40 YEAR STRUCTURAL INSPECTION & RECERTIFICATION?

40 Year Structural Inspection Recertification Inspections

Serving Broward, Miami-Dade, Hillsborough, Volusia and Palm Beach Counties

EMA Structural Forensic Engineers explains what a 40 year structural inspection or certification is and why it is important.

The 40 year structural inspection and recertification building inspection is required by law and is to ensure that buildings are structurally and electrically safe. Buildings must have the inspection performed by a structural engineer at 40 years of age from construction and every 10 years thereafter.

Although the cost of a Structural Inspection & Recertification can vary widely from professional to professional, there are certain basic items that can affect the cost.  Either way, it is a good idea to understand what these potential issues are so you can discuss these with your engineer.  Your engineer can provide you with a proposal once he has a good understanding of your building.  Some engineers  provide a price per condominium. Prices can range between $150 per door to $450 per condominium (depending on many factors).  Others provide a price based on square footage.  Still others take into consideration the location or the structure, its age, and even if it has a crawl space that he may have to squeeze into

settlement crack evaluation

Settlement Crack Evaluation

Building Settlement Crack Evaluations

The settlement crack evaluation in foundation walls are important as the wall are connected to the top of the footings and transferring major structural loads. The purpose of a foundation is to carry the weight of the house structure down through the foundation to the footings.

Whatever their construction, (concrete, brick, concrete blocks, etc.), foundation walls crack because of lateral force, settling, heaving or uneven loads (more weight than designed on a specific section of the foundation), of the foundation walls. Natural forces such as earth quakes can also be a contributor in earthquake regions.

Building settlement crack evaluations start with a pad and pencil.  Make notes of interior & exterior cracks and their locations. When inside the lower level, you will want to try to locate them on the inside. If the crack goes entirely through the foundation it may be a red flag. Small hair-line cracks that do not go through the foundation wall are common and nothing to worry about; they may have been caused by shrinkage of the concrete or mortar joints.

A fo crack sometimes has a similar type crack on an opposite wall of the foundation. Similar cracks on opposite walls may have the same cause, with the exception of horizontal cracking caused by a lateral force.

Types of Cracking in Settlement crack evaluation

Vertical and 45 degree cracking is usually caused by settlement and heaving. Horizontal cracking is commonly caused by side pressure on the foundation, such as hydrostatic pressure (a lateral force). Surface cracks that do not go entirely through the wall and with no signs of displacement are not normally a structural defect. Isolated vertical cracks that do not extend to the lower edge of the foundation wall are usually shrinkage cracks. They are caused by the concrete shrinking during curing.

Causes of Horizontal Cracking

The foundation should act as a retaining wall, resisting lateral pressure of the soil on the outside of the basement or crawl space. If the foundation does not provide enough lateral support, the walls will deflect inward and create horizontal cracking. Some of the causes are foundation walls that are too thin or do not have, (or not enough), reinforcement, such as rebar in the concrete foundation, backfilling the foundation too soon before the foundation has a chance to fully cure, or during back filling if big stones or hard frozen chunks of ground were dumped against the foundation .

Causes of Heaving Foundations with settlement crack evaluation

Heaving cracks in foundations made out of brick, blocks, or stones,(not concrete), will generally have cracking in the form of a step, called “step cracking”. Step cracking usually follows the mortar joints in these materials.

In concrete foundations, heaving cracks are usually vertical and are wider at the top of the crack than at the base.

Some areas of the country have expansive soils, which increase in size when they absorb water, causing heaving cracks. Moisture added to dry expansive soils, say from a sudden down pour, will drastically change the volume of the soil and cause serious heaving problems as well as structural damage as a result of a lack of  settlement crack evaluation in some cases. When the expansive soil dries, the shrinkage can also cause a pulling effect on the foundation. The method of prevention is to maintain the soil moisture content, by keeping the soil as dry as possible along the foundation. This can be achieved by proper grading around the perimeter.

Rain on Snow: A Recipe for Building Disaster

EMA Structural Engineers Explain Rain on Snow Roof Load Dangers

Rain on snow events in various counties. Structural Engineers at EMA Structural engineers, are cautioning homeowners throughout Florida, Texas, Louisiana, New york to be aware of the dangers any time there is a winter mix of snow and rain on the horizon.

Snow, followed by rain, is one of the worst combinations for roofs. The problem with rain or wet snow following a deep snowstorm is that the rainwater doesn’t pour off of the roof. It gets trapped in the snow. The increase in weight can get dramatic. Plus, the weight of snow varies depending upon the temperature and moisture content.

A 12-inch snow depth can weight from 10-lbs to 20-lbs a square foot. It’s the rain on top of this that is the real problem. This last storm probably added close to 30-lbs of snow over each square foot of roof. That’s a very large amount of weight.

Rainwater weighs approximately 5-lbs for every inch. A significant storm can cause a dramatic increase in weight on roofs that are already stressed by heavy snow and may have not been designed to handle it.

It is more of a concern for older structures. The building codes over the last three decades have done a far better job of mandating roofs to handle these types of loads. However, older cities in the Northeast have a large portion of their building stock built much earlier than that.”

We recommend that homeowners clear the snow off their roofs as soon as possible. However, he cautions that they should not go onto the roofs themselves to clean after a rain on snow event has happened.

Getting on a sloped roof with slippery ice and snow is extremely dangerous. Only remove snow from the ground with a roof rake or hire a professional with the proper insurance and safety equipment.

EMA Structural Engineers is no stranger to investigating building collapses. The firm was heavily involved in the investigation of structures after Superstorm Sandy in New York and New Jersey for FEMA and have worked on a number of insurance claims involving damage from snow.

So keep those roofs clean this winter, and avoid any unwarranted surprises!

The housing industry has proceeded at a red-hot pace for several years running. An all-time record was set in 1998, when 886,000 new-site single family homes were sold. That represented a 10% gain from the robust total of 804,000 homes sold in 1997, and an 8.1% rise from the prior record of 819,000 units in 1977. Single-family housing construction accounted for $48 million of the total $125 million generated in the industry.
