Two killed, one badly hurt in New York crane collapseMay 31, 2008 - 11:43AM
A crane crashed onto a building in New York City, killing two construction workers and seriously injuring another, officials said, in the second such fatal accident here in less than three months.Mayor Michael Bloomberg called the incident was "intolerable," but said there was "no reason to think there's any real connection" between the two crane crashes.All three victims were working on the site in the Upper East Side of Manhattan Friday when the crane fell on the 32-story building being built and a 23-story building across the street, the mayor told reporters, adding that a pedestrian was also lightly injured.Police said the crane operator died at the scene, while a second worker died later in hospital. A third worker was in serious condition with a chest wound."I think what has happened is unacceptable and intolerable," Bloomberg said."Having said that, we do not at the moment know exactly what happened or why... whether or not had we had other regulations, we could have prevented this at this point, we just don't know."Officials insisted the crane had been properly inspected."We have no reason to believe that there was anything we could have done to prevent this. Clearly, the crane fell. Three people were very badly hurt, one fatally, so we have to take a look at our procedures again," Bloomberg said.New York Governor David Paterson said the accident was a "terrible tragedy," adding: "There's no need to speculate now on how this happened. That will all be investigated, but certainly these types of accidents are all too frequent."A similar tragedy took place in Manhattan in March when a construction crane fell on top of a small building, killing seven people.New regulations were introduced following the March accident, and first deputy buildings commissioner Robert LiMandri said the crane involved in Friday's collapse had been inspected under this new protocol.Firefighters picked through piles of rubble at the site, while crowds gathered trying to get a look at the twisted metal of the crane and part of the building that appeared sheared off.In March, seven people were killed, six of them construction workers, when a 60-meter (200-foot) crane collapsed and crushed an entire residential building and damaged several other properties.Bloomberg said at the time that the accident was "one of the worst the city has had."A New York city employee later was charged with lying about an inspection he supposedly made of that construction crane.That building under construction, a 43-story residential block, had been cited for 13 safety violations, five of which were still outstanding, according to local authorities.

Research

This my element that i chose, 2 beams being connected together to make the apex and a mullion below that connection to withstand and work with the building against wind loads.
This is a crane on site helping erected the steel members, the crane would stay onsite from the very first erection of steel to the very last.
This is another view of all the steel members, and another look at my element for my major project.
And this is my delivery truck that i used on my poster! I had engneers designs of my construction as well as steel fabricators drawings which i added to my poster but for some reason i cannot upload them.

Task 5.

H. TROON

More images of bondek and the pillars that are spaced to support the above flooring.
This building is going to be a 5 star rating buliding so they have installed a tank which will then supply the bulding with their own water.
This is the undercover parking, here is the 'bondeck' type material that supports the flooring above. A concrete pillar supporting the florring above as well.
A box gutter, drainage system, which is supported by a steel connection which is bolted into the pre-cast concrete panels


Close up of the connection of the pre-cast concrete panels, they are bolted together and then a mastic type material also is in place to allow some movement.
This picture shows the services, eg air conditioning, electrical in the roof and after all these services have been installed plasterboard will cover the ceiling and the services
Here is a pipe that is being held up by a type of string to the 'C' purlins in the roof. Also a beam with bracing coming off it.

This is a close up of the connection between the pre-cast concrete panels, this is a mastic type material that alllows some movement.
A close up of the connection of steel to the concrete, this is supporting the 'C' purlins in the roof.
Here you can see the beam cast into the pre-cast wall with the addition of a bolted connection. There is also secondary beams spanning from the primary beam. There is also very heavy bracing to support the primary beam. Also visible is the services.
Here is a pre-cast concrete wall, with steel bolted and welded connection, there is also a beam bolter in to the wall. This wasll is load bearing, which is giving support for the roofing and the long spanning of the roof with the beams.
Tilt your head to the LEFT this is pre-cast concrete, the supporting beams have been taken out and you can see that it has been patched up. There is no structual load on these walls, they are their for asthetics only.
H. TROON is the construction company that have been contracted to build this office block for the Department of Health in Ballarat, Armstrong St North.
Here are the lovely subcontractors just finishing rendering the supporting posts for the enterance of the building. The concrete that you can see is all prefacbricated and brought to site.
Another enterance to the buliding, their are two office spaces on for the department of health and the other will be put up for lease. The concrete doesnt take the load it is just their for asthetics.
Below is a conection between two steel beams, stiffing and a column to support, along woth bracing. Bolted connection between all the steel components

Task 4.

Task 3.

Palmer Brothers Eng. Details

This detail show the site plan; where the portal frame construction is situated on the site.
This is the roofing detail. Bracing, 'C' purlins, beams.
This the the floor plan, you can see the columns and their spacing, to give the open span. Also the entrances and exits are visible.
This is just the site elevations of the portal frame construction of Palmer Brothers. This is a detail of the elevations from the front entrance an the rear.
This is a detail drawing of a portal frame construction. What you can see is the column and beam connection, footing details, the wall and roofing materials used.
