electrical infrared inspections

Electrical Infrared Inspections

Infrared inspections.

Infrared inspections find hot spots caused by defects in connections and components. Infrared electrical inspection or  thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared electrical inspection is the best diagnostic tool available for finding these hot connections in the early stages of degeneration. This is why your insurance company may have asked for an electrical infrared inspections, to find and prevent problems before they cause damage to your personnel, equipment and facility, thus reducing downtime and less repair costs to the owners, etc.

 Infrared Inspections

should be an integral part of any electrical preventive maintenance (EPM) program. This type of electrical infrared inspections can help save money by verifying equipment is operating at peak efficiency and reducing costly downtime in the event of electrical system failure. It also can help save the costs associated with the damage that a fire may cause if an electrical system overheats or fails catastrophically. This inexpensive inspection program has evolved into a valuable preventive maintenance tool. The following information discusses the benefits of infrared inspection and explains how the inspections are conducted. The heating effect continued to increase past the red, in a region that is now called infrared (“below red”). He measured radiation effects from fires, candles and stoves and deduced the similarity of light and heat. Today, devices can be designed to detect, amplify and display radiation from the visible or infrared portions of the spectrum.Using infrared for electrical infrared inspection and by using infrared technology as part of an electrical infrared inspection program works on the principle that electrical equipment normally gives off heat, but malfunctioning or overloaded electrical equipment will give off excessive heat due to increased electrical resistance. This heat can be detected with the use of infrared inspections. Using an infrared camera or video recorder, the heat can be converted to an image that can be seen and recorded for analysis. The infrared camera can display various temperatures that are being recorded and the temperature differential between “normal” and malfunctioning equipment during. The images can be used to identify exactly what equipment is affected and how serious of a problem exists based on temperatures and temperature differentials. The images can be inserted into a report to help explain the problem and any suggested repairs or improvements. Infrared should be scheduled prior to a major scheduled shutdown. This allows the greatest flexibility in resolving problems found during the inspection. Infrared inspections are a non-destruction test that should be completed during normal business operations while equipment is running at or near capacity. Equipment should run for at least one hour before inspection. There is no need for downtime or special tear-down of the equipment to perform the electrical infrared inspection. However, equipment covers must be removed to ensure effective scanning. Because busway conductors are so close to enclosures, the covers may not need to be removed during infrared inspections for electrical equipments.

Flood damage inspections

Flood Damage Inspections

Flood Damage Inspections

EMA engineers provide flood damage inspections in Jacksonville, St. Augustine, Palm Coast, Daytona beach, Ormond Beach, Melbourne, Sebastian and surrounding areas.We protect ourself and our clients from the unique challenges posed by flood damaged inspections of damaged buildings.

Hazards in and around flood damage inspections of  buildings include the risks of:

  • growth of large mold colonies;
  • septic system collapse;
  • trip-and-fall injuries;
  • structural collapse;
  • fire and explosions;
  • toxic sludge and materials containing waterborne bacteria; and
  • electrical shock hazards.
 Flood damage inspections
EMA are forensic engineers perform flood damage inspections on commercial and residential structures.

Forensic Flood Damage Inspections

  • Inspect the flood damage inspection building exterior for downed power lines and gas leaks. Gas leaks will smell like rotten eggs. If you suspect a gas leak, contact the utility company immediately.
  • While entering the building, see if the door sticks at the top. If it does, this could mean that the ceiling is ready to collapse. After you open the door, stand outside the doorway, clear of any falling debris.
  • Wear sturdy, treaded boots. According to the American Red Cross, the most common injury following a disaster is cut feet. Broken bottles, nails, glass, and other dangerous debris may litter the floor, and stairs may be very slippery.
  • Once you are inside the home, check for gas leaks again by flood damage inspections. If you smell gas or hear a blowing or hissing noise, open a window and quickly leave the building. Turn off the gas at the outside main valve, if you can, and call the gas company from a neighbor’s home. If you turn off the gas for any reason, a professional must turn it back on. Never use an open flame inside of a flood-damaged house unless you know that the gas has been turned off and the house is ventilated. To inspect for damage, use a battery-powered lantern or flashlight, and not an open flame or electrical fixture in the house.
  • Do not use appliances that may have gotten wet unless you know they have been dismantled, cleaned and dried.
  • Do not work by yourself during flood damage inspections. If you are injured, it might take a long time before you receive assistance. If you must work alone, bring a cell phone or radio so you may call for assistance, if the need arises.
  • Bring a HEPA-rated respirator to use in case you detect extensive mold. If you are asthmatic or otherwise at heightened risk to mold exposure, leave the building. Other inspector-safety equipment, such as gloves and coveralls, may also prevent contact with mold and other contaminants.
  • Florida Flood damage Inspections

