The perfect storm of soaring fuel costs and intensified global demand has caused major volatility and rapid escalations of construction material costs. Despite these obstacles, experienced builders have a variety of solutions they can provide companies to offset the escalating material costs and still develop new facilities for growth and expansion. In a recent white paper titled "Smart Construction," Leopardo Construction highlights 10 economical building solutions for offsetting the skyrocketing material prices and realigning construction budgets with original expectations.
Since January 2004, the price per gallon of gasoline at the pump has risen 167 percent and diesel fuel has jumped 252 percent. The cost of fuel has a tremendous impact on petroleum-based materials such as plastic, asphalt, rubber, PVC, insulation and roofing shingles. The price of asphalt, for instance, increased 47 percent in the last 12 months. Beyond petroleum byproducts, every single construction material requires manufacturing and transportation -- sometimes across thousands of miles -- which consume fuel.

Apartment buildings and houses built on pillars are at high risk in an earthquake . Most such buildings here were constructed in the 1950s, 60s and 70s, when there was less awareness of the relationship between structure and the risk of collapse.
But now researchers in civil engineering at the Ariel University Center in Samaria claim to have developed a way to retrofit pillars to make such buildings safer.
Dr. Yuri Ribakov and engineer Vladimir Briman published an article in the international journal The Structural Design of Tall and Special Buildings (www3.interscience.wiley.com/journal/120847777/abstract). They suggest replacing existing exposed pillars with improved versions. The old ones are replaced by structures that carry the building's weight until the new ones are installed

BEIJING: This ancient capital city , long known for the architectural splendor of its centuries-old palaces and temples, is getting a new look that could have been plucked from science fiction.
A series of landmarks, notable for their futuristic design, will greet visitors to the Olympics. They include an Olympic stadium that looks like a giant bird's nest, a swimming venue literally built of bubbles and a pair of black office towers that lean toward each other at a 10-degree angle.

VANCOUVER - Seismically upgrading Vancouver city hall would be expensive and could change the look of the heritage building, so engineers are considering an innovative way to save it during an earthquake: lifting up the structure and putting a rubber foundation underneath.
The rubber would absorb the vibrations of a large tremor and protect the old building from being too badly damaged, said Garrick Bradshaw, city hall's director of facility design and management.

Canada's construction industry is being pushed to its limits, a new report says.
And the pressure is only going to get worse before it gets better, with 162,000 workers needed to replace retiring Baby Boomers, according to an assessment of Canada's construction labour markets from 2008 to 2016 by the Ottawa-based Construction Sector Council (CSC).
Another 94,000 construction workers will be needed over the next eight years just to keep pace with new projects. These numbers are above and beyond the 42,000 workers hired last year, a figure the CSC calls unprecedented.
"From 2007 to 2016, that's close to 300,000 construction workers. The magnitude of that should be a call to action," says CSC executive director George Gritziotis.

NEW YORK — An Italian architect said he is poised to start construction on a new skyscraper in Dubai that will be "the world's first building in motion," an 80-story tower with revolving floors that give it an ever-shifting shape.
The spinning floors, hung like rings around an immobile cement core, would offer residents a constantly changing view of the Persian Gulf and the city's futuristic skyline.
A few penthouse villas would spin on command using a voice-activated computer. The motion of the rest of the building would be choreographed in patterns that could be altered over time.
Speaking at a news conference in New York on Tuesday, the building's designer, David Fisher, declared that his tower will revolutionize the way skyscrapers are made — a claim that might strike some as excessively bold.

“The problem is the building codes. They’re standing in the way of green building, and forcing us to build standardized structures that are bad for the environment.”
Like many half truths, this familiar lament of people who want to “build green” is based on some real obstacles to green building, but also on some fundamental misunderstandings of what building codes do and don’t allow.

LAHORE: An old Hindu temple of historical significance situated in the east of Thokar Niaz Beg, called the Bhadhar Kali Mandar , is facing decay and destruction.
The exact date of the construction of this mandar has not been deciphered but according to the founder of Punjabi research institute, Khojgarh, Mr Iqbal Kaisar it has to be around 2000 years old. The temple has one central building, with a huge pool in the center of the main complex. The walls of the mandar had beautiful frescoes, some of which have managed to survive over the years. The stone pool was fed by 12 wells through an indigenous drainage system.

The historic urge to view Kew Gardens from a great height has found its ultimate expression in a new Treetop Walkway
In 1761, work began on the construction of William Chambers’ Chinese Pagoda at Kew — a 10-storey structure built as a surprise present for Princess Augusta, mother of George III.
As it rose towards its ultimate height of 50m, it was observed by Horace Walpole from his house at Strawberry Hill on the far side of the Thames. “We begin to perceive the tower of Kew from Montpelier Road,” he wrote to a friend. “In a fortnight you will be able to see it in Yorkshire.”

WEST LAFAYETTE, Ind.- Engineers from Purdue and Notre Dame universities are working with Indiana startup EmNet LLC on a wireless sensor network for the city of South Bend to prevent raw sewage from overflowing into waterways, especially from surging runoff during storms.
The system will use a citywide network of 105 manhole-mounted sensors and "smart valves" to automatically hold back the flow of rainwater and sewage in existing sewer system pipes and retention basins until the storm has passed.
"To our knowledge, this monitoring system will be the first of its kind in the world because it will be the largest wireless sensor network in a permanent, industrial setting," said Luis Montestruque, CEO of EmNet, founded in 2004 and located in Granger, Ind.
The system, called CSOnet, consists of numerous computer chips that communicate with each other over a wireless radio network. These microcomputers are embedded in the city sewer system and are connected to flow sensors, pressure sensors and valves in a network that works in a cooperative manner to control storm runoff, Montestruque said.

Construction work on one of South Korea's biggest infrastructure links is in full swing, with substructure erection of the two main bridges under way and the first units of the immersed tube tunnel in place. Don Fraser reports on progress so far
When the new link from the Korean mainland to the island of Geoje opens in December 2010, the journey time between them will be slashed by two hours. The 8.2km-long transport connection will provide a four-lane highway link from Busan, South Korea’s second largest city, to the island of Geoje, home to two of the world’s largest shipyards. Two cable-stayed bridges and an immersed tunnel will take vehicles on an island-hopping route across water depths of up to 40m, at a site exposed to severe open sea conditions from the Pacific Ocean (Bd&e issue no 43). The US$2.5 billion fixed link is being built by GK Corporation, a seven-contractor consortium led by Daewoo Engineering & Construction. A joint-venture of Halcrow and TEC is providing technical consulting services to Daewoo E&C, in a design team led by Cowi.

About one mile out from the shore of the Chesapeake Bay stands the nation's last operational screw-pile foundation lighthouse in its original location — Maryland's Thomas Point Shoal Lighthouse. The 43-foot-tall lighthouse has withstood the most tremendous weather conditions of the Bay and South River since 1875. Located about four miles from Annapolis, Md., the lighthouse is a beacon of safety for vessels traveling the bay. It was constructed offshore to alert watercraft operators of the dangerous shoal near the coastline to the west. The Victorian cottage-style lighthouse, nested atop a hexagonal foundation, has also served as a weather center for many boats that have serviced the Chesapeake Bay waterways. Before 1986, when it became fully automated, Maryland's Thomas Point Shoal Lighthouse was the last of its kind to operate manually. The significance of this lighthouse is so great that it was awarded National Historic Landmark status in 1999.
