Worker killed in West Palm construction accident identified by police

Construction crews were back on scene one day after incident

The construction worker who was killed Thursday after falling from a West Palm Beach apartment project was just identified as 27-year-old Carlos Lopez Sanchez.

Sanchez fell from the 15th floor of the Alexander, an under-construction, 16-story apartment project from developers Ram Realty and Kolter Group that's expected to open next year. According to the Palm Beach Post, city police and fire rescue arrived at the site early Thursday afternoon and found Sanchez dead on the ground.

Bits of plywood and metal framework were also found scattered around the scene, the Palm Beach Post reported.

Ram deferred all questions to its general contractor, Kast Construction, whose CEO Michael Neal released this statement: "Yesterday's accident was an unfortunate tragedy and our thoughts are with Mr. Lopez's family. OSHA has conducted their initial investigation and concluded the site is safe for workers. We will continue to cooperate with OSHA's requests as they will remain on site through next week. We will keep the media informed of any important updates."

Construction workers were already back at the job site Friday morning, and a West Palm Beach police spokesperson said no foul play was suspected. However, WPTV reported that an attorney representing Sanchez's family said they feel there could have been a malfunction in his safety equipment.

The incident follows the collapse of a facade from the Alexander Lofts, another apartment building across the street that Ram also owns. [Palm Beach Post / WPTV] Sean Stewart-Muniz

Yet another tunnel based article

# data[].attributes.attachment_link.readable_text
The Gotthard Base Tunnel opened in June and will be fully operational by December, cutting the journey time from Zurich to Milan by more than an hour. The accuracy of modern tunnel construction is impressive: when the British and French tunnelling teams met in December 1990 under the English Channel, the two shafts were misaligned by less than a metre. Thanks to their skill, a rail trip from London to Brussels now takes less than two hours.

The Channel Tunnel was a magnificent engineering accomplishment. Boring tunnels from both ends makes sense: two teams boring in opposite directions simultaneously can halve the construction time. The one obvious - and essential - requirement is that the two shafts meet accurately in the centre. Modern laser-guided tunnel boring machines make this possible.

Geometric principles

Boring tunnels from both ends is nothing new. More than 2,500 years ago, a tunnel of more than a kilometre in length was constructed on the island of Samos in Greece. It was designed to serve as an aqueduct and was the first tunnel to make use of geometric principles. The engineer was Eupalinos, and the tunnel was bored under Mount Kastro to serve the ancient capital of Samos, today called Pythagoreio. The aqueduct was concealed underground to prevent enemies of the tyrant Polycrates from finding and destroying it. It served for more than 1,000 years until it fell into disuse, to be rediscovered around 1883.

Since parallel lines never meet, two shafts may fail to intersect if there is an error in position. To avoid such a catastrophe, Eupalinos arranged for the two straight shafts to zig-zag slightly near the centre point, to ensure a successful juncture even if the cuts were initially misaligned. As it turned out, the construction was so accurate that if the diggers had continued along straight lines they would have made an almost perfect connection.

Eupalinos also needed to ensure that the cuts were vertically aligned. He constructed a continuous duct, like a gutter, around the mountain between the two openings. When filled with water, this enabled him to locate the two openings at the same altitude. Similar arrangements ensured that the shafts remained horizontal as they were bored.

No one knows exactly how Eupalinos determined the directions of boring. Several methods of triangulation have been suggested. He may have set up a line of marker poles over the mountain-top between the openings. Alternatively, by laying off a series of short segments in the cardinal directions, he could determine the nett north-south and east-west displacements. The theorem of Pythagoras would then give the length of the tunnel. It would also enable the direction of the bores to be determined. Pythagoras was born in Samos around 572 BC. It is tempting to speculate that he had a role in the design of the tunnel, but we have no evidence of this.

The ancient Greeks had no laser-guided boring machines. Neither had they magnetic compasses, topographic maps or survey instruments. The tunnel was built in the sixth century BC, 200 years before the principles of geometry were formalised by Euclid.

It was one of the greatest engineering achievements of ancient times and is a testament to the power of mathematics and the ingenuity of the ancient Greeks.

