A research team has developed a platform based on building information modeling (BIM) technology for use in the design of hydropower hub buildings. The platform, called HydroBIM, combines BIM technology with geographic information systems, computer-aided engineering, internet of things, artificial intelligence, and other technologies. The HydroBIM platform provides a comprehensive approach to digital design, intelligent construction, and smart operation of hydropower engineering projects.

 

The work is published in the Journal of Intelligent Construction on July 31, 2023.

 

The BIM technology originated in the United States. Over time, it has come to be widely adopted in the water conservancy and hydropower engineering in China. Researchers have extensively studied BIM technology and the ways to be applied in the entire life cycle of water conservancy and hydropower engineering. This research has shown the significant potential in improving the efficiency and quality of engineering design, construction, and operation management in water conservancy and hydropower engineering. In recent years, researchers have explored integrating BIM across various stages of engineering, including the planning and design, construction, and operation management.

 

This research team proposes a BIM-based system architecture for digital design, intelligent construction, and intelligent operation. Their work also provides a BIM-based multi-professional forward collaborative design method and BIM-based engineering construction management model, along with a real-time safety analysis and evaluation technology system based on actual measured safety information and construction. The last piece of their work was the development of the comprehensive control platform called HydroBIM.

 

“The HydroBIM system architecture provides an integrated management and control scheme for hydropower engineering planning and design, engineering construction, and operation management. It enables the management and control of water conservancy and hydropower engineering throughout the entire life cycle under the integration of multi-system and multi-software,” says Lei Yan from PowerChina Kunming Engineering Corporation.

 

The HydroBIM series platform has been successfully implemented in over 20 water conservancy and hydropower engineering projects in China, Laos, and Indonesia. Some of these projects include the Nuozhadu Dam, Huangdeng Dam, Hongshiyan barrier lake, Dianzhong Water Diversion Project, and the Kluet-1 hydro power project. Using the HydroBIM platform, the efficiency of design and analysis for water conservancy and hydropower hub buildings has been improved by 1.5 to 2 times in terms of time, compared to conventional methods.

 

The team summarizes the HydroBIM system as “one platform, two methods, three stages, four major engineering, five in one, and six party harmony.” They explain that summary in this way. The one platform is an entire life cycle management and control platform of water conservancy and hydropower engineering with multi-system and multi-software integration. Their two methods include conventional analysis and cloud computing. The three stages include the planning and design stage, the engineering and construction stage, and the operation and management stage. The four major engineering parts include the hub project, the electromechanical project, the reservoir project, and the ecological project. The five-in-one elements include design quality, project quality, construction management, project safety, and comprehensive benefits. The last part is the six-party harmony. This includes government agencies, owner units, design units, construction control units, construction units, and manufacturing units.

 

The team built the HydroBIM system framework to cover the entire life cycle of water conservancy and hydropower engineering, allowing for complete and interdisciplinary collaborative digital design during the planning and design stage. The engineering construction management stage provides full information management and control of contracts, progress, quality, safety, and investment. In the operation management stage, the system provides integrated management of engineering safety evaluation, early warning, and emergency planning through monitoring data and consistent guidelines for positive and negative evaluations. The HydroBIM platform also allows for the integration of multi-dimensional BIM information throughout the entire engineering life cycle.

 

The team’s results show that the HydroBIM platform can significantly improve cooperation between participants, work efficiency, and information integration, while ensuring the quality and safety of the life cycle of hydropower engineering. Additionally, the potential of emerging technologies such as artificial intelligence, knowledge graphs, digital twins, virtual reality, blockchain, meta-universe, and others that could be explored in the further to continuously improve the working mode of the water conservancy industry and improve its efficiency. “Overall, the HydroBIM platform represents a promising approach to the digital transformation of hydropower engineering and has significant potential for future development and application,” said Yan.

 

The research team includes Zongliang Zhang from PowerChina Kunming Engineering Corp. Limited and Power Construction Corp. of China; Sherong Zhang and Chao Wang from Tianjin University; Zhiyong Zhao from PowerChina Kunming Engineering Corp. Limited, Yunnan Digital Water Engineering Technology Innovation Center, and Yunnan Engineering Research Center for Intelligent Construction of Water Resources and Hydropower Projects; Lei Yan from PowerChina Kunming Engineering Corp. Limited; and Han Liu from PowerChina Kunming Engineering Corp. Limited and Tianjin University.

 

The research is funded by the National Key R&D Program of China Project, Yunnan Province Science and Technology Innovation Talent Program Project, Yunnan Provincial Key R&D Program

One city held a mass passport-getting event

A New Orleans congressman organized a way for people to apply for their passports en masse.

Published

on

While the number of Americans who do not have a passport has dropped steadily from more than 80% in 1990 to just over 50% now, a lack of knowledge around passport requirements still keeps a significant portion of the population away from international travel.

Over the four years that passed since the start of covid-19, passport offices have also been dealing with significant backlog due to the high numbers of people who were looking to get a passport post-pandemic.

To deal with these concurrent issues, the U.S. State Department recently held a mass passport-getting event in the city of New Orleans. Called the "Passport Acceptance Event," the gathering was held at a local auditorium and invited residents of Louisiana’s 2nd Congressional District to complete a passport application on-site with the help of staff and government workers.

'Come apply for your passport, no appointment is required'

"Hey #LA02," Rep. Troy A. Carter Sr. (D-LA), whose office co-hosted the event alongside the city of New Orleans, wrote to his followers on Instagram  (META) . "My office is providing passport services at our #PassportAcceptance event. Come apply for your passport, no appointment is required."