  • Examine doors, walls, windows, floors and staircases to make sure that the flood damage inspections of  building shows no signs of potential collapse. Inspect for loose plaster, drywall, and ceilings that may fall. Also, inspect the foundation for evidence of cracks and other structural damage that may render the building uninhabitable.
  • Inspect for fire hazards, such as broken and leaking gas lines, flood damage inspections electrical circuits, and submerged furnaces and electrical appliances. Flammable and explosive materials may travel from upstream. Be aware that fire is the most frequent hazard in homes following floods.
  • Inspect for electrical system damage, such as broken and frayed wires, and burned insulation. You can turn off the electricity at the main fuse box or circuit breaker. If you have to step in water to get to the fuse box or circuit breaker, call an electrician first for advice. Electrical equipment should be inspected by a qualified professional and dried before being returned to service.
  • Inspect for sewage and water supply-line damage. If you suspect sewage lines during flood damage inspections have been damaged, avoid using the toilets and instruct the client to call a plumber before using flood damage inspections. If water pipes are damaged, instruct the client to contact the water utility company and avoid operating the tap.
  • Use caution while inspecting crawlspaces for a variety of reasons, such as the presence of mold, sewage, asbestos, chemicals, rodents, and the risk of structural collapse.
  • Watch out for animals, especially poisonous snakes, which may have been washed into the building during the flood. You can use a stick to poke through debris to check for dangerous critters.

Concrete GPR EMBEDDED ELECTRICAL SERVICES

When core drilling or saw cutting in commercial and industrial locations is needed, accurate detection of electrical conduits is essential for preventing safety risks, power outages and costly damages. Concrete GPR Scan  for PT Cables Daytona provides two specific but different scanning services in this area: Elevated concrete slab scanning and concrete slab-on-grade locating. Elevated concrete slab scanning involves detecting embedded electrical conduits prior to core drilling a hole through the slab.

Concrete Xray in Tampa

Concrete slab-on-grade locating – a concrete slab poured directly over dirt – involves scanning a trench line for conduits before conducting saw cutting and trenching to install a sanitary pipe, water line or something similar. [See diagram No. 2]

CONCRETE GPR ASSESSMENT

Also crucial in the Concrete Xray Scan Daytona imaging process is determining what’s in the concrete structure. This includes gauging the concrete thickness, what the rebar content is, its spacing and its elevation within the slab. This extensive, critical information helps our clients and their teams to understand the makeup of the concrete. we also can determine concrete covers over the rebar using state of the art equipment.

VOIDS DETECTION AND LOCATIONS

We can also locate voids – air gaps between the sub-grade, dirt and the concrete slab-on- grade – hidden below concrete or asphalt surfaces. This degradation occurs over time due to compaction, pipe ruptures or erosion but is often undetectable on the surface. EMA Concrete Xray ground penetrating radar can help our clients locate these areas and – most important – avoid collapses.

While GPR does not determine what type of object is being located project managers are experienced at using all available data in identifying the type of reinforcing steel or electrical conduit present.

The photo to the left shows a typical post tension cable mark out. Using GPR and other data, we are able to locate all of the reinforcing steel anomalies. We then mark the findings on the concrete and, based on the pattern, are quickly able to determine what each marking indicates. Most often, when something is on an angle through a square layout it will be a conduit. You will have a typical rebar pattern with 12-to-18 inch centers. Post tension cables tend to be spaced further apart, depending on the building’s design and whether they are banded or uniform tendons.

COST OF CONCRETE GPR
Concrete rebar GPR testings are less expensive than XRAY due to its accuracy. The equipment is more expensive and a minimum of 2 operators is needed at all times. As a rule of thumb, concrete x-ray will cost double the hourly rate of GPR – although pricing by image may be more attractive for both parties. $150-$170 per image is fairly standard, combined with a mobilization charge of several hundred dollars. Night and weekend work is charged at 1.5 times standard rates which can lead to overtime rates too.

Protection from radiation is an important aspect of industrial radiography. The International Atomic Energy Authority (IAEA) had developed basic safety guidelines regarding the practice.

Roof Inspection Service is recognized by the roofing industry as a vital component of successful Roof Construction Management. Many vital areas of a roof installation are not visible for inspection upon completion and many times are already covered over before periodic site inspections can be made.

Full-time Quality Roof Inspection provides a set of ‘eyes’ during all phases of the installation. Critical areas such as fastening patterns of underlying insulation, mopping techniques, or glue application and drying times can be monitored for compliance with the contract documents and manufacturer’s standards.

Count On EMA Trained Roof Inspections

EMA’s roof inspections by PE engineers provide extensive experience  to observe all phases of a roof installation to ensure materials are in compliance with project documents. Prior to the start of work, our inspectors are provided specifications, drawings, shop drawings and submittals. The inspector’s attendance at the Pre-Job Conference with respective contractual parties allows a thorough understanding of the system installation, set-up areas and anticipated internal disruptions. The inspector generates Daily Roof Inspection Reports which delineates material and installation compliance, and documents any unforeseen contingent items to the contract. Non-compliance issues are immediately addressed with the roofing contractor, design professional or building owner to ensure proper installation of the specified roofing assembly.

