The first truck arrives, with traffic halted as it moves through the intersection. This girder is 8 feet high and 127 feet long. Yikes!
First responders from across the country were in Virginia Beach for a massive structural collapse training exercise hosted by the Virginia Beach Fire Department and Virginia Task Force 2. The annual School was held at the sprawling complex of crawl spaces and staged disaster zones representing different scenarios – things first responders have seen and experienced first-hand. This course gives urban search and rescue teams a chance to practice their skills. More than 160 people took part in the hands-on training lasting for 8 days with students coming from as far as San Francisco, California, Texas, Pennsylvania, Ohio, Delaware.

the floor was rather spongy in this area. Years of a failing roof have cause irreversible damage to the beam supporting the roof and the floor below
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.

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:

This golf course in Golden, Colorado was built at the site of an old clay mining operation. Soft clay horizons occurred between hard sandstone intervals of the Laramie Formation. The beds here are vertically oriented - structural tilting occurred during the Laramide Orogeny in the Tertiary. The Laramie Formation is a nonmarine, coastal plain to deltaic succession of mostly mixed siliciclastic sedimentary rocks - sandstones, siltstones, claystones, and coals.
After clay mining ceased, the site became a landfill for ash from coal burning operations. Landfill activity buried many dinosaur footprints preserved in the Laramie Formation sandstones. The locality is now an odd-looking golf course, but portions of the site are a "fossil preserve" with dinosaur footprints, plant fossils, and other features that can be closely examined along trails.

Clay Mining
Since 1877, five generations of the Parfet Family have mined clay from this area. Previously operated as the Parfet Clay Pit, the ceramic and brick industry used clay from this area primarily for bricks and sewer pipe. The Governor’s mansion, East and South High Schools in Denver, and the Jefferson County Hall of Justice in Golden were built from the distinctive tan bricks.
The clay, deposited in lakes and swamps 68 million years ago during the Late Cretaceous, is part of the Laramie Formation. Uplift of the modern day Rocky Mountains some 67-55 million years ago tilted the rock strata to their near vertical position. The clay layers were excavataed as trenches, leaving the vertical fins of sandstone visible today. Trace fossils such as dinosaur tracks and leaf impressions are visible on many of the remaining sandstone walls. The pits on either side of the trail contain fossil footprints that have yet to be detailed.
Logs, wedged horizontally between the sandstone walls, served as a warning device to miners. If the walls started to give way, the miners would hear the logs creak or “sing” and move to safety.

Clay Mining
Clay from the Fossil Trace Golf Course, previously operated as the Parfet Clay Pits, has been mined for the ceramic and brick industries since 1877 by five generations of the Parfet family. The predominant uses of this clay were for brick and sewer pipe. The tan brick was used to build the Governor’s mansion, East and South High Schools in Denver and the Jefferson County Hall of Justice in Golden. The clay was deposited in small ponds and depressions about 70 million years ago in the Late Cretaceous period and became part of the Laramie Formation. The rock strata were tilted vertical by the uplift of the modern day Rocky Mountains to the west approximately 60-65 million years ago. Clay layers were excavated as trenches, leaving vertical fins of sandstone, which contain trace fossils. The sandstone was originally sand which was deposited when adjacent streams overflowed their banks during flood events.

I spent a little time shooting anything which grabbed my attention at the new Troy, Michigan (TRM) station this afternoon. Some of the structural elements (like this) did get my attention.
