Through the Operational Projects Unit (OPU), “technical support is provided through crime scene survey, crime scene documentation, demonstrative court presentation, three-dimensional physical models, and crime scene photography” (“Crime Scene Documentation”, n.d.). The role of the Evidence Response Team Unit (ERTU) is to, “provide traditional and hazardous evidence collection capabilities to the FBI field Evidence Response Teams (ERTs), Hazardous Evidence Response Teams (HERTs), Hazardous Evidence Response Components (HERCs), Underwater Search and Evidence Response Teams (USERTs), and law enforcement partners” (“Evidence Response Team”, n.d.). The purpose of the Terrorist Explosive Device Analytical Center (TEDAC) is to “receive, fully analyze, and exploit all terrorist improvised explosive devices, of interest of the United States” (“Terrorist Explosive Device Analytical Center (TEDAC)”, n.d.). Through the Counterterrorism and Forensic Science Research Unit

No matter how handy you may be with the power tools, there will come a time when you will need to hire the services of a general contractor. Sure you may pride yourself on your ability to handle even the most complex building tasks or your complete collection of shiny, well maintained tools. But if you are like most homeowners, you will eventually come across a construction or renovation job that is simply beyond your-or your toolbox's-capabilities. It is during these very occasions that you will need a general contractor.

At 9:03 a.m. a massive bomb resting inside a rented Ryder truck destroyed half of the nine story federal building in downtown Oklahoma City. It also claimed the lives of 169 men, women, and children, while injuring hundreds

While hijacked airplanes on 9/11 caused the most fatalities of any single terrorist incident, the majority of terrorist attacks are carried out by conventional explosives and secondary devices. This is a broad category that includes incendiary devices, pressure bombs, car bombs, and any other explosive device. These weapons are low cost, low tech, and easy to construct. Out of the five CBRNE categories, explosives are by far the most likely hazard to be encountered (FEMA,

Timothy McVeigh packed a Ryder truck full of five thousand pounds of explosives. These explosives were made out of fertilizer. He parked the truck in front of the Alfred P. Murrah Federal Building. He lit a five minute fuse when he parked the truck, and he left. He was about six blocks from the building when the explosion happened. The explosion destroyed a nine story concrete and granite building. It also destroyed or damaged nearly 300 nearby buildings, and completely destroyed the vehicles across the street. People in the building survived by diving underneath their desks. This explosion could be felt up to fifty five miles away.

Thirty people were killed instantly. Eight later died from their injuries and hundreds of others were injured. A majority of the persons killed were messengers making deliveries, stenographers, clerks, and brokers (Gross, 2001).The blast was so strong it sent debris soaring as high as 34 floors and derailed a street car one block over(Andrews, 2014). Buildings shook as their large windows burst inwards. Luckily, most of the occupants inside were spared

No steel-beam high-rise had ever before (or since) completely collapsed due to fires! However, such complete and nearly symmetrical collapses in tall steel-frame buildings have occurred many times before—all of them due to pre-positioned explosives in a procedure called “implosion” or controlled demolition.

The construction of the Skyline Plaza in Fairfax County came to a halt early in the afternoon on March 2, 1973. It was originally speculated by the workers on site that the crane assisting in lifting materials to the higher sections of the building failed and fell into the side of the building causing the collapse. However, Author Dov Kaminetsky conducted research alongside the National Bereau of Standards(NBS), and published his book, Design and Construction: Lessons from Forensic Investigations.[2] Kaminetsky provides the conclusion of NBS 's investigation that the collapse was a result of shear construction error. The building began to collapse as construction workers proceeded to remove the concrete shoring between the middle sector of the building, specifically the 22nd and 23rd floor. The shoring process requires the placement of a concrete structure to support a building while under construction to prevent the collapse of the operation. The result of the collapse took the lives of 14 construction workers and 35 other individuals near the building. With proper critique to policies and evaluation of work orders, further disasters may be prevented in the future in the United States. So how did theinvestigationn of the

At 9:02 a.m. CST, a rental truck filled with explosives is detonated outside the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma. It was all planned by two former US army soldiers Timothy McVeigh, and Terry Nichols. Approximately, 500 people were injured, 168 people were dead including 19 children who were in the daycare of the building. This bombing shook the whole country. Luckily, the Army veteran Timothy McVeigh is arrested in a traffic stop because he got caught driving a car without license plate.

I personally think that the closest real world example that could relate to this incident is 9/11. Minus the fact that it was a terrorist attack and could possibly have been an inside job, it is another example of a surprise attack that occurred with out warning that killed about 3,000 people and injured 6,000 more. It also had the effect of collateral damage because when the buildings collapsed, chunks of steal rebar and concrete fell crushing people.

In the early days, explosive users would light a fuse, to which the flame would travel down the fuse to powder lying within the explosive, resulting in a combustion of released gasses from the burning gunpowder. Gunpowder then was used for stationary explosives such as TNT, its use being to blast rocks to break through mountains, paving the way for roads to be built and laying down the foundation for the future. Gunpowder’s “vehement nature” led to the search and discovery of other explosives, ones that didn’t share gunpowder’s unstable explosions and heavy smoke

The FEMA document focuses on numerous different ways to minimize damage by car bombs to buildings. The publication focuses on site design for buildings at high risk of car bombs, because they have the capacity for maximum damage and casualties. There are design alternatives, such as re-alignment of the approach to buildings that slows down vehicles and providing adequate stand-off distance between bomb vehicles and the buildings to reduce impact. Car Bombs require a different set of mitigation measures that often require modifications to buildings.

As mentioned earlier individuals looking to cause destruction among the local population coupled with the basic knowledge of explosives can create a device to create such a weapon. The construction of a dirty bomb can be as simple as combining an explosive component, a fuse, screws and or nails along with the radioactive material all enclosed in a case.

Barnes Wallis, also British, designed what was called an Earthquake Bomb. This was a bomb that fell from high above the earth, penetrated the ground, exploded, and caused an earthquake. It was used towards the end of the war, on massively reinforced installations, underground caverns, buried tunnels, and bridges. Some of Wallis’ bombs based on the Earthquake Bomb were used to disable the German V2 factory, bury V3 guns, sink Tirpitz, the battleship, and other previously undamageable targets.

Construction Management is the overall planning, outlook, coordination, budget and control of a construction project from start to finish. Without them, construction projects would be very unorganized and chaotic. They make sure projects run smoothly and efficiently. They work with electricians, plumbers, carpenters and general contractors to produce the safest and best way to complete the project for the customer. Being a construction manager is a good job because they help many people build what they need.
