RAF MILDENHALL, England -- Firefighters from the 100th Civil Engineer Squadron Fire Department prepare an exercise scenario on the second floor of the structural trainer here Feb. 20, 2013. The firefighters train regularly on structural, aircraft and compartmental fires to ensure a quick and effective response in real-world situations.

All of the girders and knuckles are fabricated for a specific location on the bridge and when brought on site they are placed in their specific location because nobody wants to move them twice.
Now the girder can be held fully vertical, supported by the two remaining brackets and it is ready to be moved into the vertical storage location.
Crew members prepare to set steel girders near the Western Reserve Fire Museum and Education Center on May 10, 2012.
Once the clamp is set onto the beam, it is carefully measured to be sure it is exactly centered on the beam, then locked into place.
Dortechs Structural Silicone Glazed Curtain Wall systems can be used to create almost perfectly flush-fitted glass facades. The appearance of structural glazing is achieved by using profiles that are only visible on the room side. From the outside, only the glazing and the slender shadow joints are visible. The gap between each piece of glass is approximately 25mm (this can vary) in comparison to the 50 – 60mm site line prevalent with traditional, visible grid curtain wall systems.There are two main types of SSG system Dortech offers;
The first is based upon specialist double glazed units which are manufactured to include an SSG spacer bar which incorporates a ‘U’ channel. Typically the spacer bar will have a bronze anodised finish. Structural silicone is used to bond each piece of glass to the spacerbar. Once the curtain wall grid has been erected on site, these specialist glass units are delivered to site and locked into the grid using metal toggles which are designed specifically for each respective aluminium suppliers curtain wall system. Finally a compatible silicone is applied over the top of the vertical and horizontal joints to create a flush finish.
The second utilises traditional double glazed units manufactured with structural silicone. Aluminium carrier frames are then bonded around the perimeter of each piece of glass with structural silicone. On site, the perimeter frame is locked into the curtain wall grid and then silicone is applied over the gap between each piece of glass.
Please note, the SSG Curtain wall sysems cannot accomodate significant structural movements.
Dortech has carried out a number of projects utilising the following SSG Curtain wall systems:
Schuco FW50+SG
Schuco FW60+SG
Technal MX+SG

The ironworker signals, usually via radio, directing the crane operator where to move the girder so that it lines up with the supports.

The cathedral is located in the Cathedral Hill neighbourhood of San Francisco, California. The present cathedral replaced one (1891-1962) of the same name. The cathedral was designed by local architects John Michael Lee, Paul A. Ryan and Angus McSweeney, collaborating renown architects Pier Luigi Nervi and Pietro Belluschi — at the time, the Dean of the School of Architecture at MIT.
Its saddle roof is composed of eight segments of hyperbolic paraboloids, in such a fashion that the bottom horizontal cross section of the roof is a square and the top cross section is a cross.
In 2017, Architecture Digest named it one of the 10 most beautiful churches in the United States.
With 4 ironworkers holding onto the beam, to steady it, the crane slowly lifts it up-off the bed of the two truck units. Slow and steady is the motto for this stage of the operation.

ZEN MAGNETS - Neodymium Magnetic Balls (@1042) - Mecha Warrior v02
Video: www.youtube.com/watch?v=PNGGDpoZSZ8
v02 updated free standing structure, changed head, weapons systems on arms, weaponized arm position on right, reversed jetpack, and updated body detail.
Now I have 12 sets of my magnets tied up in the Yamato and Mecha Warrior v02 permanent builds.

This Mecha Warrior design is my Zen homage to Japanese Anime Mecha, recent Mecha suits (District9, Avatar), with a little Terminator and Star Wars thrown in. I added non-symmetric weapons systems in both arms to weaponize him with different built-in types on each side (a-la District9). He also has a Jet-pack in the center of his back along with rear facing particle projector on his backside.
The weight of the upper body proved to be a major challenge to get it to stand stable with no additional reinforcement other than the linked staggered hexagon double/triple layered hexagon stacks (same construction I used for my Water Dragon design). I used the arms to stabilize the standing frame by attaching/resting his hands on his legs. The overall weigh was distributed.
Enhancements to v02 included after adding balls and strings to various weak structural points that buckled in v01: upper hip area, lower knee area, rear section, ankle section, and back area. He is pretty solid now with the sacrifice of losing some of the details for structural security.
He is standing in a tight fit display case now ... this will be a test for magnetic strength to see if it can maintain the structure and weight over time.
I was invited to photograph at ADM Amsterdam's 18th edition of the ADM Blijft Festival, which included many bands, performers and artists as well as talks and workshops.
Here, ironworkers have attached a few of the cross braces that will eventually connect these girders. These braces keep these two girders stable, as they sit just a few feet east of Pier 13.
