would be if we (at AtlantisFiber™) had any influence on building codes. These bricks will be facing end out, as opposed to side out. Looking at the building from the outside, you’ll see that the end brick, or particular rows of bricks, are facing a different direction than the majority of bricks. Please see the Timeline for our future actions. Retrofiting brick buildings to meet current codes can protect public safety, preserve historical buildings, and help Seattle recover faster after an earthquake. -Every four to seven rows of brick are followed by a king row, or a row that is designed to provide additional strength. If you remain unsure, consult with your local Building Department to see if the original plans for your home are on file. Once the policy is adopted and legislation approved, we will develop a program to require owners to retrofit their URM buildings. Unreinforced masonry is typically made of bricks, hollow clay tiles, stone, concrete blocks or adobe. P.O. Phone: (206) 684-8600
SDCI customer service areas remain closed until further notice and continue offering services online. Even relatively light shaking can trigger crumbling debris and further damage. We currently only require seismic upgrades when an owner is doing a large remodel to a building. Public safety is the primary reason for requiring retrofits of URMs. In the winter and spring of 2018, the City worked with stakeholders to investigate financing and funding options for owners of URMs. The upgrades typically do not bring the URMs up to current code, but they do help stabilize the buildings enough to make them less vulnerable to collapse during earthquakes. Retrofits can help lessen damage to these buildings, allowing businesses to reopen in a timely manner following a smaller earthquake; a City’s resiliency is key to recovery.

Unreinforced masonry can be reinforced with proper masonry techniques. Find out more at King County Public Health. We specialize in historic restorations, so you can rest assured the value of your historic building remains fully intact. It’s actually against most local building codes to construct unreinforced masonry.