The roof and roofing system are checked as part of a Professional Engineer’s roof inspection. The roof keeps rain and other weather elements out of the home or building. The Professional Engineer evaluates the general condition of the roof during roof inspection and estimates the remaining life on the roof. Evidence of past or present roof leakage is also assessed. The engineering report includes an expense analysis of any upcoming roof repair or replacement costs.

Most roofs are made of either asphalt, cedar, slate, or clay tile. If a building has a pitched roof, the roof can be viewed from the site. (It is not advisable to climb onto this type of roof during roof inspections  as a means of checking it. Climbing on the roof can damage roof shingles, especially older shingles. A leakage problem can be created simply by walking on a pitched roof surface.)

Roof Inspections by Licensed P.E

When the Professional Engineer finds that a roof leaks, needs repairs, or will soon need replacement, an analysis of the needed repairs and replacement is provided in the roof inspections report. This helps you plan for any upcoming roof replacement.

If the building has a pitched roof and an accessible attic, the Professional Engineer looks for evidence of roof leakage or damage to the sheathing. The Professional Engineer also looks for problems in the attic such as the amount of insulation present, water damage, and insufficient attic ventilation.

Some roof inspections advocate walking on pitched asphalt, slate, and terracotta tile roofs. There are Inspectors who lift asphalt roof shingles to determine how they were installed. This damages the roof. The slates, cedar shingles, or terracotta tiles suffer damage that can causes leakage.

Asphalt roof shingles are self-sealing. Lifting an asphalt roof shingle damages the seal. Roofing manufacturers will void a roof warranty if they determine damage was caused by such a roof inspections on the roof.

Our Professional Engineers determine the condition of the roof by visual examination. If an Home Inspector needs to walk on the roof or lift the shingles, you should ask; Why can’t this Home Inspector determine the condition of the roof visually?  Can’t this Home Inspector see that the roof shingles are old?

In some cases, it is not possible to safely observe the roof before of during a roof inspections. If the roof is not visible, we us available satellite images of the roof to assess the roof inspections. This includes historical satellite images, which can allow the roof history to be determined.

How to Inspect Roof Types

The first protection any house has against the elements is the roof and there are a variety of roofing materials. You can learn a few basics about each material that will help you spot damage that needs to be repaired or roofing that should be replaced as reported in roof inspections.

Asphalt Roofing

shingle roof inspections

Asphalt roofing surfaces are granular. When asphalt shingles age they become brittle from the sun and other elements. Then the granules can detach from the shingles. Check in the gutters and at the end of the downspouts for asphalt granule deposits. Inspect the roof for spots that look bare where all the granules have detached and been washed away. Also inspect for missing, torn or warped shingles. When the edges or corners of shingles are rising or curling, they have outlived their usefulness and will need replacing. Also look for indentations or punctures from hail damage. This can be far more costly than simply adding shingles so knowing how many layers are on the roof and the legal limitations can be valuable. You can commonly determine how many layers are present by examining the edge of the roof during roof inspections.

Metal Roof Inspections

Metal roofs are commonly steel, copper, aluminum, or galvanized iron. Most metal roofs have a life expectancy of about 50 years. Perforations, pits, rust, or corrosion can help determine the age of the roof. Check the seams, corners, and joints for loose, dried out, or peeling caulk or other seam material while performing roof inspections.

Slate or Clay Tile Roof Inspections

tile roof inspections
ema structural engineers tile roof inspections

Roof Inspections of 3 most common tile roof materials and these are concrete tile, clay or terracotta tile, and composite or light weight tiles. The most common tile is made of concrete and you can identify these roofs by the thickness and absence of color on the bottom or underside of the tiles. They often have 75 years or lifetime warranties. However they can leak sooner depending on the quality of workmanship. Local codes and the area of the country will require these tiles be attached with nails, construction adhesives, battens, screws, foam, or a combination of fasteners noted during roof inspections.

roof inspection for tiled roofs

Composite tile roof inspections are not as popular and are made to resemble clay tile. They are principally installed on homes that lack the structural ability to hold much heavier concrete. Composite tiles also cost less to install.

Clay tile roof inspections comes in two types: terracotta and sand cast. Terracotta tile look just like the material of clay flower pots. Sand cast tiles come in different colors noted during roof inspections.

Slate and clay tile roofs and even cement shingles are designed to last as long as the structure when cared for properly. However they can be broken by hail, ice, or by walking on them. Avoid walking on these materials and use a drone or binoculars to look for any missing tiles or ones that are chipped or broken roof inspections.

Wooden Shakes or Shingles roof inspections

wood shake roof inspections

This is another roofing material you should not be walking on. Inspect these roofs from a ladder, with binoculars or a drone camera. Wooden shakes are split by hand, and wood shingles are sawed and tapered. Weather will deteriorate wood shakes and shingles over time. See if there are missing rotted, warped, or broken shingles or shakes. As a general rule of thumb if a third or more of these roofs are damaged, the whole roof needs replacement.