More Travel:

The event was held on March 14 from 10 a.m. to 1 p.m. While it was designed for those who are already eligible for U.S. citizenship rather than as a way to help non-citizens with immigration questions, it helped those completing the application for the first time fill out forms and make sure they have the photographs and identity documents they need. The passport offices in New Orleans where one would normally have to bring already-completed forms have also been dealing with lines and would require one to book spots weeks in advance.

These are the countries with the highest-ranking passports in 2024

According to Carter Sr.'s communications team, those who submitted their passport application at the event also received expedited processing of two to three weeks (according to the State Department's website, times for regular processing are currently six to eight weeks).

While Carter Sr.'s office has not released the numbers of people who applied for a passport on March 14, photos from the event show that many took advantage of the opportunity to apply for a passport in a group setting and get expedited processing.

Every couple of months, a new ranking agency puts together a list of the most and least powerful passports in the world based on factors such as visa-free travel and opportunities for cross-border business.

In January, global citizenship and financial advisory firm Arton Capital identified United Arab Emirates as having the most powerful passport in 2024. While the United States topped the list of one such ranking in 2014, worsening relations with a number of countries as well as stricter immigration rules even as other countries have taken strides to create opportunities for investors and digital nomads caused the American passport to slip in recent years.

A UAE passport grants holders visa-free or visa-on-arrival access to 180 of the world’s 198 countries (this calculation includes disputed territories such as Kosovo and Western Sahara) while Americans currently have the same access to 151 countries.

Fast-food chain closes restaurants after Chapter 11 bankruptcy

Several major fast-food chains recently have struggled to keep restaurants open.

Published

on

Competition in the fast-food space has been brutal as operators deal with inflation, consumers who are worried about the economy and their jobs and, in recent months, the falling cost of eating at home. 

Add in that many fast-food chains took on more debt during the covid pandemic and that labor costs are rising, and you have a perfect storm of problems. 

It's a situation where Restaurant Brands International (QSR) has suffered as much as any company.

Three major Burger King franchise operators filed for bankruptcy in 2023, and the chain saw hundreds of stores close. It also saw multiple Popeyes franchisees move into bankruptcy, with dozens of locations closing.

RBI also stepped in and purchased one of its key franchisees.

"Carrols is the largest Burger King franchisee in the United States today, operating 1,022 Burger King restaurants in 23 states that generated approximately $1.8 billion of system sales during the 12 months ended Sept. 30, 2023," RBI said in a news release. Carrols also owns and operates 60 Popeyes restaurants in six states." 

The multichain company made the move after two of its large franchisees, Premier Kings and Meridian, saw multiple locations not purchased when they reached auction after Chapter 11 bankruptcy filings. In that case, RBI bought select locations but allowed others to close.

Another fast-food chain faces bankruptcy problems

Bojangles may not be as big a name as Burger King or Popeye's, but it's a popular chain with more than 800 restaurants in eight states.

"Bojangles is a Carolina-born restaurant chain specializing in craveable Southern chicken, biscuits and tea made fresh daily from real recipes, and with a friendly smile," the chain says on its website. "Founded in 1977 as a single location in Charlotte, our beloved brand continues to grow nationwide."

Like RBI, Bojangles uses a franchise model, which makes it dependent on the financial health of its operators. The company ultimately saw all its Maryland locations close due to the financial situation of one of its franchisees.

Unlike. RBI, Bojangles is not public — it was taken private by Durational Capital Management LP and Jordan Co. in 2018 — which means the company does not disclose its financial information to the public. 

That makes it hard to know whether overall softness for the brand contributed to the chain seeing its five Maryland locations after a Chapter 11 bankruptcy filing.

Bojangles has a messy bankruptcy situation

Even though the locations still appear on the Bojangles website, they have been shuttered since late 2023. The locations were operated by Salim Kakakhail and Yavir Akbar Durranni. The partners operated under a variety of LLCs, including ABS Network, according to local news channel WUSA9

The station reported that the owners face a state investigation over complaints of wage theft and fraudulent W2s. In November Durranni and ABS Network filed for bankruptcy in New Jersey, WUSA9 reported.

"Not only do former employees say these men owe them money, WUSA9 learned the former owners owe the state, too, and have over $69,000 in back property taxes."

Former employees also say that the restaurant would regularly purchase fried chicken from Popeyes and Safeway when it ran out in their stores, the station reported. 

Bojangles sent the station a comment on the situation.

"The franchisee is no longer in the Bojangles system," the company said. "However, it is important to note in your coverage that franchisees are independent business owners who are licensed to operate a brand but have autonomy over many aspects of their business, including hiring employees and payroll responsibilities."

Kakakhail and Durranni did not respond to multiple requests for comment from WUSA9.

From the Fed: Industrial Production and Capacity Utilization
Industrial production edged up 0.1 percent in February after declining 0.5 percent in January. In February, the output of manufacturing rose 0.8 percent and the index for mining climbed 2.2 percent. Both gains partly reflected recoveries from weather-related declines in January. The index for utilities fell 7.5 percent in February because of warmer-than-typical temperatures. At 102.3 percent of its 2017 average, total industrial production in February was 0.2 percent below its year-earlier level. Capacity utilization for the industrial sector remained at 78.3 percent in February, a rate that is 1.3 percentage points below its long-run (1972–2023) average.