We're thrilled to share incredible news from Chile today.

After a decades-long campaign, five rivers in Chile, some of them wild and scenic, have been saved from large hydroelectric dams.

The Chilean energy company Endesa announced yesterday it has relinquished all claims to the water on the Futaleufú, Puelo, Chillan, Bardón and Huechún rivers. That means that s ix hydroelectric projects, totaling 2,151 MW, have been scrapped.

The win comes after a decades-long, coordinated effort from many groups working in partnership, including Consejo de Defensa de la Patagonia (CDP), which includes International Rivers, Ecosistemas, Geute Fundacion Sur, Terram, Aysen Comité Nacional Pro Defensa de La Fauna y Flora and many others. These dams had met with strong local opposition, both because of their social and environmental impacts and the effect they would have on the tourism industry.

This is a landmark decision. In a statement, Endesa Chief Executive Valter Moro said, "Endesa Chile wants to only move forward on projects that are technically and economically viable and that are embraced by the local communities."

We commend Endesa for listening to the voices of the community and affected peoples.

Many organizations and community members have fought for years to foreground the importance of river protection and the many drawbacks of large dams. Groups including CDP, Geute Fondacion, Ecosistemas and International Rivers, among others, have kept up concerted pressure for many years on the Chilean government and on Endesa to listen to the voices of affected community members who did not want these dams.

This success would not have been possible without the win, in 2014, against the HidroAysen dams in Patagonia. That campaign helped raise the issue of river protection with the broader Chilean public, and galvanized Chilean support for protecting the country's precious natural resources.

Monti Aguirre, International Rivers' Latin America Campaign Coordinator, said, "Rivers provide drinking water, irrigation, fisheries and livelihoods for millions of people globally. We should protect them, and we need to do this in a way that is permanent and legal. Rivers have rights, and recently we've seen countries like New Zealand recognize this. In the United States, rivers have been protected since 1996 under the Wild and Scenic River Act. We welcome this great news, and we recognize that we must seize this opportunity to now secure permanent protection for the wild and scenic rivers of Patagonia."

Construction is going on at the casino near my hometown

# data[].attributes.attachment_link.readable_text
State regulators on Tuesday approved what will be upstate New York's fourth non-Indian casino, slated to go in the expanded Tioga Downs racino and harness track in the Southern Tier community of Nichols.

And while it was the fourth to get a license, the Tioga Downs casino will almost certainly be the first to open since the racino building is already in place and has been retrofitted and expanded to hold a full-service casino.

"It feels great," Tioga Downs developer Jeff Gural said after members of the state Gaming Commission approved the license.

He added that "It will really be a shot in the arm," for the struggling Southern Tier region where it is located.

Approval of the casino represents a turnaround from the original plan nearly two years ago when members of a special Location Board set up by the Gaming Commission said they believed three, rather than four casinos would work best in order to prevent the "cannibalization" of a limited gaming market.

That approach, however, provoked an outcry from Gural, a New York City real estate developer who a decade ago began building up Tioga Downs.

Joining the protests were numerous Southern Tier politicians, including the now-deceased Binghamton-area Sen. Tom Libous. They successfully convinced Gov. Andrew Cuomo to urge the Gaming Commission and its Location Board to revisit the issue and eventually open another competition for a fourth casino. Gural was the only applicant in that round of bidding for a license.

The state law approved by voters in a referendum originally allowed for four casinos upstate.

Construction on the project, which had earlier received a "yes" vote by the Location Board, has already started, Gural said. Once the Location Board gave its OK there was little doubt that Gural would be granted a license, absent some unforeseen development.

Gural said he will now try to speed up what is usually a two-month long time frame before which all the regulations allowing the casino go into effect. If that happens he said he can quickly get equipment for table games in place and have a mid-November opening. If not, he said he would likely wait until January.

Three other upstate casinos and resorts are being built from the ground up. They are: Rivers in Schenectady (to open in February), del Lago in Tyre, between Syracuse and Rochester, and Montreign near Monticello in the Catskills.
