Structural Engineer in Sandy, Utah
Sandy is structurally interesting because it includes several very different generations of housing. The engineer’s files include homes from the 1950s and 1970s, later homes from the 1980s and 1990s, and much newer construction farther east. That means the problems range from old concrete and unreinforced retaining walls to remodels, wind-related movement, and snow-load considerations near the foothills.
At a 1970 home near 700 East and 9000 South, the engineer inspected a stairway retaining wall that was heavily cracked and bulging inward. The wall was only about five inches thick and appeared to have little or no reinforcing steel. Decades of water exposure had pushed it inward. Rather than tear everything out, the recommended repair was to construct a new reinforced concrete wall inside the existing wall.
Another 1970s home farther south showed a different kind of problem. Cracks near the ceilings were partly related to poor attic ventilation and thermal movement, but there were also indications of structural sway. Homes from that era sometimes have less shear-wall capacity than would be expected today, so wind loads can make the structure more flexible than it should be. Additional shear-wall capacity was recommended.
In the Dimple Dell area, the engineer inspected a 1990s home where a tall exterior entry column had separated from the house by about half an inch. The problem was not foundation settlement. A connection that should have restrained the column at an intermediate level was missing or ineffective, allowing what should have behaved like several shorter structural sections to act more like one very tall, flexible member.
Older Sandy homes can have their own quirks. At a 1959 masonry home, cracking appeared at all four foundation corners because of poor consolidation of the original concrete. The engineer did not consider the condition to be a major structural failure, but repairs were recommended to protect the corners and masonry from continued deterioration.
Sandy also sits close enough to the Wasatch Front that location within the city changes the loading environment. Homes on the east side and near the foothills can see more snow than homes farther west, and drainage around sloped properties deserves additional attention.
The engineer’s Sandy files show a recurring mix of older concrete, masonry cracking, water-related retaining wall damage, remodeling, lateral stiffness issues, and foothill conditions. The age and exact part of Sandy usually provide useful clues before the inspection even begins.
Sandy has changed dramatically over the years, from its agricultural and mining roots to the beautiful neighborhoods stretching east toward Little Cottonwood Canyon. It’s a city where older rambler homes on the west side and million-dollar hillside homes on the east side can present entirely different structural conditions.
The engineer refers to Sandy often when talking about structural conditions and earthquakes. Have you ever heard of liquefaction? It turns out that when you mix sand, water and shaking, you effectively get quicksand. Homes sink, and the sinking can often result in severe damage to the home.
The engineer has seen how Sandy’s soil conditions, steep foothills, and drainage problems can affect foundations. Retaining walls and hillside stability become particularly important as you move east, while settlement and cracking are more common concerns in the established neighborhoods below. Sandy is a great place to live, but knowing which structural issues to look for, and where, can make all the difference.
